Understanding Cloud Concepts

More and more organizations are using cloud resources for a wide variety of benefits. If you’re planning to take the SY0-501 version of the Security+ exam, you should have a basic understanding of cloud concepts.

For example, can you answer this question?

Q. The Springfield Nuclear Power Plant has created an online application teaching nuclear physics. Only students and teachers in the Springfield Elementary school can access this application via the cloud. What type of cloud service model is this?

A. IaaS

B. PaaS

C. SaaS

D. Public

More, do you know why the correct answer is correct and the incorrect answers are incorrect? The answer and explanation are available at the end of this post.

Cloud computing refers to accessing computing resources via a different location than your local computer. In most scenarios, you’re accessing these resources through the Internet.

Understanding Cloud Concepts

Software as a Service

Software as a Service (SaaS) includes any software or application provided to users over a network such as the Internet. Internet users access the SaaS applications with a web browser. It usually doesn’t matter which web browser or operating system a SaaS customer uses. They could be using Microsoft Edge, Chrome, Firefox, or just about any web browser.
As mentioned previously, web-based email is an example of SaaS. This includes Gmail, Yahoo! Mail, and others. The service provides all the components of email to users via a simple web browser.

If you have a Gmail account, you can also use Google Docs, another example of SaaS. Google Docs provides access to several SaaS applications, allowing users to open text documents, spreadsheets, presentations, drawings, and PDF files through a web browser.

A talented developer and I teamed up to work on a project a while ago. He’s an Apple guy running a macOS while I’m a Microsoft guy running Windows, and we live in different states. However, we post and share documents through Google Docs and despite different locations and different applications running on our individual systems, we’re able to easily collaborate. One risk is that our data is hosted on Google Docs, and if attackers hack into Google Docs, our data may be compromised.

Platform as a Service

Platform as a Service (PaaS) provides customers with a preconfigured computing platform they can use as needed. It provides the customer with an easy-to-configure operating system, combined with appropriate applications and on-demand computing.

Many cloud providers refer to this as a managed hardware solution. For example, I host http://gcgapremium.com/ on a virtual server through Liquid Web (http://www.liquidweb.com/) using one of their “Fully Managed” offerings.

Liquid Web provides several features in their fully managed solutions, including an installed operating system, a core software package used for web servers, Apache as a web server, antivirus software, spam protection, and more. Additionally, they keep the operating system up to date with relevant updates and patches. I manage the software used for the web site, including software changes and updates. However, I don’t need to worry about managing the server itself. The couple of times when the server developed a problem, they fixed it before I was even aware of the problem.

Infrastructure as a Service

Infrastructure as a Service (IaaS) allows an organization to outsource its equipment requirements, including the hardware and all support operations. The IaaS service provider owns the equipment, houses it in its data center, and performs all the required hardware maintenance. The customer essentially rents access to the equipment and often pays on a per-use basis.

Many cloud providers refer to this as a self-managed solution. They provide access to a server with a default operating system installation, but customers must configure it and install additional software based on their needs. Additionally, customers are responsible for all operating system updates and patches.

IaaS can also be useful if an organization is finding it difficult to manage and maintain servers in its own data center. By outsourcing its requirements, the company limits its hardware footprint. It can do this instead of, or in addition to, virtualizing some of its servers. With IaaS, it needs fewer servers in its data center and fewer resources, such as power, HVAC, and personnel to manage the servers.

Security as a Service

Another entry into cloud computing is Security as a Service. It includes any services provided via the cloud that provide security services, and is commonly viewed as a subset of the Software as a Service (SaaS) model.

A common example of a Security as a Service application is antivirus software. Imagine radio station W-KOMA decides to purchase antivirus software for its eight employees. They purchase licenses to access the software from an antivirus company. Each employee then configures their system to use the software with their individual licenses. Once installed, the software automatically downloads virus definitions keeping each user’s system up to date without relying on the user to do so.

A key benefit of Security as a Service is that it outsources the administrative tasks associated with implementing the service. Additionally, professionals are focused on the specific security services offered, eliminating the need for employees to be experts on everything.

Organizations that use cloud resources often add a cloud access security broker (CASB) for additional security. This is a software tool or service deployed between an organization’s network and the cloud provider. It monitors all network traffic and can enforce security policies. As an example, it can ensure that all data stored in the cloud is encrypted.

Q. The Springfield Nuclear Power Plant has created an online application teaching nuclear physics. Only students and teachers in the Springfield Elementary school can access this application via the cloud. What type of cloud service model is this?

A. IaaS

B. PaaS

C. SaaS

D. Public

Answer is C. This is a Software as a Service (SaaS) model. The software is the online application and the cloud provider (the Springfield Nuclear Power Plant in this example) maintains it.

Infrastructure as a Service (IaaS) provides customers with the hardware via the cloud. Customers are responsible for installing the operating system and any applications.

Platform as a Service (PaaS) is a computing platform. For example, a cloud provider can provide a server with a preconfigured operating system.

Anyone can access a public cloud. However, the question states that only students and teachers can access it.

Secure Coding Practices

If you’re planning to take the SY0-501 version of the Security+ exam, you should have a basic understanding of secure coding practices. Secure application development and deployment concepts are important for application developers to understand. Additionally, IT security managers who manage development projects should understand these concepts, too, even if they aren’t writing the code.

For example, can you answer this question?

Q. You are overseeing a large software development project. Ideally, developers will not add any unauthorized changes to the code. If they do, you want to ensure that it is easy to identify the developer who made the change. Which of the following provides the BEST solution for this need?

A. Agile SDLC

B. Version control

C. Secure DevOps

D. Static code analysis

More, do you know why the correct answer is correct and the incorrect answers are incorrect? The answer and explanation are available at the end of this post.

Secure DevOps

DevOps combines the words development and operations and it is an agile-aligned software development methodology. Secure DevOps is a software development process that includes extensive communication between software developers and operations personnel. It also includes security considerations throughout the project. When applied to a software development project, it can allow developers to push out multiple updates a day in response to changing business needs.

Some of the concepts included within a secure DevOps project are summarized in the following bullets:

Security automation uses automated tests to check code. When modifying code, it’s important to test it and ensure that the code doesn’t introduce software bugs or security flaws. It’s common to include a mirror image of the production environment and run automated tests on each update to ensure it is error free.

Continuous integration refers to the process of merging code changes into a central repository. Software is then built and tested from this central repository. The central repository includes a version control system, and the version control system typically supports rolling back code changes when they cause a problem.

Baselining refers to applying changes to the baseline code every day and building the code from these changes. For example, imagine five developers are working on different elements of the same project. Each of them have modified and verified some code on their computers. At the end of the day, each of these five developers uploads and commits their changes. Someone then builds the code with these changes and then automation techniques check the code. The benefit is that bugs are identified and corrected quicker. In contrast, if all the developers applied their changes once a week, the bugs can multiply and be harder to correct.

Immutable systems cannot be changed. Within the context of secure DevOps, it’s possible to create and test systems in a controlled environment. Once they are created, they can be deployed into a production environment. As an example, it’s possible to create a secure image of a server for a specific purpose. This image can be deployed as an immutable system to ensure it stays secure.

Infrastructure as code refers to managing and provisioning data centers with code that defines virtual machines (VMs). Once the script is created, new VMs can be created just by running the script.

Secure Coding Practices

Version Control and Change Management

The primary purpose of change management policies is to ensure that changes to systems do not cause unintended outages. Secure coding practices use version control and change management practices for the same reason—to prevent unintended outages.

Change management helps ensure that developers do not make unauthorized changes. As an example, if a customer wants a change or addition to the application, a developer doesn’t just implement it, no matter how easy it might be to do so. Instead, any changes to the application go through a specific, predefined process.

The change management process allows several people to examine the change to ensure it won’t cause unintended consequences. Also, any change to the application becomes an added responsibility. If the customer discovers a bug due to this change after it’s delivered, the developer may be responsible for fixing it, even if it wasn’t authorized.

In addition to preventing unauthorized changes and related problems, a change management process also provides an accounting structure to document the changes. Once a change is authorized and implemented, the change is documented in a version control document.

Version control tracks the versions of software as it is updated, including who made the update and when. Many advanced software development tools include sophisticated version control systems. Developers check out the code to work on it and check it back into the system when they’re done. The version control system can then document every single change made by the developer. Even better, this version control process typically allows developers to roll back changes to a previous version when necessary.

Jamming Attacks

Attackers can transmit noise or another radio signal on the same frequency used by a wireless network. This interferes with the wireless transmissions and can seriously degrade performance. This type of denial-of-service attack is commonly called jamming and it usually prevents all users from connecting to a wireless network. In some cases, users have intermittent connectivity because the interference causes them to lose their association with the AP and forces them to try to reconnect.

In some cases, you can increase the power levels of the AP to overcome the attack. Another method of overcoming the attack is to use different wireless channels. Each wireless standard has several channels you can use, and if one channel is too noisy, you can use another one. Although this is useful to overcome interference in home networks, it won’t be as effective to combat an interference attack. If you switch channels, the attacker can also switch channels.Attacks Against Wireless Networks

NFC Attacks

Near field communication (NFC) is a group of standards used on mobile devices that allow them to communicate with other mobile devices when they are close to them. For example, you can share pictures, contacts, and other data with friends. One person shares the data, and after placing the smartphones close to each other, the other person selects it to download.

During an NFC attack, an attacker uses an NFC reader to capture data from another NFC device. One method is an eavesdropping attack. The NFC reader uses an antenna to boost its range, and intercepts the data transfer between two other devices.

A more advanced attack was discovered by security researchers in 2012. They designed Trojan malware and installed it on an Android-based smartphone. They used the Trojan to initiate a payment. The NFC reader was then able to capture the payment data and use it in a live payment transaction. Google quickly modified Google Wallet to prevent this type of attack.

The range of Bluetooth was originally designed for about three meters (about 10 feet), but the range is often farther, and ultimately extends beyond a person’s personal space. Attackers have discovered methods of exploiting these networks. Some common attacks are bluejacking, bluesnarfing, and bluebugging:

Bluejacking is the practice of sending unsolicited messages to nearby Bluetooth devices. Bluejacking messages are typically text, but can also be images or sounds. Bluejacking is relatively harmless, but does cause some confusion when users start receiving messages.
Bluesnarfing refers to the unauthorized access to, or theft of information from, a Bluetooth device. A bluesnarfing attack can access information, such as email, contact lists, calendars, and text messages. Attackers use tools such as hcitool and obexftp.
Bluebugging is like bluesnarfing, but it goes a step further. In addition to gaining full access to the phone, the attacker installs a backdoor. The attacker can have the phone call the attacker at any time, allowing the attacker to listen in on conversations within a room. Attackers can also listen in on phone conversations, enable call forwarding, send messages, and more.

When Bluetooth devices are first configured, they are configured in Discovery mode. Bluetooth devices use MAC addresses, and in Discovery mode the Bluetooth device broadcasts its MAC address, allowing other devices to see it and connect to it. This is required when pairing Bluetooth devices.

In earlier versions of Bluetooth, this pairing process could happen any time a device is in Discovery mode. However, most software vendors have rewritten their software to prevent this. Today, users typically manually pair the device. If a user doesn’t acknowledge an attempted pairing, it fails. As a result, Bluetooth attacks are rare today. However, if a device doesn’t require a user to manually pair a device, it is still susceptible to these attacks.

Wireless Replay Attacks

In a replay attack, an attacker captures data sent between two entities, modifies it, and then attempts to impersonate one of the parties by replaying the data. WPA2 using CCMP and AES is not vulnerable to replay attacks. However, WPA using TKIP is vulnerable to replay attacks.

WPA uses a sequence counter to number the packets and an access point will reject packets received out of order. Additionally, TKIP uses a 64-bit Message Integrity Check (MIC) to verify the integrity of the packets. While this sounds secure, security experts identified a method to discover the MIC key. After discovering the key, an attacker can transmit and decrypt packets. Later, other security experts improved this attack allowing them to launch a replay attack. This is one of the reasons that TKIP was deprecated in 2012 and should not be used.


Q. Mobile users in your network report that they frequently lose connectivity with the wireless network on some days, but on other days they don’t have any problems. You suspect this is due to an attack. Which of the following attacks is MOST likely causing this problem?

A. Wireless jamming

B. IV

C. Replay

D. Bluesnarfing

Answer is A. A wireless jamming attack is a type of denial-of-service (DoS) attack that can cause wireless devices to lose their association with access points and disconnect them from the network. None of the other attacks are DoS attacks.

An initialization vector (IV) attack attempts to discover the passphrase.

A replay attack captures traffic with the goal of replaying it later to impersonate one of the parties in the original transmission.

Bluesnarfing is a Bluetooth attack that attempts to access information on Bluetooth devices.

See Chapter 4 of the CompTIA Security+: Get Certified Get Ahead: SY0-501 Study Guide for more information on wireless attacks.

Deploying Mobile Devices Securely

Mobile devices represent significant challenges for organizations today. Organizations need to determine if employees can connect mobile devices to the network. If so, organizations need to identify methods to manage the security related to the devices, and how to monitor the devices and enforce security policies.

What is a mobile device? Within the context of the CompTIA Security+ exam, you can think of a mobile device as a smartphone or tablet. Further, NIST SP 800-124,“Guidelines for Managing the Security of Mobile Devices in the Enterprise,” mentions that mobile devices have additional characteristics, such as at least one wireless network interface, local data storage, an operating system (that isn’t a full-fledged desktop or laptop operating system), and the ability to install additional applications.

Mobile devices typically have other optional features. This includes other networking options such as Bluetooth, near field communication, cellular access for voice communications, and Global Positioning System (GPS) services. They typically include a digital camera, a video recorder, a microphone, and the ability to transfer data to another system such as a traditional computer or to other mobile devices.

The NIST definition excludes many devices. For example, a laptop is not considered a mobile device within this definition. Laptops have full operating systems and there are many security controls available for them, which aren’t available in smartphones and tablets. Additionally, basic cell phones and digital cameras are not included in this definition because they cannot access networks and aren’t susceptible to the same risks associated with smartphones and tablets.

Deployment Models

Any device connected to an organization’s network represents a potential risk. As a simple example, if someone connects an infected device to a network, it might be able to infect other devices on the network. To limit this risk, organizations take steps to monitor and manage mobile devices.

If the organization owns all the devices connected to the network, it’s a simple matter to monitor and manage them. However, if employees own these devices (such as their own smartphone), monitoring and managing the devices becomes more challenging. As an example, employees want to access the network resources with their own device, but they are sometimes resistant to allowing the organization to monitor and manage their personal device.

Mobile Device Deployment Models

The following list identifies some common deployment models for mobile devices. Notice that in some models, the organization owns the device, but in other models, employees own the device:

  • Corporate-owned. In this traditional deployment model, the organization purchases devices and issues them to employees.
  • COPE (corporate-owned, personally enabled). COPE is similar to the traditional corporate-owned model, but the primary difference is that the employees are free to use the device as if it was their personally owned device. This allows employees to use the devices for personal activities in addition to connecting them to the organization’s network. Because the organization owns the devices, it makes it easier to manage them.
  • BYOD (bring your own device). Some organizations allow employees to bring their own mobile devices to work and attach them to the network. Employees are responsible for selecting and supporting the device and they typically must comply with a BYOD policy when connecting their device to the network. While this is simple for the employees, it is sometimes referred to as bring your own disaster among IT professionals. Because employees can have any possible device, the IT department is now responsible for supporting, monitoring, and managing any possible device owned by employees.
  • CYOD (choose your own device). To avoid some of the challenges related to supporting any possible mobile devices, some organizations create a list of acceptable devices along with a CYOD policy. Employees can purchase devices on the list and bring them to work. This gives the IT department a specific list of devices that they need to support, monitor, and manage.
  • VDI (virtual desktop infrastructure). VDIs host a user’s desktop operating system on a server. While these are typically accessed by traditional computers within a network, it’s also possible to deploy a VDI that users can access with their mobile device. This allows users to access any applications installed on their desktop. When the organization hosts a remote access solution such as a virtual private network (VPN), users can access the mobile VDI from anywhere if they have Internet access.

The use of mobile devices has exploded in the last few years with more and more organizations allowing employees to connect mobile devices to the network. This results in many challenges for an organization, but mobile device management tools help administrators handle these challenges.

Q. Management decided last year to allow employees to connect and use their personal mobile devices on the internal network. However, the organization is having problems with these devices including the following:

  • Employees do not keep their devices updated.
  • There is no standardization among the devices.
  • The organization doesn’t have adequate control over the devices.

Management wants to implement a mobile device deployment model to overcome these problems, while still allowing employees to use their own devices. Which of the following is the BEST choice?

A. BYOD

B. COPE

C. CYOD

D. SaaS

Answer is C. A choose your own device mobile device model includes a list of acceptable devices that employees can purchase and connect to the network. IT management can then implement a mobile device management (MDM) system to provide standardized management for these devices.

The current policy is a bring your own device (BYOD) policy, but because of the lack of standardization, it’s extremely difficult for IT departments to adequately manage the devices and ensure they don’t introduce vulnerabilities to the network.

A corporate-owned personally enabled (COPE) indicates the organization owns the devices, not the employees.

Software as a Service (SaaS) is a cloud deployment model, not a mobile device deployment model.

See Chapter 5 of the CompTIA Security+ Get Certified Get Ahead: SY0-501 Study Guide for more information on securing hosts and data.

Secure Systems Design

Secure systems design concepts help ensure that computing systems are deployed and maintained in a secure state. If you’re planning to take the SY0-501 version of the Security+ exam, you should have a basic understanding related to secure systems design.

For example, can you answer this question?

Q. Attackers recently attacked a web server hosted by your organization. Management has tasked administrators with configuring the servers following the principle of least functionality. Which of the following will meet this goal?

A. Disabling unnecessary services

B. Installing and updating antivirus software

C. Identifying the baseline

D. Installing a NIDS

More, do you know why the correct answer is correct and the incorrect answers are incorrect? The answer and explanation are available at the end of this post.

Implementing Secure Systems

Secure systems design concepts help ensure that computing systems are deployed and maintained in a secure state. In this context, a system is any host such as a server, workstation, laptop, network device, or mobile device. In an ideal world, systems start in a secure state. Unfortunately, it’s not an ideal world, and administrators need to be proactive to secure systems before deployment and keep them secure after deployment.

Hardening is the practice of making an operating system (OS) or application more secure from its default installation. It helps eliminate vulnerabilities from default configurations, misconfigurations, and weak configurations.

A core principle associated with secure systems design is least functionality. Systems should be deployed with only the applications, services, and protocols they need to meet their purpose. If a service or protocol is not running on a system, attackers cannot attack it. As a simple example, a system is not vulnerable to any File Transfer Protocol (FTP) attacks if FTP is not running and available on the system.

In addition to disabling unnecessary services to reduce vulnerabilities, it’s important to uninstall unneeded software. Software frequently has bugs and vulnerabilities. Although patching software frequently closes these vulnerabilities, you can eliminate these vulnerabilities by simply eliminating unneeded applications.

Secure Systems Design

Years ago, I was working at a small training company. One of the servers had a default configuration for Windows that resulted in a significant vulnerability. We were using the server as a file server, but because it wasn’t hardened from the default configuration, it was also running Internet Information Services (IIS), the Microsoft web server.

At some point, attackers released the Nimda virus, which exploited a vulnerability with IIS. Microsoft released a patch for IIS, but because IIS was installed by default and we weren’t using it, we also weren’t managing it. Ultimately, the Nimda virus found our server, and the worm component of Nimda quickly infected our network. If the IIS software hadn’t been installed, the server would not have been vulnerable to the attack.
It’s also important to disable unnecessary accounts. For example, the Guest account is disabled by default in current Windows systems and it should remain disabled unless there is a specific need for it.

Some applications also include backdoor accounts. A backdoor is an access point to an application or service that bypasses normal security mechanisms. Developers use backdoors for legitimate purposes to view the internal workings of an application or for ease of administration. However, the use of backdoors is strongly discouraged in the final released version. If a backdoor exists, you can expect attackers to locate and exploit it. Similarly, if a system or application has a default account with a default password, the password should be changed.

Operating Systems

There are three primary types of computer operating systems (OSs): Windows, Apple’s operating systems, and Linux- or Unix-based systems.

Within these types, there are many different versions. For example, the Windows operating system includes versions for desktop workstations (including laptops) and other versions for servers. Additionally, these versions are regularly updated such as Windows 8 and Windows 10, and Windows Server 2012 and Windows Server 2016. Windows operating systems are closed source software, meaning that the underlying code is not freely available to the public. Microsoft developed these OSs and updates them.

Apple also uses closed source OSs—macOS for its Macintosh computers and iOS as a mobile OS for mobile devices such as iPhones and iPads. Because they are closed source, only Apple updates or modifies these OSs.

Linux is derived from Unix and is open source, meaning that it is freely available to anyone. Developers have access to the code and can modify, improve, and, at times, freely redistribute it. Because of this, there is an almost endless assortment of Linux versions. As an example, the Android OS is open source software, and it was derived from the open source Linux OS. Additionally, many mobile device manufacturers modify the Android OS and use it as a mobile OS for their devices. It’s worth noting that the use of Linux in many systems has steadily increased. More, CompTIA has been adding additional Linux-based objectives in their exams, including the Security+ exam.

While you primarily see OSs operating on desktops, laptops, and servers, they are also operating in other locations, including:

Kiosks. A kiosk is a small structure in an open area used to sell something, provide information, or display advertisements. For example, an organization can create a touch-screen application installed on a computer and place it in a kiosk. This could be in a mall or store (designed to advertise something), in a medical center (designed to share information), or anywhere an organization thinks it might be useful.
Network. Many network devices such as switches, routers, and firewalls include an operating system used to manage the device. These are often a version of Linux. Some Cisco network devices use the Cisco IOS (originally called the Internetwork Operating System).
Appliance. A network appliance is a dedicated hardware device that bundles several features within it. As an example, Chapter 3 of the CompTIA Security+: Get Certified Get Ahead: SY0-501 Study Guide discusses a unified threat management (UTM) device that includes multiple layers of protection. Many appliances run on a Linux version.

It’s also possible to use live boot media to create a non-persistent operating system on a computer. As an example, the Defense Information Systems Agency (DISA) uses Bootable Media (BootMe), which is a CD that authorized Department of Defense (DoD) users can use to run an operating system on almost any computer. It provides users with an operating system to perform specific functions, such as accessing DoD resources via remote access. It’s called a non-persistent operating system because it disappears when users turn off the computer.

Q. Attackers recently attacked a web server hosted by your organization. Management has tasked administrators with configuring the servers following the principle of least functionality. Which of the following will meet this goal?

A. Disabling unnecessary services

B. Installing and updating antivirus software

C. Identifying the baseline

D. Installing a NIDS

Answer is A. Disabling unnecessary services is one of the elements of the principle of least functionality. Other elements include deploying the server with only the applications and protocols they need to meet their purpose.

Installing up-to-date antivirus software is a valid preventive control, but it isn’t related to least functionality.

Identifying the baseline should be done after disabling unnecessary services.

A network-based intrusion detection system (NIDS) helps protect the server, but it doesn’t implement least functionality.

See Chapter 5 of the CompTIA Security+: Get Certified Get Ahead: SY0-501 Study Guide for more information on implementing secure systems.

Risk Management

Risk is the likelihood that a threat will exploit a vulnerability. A vulnerability is a weakness, and a threat is a potential danger. The result is a negative impact on the organization. Impact refers to the magnitude of harm that can be caused if a threat exercises a vulnerability.

For example, a system without up-to-date antivirus software is vulnerable to malware. Malware written by malicious attackers is the threat. The likelihood that the malware will reach a vulnerable system represents the risk. Depending on what the malware does, the impact may be an unbootable computer, loss of data, or a remote-controlled computer that has joined a botnet. However, the likelihood of a risk occurring isn’t 100 percent. An isolated system without Internet access, network connectivity, or USB ports has a very low likelihood of malware infection.

The likelihood significantly increases for an Internet-connected system, and it increases even more if a user visits risky web sites and downloads and installs unverified files.

Risk Management Concepts

It’s important to realize that you can’t eliminate risk. Sure, you can avoid information technology (IT) risks completely by unplugging your computer and burying it. However, that wouldn’t be very useful. Instead, users and organizations practice risk management to reduce the risks.

You probably practice risk management every day. Driving or walking down roads and streets can be a very dangerous activity. Car-sized bullets are speeding back and forth, representing significant risks to anyone else on the road. However, you mitigate these risks with caution and vigilance. The same occurs with computers and networks. An organization mitigates risks using different types of security controls.

Threats and Threat Assessments

A threat is a potential danger. Within the context of risk management, a threat is any circumstance or event that can compromise the confidentiality, integrity, or availability of data or a system. Threats come in different forms, including the following:

Malicious human threats. Chapter 6, “Comparing Threats, Vulnerabilities, and Common Attacks,” discusses various types of threat actors. They include relatively inexperienced script kiddies, dedicated criminals working within an organized crime group, and sophisticated advanced persistent threats (APTs) sponsored by a government. These are all malicious human threats. Malicious human threats regularly launch different types of attacks, including network attacks, system attacks, and the release of malware.

Accidental human threats. Users can accidentally delete or corrupt data, or accidentally access data that they shouldn’t be able to access. Even administrators can unintentionally cause system outages. The common cause is by a well-meaning administrator making a configuration change to fix one problem but inadvertently causing another one.

Environmental threats. This includes long-term power failure, which could lead to chemical spills, pollution, or other possible threats to the environment. It also includes natural threats such as hurricanes, floods, tornadoes, earthquakes, landsides, electrical storms, and other similar events.

A threat assessment helps an organization identify and categorize threats. It attempts to predict the threats against an organization’s assets, along with the likelihood the threat will occur. Threat assessments also attempt to identify the potential impact from these threats. Once the organization identifies and prioritizes threats, it identifies security controls to protect against the most serious threats.

Organizations have limited resources, so it’s not possible to protect against all threats. However, threat assessments improve the security posture of any system or application by ensuring that the resources aren’t squandered on low-priority threats. Some common types of threat assessments are:

Environmental. An environmental threat assessment evaluates the likelihood of an environmental threat occurring. For example, I live in Virginia Beach, Virginia, and while we’re concerned about the natural threat of hurricanes during the hurricane season, we aren’t very concerned about earthquakes. My sister is a business continuity expert and she lives near San Francisco and works in Silicon Valley. She helps companies prepare for risks associated with earthquakes there, but she spends very little time or energy considering the risk of a hurricane hitting San Francisco.

Manmade. A manmade threat assessment evaluates all threats from humans. These include both malicious human threats and accidental human threats. A malicious human threat refers to any potential attack from a person or group of people. An accidental human threat refers to any potential loss caused by a person or group accidentally.

Internal. An internal threat assessment evaluates threats from within an organization. This includes threats from malicious employees and threats from accidents. It also includes threats related to hardware failure.

External. An external threat assessment evaluates threats from outside an organization. This includes any threats from external attackers. It also includes any natural threats, such as hurricanes, earthquakes, and tornadoes.

Remember this

A threat is a potential danger and a threat assessment evaluates potential threats. Environmental threats include natural threats such as weather events. Manmade threats are any potential dangers from people and can be either malicious or accidental. Internal threats typically refer to employees within an organization, while external threats can come from any source outside the organization.

Q. Ziffcorp is developing a new technology that they expect to become a huge success when it’s released. The CIO is concerned about someone stealing their company secrets related to this technology. Which of the following will help the CIO identify potential dangers related to the loss of this technology?

A. Threat assessment

B. Vulnerability assessment

C. Privacy threshold assessment

D. Privacy impact assessment

Answer is A. A threat assessment evaluates potential dangers that can compromise the confidentiality, integrity, and/or availability of data or a system. It evaluates threats and attempts to identify the potential impact from threats.

A vulnerability assessment evaluates vulnerabilities (or weaknesses), not potential dangers.

A privacy threshold assessment helps an organization identify Personally Identifiable Information (PII) within a system and a privacy impact assessment attempts to identify potential risks related to PII. However, this scenario doesn’t mention PII.
