Physical Security Measures

If you’re planning to take the SY0-501 version of the Security+ exam, you should understand the importance of physical security controls. Physical security access controls attempt to control entry and exits, and organizations commonly implement different controls at different boundaries

Here’s a Security+ practice test question:

Q. A security expert is identifying and implementing several different physical deterrent controls to protect an organization’s server room. Which of the following choices would BEST meet this objective?

A. Using hardware locks

B. Utilizing data encryption

C. Performing a vulnerability assessment

D. Training users

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.

You can implement simple physical security measures to prevent access to secure areas. For example, you can use hardware locks—similar to what you use to secure your home—to secure buildings as well as rooms within buildings. Companies that don’t have the resources to employ advanced security systems often use these types of hardware locks.

Instead of allowing free access to wiring closets or small server rooms, small organizations use these types of locks to restrict access. Although these locks aren’t as sophisticated as the ones used by large organizations, they are much better than leaving the rooms open and the equipment exposed.

Key management is an important concept to consider when using hardware locks. Proper key management ensures that only authorized personnel can access the physical keys. This might be done by locking keys within a safe or locking cabinet.Physical Security Measures

Securing Mobile Computers with Cable Locks

Cable locks are a great theft deterrent for mobile computers, and even many desktop computers at work. Computer cable locks work similar to how a bicycle cable lock works. However, instead of securing a bicycle to a bike rack or post, a computer cable lock secures a computer to a piece of furniture.

The user wraps the cable around a desk, table, or something heavy, and then plugs it into an opening in the laptop specifically created for this purpose. Most cable locks have a four-digit combo. If you (or anyone) remove the cable lock without the combo, it will likely destroy the laptop.

Another common use of cable locks is for computers in unsupervised labs. For example, you can secure laptop or desktop computers with cable locks in a training lab. This allows you to leave the room open so that students can use the equipment, but the cable locks prevent thieves from stealing the equipment.

Securing Servers with Locking Cabinets

Larger companies often have large server rooms with advanced security to restrict access. Additionally, within the server room, administrators use locking cabinets or enclosures to secure equipment mounted within the bays. An equipment bay is about the size of a large refrigerator and can hold servers, routers, and other IT equipment. These bays have doors in the back and many have doors in the front, too. Administrators lock these doors to prevent unauthorized personnel from accessing the equipment.

Offices often have file cabinets that lock, too, so it’s important to pay attention to the context when referring to locking cabinets. For example, if you want to secure equipment within a server room, a locking cabinet is one of many physical security controls you can use. If you want to secure unattended smartphones in an office space, you can also use a locking cabinet, but this is an office file cabinet that locks.

A. Using hardware locks

B. Utilizing data encryption

C. Performing a vulnerability assessment

D. Training users

Answer is A. hardware lock is a physical security control. It’s also a deterrent control because it would deter someone from entering.

Data encryption is a technical control designed to protect data and is not a physical security control.

A vulnerability assessment is a management control designed to discover vulnerabilities, but it is not a physical control. Training users is an effective preventive control, but it is not a physical control.

Rogue AP

A rogue access point (rogue AP) is an AP placed within a network without official authorization. It might be an employee who is bypassing security or installed by an attacker. If an employee installs a rogue AP, the chances are higher that this AP will not be managed properly, increasing vulnerabilities to the network.

Generically, you can think of a rogue as a scoundrel, a crook, or a villain. Clearly, if a rogue is a crook or villain, then rogue access points are not an administrator’s friend. You might also see them called counterfeit access points, which is also a clear indication they aren’t legitimate.

Identifying Legitimate Access Point

Attackers may connect a rogue access point to network devices in wireless closets that lack adequate physical security. This access point acts as a sniffer to capture traffic passing through the wired network device, and then broadcasts the traffic using the wireless capability of the AP. The attacker can then capture the exfiltrated data files while sitting in the parking lot. Data exfiltration is the unauthorized transfer of data from an organization to a location controlled by an attacker.

Additionally, attackers may be able to use the rogue access point to connect into the wired network. This works the same way that regular users can connect to a wired network via a wireless network. The difference is that the attacker configures all the security for the counterfeit access point and can use it for malicious purposes.

If you discover an unauthorized AP, you should disconnect it as quickly as possible. A basic first step to take when you discover any attack is to contain or isolate the threat. By simply unplugging the Ethernet cable, you can stop the unauthorized AP from capturing network traffic.

Evil Twin

An evil twin is a rogue access point with the same SSID as a legitimate access point. For example, many public places such as coffee shops, hotels, and airports include free Wi-Fi as a service. An attacker can set up an AP using the same SSID as the public Wi-Fi network, and many unsuspecting users will connect to this evil twin.

Once a user connects to an evil twin, wireless traffic goes through the evil twin instead of the legitimate AP. Often, the attacker presents bogus logon pages to users to capture usernames and passwords. Other times, they simply capture traffic from the connection, such as email or text typed into web page text boxes, and analyze it to detect sensitive information they can exploit.

Although it might sound complex to set up an evil twin, it’s rather easy. Attackers can configure a laptop that has a wireless access card as an AP. With it running, the attackers look just like any other user in a coffee shop or airport waiting area. They’ll have their laptop open and appear to be working (just like you perhaps), and you’ll have no idea they are trying to steal your credentials or other personal data that you send over the Internet via the evil twin. Similarly, attackers can set one up in a parking lot or another location close to an organization and try to trick employees or visitors.

Often, administrators will use wireless scanners to perform site surveys. In addition to detecting noise on frequency bands, they can also detect rogue APs, including evil twins. The site survey can help them identify the physical location of access points because the signal will get stronger as the administrator gets closer.

Misconfigured Access Points

One of the primary reasons that wireless attacks are successful is because APs are misconfigured. For example, if an AP is not using WPA2 with AES and CCMP, it is susceptible to many attacks. Similarly, if WPS is enabled on an AP, a WPS attack can discover the PIN in a few hours simply by guessing. After it discovers the PIN, it can discover the passphrase.

Although your wireless router might be a little different, you’ll still be able to see many of the typical configuration settings.

Remember this

Rogue access points are often used to capture and exfiltrate data. An evil twin is a rogue access point using the same SSID as a legitimate access point. A secure AP blocks unauthorized users, but a rogue access point provides access to unauthorized users.

Which of the following is the MOST likely reason why?

A. Rogue AP

B. Evil attacker

C. Jamming

D. Bluejacking

Answer is A. This describes a rogue access point (AP). More specifically, it is an evil twin, which is a rogue AP with the same SSID as a legitimate access point.

While the person setting up the rogue AP may be evil, a CompTIA question won’t ask you to evaluate the character of an attacker.

Jamming typically prevents anyone from connecting to a wireless network.

Bluejacking is related to Bluetooth, not wireless networks.

Discovering Infected Systems

If you’re planning to take the SY0-501 version of the Security+ exam, you should understand different malware types. Attackers install these onto systems using a variety of devious means. Infected systems give various symptoms, such as running slower, starting unknown processes, sending out email without user action, rebooting randomly, and more.

For example, can you answer this question?

Q. A security administrator recently noticed abnormal activity on a workstation. It is connecting to systems outside the organization’s internal network using uncommon ports. The administrator discovered the computer is also running several hidden processes. Which of the following choices BEST describes this activity?

A. Rootkit

B. Backdoor

C. Spam

D. Trojan

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.

Organizations need to understand and protect themselves from many different types of threat actors, so it’s valuable to know a little about them, their attributes, and the types of attacks they are likely to launch. This post compares bots and botnets, and rootkits.

Bots and Botnets

Generically, bots are software robots. For example, Google uses bots as search engine spiders to crawl through the Internet looking for web pages. However, attackers also use bots for malicious purposes. A botnet combines the words robot and network. It includes multiple computers that act as software robots (bots) and function together in a network (such as the Internet), often for malicious purposes. The bots in a botnet are often called zombies and they will do the bidding of whoever controls the botnet.

Bot herders are criminals who manage botnets. They attempt to infect as many computers as possible and control them through one or more servers running command-and-control software. The infected computers periodically check in with the command-and-control servers, receive direction, and then go to work. The user is often unaware of the activity.

Most computers join a botnet through malware infection. For example, a user could download pirated software with a Trojan or click a malicious link, resulting in a drive-by download. The malware then joins the system to a botnet.

Bot herders have been using Mirai to create large botnets. Mirai infects Linux systems that are running out-of-date versions of Linux and join them to a botnet. This includes Linux software running on Internet of things (IoT) devices such as digital cameras connected to the Internet. Infected devices search for other IoT devices on the Internet and infect them. Attackers have published the source code for Mirai in public forums, making it easily accessible by many attackers.

A Mirai botnet launched an attack in October 2016 against Domain Name System (DNS) servers. It included about 100,000 simple devices such as digital cameras and printers that were connected to the Internet. The bot herders directed the devices to repeatedly query DNS servers in a protracted distributed denial-of-service (DDoS) attack. This attack overwhelmed the DNS servers and prevented users in the United States and Europe from accessing many common web sites, such as Amazon, Second Life, Twitter, CNN, BBC, Fox News, Tumblr, Reddit, and many more.

Similarly, Wordfence discovered attacks coming from a botnet of approximately 10,000 separate IP addresses in April 2017. After investigating the attacks, they learned that the attacking systems were typically home routers that had a known vulnerability, named the Misfortune Cookie by Checkpoint Software Technologies. Interestingly, Checkpoint reported the vulnerability in 2005. However, this attack showed that a specific Internet Service Provider (ISP) in Algeria was issuing these unpatched routers to its customers.

Botnet herders sometimes maintain complete control over their botnets. Other times, they rent access out to others to use as desired. Some of the instructions sent by the command-and- control servers include:
• Send spam.
• Launch a distributed denial-of-service attack.
• Download additional malware, adware, or spyware such as keyloggers.

Rootkits

A rootkit is a group of programs (or, in rare instances, a single program) that hides the fact that the system has been infected or compromised by malicious code. A user might suspect something is wrong, but antivirus scans and other checks indicate everything is fine because the rootkit hides its running processes to avoid detection.

In addition to modifying the internal operating system processes, rootkits often modify system files such as the Registry. In some cases, the rootkit modifies system access, such as removing users’ administrative access.

Rootkits have system-level access to systems. This is sometimes called root-level access, or kernel-level access, indicating that they have the same level of access as the operating system. Rootkits use hooked processes, or hooking techniques, to intercept calls to the operating system. In this context, hooking refers to intercepting system-level function calls, events, or messages. The rootkit installs the hooks into memory and uses them to control the system’s behavior.

Antivirus software often makes calls to the operating system that could detect malware, but the rootkit prevents the antivirus software from making these calls. This is why antivirus software will sometimes report everything is OK, even if the system is infected with a rootkit. However, antivirus software can often detect the hooked processes by examining the contents of the system’s random access memory (RAM).

Another method used to detect rootkits is to boot into safe mode, or have the system scanned before it boots, but this isn’t always successful. It’s important to remember that rootkits are very difficult to detect because they can hide so much of their activity. A clean bill of health by a malware scanner may not be valid.

It’s important to remember that behind any type of malware, you’ll likely find an attacker involved in criminal activity. Attackers who have successfully installed a rootkit on a user’s system might log on to the user’s computer remotely, using a backdoor installed by the rootkit. Similarly, attackers might direct the computer to connect to computers on the Internet and send data. Data can include anything collected from a keylogger, collected passwords, or specific files or file types stored on the user’s computer.

Q. A security administrator recently noticed abnormal activity on a workstation. It is connecting to systems outside the organization’s internal network using uncommon ports. The administrator discovered the computer is also running several hidden processes. Which of the following choices BEST describes this activity?

A. Rootkit

B. Backdoor

C. Spam

D. Trojan

Answer is A. A rootkit typically runs processes that are hidden and it also attempts to connect to computers via the Internet.

Although an attacker might have used a backdoor to gain access to the user’s computer and install the rootkit, backdoors don’t run hidden processes.

Spam is unwanted email and is unrelated to this question.

A Trojan is malware that looks like it’s beneficial, but is malicious.

See Chapter 6 of the CompTIA Security+: Get Certified Get Ahead: SY0-501 Study Guide for more information on malware types.

Understanding New Threats

If you’re planning to take the SY0-501 version of the Security+ exam, you should understand new threats and new security trends. The single best protection against many attacks, such as social engineering, is to train and raise the security awareness of users.

For example, can you answer this question?

Q. Your organization recently suffered a loss from malware that wasn’t previously known by any trusted sources. Which of the following BEST describes this attack?

A. Phishing

B. Zero-day

C. Open-source intelligence

D. Hoax

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.

Untrained users provide a significant risk to any organization and are often one of the largest vulnerabilities. They don’t need to be malicious insiders. They can simply be unaware of the risks. Think back to the Fancy Bear and Cozy Bear APT attacks mentioned in this chapter. No matter how much money an organization is spending on technology, it can all be bypassed by a single user clicking on a malicious link in an email. The impact can be the infection of an entire network.

The single best protection against many attacks, such as social engineering and phishing attacks, is to train and raise the security awareness of users. Many users simply aren’t aware of the attackers’ methods. However, once they understand the risks and methods used by social engineers and other attackers, they are less likely to fall prey to these attacks. Similarly, raising users’ security awareness helps them recognize and respond appropriately to new threats and security trends.

Security-related awareness and training programs take many forms. Some common methods include formal classes, short informal live training sessions, online courses, posters, newsletters, logon banners, and periodic emails. These programs often keep users aware of new threats and new security trends and alerts, such as new malware, current phishing attacks, and zero-day exploits.

Understanding New Threats

New Viruses

Criminals are constantly releasing new viruses and some prove to be exceptionally damaging. Many of these require administrators to take quick action to mitigate the threat. For example, when vendors discover a vulnerability that attackers can exploit, they release patches and updates to remove the vulnerability. Administrators then need to evaluate, test, and implement the patches or upgrades to servers. Similarly, home users should keep their systems and applications up to date.

Kindle edition also available.

Phishing Attacks

In addition to releasing new viruses regularly, criminals are also launching new phishing attacks. Some new attempts are tricky and fool many people. The best way to prevent successful attacks is to educate people about what the criminals are doing now.

As an example, criminals crafted a sophisticated attack on Gmail users that fooled even tech-savvy users. Once they had captured the Gmail credentials of one user, they quickly logged on to that user’s account and scoured it for sent emails, attachments, and subject lines.

They then used this account to send emails to people this person previously emailed, often using similar subject lines. Additionally, they often include what looks like a thumbnail of a document. Typically, clicking the thumbnail provides a preview of the document. However, this instead opened up another tab within the browser with a URL like this: data:text/html,https://accounts.google.com/ServiceLogin?service=mail…

When users see accounts.google.com, it looks legitimate. Additionally, the page shows a sign-in page that looks exactly like the Google sign-in page. It isn’t, though. Users who were tricked into “logging on” on this bogus but perfectly created web page were compromised. Attackers quickly logged on to this account and started the process all over again, hoping to snare other unsuspecting users.

In one publicized example, the attackers used a compromised account to resend a team practice schedule to all the members of the team. It included a similar subject line and screenshot of the original attachment. Some recipients who received the email clicked the thumbnail and were taken to the same URL with accounts.google.com in it. Some were tricked and entered their credentials to apparently log on to Google. Attackers quickly logged on to the newly compromised accounts and started the process again.

Zero-Day Exploits

As a reminder, a zero-day vulnerability is a vulnerability or bug that is unknown to trusted sources, such as operating system and antivirus vendors. Operating system vendors write and release patches once they know about them, but until the vendors know about them, the vulnerability remains. As an example, the Heartbleed vulnerability existed for a couple of years before it was widely published. Up until the time that OpenSSL developers released a fix, everyone using it was vulnerable.

Users might adopt the idea that up-to-date antivirus software will protect them from all malware. This simply isn’t true. No matter how great an antivirus company is at identifying new malware, there is always going to be a lag between the time when criminals release the malware and the antivirus company releases new signatures to discover it. This is especially true when attackers are releasing more than 200,000 new variants of malware daily. This includes malware designed to take advantage of zero-day vulnerabilities.

Q. Your organization recently suffered a loss from malware that wasn’t previously known by any trusted sources. Which of the following BEST describes this attack?

A. Phishing

B. Zero-day

C. Open-source intelligence

D. Hoax

Answer is B. A zero-day exploit is one that isn’t known by trusted sources such as antivirus vendors or operating system vendors.

Phishing is malicious spam and it can include malware, but there isn’t an indication this loss was from an email.

Attackers use open-source intelligence to identify a target. Some typical sources are social media sites and news outlets.

A hoax is not a specific attack. It is a message, often circulated through email, that tells of impending doom from a virus or other security threat that simply doesn’t exist.

See Chapter 6 of the CompTIA Security+: Get Certified Get Ahead: SY0-501 Study Guide for more information on threats, vulnerabilities, and common attacks.

Personnel Security Awareness

Personnel security awareness training helps mitigate risk and reduce security incidents. If you’re planning to take the SY0-501 version of the Security+ exam, you should understand the importance of training related to organizational security.

See if you can answer this question?

Q. Social engineers have launched several successful phone-based attacks against your organization resulting in several data leaks. Which of the following would be MOST effective at reducing the success of these attacks?

A. Implement a BYOD policy.

B. Update the AUP.

C. Provide training on data handling.

D. Implement a program to increase security awareness.

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.

Role-Based Awareness Training

Role-based awareness training is targeted to personnel based on their roles. The primary goal is to minimize the risk to the organization, and by giving users the training they need, they are better prepared to avoid threats.

The following roles often require role-based training:
Data owner. Data owners need to understand their responsibilities related to data that they own. This includes ensuring that the data is classified correctly and ensuring that the data is labeled to match the classification. They are also responsible for ensuring adequate security controls are implemented to protect the data. While they often delegate day-to-day tasks to data custodians, they cannot delegate their responsibility.
System administrator. System administrators are responsible for the overall security of a system. They often need technical training so that they understand the software capabilities and vulnerabilities, and how to ensure the system is operating in a secure state. As a simple example, if an organization purchases a new hardware firewall, system administrators need training to ensure they know how to implement it securely.
System owner. A system owner is typically a high-level executive or department head who has overall responsibility for the system. While system owners won’t perform daily maintenance on their systems, they are responsible for ensuring that system administrators have the skills and knowledge to maintain them.
Personnel Security AwarenessUser. Regular end users need to understand common threats, such as malware and phishing attacks. They also need to understand the risk posed by clicking an unknown link and how drive-by downloads can infect their system. Training can include a wide variety of topics depending on the organization and can be delivered via different methods. For example, security experts can send emails informing users of current threats. Some training is delivered via web sites, in a classroom, or informally by supervisors. Training is often included when users review and sign an organization’s AUP.
Privileged user. A privileged user is any user with more rights and permissions than typical end users. Privileged users need training on the classification and labeling of data that they handle. Administrators are often required to use two accounts, one for regular use and one for administrative use. For administrators to follow this policy, they need to understand why it’s implemented and the potential repercussions if the administrator always uses the administrator account.
Executive user. Executives need high-level briefings related to the risks that the organization faces, along with information on the organization’s overall information security awareness program. Additionally, executives should be trained on whaling attacks because attackers target executives with malicious phishing emails.
Incident response team. An incident response team needs detailed training on how to respond to incidents. Even within the team, personnel might require different training. For example, security personnel responsible for forensic investigations need specialized forensic training.

The success of any security awareness and training plan is directly related to the support from senior management. If senior management supports the plan, middle management and employees will also support it. On the other hand, if senior management does not show support for the plan, it’s very likely that personnel within the organization will not support it either.

Continuing Education

Training is rarely a once and done event. Instead, personnel need to regularly receive additional training to ensure they are up to date on current threats, vulnerabilities, and technologies. If network administrators are still using the same practices and technologies they learned 10 years ago, their networks are very likely vulnerable to a multitude of attacks.

This concept is used in many different professions. For example, your doctor is required to regularly attend continuing education to update her knowledge. That’s a good thing. When you’re receiving medical treatment and advice, you don’t want treatment and advice that was valid a decade ago, but might not be valid today. Similarly, many certifications (including the CompTIA Security+ certification) have formal continuing education requirements.

Continuing education within an organization can take many forms. It’s often possible to send personnel to classes to update their knowledge. When many people need the same training, an organization will often bring in a trainer to teach a class in-house.

Q. Social engineers have launched several successful phone-based attacks against your organization resulting in several data leaks. Which of the following would be MOST effective at reducing the success of these attacks?

A. Implement a BYOD policy.

B. Update the AUP.

C. Provide training on data handling.

D. Implement a program to increase security awareness.

Answer is D. The best choice of the available answers is to implement a program to increase security awareness, and it could focus on social engineering attacks.

A bring your own device (BYOD) policy or an acceptable use policy (AUP) doesn’t apply in this scenario.

Training is useful, but training users on data handling won’t necessarily educate them on social engineering attacks.

Identifying Critical Systems

If you’re planning to take the SY0-501 version of the Security+ exam, you should understand business impact analysis concepts. It helps an organization identify critical systems and components that are essential to the organization’s success.

For example, can you answer this Security+ question?

Q. Lisa is the new chief technology officer (CTO) at your organization. She wants to ensure that critical business systems are protected from isolated outages. Which of the following would let her know how often these systems will experience outages?

A. MTTR

B. MTBF

C. RTO

D. RPO

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.

Impact

The business impact analysis (BIA) evaluates various scenarios, such as fires, attacks, power outages, data loss, hardware and software failures, and natural disasters. Additionally, the BIA attempts to identify the impact from these scenarios.

When evaluating the impact, a BIA looks at multiple items.  For example, a database server might host customer data, including credit card information. If an attacker was able to access this customer data, the cost to the organization might exceed millions of dollars.

You might remember the attack on retail giant Target during November and December 2013. Attackers accessed customer data on more than 110 million customers, resulting in significant losses for Target. Estimates of the total cost of the incident have ranged from $600 million to over $1 billion. This includes loss of sales—Target suffered a 46 percent drop in profits during the last quarter of 2013, compared with the previous year. Customers were afraid to use their credit cards at Target and simply stayed away. It also includes the cost to repair their image, the cost of purchasing credit monitoring for affected customers, fines from the payment-card industry, and an untold number of lawsuits. Target reportedly has $100 million in cyber insurance that helped them pay claims related to the data breach.

Identifying Critical Systems

Recovery Time Objective

The recovery time objective (RTO) identifies the maximum amount of time it can take to restore a system after an outage. Many BIAs identify the maximum acceptable outage or maximum tolerable outage time for mission-essential functions and critical systems. If an outage lasts longer than this maximum time, the impact is unacceptable to the organization.

For example, imagine an organization that sells products via a web site generates $10,000 in revenue an hour. It might decide that the maximum acceptable outage for the web server is five minutes. This results in an RTO of five minutes, indicating any outage must be limited to less than five minutes. This RTO of five minutes only applies to the mission-essential function of online sales and the critical systems supporting it.

Imagine that the organization has a database server only used by internal employees, not online sales. Although the database server may be valuable, it is not critical. Management might decide they can accept an outage for as long as 24 hours, resulting in an RTO of less than 24 hours.

A recovery point objective (RPO) identifies a point in time where data loss is acceptable. As an example, a server may host archived data that has very few changes on a weekly basis. Management might decide that some data loss is acceptable, but they always want to be able to recover data from at least the previous week. In this case, the RPO is one week.

With an RPO of one week, administrators would ensure that they have at least weekly backups. In the event of a failure, they will be able to restore recent backups and meet the RPO.

In some cases, the RPO is up to the minute of the failure. For example, any data loss from an online database recording customer transactions might be unacceptable. In this case, the organization can use a variety of techniques to ensure administrators can restore data up to the moment of failure.

Comparing MTBF and MTTR

When working with a BIA, experts often attempt to predict the possibility of a failure.

For example, what is the likelihood that a hard disk within a RAID configuration will fail? The following two terms are often used to predict potential failures:
Mean time between failures (MTBF). The mean time between failures (MTBF) provides a measure of a system’s reliability and is usually represented in hours. More specifically, the MTBF identifies the average (the arithmetic mean) time between failures. Higher MTBF numbers indicate a higher reliability of a product or system. Administrators and security experts attempt to identify the MTBF for critical systems with a goal of predicting potential outages.
Mean time to recover (MTTR). The mean time to recover (MTTR) identifies the average (the arithmetic mean) time it takes to restore a failed system. In some cases, people interpret MTTR as the mean time to repair, and both mean essentially the same thing. Organizations that have maintenance contracts often specify the MTTR as a part of the contract. The supplier agrees that it will, on average, restore a failed system within the MTTR time. The MTTR does not provide a guarantee that it will restore the system within the MTTR every time. Sometimes, it might take a little longer and sometimes it might be a little quicker, with the average defined by the MTTR.

Q. Lisa is the new chief technology officer (CTO) at your organization. She wants to ensure that critical business systems are protected from isolated outages. Which of the following would let her know how often these systems will experience outages?

A. MTTR

B. MTBF

C. RTO

D. RPO

Answer is B. The mean time between failures (MTBF) provides a measure of a system’s reliability and would provide an estimate of how often the systems will experience outages.

The mean time to recover (MTTR) refers to the time it takes to restore a system, not the time between failures.

The recovery time objective (RTO) identifies the maximum amount of time it can take to restore a system after an outage.

The recovery point objective (RPO) identifies a point in time where data loss is acceptable.
