Identifying Physical Security Access Controls

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

For example, can you answer this practice test question?

Q. Thieves recently rammed a truck through the entrance of your company’s main building. During the chaos, their partners proceeded to steal a significant amount of IT equipment. Which of the following choices can you use to prevent this from happening again?

A. Bollards

B. Guards

C. CCTV

D. Mantrap

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.

Securing Access with Barricades

In some situations, fencing isn’t enough to deter potential attackers. To augment fences and other physical security measures, organizations erect stronger barricades. As an example, military bases often erect strong, zigzag barricades that require vehicles to slow down to navigate through them. This prevents attackers from trying to ram through the gates.

Businesses and organizations need to present an inviting appearance, so they can’t use such drastic barricades. However, they often use bollards, which are short vertical posts, composed of reinforced concrete and/or steel. They often place the bollards in front of entrances about three or four feet apart. They typically paint them with colors that match their store. You’ve probably walked through a set of bollards multiple times without giving them a second thought. However, thieves who are contemplating driving a car or truck through the entrance see them.

Many thieves have driven vehicles right through the front of buildings, and then proceeded to steal everything in sight. Depending on the strength of the walls, criminals might even be able to drive through a wall with a truck. Strategically placed bollards will prevent these types of attacks.

Preventing Tailgating with Mantraps

A mantrap is a physical security mechanism designed to control access to a secure area through a buffer zone. Personnel use something like a proximity card to gain access, and the mantrap allows one person, and only one person, to pass through. Because they only allow one person through at a time, mantraps prevent tailgating. Mantraps get their name due to their ability to lock a person between two areas, such as an open access area and a secure access area, but not all of them are that sophisticated.

An example of a simple mantrap is a turnstile similar to what you see in many public transport systems. Even if you’ve never ridden the subway in one of many U.S. cities or the Tube in London, you’ve probably seen turnstiles in movies such as While You Were Sleeping. When customers present a token, the turnstile unlocks and allows a single person through at a time. Similarly, users unlock the turnstile mantrap with something like a proximity card.

A sophisticated mantrap is a room, or even a building, that creates a large buffer area between the secure area and the unsecured area. Access through the entry door and the exit door is tightly controlled, either with guards or with an access card such as a proximity card.

It’s also possible to require identification and authentication before allowing passage through a mantrap. For example, a retina scanner can identify individuals and restrict access   to only authorized individuals. Similarly, some card reader systems support the use of unique PINs assigned to the user. Users present their card and enter their PIN to gain access before the mantrap opens.

Monitoring Areas with Cameras

Organizations are increasingly using security cameras in the workplace and surrounding areas for video surveillance. This includes areas outside of a building, such as a parking lot, and all building entrances and exits. Additionally, many organizations use cameras to monitor internal entrances of high-security areas, such as the entrance of a data center or server room.

Cameras are connected to a closed-circuit television (CCTV) system, which transmits signals from video cameras to monitors that are similar to TVs. In addition to providing security, CCTV can also enhance safety by deterring threats.

Organizations often use video cameras within a work environment to protect employees and enhance security in the workplace. In addition to live monitoring, most systems include a recording element, and they can verify if someone is stealing the company’s assets. By recording activity, videos can be played back later for investigation and even prosecution.

Identifying Physical Security Access Controls

Video surveillance provides the most reliable proof of a person’s location and activity. Access logs provide a record, but it’s possible to circumvent the security of an access log. For example, if Bart used your proximity card to gain access to a secure space, the log will indicate you entered, not Bart. In contrast, if the video shows that Bart entered the room at a certain time of day, it’s not easy for Bart to refute the video.

When using video surveillance in a work environment, it’s important to respect privacy and to be aware of privacy laws. Some things to consider are:

  • Only record activity in public areas. People have a reasonable expectation of privacy in certain areas, such as locker rooms and restrooms, and it is often illegal to record activity in these
  • Notify employees of the surveillance. If employees aren’t notified of the surveillance, legal issues related to the video surveillance can arise. This is especially true if the recordings are used when taking legal and/or disciplinary actions against an
  • Do not record audio. Recording audio is illegal in many jurisdictions, without the express consent of all parties being recorded. Many companies won’t even sell surveillance cameras that record audio.

Q. Thieves recently rammed a truck through the entrance of your company’s main building. During the chaos, their partners proceeded to steal a significant amount of IT equipment. Which of the following choices can you use to prevent this from happening again?

A. Bollards

B. Guards

C. CCTV

D. Mantrap

Answer is A. Bollards are effective barricades that can block vehicles.

Guards can restrict access for personnel, but they cannot stop trucks from ramming through a building.

Closed-circuit television (CCTV) or a similar video surveillance system can monitor the entrance, but it won’t stop the attack.

Mantraps prevent tailgating, but they most likely won’t stop a truck.

Schmucks Still Scamming and Stealing

The IRS* called me recently and left a message on my phone.

Apparently, they issued a warrant for my arrest and plan to notify the local police to find and arrest me if I don’t pay them an unspecified sum. They asked me to call them immediately to avoid these actions.

Gratefully, I recognized this as a long-running scam. The Federal Trade Commission (FTC) points out a few facts about the IRS.

  • If the IRS needs to contact you, they’ll do it by mail first.
  • The IRS won’t demand personal information like credit card or Social Security numbers over the phone.
  • The IRS won’t threaten to arrest or sue you, or demand that you pay right away. The IRS also won’t tell you to use a specific form of payment like a money transfer from MoneyGram or Western Union, a cash reload from MoneyPak or Reloadit, or a gift card from iTunes or Amazon. Scammers ask you to use those ways to pay because they’re hard to track or cancel payments.

If you’re aware of cybersecurity techniques used by criminals, this may not be news to you. However, this scam frequently targets the elderly and people who don’t work with computers much. Share this information with them so that won’t be fooled.

* The Internal Revenue Service (IRS) doesn’t call you.

Holiday Scams and Malware Campaigns

Of course, criminals don’t just use the phone to trick users. Here’s some valuable information shared by US-CERT:

As the holidays approach, the Cybersecurity and Infrastructure Security Agency (CISA) reminds users to be aware of seasonal scams and malware campaigns. Users should be cautious of unsolicited emails that contain malicious links or attachments with malware, advertisements infected with malware, and requests for donations from fraudulent charitable organizations, which could result in security breaches, identify theft, or financial loss.

CISA recommends the following actions:

If you believe you are a victim of a scam or malware campaign, consider the following actions:

Organizational Security Policies

Written security policies are administrative controls that identify a security plan. If you’re planning to take the Security+ SY0-501 exam, you should have good understanding of the importance of policies, plans and procedures related to organizational security. Personnel create plans and procedures to implement security controls and enforce the security policies.

For example, can you answer this practice test question?

Q. Dan has been working at your company as an accountant. However, after a disagreement with an executive, he decides to leave the company and work at the local mall. He has a user account allowing him to access network resources. Which of the following is the MOST appropriate step to take?

A. Ensure his account is disabled when he announces that he will be leaving the company.

B. Immediately terminate his employment.

C. Force him to take a mandatory vacation.

D. Ensure his account is disabled during his exit interview.

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.
Organizational Security Policies

NDA

A non-disclosure agreement (NDA) is used between two entities to ensure that proprietary data is not disclosed to unauthorized entities. For example, imagine BizzFad wants to collaborate with Costington’s on a project. BizzFad management realizes they need to share proprietary data with Costington’s personnel, but they want to ensure that distribution of the data is limited.  The NDA is a legal document that BizzFad can use to hold Costington’s legally responsible if the proprietary data is shared.

Similarly, many organizations use an NDA to prohibit employees from sharing proprietary data either while they are employed, or after they leave the organization. It’s common to remind employees of an existing NDA during an exit interview.

Exit Interview

An exit interview is conducted with departing employees just before they leave an organization. Note that an exit interview isn’t only conducted when employees are fired from their job. They are also done when employees leave voluntarily. The overall purpose is for the employer to gain information from the departing employee. Some common questions asked during an exit interview are:

  • What did you like most (and/or least) about your job here?
  • Do you think you had adequate training to do your job here?
  • Can you tell me what prompted you to leave your current position?
  • Can you describe the working relationship you had with your supervisor(s)?
  • What skills and qualification does your replacement need to excel in this position?

Exit interviews are commonly conducted by an employee in the Human Resources (HR) department. In addition to seeking feedback from the employee, departing employees are sometimes required to sign paperwork, such as a reminder about a previously signed NDA. The NDA prevents the employee from sharing proprietary information with personnel outside the organization.

Kindle edition also available.

From a security perspective, it’s also important to ensure other things occur during or before the exit interview. For example, the user’s account should be disabled (or deleted depending on company policy). Ideally, this should occur during the interview. One way organizations do this is by informing the IT department of the time of the scheduled interview   a day before. An administrator then disables the account after the interview starts. The key is that a departing employee should not have access to computing and network resources after the interview.

It’s also important to collect any equipment (such as smartphones, tablets, or laptops), security badges, or proximity cards the organization issued to the employee. This is more than just a cost issue. Equipment very likely has proprietary data on it and the company needs to take steps to protect the data. Additionally, smart cards and proximity cards can allow individuals access to protected areas.

Onboarding

Onboarding is the process of granting individuals access to an organization’s computing resources after being hired. This includes providing the employee with a user account and granting access to appropriate resources. One of the key considerations during the onboarding process is to follow the principle of least privilege. Grant the new employees access to what they need for their job, but no more.

Offboarding is the process of removing their access. When employees leave the company, it’s important to revoke their access. This is often done during the exit interview.

Policy Violations and Adverse Actions

What do you do if an employee doesn’t follow the security policy? What adverse actions should a supervisor take? Obviously, that depends on the severity of the policy violation.

Imagine that an employee sends out an email to everyone in the organization inviting them to his church. The supervisor might decide to verbally counsel the employee and make it clear that sending out personal emails like this is unacceptable. Based on how well the conversation goes, the supervisor might choose to document this as written counseling and place the warning in the employee’s HR folder.

Some incidents require more severe responses. Imagine that an employee begins a cyberbullying campaign against another employee. He has been sending her hateful emails and posting hateful messages on social media pages. In most organizations, this bully will be looking for employment elsewhere once his activity is discovered.

Although it’s possible to document specific adverse actions within a security policy, this is rarely recommended. Actual policy violations aren’t always the same and if the policy requires a specific action in response to a policy violation, it doesn’t always allow supervisors or managers to respond appropriately to a violation.


 

Q. Dan has been working at your company as an accountant. However, after a disagreement with an executive, he decides to leave the company and work at the local mall. He has a user account allowing him to access network resources. Which of the following is the MOST appropriate step to take?

A. Ensure his account is disabled when he announces that he will be leaving the company.

B. Immediately terminate his employment.

C. Force him to take a mandatory vacation.

D. Ensure his account is disabled during his exit interview.

Answer is D. His account should be disabled (or deleted if that is the company policy) during the exit interview. It’s appropriate to conduct an exit interview immediately before an employee departs.

Employees often give a two-week or longer notice. If their access is revoked immediately, they won’t be able to do any more work.

While some companies do terminate employment when someone gives notice, from a security perspective, it’s best to take action related to the user account.

The purpose of a mandatory vacation is to detect fraud, but if the employee is leaving, any potential fraud will be detected when that employee leaves.

SSL/TLS Accelerators

SSL/TLS accelerators refer to hardware devices focused on handling Transport Layer Security (TLS) traffic. TLS is the designated replacement for Secure Sockets Layer (SSL), but many people are familiar with SSL terminology so you’ll continue to see it, even if the only protocol it’s using is TLS.

TLS provides encryption for many different protocols, including Hypertext Transfer Protocol Secure (HTTPS). HTTPS uses a certificate and asymmetric encryption. The process of establishing the HTTPS session, negotiating the best security supported by both the client and the server, sharing encryption keys, and encrypting session data all take a lot of time and resources. By off-loading this to another hardware device, it frees up the primary computer’s resources, such as CPU power and RAM.

When using an SSL accelerator, it’s best to place it as close as possible to related devices. For example, if you’re using an SSL accelerator to off-load HTTPS sessions for a web server, place the SSL accelerator close to the web server.

Understanding Advanced Security Devices

SSL Decryptors

Some organizations use SSL decryptors to combat many threats. For example, attackers are often using encryption to prevent inspection methods from detecting malware coming into a network.

As an example, imagine Homer innocently goes to a malicious web site. The web site establishes a secure HTTPS connection, and then downloads malware to Homer’s computer. Because the site is using HTTPS, the malware is encrypted while in transit. Even if an organization had the best content inspection methods and malware detection software, it wouldn’t detect the malware while it’s encrypted.

An SSL decryptor solves this problem. You would place it in the DMZ, and redirect all traffic to and from the Internet through it. Unencrypted data goes through the device without any modification. However, any attempts to establish an encrypted session prompt the SSL decryptor to create a separate SSL (or TLS) session.

When Homer innocently goes to a malicious web site, the traffic goes though the SSL decryptor. The SSL decryptor establishes an HTTPS session between it and Homer’s computer. It also establishes an HTTPS session between it and the web site. All data-in-transit is encrypted. However, the SSL decryptor can view the unencrypted data and inspect it.

SSL decryptors are often used with a NIPS. The NIPS is inline but malicious traffic can get through if it’s encrypted. The SSL decryptor allows the NIPS to inspect unencrypted traffic and prevent attacks.

Honeypots

A honeypot is a sweet-looking server—at least it’s intended to look sweet to the attacker, similar to how honey looks sweet to a bear. It’s a server that is left open or appears to have been sloppily locked down, allowing an attacker relatively easy access. The intent is for the server to look like an easy target so that the attacker spends his time in the honeypot instead of in a live network. In short, the honeypot diverts the attacker away from the live network.

As an example, a honeypot could be a web server designed to look like a live web server. It would have bogus data such as files and folders containing fabricated credit card transaction data. If an organization suspects it has a problem with a malicious insider, it can create an internal honeypot with bogus information on proprietary projects.

Honeypots typically have minimal protection that an attacker can easily bypass. If administrators don’t use any security, the honeypot might look suspicious to experienced attackers and they might simply avoid it.

Security personnel often use honeypots as a tool to gather intelligence on the attacker. Attackers are constantly modifying their methods to take advantage of different types of attacks. Some sophisticated attackers discover vulnerabilities before a patch is released (also known as a zero-day exploit, or zero-day vulnerability). In some cases, security professionals observe attackers launching zero-day vulnerability attacks against a honeypot.

Honeypots never hold any data that is valuable to the organization. The data may appear to be valuable to an attacker, but its disclosure is harmless. Honeypots have two primary goals:

  • Divert attackers from the live network. If an attacker is spending time in the honeypot, he is not attacking live resources.
  • Allow observation of an attacker. While an attacker is in the honeypot, security professionals can observe the attack and learn from the attacker’s methodologies. Honeypots can also help security professionals learn about zero-day exploits, or previously unknown attacks.

 

Q. Of the following choices, what can you use to divert malicious attacks on your network away from valuable data to worthless, fabricated data?

A. IPS

B. Proxy server

C. Web application firewall

D. Honeypot

Answer is D. A honeypot can divert malicious attacks to a harmless area of your network, such as away from production servers holding valid data.

An intrusion prevention system (IPS) can block attacks, but it doesn’t divert them.

A proxy server can filter and cache content from web pages, but it doesn’t divert attacks.

Using Security Tools

Several security tools are available for use by security professionals and attackers alike. If you’re planning to take the Security+ SY0-501 exam, you should have basic understanding of using appropriate software tools to assess the security posture of an organization such as using command line tools.

For example, can you answer this practice test question?

Q. You suspect that an attacker has been sending specially crafted TCP packets to a server trying to exploit a vulnerability. You decide to capture TCP packets being sent to this server for later analysis and you want to use a command-line tool to do so. Which of the following tools will BEST meet your need?

A. Wiredump

B. Tcpdump

C. Netcat

D. Nmap

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.

Some tools are useful when performing vulnerability scans and penetration tests. Three tools discussed in this post are tcpdump, Nmap, and Netcat.

Using Security Tools

Tcpdump

Tcpdump is a command-line packet analyzer (or protocol analyzer). It allows you to capture packets like you can with Wireshark. The difference is that Wireshark is a Windows-based tool and tcpdump is executed from the command line. Many administrators use tcpdump to capture the packets and later use Wireshark to analyze the packet capture.

Kali Linux includes tcpdump, but you won’t find it on Windows systems. As with most Linux command-line tools, tcpdump is case sensitive. You need to enter tcpdump in all lowercase. Additionally, the switches must be entered with the proper case. For example, -c (lowercase c) represents count and indicates the capture should stop after receiving the specified number of packets. However, -C (uppercase C) represents file size and indicates the maximum size (in millions of bytes) of a packet capture. When the file reaches this size, tcpdump closes it and starts storing packets in a new file.

Nmap

Nmap is a network scanner. The graphical side of Nmap is Zenmap.

It includes many capabilities, including identifying all the active hosts and their IP addresses in a network, the protocols and services running on each of these hosts, and the operating system of the host. When running the command, you include the scan type(s), optional options, and target specifications. As an example, consider the following command:

nmap -T4 -A -v 192.168.0.0/24

Notice that it has three switches, -T4, -A, and -v:

  • T4. T4 refers to the speed of the scan. Valid switches are T0 through T5 with T0 being the slowest and T5 being the fastest. Faster scans are likely to be detected, while slower scans may not be detected.
  • A. The -A switch indicates the scan should include OS detection, version detection, script scanning, and traceroute.
  • -v. The -v switch indicates the verbosity You can get more data output by using -vv or -vvv.

Netcat

Administrators often use Netcat for remotely accessing Linux systems. It doesn’t include native encryption so it’s common to use SSH to secure the session. Also, Netcat can easily be used for banner grabbing. The following is a sample command used for banner grabbing:

echo “” | nc -vv -n -w1 72.52.206.134 80

It uses the netcat command (nc) along with some switches: -vv for a verbose output, -n to not resolve host names, -w1 to wait no more than 1 second for a reply. The command connects to port 80 of the system with an IP address of 72.52.206.134. The echo “” sends a blank command to the server and the pipe symbol ( | ) tells Netcat to send the command after establishing the connection.

Some other uses of Netcat include:

  • Transferring files. One of the online labs for Chapter 3 shows how to create a chat session between two Once this session is open, you can use the connection to copy files between the systems.
  • Port scanner. You can use Netcat to run a port scan against a single IP address. It allows you to specify the range of ports, such as 10 through 1024 and randomize the ports scanned to evade detection. It also supports waiting longer periods of time between port checks, again, to evade detection.

Remember this

Tcpdump is a command-line protocol analyzer. It can create packet captures that can then be viewed in Wireshark. Nmap is a sophisticated network scanner that runs from the command line. Netcat can be used to remotely administer systems and also gather information on remote systems.

Q. You suspect that an attacker has been sending specially crafted TCP packets to a server trying to exploit a vulnerability. You decide to capture TCP packets being sent to this server for later analysis and you want to use a command-line tool to do so. Which of the following tools will BEST meet your need?

A. Wiredump

B. Tcpdump

C. Netcat

D. Nmap

Answer is B. The tcpdump command-line tool is the best choice of the given answers. It is a command- line packet analyzer (or protocol analyzer) and its primary purpose is to capture packets.

Wiredump isn’t a valid tool name. Wireshark (not included as an answer choice) is a graphic-based packet analyzer that can be started from the command line, but tcpdump includes more command-line options than Wireshark.

Netcat is useful for remotely accessing systems and can be used for banner grabbing, but it doesn’t capture packets.

Nmap analyzes packets during a scan. It can also use Npcap, the Nmap Project’s packet sniffing library, but Nmap isn’t the best choice to capture packets.

Early Detection Saves Lives

Chances are that you know someone that has breast cancer. Even if you and the other person don’t know it.

However, in this case ignorance is not bliss. What you and others don’t know can kill.

About six months ago, I knew someone that had breast cancer – Nimfa, my wife of 26 years. However, neither she nor I knew she had it.

Some time later a “routine” mammogram discovered an abnormality and a doctor ordered a biopsy. The biopsy was negative indicating no problem, but the experienced breast cancer doctor refused to believe it. He ordered another one and this one came back positive. Nimfa was now diagnosed with breast cancer.

Gratefully, the lump wasn’t large, the cancer type isn’t overly aggressive, and we have overall great healthcare.

Here’s something that women typically know, but men rarely do. A “routine” mammogram isn’t always routine for the women experiencing it. My wife has told me about how some techs roughly pull, tug, press, and compress the breasts to get them into the right position. It’s as if the tech forgets that there is a person attached to the breasts.

Of course, all the techs weren’t so rough, but because of some bad experiences, Nimfa was less than enthusiastic about going through this annually. However her healthcare team gave her regular reminders and she followed their advice.

Some medical organizations such as the Mayo Clinic recommend annual mammograms for women over 40, but there are other recommendations.

Surgery and Sentinel Nodes

Nimfa chose a lumpectomy to remove the lump. Based on the severity and other factors, some women choose a mastectomy to remove their entire breast.

During the surgery, the doctor removed the lump and surrounding tissues. He also removed two sentinel lymph nodes for testing.

I think of the sentinel nodes as guards on the body’s primary highway leaving the breast and going to the rest of the body. If cancer spreads beyond the lump it must first pass through these guards and testing will show that these guards (the sentinel nodes) have been attacked. This helps doctors determine the best follow-on treatment.

Unfortunately, a technician in the lab destroyed these sentinel nodes instead of putting them through the testing process.

Oncotype DX Test

Medical technologies continue to advance by leaps and bounds. The Oncotype DX test can be done on the removed breast tissue and is appropriate in some situations. Nimfa’s surgeon ordered it for her.

It analyzes 21 genes and comes back with a score indicating the likelihood of breast cancer recurrence. This score helps doctors determine if chemotherapy would be beneficial, assuming that other standard therapies are followed.

Some scores make it easy to choose chemotherapy or skip it. For example, a score of 10 indicates the breast cancer is not likely to recur in the next 10 years (and chemotherapy isn’t necessarily warranted). In contrast, a score of 50 indicates a high risk of recurrence in the next 10 years if chemotherapy isn’t pursued. Scores between 18 and 31 indicate an intermediate risk and the choice isn’t so clear.

Nimfa’s score was 26.

Chemotherapy and Med Port

Her doctors quoted a study published in The New England Journal of Medicine in July 2018 that provides a better guideline.  Specifically, it indicated that women with a score of 26 and above were more likely to benefit from chemotherapy.

After more tests and getting more information, Nimfa decided to pursue chemotherapy.

To prepare, she underwent surgery to install a Bard PowerPort device. This is a small device about the size of a thumb. It has an attached catheter that the surgeon threads though a blood vessel into a larger vein. This can be used for repeated injections, without repeated needle sticks into arm or leg veins.

The Road Ahead

Nimfa starts chemotherapy on October 31 and will be receiving periodic treatments followed by recovery periods up until about January 2. We’ve received a lot of information on what might occur, but it includes some unknowns. My intention is simply to be with her as much as she desires.

This will be followed by daily radiation therapy for several weeks and then a pill for hormone therapy for the next five years.

Quick Facts

October is Breast Cancer Awareness month and here are some quick facts I saw on a poster at the hospital.

  • Breast cancer is the second most common cancer diagnosed in women.
  • Every 2 minutes a woman is diagnosed with breast cancer.
  • Every 13 minutes a woman will die from breast cancer.
  • 85% of breast cancer develop in women with no family history
  • Early detection can make the disease easier to treat.

Early Detection Saves Lives

The bottom line is that because this was detected in my wife early, her life is not in danger.

Admittedly, this has caused some stress for me (and her). However, I feel much better about it at this point and wanted to share a simple message with others.

Early detection saves lives.

Unfortunately, because mammograms aren’t always comfortable experiences, some women choose to avoid them. If you have loved ones in your life that are due to get this test, you might like to encourage them to get it.Early Detection Saves Lives
