Information Security Risk Matrix

Every organization is unique, so the risks they each face are not the same. In order to make a plan of action to protect your business, you need to first understand where the threats against you are. Once you know where those risks and gaps are you can start to identify the likelihood of them occurring and the impact they could have on your organization.

This sort of knowledge is crucial when making risk-based decisions for your company. Without full knowledge of where, how, and why a threat could occur, you’re not going to be able to stop it. That’s why understanding likelihood and impact are both important factors in the Risk Assessment process.

Keep it Simple

You don’t have to have a complex formula in order to improve or support the security environment of your organization. However, it is important for leadership to understand where time and resources need to be spent in order to reduce potential risks to the company. That’s how Risk Assessments can shed light on the key factors in this decision-making process.

Having a better understanding of the system also helps out other members of your staff. Members of the IT department need to know what products and processes to put into place in order to limit potential risks. The more knowledge they have, the better they can work with leadership to determine and address security concerns. Sharing the Risk Assessment results with members of the IT team will help them understand where to reduce risks.

Risk Formula

Risk = Threats x Vulnerabilities

This is a common formula that is used to determine the likelihood of risk. It’s a good way to approach finding risk because it addresses the key factors in a cybersecurity threat.

The standard set in NIST 800-53 implies that a realistic assessment of risk requires an understanding of these areas: threats to an organization, potential vulnerabilities within the organization, and the likelihood and impacts of successfully exploiting the vulnerabilities with those threats. That likelihood is then best described and categorized in values of High, Medium, and Low.

Getting Started

Now that you know the importance and formula for determining likelihood and impact during a Risk Assessment, here’s how you get started!

First, determine the inherent risk. That is, the risk level and exposure your system faces without taking into account any mitigating measures or controls that are actively in place. Where is your system at its weakest when no other security measures are in place to protect them?

An area with a higher likelihood and impact of a threat on the organization, from an inherent risk level, may need additional controls to reduce the level of risk to an acceptable level. This process then leaves you with what we call “residual risk”. That’s the level of risk that will remain following the implementation of a mitigating control. If the threshold is still higher than you prefer, then additional risk management measures and techniques should be introduced.

 Mitigating Measures:

  • Avoidance – Elimination of the cause of the risk.
  • Mitigation – Reduction of the probability of a risk’s occurrence or of its impact.
  • Transfer – Sharing of risk with partners, such as through insurance or other ventures.
  • Acceptance – Formal acknowledgement of the presence of risk with a commitment to monitor it.

Finding Help

If you’ve now read through how determining likelihood and impact can help your Risk Assessment process, but still aren’t sure where to go next, there is help available through cybersecurity consultants. These experts in the field can help by looking over a number of key factors you may not have considered.

Cybersecurity Consultants are able to analyze your organization’s structure, policies, standards, technology, architecture, controls, and more to determine the likelihood and impact of potential risks. They will also review your current controls and evaluate their effectiveness.

While determining how secure your network is, Consultants will also assess any gaps between your current security posture and where you want your organization to be. This can be accomplished by determining accountability. That means ensuring risk ownership is assigned at the appropriate level and to the appropriate team. It’s important to have the right security measures in the right hands.

End Goal

The end goal is to get to an acceptable level of risk or the level of risk that is satisfactory to your management team. It’s important to evaluate and be aware of the risk in your environment so you can implement appropriate controls to mitigate this risk and secure sensitive information. Evaluating risk means understanding the biggest factors of any security threat, likelihood and impact.

Risk Assessment Value

Whether you’re a small business trying to figure out where to start with your cybersecurity needs, or you’re a larger corporation wanting to make sure the security measures you put in place are working properly, an Information Security Risk Assessment is a great way to get a thorough look inside your organization.

Taking the time to go over possible threats is crucial in preventing issues down the road and giving your business the best chance at long-term success. Here are the basic steps of a Risk Assessment, and why this process can provide so much value to your cybersecurity program.

What is an Information Security Risk Assessment?

A Risk Assessment helps guide an organization in making rational decisions to improve security posture and align risk with acceptable tolerance levels.

What does that really mean?

Cybersecurity experts, such as Pratum Consultants, conduct a comprehensive overview of your current security measures and come up with a list of possible threats. This is based on the issues your company is likely to face. Not all organizations have the same security threats.

The Risk Assessment process helps IT departments and business owners find and evaluate risk while aligning with business objectives.

Why is it Necessary?

A Risk Assessment offers sort of a window into your organization’s security operations. The process reveals exactly where there are flaws, what’s working well, and what might not be necessary. Being able to have a certified expert go over your security posture can help you better understand things that may have been overlooked in the past.

This kind of knowledge is valuable for preventing security breaches, securing sensitive information, and reassuring clients their own data is being protected.

Not only is this important for the function of your company, information security risk assessments are also the first requirement outlined in federal regulations such as Sarbanes-Oxley Act (SOX), Gramm-Leach Bliley Act (GLBA), and Health Insurance Portability and Accountability Act (HIPAA). The Payment Card Industry – Data Security Standards (PCI-DSS) also require merchants of all sizes to perform due diligence in assessing risk in their technology operations.

How Does the Process Work?

These are a few of the key steps during a Information Security Risk Assessment.

1. Prepare

The first step is to determine why the assessment is needed? You’ll want to figure out the information the assessment is intended to produce and the decisions it is intended to support. Knowing the goal of the process will help direct the steps taken.

You will also select a control framework. Pratum bases risk assessments off a subset of controls from NIST 800-53. Other highly regarded frameworks are the Center for Information Security (CIS) Top 20 and NIST 800-171.

2. Conduct

The objective of this step is to create a list of information security threats that can be prioritized by risk level and used to inform risk response decisions. That includes identifying any threat sources, risks, and vulnerabilities. Then the risk levels and likelihood are analyzed.

This step also includes interviews with department managers and key business personnel. The focus is on how sensitive information flows through the systems and/or applications they manage.

Here are some questions that may come up:

  • Are there any concerns with data flow models?
  • Does the information have the potential to be seen by unauthorized individuals?
  • Are there vulnerabilities within these systems that could lead to device compromise?
  • Does management have adequate visibility into the risk management program?

While risk assessments can be conducted internally, it is helpful to bring in a third party to have an independent set of eyes evaluate IT environments.

3. Review

The last step involves reviewing IT controls and using control frameworks as a guide to implement these controls in a secure manner. This is followed by communicating the information discovered and finding out how decision makers within the organization can use the information to address security risks in the future.

The Pratum Consultant will put together a report of risks at different levels for your business’s executive leadership to review.

What are those risk levels?

Low: Finding creates limited exposure for compromise of user accounts, or unauthorized access to data due to configuration issues, outdated patches and/or policy.

Moderate: Finding does not directly lead to a compromise but could be used in conjunction with other techniques to compromise accounts, or to perform unauthorized activity in the environment.

High: Finding creates a large exposure that could result in a loss of system control, access, application control, and/or exposure of customer data via the compromise of administrative accounts and/or other system functions. It could also create an issue with regards to confidentiality and/or integrity, resulting in many user accounts being compromised, or restricted system functions being accessed.

4. Repeat

A Risk Assessment is not a onetime cure-all. This process should be done on an annual basis to keep up with any new threats and potential changes within the organization.

When Should You Pursue an Information Security Risk Assessment?

There really is no wrong time to do a Risk Assessment. While it should be one of the first considerations of new businesses, it should also be part of your continual security evaluation process. Risk assessments provide immense value to organizations of all sizes, as they allow the IT department to communicate control gaps and security concerns in a language and perspective business leaders can understand.

As stated before, it is possible for an organization to conduct their own Risk Assessment. However, there are benefits to hiring a third-party consultant. Pratum has often identified areas of risk our clients were unaware of. If you’d like to find out more about conducting a Risk Assessment for your business, contact Pratum today!

When COVID-19 first started making headlines, there were a few scams being reported from around the world. While many were focused at the Coronavirus-epicenter, China, the virus and scams are spreading throughout the world.

Many of these scams are phishing scams. Meaning, they are ways for criminals to collect your private information or access to your personal devices. Falling victim to these sorts of crimes can be common during a crisis, when people are not thinking clearly. That’s why it’s good to stay informed and aware of what is out there. Here are some online threats making the rounds you should be aware of!

Anti-Virus Software

One scam being reported is for anti-virus software, but it’s not the kind you probably think of right away. This particular scam is preying on individuals who may not understand what the Coronavirus is or how it works. The website actually makes this absurd claim:

“Our scientists from Harvard University have been working on a special AI development to combat the virus using a windows app. Your PC actively protects you against the Coronaviruses (Cov) while the app is running.” (Source Malwarebytes)

Not only is this scientifically inaccurate, it’s a dangerous site to pursue. Once you download the advertised software, a fake app would be installed and infect your device; allowing the threat actors full access and control.

Free Stuff

Another scam preying on people’s fears right now offers a free “Corona mask” in exchange for the download of an app on your smartphone. The app then demands the right to read your contacts and send SMS messages. After the app is downloaded, you are asked to fill out personal information to be sent the free mask.

While the security experts who discovered and tested this app were not able to submit information, there is reason to believe that personal data would be used for further scams.

Nonetheless, the app accessing contacts and sending out messages was able to spread the virus even more.

Another popular scam claims to be from Netflix and promises free subscriptions to help people get through social isolation/distancing time. The site will ask visitors some questions and then tell the “winner” of the free subscription to share the fraudulent site with 10 friends.

This sort of scam can lead to the scammers requesting more personal information down the road and then using that information to infiltrate your device or private accounts online. If you get this scam from a friend, let them know their account has been hacked!

Census Form

There have been several scams surrounding the U.S. Census this year. One in particular is directed at those looking for federal funds. A news station in Ohio, WOIO, was alerted of a scam in which a man received a Facebook message from a relative telling him to fill out his Census form with a special link in order to get the COVID-19 stimulus money directly deposited into his account. This was reportedly the same money already promised to be coming from the U.S. government in the coming weeks.

These scammers had actually hacked into the other person’s account to send out this dangerous message. The big red flag here is, there is no connection between the stimulus funds and the Census. This is also another good reminder for people to change their passwords frequently, so their accounts are not used to scam loved ones online.

Threats of Infection

Not only are these scams a risk to your online security; some go so far as to threaten your physical health. Barracuda discovered one scam in which the threat actor requested ransom payments, or else the scammer would infect the recipient and their family with Coronavirus.

According to Barracuda researchers, there are three main types of phishing scams related to the Coronavirus: 54 percent were scams, 34 percent were brand impersonation attacks, 11 percent were blackmail, and 1 percent are business email compromise.

Ways to Stay Safe

Some of these scams may seem so obvious, you may not believe anyone would fall victim to them. However, when fear and unprecedented events are occurring it can be difficult for people to think clearly. That’s why it’s so important to stay vigilant during this time with your cybersecurity.

1. Check the source. While you may think the email or website is legitimate because it has a similar name as the original, you need to be sure to read all the fine print. With the Netflix scam mentioned above, the scam website had “Netflix” in the title but was a .net address. Details like this can make a huge difference.

2. Question strangers. If an email or message comes from a source you normally do not communicate with, be leery of them. If you have concerns about ignoring something potentially legitimate, try finding the contact information for who they claim to be somewhere else.

3. Stay educated. Be aware of what scams are making the rounds right now. Having a good knowledge of threats helps keep them at the front of your mind. The more aware you are, the less likely you’ll fall victim to a scam!
