They will also review your current controls and evaluate their effectiveness.įor example, a financial management company turned to Pratum when it realized that investors were choosing portfolio managers based, in part, on a company’s strength of cybersecurity. These experts look over a number of key factors you may not have considered.Ĭybersecurity consultants analyze your organization’s structure, policies, standards, technology, architecture, controls, and more to determine the likelihood and impact of potential risks.

But you’ll probably still need help from cybersecurity consultants to carry out a full assessment.

#RISK PROBABILITY AND IMPACT ASSESSMENT EXAMPLE HOW TO#

Reading through how to determine likelihood and impact can help you understand first steps in your risk assessment process. Acceptance – Formal acknowledgement of the presence of risk with a commitment to monitor it.Transfer – Sharing of risk with partners, such as through insurance or other ventures.Adding multifactor authentication, for example, greatly reduces the probability of a hacker getting into a user’s account. Mitigation – Reduction of the probability of a risk’s occurrence or of its impact.You could, for example, prevent employees from accessing certain parts of your system on mobile devices. Avoidance – Elimination of the cause of the risk.Mitigating measures you may apply include: After you apply those controls, you are left with what we call “residual risk.” If the residual risk level after mitigating controls is still higher than you prefer, then additional risk management measures and techniques should be introduced. Residual risk – 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. Where is your system at its weakest when no other security measures are in place to protect them? Which risks deserve the highest rating based on their likelihood and potential impact?Ģ. Inherent risk – This is the risk level and exposure your system faces without taking into account any mitigating measures or controls that are actively in place.

Now that you know the formulas for determining likelihood and impact during a risk assessment, it’s time to focus on specific risks.ġ.

If you’d like to read detailed guidelines on how to rate risks by various factors, consult NIST SP 800-30. If a breach could shut down a hospital’s life-support equipment, for example, that risk obviously deserves serious consideration on your priority list. Keep in mind that a very High impact rating could make a risk a top priority, even if it has a low likelihood. And the impact would be very high if a hacker got access to a user account that controls financial transactions.

There’s at least a medium likelihood of one of those employees making this mistake. That risk gets a Low rating.īut the formula changes if the risk is an employee in the Accounts Payable department clicking a phishing link. Those materials are already publicly available on your website, etc., so unauthorized access to them does no harm. That event may have a medium likelihood, but it has a very low impact. You could also represent this concept with a simple chart like this one:įor example, let’s consider the risk of a hacker getting access to a folder containing all of your public-facing marketing materials. Each organization’s residual risk rating may differ based on the likelihood and impact that each control deficiency introduces. Combining likelihood and impact produces a residual risk rating of Low, Medium or High. Impact measures how much disruption you’ll face if the threat actually occurs.

But if you’ve applied the latest software patches that fix the problem, then the vulnerability cannot be exploited, and the threat has been eliminated. For example, if there’s a known security flaw in older versions of software you use, there’s the threat of hackers exploiting that particular vulnerability to compromise your system. The first part of the formula (Threats x Vulnerabilities) identifies the likelihood of a risk. Risk = (Threat x Vulnerabilities) x Impact
