Organizations routinely encounter a myriad of cyberthreats that jeopardize their data, operations and reputation. To address these constantly evolving threats, organizations need consistent methodologies and tools to proactively identify security gaps and weaknesses.A well-designed risk assessment will empower your organization to prioritize security initiatives that have the most value and a gap analysis can help you identify non-compliance and avoid potential fines or attacks. The power is in understanding when and how to apply the right tool at the right time.
A cyber risk assessment is a tool that helps organizations identify and prioritize risks associated with threats that are relevant to their unique environment. It’s a systematic process of identifying likely threats, analyzing controls designed to address those threats, evaluating the associated consequences of any identified gaps or weaknesses, assigning a risk based on likelihood and impact and identifying controls (preventative or detective) that can help to mitigate them.
A risk assessment is a methodology that can be applied to a number of things. Changing the threats you evaluate your controls against is the key to creating the appropriate assessment. Examples include:
Cyber risk assessments help organizations in numerous ways. They help identify security priorities, help businesses gain a clearer understanding of their risk posture; enable business leaders to make informed investment decisions; improve compliance with regulations and reduce the risk of fines and other legal issues; boost stakeholder confidence in cybersecurity and enable cost savings through the avoidance of potential cybersecurity blunders and incidents.
A risk assessment can be conducted in various business use cases such as:
A gap analysis provides organizations with a comprehensive view of the initiatives needed to achieve compliance or alignment with a security goal or standard. A typical gap analysis report will highlight the weaknesses and variances that exist between current security controls, performance or capabilities, versus desired outcomes, best practices or industry-accepted standards. Reports might also include a risk rating against the identified gaps (for prioritization) and provide actionable recommendations to bridge the gaps, including timelines and responsibilities for implementing changes.
Gap analysis comes in many different types including:
Since a gap analysis compares the current state of cybersecurity with a target state, it is particularly helpful in identifying missing controls, processes, policies, infrastructure or skills. For example, it can help pinpoint areas in incident response processes that may be lacking or need more robust preparation. It can help highlight shortcomings in application security or secure software development processes (when benchmarked to frameworks such as SSDLC and SSDF).
A gap analysis can be deployed in scenarios such as:
The fundamental difference between a gap analysis and a risk assessment is that a risk assessment can be tailored to be more relevant to an organization’s unique set of threats against its unique technical and business environment, helping the business prepare for current and developing threats.
A gap analysis identifies discrepancies between current cybersecurity practices and desired cybersecurity practices. A risk assessment is also more focused on the impact and likelihood of events happening, which helps prioritize remediation activities.
How often a gap analysis is performed depends largely on the maturity of your program; as maturity rises, the frequency may drop off a bit. I would recommend performing them once or twice a year to start, but then every two years may be appropriate as the information security program matures. A comprehensive risk assessment should be performed at least once a year, as required by many of the current frameworks, but limited-scope risk assessments should be performed regularly as your program matures.
Using your compliance framework as input for the risk assessment is a great way to kill two birds with one stone and save time and money. The gap analysis will be risk-rated to assist in the prioritization of your gap remediation planning.
Note: Compliance frameworks don’t evolve and update as fast as the threat environment, so consider adding additional threats to your assessments as they develop.
Remediation is the goal. Getting and maintaining priority on security remediations can be a challenge, but there are a few tips to help make sure they are successful:
Risk management techniques are not just optional exercises but essential tools that help organizations avoid business disruptions by strengthening defenses, maintaining compliance, adapting to an ever-evolving threat landscape and making informed decisions. Risk assessments and gap analyses should be a common practice, organizations should leverage these tools whenever there’s a significant organizational change, an emerging threat, or an update to a compliance mandate or regulation.
