At Pelican3, we collaborate with many partners in the Managed Service Provider (MSP) and Managed Security Services Provider (MSSP) industry. Risk Assessments are a frequent offering in the service capabilities of both groups. Unfortunately, that offering is often merely a basic vulnerability scan wrapped in the language of Risk Assessment but falls short of the true use and delivery expectations of this actual practice.
A simple vulnerability scan and a full risk assessment are both important tools in cybersecurity, but they serve different purposes and deliver vastly different results. Think of it like checking your car's oil versus getting a comprehensive vehicle inspection before a road trip. Both are useful, but the latter provides a much deeper understanding of what is really going on under the hood. Let's break down the differences in a way that's easy to understand.
Vulnerability Scan
A vulnerability scan is like running a metal detector over the surface of a beach. It sweeps through your systems and applications, looking for known vulnerabilities, outdated software, misconfigurations, or open ports that should not be there. It is a high-level scan that provides a list of technical exposures. You will get a report with a list of issues—think of it as a punch list of things to fix. But that is about it. It does not tell you why those vulnerabilities matter or how much risk they pose to your business. It is a good starting point, but it is not the whole story.
Risk Assessment
A full risk assessment, on the other hand, is a more thorough examination. It is like having a team of experts inspect your entire operation, from your IT infrastructure to your policies, procedures, and even your people. They do not just look at what is wrong; they analyze how it affects your business and what the potential impact could be.
Here is where the real value lies: A risk assessment goes beyond the technical stuff. It asks, "What would happen if these vulnerabilities were exploited?" and "How much could it cost the business?" It examines both the likelihood of an attack and the potential consequences. This assessment helps you prioritize risks based on their severity, allowing you to focus resources where they are needed most. It also considers broader factors like regulatory compliance, business continuity, and brand reputation.
So, while a vulnerability scan might tell you that your firewall has a hole in it, a risk assessment will tell you what that hole could mean for your business. It could be the difference between knowing you have a problem and understanding how that problem could lead to financial loss or, worse, business failure.
In summary, think of a vulnerability scan as a quick health check—it tells you where the symptoms are, but it does not diagnose the underlying condition. A full risk assessment, however, is like a thorough examination by a specialist, helping you understand the root causes and providing a roadmap to recovery. Both are valuable, but if you want to ensure your business stays safe and resilient, a risk assessment is the way to go.
What should a risk assessment look like?
As you proceed and look to perform the more business-tailored assessment, what does it really look like and how do they compare and contrast between industries and frameworks?
Conducting risk assessments is essential across different industries to effectively manage and mitigate risks. Although many organizations adhere to similar foundational steps, each applies its own focus and methodology. Below is an overview of how key entities approach risk assessments, showcasing both the common elements and distinctive aspects.
Common Steps
Most organizations follow these general steps in their risk assessments:
Define the Scope: Establish the boundaries for the risk assessment. What assets, systems, or processes are you evaluating?
Identify Threats and Vulnerabilities: Determine what could go wrong. Identify potential threats and any vulnerabilities that could be exploited.
Determine Risk Levels: Assess the likelihood of threats exploiting vulnerabilities and gauge the impact if they do.
Develop Risk Mitigation Strategies: Once you know the risks, decide how to manage them. Strategies might include mitigation, avoidance, transfer, or acceptance.
Implement and Monitor Controls: Put your chosen security controls in place and keep an eye on their effectiveness.
Variations in Approach
While there's overlap in basic steps, each entity has its own angle on risk assessment. Here is a quick look at how various organizations tackle it:
FFIEC: The Federal Financial Institutions Examination Council focuses on financial institutions. Its guidance, especially the Cybersecurity Assessment Tool (CAT), helps assess cybersecurity risks and business continuity.
AICPA: The American Institute of Certified Public Accountants leans toward accounting and auditing. They emphasize internal controls, confidentiality, and professional conduct, focusing on financial risk assessment.
NIST: The National Institute of Standards and Technology offers a detailed approach to risk assessments, with NIST SP 800-30 providing specific steps for identifying and managing IT risks.
IRM: The Institute of Risk Management has a broader enterprise risk management approach, guiding organizations through the risk assessment process in a wider business context.
PMI: The Project Management Institute integrates risk assessment into project management, focusing on identifying and mitigating risks throughout a project's lifecycle.
OWASP: The Open Web Application Security Project zeroes in on web application security, offering a framework to assess risks related to web vulnerabilities.
SANS: The SANS Institute is all about cybersecurity training and offers practical advice for proactive risk assessment and continuous monitoring.
ISACA: ISACA's COBIT framework and Risk IT guide IT governance and risk management, providing a comprehensive approach to risk assessment in IT contexts.
CIS: The Center for Internet Security lays out critical security controls for cybersecurity. Their approach is about implementing these controls and assessing their effectiveness.
ISO: ISO/IEC 27001 is a globally recognized standard for information security management systems (ISMS). It includes specific requirements for risk assessment.
NERC: The North American Electric Reliability Corporation focuses on energy sector risks. Their approach to risk assessment is tailored to critical infrastructure.
NAIC: The National Association of Insurance Commissioners provides regulations for insurance companies. It focuses on compliance with state insurance laws and risk-based capital requirements.
GDPR: The General Data Protection Regulation deals with data protection in the EU. It requires data protection impact assessments (DPIAs) for high-risk data processing activities.
NYDFS: The New York Department of Financial Services Cybersecurity Regulation focuses on risk-based cybersecurity for financial institutions and insurance companies.
American Bar Association: The ABA guides legal professionals on risk assessment, emphasizing ethical practices and client confidentiality.
Key Takeaway
While the basic steps in risk assessment are similar across entities, the details vary based on industry focus and specific needs. Choose a framework that aligns with your industry and regulatory requirements to keep your risk assessment practices current. Effective risk assessment is critical for managing risks and maintaining compliance.
