Another financial quarter, another Board of Directors meeting on your schedule. As a Chief Executive Officer (CEO), the pressure is on. You need to set and execute your company’s organizational and business strategies while ensuring that you consistently achieve revenue targets. With a volatile economy, allocating resources and mitigating risk begins to feel overwhelming.
If you’re the Chief Financial Officer (CFO), you’re focused on revenue and spending. You’re worried about your current market segment, rising costs, and budget requests.
As the next Board of Directors meeting approaches, your Chief Information Security Officer (CISO) hands you the most recent vulnerability assessment. Now, you need to work as a team to decode the technical details and translate them into business impact.
Understanding how your cybersecurity vulnerability assessment report fits into your strategic c-suite mission enables you to allocate resources and mitigate cybersecurity risk more effectively and efficiently.
What are a vulnerability, a vulnerability assessment, and a vulnerability assessment report?
If you’re talking about vulnerabilities and vulnerability assessments from a technical point of view, it’s easy to feel like you’re going down a Matrix-like rabbit hole. When you approach them strategically, they become more valuable.
Vulnerability
A security vulnerability is any system weakness that attackers can use to gain unauthorized access to a website, application, network, or device.
Some examples of vulnerabilities include:
Software or operating system “bugs”
Gaps in input validation
Outdated software
Infected plugins
For non-technical c-suite members, vulnerabilities represent risks to the organization. Some risks include:
Data breaches
Compliance violations
Business interruption
If you have vulnerabilities that attackers can use to steal sensitive information or shut down your business operations, they become a strategic and revenue problem.
Vulnerability Assessment
A vulnerability assessment is a process that usually uses automated tools to identify, categorize, and report security vulnerabilities found in websites, applications, networks, or devices.
For a comprehensive evaluation of vulnerabilities impacting your environment, you probably use more than one of the following scanners:
Network
Web application
Internet of Things (IoT) device
Container security
Host-based
Wireless
Database
Port
Although both vulnerability assessments and penetration tests review the security weaknesses affecting your organization, they differ in several ways:
A vulnerability assessment is an automated process while a penetration test is manual
A vulnerability assessment lists security weaknesses while a penetration test tries to use the vulnerabilities to gain unauthorized access
A vulnerability assessment can be conducted regularly while a penetration test is usually conducted annually because it’s expensive
Vulnerability Assessment Report
The vulnerability assessment report is the document that details all the vulnerabilities identified during the vulnerability scan. Your vulnerability assessment report aggregates the various types of vulnerabilities detected, indexes them by severity, and provides remediation suggestions.
7 Steps to a Vulnerability Assessment
From start to finish, the vulnerability assessment process consists of seven discrete steps. Some steps, like the initial assessment, are done once. You will repeat other steps regularly because you need to continuously review and monitor your environment as researchers publish new vulnerabilities.
1. Engage in Initial Assessment
Your initial assessment includes:
Identifying all assets
Defining risks
Assigning responsibility for assets
Engaging in a business impact analysis to determine risk level, risk tolerance, and risk appetite for each device or service
Determining countermeasures, residual risk treatment, risk mitigation practices, and policies for each device or service
This is also when you define your critical assets or those resources whose security and availability are critical to business operations and revenue.
2. Define System Baseline
After completing the initial assessment, you:
gather system data to review devices for services, processes, or ports that create security weaknesses
Determine basic secure configuration for each device, software, and driver
When defining the system baseline, you should also ensure that you know what sensitive data could be compromised. This includes:
Knowing what devices, networks, applications, and databases contain sensitive data
Understanding attack paths between different devices, networks, applications, and databases
3. Perform a Vulnerability Scan
Vulnerability scanners review devices and assets connected to your network looking for common vulnerabilities and exposures (CVEs). Vulnerability scanners use CVEs to identify weaknesses like:
Open ports
Running services
Outdated software versions
Misconfigurations
4. Analyze the Vulnerability’s Impact
Once you have the vulnerability assessment, you determine the potential business impact that the vulnerability could have on your organization.
Typically, the analysis considers the following:
Common Vulnerability Scoring System (CVSS) Score: Industry standard determining CVE severity as critical, high, medium, low, or none
Threat: potential for adversaries to use the vulnerability during an attack
Exploitability: ease with which attackers can use the vulnerability to gain unauthorized access to systems, networks, or assets
During the analysis, you review the potential business impact that the vulnerability poses. Typically, this means correlating:
CVE information
Threat intelligence
Current IT architecture, including connections to the public internet and connected assets
Your analysis should enable you to prioritize your vulnerability management activities so that you patch your critical assets and riskiest attack paths first.
5. Create a Vulnerability Assessment Report
Your vulnerability assessment report includes the details and recommendations that align to your business and security objectives. The report provides the narrative that brings together:
Vulnerability
Business impact
Next steps
With this report, you understand the next steps and can make informed decisions around how to proceed.
6. Consistently Repeat Activities
A vulnerability assessment provides a point-in-time view of your security posture. Your risk continuously changes. As you add new resources, whether it’s Software-as-a-Service (SaaS) applications or virtual machines, your risk changes. As you add new devices to your networks, your risk changes. Every time researchers publish a new vulnerability, your risk changes.
Depending on your environment, you should complete a vulnerability assessment anywhere from weekly to quarterly. Additionally, you want to incorporate your vulnerability assessment into your risk management strategy, repeating the process whenever you make changes to your systems.
7. Improve Vulnerability Management Processes
Iteration is fundamental to establishing a cyber resilient organization. Your risk continues to evolve, especially in dynamic cloud environments. You need to review, iterate, and improve on your vulnerability management processes by continuously monitoring assets and mapping them to new vulnerabilities.
As your environment changes, your business impact assessment will change, and you need to change your processes in response.
What should be in a vulnerability assessment report?
1. Executive Summary
The executive summary provides an overview that enables you to get the high-level understanding necessary to align vulnerability management, security, and operational goals.
A vulnerability report’s executive summary should include:
Objectives: time period covered, alignment with security goals
Scope: Assets and/or networks sccanned
Testing Narrative: Vulnerabilities detected, vulnerability criticality, business risk impact
Remediation Summary: Patches applied, controls added
2. Assessment Overview
In this section, the vulnerability assessment report gives insights into vulnerabilities and their technical details to support the results outlined in the executive summary.
The assessment overview section should include:
Scan results: list of assets and vulnerabilities for each, false positives, false negatives
Tools: Scanner types, makes, and models used
Risk assessment: List of vulnerabilities detailed by severity
3. Results and Mitigation Recommendations
Finally, the vulnerability assessment report outlines appropriate mitigation steps. This can include patches that you need to apply or other risk mitigation controls.
Why you need a vulnerability assessment report
As a senior leadership team member, you need information that enables you to incorporate security into your current role. Fundamentally, the vulnerability assessment report’s executive summary should provide this information. However, vulnerabilities can be highly technical. Often, visualizations can help you understand risk more effectively so that you can make data-driven decisions when performing your responsibilities.
Compliance Purposes
Vulnerability management is a fundamental compliance requirement. Nearly every security and privacy compliance framework or mandate incorporates secure baselines, configuration management, and vulnerability scanning. Additionally, nearly every mandate relies on your ability to analyze and mitigate risk.
Your vulnerability assessment report enables you to gain visibility into:
Assets with vulnerabilities
Number of assets with critical vulnerabilities
Attack paths that threat actors can exploit
Further, your data tells you about a vulnerability’s business impact. Correlating data breach cost information with your industry vertical, company size, and open source threat intelligence enables you to quantify risk in dollars.
Resource Allocation
Senior leadership sets the annual budget, allocating financial resources that enable teams to purchase tools or hire staff. Having robust vulnerability management processes enables both your vulnerability management and security teams.
When researchers publish a new vulnerability, attackers actively look for ways to exploit it. Your vulnerability assessment report can give you visibility into whether you have appropriate staffing for vulnerability management efforts needed to mitigate security risks. Too many potential exploits means you need more staff.
Additionally, if your vulnerability assessment report indicates that you have a high number of unpatched critical assets, you might need to add more staff to your vulnerability management team.
