Step 1: Identify systems and define scan scope
Defining your vulnerability scanning scope is crucial for comprehensive security assessment. You will map out all digital assets and determine precisely which systems require investigation.
Begin by creating a comprehensive inventory of all networked devices and digital infrastructure. This means documenting every computer, server, network switch, router, cloud service, and web application your organisation uses. The Ministry of Justice’s guidance on vulnerability scanning recommends maintaining a detailed asset register as the foundation of effective scanning.
Break down your asset inventory systematically. Start with network infrastructure components like routers and switches, then move to end-user devices such as laptops and desktops. Include all cloud-hosted services, web applications, and third-party platforms integrated into your business operations. Pay special attention to systems handling sensitive data or connected to critical business processes.
Prioritise your assets based on their potential security risk and business impact. Not every system requires the same level of scrutiny. Mission-critical infrastructure and systems handling customer data should receive more intensive scanning compared to peripheral systems.
Here is a comparison of types of digital assets and considerations for scanning:
Asset Type | Unique Scanning Challenges | Typical Priority Level |
Network Devices | Firmware updates, configuration depth | High for core routers |
End-user Devices | User privacy, varied software | Medium, based on risk |
Cloud Services | Access management, provider controls | High for critical data |
Web Applications | Code flaws, dependency vulnerabilities | High for business sites |
Third-party Apps | Vendor patching, integration risks | Variable, assess impact |
Key considerations for defining scan scope include:
Identifying all network-connected devices
Documenting cloud and on-premises systems
Understanding interdependencies between different systems
Assessing potential vulnerabilities in each asset category
Professional advice: Create a living document for your asset inventory that can be regularly updated. Technology landscapes change rapidly, and maintaining an accurate, current register is essential for ongoing security management.
Step 2: Configure scanning tools and permissions
In this crucial phase, you will set up your vulnerability scanning tools and establish appropriate access permissions to ensure comprehensive and secure scanning across your digital infrastructure. This step transforms your asset inventory into an actionable security assessment process.
Begin by selecting an automated vulnerability scanning tool that matches your organisation’s specific requirements. The UK Government Security Group recommends implementing continuous automated processes that efficiently identify and address potential security risks. When configuring your tool, ensure it can comprehensively scan all identified systems including web applications, network infrastructure, cloud services, and endpoint devices.
Carefully configure permission levels for your scanning tools. You will need administrative or elevated access credentials to perform thorough scans across different systems. However, apply the principle of least privilege carefully the scanner should have only the minimum permissions required to complete its task. This approach prevents potential security risks while maintaining comprehensive scanning capabilities.
Establish a scanning schedule that balances thoroughness with minimal operational disruption. Most organisations benefit from weekly or monthly comprehensive scans, with additional targeted scans following significant system changes or updates. Configure your tools to generate detailed reports that highlight vulnerabilities by severity level, enabling your team to prioritise remediation efforts effectively.
Key configuration considerations include:
Setting appropriate scan frequency
Defining scan depth and comprehensiveness
Configuring credential management
Establishing reporting and alert mechanisms
Ensuring minimal system performance impact
Professional advice: Always maintain a test environment where you can validate scanning tool configurations before deploying them across production systems. This approach helps prevent unintended disruptions and ensures your vulnerability management strategy remains robust and reliable.
Step 3: Run vulnerability scans across target assets
This stage involves executing comprehensive vulnerability scans across your identified digital assets to uncover potential security weaknesses and configuration risks. Your goal is to systematically assess each system and generate detailed insights about your organisational security posture.
Continuous vulnerability discovery throughout your service lifecycle requires a methodical approach to scanning. Begin by initiating automated scans on your prioritised systems, starting with the most critical infrastructure. Most vulnerability scanning tools will automatically probe for known security vulnerabilities, misconfigurations, outdated software versions, and potential entry points for cyber attacks.
Ensure your scanning process covers multiple dimensions of security assessment. This means looking beyond simple software version checks and examining deeper configuration issues, network vulnerabilities, and potential compliance gaps. Pay special attention to systems handling sensitive data, such as customer information, financial records, or critical business operations.
Monitor your scans in real time and be prepared to interrupt or pause processes if they begin to impact system performance. Some scanning tools allow you to set bandwidth limitations or schedule scans during off peak hours to minimise operational disruption. Configure your tools to generate comprehensive reports that categorise vulnerabilities by severity level, enabling your team to prioritise remediation efforts strategically.
Key scanning execution considerations include:
Running comprehensive network and application scans
Verifying scan coverage across all asset types
Checking scan performance and system impact
Generating detailed vulnerability reports
Ensuring consistent scanning methodology
Professional advice: Always validate scan results with manual verification, especially for critical systems. Automated tools are powerful but not infallible, so combining automated scanning with expert human review provides the most robust security assessment approach.
Step 4: Review and prioritise detected vulnerabilities
After completing your vulnerability scans, you enter a critical phase of analysing and ranking the discovered security weaknesses. This step transforms raw scanning data into actionable intelligence that will protect your organisation’s digital infrastructure.
The scanning process typically generates a comprehensive report highlighting multiple vulnerabilities across different systems and severity levels. Vulnerability assessment strategies recommend prioritising risks based on potential business impact rather than simply counting the number of detected issues. Focus your initial attention on vulnerabilities that could cause significant operational disruption or expose sensitive data.
Evaluate each vulnerability using a structured risk assessment framework. Consider factors such as the potential attack surface, ease of exploitation, potential financial or reputational damage, and the complexity of remediation. Critical vulnerabilities that could provide direct access to sensitive systems or data should receive immediate attention and rapid mitigation planning.
Create a detailed remediation roadmap that categorises vulnerabilities into immediate, short term, and long term action items. Assign clear responsibilities to specific team members or departments, ensuring accountability for addressing each identified security weakness. Implement a tracking system that allows you to monitor progress and ensure no critical vulnerabilities remain unaddressed for extended periods.
Key prioritisation considerations include:
Assessing potential business impact of each vulnerability
Evaluating ease of potential exploitation
Understanding system interconnectedness
Estimating remediation complexity and resources required
Maintaining a comprehensive vulnerability tracking mechanism
Professional advice: Develop a continuous vulnerability management approach where regular scanning and prioritisation become a standard part of your organisational security workflow. Treat vulnerability management as an ongoing process rather than a one time activity.
Step 5: Remediate issues and verify resolution
With your vulnerabilities identified and prioritised, you now enter the critical phase of actively resolving security weaknesses and confirming their complete elimination. This stage transforms theoretical risk assessment into practical security improvement.
The Ministry of Justice’s vulnerability management guidelines emphasise applying patches according to a structured schedule, ensuring systematic and comprehensive remediation. Begin by addressing the most critical vulnerabilities first, using a combination of software updates, configuration changes, and targeted security interventions. For each identified vulnerability, develop a specific remediation strategy that includes precise steps to eliminate the security risk.
Implement your remediation plan methodically, tracking each vulnerability through its complete resolution cycle. This means not just applying patches or making configuration changes, but also documenting each intervention and its expected outcome. Some vulnerabilities might require multiple steps or collaboration across different technical teams, so maintain clear communication and accountability throughout the process.
After implementing remediation measures, conduct thorough verification scans to confirm that the vulnerabilities have been completely resolved. These validation scans should replicate the original vulnerability assessment, ensuring that your interventions have successfully closed the identified security gaps. Pay special attention to any interconnected systems that might have been indirectly affected by your remediation efforts.
Key remediation and verification steps include:
Prioritising vulnerabilities by severity and potential impact
Developing targeted remediation strategies
Implementing precise technical interventions
Documenting all remediation activities
Conducting comprehensive verification scans
Confirming complete vulnerability resolution
Professional advice: Create a standardised remediation template that guides your team through consistent, repeatable steps for addressing different types of security vulnerabilities. This approach ensures nothing is overlooked and builds institutional knowledge about effective security management.
Step 6: Document findings and schedule ongoing scans
The final stage of your vulnerability scanning workflow involves comprehensive documentation and establishing a sustainable scanning strategy that ensures continuous security monitoring. Your goal is to create a robust record of your security assessments and implement a proactive scanning schedule.
Ministry of Justice guidelines emphasise maintaining detailed scanning logs for potential forensic investigation and security analysis As such, document each vulnerability scanning exercise with meticulous detail. Your documentation should include comprehensive scan results, identified vulnerabilities, remediation actions taken, and their current status. Develop a standardised reporting template that captures consistent information across different scanning cycles.
Establish a strategic scanning schedule that aligns with your organisation’s risk profile and operational requirements. This means determining appropriate scanning frequencies for different types of systems and infrastructure. Mission critical systems might require weekly or monthly scans, while peripheral systems could be assessed less frequently. Consider factors such as system complexity, data sensitivity, and regulatory compliance requirements when designing your scanning intervals.
Create a centralised repository for all vulnerability scanning documentation that allows easy access and review by relevant team members. This digital archive should track the evolution of your security posture over time, providing valuable insights into emerging trends and the effectiveness of your remediation strategies. Ensure that your documentation is secure, version controlled, and accessible only to authorised personnel.
Key documentation and scheduling considerations include:
Creating comprehensive scanning reports
Tracking vulnerability remediation progress
Establishing systematic scanning intervals
Maintaining a secure documentation repository
Enabling continuous security improvement
Professional advice: Implement an automated documentation and notification system that can generate reports, highlight critical findings, and alert relevant team members about emerging security risks without requiring manual intervention.
