Cyber adversaries continuously scan the internet for vulnerable systems. Conducting regular vulnerability assessments and penetration tests helps you find and fix weaknesses before attackers exploit them. While our earlier posts cover patch management, testing validates whether patches have been applied correctly and reveals misconfigurations.
A vulnerability assessment uses automated scanning tools to detect missing patches, weak encryption, misconfigurations, and known flaws in software. Penetration testing goes a step further by simulating an attacker’s actions to exploit vulnerabilities, pivot through your network, and access sensitive data. Both services can be performed by in‑house security teams or external specialists.
Start by defining the scope: which systems, networks, and applications are in scope? Determine the frequency; quarterly scans are common, but critical systems may require more frequent assessment. Prioritise identified vulnerabilities based on severity and likelihood of exploitation. Use industry scoring systems (such as CVSS) to triage fixes.
Combine automated testing with manual reviews. Automated scanners catch low‑hanging fruit, while skilled testers can identify logic flaws or chained exploits. After completing the test, hold a remediation workshop to address issues, update configuration baselines, and refine secure development practices. Regular assessments demonstrate due diligence and may be mandated by frameworks such as PCI DSS and SOC 2.
In addition, its a good idea to engage in with a vendor that can help you track your compliance and walk you through the process. A great option for SMB’s is Scrut Automation. They provide automated tools to track potential vulnerabilities and can also perform penetration testing for compliance. They will guide you through the entire process and they are much more affordable than other firms.
