Vulnerability assessment best practices for enterprises

Measure Twice, Cut Once

Compliance and Life Cycles

VA has a never-ending life cycle of continual scans, reports, assessments, remediations, and evaluations and must be addressed in such a way to be truly effective. Daily, new attack signatures are developed, viruses and worms are written, buffer overflows are discovered, and changes in an organization's infrastructure and new technologies are developed that increase the susceptibility of an organization to vulnerabilities. Each of these actions affects the risk posture of the organization. Any one piece of the life cycle cannot be effective without the other.

Once the VA is complete, the reports have been presented, and the organization has been briefed, you need to give them the tools to stay protected against new vulnerabilities. No interconnected IT environment is 100% removed from potential attacks, but if you can impress upon the organization you are working with the importance of regularly scanning their systems, they will be better off than when you arrived, which is your ultimate goal.

Conclusion

A single piece of malware can cause widespread trauma to an organization and even significant injury to an entire region of the world. A good VA program can help prevent these problems from ever happening. A VA program can assist with reducing an organization's overall risk level and, in turn, allow an organization to perform effective due diligence in order to uncover the true vulnerabilities. By creating a comprehensive VA program, an organization can add another layer to its in-depth defense strategy. By identifying key vulnerabilities and providing future mitigation guidance to your organization, you will be strengthening your risk management program as well. A successful and comprehensive VA program can help any organization safeguard its critical information and systems.
