The famous quote "There is nothing permanent except change" has a direct relation to the world of IT security: systems or services that are secure and reliable at this moment can become a security threat within hours. The only solution to this problem is constant management and maintenance of the systems to ensure that they are up-to-date with the current security standards.
This task is performed by constantly monitoring the immense amount of on-line resources for warnings and alerts. Alerts relevant to the organizational infrastructure must be identified, analyzed, and processed. The vulnerable systems or services must be patched or, if patching is not immediately possible, the systems and services must be protected as much as possible from new threats until the vulnerability has been resolved. Often the substantial resources needed to perform this task are not available, and the newly discovered vulnerabilities remain present for weeks, months, and sometimes years. This is one of the main reasons why Internet worms such as "SQLSlammer" tend to appear with alarming frequency and are still widely present, despite the fact that almost all vulnerabilities used by those worms have long been well known.
Codeangels Solutions offers a set of "Vulnerability Management" services for customers who have no resources or insufficient resources to perform the tasks required to stay up-to-date with security standards:
