Regular reviews are essential to confirm adherence to the organization's information security policies, as well as topic-specific policies, rules, and standards. This ensures that information security is implemented and operated in alignment with the organization's overall information security framework. In the event of non-compliance, managers should identify causes, assess the need for corrective actions, implement those actions, and subsequently review their effectiveness.
The ISMS should monitor the implementation of the tasks and guidelines recorded therein.
The task owner should regularly review the implementation status of the ISMS as a whole.
The organization regularly conducts a vulnerability scan, which searches for vulnerabilities found on computers, workstations, mobile devices, networks or applications. It is important to scan even after significant changes.
It should be noted that vulnerable source code can be from operating system software, server applications, user applications, as well as from the firmware application as well as from drivers, BIOS and separate management interfaces (e.g. iLo , iDrac). In addition to software errors, vulnerabilities occur from configuration errors and old practices, such as the use of outdated encryption algorithms.
Following security guidelines can be monitored either technically or directly by asking / testing employees.
Static scans on code are the first step in detecting risky vulnerabilities. However, once a service has been deployed, it is vulnerable to new types of attacks (e.g., cross-site scripting or authentication issues). These can be identified by penetration testing.
