The potentially dangerous test setting allows the users to enable a set of plugins within Holm Security VMP's library of vulnerability checks which may have a negative effect on the network, device or application being tested. Tests that perform active break-in attempts category should be treated as an extension of Potentially dangerous tests as the main concept remains the same. Some examples of the impact can be Denial of Service conditions, modification of application configurations, restarting servers, etc. Therefore, we recommend the potentially dangerous test and tests that perform active break-in attempts setting to be used in a pre-production environment.
By enabling potentially dangerous tests and tests that perform active break-in attempts, the Holm Security scanner will not only run the "safe" plugins that will allow the user to understand which patches are required or not but also run tests that are necessary for Holm Security VMP to understand if a network patched has been applied or not, which in some cases aren't easily done and have a negative impact.
Potentially dangerous tests and tests that perform active break-in attempts include around 3000 plugins that aren't automatically performed when running a scan without those settings enabled.
