2.5 Custom scan A custom scan is a network audit based on parameters, which you configure on the fly before launching the scanning process. Various parameters can be customized during this type of scan including: • Type of scanning profile to use (i.e. the type of checks to execute/type of data to retrieve). • Scan targets • Logon credentials In custom scans, scan profiles are organized under 3 profile groups: • Vulnerability assessment: This group contains profiles that scan target computers for network threats based on guidelines provided by OVAL/CVE and SANS TOP20 bulletins. • Network & Software audit: This group contains profiles that scan target computers for system information such as OS information, installed applications and USB devices connected. • Complete/Combination scans: This group contains Full Scan profiles that audit target computers for a wide-array of threats and system information. When to use Custom Scans? It is recommended to use custom scans: • When performing a onetime scan with particular scanning parameters/profiles. • When performing a scan for particular network threats and/or system information. • To perform a target computer scan using a specific scan profile. 2.5.1 How to launch a Custom Scan To perform a custom scan: 1.
