PenTest+

The commands executed by the penetration tester are intended to clear the Bash history file while preserving its timestamp. The sequence starts by creating an empty file named 'temp'. The 'touch -r .bash_history temp' command then ensures that the 'temp' file has the same timestamp as the original '.bash_history' file. Finally, the 'mv temp .bash_history' command replaces the existing '.bash_history' file with the empty 'temp' file, effectively clearing the Bash history while keeping its original modification time unchanged. This action is most likely performed to cover tracks and make it harder for incident responders to detect the tester's activities on the system.

A compliance-based penetration test is primarily concerned with determining the efficacy of a specific set of security standards. The purpose of this test is to ensure that the organization adheres to certain security standards and regulatory requirements, such as HIPAA, PCI-DSS, and SOX. This involves assessing whether the security controls and processes in place meet the necessary criteria to protect sensitive data and maintain compliance with the relevant regulations.
