Description
Maintaining an audit trail of system activity logs can help identify configuration errors, troubleshoot service disruptions, and analyze compromises that have occurred, as well as detect attacks. Audit logs are necessary to provide a trail of evidence in case the system or network is compromised. Collecting this data is essential for analyzing the security of information assets and detecting signs of suspicious and unexpected behavior. Enabling PowerShell script block logging will record detailed information from the processing of PowerShell commands and scripts. Additionally, enabling invocation logging will log events when the invocation of commands and scripts start or stop. This can provide additional detail when malware has run on a system. This may result in a high volume of events.
