As a strong Windows command file language, PowerShell is used by both IT specialists and attackers. PowerShell is an on-board command line tool. You can download and execute codes from another system. PowerShell enables a unique access on Windows computers. As system managers use PowerShell to automatize various tasks, it is activated on many computers. As the files and commands are not written on a disc, the malicious use of them are generally not prevented or perceived by traditional AV/HIPS. Despite these difficulties, it is not ideal to remove PowerShell due to the benefits it provides for IT managers. A widespread problem we face is the lack of saving on the usable log in order to understand the actions of the attacker conducted with PowerShell. These logs will assist you in obtaining the necessary visibility in order to better respond to, search, and correct the attacks related to PowerShell.
