System Time Discovery Mitigation
Benign software uses legitimate processes to gather system time. Efforts should be focused on preventing unwanted or unknown code from executing on a system. Some common tools, such as net.exe, may be blocked by policy to prevent common ways of acquiring remote system time.
Identify unnecessary system utilities or potentially malicious software that may be used to acquire system time information, and audit and/or block them by using whitelisting (Citation: Beechey 2010) tools, like AppLocker, (Citation: Windows Commands JPCERT) (Citation: NSA MS AppLocker) or Software Restriction Policies (Citation: Corio 2008) where appropriate.
