    | Summary | 
    An adversary engages in active probing and exploration activities to determine security information about a remote target system. Often times adversaries will rely on remote applications that can be probed for system configurations. | 
  
  
    | Prerequisites | 
    The adversary must have logical access to the target network and system. | 
  
  
   | Solutions          | Keep patches up to date by installing weekly or daily if possible. Identify programs that may be used to acquire peripheral information and block them by using a software restriction policy or tools that restrict program execution by using a process allowlist.     |
