CyberArk Endpoint Privilege Manager supports granular application-control policies that use different identifying characteristics to determine whether executable content should be allowed, elevated, restricted, or blocked.
Application parameters enable administrators to create flexible policies based on attributes and command-line conditions associated with application execution.
The principal advantage is configurability. Parameters can be adjusted as applications and operational requirements evolve without necessarily rebuilding the entire application policy.
However, insufficiently constrained parameters may create opportunities for bypass. If an attacker can manipulate an accepted parameter or exploit an overly broad matching condition, the application could behave differently from the administrator's intended policy.
Checksums provide a different form of identification. A cryptographic checksum can bind a policy to a specific file version, making it particularly useful for internally developed scripts or tightly controlled executables.
The limitation is maintenance overhead. Modifying the underlying file generally changes its checksum, requiring administrators to update the associated policy.
In environments where scripts change frequently, this can create substantial operational effort.
Neither approach is universally superior. Effective application control depends on identifying the appropriate combination of file attributes, cryptographic hashes, publishers, paths, parameters, and execution context.
