Application whitelisting in RHEL

by Danila Vershinin, September 1, 2021

How to fix we are looking to apply an `application whitelisting` mechanism in rhel workstations, where users are allowed to run certain binaries, while running anything else is not allowed. for example, trusted applications, let’s say gedit, is allowed, while running applications/scripts that are not whitelisted will be rejected. `selinux` is a `behavioral whitelisting`, not sure if `application whitelisting` is feasible.- is there any mechanism to apply such thing in rhel? and products in the market you’re aware of that performs something similar?- restrict the execution of executable and script.- does application server whitelist or control executable and script executor such as `microsoft applocker`, cli setups to restrict the execution of executable and script to an approved set and authorised individuals?
