Accessing Files While Scanning

L1 Bithead

Hello, this might be a dumb question but I'm trying to find any documentation that might back it up.

 

Basically, when conducting a system scan some apps can't be executed because they try to access certain .dll files which are being used or are open by Cortex XDR. I just want to make sure this is expected behavior and if there's any workaround.

 

Thanks!

Hi Samuraihack,

 

While traditional anti-virus software may have locked files during its scanning, it would be more accurate to say that there are multiple components within the Cortex XDR's multi-method protection approach, preventing a process from running or functioning successfully if the proper exceptions have not been made. Information about the file analysis and protection flow can be found here.

 

Creating rule exceptions would be the next step to permit your software to run after determining through your investigations which Cortex XDR Agent module is preventing the software from executing successfully. I will note that this investigation may require advanced knowledge of the environment and an intermediate understanding of the architecture for the Cortex XDR Agent.

 

Please have a look at the following video to learn more.

Thanks for the reply! This certainly clarifies my doubt. We offered our customer the option to reschedule the scans to a more convenient time or to configure the required exceptions.
