Troubleshoot SELinux alerts
To check if SELinux is enabled, enter the following command: 'sestatus'.
When the SELinux policy is set to enable and block ds_agent, the following alert sample might appear in the system log or SELinux log (
[TIMESTAMP] [HOSTNAME] python: SELinux is preventing [/PATH/BINARY] from 'read, write' accesses on the file/var/opt/ds_agent/dsa_core/ds_agent.db-shm. ***** Plugin leaks (86.2 confidence) suggests ***************************** If you want to ignore [BINARY] trying to read write access the ds_agent.db-shm file, because you believe it should not need this access. Then you should report this as a bug. You can generate a local policy module to dontaudit this access. Do ausearch -x [/PATH/BINARY] --raw | audit2allow -D -M [POLICYNAME] semodule -i POLICYNAME.pp
To resolve the issue, create a custom SELinux policy with Audit2allow:
Connect to the Deep Security Agent as a root user.
Run the following commands to create a custom policy that will allow access to Deep Security Agent files:
grep ds_agent /var/log/audit/audit\* | audit2allow -M ds_agent
semodule -i ds_agent.pp
Restart the ds_agent.
Check the system messages and confirm that there are no alerts related to ds_agent.
cat /var/log/messages | grep ds_agent
If alerts are still occurring, run the commands from step 2 again. This will update the existing policy and re-apply it.
To remove the SELinux policy, use the following command:
semodule -r ds_agent.
