SELinux and AppArmor are supported on the distributions where they are present by default. ESET Server Security for Linux runs under the default context obtained from the system. |
|
The latest Linux kernel for Ubuntu Server 22.04 requires gcc-12 for kernel modules compilation. See our Knowledgebase article for more information on this issue. |
|
Linux distributions with ELREPO kernel and cloud kernels are not supported. RHEL with the "Protection Profile for General Purpose Operating Systems (OSPP)" is not supported. |

1 s3fs communicates over HTTP, which may trigger Web access protection (WAP) instead of Real-time file system protection (RTP). This can cause infected files to be blocked by WAP instead of RTP, and files are not cleaned. Therefore, s3fs is excluded from WAP by default.
