Isai 78d6093176 [New Rule] Kubernetes Container Created with Excessive Linux Capabilites (#2313)
* [New Rule] Kubernetes Container Created with Excessive Linux Capabilites

This rule detects a container deployed with one or more dangerously permissive Linux capabilities. Using the Linux capabilities feature you can grant certain privileges to a process without granting all the privileges of the root user. Added capabilities entitle containers in a pod with additional privileges that can be used to change core processes and networking settings of a cluster. An attacker with the ability to deploy a container with added capabilities could use this for further execution, lateral movement, or privilege escalation within a cluster or the host machine. This rule detects the following capabilities and leaves space for the exception of trusted permissive containers specific to your environment:

BPF - Allow creating BPF maps, loading BPF Type Format (BTF) data, retrieve JITed code of BPF programs, and more.

DAC_READ_SEARCH - Bypass file read permission checks and directory read and execute permission checks.

NET_ADMIN - Perform various network-related operations.

SYS_ADMIN - Perform a range of system administration operations.

SYS_BOOT - Use reboot(2) and kexec_load(2), reboot and load a new kernel for later execution.

SYS_MODULE - Load and unload kernel modules.

SYS_PTRACE - Trace arbitrary processes using ptrace(2).

SYS_RAWIO - Perform I/O port operations (iopl(2) and ioperm(2)).

SYSLOG - Perform privileged syslog(2) operations.
