- The
pkg-mgr-executionintent likely aims to prevent unauthorized or potentially harmful package management operations. This is critical in a Kubernetes environment, where package managers can be exploited by adversaries to install malicious software or manipulate existing applications.
Note : For the exploit-pfa intent one needs to have nimbus-kubearmor adapter running in their cluster. To install the complete suite with all the adapters pls follow the steps mentioned here
The exploit-pfa intent results in KubeArmorPolicy. Below is the behaviour of intent in terms of policy:
- For the
KubeArmorPolicyto work, one should have a BPF-LSM enabled for each node in their cluster.
-
The KubeArmorPolicy created here specifies that any attempt to execute certain package management commands will be blocked. This is a proactive security measure to prevent unauthorized changes to the system.
-
By blocking execution of these critical pkg-mgmt tools, the policy significantly reduces the attack surface for the application. This prevents attackers from executing potentially malicious scripts or binaries that could lead to data breaches or further compromises.
