Linux systems as well as Open Source solutions are the backbone of the modern Internet, critical services, and services. Kubernetes clusters, containers, complex business applications and APIs, corporate firewalls, gateways, load balancers and jump hosts, proxy and WAF servers, NIDS, and NIPS systems. CI/CD. C2 servers and redirectors as well. When referring to the above solutions and services, I always automatically see Linux. Linux for defense and attack.
Awareness of threats in the above context suggests that their low-level monitoring, tracing, configuration hardening, periodic examination of behavior profiles including the RAM memory forensics process, or proactive hunting for threats are areas that are worth developing in order to minimize the risk and impact of a potential attack. Such an approach increases the chances of an attack being prevented or detected early in the chain, thus gaining contextual insight into post-exploitation activities at multiple layers. In the above context, we will refer to the eBPF technology in the offensive-defensive approach.
