BPFDoor malware has emerged as a serious threat to Linux systems, designed with sophisticated techniques that allow it to operate undetected. This malware leverages Berkeley Packet Filtering (BPF) to sneak past firewalls and inspect network packets for specific sequences, effectively hiding its presence.

We Linux security admins are always searching for the latest insights to help us secure our systems against current and emerging threats. A recent TuxCare report on open-source security risks and trends shares some crucial insights that open-source community members and Linux security admins should be aware of.

As Kubernetes and cloud-native technologies become increasingly integral to IT infrastructures, we Linux security admins must adapt to a rapidly changing environment where agility and security converge. A recent CNCF survey highlights a significant uptick in Kubernetes deployment, with most organizations using container technology as a backbone for their applications.

Secure remote connections are essential when managing a Linux server, and one of the most widely used and trusted methods for remote server administration is Secure Shell (SSH) . SSH creates a protected channel over an insecure network by encrypting all information shared between the server and client, safeguarding data exchanged between them from potential attackers, eavesdroppers, hijackers, or manipulators of communication streams.
