As remote server access becomes ubiquitous, SSH host key verification remains a critical yet often overlooked security layer. KnownHosts emerges as a pivotal service, offering centralized trust management to prevent devastating man-in-the-middle attacks.

When firewalls block direct SSH access, the Tor network offers a clever workaround. This guide explains how to establish secure SSH connections through Tor's onion routing, providing both anonymity and a workaround for restrictive network environments.

Discover how SSH configuration files and key-based authentication transform cumbersome remote server management into streamlined, secure workflows. This deep dive explores practical optimizations for developers and sysadmins, from simplifying connections to hardening access protocols.

A meticulously engineered backdoor hidden within the widely used xz compression library was narrowly averted from infiltrating Linux distributions worldwide. This sophisticated attack exploited the trust in open source maintenance and targeted SSH security, revealing critical vulnerabilities in software supply chains.

As threat actors increasingly target developers' SSH keys for infrastructure attacks, touch-verified authentication has evolved from theoretical protection to operational necessity. This deep dive explores how hardware-backed solutions like FIDO2 keys and Apple's Secure Enclave create an immutable security layer against credential theft.

Managing multiple SSH tunnels just got simpler with tunn, a new Go-based utility that replaces cumbersome command-line arguments with declarative YAML configurations. This open-source tool enables parallel tunnel execution, daemon mode, and granular control while leveraging existing OpenSSH configurations—streamlining secure connections for databases, APIs, and microservices.
