Unlocking SSH Security: Navigating Vulnerabilities and Best Practices in Remote Access Protocols
In the ever-evolving realm of cybersecurity, the use of SSH (Secure Shell) remains a fundamental tool for secure remote access to servers. However, recent discussions and experiments by developers and system administrators have shed light on the potential vulnerabilities and challenges associated with SSH security protocols.
One of the key concerns raised is the prospect of enabling SSH features on a per-address basis by default, particularly in the context of IPv4 and the increasing deployment of Carrier-Grade Network Address Translation (CGNAT). This raises the possibility of innocent bystanders being penalized, or worse, malicious actors locking out legitimate server owners if they have a botnet host within the same network.
