Secure Remote Access Methods

Remote access lets administrators and users connect to and manage systems from a distance. It is essential for IT work and remote employment, but it is also a prime target, since any door into your network can be attacked.

The goal is to enable convenient remote work while keeping those access methods locked down against intruders.

SSH (Secure Shell) is the standard for securely managing servers and network devices remotely over an encrypted channel, using TCP port 22. It replaced the old, dangerous Telnet.

SSH encrypts everything, including the login, so credentials and commands cannot be sniffed. It can also use key-based authentication, which is stronger and more convenient than passwords.
