“SSH is a secure replacement for telnet, rlogin, other
r* and ftp protocols which handle sensitive information in an
unsecure manner. Telnet broadcasts sensitive information such as
usernames and passwords unencrpyted whereas SSH encrypts them, so
that a malicious user trying to retrieve them with a, i.e. some
sniffer could have no use for them as such. Not only telnet is
vulnerable to eavesdropping, many other network services behave in
such unsecure manner. SSH stands for Secure Shell, and is the best
solution so far for these. All those services (telnet, rlogin and
such) are a menace for security of your systems, so if you’re still
using them, well… stop! Use SSH. Not sure nor convinced? Read on.Imagine a situation where your network has a sniffer installed,
without your knowledge, and you’re using telnet (yes, I’m really
trying to make you ditch that telnet service:)). You have a large
network, a lot of sensitive information travels through it, many
mission critical jobs depend on it. You’re the admin, the entire
system is in your hands, yes you have the power… So, you telnet
to it, do some minor modifications, fiddle around the system and
etc, and logout. Tomorrow, an almost nuclear holocaust happens,
your network has been taken over. How come, you had a state of the
art firewall, your system was patched regularly and had a flawless
setup? Your almighty root password has been restored from the logs
a sniffer caught while sniffing the network. You could have just
handed your password around, just the same.”
