Field techs still use Telnet to the city’s outdoor AP CLI. What preventative change should security mandate?
Select an answer to reveal the explanation.
Short Explanation
Telnet is a postcard; SSH is a sealed envelope. For AP CLI work on city gear, seal the envelope and retire the postcard—banners do not encrypt keystrokes.
Full Explanation
Telnet transmits administrative sessions in cleartext and should be disabled on WLAN infrastructure. SSH provides encrypted CLI administration and is the appropriate replacement. Protocol gymnastics, banners alone, or publishing credentials do not constitute preventative hardening.
