Merion Academy・5 minutes read
Hackers in Hollywood movies are often shown using a black screen terminal to hack into systems, a portrayal stemming from the early days of computing. Telnet, while allowing remote connections, is outdated and insecure, with Secure Shell (SSH) being a safer alternative encrypting all data for remote administration and file transfer.
Insights
- Hollywood films often misrepresent hacking by showing hackers typing commands on a black screen, known as a terminal, which was an early interface for computers.
- The Telnet protocol, while allowing remote connections to network devices, is outdated and insecure compared to Secure Shell (SSH), which encrypts all data and commands for secure remote administration and file transfer.
