By Dipali Umre

  1. Keeps Bad Guys Out:
    • The firewall is like a gatekeeper for your network, stopping unauthorized users (the bad guys) from getting in.
  2. Blocks Risky Stuff:
    • It prevents potentially risky services from entering or leaving your network. It’s like saying “no” to activities that could be harmful.
  3. Stops Tricks:
    • Protects against tricks like IP spoofing (faking identity) and routing attacks (messing with the network paths).
  4. Makes Security Easy:
    • It’s like having one boss (the firewall) to manage security. Everything is in one place, making it simpler.
  5. Watches Everything:
    • Acts like a security camera. It keeps an eye on events, so if something fishy happens, alarms can go off.
  6. Does Extra Jobs:
    • Apart from security, it also does other useful tasks like translating local addresses to internet addresses and managing network usage.
  7. Private Network Guardian:
    • It can create virtual private networks, like a secret tunnel for safe communication, which is great for keeping things private.
