Firewalls are like the security guards of a network—they monitor and control incoming and outgoing traffic based on predefined security rules. Their main job is to protect your network from unauthorized access, cyberattacks, and data breaches. 

Passwords should be changed in these situations:

1. After a Security Breach – If a service you use has been hacked or your account shows signs of suspicious activity.

2. If You’ve Shared It by Mistake – Even with someone you trust, it’s safer to reset.

3. When Using Weak or Old Passwords – Replace them with strong, unique ones.

4. If You Reuse Passwords – Each account should have its own password.

5. After Using a Public/Untrusted Device – In case login details were captured.

6. As Part of a Security Policy – Some workplaces require regular changes (e.g., every 60–90 days).

Tip: Instead of changing passwords on a strict schedule, focus on using strong, unique passwords and enabling multi-factor authentication — this provides stronger protection than frequent but weak changes.
