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. 

Encryption is the process of converting plain, readable data into an unreadable format to protect it from unauthorized access. It ensures that only authorized parties can access or understand the original information.

The frequency with which passwords should be changed depends on context, risk level, and industry guidelines. Here's a general guideline:

1. For Most Users (Low to Medium Risk):

  • Only change passwords when:

    • You suspect a breach or phishing attempt.

    • You’ve reused the same password across multiple sites.

    • The password is weak or outdated.

This approach aligns with modern security best practices (e.g., NIST guidelines), which discourage frequent password changes unless there's a specific reason—because users tend to create weaker or reused passwords when forced to change them too often.

2. For High-Risk Environments (e.g., Financial, Government, Healthcare):

  • Change passwords every 60 to 90 days if:

    • No multi-factor authentication (MFA) is used.

    • You handle sensitive or regulated data.

3. Best Practices Regardless of Frequency:

  • Use strong, unique passwords.

  • Enable Multi-Factor Authentication (MFA).

  • Use a password manager to store and generate secure passwords.

  • Monitor for data breaches
