Password protection

Password protection is a critical aspect of computer security. Passwords serve as a primary means of securing access to systems, applications, and sensitive data. However, passwords are also one of the weakest links in the security chain. Weak passwords can be easily guessed or cracked, and they can be stolen through phishing attacks or other means.

1. Password Complexity​

Ensure that passwords are complex and difficult to guess. Follow these guidelines:

  • Length: Use long passwords. Aim for at least 12 characters or more.
  • Mix Characters: Include a combination of uppercase letters, lowercase letters, numbers, and special symbols.
  • Avoid Common Words: Avoid using common words, phrases, or easily guessable information like birthdays, names, or dictionary words.

Example of a strong password: P@$$w0rd!123

2. Unique Passwords​

Use unique passwords for each account or service. Reusing passwords across multiple accounts increases the risk of a security breach. Consider using a password manager to help generate and store unique passwords securely.

3. Password Rotation​

Regularly change passwords, especially for critical accounts. Passwords should be rotated at least every three to six months. Some systems may enforce password expiration policies.

4. Two-Factor Authentication (2FA)​

Enable two-factor authentication wherever possible. 2FA adds an additional layer of security by requiring users to provide a second form of authentication, such as a temporary code sent to their mobile device, in addition to their password.

5. Avoid Sharing Passwords​

Never share passwords through email, chat, or any other unsecured communication channel. If you need to share access, use a secure method and change the password afterward.

6. Password Storage​

Do not store passwords in plain text. Passwords should be securely hashed and salted before storage. Use established password hashing algorithms like bcrypt or Argon2.

7. Secure Password Reset​

Implement a secure password reset process that verifies the user's identity through multiple factors before allowing password changes.

8. Account Lockout​

Implement account lockout policies to protect against brute-force attacks. After a specified number of failed login attempts, temporarily lock the account to prevent further attempts.

9. Education and Training​

Educate users about password security best practices. Regularly conduct training sessions to raise awareness about the importance of strong passwords and the risks of sharing them.

10. Regular Auditing​

Perform regular security audits to identify weak passwords, unauthorized access attempts, and suspicious activities. Act promptly to address any security issues.

11. Password Policy​

Establish and enforce a password policy within your organization. This policy should define password complexity requirements, expiration rules, and other security-related guidelines.

12. Multi-Step Verification​

Consider implementing multi-step or multi-factor verification for sensitive accounts and systems. This includes not only 2FA but also additional security checks like behavioral biometrics.

13. Periodic Review​

Regularly review and update your password protection practices and policies to adapt to changing security threats and technologies.

14. Encryption​

Ensure that passwords are transmitted securely, especially when users log in or change their passwords. Use HTTPS and secure protocols for these operations.

15. Monitor for Security Breaches​

Implement security monitoring tools and procedures to detect and respond to security breaches promptly.
