7. Security Tips
- Use strong passwords: Complex passwords with a combination of uppercase, lowercase, numbers, and symbols enhance security.
- Enable two-factor authentication (2FA): Adds an extra layer of security by requiring a code sent to your mobile device.
- Keep software up to date: Regular software updates patch security vulnerabilities.
| Security Measure | Description | Benefits | |---|---|---| | Strong Passwords | Complex passwords improve account security | Reduces the risk of unauthorized access | | Two-Factor Authentication | Requires additional authentication beyond the password | Prevents attackers from accessing accounts even with stolen passwords | | Software Updates | Patches security loopholes | Mitigates vulnerabilities and protects against exploits | | Firewalls | Network security systems that block unauthorized access | Prevents external threats from accessing the server | | Intrusion Detection Systems (IDS) | Monitors network traffic for suspicious activity | Detects and alerts on potential security breaches |
