- Updated Software: Regularly check if your operating system, antivirus, firewall, and other software are up to date. Most security updates fix vulnerabilities that hackers might exploit.
- Antivirus and Security Software: Ensure you have reputable antivirus and security software installed and running. Regularly scan your system for malware, viruses, and other malicious software.
- Firewall Protection: Confirm that your firewall is enabled. Firewalls act as a barrier between your computer and unauthorized access, controlling incoming and outgoing network traffic.
- Strong Passwords and Multi-factor Authentication: Use strong, unique passwords for all accounts and enable multi-factor authentication whenever possible. This adds an extra layer of security by requiring a second form of verification.
- Safe Browsing Habits: Be cautious when clicking on links or downloading attachments from unknown or suspicious sources. Ensure websites you visit have HTTPS encryption and look for security indicators like padlock icons in the browser’s address bar.
- Regular Backups: Back up your important files and data regularly. In the event of a security breach or data loss, having backups can help restore your information.
- No Unexpected Behavior: Watch out for unexpected behavior on your computer, such as sudden slowdowns, pop-up ads, unauthorized changes in settings, or unknown software installations. These can be signs of malware or unauthorized access.
- Privacy Settings and Permissions: Review and manage the privacy settings and permissions of your applications, devices, and online accounts. Limit access to sensitive information whenever possible.
- Security Alerts and Warnings: Pay attention to security alerts or warnings from your antivirus software, operating system, or browser. These notifications often indicate potential security threats that need attention.
- Security Audits and Scans: Conduct periodic security audits or scans of your system using reputable cybersecurity tools to check for vulnerabilities and potential threats.
