Tips and Tricks to Enhance Computer Security

Use Strong and Unique Passwords

One of the most basic and vital computer security practices is to create strong, unique passwords for each online account. Your passwords should be a mix of letters, numbers, and special characters.

Make sure all the software on your system including the operating system, web browsers, apps, and anti-virus programs are always up-to-date. Software updates often include patches for security issues.

Install a Reliable Antivirus

Antivirus software can provide an additional layer of protection by detecting and removing malicious software. Antivirus programs can also detect phishing attempts and warn users about suspicious websites.

Encrypt Your Data

Data encryption transforms data into a coded form, making it harder for hackers to access it. You can encrypt your data with built in features in your operating system like BitLocker in Windows or FileVault in macOS.

Regular Backup

Even with the best computer security measures, data loss can still occur due to hardware failure, natural disasters, or other unexpected events. Regularly backing up data ensures that it can be recovered in the event of such issues.
