Understanding Computer Security Measures
In the context of improving computer security, there are several measures that individuals and organizations can take. Let's evaluate the options provided:
- Installing antivirus and antispyware software - This is a vital measure in protecting computers from malware and harmful software.
- Leaving computers unlocked and unattended - This is NOT a security measure. In fact, it poses a significant risk as anyone can access sensitive information when a computer is left unsecured.
- Regularly updating operating systems - Keeping software up-to-date is critical for fixing vulnerabilities that attackers could exploit.
- Using e-mail security features - Implementing security features such as encryption and spam filters is essential to protect against phishing and unauthorized access.
