Precautions for maintaining system performance and integrity and maintaining data security include firewalls, software for detecting and disabling malicious programs or malware and e-mail filtering software (spam filters).

Precautions for maintaining user safety include content filtering, proxy servers, monitoring and reporting user behaviour and withholding personal information. It’s also important to use non-trivial usernames and passwords. These issues are covered in the next section of this course: Safeguarding Yourself and Others.
