System Security Prevention

System Security Prevention

1. Network policies

   • Disaster Recovery Policy
   • Acceptable Use Policy (complex passwords)
   • Backup Policy

2. Penetration Testing

   • A company will invite/employ experts to try a range of attacks on their network. This is used to discover vulnerabilities.

3. Network Forensics

   • Networks should have software which continuously monitors network traffic.
   • Can find out how an attack was carried out and who did it.

4. Anti-Virus Software

   • Locates and destroys malicious files.

5. Firewall

   • Monitors what data is being sent and received. Only opens ports at certain times to allow data in and prevent viruses.

6. Encryption

   • Encryption is where data is scrambled before being sent across a network so if it is intercepted it cannot be understood.

7. Anti-Spyware Software

   • Spyware tracks your information and sends it back. keylogger tracks what keys the user clicks so usernames,passwords,websites they visit etc are sent back.
