1.6 system security V2

1. forms of attack

   • phishing
   • people as the weak point in secure system (social engineering)
   • brute force attacks
   • DDOS
   • Data interception and theft
   • SQL injection
   • poor network policy

2. preventing vunerability

   • penetration testing
   • network forensics
   • network policies
   • anti-malware software

3. user access levels

4. passwords

5. encryption

6. malware
