System Security 1.6

System Security 1.6

1. Different forms of attacks

   • Malware
   • Phishing
   • Brute force
   • Denial of service
   • Data interception and theft
   • SQL injection
   • People as the weak point in secure systems (social engineering)

2. Forms of attack Threats posed to networks: Malware Phishing People as the weak point in secure systems (social engineering) Brute force attacks DDOS Data interception and theft SQL injection Poor network policy

3. Identifying and preventing vulnerabilities: Penetration testing, Network forensics, Network policies, Anti-malware software, Firewalls, User access levels, Passwords Encryption

4. key words

   • Malware
   • Viruses
   • Worms
   • Trojan Horses
   • Phishing
   • Social Engineering
   • Data Interception
   • Network Policies

5. Malware

   • Otherwise known as ‘malicious software’ Software which can be malicious if damaging to a computer or network Examples include viruses, worms and Trojan horses

6. Viruses

   • Malicious software designed to cause harm to a network or computer system Attaches itself to programs or files on a computer or server Can affect all components of an operating system Around 82,000 viruses are made each day

7. Worms

   • Replicates itself in order to spread to other computers Often using a computer network In order to achieve this, the worm exploits vulnerabilities across the computer network Unlike a virus, it does not need to attach to a program

8. Trojan Horses

   • Replicates itself in order to spread to other computers Often using a computer network In order to achieve this, the worm exploits vulnerabilities across the computer network Unlike a virus, it does not need to attach to a program

9. Social Engineering

   • Relies on human interaction (social skills) Commonly involves tricking users into breaking normal security procedures Method does not revolve around technical cracking techniques such as worms or viruses
