1.6-system security

1. Encryption

   • scrambling data to make it unreadable, to add to security in transmitting the data. the receiver can then decrypt the scrambled data to reveal the actual data.

2. Brute force attacks

   • When a person tries to access a network by cracking the login details. done through the process of trial and error, by using automated software
     • Having a limit on how many times you can try a password, can help avoid anyone hacking your details.

3. DDOS

   • This is a type of threat designee to flood a network with useless network traffic. this will make it run slowly or grind to halt altogether. often threat carried out on a web server to take down a website.

4. Data interception and theft

   • when data packets are monitored that are travelling around a network. monitored to see if any personal data. These are called packet sniffers.
     • Using a VPN to send perosonal and sensitive data can deter packet sniffers, from being able to analyse any data.

5. SQL injection

   • Structured Query Language. language used to read data in a database. Is used to search through many records in a database.

6. Penetration Testing

   • Team of people simulate potential attacks, penetration testing can be carried out manually by individuals who carry out attacks.

7. Network forensics

   • Network forensics is carried out on a computer to find out the cause of the network attack, stored data is analysed to find source of attack.

8. Network policies

   • Regular testing of the system to find any vulnerabilities . Regular updating of system. limiting access of data
