Protection of data

Protection of data

1. Physical barriers

   • Real world protection such as locks on doors, CCTV cameras and turning computers off at night

2. Password control of access

   • Using strong passwords that are at least eight characters long and include at least one uppercase letter, lowercase letter, number and symbol

3. Access levels

   • Ensuring people only have access to the parts of the system they need and training them before giving them greater access

4. Anti-virus software

   • Software that deletes or quarantines viruses

5. Firewall

   • Software that monitors data coming in and out of a network and protects it from viruses, malware and hackers. It puts a 'wall' around the network

6. Encryption

   • Turning data into a secret code before sending it over a network or the internet, so that if it is intercepted it will not be understood

7. Backup and recovery

   • Making a copy of data in a different place to the original data in case the original becomes corrupt or is accidentally deleted

8. Recovery

   • Replacing the data if something happens, such as deletion or corruption. This may include copying the files from the backup to their original location or using a software recovery tool. In servers, this may involve replacing a damaged drive with a new one already loaded with the backup data

9. Personal safety

   • Security settings can be used on social networking sites to protect users' privacy and reputation
     • This is important as not everyone is who they claim to be. Also, you might not want your teacher or colleague to see something that is embarrassing or harmful to your reputation

10. Identity theft

    • Where someone uses another individual's personal details to pretend they are them. They may set up accounts, access bank accounts or make purchases. This threat can be prevented most effectively by users keeping their personal details private, including on social networking sites
