5.5 - Digital Security

There are many ways people can protect themselves online. These involve digital security measures:

• Anti-Virus: Software used to scan computer systems for potential viruses and either remove or quarantine them, so they no longer pose a threat
• Firewalls: A system that tracks and secures data on a network and blocks potentially dangerous programs from accessing the network. 
• Anti-Spyware: Software that scans a system for spyware and removes it, protecting the system from unauthorised people accessing data.
• Usernames/Passwords: Unique identifiers that prove that you are authorised to access a system.
• Permissions: The levels of authority that show whether people have authorisation to access data.
• Encryption: The process of ciphering data so it cannot be understood without the accurate key.
