Spyware, ransomware and viruses
When is malware installed on a person’s device?

What is social engineering?
Social Engineering is a way of gaining sensitive information or illegal access to networks by influencing people e.g., employees in large companies

What is anti malware?
Anti-Malware software is designed to find and stop malware from damaging a network and devices on it. Anti-virus is a type of anti- malware
What do firewalls do?
Firewalls examine all data entering
and leaving the network and block any potential threats.
What do user access levels do?
User Access Levels control which part of the network different groups of users can access. This limits the number of people with access to important data.
What do passwords do?
Passwords help prevent unauthorised users from accessing the network. Passwords should be strong and changed regularly.
What is encryption?
Encryption is when data is translated into a code which only someone with the correct key can access. Encrypted text is called ‘cipher text’.
