What is Cyber Security Threats?
Within Computer Science, which covers algorithms, programming, data, networks, hardware and safe, responsible use of technology, this topic explains Cyber Security Threats. Computing topics explain how software, hardware and data work, with diagrams and models that show each step in order.
Check that you can explain Cyber Security Threats in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Cyber Security Threats helps you design, test and explain programs, websites and systems, from small projects to exam questions.
Cyber Security Threats in detail
Cyber security protects systems and data from attack. Threats include malware (viruses, worms, trojans, ransomware and spyware), phishing (fake emails or sites that trick people into giving information), social engineering, brute-force attacks (guessing passwords), denial-of-service attacks (flooding a server) and SQL injection.
Weak passwords, unpatched software, public Wi-Fi and human error make attacks easier. Effects include data theft, financial loss, disruption and loss of trust. Defences combine technology (firewalls, antivirus, updates) and people (training, caution). Understanding the threats helps you recognise and avoid them.
