Cybersecurity refers to the practice of safeguarding computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. It is also known as information technology security or electronic information security and is essential in various contexts, from business to mobile computing. Cybersecurity can be categorized into several key areas:
The scale of the cyber threat is continuously evolving, with an increasing number of data breaches occurring each year. Global spending on cybersecurity solutions has also been rising as a response to the escalating threats. Various governments, including the US, UK, and Australia, have provided guidance and frameworks to help organizations implement effective cybersecurity practices.
Cyber threats come in various forms, including cybercrime, cyber-attacks, and cyberterrorism. Malicious actors use different methods to gain control of computer systems, such as employing malware (viruses, trojans, spyware, ransomware, etc.), conducting SQL injection attacks, carrying out phishing scams, performing man-in-the-middle attacks, and initiating denial-of-service attacks.
To protect against cyber threats, end-user protection or endpoint security is crucial. This involves encrypting sensitive data, using security software to scan and remove malware, and employing real-time malware detection with heuristic and behavioural analysis. Regular software updates, strong passwords, and cautious behaviour, such as avoiding unknown email attachments and unsecured public Wi-Fi networks, are also important cyber safety tips for individuals and businesses.
