Cybersecurity, also referred to as computer security, is a specialized area focused on the protection of computer systems, networks, and data against digital threats. The objective of these threats is often to gain unauthorized access, modify, or destroy sensitive data, disrupt regular business operations, or take advantage of system weaknesses for harmful intents. Cyber threats and attacks can take on many forms, including malware, phishing, and denial-of-service attacks, among others. To counteract these threats, security strategies such as secure coding, access control, firewalls, and hardware protection are implemented. Given the ever-changing landscape of cyber threats, it’s crucial to regularly update these security strategies. The data and trends in this sector highlight the significance of implementing strong cybersecurity measures to avoid potentially expensive and damaging security breaches.

Computer security (Wikipedia)

Computer security, cybersecurity, digital security or information technology security (IT security) is the protection of computer systems and networks from attacks by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide.

An example of physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering.

The field is significant due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi. It is also significant due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, elections, and finance.

While most aspects of computer security involve digital measures such as electronic passwords and encryption, physical security measures such as metal locks are still used to prevent unauthorized tampering.
