What is Cyber Security & IT Laws?
Cyber Security & IT Laws is a subject that focuses on protecting computers, networks, applications, digital information, and users from cyber threats while understanding the legal rules governing the use of information technology. Cyber security covers concepts such as confidentiality, integrity, availability (CIA Triad), authentication, authorization, cryptography, network security, application security, ethical hacking, and digital forensics. IT laws deal with cyber crimes, data protection, privacy, digital signatures, intellectual property, and legal responsibilities in the digital environment.
