What is IT Security?
IT security refers to the practice of protecting information technology systems, networks, and data from unauthorized access, breaches, and other cyber threats. This involves implementing measures such as firewalls, encryption, antivirus software, intrusion detection systems, and access controls to safeguard the integrity, confidentiality, and availability of information. IT security aims to prevent, detect, and respond to cyber-attacks, ensuring that critical data and systems remain secure and operational. It encompasses a wide range of activities, including risk assessment, vulnerability management, incident response, and compliance with security policies and regulations.
