IT Security, also known as cybersecurity, involves the practices, technologies, and policies designed to protect networks, computers, programs, and data from attack, damage, or unauthorized access. In today's digital age, IT security is critical for protecting the information assets of both organizations and individuals. It encompasses a wide range of areas, including network security, application security, endpoint security, data security, identity management, and disaster recovery/business continuity planning. The aim of IT security is to ensure the confidentiality, integrity, and availability of data (often referred to as the CIA triad). With the increasing frequency and sophistication of cyber threats, IT security strategies and measures are constantly evolving to defend against malware, defend against ransomware, defend against phishing, and defend against advanced persistent threats (APTs). Implementing robust IT security measures is essential for preventing data breaches, safeguarding against financial losses, and protecting the reputation of organizations.
