Infoturvasüsteemid, commonly referred to as information security systems, are a broad category of technologies, processes, and policies designed to protect digital information and computer systems from unauthorized access, use, disclosure, disruption, modification, or destruction. The primary goal is to ensure the confidentiality, integrity, and availability of information, often summarized as the CIA triad. Confidentiality ensures that data is only accessible to authorized individuals. Integrity guarantees that data is accurate and has not been tampered with. Availability ensures that systems and data are accessible to authorized users when needed.

These systems encompass a wide range of solutions. Network security measures, such as firewalls and intrusion detection systems, protect the perimeter of a network. Endpoint security, including antivirus software and endpoint detection and response (EDR) solutions, safeguards individual devices. Data security measures focus on protecting data both at rest and in transit, often employing encryption. Identity and access management (IAM) systems control who can access specific resources and what actions they can perform. Security information and event management (SIEM) systems collect and analyze security logs to detect and respond to threats.

The implementation of effective information security systems requires a layered approach. This involves combining technical controls with administrative policies and physical security measures. Regular security audits, vulnerability assessments, and employee training are crucial components of a robust security program. As threats evolve, information security systems must adapt to counter new risks, including sophisticated cyberattacks, malware, phishing, and insider threats. Maintaining a strong information security posture is essential for individuals, organizations, and governments to protect sensitive data and maintain trust.
