informatsiooniohutus

Informatsiooniohutus, also known as information security or infosecurity, refers to the practice of protecting information from unauthorized access, use, disclosure, disruption, modification, or destruction. It encompasses a broad range of measures and practices aimed at ensuring the confidentiality, integrity, and availability of data. Confidentiality means that information is accessible only to authorized individuals. Integrity ensures that information is accurate, complete, and has not been altered without authorization. Availability means that authorized users can access information when they need it.

The field of informatsiooniohutus is critical in today's digital world, where vast amounts of sensitive data are stored and transmitted electronically. Threats to information security can originate from various sources, including malicious actors such as hackers, cybercriminals, and insider threats, as well as accidental data breaches or system failures. These threats can lead to significant consequences, including financial losses, reputational damage, legal liabilities, and disruption of business operations.

To mitigate these risks, informatsiooniohutus employs a multi-layered approach. This includes technical measures like firewalls, antivirus software, encryption, and intrusion detection systems. It also involves administrative controls such as security policies, access controls, employee training, and risk management procedures. Physical security measures, such as securing data centers and restricting access to sensitive areas, are also an integral part of a comprehensive informatsiooniohutus strategy. The ongoing evolution of threats necessitates continuous adaptation and improvement of security practices to stay ahead of emerging challenges.
