Arvutiturvalisus

Arvutiturvalisus, also known as cybersecurity, refers to the practice of protecting computers, servers, mobile devices, electronic systems, networks, and data from digital attacks. These attacks are usually aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes. Cybersecurity involves a combination of technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, damage, or unauthorized access.

The primary goals of arvutiturvalisus are to ensure the confidentiality, integrity, and availability of information. Confidentiality ensures that data is accessible only to those authorized to have access. Integrity ensures that data is accurate and trustworthy over its entire lifecycle. Availability ensures that authorized users have access to information and associated assets when required.

Key components of arvutiturvalisus include:

1. Firewalls: These are network security systems that monitor and control incoming and outgoing network traffic based on predetermined security rules.

2. Encryption: This is the process of converting information or data into a code to prevent unauthorized access.

3. Antivirus and anti-malware software: These programs detect, prevent, and remove malicious software that can harm computers and networks.

4. Intrusion detection and prevention systems: These systems monitor network and system activities for malicious activities or policy violations and take appropriate action to prevent them.

5. Security policies and procedures: These are guidelines that outline how an organization should handle sensitive data and protect its systems from cyber threats.

Arvutiturvalisus is a critical aspect of modern life, as our reliance on digital technologies continues to grow. It is essential for individuals, businesses, and governments to implement robust cybersecurity measures to protect against the ever-evolving threats in the digital landscape.
