Verkkosuojauksia, often translated as network security, refers to the practices and technologies implemented to protect computer networks and data from unauthorized access, use, disclosure, disruption, modification, or destruction. The primary goal is to ensure the confidentiality, integrity, and availability of network resources. This involves a multi-layered approach, addressing various potential threats and vulnerabilities.

Key components of network security include firewalls, which act as barriers between internal and external networks, controlling incoming and outgoing traffic based on predefined security rules. Intrusion detection systems (IDS) and intrusion prevention systems (IPS) monitor network traffic for malicious activity or policy violations, alerting administrators or actively blocking threats. Antivirus and anti-malware software are essential for detecting and removing harmful software that can compromise network security.

Encryption plays a crucial role by transforming data into an unreadable format, ensuring that even if intercepted, sensitive information remains protected. Virtual private networks (VPNs) establish secure, encrypted connections over public networks, allowing remote users to access internal resources safely. Strong authentication methods, such as complex passwords, multi-factor authentication, and access control lists, are implemented to verify the identity of users and devices before granting access to network resources. Regular security audits, vulnerability assessments, and employee training on security best practices are also vital for maintaining a robust network defense.
