Network Security / Network Security

Network security or network security refers to the measures taken to protect computer networks and communication systems against threats.

Network security includes various technological and managerial measures to ensure the confidentiality, integrity and accessibility of data located in computer networks.

  • Network Security / Network Security

    • Firewall: Firewall is a security measure that controls traffic entering and leaving the network. A well-configured firewall increases the security of the network by blocking unauthorized access attempts.
    • Network Access Control (NAC): NAC is a policy-based approach used to secure devices connected to the network. NAC checks the authentication and security compliance of devices connected to the network and prevents unauthorized devices from accessing the network.
    • Virtual Private Network (VPN): VPN allows remote access users to connect to the network securely. VPN ensures that data is transmitted securely by encrypting and that users' real IP addresses are hidden.
    • Intrusion Detection and Prevention Systems (IDPS): IDPS are systems that detect and prevent anomalies and attack attempts on the network. IDPS protects against attacks on the network using known attack signatures or behavioral analysis techniques.
    • Network Encryption: Encrypting data on the network ensures that data is transmitted securely. Encryption ensures the confidentiality of data by providing protection from unauthorized access.
    • Regular Updates: It is important to update network devices and software regularly. Security patches and updates provided by the manufacturer fix known vulnerabilities and increase the security of the network.
    • Strong Authentication and Authorization: It is important to authenticate and authorize users accessing the network. Measures such as strong passwords, multi-factor authentication methods (for example, two-factor authentication), access control lists, and user authorization policies should be used.
    • Training and Awareness: Raising awareness and training of employees and network users about network security is important. Security awareness should be provided to users in order to recognize and prevent attacks carried out through methods such as social engineering attacks, malicious e-mails or phishing.
    • Monitoring and Logging: Monitoring and logging events on the network is important for detecting attacks and troubleshooting problems. Logging all activity on the network enables retrospective analysis of events and can help identify the origin of attacks.
