security services in network security

 

Network security services are considered critical services, as they guard the organization's IT infrastructure, data, and systems from threats and unauthorized access. Some of the significant security services in network security are identified to include:

• Firewall Protection: Firewalls monitor and control incoming and outgoing network traffic according to specified security rules. Firewalls are identified to act as a barrier between trusted, internal networks and untrusted, external networks.

• Intrusion Detection and Prevention Systems (IDPS): IDPS is to monitor network traffic for possibly suspicious activity and actual threats. They can alert an administrator (Intrusion Detection) or actually block malicious activity based on rules defined for a given network environment (Intrusion Prevention).

• Virtual Private Networks (VPNs): Secure, encrypted communication over public networks-this enables remote workers or branch offices to connect securely to the corporate network.

• Anti-virus and Anti-malware Solutions: These are the tools used for detecting, preventing, and removing viruses, worms, and other malicious software types that infect devices and spread across the network.

• Access Control: Mechanisms of access control include AAA-Authentication, Authorization, and Accounting. Access is allowed to network resources by only authorized users and devices.

• Encryption Encryption techniques secure the data in motion and at rest, making them unreadable for unauthorized parties. It is of utmost importance in protecting sensitive data, especially over unsecured networks.

• Network Segmentation Dividing the network into segments or zones based on the security needs of the organization can limit access to sensitive data and reduce the potential impact of a breach.

• SIEM: SIEM systems collect and analyze log data from around the network to detect suspicious behavior and furnish a centralized view of security events.

• Threat Intelligence: Threat intelligence services provide information about potential cyber threats, thus helping organizations stay ahead of attackers and understand the tactics, techniques, and procedures used by malicious actors.

• Multi-Factor Authentication (MFA): MFA enhances security by forcing users to give two or more verification factors, such as a password, biometrics, or one-time code, to access a network.
