What is Network Security?

  • Firewalls prevent unauthorized users from accessing the network by allowing or denying traffic.
  • Anti-Virus/Malware software protects network endpoints and servers from becoming infected by damaging software that can corrupt files, export sensitive data, or perform other malicious activities.
  • Application Security systems look for and block vulnerability points in application software.
  • Network Access Control systems manage access permissions for authorized users and devices, preventing unauthorized users from gaining access.
  • User Behavior Analytics solutions monitor user activity, baseline normal behavior, and alert on activities that deviate from normal activity.
  • Network Traffic Analysis: Network Detection and Response (NTA/NDR) products analyze network traffic, look for abnormal patterns that can indicate attacks, and take action based on the results. Network traffic does not lie and contains strategic data for threat detection.
  • Cloud Security solutions protect resources in the cloud.
  • Intrusion Prevention Systems (IPS) monitor for and block attacks from outside users or processes that get past the firewall.
  • Security Information and Event Management (SIEM) products collect data from various device logs on the network and can monitor for anomalies. Traffic-based NTA/NDR products complement SIEMs by analyzing logs and taking action. In fact, NTA/NDR is critical to advancing visibility beyond logs.
