Network security management allows an administrator to manage a network consisting of physical and virtual firewalls from one central location. Administrators need network security management solutions to get a high level of visibility into network behavior, automate device configuration, enforce global policies, view firewall traffic, generate reports, and provide a single management interface for physical and virtual systems.
Problems Network Security Management Address
In today’s complex network architecture and constantly changing threat environment, it is challenging for IT staff to maintain an effective security posture. Security administrative tasks include supporting an ever-expanding matrix of users, devices, locations, and applications; adhering to compliance; enabling new services; optimizing performance; ensuring access controls and security mechanisms; and troubleshooting on demand. Any misconfiguration can make the network vulnerable to sophisticated threats and regulatory noncompliance.
To confront these challenges, network administrators need to consistently deploy security policies across their network. However, the network infrastructure might have thousands of firewall policies that have accumulated over the years. Often these rules are cluttered, duplicated, outdated, or conflict with new rules, inadvertently affecting a network’s performance and security.
How Does Network Security Management Work?
Network security management provides complete visibility into the network and generates data for assets (asset groupings and classifications), firewalls, applications, ports, protocols, VPNs, NAT, and security policies and vendor devices. This information drills into the details for individual devices and is analyzed. The data is translated into intelligence that decrypts security transactions into manageable, actionable information in the form of policy creation. Updated policies are distributed to enforcement points (firewalls), ensuring network protection.
