What is network security management and how does it work?
Using network security management, an administrator may control a network that is comprised of both physical and virtual firewalls from a single centralized place. Network security management solutions are required by administrators to gain 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 both physical and virtual systems, among other things.
Problems Network Security Management Address
It is difficult for IT personnel to maintain an effective security posture in today’s sophisticated network architecture and continuously changing threat environment. Supporting an ever-expanding matrix of users, devices, locations, and applications; adhering to compliance; enabling new services; improving performance; ensuring access restrictions and security mechanisms, and troubleshooting on demand are all examples of security administration activities. The network can become exposed to sophisticated threats and non-compliance with regulatory requirements if it is misconfigured in any way.
To meet these difficulties, network administrators must ensure that security policies are uniformly applied throughout their network. In contrast, the network architecture may have thousands of firewall policies that have been collected over several years. Frequently, these rules are cluttered, redundant, out of date, or in conflict with new rules, which has an unintended impact on the performance and security of a network.
As an example of a typical enterprise scenario in which the IT department must address network security management, the following diagram is provided:
Through the use of security policy and workflow tools, network security management can help to reduce the number of manual activities and human errors by centralizing administration and providing a centralized management interface.
Through the use of threat information, network vulnerabilities, and the criticality of those vulnerabilities, evaluating potential countermeasures to an attack, and providing intelligence for decision support, network security management can help organizations reduce risk across their networks and protect data.
Improved policy administration is achieved through the unification of common policy chores into a single interface, the automation of policy update workflow, including compliance audits, and the management of numerous firewall vendor relationships. IT teams may save time and money by using this simplified and automated security policy management system. They can also prevent manual errors and reduce risk.
How Does Network Security Management Work?
In addition to generating data for assets (asset groupings and classifications), firewalls, applications, ports, protocols, virtual private networks (VPNs), network-assisted network traffic (NAT), and security rules, network security management also generates data for vendor devices. This data is used to dive down into the specifics of individual devices and is then examined. The data is transformed into intelligence, which decrypts security transactions and transforms them into manageable, actionable information in the form of policy design and implementation. The latest policy updates are transmitted to enforcement points (firewalls), guaranteeing that the network is protected.
