4 Best Practices for Network Security Management
Today’s IT security teams are faced with rapidly mutating threats at every possible point of entry- from the perimeter to the desktop; from mobile to the cloud. Fueled by the last evolution of the threat landscape and changes in network security architecture, network security management has become far more challenging and complexed.
Security teams must support internal and external compliance mandates, enable new services, optimize performance, ensure availability, and support the ability to troubleshoot efficiently on demand-with no room for error. That’s a lot to balance when managing network security.
Here are four essential best practices for network security management:
1.Network Security Management requires an overview: Organizations need to have a holistic view of their network. With disparate vendor devices and hosts, security teams need a normalized, comprehensive view of the network including: routing rules, access rules, NAT, VPN etc.
With a comprehensive view of the network security teams can view hosts in the network, as well as configurations, classifications and a diagnostic tool providing analysis that is only possible when considering an overall view. For example, security and compliance team can use this micro view to see how data would move between points on network.
2.Daily Device Management requires a Micro View: Although the macro view is needed to see how all pieces of the network fit together, network administrators must also be able to drill down into the details for a particular device, easily accessing information on rules, access policies and configuration compliance.
Information must be provided in a digestible fashion. The network components that impact the device will undoubtedly come from various vendors, creating data of different vendor languages that must be corelated and optimized. Ideally a networking modelling tool that provides a macro view should also allow administrators to drill down into a micro view of each device providing information on users
3.Simulate Attacks for Context- Aware Risks Assessments: Merely knowing the network vulnerabilities and their criticality is insufficient for understanding the true level risk to an organization. Today’s attack incorporates multiple steps that cross several different zones and an isolated view of these steps could appear dangerous for the data stored within the organization.
Attack simulation can also evaluate potential options to block an attack, providing intelligence for support in decision. For example, if an asset runs an application that is crucial to maintain for any business and requires continuous availability, a medium-level vulnerability that threats this asset might be a high-level risk to the particular business.
4. Secure Change Management is Critical: Once a network is in compliance, a secure change management is needed to maintain continuous network compliance and validate that planned changes do not introduce any new risk. Secure change management incorporates risk assessment and standardized process to reconcile flagged changes, and troubleshoots where needed.
For example, a change management process can flag when a network change will expose vulnerabilities, when a firewall change opens access to risky services or when there is unauthorized access. More importantly to maintain network security change management process can be used to check the impact of a proposed change before implementing it.
