There’s no denying that security is paramount in today’s enterprise environment — but it can be tough to know what strategies you should implement to shore up the organization’s defenses. At the same time, companies are having to rethink their network management approach in order to keep up with the demands of their new, always-on business models.

The good news? Network transformation provides a unique opportunity to put security first. Network services offer a wide view of your network, so you can stay up to date on routing rules, access rules and VPNs. By designing a network map, you can then tie these rules to physical devices. And if you’re a security officer, having a micro-level view of the network can keep you informed as you implement specific rules, access policies and compliance guidelines.

Here are three strategies to consider when rethinking your network with security as the end goal.

1. Simulate Attacks

A network attack simulation can illustrate how existing security controls and business metrics will affect the enterprise during a crisis. Designing an effective simulation depends on your network’s ability to provide broad, reliable data. This information will help you identify any network security faults as they arise.

A secure network also needs a secure change management process that incorporates risk assessment in a standardized way. Change management procedures improve the stability and reliability of the processing environment by preventing unintended consequences and reducing risks posed by alterations. This process requires managers to outline the policies they want to govern the network.

2. Consider SDN

The network itself may need a makeover in order to get the most out of any advanced security tools you implement. Most newer solutions include automation — that means the network needs to respond appropriately. A software-defined network (SDN) will be better equipped to respond to changing security imperatives.

An SDN can respond in a rapid and meaningful way to security situations and provide a performance boost to specific segments as needed. This can make the network more secure, reducing stress on areas that were never meant to handle big traffic loads.

3. Redefine the Role of Network Manager

Network management techniques are based on an understanding of how all the elements of a network work together. Security experts make use of the same information from a different angle. As business needs evolve, you may find it’s time to rethink and redefine the role of network manager into a type of security professional. By integrating these dual skill sets, you can embed security into your network from the beginning.

If you want to rethink your security approach and bolster your organization’s defenses, transforming your network may just be the best place to start.
