Large organizations, today, are rapidly transforming their legacy IT infrastructure by incorporating technologies like cloud computing, big data analytics, and the internet of things (IoT). With an increase in network usage, the challenges in securing connections have also seen a significant increase. Technology silos, an abundance of manual processes, and a shortage of skilled network security personnel make it difficult to prevent, detect, or remediate security breaches. Consequently, the need for efficient network security architecture has risen. The following are ways to calibrate the network security architecture for enhanced efficiency,
The emergence of software-defined network (SDN) has given organizations the ability to effectively manage and maintain access control. Organizations have set workable access control policies that determine who can gain access to critical data. However, without flexibility in the policies, the pace of automation, workforce comfort, minimization of downtime, and the enhancement in the security of a network could see a significant reduction.

Application of Security Controls
After the implementation of flexible access control, organizations still need to ensure that authorized sessions do not let malicious data enter the network. This is where the importance of the previously mentioned policy-based network security returns to focus. The network security platform needs to be selective and flexible before applying control to every session. Aspects such as the source, destination, time, and geography of the connection should be taken into consideration to effectively protect the network.
Strategies for Protection
A policy-based security approach will enable organizations to inspect data traffic and ascertain which security controls are applicable based on the specific connection. For incoming connection requests, a policy that routes data through an email security gateway or a malware scanner should be set up. Likewise, for outgoing traffic, encrypted data should be decrypted, before sending it through a web filter to detect if there is a misuse of data or if it is connecting to a malicious site.
Optimization of Network Capacity
Capacity plays an important role in network security; however, organizations do not always have the luxury of upgrading network security in tandem with the network bandwidth. The implementation of a network security platform that notifies organizations when a specific security control is at capacity can ensure efficient management of network security.
To summarize, the possibilities of switching to a network security platform that incorporates all the aforementioned improvements are endless. However, scaling of networks and security controls cannot occur concurrently without the complete overhaul of network architecture, and thus, organizations need to apply intelligence to determine how security controls are implemented.
