Network automation to enhance security
Security is enhanced by many orders of magnitude with SDN-based network automation. In addition to minimizing security breaches due to misconfigurations and inconsistent policies, SDN supports micro-segmentation policies, which offers a substantial improvement in security.
Micro-segmentation separates individual workloads into different zones or segments. These zones are secured individually and isolated from other segments. Using micro-segmentation, enterprise IT teams can implement virtual firewalls around servers to control the lateral movement of high traffic volume within data centers. In the case of a security breach, micro-segmentation limits the potential of lateral exploration of networks by hackers.
For agility, SDN functions are implemented in the hypervisor layer, wherein security policies are implemented in the workloads. When a workload moves, the security policies, and attributes move with it. This enables IT administrators to lock down the security postures, especially when the development community spins up new VMs.
The holistic visibility of the networks offers additional security as in addition to IT admins being able to monitor routing, switching, remote access, wired and wireless components, they can also monitor, detect, and prevent potential threats and attempted intrusions.

Concluding Remarks

The security, efficiency and visibility benefits of SDN-based network automation can propel organizations to increased profitability. To implement SDN as a well-defined service offering, it is also imperative to standardize the automation processes to ease adoption and lifecycle usage. Skills training and collaboration across functional teams are the crucial cultural components which enterprise leaders must address to exploit the benefits of SDN.
