As the Nexus platform has become a staple in the data center environment, securing the environment begins with the Nexus Operating System (NX-OS). The recently published NX-OS hardening guide seeks to deliver on that. The Cisco NX-OS Hardening Guide provides information to help administrators and engineers secure NX-OS system devices, inherently increasing the overall security of a network environment. With the ever-increasing opportunity for exploits and vulnerabilities to prevail, it is imperative that organizations adopt and apply best practices to harden their infrastructure devices. We all know that an environment is only as strong as the weakest link, thus every effort should be made to ensure that each device is hardened.
