About CCNA Security Track:
Cisco Certified Network Associate Security (CCNA Security) validates associate-level knowledge and skills required to secure Cisco networks. With a CCNA Security certification, a network professional demonstrates the knowledge and skills required to develop a security infrastructure, recognize threats and vulnerabilities to networks, and mitigate security threats. The CCNA Security curriculum emphasizes core security technologies, the installation, troubleshooting and monitoring of network devices to maintain integrity, confidentiality and availability of data and devices, and competency in the technologies that Cisco uses in its security structure.
There is only one exam that needs to be completed to achieve this certification.
Any valid Cisco CCENT, CCNA Routing and Switching, or any CCIE certification can act as a prerequisite.
