Professionals who have the skills required to secure Cisco networks often seek a CCNA Security (Cisco Certified Network Associate - Security) certification. A CCNA Security certification acknowledges a professional's skill in developing a security infrastructure, mitigating security threats, and recognizing all types of threats and vulnerabilities to the network.
Candidates who wish to gain the CCNA Security (Cisco Certified Network Associate - Security) certification must have specific knowledge in core security technologies, including the skills needed to install, troubleshoot, and monitor network devices. A CCNA Security certification validates a professional's ability to maintain the integrity, confidentiality, and availability of devices and data. The certification also acknowledges a professional's competency in Cisco technologies used in security structures.
Prior to attempting to pass the CCNA Security (Cisco Certified Network Associate - Security) certification exam, candidates must already possess a current CCNA or CCIE certification. Once that prerequisite has been met, candidates must pass the 640-554 Implementing Cisco IOS Network Security exam. Training for the 90 minute exam is recommended, but not required.
The CCNA Security certification lasts for three years. Renewal consists of passing any of the following exams: a CCNA Concentration, any professional level exam, CCDA DESGN, Cisco Specialist, CCIE Written, CCDE Written, or CCDE Practical. Additionally, candidates may renew their CCNA Security certification by passing the Cisco Certified Architect interview and board review to extend lower certifications.
