The Security Certified Network Specialist (SC0-451) certification is designed to examine the knowledge of networking and security skills required by a network security professional. This validation is done basically on the following technologies: Network Defense Fundamentals, Advanced TCP/IP, Routers and Access Control Lists, Designing Firewalls, Configuring Firewalls, Configuring Virtual Private Networks, Designing an Intrusion Detection System, Configuring an Intrusion Detection System and Securing Wireless Networks.
There are no specific prerequisites for this certification but any kind of Security+ certification or its equivalent work experience is recommended.
It provides a track for the following certifications:
- Security Certified Network Professional (SCNP)
- Security Certified Network Architect (SCNA)
- Certified Information Systems Security Professional (CISSP)
- Certified Information Security Manager(CISM)
- Certified Wireless Security Professional(CWSP)

You will be required to attempt 60 questions in 90 minutes. You need to score 75% to pass the exam.
Having such certification shows the eligibility graph of a candidate in today’s IT industry. People with security certifications receive consistently more appointments from today’s industries and get higher base salary, bonuses, and raises as compared with other, less specialized IT positions
