Network Security

A huge part of Information Technology (IT) relies on securing data from outside threats. You must harden a networks infrastructure against severe attacks; however, you need to find a balance between security and function. Fortifying your network is a high priority, but go overboard and you could prevent legitimate users from accessing network resources.

Threats come in all shapes and sizes. Not only do you need to protect users from outside dangers, but you must also protect them from each other. Employees bypass all external security once they walk through the front door; nevertheless, with proper practice and training anyone can secure a network against both internal and external threats.

Certification can help validate your knowledge in this important aspect of IT. Cisco offers several security related certifications. The Cisco Certified Network Associate (CCNA) Security credential emphasizes core security technologies. Once earned you can recognize and mitigate threats to a network, maintain device integrity, and protect data confidentiality.

Subsequently, you can earn the Cisco Certified Network Professional (CCNP) Security certification. This qualification requires a candidate to pass four exams. These exams focus on securing routers and switches, deploying Cisco firewalls, deploying Virtual Private Network (VPN) solutions, and implementing intrusion prevention systems.
