network security jobs
Network security jobs refer to any activities designed to protect your network. Specifically, these activities protect the usability, reliability, integrity, and safety of your network and data. Effective network security targets a variety of threats and stops them from entering or spreading on your network.
The most common security threats include viruses, worms, and Trojan horses; spyware and adware; zero-day attacks (also called zero-hour attacks); hacker attacks; denial of service attacks; data interception and theft; identity theft.
Components of network security jobs
Examples of network security components are:
- Anti-virus and anti-spyware
- Firewall, to block unauthorized access to your network
- Intrusion prevention systems (IPS), to identify fast-spreading threats, such as zero-day or zero-hour attacks
- Virtual Private Networks (VPNs), to provide secure remote access
Cisco security certifications focus on the growing need for knowledgeable network professionals who can implement complete security solutions. The ASA Specialist certification identifies individuals who possess in-depth expertise with implementing security technologies using the Adaptive Security Appliance (ASA) technologies, especially firewall and VPN functionality.
