Networking Security Career Overview
While individual computers are powerful tools, their full potential isn’t realized until they’ve been hooked up to one another in networks or connected to the largest network of all, the Internet, where they can communicate with millions of others. Network analysts and administrators ensure that computer networks serve the needs of customers and fellow employees, while computer security workers keep networks safe from unauthorized intrusion.
Networking and computer security are growing fields with many opportunities for individuals who possess the technical know-how and training. Entry-level network and computer security administrators are involved in day-to day operations, responsible for:
- installing
- maintaining
- updating network hardware and software
With experience, administrators can advance to positions where they are responsible for developing and designing how networks and network security systems operate.
People who work with network and computer security must have strong technical knowledge as well as analytical and troubleshooting skills. Because the nature of the work requires interaction with computer users and other technicians, network administrators and computer support specialists should be able to communicate effectively what is often dry technical information.
Networking Security Training & Education
