Networking expertise remains critical within IT departments. Firms depend on their internal systems to share data companywide and power their business-critical applications. In particular, demand is strong for professionals experienced in identifying and preventing security breaches. Recent investment in wireless and mobile technologies is creating a need for experts skilled in supporting systems that allow companies to share data with individuals outside of their internal networks.
Typical responsibilities for networking professionals include:
Helping firms administer, define, maintain and expand local area networks (LANs), wide area networks (WANs) and wireless local area networks(WLANs), including voice and data integration
Incorporating distributed data, troubleshooting technical problems
Developing, implementing and maintaining integrated programs to protect the confidentiality of an organization's information resources
