Network security professionals at Cisco have measured more than a quarter million unique instances of malicious code at work on the Internet at any given moment. Any of these malware routines could wreak havoc on systems, revealing company secrets or customer information, if left unchecked. In addition, a Lancaster University study found that physical threats to servers and client systems still pose major challenges for security professionals. Network security training ensures that IT workers understand how to prevent attacks and respond to breaches with the latest safeguards.

Network security courses can help current information technology workers build the skills necessary to land higher-paying jobs or earn promotions. Likewise, the right training program can help professionals from other fields segue into IT jobs within their current companies.
