Why learn Information Security - II?

Every day we hear about the newest attack, the latest exploit, or another cyber threat. In response, we hire security consultants, look for the best security team we can find, and buy the latest products from the security vendors. Information security isn’t limited to one sector, such as banks or finance, there are opportunities in retail, university settings and anywhere else, where data has value. The career prospects are bright for the candidates seeking a career in Information Security/Cyber Security. Information security is about defending data and critical information from unauthorized access, use, and potential destruction. It’s a field that is projected to grow by 22 percent through 2020 and opportunities are abundant for newcomers to this in-demand career. It should be noted that the demand for information security professionals has exceeded the demand for information technology professionals, and it is likely to continue as the times passes.
