New Delhi: Even as 2013 was marked by an unprecedented growth in malicious traffic, firms globally are grappling with a shortage of over a million cyber security professionals as they try to monitor and secure networks, a study by Cisco said.

According to the networking solutions major, overall vulnerability and threat levels reached their highest in 2013, ever since it began tracking in May 2000.

Its 2014 Annual Security Report (ASR) reveals that 2013 was a "particularly bad year", with cumulative annual threat alert levels increasing by 14percent since 2012.

Organisations in India are also witnessing a huge growth in cyber attacks and intrusions and the country faces shortage of about 4 lakh trained cyber security professionals.

"In 2013 there was an unprecedented growth of advanced attacks and malicious traffic that unfortunately reached historic levels," Cisco Leader Security Business (India and SAARC) Diwakar Dayal told PTI.
