More than half of IT leaders in the US government are more confident about their agencies' cybersecurity capabilities than they were two years ago, according to a survey released today.

Despite a handful of high-profile government breaches this year, 58 percent of those surveyed believe their agencies are more secure, while just 12 percent feel less secure, according to the survey by Cisco. The largest breach was the 3 May theft of a US Department of Veterans Affairs laptop and hard drive containing the personal information of 26.5 million military veterans. The hardware was recovered in late June.

However, the August phone survey of 200 US government IT decision-makers also found they are putting more time into cybersecurity. Sixty-three percent of respondents said they are spending more time on security issues than they were two years ago.

"More folks are working at security and information assurance, often not as full-time jobs but as part of their jobs," said Daniel Kent, director of systems engineering for Cisco's US federal sales organisation.

Funding concerns were identified by 67 percent of respondents as the top impediment to improving cybersecurity. Half of all respondents identified their existing security architectures and a lack of standards as major impediments, with just under half identifying a lack of management support and a lack of experienced staff as major barriers to improvement.

The problem with existing security architectures seems to be a lack of cohesiveness, Kent said. Agencies have been working on creating defence in depth by buying products that fix targeted security problems, but respondents don't see how these piecemeal systems fit together, he said.

Survey respondents represented more than 45 US agencies and included chief information officers, program managers, IT directors and managers and line-of-business managers. All respondents had some level of responsibility for decision-making for network security.

Asked which security components were most important, 92 percent of respondents identified network firewalls, and 92 percent identified server and workstation security. Eighty-nine percent identified network intrusion detection technology, while 78 percent named email and messaging security. Seventy-eight percent also identified incident response capability, while 74 percent picked security audits.

Asked what security concerns keep them up at night, 46 percent said reduced operations because of security breaches, and 40 percent said a loss of employee or customer privacy due to data breaches. Another 39 percent said security concerns associated with remote or mobile workers.

Forty-eight percent said they were confident that automated software tools will address their agencies' security issues in the future, while 17 percent said they were not confident. Automated tools will allow IT workers to "do more with less", Kent said.

Market Connections conducted the survey, a follow-up to a November 2005 survey on government cybersecurity commissioned by Cisco.
