AlgoSec recently published the results of a survey of 179 information security and network operations professionals conducted during the RSA Conference in February 2013, entitled "The State of Network Security 2013: Attitudes and Opinions" [PDF file] (h/t Softpedia).

According to the survey results, 64.5 percent of respondents said insiders present the greatest security risk. Just over 34 percent said external threats are their greatest concern.

Sixty-six percent of survey respondents said bring-your-own-device (BYOD) policies increase the risk of security breaches, and 40 percent said employee devices increase the risk of network and application outages.

More than 76 percent of respondents had suffered a network or application outage as a result of an out-of-process change, and 80.6 percent had suffered an outage, security breach or decreased network performance due to an application-related rule change.

Fifty-seven percent of respondents have adopted next-generation firewalls, and 56.5 of those who have said they did so in order to improve protection from attacks.

"Increasing complexity in network security not only impacts an organization’s ability to protect itself from cyber threats, but also hampers business agility," AlgoSec vice president of marketing and business development Nimmy Reichenberg said in a statement.

"Based on the survey results, it’s clear that organizations are faced with increasing insider threats as well as rising risk of network and application outages, but process improvement and better security policy enforcement that leverages automation can provide significant dividends," Reichenberg said.
