Aussie NACs breached: survey

NACs should be custom built for success

One in five organizations have experienced a network attack, despite many having Network Access Controls (NACs) in place according to a survey.

The SecurityPoint 2008 IT Security Project Survey collected 150 responses from Australia and New Zealand across 10 industries including education, government and mining during December last year.

The report found more than 25 percent of breaches had affected organisations that are currently deploying NAC.

InTechnology network applications security engineer Kellie O'Brien said respondents ranked NAC as their fourth network security project, below 'secure remote access' and identity management.

"Australia is generally reactive rather than proactive when it comes down to installing NAC," O'Brien said.

"The definition of NAC is as varied as the reasons for implementing it and each [installation] is different because they are based on individual requirements.

"A crucial part of NAC is ensuring security policies are adhered to which can be difficult."

O'Brien said respondents in the education industry faced the majority of attacks despite being widely aware of data breach liabilities.

Encryption, data leakage, and securing portable devices and data backups were the top priorities for respondents.

Creating secure remote access to the corporate network rated second, followed by determining accurate methods of user authentication while maintaining simplistic network access.

NAC came in fourth, ahead of network traffic security involving the categorization and control of traffic and maintaining legacy systems.
