A new Ponemon study reports that the number of data breaches caused by malicious attacksincreased from 31 percent in 2010 to 37 percent in 2011, with malicious insiders being responsible for 33 percent of attacks. In the report Ponemon states, “We think about the evil hacker, which is pretty serious stuff, but in our study, we find that it’s really the malicious insider – someone who’s nefarious or angry at the organization – that presents the real danger to the company.”
The study also reports that 39 percent of data breaches in 2011 were caused by negligent insiders. When you combine the threats posed by malicious and negligent employees, organizations of all sizes have cause for concern.
The good news is there are steps that can be taken to secure the perimeter within:
• Implement privileged identity management policies to create boundaries that enable end users and applications to communicate freely within an IT environment without worry of intentional, accidental or indirect misuse of privilege
• Implement a least privilege strategy, granting users only standard rights, but permitting elevation of privileges as required to enable them to do their jobs effectively
• Secure and monitor passwords for the ability to track and log their use, while having visibility into the granular details about when someone logged in, the keystrokes they performed and the information they accessed
With the right combination of policies and strategies in place, organizations can mitigate the opportunity for an employee – whether malicious or negligent – to take a risky action in the first place.
