Physical access to an organization's secure areas, equipment, or materials containing sensitive data may make it easier for a malicious insider to commit a crime. Therefore, an organization's physical security controls are often just as important as its technical security controls. This entry reviews some real case examples of physical security issues as well as some physical security controls.
Hello, this is George Silowash from the Insider Threat Center at CERT. I had the opportunity to attend RSA Conference 2011 with two of my colleagues, Dawn Cappelli and Joji Montelibano. Insider threat was a popular topic at the conference this year--vendors discussed it in sales pitches, and security practitioner presentations focused on the problem. In addition to being speakers at the conference, staff members from the Insider Threat Center were there to gather ideas of what is being done in industry to address insider threats. This entry describes some of the strategies that organizations are using.
Developers often have full access to the source code of critical systems to do their job. This same access can also be used to insert logic bombs, sabotage the system, or siphon money from an organization. We have seen numerous cases of developers and system administrators exploiting parts of the software development lifecycle to commit their crimes. In this entry, we examine some recent cases involving developers who became malicious insiders.
This is the second of two blog entries that explore questions we were asked during a recent meeting with leaders from the U.S. financial services sector. In this entry, we focus on what role malicious insiders typically hold in an organization: a non-technical position, a technical position, or both. "Non-technical" includes positions such as management, sales, and auditors. "Technical" includes positions such as system or database administrators, programmers, and helpdesk employees. "Both" includes overlapping jobs such as IT managers.
We recently met with leaders from the U.S. financial services sector, and they asked a number of questions about recent trends in insider threat activities. We are often asked these types of questions, and we can answer many of them right away. Others require more extensive data mining in our case database. In this entry, we address the following question:
Between current employees, former employees, and contractors,
is one group most likely to commit these crimes?
The answer to this question has some important implications, and not just for these particular meeting attendees. If, across all types of incidents and all sectors, the vast majority of incidents are caused by current, full-time employees, organizations may focus on that group to address the vulnerability. If, on the other hand, there are a large number of part-time contractors or former employees, there may be different controls that an organization should consider using.
Members of the Insider Threat Center will be giving numerous presentations during the next few months:
Hello, my name is Joji Montelibano, and I work in the CERT Insider Threat Center. When members of our team give presentations, conduct assessments, or teach courses, one of the most common questions is, "Just how bad is the insider threat?" According to the 2010 CyberSecurity Watch Survey, sponsored by CSO Magazine, the United States Secret Service (USSS), CERT, and Deloitte, the mean monetary value of losses due to cyber crime was $394,700 among the organizations that experienced a security event. Note that this figure accounts for all types of security incidents, including both insiders and outsiders. What is especially concerning is that 67% of respondents stated that insider breaches are more costly than outsider breaches.
Hi, this is Chris King. Any organization that stores data about individuals has a responsibility to protect that information. We regularly hear news stories about celebrities' personal information being stolen and released to the media. Some of these leaks are caused by unauthorized individuals at organizations who are entrusted with confidential data. Recently, the media reported on an incident in which the confidential records of a contestant on a popular reality television show were improperly accessed by employees in multiple law enforcement agencies, a municipal court, a prosecutor's office, and the state department of motor vehicles. These people were eventually identified and punished, but this incident should remind organizations that deal with confidential information that it is important to be proactive about monitoring for unauthorized access.
