Insider Threat
Ben Rothke writes "Thousands of computer security books have been published that deal with every conceivable security issue and technology. But Insider Threat is one of the first to deal with one of the most significant threats to an organizations, namely that of the trusted insider. The problem is that within information technology, many users have far too much access and trust than they should truly have." Read the rest of Ben's review.

summary
Excellent overview of the insider threat to networks and information systems
The retail and gambling sectors have long understood the danger of the insider threat and have built their security frameworks to protect against both the insider and the outsider. Shoplifters are a huge bane to the retail industry, exceeded only by thefts from internal employees behind the registers. The cameras and guards in casinos are looking at both those in front of and behind the gambling tables. Casinos understand quite well that when an employee is spending 40 hours a week at their location dealing with hundreds of thousands of dollars; over time, they will learn where the vulnerabilities and weaknesses are. For a minority of these insiders, they will commit fraud, which is invariably much worse than any activity an outsider could alone carry out.
Insider Threat is mainly a book of real-life events that detail how the insider threat is a problem that affects every organization in every industry. In story after story, the book details how trusted employees will find weaknesses in systems in order to carry out financial or political attacks against their employers. It is the responsibility to the organization to ensure that their infrastructure is designed to detect these insiders and their systems resilient enough to defend against them. This is clearly not a trivial task.
The authors note that the crux of the problem is that many organizations tend to think that once they hire an employee or contractor, that the person is now part of a trusted group of dedicated and loyal employees. Given that many organizations don't perform background checks on their prospective employees, they are placing a significant level of trust in people they barely know. While the vast majority of employees can be trusted and are honest, the danger of the insider threat is that it is the proverbial bad apple that can take down the entire tree. The book details numerous stories of how a single bad employee has caused a company to go out of business.
Part of the problem with the insider threat is that since companies are oblivious to it, they do not have a framework in place to determine when it is happening, and to deal with it when it occurs. With that, when the insider attack does occur, which it invariably will, companies have to scramble to recover. Many times, they are simply unable to recover, as the book details in the cases of Omega Engineering and Barings Bank.
The premise of Insider Threat is that companies that don't have a proactive plan to deal with insider threats will ultimately be a victim of insider threats. The 10 chapters in the book expand on this and provide analysis to each scenario described.
Chapter 1 defines what exactly insider threats are and provides a number of ways to prevent insider threats. The authors note that there is no silver bullet solution or single thing that can be done to prevent and insider threat. The only way to do this is via a comprehensive program that must be developed within the framework of the information security group. Fortunately, all of these things are part of a basic information security program including fundamental topics like security awareness, separation and rotation of duties, least privilege to systems, logging and auditing, and more.
The irony of all of the solutions suggested in chapter one is that not a single one of them is rocket science. All of them are security 101 and don't require any sort of expensive software or hardware. Part of this bitter irony is that companies are oblivious to these insider threats and will spend huge amounts of money to protect against the proverbial evil hacker, being oblivious to the nefarious accounts receivable clerk in the back office that is draining the coffers.
One example the book provides is that many companies feel they are safe because they encrypt data. An excellent idea detailed in chapter two is to set up a sniffer and examine the traffic on the internal network to ensure that the data is indeed encrypted. The reliance on encryption will not work if it is not setup or configured correctly. The only way to know with certainty is to test it and see how it is transmitted over the wire. Many companies will be surprised that data that should be unreadable is being transmitted in the clear.
Some of the suggestions that authors propose will likely ruffle some feathers. Ideas such as restricting Internet, email, IM and web access to a limited number of users may sound absurd to some. But unless there is a compelling business need for a user to have these technologies, they should be prohibited. Not only will the insider threat threshold be lowered, productivity will likely increase also.
The author's also suggest prohibiting iPods or similar devices in a corporate environment. The same device that can store gigabytes of music can also be used to illicitly transfer gigabytes of corporate data.
Insider Threat provides verifiable stories from every industry and sector, be it commercial or government. The challenge of dealing with the insider threat is that it requires most organizations to completely rethink the way they relate to security. It is a challenge that many organizations would prefer to remain obvious to, given the uncomfortable nature of the insider threat. But given that the threats are only getting worse, ignoring them is inviting peril.
The only lacking of the book is that even though it provides a number of countermeasures and suggestions, they are someone scattered and written in an unstructured way. It is hoped that the authors will write a follow-up book that details a thorough methodology and framework for dealing with the insider threat.
Overall, Insider Threat is an important work that should be required reading for every information security professional and technology manager. The issue of the insider threat is real and only getter worse. Those that choose to ignore it are only inviting disaster. Those companies that will put office supplies and coffee under double-lock and key, while doing nothing to contain the insider threat are simply misguided and putting their organization at risk.
Insider Threat is a wake-up call that should revive anyone who doubts the insider threat.

I've experienced working at a place where an employee walked out with information (and was subsequently sued into oblivion). Afterwards, all computers were locked down to the point where it made it nearly impossible to get any work done. Ever try to troubleshoot a data issue when you have to get your supervisor to log you into the database server every time? It can be hard to find a happy medium.
There can often be a trickle down effect of that as well... resulting in nearly the entire company having too much access.
The company I work for for instance... EVERYONE has administrator rights to their desktop. Everyone from us lowly engineers in the back who bend our machines to their limits... up to the sales people who just use our proprietary apps (which do not require admin access) and Outlook.
Long ago, IT tried to restrict most users... unfortunately enough complained about not being able to do what they wanted (not always what they needed to do), and the policy was reversed.
This has of course enabled HR persons to install spyware that was suggested by a secretary.
I am still waiting for the day we have someone run a piece of malware who didn't know any better that brings the entire network, and most of it's users to their knees.

The main issue is that most people can look at any patient. This is considered a "necessary evil" as sometimes unexpected clinicians might be looking at a patient's information and we don't want to block access in a life threatening situation. Instead, we review access after the fact, in addition to putting certain blocks in place:
- Unusual access is audited. This includes people looking at patients who happen to be employees, specific audits of local celebrities, and so on.
- Random audits. Periodically, someone will check to see what a random person is doing.
- Probation. New users are audited at certain points, to make sure they're not abusing their new power.
- Hiding patients Certain patients are hidden from most users - this might include celebrities, legal issues, or patients who have requested it.
I see trust as a necessary part of functioning within an organization, though trust must be tempered with watchfulness. I'm a big fan of letting people do what they want, and then "break their kneecaps" if they abuse that trust. In real terms, this means prosecution and the like. Of course, I don't decide such things - that gets passed on to our legal department and I try not to follow up after that.This book reminded me of another good read, "Art of Deception" by Kevin D. Mitnick. You would be surprised how easy it is to get information from people.
I was working for a large retailer about five years ago when I accidentally sent the wrong pricing file for a sign-making program to all 105 stores in our marketing area. So I needed to get into each store's computer via PC Anywhere and manually change the file. It went something like this:
Mgr or Asst. Mgr.: This is Mr./Mrs./Ms. Manager, how can I help you?
Me: Hi, I know that you don't know me but this is Joe from Advertising. I make up the signs and there's an error with next week's file that I need to fix.
Mgr or Asst. Mgr.: Oh, well we certainly don't need wrong information on our signs. What do you need me to do?
Me: Right click on Network Neighborhood, double-click the connection and read me your IP address.
Mgr or Asst. Mgr.: Okay, it's xxx.xxx.x.xxx
Me: Super. I will be in your computer changing some stuff for a few minutes so don't be alarmed if stuff starts happening on your screen.
Mgr or Asst. Mgr.: Okay, thanks.
The crazy thing about it is *not one person* in the 105 stores ever questioned whether I should have that information even though none of them knew me or could ascertain where I was calling from. Not even close--they all cheerfully did what I asked without hesitation. Scary!!
