Forensic Discovery 123

Posted by timothy from the big-fat-y-incision dept.
Ben Rothke writes "When most people think of forensics, television shows like Quincy and CSI come to mind. Where such shows deviate from reality is the unrealistic speed at which the actors are able to identify, apprehend and prosecute the perpetrators. In the real world, (unlike television, where the crime must be solved by the end of the family hour), crimes are solved with slow, deliberate and methodical steps. The prodigious incidence of digital crime has elevated computer forensics to a critical role within the field of information security. The focus of computer forensics is twofold: first is the attempt to determine whether a breach has occurred and to stop the perpetrator; second is prosecution of the offender, if the breach was a criminal activity."

summary Forensic Discovery overview

Security luminaries Dan Farmer and Wietse Venema wrote one of the first vulnerability scanners (SATAN) almost 10 years ago; SATAN was the precursor to ISS Scanner, Retina and nmap. Venema wrote such well-known security applications as the TCP Wrapper program and the Postfix mail server. Farmer and Venema's new book Forensic Discovery is a valuable book that grounds a computer-savvy reader in the world of digital forensics.

An image of a pipe by artist René Magritte is on the cover with the caption Ceci nest pas une pipe. ("This is not a Pipe.") The picture demonstrates that an object exists on many planes; the simple recognition of the picture initiates the belief that we are seeing something, but it is only known in representation. Surrealist painting and digital forensics coalesce in that the digital forensic investigator must think broadly and unconventionally in order to reconstruct an incident, all the time keeping in mind that often what initially seems obvious is neither real nor correct.

The material in the book is an outgrowth of a one-time seminar the authors gave in 1999 on digital forensics and analysis. At the seminar, Farmer and Venema rolled out The Coroner's Toolkit (TCT), a collection of tools for gathering and analyzing forensic data on a Unix system. TCT is heavily referenced throughout the book.

The book initially seems thin, at just 198 pages, but there is no filler and the information is presented in a fast and furious manner. Part one of the book comprises 35 pages and is an introduction to the foundations of digital forensics and what to look for in an digital investigation.

Part two (chapters 3-6) is the nucleus of the book, which quickly gets into low-level details about file systems and operating system environments. While other forensics books focus exclusively on the discovery and gathering of data; Forensic Discovery adds needed insight on how to judge the trustworthiness of the observation and the data itself. Again, the idea is that not everything is as obvious as it may initially seem. An effective investigation often requires intense analysis, where meaningful conclusions take time.

Chapter 4, "File System Analysis," notes that while computers have significantly evolved since their inception, little has changed in last 30 years in the way that file systems actually handle data.

Chapter 5, "Systems and Subversion," is particularly interesting as it deals with system startup and shutdown, from a forensics perspective. The chapter shows that there are thousands of possible opportunities to subvert the integrity of a system without directly changing a file during startup and shutdown. A crucial decision that must be made during an incident is whether to shut down the system or let it remain on-line. There are advantages and disadvantages to each approach, and the book details them.

Part three (chapters 7-8) is about the persistence of deleted file information. The authors' research reveals that data can be quite resistant to destruction. The book shows that a huge amount of data and metadata can survive intended deletion as well as accidental damage.

Forensic Discovery is unusual in that other books on forensics are often nothing more than checklists and step-by-step instructions on what to do during an incident. Forensic Discovery provides a broad framework on the nature of data and how it can be recovered for forensic purposes. By understanding the underlying operating system, the act of analyzing and dealing with a security breach becomes much easier.

The book's target reader is anyone who wants to deepen his understanding of how computer systems work, as well as anyone who is likely to become involved with the technical aspects of computer intrusion or system analysis. The topics are too advanced, to make it the right book for the novice system administrator. For the technical reader, though, Forensic Discovery is one of the best computer security books published in the last year. The value of the information is immense, and the extensive experience that the authors bring is unmatched.

        Well, it was that "some" in "some consoling" that I wasn't sure about. How much? She's telling me on the first date that she's under tremendous stress. I appreciate her honesty and respect her for that but I suspect that if she feels the need to divulge that on a first date, the level of consoling is likely to be more than "some". That's what I was worried about. To be dating a girl with a face and a body like that who knows her way around computers like a pro and who is doing a job that is clearly a service to mankind sounds like a geek's wildest dreams come true. But therein lies the problem: this is the kind of girl who most of us would fall head-over-heels for. I was afraid of getting really wrapped up in her and then having to endure of heartache of having her crying in my arms once a week or more. Or having her push me away in bed because she had seen something at work that had turned her off of sex for the next two weeks. You can call me an ass or a dumbshit but seriously think about it for a moment. This was going to be a major emotional roller-coaster for me.

        I'm reminded of some poor sap here on slashdot who was telling us what it's really like to have a nympho girlfriend. It sounds great until you are presented with the reality of the situation, namely, that she absolutely needed sex every time he put his arm around her. Look, I still think that woman I dated was very desirable on many, many levels but I also think I did the right thing by stopping that relationship before I got sucked into her work as well.

      The Dutch police has a huge database of all kinds of (child pornography) pictures. Of each picture they have a hash. When they confiscate the pc of somebody who is suspected of having child pornography, the first thing they do is run the hashes against the pictures on the system. This saves them from having to look at all those pictures, they can now focus on the unknown ones. Great thing is also that the hashes are admissable in Court as evidence.

      • Depending on the hash method, can't different strings/files sometimes result in the same hash?

        I'd assume that if you nailed somebody with 10+ hashes you've got them, but 1-2 matches might be false positives?

        Also on the hash front, wouldn't any simple alterations to the file (format conversion, brightness/contrast adjust, resize, etc) break the hash? Perhaps even an "echo 1 >> somefile" would kill it?

        Useful, certainly, but likely with some flaws/pitfalls.

      The mere presence of encrypted data is usually a tip-off to a decent examiner that something interesting is in there. There are even programs and statistical methods for finding different types of encrypted data on a drive. And there are all sorts of ways to recover passphrases...if you have enough evidence to get the suspect to talk, they'll usually give it up. Not every forensic technique is a technical one...

      Most of all, there is a lot of data that can't be encrypted to cover one's tracks, especially in the corporate environment where firewalls and other security systems log activity.

      With a decent encryption method, you can almost guarantee that the data is secure. The better the encryption is, the larger the server farm/super computer they need to crack it. Although, it can be seen as contempt of court if you are required by law to give them the keys used to encrypt it and you fail to do so. Just because the data is unreadable by them doesnt mean they cant put you in the slammer.

    The primary purpose of forensic science is to pretend to be a real science so as to fool people into thinking that there are reliable ways of tracking down who you are if you commit a crime. It's the myth of forensic science that keeps the crime rate down, not actual forensic science successes. Ask N forensic scientists when someone died, how long it was since their last meal and so on and you'll get N differet answers. But programs like CSI help to mislead people into thinking this stuff actually works.

    In the days of yore the torture was used much leass than people imagine. Just the threat of torture was enough to make people confess. The same goes with forensic science. A cop says: "we have your DNA and we know it's you for sure" and that's enough to make someone confess. And as long as programs like CSI keep airing people will continue to fall for it.

    It's like asking for "total realism" in science fiction... you are aware that faster than light travel is, at best, totally unproven and most likely completely impossible? (Save the discussion on the possibility of FTL for sci.physics, please, this is just an example.)

    So many fan-boy types ask for things that if they got them, they'd hate even more. I for one am glad the characters aren't making constant references to the amount of time something is taken, and I for one am glad that when they dig through an entire day of garbage in Los Vegas, they show about ten seconds of walking around, followed by the necessary discoveries. Are you seriously asking them to show the five or six hours it might have taken in real life? You feel free to watch it, I can guarantee I wouldn't.
    • here might be the issue some have: how many people actually fly around in a starship boldly going where blah blah blah compared to the perception tv viewers have of crime scene investigators that do work similar enough to that they see on their show?

      it is easier to disbelieve startrek but harder to disbelieve CSI. you commit a crime you imagine that some team will investigate it like in the show (how ever long it takes). but you flip open your communicator dial 911 and ask them to beam you up, and you migh

    You're telling me that it takes longer than an hour to solve a crime? I've been to football games -- I know that what's on the TV is what's actually happening in real time. If it's on the TV, it must be real.

    Besides, who wants to watch a show where they uncover one clue a week, or get a subpoena, or nothing happens that week? Surprisingly, people don't want to watch real life when they turn on the TV (and don't even try to say that reality TV has anything to do with real life).
    • I just watched a guy make a sandwich and then go to bed on Big Brother, I agree...

      They're still showing everyone asleep! this goes on for an hour!? nothings happening!

      TV is for cutting out the boring bits.
    • on the contrary. if people could "tivo" real life we would all become peeping toms. think about a parent being able to watch their child's life in a time-shifted manner at any point of their day. maybe some warez will be released that can boil down a person's day or week or month or year etc into an hour long show. and the best part is that this isnt even reality tv. maybe you can come up with a name for that kind of tv.

    I've got lovely news for you: Unless you are able to watch a computer from the time it is put on the network to the time that removed for evidence collection, you can say *VERY*LITTLE* about what someone may or may not have done with that computer.

    Here's a little story from several years back. A friend of mine who was doing deployed support for one of the armed services used an account at a major American university, which he was authorized to used, to download/store updated cisco images due to limited b
    • Right... This guy had a decently bad experience. Everyone makes mistakes. Obviously this case had a fair bit of incompetence, but I doubt this is the standard. Also, keep in mind that 90% of what is termed "Computer Forensics" has nothing to do at all with network activity. Computer Forensics deals mostly AFAIK with such things as: 1. A suspected pedophile is arrested, and they pull his computer. They find stuff like kiddie porn, and MSN logs where he tries to get little ones to meet him in the park e

        Currently there is a heavy emphasis on making a lot of assumptions about what has happened based upon what is on someone's computer due to the "infallibility" of checksumming disk contents and the software that makes the process palatable to courts and legal profession. That makes it possible for me to get you in a lot of trouble quite easily. I seriously doubt that most folks know everything actually stored on their hard drives or how it got there. The list of malware is so very long that it is impossib
