Aggressive Network Self-Defense 128

Posted by timothy from the scenario-based dept.
nazarijo (Jose Nazario) writes "Continuing in the new theme of fiction and technical how-to, Aggressive Network Self-Defense brings together several authors to provide a wide range of material. Syngress' niche in this space seems to be breaking new ground -- and for the most part, it works. While you don't get as in-depth a treatment as a typical technical book gives you, there is an added dimension: namely, a more realistic scenario of how these tools fit together in a real, live series of actions." Read on for the rest of Nazario's review.

summary take your security into your own hands to identify, target, and nullify your adversaries

Not being a big fan of most fiction (I tend to prefer history), it's hard to say definitively good or bad things about the quality of the writing. What I can say is that it's infinitely less irritating, and far more realistic, than Neal Stephenson's Cryptonomicon or Gibson's Neuromancer. No over-the-top smearing of adjectives to describe the mundane, and no unrealistic sequences of events. Then again, there's no character development and no real story progression, so it's not great fiction.

As a series of hacker vignettes, the book works just fine, and very well for the purposes at hand. Basically, what the authors want you to get from the book is two-fold: First, they want you to debate the issues around "strike back" attack methodologies. Several of the authors are open advocates of what are legal grey areas and open moral questions in the field of network security. Secondly, they want you to see how it's done, what you do when you actually use a tool to achieve a goal. Most books that do this, like Hacking Exposed, cover far more tools, but they usually do so without showing you each tool's use in a real-world scenario.

I won't bore you with a lengthy, detailed overview of the first part of the book. Like I said, it's a series of part fiction, part tutorial series of short stories. In them, you'll see tools like Metasploit, virus creation, some nmap, sniffers, and keystroke loggers, all in action, being used as an operator would use them, and achieving real goals. This is more valuable than a basic manual, and the stories themselves act as a nice setting. While not great fiction writers, the authors are decent enough at the job, and they write the technical material clearly.

The second part of the book is interesting. It makes up about a fifth of the book in volume, but a lot more in technical weight. The book bills this section as "The technologies and concepts behind network strike-back," and that's an accurate summary. It's a series of four unique perspectives and technical chapters that complement the rest of the book quite well.

The first introduces ADAM, the "Active Defense Algorithm and Model," which develops a methodology for network administrators to actively defend their networks against attacks. It's quite interesting, and brings together a number of risk models in an uncommon take. The authors are academic researchers from the University of Idaho, so it's a lot more academic than the previous material in Aggressive Network Self-Defense, but it formalizes a lot of the thinking that was present in the writing of the stories and techniques.

The second is Tim Mullen's classic "Defending your right to defend." This is the original position paper shared by Mullen with the information security community in 2002 or so. Here, Mullen makes a compelling case for actually striking back at worm infected hosts. After all, the position holds, someone should do something about them to help clean up the Internet. While it's a position I disagreed with at the time and still do, Mullen's writing is articulate and an important read. It really helps you understand a lot of the thinking that went into the book itself.

Dan Kaminsky wrote the next chapter, "MD5 to be considered harmful someday." Largely considered to be a follow-on to Joux and Wang's one-way hash function research, what it shows is how practical such an attack can be. Kaminsky never fails to come up with interesting ideas he puts into practice, and he adds another level of depth to this book.

Finally, Aggressive Network Self-Defense ends with an interesting paper, "When the tables turn: Passive strike-back." Like any good paper, it has a clear and thoughtful motivation, and really demonstrates the principles at play, namely building network resources that don't simply lure the attacker in, they trip her up. There are so many ways to do this, the authors show us, and ultimately it's almost fun. A good way to end the book.

An over-arching concern with the book that I have is the question of ethics. Mullen, in the foreword, states that he hopes the book stirs a debate about the ethics of the actions in the book. However, the book itself falls short in this area. Instead, sometimes the characters get busted, and sometimes they don't, but just because they didn't get caught doesn't mean some ethical lines weren't crossed. All too often the authors leave the ethical debate up in the air. While I prefer this to overt preaching or questions, the style leaves me wondering if this goal was achieved.

So, where do I stand on Aggressive Network Self-Defense? In the end, I like it, more so than a book like Hacking Exposed or other "hacking how-to" types. The style of presentation doesn't lend itself all that well to exploring a very wide number of tools, but it does give you a deeper context to see how they assemble into something larger. For many people I expect it will be a page turner, and I think the format has some utility, as shown here.

      I use swatch to look for these SSH probes. Two rules seems to catch most of these: 1) looking for illegal users (such as test, which occurs most frequently) and 2) looking for root login password failures. If you need to allow root logins, I'd recommend requiring that auth be key-based with the poorly-worded without-password option for PermitRootLogin. Then, there would be no situation in which a legit SSH root login would trigger the rul

      This keeps the 5|<r1p7 |<1dd3z from being able to trivially find you SSH server.

      Ideally, you want to do this in combination with code that watches for a port-scan and adds a firewall rule to block the scanning address.

    In order (somewhat):

    2. NSLookup, Whois, etc. I even go so far as to use GeoIP to get city, state, ISP, etc. Get email addresses to send to.

    3. Look for open proxies on the address in the case of SPAM. If so, just drop the search there.

    4. Nessus check for potential vulns that might have been exploited by common/known worms. Essentially, find how they were exploited, and if there is no known reason, assume they are malicious.

    5. Take necessary actions to blacklist or block the IP on the offending protocol, or in some rare cases, kill the IP altogether. (rarer cases, the subnet)

    6. Google. You'd be amazed at what I can do here. I put in the direct IP, I put in email addresses I've collected to find out where the person posts, etc. I get to know the individual, who they are, and further deduce if they are malicious. I used to even go so far as to imiate someone of the opposite sex their age and talk to them on their favorite IM and ask them if they are a h4x0r and can help me "get back at my brother, the bully at school, the girl that stole my boyfriend" etc. (never assume the gender of a /. poster)

    7. Email at a minimum 5 people, including Incident Response (https://forms.us-cert.gov/report/), the offending ISP, any emails off of the website of the IP in question, etc. Half the emails I CC just so that the individuals take the email seriously. Occasionally these will contain logs, IM logs, who the person is, what they do in their spare time, what forums they visit, their picture (if any) and etc. I do this from a TOR-accessed Hushmail account, so no one knows who the hell it is. One time I sent the email to the offender's mother. He sure thanked me with some profanities on that one (which were subsequently forwarded to his mother).

    There's ways of "attacking back" in such a way that script kiddies die out, but you have to totally overwhelm them with your sheer capability to outsmart them.

    Let's face it, we're all guilty of being lax in our network activity and leave IP trails on logs that Google indexes. It makes no sense to sit back and complain about script kiddies when it's quite obvious that we're unwilling to take them to task when they probe. The information is there, you just gotta do some digging and learn how to use Google's Advanced features. It's important to make your response to their actions overwhelming, so they are never tempted to turn back to random probing again.

      No Action: A threat is detected, but no action is taken.

      Internal Notification: Using the organizational structure to notify the designated responder(s) of an active response situation.

      Internal Response: Applying active response actions within the domain over which the responder has authority (e.g. close a threat vector's associated port).
    • This brings us to an issue I've wondered about for a long, long time.

      Where are the detailed IP databases? Who is compiling them? (You know some intelligence and other agencies are surely generating these database, but are there any that are public other than the search engines?)

      Google would be great if you could put in an IP and get a list of all the things that IP searched on. Imagine the possibilities in tracking people down. Yes, a huge security issue, but you know it's being done. A few select co

    I wrote an article back in 2002 ( http://www.securityfocus.com/guest/16531 [securityfocus.com]), which was published on SecurityFocus, in response to Mullen's initial SecurityFocus article.

    Not having read the book, I can't be sure, but according to the review there didn't seem to be much of a dissenting opinion in the book on the question of whether aggressive tactics are desirable (or effective).

    That's unfortunate, since as you'll see in my article, I think a good argument can be made that aggressive network defense is both
    • You might wish to read item 4 in your own article again, especially "disabling your opponent's attack" - if it is possible to remove the "weapon" from the attacker's "hand" (read "malware" and "computer"), is it wise to then return it to them?
    • I would strongly disagree, read ADAM in the book for a legally and ethically thorough argument for active response. To generally disregard active response is a mistake and shows that the topic is miscategorized to only include strike-back and hack-back methodologies. An argument can be made that aggressive tactics are ethically and legally questionable in certain situations - but not in ALL scenarios (e.g. air traffic control threats, national security/life/safety critical systems). Active response has a
    • No, what's unfortunate is that you didn't bother reading my strikeback white-paper before writing your SF piece... Just like you didn't bother reading any of the book before posting this response. My strikeback concept and code for the associated neutralizing agents were *never* self propagating or worm-like, yet you go out of your way to make it seem like they were... Not only is guidance offered, but a framework proposed that specifically addresses the questions of when, where, and how to strikeback, ye
      • Having reread your BH presentation, and read the white paper (which I, frankly, somehow didn't find at the time) I have to say: you're right and I'm wrong! I do have a caveat, but first: some public self-flagellation.

        I honestly don't recall how I could have missed the final few slides of your presentation, where you indeed answer the questions that I posed in my SF article, i.e. you set limits on what should be done. I have to say that my paper was way too harsh considering that fact.

  • Can someone 'out there(As In - The US)' please get Syngress to "Force Replicate" this book to Local(As In - In~dia) Publishers cause i've read the sample chapter and boy, does it sound interesting... On a more serious note... Waiting for this book to hit the shelves in India (P.S. And if you're wondering, No, I'm not from Bangalore[If you know what I mean!])
    • I am the Publisher for Syngress. We are currently in negoatioations to have the book published in India. I will let you know as soon as soon as we have a deal in place and expected publication date.
      • Well, Thank you for that!!! I'm new to slashdot and the reason i posted here is because of the book review. I've read (and OWN!) both the 'Stealing the Network' books and have constantly visited my local bookstore to check for other Syngress titles, but mostly to no avail, and don't get me started on the local publishers website(BTW, I DID NOT say that!).
