Run Apps on Cisco ISR Routers

Earlier this month we joked that the Sguil project was acquired by Cisco, such that Sguil would be integrated into Cisco platforms. Cisco routers already run Tcl, but now thanks to Cisco's new Application eXtension Platform, other possibilities are developing. According to Optimize Branch Footprint with Application Integration, Cisco says:

  • Linux-based integration environment with downloadable Software Development Kit (SDK)

  • Multiple applications support with the ability to segment and guarantee CPU, memory, and disk resources

  • Certified libraries to implement C, Python, Perl, and Java applications

  • Supported by Cisco 1841, 2800, and 3800 Series Integrated Services Route


Sun used to say The Network is the Computer. Cisco now states The Network as a Platform. In other words, why deploy another server or appliance if you can just run it on your Cisco router?

I am unsure how this will play out. I figure Cisco just wanted to add to the confusion caused by virtualization with their own take on consolidating platforms. At some point I see one giant box (labelled Skynet probably) with a massive antenna to which we all connect our dumb terminals via wireless.

I'd like to get a Cisco 2800 series ISR router to try this out... donations are welcome. :)

I am curious to what level they will allow you to run and access the hardware. There are times where a 2811 will not run the routing protocols I need. I would love to throw quagga on the aXp board and deal with those shortcomings.

As security profesionals devices like these pose a pardigm shift. We think of full OS to be Linux, *BSD, MacOS, or Windows. Most technical implementation guides are written that these assets must posses AV and other NIST 800-53-ish controls. With the platform being so specialiazed yet so open, how do you deal with the implications?

With all of this extra code and complexity more vulnerabilities are sure to arise. I do not like my routers and switches being webservers, proxies or anything but what they are, simple and single purposed (possibly dual)is the approach that I find works best for me. We have deployed 100's of 2811's and I’m not yet convinced that you can turn up more than a few features simultaneously without 1) running out of system resources or 2) having to complex a config to manage on a large scale

Cisco is trying to compete with Crossbeam by providing the "platform." As a security guy this stuff just looks like another box to secure, but instead of a single purpose box that can be checked via config and input / ouput monitoring we now have all the 'features' of a general purpose machine. Simple comparison - whats the difference between your audit checks for a router and a windows / linux host? I bet it's pages in lenght and hours in manpower.

seperation of duties? Ask Cisco and wave your hand in front of their eyes when you get the dear in the headlights response.

One of the technical guys I respect the most likes to quote "Let routers route, firewalls firewall, and hosts host."

Wow, really surprised by the comments so far on this topic, reminds me of comments made when VMware was new to the world---too complex, extra layer of troubleshooting, unsecure. You can fight against the wind, or go with the flow…
Having deployed over 6000 2800 series routers running CME (Voip) and Firewall IOS I seen no problem mixing services, if configured correctly.
As for the single function devices, that fight was lost many years ago, security features, VoIP, the merging of IPS and firewall, WLAN on switches, etc... it’s a natural evolution that shortens the ROI.
Learn or die gentleman---then again the world always middle-level techs, or you can find a small shop.

I thought this post was interesting, especially in light of Felix Lindner's talk at Blackhat in DC about Cisco IOS forensics.

Do you think these kinds of developments will ultimately make the routing infrastructure a more attractive target for exploits or do you think this is no big deal?

Zeek in Action Videos

Image
This is a quick note to point blog readers to my Zeek in Action YouTube video series for the Zeek network security monitoring project .  Each video addresses a topic that I think might be of interest to people trying to understand their network using Zeek and adjacent tools and approaches, like Suricata, Wireshark, and so on.  I am especially pleased with Video 6 on monitoring wireless networks . It took me several weeks to research material for this video. I had to buy new hardware and experiment with a Linux distro that I had not used before -- Parrot .  Please like and subscribe, and let me know if there is a topic you think might make a good video.

MITRE ATT&CK Tactics Are Not Tactics

Just what are "tactics"? Introduction MITRE ATT&CK  is a great resource, but something about it has bothered me since I first heard about it several years ago. It's a minor point, but I wanted to document it in case it confuses anyone else. The MITRE ATT&CK Design and Philosophy document from March 2020 says the following: At a high-level, ATT&CK is a behavioral model that consists of the following core components: • Tactics, denoting short-term, tactical adversary goals during an attack; • Techniques, describing the means by which adversaries achieve tactical goals; • Sub-techniques, describing more specific means by which adversaries achieve tactical goals at a lower level than techniques; and • Documented adversary usage of techniques, their procedures, and other metadata. My concern is with MITRE's definition of "tactics" as "short-term, tactical adversary goals during an attack," which is oddly recursive. The key word in the tacti

  I've completed the TaoSecurity Blog book series . The new book is  The Best of TaoSecurity Blog, Volume 4: Beyond the Blog with Articles, Testimony, and Scholarship .  It's available now for Kindle , and I'm working on the print edition.  I'm running a 50% off promo on Volumes 1-3 on Kindle through midnight 20 April. Take advantage before the prices go back up. I described the new title thus: Go beyond TaoSecurity Blog with this new volume from author Richard Bejtlich. In the first three volumes of the series, Mr. Bejtlich selected and republished the very best entries from 18 years of writing and over 18 million blog views, along with commentaries and additional material.  In this title, Mr. Bejtlich collects material that has not been published elsewhere, including articles that are no longer available or are stored in assorted digital or physical archives. Volume 4 offers early white papers that Mr. Bejtlich wrote as a network defender, either for technical or pol
