Missing Open Source Security Tools?

Kinetic writes "There are many great open source security tools out there, Nmap, Nessus, and DSniff, just to name a few. However, with the world of security constantly changing, this begs the question, what open source security tools are missing? What commercial security tools have no viable open source alternatives?

      You think this is funny. Let me tell you a little story.

      I just took this past spring a course in "Network Security". The teacher got hold of a DARPA video on computer security and played it for us at one class session.

      You wouldn't believe this crap. The scenario was a country suspiciously similar to Iraq who set up a computer center with a bunch of Arab terrorist hackers and tried to drop America's infrastructure.

      So, of course, the brilliant and utterly boring (all these people looked like crew-cutted Republicans, it was unbelievable) used all sort of "cutting-edge technology" (that doesn't exist and won't for another two or three decades) to defeat the evil Arabs. It ended with them tracking the evil Arabs to their lair and a bunch of Special Forces guys busting in and shooting up the place (DIE, EVIL HACKERS! DIE!).

      The tech they showed involved a lot of voice-command and voice-response computer systems, all sorts of fancy graphics stuff, and of course something very much like Total Information Awareness that allowed them to know who everybody was no matter who the hell they were. They also had the ability to search out the source of any virus or hacker penetration in minutes and then commandeer the entire US infrastructure to repel the attack.

      Utter bullshit - and I told the teacher so at the end of the video.

      This was a DARPA "wish-list" video with absolutely no relevance to current computer security technology.

      At the end of the semester, I demo'd the Knoppix STD (Security Tools Distribution) to the class. One student asked if this stuff was "all command line". I said, well, it's all servers, and the servers all run UNIX, and servers usually are administered from the command line, so, yes, most of the tools (except for stuff like Ethereal and Nessus) was command line.

      Outside the jail, Apache 2 and mod_jk2 forward requests to the Apache Tomcat container instance running inside the jail on a unique port. Web applications running under Tomcat connect to the user's unique database port. This means that each user can stop and restart Tomcat, or destroy their Postgres database without affecting any other user.

      I've even given each jail it's own mini-init system, which executes start/stop/restart commands in an /etc/init.d directory.

Does a doctor really need to know Organic Chemistry? What would they possible actually use it for?"

      The Chemistry professor responded, "Well, a biochemist would obviously need and use Organic Chemistry, but if you just mean a practicing medical doctor, no, they don't need it and will never use it."

      "Well," asked the net tech, " why do you make them learn it then?"

      "We don't make them learn it to learn Organic Chem." replied the professor. " We make them learn it to learn deductive reasoning in a domain of applied set theory. It's to teach them diagnosis."

      And network security is a diagnostic field requiring deductive reasoning in a domain of applied set theory.

      Maybe we should make CS majors take Organic Chemistry.

      Or maybe we should just make them take math with a certain focus on logic and set theory and apply same against the computer (a mathmatical logic machine) network. Then maybe they could use general purpose logical tools to construct their own specific case tools, instead of being restricted to the domain of premade tools that often don't even fit their network situation (since every large network is unique in its structure and logic, and thus no outsider can know the sets, or the possible set of logical prepositions).

Something that implempents the more advanced features of Sniffer Pro or whatever they are calling it this week. Better searches, better ability to highlight and get data. Also the enahancement I would really like to see in tcpdump (and thus all the frontends for it) would be the ability to filter on x.x.x.x x.x.x.x in other words to be able to see traffic from or too a specific IP and another IP. This comes up in testing for me all the time. For example I want to see if a given packet is making it from my PC to a device somewhere. If that device happens to be chatty it would be nice to be able to filter it down to between it and my PC. Since I'm normally admining at least one of the devices between me and it from the same PC all the workarounds feel clunky. So not so much a new app but ways in which a good app can be improved. For example when the put the -packet_trace function in nmap it became much more useful for me than it had been and it was already da bomb.

      I can't open more than one trace per session.

      1. generates a complete protocol tree so that it can run the filter;
      2. generates the column data so that it can add a row to the display;

      and, as I remember from the last profiling runs done when running filters, that takes more time than does re-reading the raw packet data. A version of the Wiretap code to memory-map the capture file being read (with a mapping window so that files bigger than the amount of address space available for mapping can be read) might be interesting, although it wouldn't necessarily improve things much, as indicated.

      What you're asking for sounds more like the ability to insert notes into the capture file itself. Some capture file formats support that, as do the analyzers using that format (I think Microsoft Network Monitor might). Ethereal's native format (libpcap) doesn't; the next generation of libpcap is intended to be extensible, and one extension would be comment records with arbitrary text in them.
