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? When securing/testing/exploring networks (home or enterprise), what security tools/applications/functionality are lacking (or non-existent) in the open source world?"
Here comes the "THAT'S NOT THE PROPER USE OF BEGS THE QUESTION" people. Get over it. English changes.
Open source security tools are missing.. security holes?
Oh, wait, you probably mean stuff that actually works.
That's not how you use "begging the question"!
Thank you.

Are we searching around for a project to start? The best stuff comes when you're scratching your own itch.
You are not a beautiful or unique snowflake -- but you could be if you got off your ass.
Also important, if you don't think anything is missing, or even if you do, what software do you use for security purposes? Anything obscure but useful or unusual uses of common software?

...what security tools/applications/functionality are lacking (or non-existent) in the open source world?
How about an open source Security Information Management System (SIMS) Description, Article .
Something that lets us intergrate, collect, and correlate what the other great tools (Nessus, Snort, Nmap) find.
I've yet to find an open source tool that can show a "matrix" graph of source and destination talkers by MAC/IP/IPX name in realtime as found in Sniffer. Other tools show some of this information, but do not render the same graphical display (chords of a circle) as Sniffer.
With ethereal there's to do this with snapshots using graphviz, but not realtime...
I do not deploy Linux. Ever.
When we can create a truly fertile environment for elements like this in OSS, then we'll have arrived.
These tools could "leverage" existing security tools which exist in the open source world (stuff like tripwire for example) to get cross-platform support.
You don't have to just look at security, either; A multiplatform enterprise management suite with plug-in modules for filesystem, printing, security, scheduling, and good old monitoring would be a great thing to do for free. Software that does all that costs millions of dollars, single installs for sufficiently large sites can run upwards of US$10M.

webspy is what you're looking for. urlsnarf can also be used to grab requested URLs but doesn't provide the fun "surfing-along" feature.
If you are looking for a proven open standard methodology for performing security tests, then Open Source Security Testing Methodology Manual (OSSTMM) is the way to go.
In addition, there is the linux distro of Trinux, which includes most of the common linux open source security auditing tools.

It seems to be that people who make security tools don't open source them on the normal channels because they don't want 5cr1p7 k1dd135 stealing them. For instance, I'm currently working on an SNMP scanner to analyze a fibre channel network - no way am I open sourcing it; it shows entirely too many holes. *shrugs*

Besides, if the holes you find become fixed due to public notice, how are you going to exploit them in the future?

I use it every day all day long and could not do my job wihtout it. But I would really love a GUI better than ethereal for it. 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 am constantly trying to improve the security of my home network, and the available tools are pretty powerful. My biggest problem has been to find powerful reporting tools. I use iptables as a firewall, tripwire for intrusion detection, etc. But it's not always easy to see what's going on in the system. Tripwire produces decent reports; but there is no easy way (afaik) to get a list of intrusion attempts, network traffic, port scans, etc. Sure, the information is in the logs - but the log information is hard to parse and often not as complete as it should be.
Under capitalism man exploits man. Under communism it's the other way around.
A ton of tools are available for nix boxes, take a look at the live cd security distros. Tons of perl scripts or .c files. infosec geeks don't need fancy GUI's we need little scripts that can be piped or molded for different needs. look at all the tools that have been ported to win32 from linux/bsd like hping, nmap, nessus, ethereal, netcat, nemesis, datapipe, fport, lcrzoex, snort, etc. It's the closed source guys who need to get cracking. Look at Foundstone all they do is port stuff cause the win32 crap sucks. OSS tools are the ones leading the pack on this front. That being said perhaps Snort could be a bit easier/less prone to false positives, I couldn't grasp it completly until getting a book on it.

To my knowledge there is no, or perhaps very limited, support for the WPA standard. Granted, this isn't a tool, but it's security related.
Here's one I just thought of. Maybe it's been made, and maybe 16,000 people will point out why it isn't necessary or that it's built into find or emacs or something. Here goes anyway:

Write an app that takes a username as input and shows me all the files/directories that user can read or edit or execute. If I run it as root, it shows me All files. If run as me under my account, all of my files that that user could play with. For example:
shell% sudo fileSecurityCheck -www
will show me all files that are deleted when my webserver gets hacked.

"Begging the question" used to describe this alleged fallacy of reasoning is bad (modern) English. As a translation of "petitio principii" it probably made sense to 17th century British schoolboys, but "appeal to principle" is much better modern English.
A good reason to avoid the construction altogether is to avoid looking like one of the asshats who cites nizkor.org as an authority - or worse, drawing them out of their pedantic cubbyholes.

A tool for managing the various aspects of encryption on a system would be useful:
1- Setup and administration of VPNs (PPTP, IPSEC)
2- Administration of secure remote access (SSH)
3- Partition encryption
4- File encryption
5- Email encryption
YES there are bits and pieces, some distributions have more than others, but no control point for system-wide administration and enforcement that can be implemented across distributions.
Can You Say Linux? I Knew That You Could.
Most open source project focus on utility, not on appearance. The most powerful tools are often the simplest ones (in appearance). However, the ability to visualize and/or put a user-friendly interface is usually a good next step. Some may call this approach the "Microsoft dumbing down" approach, since it is Microsoft who usually put deceptively simple user-interface in front of a much more complex and powerful tool.
However, that doesn't mean these tools couldn't benefit from good visual front ends (and I'm sure people will point out there are plenty). Human's ability to make sense of well designed visual information (a la Edward Tufte) cannot be understated.
I also seem to recall reading a slashdot story a long while back about Infineon (I think) that had a hardware sniffer that is able to reconstruct TCP/IP traffic/session/connections that are captured, and it recognized hundreds of protocols/applications.
Bring all of that together: open source software being able to visually display security information in a meaningful way, using some kind of open standard like, say, OpenGL. Adding more to the existing foundation tools that we already have, that's where some contribution can be useful.
But that's just what I think, by no means do I think it's the best answer.
#5 is a Windows-only deficiency, but the rest aren't. I mentioned Antivirus software 3 times because I think it's at least 3 times as important as the others. As more and more (read: dumber and dumber) people migrate to non-Windows platforms, viruses and malware are going to start to be more of a problem for those of us on Better Platforms.
All's true that is mistrusted
I am unaware of open source software that meets the functionality of PWSEX or LC5.

Something that can premiscuously detail a LAN. It should use netcat, nmap, ethereal and the other standards to map, in real time, you LAN traffic. It should also have the ability to intercept and decode any stream on your network.
So, let's say Billy is reading Slashdot when he's supposed to be doing data entry. You see a red (for example) line leading from Billy's box to the firewall with the line labelled "slashdot.org" and the IP address. Click on Billy's box and "zoom" to focus the GUI to Billy and right click menu to "intercept and decode" to pop-up a konqueror window that follows Billy's URL jumps and shows you what he's reading. The same would be true of mpegs he's watching or mp3s he's downloading.
Other functions would be to show all nodes in the LAN as well as OS versions, all traffic in and out of each node, and any services running per node. Servers running things like ntlogon, apache or SMB would be marked as such. A "bookmarking" type feature could also be implemented as well as a sticky-note feature for notation and easy navigation.
You could call it knetsec, but I actually like a bastardization of that... Knutsac.

The above statement begs the question: "...what open source security tools are missing?"
No, it doesn't.
The truth of that statement does not depend on the fact that some open source tools missing. Therefore it is not an example of "question begging" (taking for granted exactly what you are trying to prove) at all.
It couldn't be jock itch.
It couldn't be an std.

Liberals call everyone Nazis yet they are the closest thing to it.
For MS software for example. A good anti-virus with an up-to-date library. This might actually be too much work for unpaid volunteers.
And a good disassembly program. Like IDA Pro. This is what the pros use to analyze viruses and the like.
Something like a kick-ass OSS IDA Pro will be needed in the upcoming OSS-DRM wars.
Pardon the spelling. It was never my strong suite:)
Being notified that a program is trying to connect to the network can clue you in that you have been infected by a worm, virus, trojan, or spyware. Sure, Linux has relatively few malicious programs now but in the future it may become a bigger target.

Forensics is still shrouded in mysticism and secret handshakes in the both the open and closed source worlds. EnCase is fantastic, but the cost is prohibitive, the other commercial products cater to law enforcement, efectively killing the divorce investigators and legal business use. The ones who will sell to anyone are not worth their exorbitant prices.
Autopsy/Penguin Sleuth Kit is great, but it has a long way to go to match the ease of use and reporting capabilities of EnCase.
The OS Forensic packages are labors of love to fix short commings or customize the tools for specific tasks. We need a OS Forensics Army Knife.
I want to be able to know what the recently fired employee was doing so I can make a case to the Legal Dept. There are many reasons to terminate an employee that do not "rise to the level" of prosecution, but certainly can result in Civil proceedings. I don't want to have to have a Windows box laying around for the eventuality of digging into ex-employee misdeeds.
I can also think of instances when "trusted" people jump ship unexpectedly, like when a senior developer resigns to take a position at a competitor. Wouldn't you like to be able to dig deep into the unallocated clusters of his HD?
Not exactly a security tool per-se, but some friends mentioned a screensaver that ran on linux and used etherreal or something similar to look for image files flowing by on the network, capture them and display them as a screensaver. A nice tool for a sysadmin to see what their users are looking at.
Anyone know the name/URL of such a beast?
Thanks!
Something I've started to see appearing are vulnerability management tools which combine asset/vulnerability management with workflow systems.
What does this mean in english?
Today, you scan your various class A/B/C's (with Nessus) within your company, and discover 300 vulnerable systems. You can generate a nice report, but not do much else without a lot of manual calling up of people and forwarding the report.
Instead, there are commercial tools available now that do a few things:
1) Classify IT assets and assign them to different groups (desktop team, unix team, database team) and how critical they are (carrying customer traffic, development servers, etc).
2) Individuals within each group can run ad-hoc scans of their team's systems, or alternatively await reports generated from scheduled scans.
3) Once vulnerabilities are discovered on each team's systems, they are notified and provided with a web-based system to update and close off vulnerabilities when patched. It is then possible to see from a high level, which teams have the most vulnerable systems, and how effective they are in managing security on their part of the network.
Those are the kind of products that the company I work for are now investigating, as for once, they provide solid metrics to demonstrate to management that we're doing our job.

You aren't a pedant. There are just lots of people who like making themselves look stupid while trying to look smart.
A tool that takes virtually any input (Windows Event Viewer thingies, Unix Syslogs, Router Syslogs, Squid logs), and can correlate all of the events.
I know there's a Cisco-ish product that you can do this, and it monitors for certian 'bad' things happening on your network, and can send emails to a certian person or whatever.
Although, given the state of things, the ability to look back and see the state of the network at a given point to track down a user would be mighty handy as well. (When a user logged on, which URL's they accessed, when, what else they did, and so on)
Certain of the app server vendors provide functionality through their console products, but it would be nice to have a vendor neutral product that would let me browse/edit identity data regardless of the source (LDAP, the OS, whatever), let me map application roles to the environment, and let me examine and interchange various policy files, maybe using XACML as the lingua franca. Maybe also something that would keep track of JAAS login modules and JAAS config files.
Like is said, a bit boring, but it'd make it easier to assemble and deploy applications, and to move applications between app servers.
Yeah, hi.
The use of "begs the question" that is correct sounds stupid.
The incorrect use of "begs the question" sounds good.
And, as a poster above pointed out, language changes.
Until someone gives me a good example of the phrase "begging the question" that doesn't sound totally idiotic, then I'm not going to respect you people.
It's like the people who insist that everyone is using the word "Hopefully" incorrectly, as it is an adverb. Stephen Pinker gives this example of its "correct" usage as an adverb:
Hopefully, Jim reached his arm over Sarah's shoulder.
(Okay, that's not the exact sentence, just a paraphrase).
"Nice" used to mean exact. It doesn't mean that anymore, and no amount of trying to "share knowledge" with others about its "correct" meaning is going to make you any less of a pedant.
Also, just out of curiosity cuz I don't get it, in the phrase "begging the question", who/what is doing the begging, and what exactly is the question?

I am looking for a tool that supports both Windows 2000/XP and Mac OS X that does on the fly encryption for removable USB memory sticks.
I know of platform-independent tools like PGP, but after decrypting, unencrypted data would sit on the thumb drive. If I was interrupted after decrypting or (more likely) forgot to encrypt the file again, unencrypted data would sit on the drive.
I know of Mac OS X's encrypted dmg files, but Windows has no way of accessing them. I would use one of the countless number of Windows-, Mac-, or Linux-proprietary third party "put your passwords here" tools for doing encrypted files, but all that I know of are platform-specific.
So what am I looking for? Something that has Windows and OS X clients that I could put on the thumb drive, along with a file of arbitrary size containing the encrypted data. After authenticating with the software, one of the following would happen:
(1) either the software mounts the encrypted file as a disk drive just like daemon-tools mounts a CD image in Windows, or OS X mounts a dmg file
(2) or the software includes a 'secure' text editor that can edit the encrypted file.
Either way, the software (1) sits on the thumb drive and (2) provides on-the-fly encryption so the data on the thumb drive is never unencrypted.
I'm willing for this to be horrifically slow as I would be storing mostly text on such a system, but supporting at least recent Windows and Mac OS X is important to me. I run Linux on servers/gateways but prefer Windows or OS X for my primary desktop/laptop machines.
I would be willing to pay for such a product, but I don't trust closed-source encryption products. Please let me know if you have heard of such a product!
Incidentally, PQI makes very very small thumb drives. Froogle for 'PQI intelligent stick.' Their USB1 model has a write-protect switch, but their USB2 model does not. (I am not affiliated but have bought, used, and liked their product.)

... application policies. Example: set a maximum security policy for each app and, if the app tries to break it, let the user decide what to do. Example: web browser. Tries to connect to the web: user selects to always allow that or to enter more specific rules. Tries to read from disk other files than those which are its own: user selects what to do. You could restrict browser access to a download directory. No viruses may get in and no browser bug may generate a security hole.
A bit like Symantec's firewall (as far as I can remember, but not limited to network access).
I should also be able to set up a special security directory where I store secret information. Any app access files in that directory, will, during their session, not be allowed to write any data or access the network or other data ports.
Just let each app run under its own policy. That would make Linux even more insensitive in regard to viruses and other malicious things like backdoors.
As far as I know SELinux is some sort of that. But as far as I know there are nice user interfaces missing that allow to interactively (and on demand) change the policies.
I played with an old-old-old demo version of NFR years ago and wanted a similar after-the-fact investigative tool, so I wrote my own. I record data about every single packet going to or from the Internet and feed it into a MySQL database. A web front-end supports queries against the DB, I can do more complex ad hoc queries from the MySQL prompt, and I have oodles of perl scripts that run analyses against the flat log files it generates. I've thought about asking my employer, on whose time I more-or-less developed it, about making it Open Source, but haven't had the impetus to actually do it. It's a great tool, and I'd be interested if there's something similar that's farther along.

The phrase "which begs the question" has always - in my Australian vocabulary - meant, "makes obvious and unsupported assumptions," or "leaves obvious questions to be asked."
For example, if someone is demonstrating a new space-alien repellant, the demonstration itself would beg the question, "which space aliens?"
Or someone proclaiming that a particular person is an "unlawful combatant" begs the question of what exactly defines a "lawful combatant"?
Ultimately, to "beg the question" means that you leave obvious questions unanswered. Sometimes this is the aim - make people ask a question that your political opponents don't want asked.

Based upon marketing hype, my management chain insists on using ISS's Internet Scanner (www.iss.net) to perform site-wide security scans and do vulnerability assessments. Nessus just simply isn't as feature rich as Internet Scanner. IS searches for thousands of vulnerabilities, and they are constantly adding new checks that can be dynamically loaded into the scan tool. The scans are highly customizable. The only problems are the tool can only run on a Windows server (i.e it can scan any network device including unix, printers, and Cisco), its a huge resource hog, and GUI only.
I'd love a nice, easy command-line based unix based system that has all the functionality of ISS, including the nice HTML output. The problem is, of course, that ISS has a huge head start.

yes, I agree completely. I revised my opinion in a later post after doing some more digging. Thanks for clarifying.
Metasploit (http://www.metasploit.com) has a real neat project going. I know I use it.
We need more open source tools that act as front-ends to monitoring and operations applications, glue to sit between the 24x7 security/network operations staff and highly advanced applications and devices which are designed for engineers and architects to manage.
Your typical 24x7 staff aren't experts - so we need expert systems to make them more effective.
An example is IP Blocker where you get a system set of Perl scripts that front-end changing the border router access control list.
Many of the procedures and functions we perform to ensure security across our networks can be automated, and it is these areas that need the most work today. Another example would be a script that checks an IP address on your network against your inventory records, vulnerability databases, and other criteria to display an exhaustive history for the device as known by your organization. How many times have you got a Snort or other alert for an IP on your network which you have no idea who owns or what it does

One thing I see missing is a good network / host discovery tools with a rich feature set. Like being able to automagically map out a TCP/IP network via SNMP querying "seed" routers, and/or by passively observing network traffic, then being able to collect further information on each host through port scanning or SNMP walking. The biggest problem I see is there's alot of great tools out there, just none of them that does everything without having to jump between multiple programs. And of course, it would be with a curses based gui :)
Solarwinds has a tool called Sonar which does the "seed" router snmp-based discovery. They have some other nice tools too, but it still takes alot of tedious switching between applications to get all the information i'm looking for.

McAfee's DAT files to catch this one came out 2 1/2 days later, on the Monday morning (UK time).
Apart from the Nimda outbreak of 2001, this year is the only time I've seen viruses arrive at our email gateway (thanks ClamAV) before our official antivirus software updates catch them. Netsky, Bagle, and Zafi.b were all caught by ClamAV before McAfee had released DAT files for them.
I'd recommend defense in depth, using multiple virus scanners. We scan all incoming (and outgoing) emails with ClamAV, Bitdefender (free for Linux boxes), and McAfee's uvscan.
It's way too easy to fall into the mindset which says "we have antivirus software everywhere so we're safe". There will ALWAYS be a window of vulnerability between the release of a new virus and the availability of detection patterns. And don't forget that a lot of Windows viruses/worms disable any antivirus software they find running.

If all viruses were based on security holes in software, you would have a point. But they aren't.
Many (most?) malicious programs do not exploit any software security holes; they just rely on stupid or careless users. The point of something like Norton Antivirus is not to make up for security holes in Windows/Office/whatever, it's mostly to mitigate users' carelessness or naivete.
Can your user account on your computer send mail? Connect to an arbitrary Internet host? Hell, spawn a process? If so, congratulations! you have just become a potential target of malicious software. Proprietary AV software doesn't particularly look for holes in OS's and applications, it looks at files and running processes for A) known signatures and B) known malicious behavior. I think an open source AV solution could potentially do that better.
All's true that is mistrusted
I know ethereal has a leg up on APriori-based protocol detector but I sure like to see that extended to other forms of Layer 2 (other than Ethernet DIX version 2).
I've been trying to find an authenticating/logging telnet proxy to work around this, but it's impossible to find, so I'm facing writing one myself.
Note that you'll still have to "End Task" wscript.exe to kill it, but at least it goes to sleep and doesn't use any CPU in between times.

That's two people so far who seem to have *.vbs associated with wscript.exe ... Slashdotters, no less...
Here, see, I have a lovely picture for you...

- configure what fields are logged,
- configure what fields are shown to me,
- configure what records are shown to me,
- configure if conversion from raw to symbolic values happen or not (e.g., hostname lookup, services lookup, etc.),
- save those view configurations and be able to reuse them later
- auto update with new log entries (like less -F, but with the above features)
Checkpoint's FW-1/VPN-1 is a dubious product in terms of security and licensing woes, but SmartTracker is an interesting log viewer.Anybody got similar functionality for iptables? I've looked around, but found nothing. I'm even now hacking new ulogd plugin to give me at least feature (1).

Real students of linguistics and languages do not take issues with things like this, only elitists and grammar Nazis do.
The statement "Languages evolve, but that fact is too often used as a cop-out for being too lazy to learn correct use of a language." is utterly nonsensical, because there *is* no correct use of a language. A language is a construct to serve the people, and as people change, so must the language. Languages evolve over time, and should be treated more like a living organism than a rulebook. The only "correct use of a language", by definition, is the way the majority of the populace is using it. In this case, the majority of the populace uses "begs the question" in this sense, so it is perfectly valid, and is not any less so than any other commonly used phrase.
Oddly enough I know the guy that wrote Ethereal, even though I don't use the program. He's in my Linux User Group. Great guy, he has helped me w/ numerous problems as I switch to Debian.
Anyway, have you asked for these features? Ethereal is under constant development. I think that as long as the new features don't slow the program down and they add necessary functions, they might get added.

If you're going to be a grammar nazi, try to avoid stupid typos you dumb fuck.
If you're going to flame somebody else for posting a grammar flame with incorrect grammar, please make sure your own grammar is correct. In particular, 'nazi' should be capitalized, and there should be a comma after 'typos'.
Just write your virus in Perl - portability problems greatly reduced.
Windows Installer (MSI) packages use WSH scripts extensively. Disabling them completely will remove some fairly well-needed functionality from the OS.

I don't know... I have WSH disabled here...
Actually I don't know whether my XP install has it on, since I don't use it on the network (1% XP, 99% Linux, last XP boot back in April...) and while I vaguely remember turning WSH off via some checkbox some time back, I don't remember if it was this laptop, or my 98 box under the desk... So I don't know if disabling WSH cripples MSI... But I thought that I had, and without issues...
Doesn't MSI parse the scripts directly? I'm sure I installed office on a machine with Scripting Host disabled once... I must doublecheck this sometime...
Oh well, you learn something new every day...
