pattern database : first feedback and thoughts
Hello, I have start to play with pattern database. It is a very good starting point to do alerting when syslog-ng finds some logs belonging to (for example) security class. 1. Bug The current online pattern db snapshot provides the system-apache2.xml file. This file is not in a xml format but is just a set of log messages (it seems). 2. Class Can you tell us on what kind of criteria is used ti choose the class value (for example : system vs security class) of a particular log entry ? 3. Pattern database contribution / management / delivering Despite a big effort from Balabit (thanks for it !) to deliver an impressive first release (8000 log messages, 200 applications), I am sure that a community effort is the only way to maintain a good quality level of this database. You release the pattern database under the CC by-nc-sa licence. It is a very good way to start a community effort. In order to build a community around pattern database, I think some interesting points may be : - Having a dedicated DNS name and website (logpattern.org is available). Balabit can be of course the main sponsor of the website. But to be able to attract people and even more other companies for database contribution, I think all the communication / site management would have to rely on individuals and not on Balabit company. - Providing open log entry submission process through multi ways (web form, (D)VCS or bugreport system) - Providing a regular (each week, month or three months for ex.) database snapshot release cycle. If you want some help for the website, I can be involved :-) Thank you very much this pattern database effort :-) Christophe -- Christophe Brocas CNAMTS/DDSI/DSEC 12, allées Haussmann 33300 Bordeaux fixe : +33 (0)5.57.85.53.55 mobile : +33 (0)6.77.05.19.01 fax : +33 (0)5.56.39.84.48 keyid : 0x237E9DB2 ***************************************************** "Le contenu de ce courriel et ses eventuelles pièces jointes sont confidentiels.

You're right, I'll ask the guys to correct it.
2. Class Can you tell us on what kind of criteria is used ti choose the class value (for example : system vs security class) of a particular log entry ? AFAIK, there is no fixed rule: logins, access control messages and the like went to security, while more regular messages to the system class. But with the introduction of tags, I think the classes will become less important.
3. Pattern database contribution / management / delivering Despite a big effort from Balabit (thanks for it !) to deliver an impressive first release (8000 log messages, 200 applications), I am sure that a community effort is the only way to maintain a good quality level of this database. That's our opinion as well.

In order to build a community around pattern database, I think some interesting points may be : - Having a dedicated DNS name and website (logpattern.org is available). Balabit can be of course the main sponsor of the website. But to be able to attract people and even more other companies for database contribution, I think all the communication / site management would have to rely on individuals and not on Balabit company. - Providing open log entry submission process through multi ways (web form, (D)VCS or bugreport system) We are currently working on moving our website to a new portal engine, and also on creating a community site for patterndb where you can create, check and upload patterns, test your logs for patterndb coverage, interact with other users, etc., but that won't be ready for a few months. Whether this will be an individual site or part of the BalaBit site was not decided yet.
- Providing a regular (each week, month or three months for ex.) database snapshot release cycle. Snapshots will be available regularly once the site is up. Currently we did the initial snapshot so you can see what it will be like, and start using the new database format. Of course if we have some time to create some new patterns, or receive some from other users, we will release it ASAP.
If you want some help for the website, I can be involved :-) Thanks a lot :)
