       hlbrw - assistant to help make new rules to HLBR


       hlbrw [option]


       HLBRW  is an acronym to Hogwash Light BR Watch. The intent is provide a
       tool to help make rules to HLBR ( In others  words,
       HLBRW was made to be used by HLBR users needing make new rules (it will
       require some expertise about HLBR, TCP/IP protocol  suite  and  regular

       HLBRW  is  a  script  started  by iwatch (a system events watch program
       available at when the HLBR events log is
       modified.  The  concept  is  very single: if the HLBR log was modified,
       then a knew attack was blocked.   But  the  attacker  can  make  others
       subsequent  actions  unknown by HLBR. Then the iwatch running as daemon
       will start HLBRW and it will co-ordinate a tcpdump  session  to  record
       the posterior traffic generated by attacker IP for some minutes. If the
       recorded traffic isn’t relevant (without  a  push  in  TCP  or  another
       relevant  protocol),  the  created  file  will be deleted. Based in the
       recorded traffic, the network security manager will can make new rules.

       HLBRW is part of the HLBR project.


       -h, --help
              Shows this help.

       -v, --version
              Shows the HLBRW version.

       none   If  called  without an option, runs HLBRW main function. This is
              an iwatch action.


       To see a dump file content, use the tcpdump:

       # tcpdump -n -S -s0 -A -r /var/log/hlbrw/<file.dump>

       You can use the wireshark too.


       You can send good rules to Your rules will be
       analysed and if relevant to project, will be put in next version of the
       HLBR project.  Please, be selective and don’t send imperfect or useless


       /etc/hlbrw.conf - Configuration file.

       /var/log/hlbrw/* - Recorded traffic in tcpdump format.
