It doesn’t appear that there is full support for DNSSEC RR types in the current release and I’m >looking for the best option in the meantime.

For example, answers that include RRSIG’s will produce a vector similar to [“”," > "] with a corresponding event in weird.log of “DNS_RR_unknown_type”.

In protocols/dns/consts.bro I see type 46 is included in the query_type map but based on the >variable name I assume its not applied to answers?


Hi Dave,

There were some recent commits done to support these DNSSEC RR types parsing in Bro: RRSIG, DNSKEY, DS, NSEC, NSEC3.

If you want to give it a try, it’s available in dev/2.7 branch or a forked branch from 2.5.4 at following:
https://github.com/fatemabw/bro/tree/master (bro 2.5.4 with dnssec)


Apologies for the delay.
