Top Level Domain (TLD) Lua Parser for Logs

Written by Admin | Apr 16, 2018 4:00:00 AM

The TLD parser has been updated to now deploy on Log Decoders.  

The parser looks for the following keys from log devices to parse out the same information as packets:

  • Alias.host
  • Host.src
  • Host.dst
  • Domain.dst
  • Domain.src
  • FQDN

Which writes out information into:

* alert.id - mapped to risk meta
* analysis.service - hostname characteristics
* cctld - (nonstandard) (optional) country-code top level domain, e.g., www.amazon.co.uk -> co.uk
* sld - (nonstandard) (optional) second level domain, e.g. www.amazon.co.uk -> amazon
* tld - top level domain, e.g. www.amazon.com -> com

When searching for Lua and Log in the RSA Live deployment screen you will see the following:

And linked dependancies:

So this is a really simple method of getting nwll.lua deployed to a log decoder if your custom parser requires that library (PaloAlto URL.raw parser for instance).
