Introduction

The tags beginning with waf.signalsciences identify events generated by Signal Sciences Web Application Firewall.

Valid tags and data tables

The full tag must have 3 levels. The first two are fixed as waf.signalsciences. The third level identifies the type of events sent.

Technology	Brand	Type	Subtype
waf	signalsciences	request

These are the valid tags and corresponding data tables that will receive the parsers' data:

Tag	Data table
waf.signalsciences.request	waf.signalsciences.request

How is the data sent to Devo?

Logs generated by Signal Sciences Web Application Firewall are forwarded to Devo using a proprietary Apache nifi collector. Contact us if you need to forward these events to your Devo domain so we can guide you through the process.

Log samples

The following are sample logs sent to each of the waf.signalsciences data tables. Also, find how the information will be parsed in your data table under each sample log.

waf.signalsciences.request
