Introduction

The tags beginning with cloud.aws.waf identify events generated by the AWS Web Application Firewall (WAF).

Valid tags and data tables

The full tag must have 4 levels. The first 3 are fixed as cloud.aws.waf. The fourth level identifies the events subtype.

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

Product / Service	Tags	Data tables

Product / Service	Tags	Data tables
AWS Web Application Firewall (WAF)	`cloud.aws.waf.logs`	`cloud.aws.waf.logs`

For more information, read more about Devo tags.

How is the data sent to Devo?

Logs generated by AWS WAF service can be sent to AWS CloudWatch Logs, S3, and Kinesis Data Firehose services.

The preferred methods are using the first two services as destinations. In these cases, Devo AWS collector can be used for gathering, properly tagging, and securely forwarding these logs to Devo.

Logs sent to Kinesis Data Firehose can be properly tagged using an AWS Lambda function and forwarded to a Devo HTTP(s) endpoint (as an alternative, a Devo Relay deployed in an EC2 instance can be used for tagging and securely forwarding events using Syslog protocol).
