Overview of DAS Custom System
The Styra DAS Custom system type is used when other system types fail to meet your requirements. It helps you manage any other real-world system that has been integrated with OPA. For example, you can govern public cloud resource configuration, control who has SSH access to a Linux server, or define the authorized readers and writers of Kafka topics.
For Custom systems, you can configure the DAS so that it understands the decision log format to display and search decisions accurately. For more information on configuring decision logs, see the Decision Log Configuration documentation.
For more information on how to use Styra, OPA, and Linux Pluggable Authentication Modules (PAM) to enforce fine-grained, host-level access controls over SSH and Sudo, see the Custom system type tutorial.
