OPA for the cloud natives
#1about 3 minutes
Decoupling security checks from application deployment
Traditional embedded security checks are hard to audit and maintain, so decoupling them as policy-as-code enables continuous validation and simplifies compliance.
#2about 3 minutes
Shifting security left to prevent incidents before deployment
Proactively catching security violations in the CI pipeline is far better than reacting to incidents in production, moving beyond tribal knowledge to codified policies.
#3about 3 minutes
Introducing the Open Policy Agent (OPA) and Rego
OPA is a CNCF graduated project that provides a unified way to enforce policies across APIs using a custom declarative language called Rego.
#4about 3 minutes
Writing basic Rego policies for common use cases
Simple Rego policies can enforce rules like user data access control, manager hierarchies, or ensuring Kubernetes pods use a trusted container registry.
#5about 5 minutes
Using the OPA Playground to test and debug policies
The OPA Playground provides an interactive environment for writing, testing, and debugging Rego policies against sample input data, such as Kubernetes configurations.
#6about 2 minutes
Exploring OPA deployment patterns and advanced use cases
OPA can be deployed as a Go library or a sidecar daemon, enabling advanced use cases like validating Elasticsearch queries to enforce fine-grained data access control.
#7about 3 minutes
Automating infrastructure compliance with CIS benchmarks
OPA policies can codify Center for Internet Security (CIS) benchmarks to continuously scan Kubernetes clusters for misconfigurations and security vulnerabilities.
#8about 3 minutes
Addressing performance and adoption challenges with OPA
While powerful, OPA adoption can be hindered by the complexity of writing performant queries and the learning curve associated with its custom language, Rego.
#9about 3 minutes
Answering audience questions about OPA and Rego
The Q&A covers Rego's support for JSON and YAML, deployment options on bare metal or VMs, and potential integrations with APIs like GraphQL.
