However, without proper management over these resources, your mesh\nmight expose security vulnerabilities. Integrating\n[Policy Controller](/anthos-config-management/docs/concepts/policy-controller)\nwith Cloud Service Mesh security policy constraints can help enforce your mesh\nwith security best practices and prevent vulnerabilities.\n\nThis page assumes you are already familiar with\n[policy constraints](/anthos-config-management/docs/how-to/creating-policy-controller-constraints).\n\nConstraints templates\n---------------------\n\nWhen you [install Policy Controller](/anthos-config-management/docs/how-to/installing-policy-controller),\nselect **Install default template library** . This option deploys\nall of the Cloud Service Mesh security policy constraint templates needed for your\nmesh. For a full list of the Cloud Service Mesh security constraint templates, see\nthe [Constraint template library](/anthos-config-management/docs/latest/reference/constraint-template-library)\nand look for templates that are prefixed with `Asm`.\n\nConstraints bundle\n------------------\n\nWe offer an out-of-box constraints bundle for Cloud Service Mesh security policy.\nFor the bundle details and instructions, see\n[Using Cloud Service Mesh security policies](/anthos-config-management/docs/how-to/using-asm-security-policy).\n\nTo follow a tutorial that shows you how to apply this bundle, see\n[Strengthen your app's security with Cloud Service Mesh, Config Sync, and Policy Controller](/service-mesh/v1.19/docs/strengthen-app-security).\n\nAdd-on constraints\n------------------\n\nSome constraint templates are installed with the default template library,\nbut not included in the security policy bundle. These constraint\ntemplates serve specific use cases, and you can configure your own constraints:\n\n- [AsmAuthzPolicyDisallowedPrefix](/anthos-config-management/docs/latest/reference/constraint-template-library#asmauthzpolicydisallowedprefix)\n- [AsmAuthzPolicyEnforceSourcePrincipals](/anthos-config-management/docs/latest/reference/constraint-template-library#asmauthzpolicyenforcesourceprincipals)"]]
