Yes, CPS architecture documentation can be found @ https://docs.onap.org/projects/onap-cps/en/latest/architecture.html

*Page is being updated for the next release to reflect that the architecture diagram reflects the latest release. (https://gerrit.onap.org/r/c/cps/+/133557)

The ONAP architecture diagram (London-R12 Architecture diagram) is displayed on Configuration Persistence Service Project wiki as part of explaining the project's concept

Please refer to the latest ONAP architecture diagram.

CPS don’t have security requirements apart from the authentication on our rest API wherein username and passwords are configurable

Configuration Persistence Service Project#CPSSECURITYREQUIREMENTS

 Please add a statement about this to the end of your architecture document (or in another wiki page), with a heading such as "CPS Security Requirements."

Please refer to the latest ONAP architecture diagram.

Please elaborate this statement: "Usernames and passwords are configurable by the clients via configuring the application .yml file".

Expectation: passwords are not in yml file. The yml should point to user store (e.g. LDAP or K8s secrets).

Configuration Persistence Service Project#CPSSECURITYREQUIREMENTS

CPS don’t have security requirements apart from the authentication on our rest API wherein username and passwords are configurable.

CPS has no logging of sensitive information such as usernames and passwords in plain text. The log files are only accesible withing the  authorized users of the application deployment.

CPS is in the process (as part of ONAP service mesh implementation) of migrating to service mesh, currently CPS application is fully-compatible with all the requirements, to provide encryption in transit to avoid unauthorized accesses and data breaches.

CPS does not run docker containers or services as 'root'.

Please add these statements to a new Security Assurance section just after: Configuration Persistence Service Project#CPSSECURITYREQUIREMENTS. — these statements are the same as under security requirements

Also add statements that indicate how you protect your username and password configurations. (See other questions on hashing of secrets, use of crypto and permissions on files.)

CPS does not have a UI and does not use javascript

The application uses Swagger for RESTful API, wherein it is set that Authorization headers are required for accessing API documentation.

When CPS is run with docker, the services use usernames and passwords that are stored as environment variables.

While for testing purposes, all credentials are hard-coded, for deployments, CPS uses K8s secrets which are generated and stored as the application is deployed.x

How are usernames and passwords stored?

Are passwords stored hashed where CPS acts as an authenticator?

Please refer to comment above in Documentation security.

CPS is compliant and compatible with the ongoing service mesh implementation (see https://gerrit.onap.org/r/c/oom/+/124287) for ONAP. 

CPS service port names has been changed to include http in name.
