OpenSDP

A proof of concept Software Defined Perimeter (SDP) implementation using OpenSPA for service hiding.

opensdp

How It Works

Currently being a PoC, OpenSDP supports only service discovery for OpenSPA protected services.

  • Each service is protected by an OpenSPA server
  • Clients not knowing where OpenSPA hidden services are contact the OpenSDP server for service discovery over mutual TLS
  • Clients are then free to perform the OpenSPA handshake with all services that they are authorized

opensdp-detailed

Currently it's only possible to define services and the clients ACL using a series of YAML files. This is planned to change in the coming releases.

Client Usage

Currently there are two commands: services and access.

Services

Returns a list of authorized services.

Access

This command is used to acquire access to a service. You can use it by specifying the service name, eg. ./openspa-client access example-www. It is also possible to acquire access to all authorized services (returned using the services command) using the command line flag -a.

Setup

A tutorial how to setup OpenSDP with a working OpenSPA installation is available here.

TODO

  • Add logging to server
  • Add timeout if HTTP request is taking too long
