  SROS is a proposed addition to the ROS API and ecosystem to support modern
cryptography and security measures. An overview of current progress will be
presented, rationalizing each major advancement, including: over-the-wire
cryptography for all data transport, namespaced access control enforcing graph
policies/restrictions, and finally process profiles using Linux Security
Modules to harden a node's resource access. By making the community aware of
the vulnerabilities in ROS, as well as the proposed solutions provided by SROS,
we intend to improve the state of security for future robotics subsystems.
