Hi,
For those of you caring about security in ROS and in robotics in general, the following article might be of interest: robot cybersecurity, a review.
Shortly, the article attempts to answer two questions: what’s the status of cybersecurity in robotics? and, how can we best improve cyber-resillience in robotics? For that, the status of the robot cybersecurity field is reviewed considering three sources of data: 1) recent literature, 2) questionnaires performed in top robotics forums (this includes data collected in the community through past events and surveys) and 3) recent research results in offensive robot cybersecurity.
The article makes a number of observations based on the data available (thanks to all of those who participated in the data collection 
). Here’re are some of the ROS-related ones:
There’s a gap between the expectations and the actual investment, which suggests that cybersecurity actions in robotics will grow in the future for the ROS community.
The lack of robot-specific security measures (36%) and offensive assessments (26%) can be interpreted as an indicator of the maturity level of the technology when compared to other sectors (e.g. IT or OT) where these practices are common and specialized.
For both ROS and ROS-I groups, (security) mitigations concentrate mostly on the perimeter.
