A handful of people connected to the "Maritime World" have reached out to me regarding cybersecurity and their concern of developi certain systems being connected through Internet. I have little to no experience working in the maritime world, and I haven't worked professionally with cybersec other than hardening of operating systems following various benchmarks.

I want to learn more about infosec/cybersec in general, and especiall in the maritime. I therefore humbly ask for your experience, advice or external resources.

Hi, I'm looking for a way to rotate SSH-keys in an infrastructure. I have no experience when it comes to rotating SSH-keys.

Today I use SSH Key-based authentication to authenticate to my servers, tho I have been wondering if I should take a look SSH Certificate-based authentication, or if it is just an "idea" that seems nice.

This is far from a well structured question, but I appreciate anyone who contributes.

Thanks.
