On page 37, DHS instructs analysts to accept invalid SSL certificates forever without verification. Although invalid SSL warnings often appear in benign situations, they can also signal a man-in-the-middle attack. Not a good practice for the security conscience.
I think that’s grounds for termination by incompetence for whomever was behind that. DHS Phishing attack anyone? I’d expect better practices from a local library branch.
That said, it’s yet more proof that SSL as a form of identity verification just doesn’t work.
