Re: Cybersecurity and Infrastructure Security Agency(CISA) Cyber Hygiene scan services

[Sean Hagan <sean.hagan () ALASKA EDU>]

Vince - We've used the Cyber Hygiene (CyHy) service at my previous
institution for about 5 years - it's been a great resource to supplement
internal scanning.  At my current institution, we signed up two months ago
and CISA was very prompt in getting things setup and the reports are just
as useful (if not moreso, given our limited internal capabilities).

As Andrew points out, there is a related free service from CISA - WAS, or
web application scanning.  You may want to consider signing up for it since
it's free and focuses on different vulnerabilities.

One thing to plan for - how will you share detected vulnerabilities
internally?  The PDF you'll get from CISA is password protected and
includes a number of appendices with attachments, and since they're likely
scanning your entire external address space, that will necessarily
encompass devices managed by multiple different people/groups/departments,
most of whom likely won't be on the distribution list for the CyHy report.
I don't have a good answer for you, since my previous institution was small
enough and our internal scanning had sufficient overlap that there were few
issues in communicating detected vulnerabilities.  My current institution
is so large and distributed that we haven't yet come up with an effective
way to share this information, but I'm actively working on it.

Andrew - You should definitely ping CISA again - we had our first report
within 4-7 days of completing and submitting the paperwork, and we also
have a /16.
