Mojave CIS Benchmark

CIS has Mojave benchmarks out? I thought HS was the latest for some reason.

I know that a lot of emphasis is placed on the CIS benchmarks as they represent a consistent, respectable set of "standards" for organizations to follow. However, CIS is taking about a year after the release of each macOS to publish the document covering those settings (High Sierra v1.0.0 is dated August 31, 2018; macOS Mojave released on September 24th). So while I understand security teams wanting to "check the box" for compliance, there isn't a CIS document that exists yet for Mojave.

I've ended-up building my own "macOS security baseline" document for internal use that is based on the High Sierra CIS document (and will be updated whenever the official Mojave guide is published) and testing each feature against the updated OS, figuring out what is broken, and researching how to fix it. I also spend a lot of time pouring over security talks from various conferences, WWDC, Apple developer and administration documentation, etc. to make the most of securing the platform.

Get the full CIS docs, I think you can get the word doc version or the PDF version and it shows.

1. How the CIS test is executed in code.
2. How to remediate with an example sometimes with code.

With both of those examples, it's usually sort of easy to appease "super smart" security groups.

Is there still no CIS Benchmark for Mojave? None for Catalina either?

Maybe we should look at another benchmark since CIS is clearly ignoring macOS. What other options are people using?

FWIW, CIS isn't "ignoring" anything... the CIS group is a volunteer group who write the benchmarks in their spare time. (disclaimer, I helped write the 10.8, 10.12 and 10.13 benchmarks).

Due to a few factors, I haven't been involved in any of the CIS effort since 10.13, but if you want it done faster, help them! It was usually only 4-5 people working on it at a time, and just not enough resources to go around.

FWIW, for those who have access, DISA is also a very good option (DOD), but doesn't run any faster than CIS normally, and that one has "corporate" backing (aka, DOD sys admins assigned to work on it). One huge difference between the Mac and Windows CIS schedules is Microsoft's involvement, vs. no "official" support from Apple (although there are usually a few apple employees working on the CIS, but again, in their spare time as volunteers).

Don't think STIG released 10-14/10-15 either.

Apple OS X 10.13 Security Technical Implementation Guide

Once jamf | PROTECT is released (and allows us to control audit values) we will all be in a better place.

Another approach that should be valid if you have a reasonable ITSec. group - fix your documentation to simply say that your baseline is the "Current CIS benchmark" and stop listing version. Then for internal documentation, write up a reasonable approach stating core security controls you require to be in place, and allow new OS version on a provisional basis "until such time as CIS implements an updated benchmark". Most info sec departments are all about managing risk. Having things written well, with solid test plans, etc. give them what they need to help you. In past roles, we usually had a set of "core" controls that we required to be implemented for new OS's, and as long as we could guarantee those, we were allowed to run newer OS's. Depending on the size of your .org, if you're purchasing systems regularly you're more or less tied to Apple's OS release schedule, and can't handicap yourself by being dependent on a benchmark written for a specific OS release which may or may not be current.
