What it helps you do
Help a team pick a small, ordered set of hygiene practices - inventory, access, patching, logging, backups - without waiting for a complete management-system project. Meridian Space & Robotics can use IG1 as a starting discipline for the telemetry VPN, identity, and backup work in the foundations path.
A useful way to begin
- Inventory internet-facing appliances and admin identities before expanding into later IG2 items.
- Assign each chosen Safeguard an owner, a first evidence source, and a review date.
- Treat IG1 as the default starting set unless a regulator or customer contract names something else.
- Revisit exceptions, such as a delayed VPN patch, as IG work rather than silent skips.
What good evidence looks like
For one IG1-relevant safeguard, such as inventory or secure configuration of the VPN, a policy or screenshot that names who owns it, the last review date, and the date an exception expires. A checkbox spreadsheet with no owners is not that record.
Other records you might already have
- An owned inventory of Chronos Hub, the Propulsion testbench, the orbital telemetry edge, and the VPN with last-verified dates.
- A patch exception ticket that names the compensating geofence and its expiry.
Common misconceptions
IG1 done means Meridian cannot be hacked.
Implementation Group 1 is a foundational hygiene set. It is a starting discipline, not a promise that attacks will fail.
Finishing CIS Controls means we are CSF compliant.
CIS safeguards and CSF outcomes are related maps. Completing one does not complete the other, and neither is a certificate.
Every safeguard applies equally to every organization size.
Implementation Groups exist so a small team can start with IG1 and add depth when the environment is more complex.
