In our defense, it’s because we’re expected to give everything a cert but often have no say on the security and cryptography capabilities of what’s brought onto the network in the first place, nevermind the manpower and time to build such an automated solution internally. Execs bringing in MFPs that don’t support TLS, PLCs that require SHA-1, routers with a packet buffer measured in single-digit integers but with a J…
Don't take this as a snarky comment, but that sounds quite literally as "skill issue". Not in you personally, but in the environment you work in. > PKI isn’t a solved problem. PKI is largely a solved issue nowadays. Software like Vault from hashicorp (it's FIPS compliant, too: https://developer.hashicorp.com/vault/docs/enterprise/fips ) let you create a cryptographically-strong CA and build the automation you need. I…
How do you do this on a proprietary device from the late 90s that runs a WindRiver VXWorks RTOS with 1 MB of SRAM? The updated (full color!) Panelview HMI is running Windows CE 6.0, so it's perhaps more likely to be compatible, but I don't think the same group policies exist on that platform.
The masses can do it in an afternoon because they can choose to only install modern equipment that's compatible with the new requirements. Some of the "heavy iron" castings for the machines we have to work with were built more than a century ago, and only later automated with tubes and relays, and then again with the first PLCs that could do the job. But now "SSL everywhere" policies and certificate expiration timelines that don't make a distinction between firewalled OT networks and Internet-facing webservers don't allow anything to run for a decade without major, risky rewrites that cost tens of thousands of dollars for highly specialized engineering services and minimal downtime. Sure, adding a cert to the SCADA server is trivial, it runs Windows Server and has a NIC that can access the Internet, but on the other NIC...there's a menagerie of 30 years of industrial oddities.
If your homelab is still working after 2 years, that's great, but if it's not running after 100 years would you call that an organizational failure?
