Design & Implementation of OEM ICS Cybersecurity Frameworks: The Good, The Bad, and The Ugly
The cyber threat landscape today continues to pose a myriad of unique challenges. This is especially the case for industrial organizations due to factors such as aging equipment, poor design or implementation, skills gaps and a lack of visibility. These shortcomings are exacerbated by the mean time to breach detection, which continues to hover above 150 days on average.
The SANS Institute via the Center for Internet Security recommends the Critical Security Controls as a means for organizations to strengthen their digital security. These measures make it clear that once an organization has completed a hardware and software inventory, one of the most important security controls they can implement is secure configurations.
One of the four actions to implement, automate and measure effectiveness is as follows:
Improved information security configuration and hygiene to reduce the number and magnitude of security vulnerabilities and improve the operations of networked computer systems, with a focus on protecting against poor security practices by system administrators and end-users that could give an attacker an advantage.
A Needle in the Haystack Conundrum
Unfortunately, implementing the CIS Critical Security Controls is no small undertaking. At first glance, Basic Control 5 “Secure Configuration for Hardware and Software on Mobile Devices, Laptops, Workstations and Servers” and Foundational Control 11 “Secure Configuration for Network Devices, such as Firewalls, Routers and Switches” appear to be trivial. In reality, implementing these two measures constitutes a significant task. I liken security configuration management to finding a needle in a haystack; an organization only has to make a single mistake to allow an adversary to wreak havoc. I’m reminded of the Capital One attack in 2019 that was accomplished through leveraging what was described as a “configuration vulnerability.” An organization of any size, not just a major financial institution like Capital One, can (Read more...)
