The US Cybersecurity and Infrastructure Safety Company (CISA) lately introduced the 2024 cybersecurity priorities for the Joint Cyber Protection Collaborative (JCDC). The six priorities are grouped into three focus areas designed to harmonize cybersecurity targets and efforts throughout authorities and business partnerships for important infrastructure safety. At first look, it could appear that these priorities lack correlation to your day-to-day operational actions. Listed below are sensible cybersecurity suggestions to align your operational know-how (OT) cybersecurity technique to the JCDC priorities that can enhance your cybersecurity resiliency.
Focus 1: Defend Towards Superior Persistent Menace (APT) Operations
Precedence 1: Uncover and defend in opposition to malicious abuse by APT actors, significantly these backed by the Folks’s Republic of China, on and in opposition to US-based infrastructure.
Advice: Leverage exterior menace intelligence service suppliers centered on important infrastructure industries and nation-state menace actors. These options ship indicators of compromise that may be ingested into cybersecurity applied sciences similar to firewalls and safety occasion and knowledge administration, bettering the safety in opposition to and detection of cyberthreats. In addition they present the ways, methods, and procedures utilized by menace actors bettering vulnerability prioritization, menace searching, and incident response capabilities. Having the proper intelligence facilitates higher decision-making and lets you enhance menace detection and response.
Precedence 2: Put together for main cyber incidents.
Advice: It’s mentioned that follow makes excellent. Don’t try for perfection, however follow your incident response procedures sufficient to change into proficient. A significant cyber assault in opposition to important infrastructure operations can have catastrophic bodily penalties to the surroundings, human security, and availability of public providers. Responding to a cyber incident in OT environments requires a special strategy. An efficient response entails seamless coordination between cyber, bodily, and operations groups that may solely change into a actuality when you follow incident response often. Conduct an annual train at a minimal, however a quarterly cadence is good.
Focus 2: Elevate The Cybersecurity Baseline
Precedence 3: Assist state and native election officers safe their networks and infrastructure in opposition to cyber threats as a part of the CISA’s broader election safety efforts.
Advice: Even if you’re circuitously concerned within the election infrastructure and mechanics, your group nonetheless has a job in guaranteeing a good and secure election course of. Concentrate on narrative assaults that use misinformation and disinformation in affiliation together with your firm to control perceptions. Replace your menace intelligence program to watch open and darkish net sources for these kinds of assaults. Construct into your incident response plan processes to shortly decide the accuracy of the data, and talk the reality to reduce the influence to your model and restore confidence within the election course of.
Precedence 4: Measurably lower the influence of ransomware on important infrastructure.
Advice: Ransomware surged in 2023 and exhibits no indicators of slowing down. There isn’t a fast repair to the ransomware menace, so organizations ought to give attention to cybersecurity fundamentals, together with investing in applied sciences designed for OT that handle use instances similar to asset discovery and identification. In parallel, deploy menace and anomaly detection instruments whilst you construct out the remainder of your cybersecurity technique. You must plan for a mixture of passive and lively scanning OT safety options to extend protection whereas minimizing disruptions.
Precedence 5: Make measurable progress towards a world the place know-how is safe by design.
Advice: It might be straightforward to place the highlight on builders and unique gear producers (OEMs), however patrons bear duty, as properly. Consumers should put stress on OEMs by requiring stronger cybersecurity options similar to sturdy entry management, as an alternative of ready for laws to drive change, and be keen to pay for it. Industrial automation units have lengthy lives in OT environments, so this modification should begin right this moment.
Focus 3: Anticipate Rising Expertise And Dangers
Precedence 6: Lower the danger posed by synthetic intelligence to important infrastructure.
Advice: Don’t fear about AI in OT environments proper now and focus as an alternative on securing cloud deployments. Cloud options is probably not thought of an rising know-how, however adoption is rising in OT environments and poses a major threat to important infrastructure operations. This requires implementing a sturdy cloud governance regime, requiring obligatory safety instrumentation, and tooling into all cloud workloads. Embed safety into cloud deployments from the begin to notice the benefits that cloud has to supply whereas minimizing dangers.
