After the chief order to bolster the nations cybersecurity following the Colonial Pipeline assault, the U.S. Transportation Safety Administration (TSA) has been releasing new mandates for essential infrastructure reminiscent of freight and passenger rail, pipelines, and airports, with extra industries to observe.

The networks that assist these essential infrastructures are mission-critical, which signifies that it’s important to have the ability to keep linked whereas securely administering coverage within the industrial house. Being an trade chief in networking and safety throughout each the knowledge know-how (IT) and operational know-how (OT) domains, Cisco is in a singular place to ship an end-to-end safety technique, whereas enhancing operational uptime and resiliency.

To strengthen the cybersecurity posture of the nation’s essential infrastructure, there are 4 key necessities outlined by the mandates, highlighted in daring textual content under.

Community segmentation

The primary requirement is to “Implement community segmentation insurance policies and controls to make sure that the Operational Know-how (OT) system can proceed to securely function if an Data Know-how (IT) system has been compromised.”

Utilizing a defense-in-depth strategy, Cisco addresses this requirement in lots of components of the community, adapting to the distinctive structure wants of particular person organizations. The answer is a standard one, use the community infrastructure to phase a community. Don’t wait till you attain a “safety equipment” to do safety. Cisco gives an end-to-end segmentation answer by which information is saved inside its personal digital community from supply to vacation spot, wherever which may be.

To assist the distinctive necessities of business networks, the attain of Cisco SD-WAN has been expanded by way of Cisco Industrial Routers, which give the connectivity, mobility, and safety required for essential infrastructure. SD-WAN segments visitors on the fringe of the community and maintains separation by way of all related factors within the community. Coverage may be orchestrated throughout a number of enforcement factors within the community utilizing Cisco Catalyst SD-WAN, or—in case your group prefers—can assist the evolution to a safe service edge (SSE) with Cisco Safe Entry.

Entry management

TSA highlights the necessity to “Implement entry management measures to safe and forestall unauthorized entry to Crucial Cyber Programs.” As OT units traverse each the LAN and the WAN with a unified id, Cisco can implement coverage in every single place. Cisco Safety Group Tags (SGTs) establish the position {that a} system has on the community, and the related privileges are enforced by switches, routers, and firewalls, relying on the place the information flows.

Distant customers, whether or not inner technicians or vendor assist, typically want entry to essential cyber programs. Cisco Safe Tools Entry (SEA) gives versatile entry for distant configuration and upkeep of business property in distributed areas whereas minimizing safety danger.

Steady monitoring

Segmentation is just not sufficient to finish a safety answer. By implementing “steady monitoring and detection insurance policies and procedures to detect cybersecurity threats and proper anomalies that have an effect on Crucial Cyber System operations,” we are able to frequently monitor and consider the belief of each customers and units on our networks and push coverage again into the community as safety posture modifications.

To offer visibility and safety posture to the commercial community, Cisco Cyber Imaginative and prescient is embedded in Cisco networking infrastructure with a purpose to keep away from the necessity for devoted home equipment and/or pricey Switched Port Analyzer (SPAN) options. Cyber Imaginative and prescient identifies property, their traits, and their communication patterns to “scale back the chance of exploitation of unpatched programs by way of the appliance of safety patches and updates for working programs, purposes, drivers and firmware on Crucial Cyber Programs in a well timed method utilizing a risk-based methodology.” Cyber Imaginative and prescient mechanically identifies system vulnerabilities and calculates danger scores so you’ll be able to proactively construct an enchancment course of to deal with dangers.

Cisco’s capabilities, highlighted above, not solely meet the present TSA Cybersecurity Directive necessities but additionally allow purchasers to ship extra sturdy cybersecurity capabilities to thwart efforts by trade threats. Most importantly, these capabilities are foundational for enabling each safety and operational resiliency in addition to optimizing the efficiency of mission-critical networks.
