Transportation Security Administration (TSA) Rail Cyber Compliance is a framework designed to ensure the security of the nation’s rail systems from cyber threats. Its primary function is to safeguard rail infrastructures and ensure the continuity of rail services. This is achieved through the enforcement of a set of cybersecurity practices.

Pipeline Cyber Asset Classification involves identifying and categorizing assets that are essential to the rail network’s operation and are susceptible to cyber threats. It’s a critical step in securing the cyber infrastructure of the rail system, understanding its vulnerabilities, and directing protective resources efficiently.

The Corporate Security Plan outlines the organization’s approach to cybersecurity. It includes strategies to protect data, infrastructure, and operations from potential cyber threats, which are critical in ensuring a consistent response to such threats across the organization.

Physical Security refers to measures taken to protect the physical equipment and infrastructure, like servers and network devices, which could be targeted in a cyberattack. These measures may include controlling access to sensitive areas, intrusion detection systems, and surveillance cameras.

Multi-Factor Authentication is a security measure requiring more than one method of authentication from independent categories of credentials to verify the user’s identity for a login or other transaction. This reduces the risk of successful cyber attacks and unauthorized access.

Network Segmentation is a security practice where parts of the network are divided into separate sections to enhance performance and security. This can limit the scope of a potential breach to only a segment of the network, making it harder for an attacker to gain full system access.

Logging, Alerting, and Retention practices involve recording and monitoring system activities to detect any anomalies or potential cyber threats. Keeping a comprehensive log of activities assists in identifying the source, nature, and timeline of any cyber attacks.

Traffic Filtering and Monitoring involves examining network traffic to detect and block any malicious activities. It ensures the security and integrity of data flowing across the network.

Domain Name System Capabilities refers to the ability to secure and manage the system that translates domain names to IP addresses. It includes protecting the system from DNS attacks and ensuring the accuracy and integrity of the DNS data.

Patch Mitigation and Vulnerability Management involves identifying, classifying, and addressing vulnerabilities in the systems and applying patches as necessary. Timely patching and effective vulnerability management can significantly reduce the risk of cyber attacks.

Cyber Security Controls, Access Control, and Privileged Rights Access deals with implementing measures that ensure only authorized individuals have access to critical systems and data. This includes managing user privileges, implementing strong access controls, and routinely reviewing access rights.

Incident Response & Testing involves the establishment of processes and procedures to respond swiftly and effectively to cyber incidents. Regular testing ensures these measures work as expected in the event of an actual incident.

Finally, a Third-party evaluation of the Owner/Operator’s Operational Technology Design and Architecture ensures an independent, unbiased review of the design and implementation of cyber security measures. This provides an additional level of assurance that the systems are robust, secure, and resilient against potential cyber threats.
