How to Comply with TSA NA-21-05: A Comprehensive Guide on Cybersecurity Incident Reporting

The Transportation Security Administration (TSA) is responsible for protecting the nation’s transportation systems, including airports, highways, railways, and pipelines. Given the rise of cyber threats in recent years, TSA has released guidelines and requirements for reporting cybersecurity incidents in the transportation sector. This article provides a comprehensive guide on how to comply with TSA NA-21-05, which outlines the reporting requirements and best practices for responding to cybersecurity incidents.

What is TSA NA-21-05?

TSA NA-21-05 is a directive released by the Transportation Security Administration that provides guidance and requirements for reporting cybersecurity incidents in the transportation sector. This directive applies to all transportation modes, including air, land, and sea. The goal of the directive is to facilitate the timely and accurate reporting of cybersecurity incidents to the appropriate authorities, which can help prevent and mitigate future incidents.

Reporting Requirements

Under TSA NA-21-05, transportation entities are required to report cybersecurity incidents to the National Cybersecurity and Communications Integration Center (NCCIC) within 72 hours of discovery. The report must include basic information about the incident, including the date and time of occurrence, the type of incident, the affected systems or assets, and the known or suspected impact of the incident. In addition, entities must update the NCCIC on any material changes to the incident as they occur.

Best Practices for Responding to Cybersecurity Incidents

In addition to reporting requirements, TSA NA-21-05 provides guidance on best practices for responding to cybersecurity incidents. These include:

– Identifying and containing the incident: The first step in responding to a cybersecurity incident is to identify and contain it as quickly as possible. This may involve disconnecting affected systems from the network, disabling affected accounts, or taking other measures to limit the impact of the incident.

– Assessing the impact: Once the incident has been contained, it’s important to assess the impact of the incident on the organization’s operations and assets. This can help decision-makers determine the appropriate response and prioritize recovery efforts.

– Notifying stakeholders: It’s important to notify relevant stakeholders about the incident, including internal staff, external partners, customers, and regulatory authorities. This can help minimize the potential impact of the incident and reduce the risk of future incidents.

– Conducting a post-incident analysis: After the incident has been resolved, it’s important to conduct a post-incident analysis to identify lessons learned and areas for improvement. This can help organizations better prepare for future incidents and improve their overall cybersecurity posture.

Examples of Cybersecurity Incidents in the Transportation Sector

There have been several high-profile cybersecurity incidents in the transportation sector in recent years. These include:

– Targeted attacks on airports and airlines, which have resulted in stolen data, disrupted operations, and financial losses.

– Ransomware attacks on shipping companies, which have resulted in delayed deliveries and increased costs.

– Cyber attacks on autonomous vehicles, which have raised concerns about the safety and security of these systems.

In each of these cases, early detection and timely reporting of the incident could have helped prevent or mitigate the impact of the incident.

Conclusion

The rise of cyber threats in the transportation sector highlights the importance of effective incident reporting and response. TSA NA-21-05 provides a comprehensive framework for complying with reporting requirements and best practices for responding to cybersecurity incidents. By following these guidelines, transportation entities can help protect their operations, assets, and customers from the potential impact of cyber attacks.
