TSA issues new cybersecurity measures to better defend airlines

By Security Staff

March 8, 2023

TSA has issued a new cybersecurity amendment. A similar announcement was made in October of 2022 for passenger and freight railroad carriers. This is part of the Department of Homeland Security’s efforts to increase the cybersecurity resilience of U.S. critical infrastructure and follows extensive collaboration with aviation partners. 

TSA is taking the emergency action because of persistent cybersecurity threats against U.S. critical infrastructure, including the aviation sector. The new emergency amendment requires that impacted TSA-regulated entities develop an approved implementation plan that describes measures they are taking to improve their cybersecurity resilience and prevent disruption and degradation to their infrastructure. They must also proactively assess the effectiveness of these measures, which include the following actions:

Develop network segmentation policies and controls to ensure that operational technology systems can continue to safely operate in the event that an information technology system has been compromised, and vice versa.

Create access control measures to secure and prevent unauthorized access to critical cyber systems.

Implement continuous monitoring and detection policies and procedures to defend against, detect and respond to cybersecurity threats and anomalies that affect critical cyber system operations.

Reduce the risk of exploitation of unpatched systems through the application of security patches and updates for operating systems, applications, drivers and firmware on critical cyber systems in a timely manner using a risk-based methodology.

Previous requirements for TSA-regulated airport and aircraft operators included measures such as reporting significant cybersecurity incidents to the Cybersecurity and Infrastructure Security Agency (CISA), establishing a cybersecurity point of contact, developing and adopting a cybersecurity incident response plan and completing a cybersecurity vulnerability assessment.
