Section 4: Incident Response

Anchor: #i1354191

Introduction

This section establishes how TxDOT maintains an Incident Response Plan in order to properly respond to, document, and track incidents. The Incident Response Plan provides a high-level approach for TxDOT’s response when information security policies are breached. It provides an emergency-based method to address the “Response” objective of the Texas CyberSecurity Framework.

CAUTION: Documents related to incident response are confidential. The incident response plan needs will be distributed to department heads and other stake holders on a need-to-know basis.

Protocol

An incident response plan must describe a strategic response to a breach of routine business practices and provide sufficient details to continue business functions. The plan is tested annually and is updated as needed. TxDOT’s response includes assembling a trained incident response team.

All incidents are reported to TxDOT’s Information Security Officer (ISO) as soon as they are discovered. The ISO notifies stakeholders according to the escalation levels established in the incident response plan. TxDOT implements an automated incident handling response to include the preparation, detection and analysis, containment, eradication, and recovery from incidents.

WARNING: Information about security incidents will be on a "need-to-know" basis and are confidential in nature. Reports are reviewed and approved by the Information Security Officer (ISO) prior to release to outside agencies.
