Protection of Critical Infrastructure

The protection of critical infrastructure is one of CISA’s top priorities. This includes sectors such as energy, transportation, healthcare, and communication systems. CISA works closely with these sectors to identify potential vulnerabilities and develop risk management strategies to mitigate the impact of cyber attacks.

To achieve this, CISA works collaboratively with federal agencies, state and local governments, and private sector partners. It also conducts risk assessments and provides recommendations for improving security in critical infrastructure systems. By leveraging its expertise and resources, CISA helps to build a more secure and resilient infrastructure that can withstand cyber attacks.

Incident Response and Recovery

In addition to proactive measures, CISA is also responsible for responding to cyber incidents. In the event of a significant cyber attack or breach, CISA works with its partners to provide technical assistance and coordinate response efforts. It also offers guidance on how to mitigate the effects of an attack and recover from any damages incurred.

CISA’s National Cybersecurity and Communications Integration Center (NCCIC) serves as a central hub for coordinating incident response and sharing information with government and private sector partners. This rapid response capability is crucial for minimizing disruptions and restoring systems affected by a cyber attack.

Strategies and Initiatives Implemented by CISA

CISA has rolled out several initiatives and strategies to fulfill its mission of safeguarding the nation’s cybersecurity and critical infrastructure. These include:

National Cybersecurity Awareness Month

Every October, CISA leads the national effort to raise awareness about the importance of cybersecurity. Through this annual campaign, CISA strives to educate the public and encourage everyone to take steps to secure their online activities. This includes promoting safe online practices, such as using strong passwords, enabling multi-factor authentication, and keeping devices and software up to date.

Critical Infrastructure Cyber Community Voluntary Program

The voluntary program aims to improve the security and resilience of critical infrastructure by providing participants with customized risk management support. Participants work closely with CISA to identify risks, implement best practices, and develop response plans tailored to their specific needs.
