Malware, viruses and worms are only a few of the cybersecurity threats that affect your online security, privacy and personal information. Learn what the U.S. Cybersecurity Emergency Response Team (US-CERT) is and how it helps protect systems every day.
History of the U.S. Cybersecurity Emergency Response Team
The US-CERT began in the early 2000s after the federal government documented an increase in cyber breaches and sought a coordinated response. Congress initially created the Federal Computer Incident Response Center (FedCIRC) to address those risks.
Responsibilities moved to the Department of Homeland Security a few years later, and FedCIRC was renamed US-CERT as its mission broadened. The organization began coordinating information sharing, developing defensive measures, and supporting boundary protection for federal systems.
Over time, US-CERT developed into an authoritative security partner for federal and international organizations. Private industries also use US-CERT resources to help improve resilience; businesses interested in planning for cyber incidents can explore options such as Crisis Response Insurance.
What Does the U.S. Cybersecurity Emergency Response Team Do?
The U.S. Cybersecurity Emergency Response Team performs several critical mission activities for government and private stakeholders.
- Analyze data about emerging cyber threats.
- Collaborate with foreign governments and international entities to improve overall cybersecurity posture.
- Detect intruders and help prevent attacks against civilian executive branch systems.
- Develop actionable guidance, tips and mitigation information for federal departments, critical infrastructure owners and private industry partners.
- Respond to and coordinate responses to emerging cyber threats and incidents.
How Does US-CERT Handle Potential Threats?
When US-CERT receives a threat report from any source, including the public, it quickly assesses the report, determines its credibility, and takes steps to mitigate the risk.
The team works with a broad set of partners — federal agencies, international organizations, research communities and private sector entities — to protect infrastructure, systems and assets that are critical to national and economic security.
Find Out About US-CERT Threats
Stay updated on active and emerging cybersecurity issues through several US-CERT resources that summarize vulnerabilities, alerts and recommended actions.
- Weekly Vulnerability Bulletins — summaries of new vulnerabilities and available patch information.
- Technical Alerts — information about incidents, vulnerabilities and trends that pose significant risk and recommended mitigation steps.
- Current Activity entries — concise descriptions of issues and associated actions to help consumers and organizations remain safe.
- Tips — practical details about issues US-CERT’s constituents may find valuable or helpful.
- NVD — standards-based vulnerability data managed for public use.
In a nutshell, US-CERT helps keep individuals, businesses and the country safer from computer attacks that can threaten national security and personal information. Organizations that operate industrial facilities may also evaluate coverage options like Foundry Insurance when planning incident response and recovery, and if you want to review policy options, consider talk to an agent.
