Cybersecurity
Understanding Our Systems
Assessing and Deterring Threats
Our adversaries are devising new ways to disrupt or destroy critical infrastructure and may do so in the event of a major conflict or crisis. At these times, they may seek to hinder U.S. military mobilization, sow chaos, and harm the American people. Our national security capabilities rely on assured access to critical infrastructure, such as energy, communications, transportation and water systems.
Lawrence Livermore National Laboratory has developed a portfolio of capabilities that enable cyber defenders to understand the asset inventory, which includes networks, hardware components and software, as well as how an adversary might successfully attack the system.

Program Highlights
Quantitative Intelligent Adversary Risk Analysis (QIARA)
The QIARA framework is a comparative risk assessment approach focused on cyber and physical attacks. LLNL leverages QIARA and its related tools to develop realistic infrastructure disruption scenarios, provide quantitative score and enabling prioritization and offer options for mitigation.
Peregrine
The Peregrine suite of assessment tools is underpinned by physics-based models and takes a mathematical optimization approach to identify nodes an adversary may attack to achieve maximum disruptive impact.
Python Simulator for Cyber Event Scenarios (PySCES)
PyCES is a modeling and simulation tool designed to help analysts rapidly estimate high-level potential impacts of a cyber vulnerability in industrial control system equipment. The tool traces consequences as a vulnerability impacts devices, devices impact facilities and facilities impact infrastructure systems.
