All varieties of Netwars are PCTE compatible.

Persistent Cyber Training Environment (PCTE) is a training platform that supports Joint Cyberspace Operations Forces by providing individual sustainment training, team certification, mission rehearsal, and the foundation for collective training exercises. It leverages existing connectivity to facilitate the sharing of resources, and provides additional cyber “maneuver space.” PCTE enables realistic training with variable conditions to increase readiness and lethality of our Cyberspace Operations Forces, while standardizing, simplifying, and automating the training management process.

PCTE supports the United States Cyber Command (USCYBERCOM) by enabling a critical need for the DoD and Joint Cyberspace Operations Forces to train at the individual, team, and force level. PCTE is one of the five elements of the Joint Cyber Warfighting Architecture (JCWA), provides a comprehensive, integrated cyberspace architecture to achieve and sustain the insight, agility, and lethality necessary for maintaining a competitive advantage against near-peer adversaries. PCTE will integrate and be inter-operable with the other JCWA elements to enable teams to train and rehearse using the available JCWA operational tools and capabilities.

CyberCity is a hands-on, kinetic cyber range for learning how to analyze, assess, and defend control systems and operational infrastructure, as well as how to identify vulnerabilities that could result in significant kinetic impacts. It also guides students on strategies for conveying findings to leadership and public planners on the potential kinetic impacts of vulnerabilities and cyber attacks.

CyberCity is a 1:87 scale miniaturized physical city controlled by the same equipment found in cities and municipalities around the globe, featuring SCADA-controlled electrical power distribution, as well as water, transit, hospital, bank, retail, and residential infrastructures. CyberCity challenges participants to defend the city’s infrastructure from terrorist cyber attacks, and to use offensive tactics to retake or maintain control of critical assets.

The Cyber Situational Training eXercise (Cyber STX) is SANS’s premiere in-depth training and validation cyber range. Teams of participants engage in an active Red-on-Blue team battle. Cyber STX provides a week of intense attack and defense of the critical cyber terrain. The red team develops and deploys a comprehensive campaign based on one or more specific advanced persistent threat(s) (APTS), utilizing their same tactics, techniques, and procedures (TTPs) and Indicators of Compromise (IOCs) as the given APTs. The blue team is challenged to defend against the red team attack.

SANS instructors and teaching assistants (TAs) play the part of blue team coaches and red team/OPFOR operators, creating a highly realistic environment that can measure the capabilities of a blue team and its tools and communications, as well as the effectiveness of their TTPs. Additionally, the Cyber STX can take red teamer skills to the next level. SANS offers the Cyber STX on-site for private events, virtually in a cloud-based environment, or in a mixed mode with participants both local and remote. Cyber STX can include both Information Technology (IT) and Operations Technology (OT) infrastructures, depending on the specific environments participants are called on to protect. From an OT perspective, SANS runs Cyber STX missions with Industrial Control System (ICS) devices for power distribution, power generation, water refinement, port crane operations, manufacturing systems, and more.

Professionals who should consider taking Cyber STX include experienced Military groups seeking in-depth training and validation, cyber protection teams, government agencies with responsibilities for defending critical systems, and large private industry organizations protecting complex infrastructure.

In most cases, SANS is able to craft a custom range challenge to meet the needs of the customer. Custom range requests require a customer meeting with the Cyber Range team to scope the project and provide options. Additionally, during the meeting SANS will help define learning objectives, develop scorecards, and configure the content and platform.
