Continuous Diagnostics and Mitigation (CDM) Training

These trainings provide instructor-led, hands-on CDM Dashboard training for Federal Civilian Executive Branch (FCEB) employees and contractors in a cyber virtual learning environment (CVLE). The virtual and in-person training events enhance the dynamic CDM approach to fortifying the cybersecurity of government networks and systems. These courses are designed for personnel at agencies participating in the CDM program who monitor, manage, or oversee controls on their information systems such as ISSOs, CDM POCs, ISSMs and those reporting metrics.

These CDM trainings enable participating FCEB agencies to improve their networks and defend against cyber adversaries. The CDM training provides detailed class discussion with real world simulated computer labs using a CVLE. The training will teach participants the basics of CDM and how to use the CDM Dashboard capabilities to help mitigate agency threats. We will also offer various CDM resources and external references.

Currently, the courses use version ES 6.6 of the CDM Dashboard within the CVLE. The current content focuses on the most recent version of the dashboard, including FISMA Automation, HVA reporting, CyHy (Cyber Hygiene) and SCuBA (Secure Cloud Business Applications), and other dashboard capabilities. Current CDM courses are offered at the 100-level (Introductory) and 200-level (Intermediate).

Eligible Audience: Open to federal employees and supporting contractors.

Industrial Control Systems (ICS) Training 

This no-cost ICS cybersecurity training is designed for critical infrastructure owners and operators. Its primary goal is to help reduce cybersecurity risks across critical infrastructure sectors while strengthening collaboration between CISA and the private sector.

Participants register through the CISA Virtual Learning Portal (VLP), where online courses become available immediately upon enrollment. Online course durations range from 2 to 20 hours. In-person training is delivered by the Idaho National Laboratory (INL) in Idaho Falls, Idaho, and typically runs Monday through Thursday of the scheduled program week.

*The ICS300 online course is a prerequisite for attending the in-person ICS301 training hosted by CISA at the Idaho National Laboratory. This ICS300 course focuses on many of the hands-on skills needed to protect and secure Industrial Control Systems and Operational Technology networks. The ICS401 course is available either online (ICS401V) or in-person (ICS401L).

Eligible Audience: Primary audience is critical infrastructure partners, however, federal, state, local, tribal, and territorial government employees with critical infrastructure responsibilities are also eligible.

Skilling Continuation Labs (SCLs)

CISA is now offering Skilling Continuation Labs (SCLs), which are part of CISA’s ongoing goal to better equip the cyber workforce with the skills needed to defend our country against cyber threats. This new series of hands-on training opportunities cover specific cyber topics and use cases that are tied to CISA guidance and publications (All Resources & Tools | CISA). These labs are standalone training sessions and are not part of a curriculum, allowing the learner to focus solely on the topic of interest, minimizing training time as the labs strengthen the role of the cyber workforce!  

The SCLs cover:

• Network Segmentation – associated with CISA’s Securing Network Infrastructure Devices guidance, this topic is crucial to defending cyber threats as these devices are ideal targets for malicious cyber actors
• Enhanced Security with DNS – leveraging CISA’s Encrypted Domain Name System (DNS) Implementation Guidance and the Protective Domain Name System Resolver, this topic is part of the vital effort to advance and strengthen zero trust cybersecurity across agencies
• Living Off the Land Attacks – using CISA’s techniques, in cooperation with the National Security Agency (NSA) and the Federal Bureau of Investigation (FBI), this lab provides threat detection information and mitigations applicable to LOTL activities, regardless of threat actor covering malware attacks and how effective logging can detect them. 
• Automated Defenses – using CISA’s best practices for denial-of-service attacks, this lab covers the concept of automated defenses, demonstrating endpoint detection and response (EDR). It shows how to mitigate denial of service attacks using firewall throttling techniques and the use of honeypots. 
• XZ Utils – A Case Study on Supply Chain Trust – applying CISA’s XZ Utils Vulnerability prevention method, this lab applies supply chain trust, using SBOMs to manage vulnerabilities in open source software. A “software bill of materials” (SBOM) has emerged as a key building block in software security and software supply chain risk management. This lab guides the learner through an XZ Utils supply chain trust scenario.
• Secure Programming – using the CISA Secure by Design approach, this lab examines any flaws in code that could lead to overflow attacks and details how to prevent them from occurring. The lab focuses on SQL and OS command injection vulnerable and exploitable code.

These Skilling Continuation Labs were created for cyber professionals with some IT/cyber experience who fall into the upper beginner to lower intermediate cyber skill range. These labs are available to play in the President’s Cup Practice Area. We are confident these labs will provide a continuation of skills for the cyber professional.

Eligible Audience: Open to federal employees and military only.
