TN-575: Open Source Network Security Monitoring

Course Overview:

TN-575: Open Source Network Security Monitoring teaches students how to deploy, build, and run an NSM operation using open source software and vendor-neutral tools. No network is bullet proof and when attackers access your network, this course will show you how to build a security net to detect, contain, and control the attacker. Sensitive data can be monitored and deep packet and deep attachment analysis can be achieved. As organizations stand up a Security Operations Center (SOC) the enterprise NSM is the key ingredient to that SOC. This course not only teaches how to implement an NSM technologically, but how to effectively monitor an enterprise operationally. You will learn how to architect an NSM solution: where to deploy your NSM platforms and how to size them, stand-alone or distributed, and integration into packet analysis, interpret evidence, and integrate threat intelligence from external sources to identify sophisticated attackers. A properly implemented NSM is integral to incident response and provides the responders timely information to react to the incident. TN-575: Open Source Network Security Monitoring is a lab intensive environment with a cyber range that gives each student in-depth knowledge and practical experience monitoring live systems to include: Cisco, Windows, Linux, IoT, and Firewalls.

Attendees to TN-575: Open Source Network Security Monitoring class will receive TechNow approved course materials and expert instruction.

This Course is taught utilizing Security Onion or RockNSM as specified by the customer.

User: sjsmith2262

Instructor comments: without question, Dave Askey knows his material!!! great instructor that gave a personalized approach.

Facilities comments: class was taught in a hotel reception area, very nice, quiet and convenient for all people

User: synistry

Instructor comments: Dave was great! (as always). Wealth of knowledge and a master at customizing course content to match the education level of his students. The class kept entirely in pace with where we were at as a group overall on a day to day basis.

Facilities comments: Facilities were overall really nice. The only complaint is that the hotel / conference center had us move rooms on one occasion, and kicked us out early on two others. I would assume this is due to the last minute location change, so I don't think there is anything anyone could have done better in the situation.

TN-911: Cyber Threat Intelligence (CTI) Analysis and 800-172 Seminar

Course Overview:

TechNow’s TN-911: Cyber Threat Intelligence (CTI) Analysis and 800-172 Updates Seminar, is a one day seminar that covers the objectives of TechNow’s TN-905: Cyber Threat Intelligence Analysis five day course in a one day seminar format plus some other security enhancements of 800-172. Upon request, this seminar can be presented in multi-day format based upon the depth of knowledge required. The NIST PUB 800-172 security enhancement update to 800-171 regarding 03.11.1 Risk Assessment, introduces the security enhancements of a Threat Awareness Program, Threat Hunting, and Predictive Cyber Analytics. TN-911 distills the TN-905 CTI five day course and aligns it to assessing compliance with 800-172. For the seminar, selected course labs are converted to demos, and the important points and outcomes of topics are presented. The TN-911 CTI Seminar discusses the applicability of the 800-172 security enhancements to the organization being assessed, and how to think about the the appropriate strength of the controls related to the organizations criticality of the information and the risk involved for contracted work with the DoD.

TechNow’s TN-911: Cyber Threat Intelligence Analysis Seminar addresses significant changes that have been made to SP 800-172 in transitioning to Revision 3, regarding new enhanced security requirements based on (1) the latest threat intelligence and (2) empirical data from cyber-attacks. With the intent of addressing CUI that may be associated with a critical program or a high value asset.

Those programs and assets are potential targets for advanced persistent threat (APT). Cyber Threat Intelligence supports the required functions of NIST 800-172 of Penetration Resistant Architecture (PRA), Damage Limiting Operations (DLO) and Cyber Resiliency (CRS).

Regarding 800-172 This seminar includes:

3.2.1E Awareness Training (rev 3 – Advanced Literacy and Awareness Training)
3.11.6E Supply Chain Risk Management SCRM (rev 3 withdrawn, moved to other controls)
3.11.7E SCRM Planning (rev 3 withdrawn, moved to other controls)
3.12.1E Penetration Testing
800-172, 3.11 Risk Assessment
- 03.11.01E Threat Awareness Program

03.11.03E Predictive Cyber Analytics

Introduction leveraging data, machine learning, and real-time analysis with automation to anticipate threats before they occur.

How to assess an environment to validate:
- Data aggregation from network logs, user activities, system logs, and external threat intelligence feeds into a centralized platform like a SIEM
Use of machine learning algorithms to identify patterns, uncover correlations, and spot anomalies in real-time
Integration with incident response workflows
Staff skill competency level and integration into Predictive Cyber Analytics to mitigate advanced adversarial techniques against machine learning such as:
- Attacks of Evasion, Poisoning, and Model Tampering
- Utilization of exercises or Red Teaming to validate practices and effectiveness of Predictive Cyber Analytics.
