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: TMPRIESTLEY

Instructor comments: The instructor was very well versed on the topic and knew how to apply it to real-life examples. He led the labs and was very excited about the topic which kept the interest of myself and other class members. Sometimes his volume level was a little high- however the room the class was in was very small. Too small for a big personality!

Facilities comments: I was unaware of the facility changes, but that was at no fault of anyone since I was a drop-in for the course. They were very helpful and quick to mediate the issue.

TN-813: Certified in Governance, Risk and Compliance (CGRC)

Course Overview:

TN-813: Certified in Governance, Risk, and Compliance (CGRC) course is for the (ISC)²® Certified in Governance, Risk, and Compliance (CGRC) credential previously known as Certified Authorization Professional (CAP). This course walks the student through the Risk Management Framework following practices the NIST pubs. CGRC is an objective measure of the knowledge, skills and abilities required for personnel involved in the process of certifying and accrediting security of information systems. Specifically, this credential applies to those responsible for formalizing processes used to assess risk and establish security requirements. Their decisions will ensure that information systems possess security commensurate with the level of exposure to potential risk, as well as damage to assets or individuals.The CGRC credential is appropriate for civilian, state and local governments in the U.S., as well as commercial markets. CGRC certification applies to job functions such as authorization officials, system owners, information owners, information system security officers, and certifiers. CGRC is crucial to the Management staff.

This course is the “why” of the entire security field. It provides a logical way of allocating resources where there is greatest risk and why we make the decisions we make in the field of security. It is TechNow’s view that of all the security courses we have seen, this course genuinely puts the “big picture” of security in front of the students. Students actually come to an understanding of truly what is critical to security of an enterprise versus a bunch of nuts and bolts of security.

TechNow’s CGRC course covers all of the (ISC)²® CGRC 7 Knowledge domains:

Security and Privacy Governance, Risk Management, and Compliance Program
Scope of the System
Selection and Approval of Framework, Security, and Privacy Controls
Implementation of Security and Privacy Controls
Assessment/ Audit of Security and Privacy Controls
System Compliance
Compliance Maintenance

RMF Related Steps
