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.

TN-913: Cloud Security Fundamentals

Course Overview:

TechNow Cloud Security Fundamentals addresses the loss of hands-on control of system, application, and data security in the Cloud computing environment. Security teams wrestle with the impact and liability of Cloud computing on an organization. This course enables the security team to assist in contract language and Service Level Agreements (SLAs) when utilizing Cloud Service Providers (CSPs).

Compliance and auditing are introduced with strategies for control verification and audit analysis in the CSP environment. Software as a Service (SaaS) to Infrastructure as a Service (IaaS) and everything in between require a compliance strategy. Students will go in-depth into the architecture and infrastructure fundamentals for private, public, and hybrid clouds. Topics covered include: patch and configuration management, virtualization security, application security, and change management. Policy, risk assessment, and governance within cloud environments will be covered with recommendations for both internal policies and contract provisions to consider.

TechNow has worked worldwide enterprise infrastructures for over 20 years and has developed demos and labs to exemplify the techniques required to effectively manage security in the cloud environment.

Attendees to TN-913: Cloud Security Fundamentals will receive TechNow approved course materials and expert instruction.
