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.

Course Overview:

CT-395: CompTIA CySA+ Cybersecurity Analyst is for IT professionals looking to gain IT security analyst skills, and for those following the recommended skills pathway to achieve cybersecurity mastery. It provides a bridge between CompTIA Security+ (CT-325) and CompTIA Advanced Security Practitioner (CASP,CT-425), thus completing a certification path within the CompTIA family of certifications. As attackers have learned to evade traditional signature-based solutions, an analytics-based approach has become extremely important. CySA+ applies behavioral analytics to the IT security market to improve the overall state of security. The CompTIA Cybersecurity Analyst (CySA+) certification verifies that successful candidates have the knowledge and skills required to configure and use threat detection tools, perform data analysis and interpret the results to identify vulnerabilities, threats and risks to an organization, with the end goal of securing and protecting applications and systems within an organization. Let us help you bridge this gap, and leave you prepared for the certification exam (CS0-002).

TechNow is a CompTIA partner uses official CompTIA CySA+ curriculum.
