About this course

Cybersecurity is no longer optional; it is a critical core skill for every IT and business professional. As cyber threats like ransomware, phishing, data breaches, and insider attacks grow more sophisticated, organizations urgently need people who understand how to detect, respond to, and prevent security incidents.This beginner-friendly course, Foundations of Cybersecurity Operations, provides a clear and practical introduction to the essential principles, tools, and practices used to safeguard systems, networks, and sensitive data. Led by expert instructor Gleb Marchenko, you’ll explore key concepts including the CIA triad (confidentiality, integrity, availability), risk management frameworks, identity and access management (IAM), and the structure and role of the Security Operations Center (SOC).You’ll also learn how to detect and analyze threats using modern tools like SIEM and XDR, build secure access controls with multi-factor authentication, and recognize human vulnerabilities that attackers frequently exploit.

Real-world examples, hands-on labs, and interactive activities ensure that you not only understand the theory but also know how to apply it effectively in practice.By the end of this course, you’ll have the confidence to identify risks, strengthen defenses, and support your organization’s overall security posture. Whether you’re aspiring to start a career in cybersecurity or want to enhance your IT knowledge, this course equips you with the strong foundations needed for long-term success.

AI systems introduce security challenges that are fundamentally different from anything traditional cybersecurity was built to handle. LLM applications, retrieval pipelines, vector databases, and agent based automations create new vulnerabilities that can expose sensitive data, enable unauthorized actions, and compromise entire workflows. This course gives you a complete and practical framework for securing GenAI systems in real engineering environments.You will learn how modern AI threats operate, how attackers exploit prompts, tools, and connectors, and how data can leak through embeddings, retrieval layers, or model outputs. The course walks you through every layer of the AI stack and shows you how to apply the right defenses at the right places, using a structured and repeatable security approach.What you will learnThe full AI Security Reference Architecture across model, prompt, data, tools, and monitoring layersHow GenAI attacks work, including injection, leakage, misuse, and unsafe tool executionHow to use AI firewalls, filtering engines, and policy controls for runtime protectionAI SDLC best practices for dataset security, evaluations, red teaming, and version managementData governance strategies for RAG pipelines, ACLs, encryption, filtering, and secure embeddingsIdentity and access patterns that protect AI endpoints and tool integrationsAI Security Posture Management for risk scoring, drift detection, and policy enforcementObservability and evaluation workflows that track model behavior and reliabilityWhat is includedArchitecture diagrams and control mapsModel and RAG threat modeling worksheetsGovernance templates and security policiesChecklists for AI SDLC, RAG security, and data protectionEvaluation and firewall comparison frameworksA complete AI security control stackA step by step 30, 60, 90 day rollout plan for teamsWhy this course is essentialIt focuses on practical security for real AI deploymentsIt covers every critical layer of modern LLM and RAG systemsIt delivers ready to use tools and artifacts, not theoryIt prepares you for one of the fastest growing and most demanded areas in techIf you need a structured and actionable guide to protecting AI systems from modern threats, this course provides everything required to secure, govern, and operate GenAI at scale with confidence.

AI Security Fundamentals: Risks, Frameworks & Tools

Udemy Instructor

Modern AI applications introduce security challenges that traditional defenses cannot address. LLM based systems, retrieval pipelines, agents, data connectors, and vector databases expose new attack paths that organizations must understand and control. This course gives you a complete, practical, and engineering focused approach to securing GenAI systems across their entire lifecycle.You will learn how attackers exploit AI models, how sensitive data leaks through prompts and outputs, how RAG pipelines can be manipulated, and how misconfigured tools or connectors expose entire environments. The course shows you how to design secure AI architectures, apply the right controls at the right layers, and build a repeatable security process for any AI powered system.What this course includesA detailed AI Security Reference Architecture for models, prompts, data, tools, and monitoringFull coverage of GenAI threats: injection attacks, data leakage, model misuse, unsafe toolsPractical guardrail design using AI firewalls, filtering, and permissioningAI SDLC guidance for dataset integrity, evaluations, red teaming, and version controlData governance for RAG systems: access control, filtering logic, encryption, secure embeddingsIdentity and authorization models for AI endpoints and tool integrationsAI Security Posture Management workflows for monitoring risk and driftObservability pipelines for logging prompts, responses, decisions, and quality metricsWhat you getArchitecture blueprintsThreat modeling templatesGovernance and policy frameworksSecurity checklists for AI SDLC and RAGEvaluation and firewall comparison matricesA full AI security control stackA clear 30, 60, 90 day adoption roadmapWhy this course is valuableIt is built for real engineering and real enterprise environmentsIt covers the full AI ecosystem instead of focusing on a single controlIt provides the exact artifacts professionals need to secure AI systemsIt prepares you for one of the most in demand skill sets in modern techIf you need a practical, structured, and comprehensive guide to securing LLM and RAG applications, this course gives you the tools, knowledge, and processes required to protect AI systems with confidence and to operate them safely at scale.

Software architecture

Udemy Instructor

The architecture describes the processes and structures of the entire project, determining the data throughput in different parts of the project, and allows you to optimize and scale the project in the future.Good architects are often people who learn from even better architects. Perhaps this is because some conceptual requirements are inherent in almost all projects. Each conceptual requirement is formulated as a question that the architect must ask himself during the project. Of course, some systems may have their own additional critical conceptual requirements.We will get to know the types of software architectures. We will be able to create our own simple software architecture. We will be able to use and expand the software architecture. As a result, this course will be useful not only for architects or people who plan to become one. And, technical leaders of the development group, developers of different levels and testers.In first section, I reveal the main objective of the course. In second section you will be introduced to the types of software architectures. In third section you will be able to create his own simple software architecture. In forth section you will be able to use and extend the software architecture. In fifth section the nuances of software architecture will be considered. Six section will help you understand which part of the course will be most useful to you.Course Topics and Structure:1. Introduction2.
