Study Notes

Network Fundamentals

Networking Concepts: Understanding protocols (TCP/IP, UDP), OSI model layers, network topologies (bus, star, ring, mesh), addressing schemes (IP addressing, MAC addressing), and routing protocols.
Network Devices: Functions of routers, switches, hubs, firewalls, and network interface cards (NICs). Their roles in data transmission and network security.
Network Security: Basic security concepts including firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS), access control lists (ACLs), and VPNs. Understanding common network attacks and vulnerabilities.
Network Troubleshooting: Common network problems and troubleshooting steps such as connectivity issues, slow speeds, and packet loss. Learning to interpret error messages and logs.

Security Fundamentals

Security Threats: Identifying various threats such as malware (viruses, worms, Trojans), phishing, denial-of-service (DoS) attacks, social engineering, and man-in-the-middle attacks.
Security Controls: Methods of security implementation such as antivirus software, intrusion detection/prevention systems, firewalls, access controls, and user authentication.
Security Policies and Procedures: Understanding the importance of establishing security policies and procedures to mitigate risks and protect sensitive data.
Compliance Standards: Familiarization with security standards and regulations like HIPAA, PCI DSS, GDPR, and others.
Data Encryption: Understanding encryption methods like symmetric and asymmetric encryption, and their roles in securing data transmission and storage.
Access Control: Different access control models (ACLs, RBAC, ABAC), and their importance in securing resources.
Vulnerability Assessment: Learning about the process of identifying and mitigating vulnerabilities in systems and applications.
Risk Management: Understanding risk assessment procedures and implementing controls to mitigate potential security risks.

Cloud Concepts

Cloud Computing Models: Different cloud service models (IaaS, PaaS, SaaS), their characteristics, and use cases. Understanding the benefits and drawbacks of each model.
Cloud Deployment Models: Public, private, hybrid, and community cloud deployments, and their applications.
Cloud Security: Addressing security concerns in cloud environments, including data breaches, identity theft, unauthorized access, and compliance issues.
Virtualization: The role of virtualization in cloud computing, and concepts like hypervisors and virtual machines (VMs).
Cloud Storage: Different cloud storage solutions, their characteristics, and use cases, such as object storage, file storage, and block storage.
Cloud Networking: Setting up networks within cloud environments, understanding virtual private clouds (VPCs), and cloud-based DNS services.
Cloud Monitoring and Management: Tools and technologies used for monitoring and managing cloud resources.

Automation And Programmability

Automation Tools: Understanding tools used for automation in IT systems, including scripting languages like Bash, Python, and PowerShell for automating tasks and processes.
Configuration Management: Concepts related to configuration management systems (like Ansible, Puppet, Chef) and their use in maintaining and deploying systems consistently.
Infrastructure as Code (IaC): Using code to manage and deploy infrastructure, promoting consistency and reducing errors. Technologies associated with IaC (like Terraform, CloudFormation).
Orchestration Tools: Cloud orchestration tools (like Kubernetes) that automate the deployment, scaling, and management of applications and services.
Integration with Programming Languages: Integrating automation tools and scripts with programming languages to build comprehensive automation solutions.

Programming Basics
