In this module, we will delve into the core concepts of networking that are essential for effective network scanning and security. We will begin with an overview of port scanning techniques, followed by an in-depth look at the OSI Model. You'll gain a solid understanding of the Network and Transport Layers, and we will conclude with a detailed analysis of TCP header flags and the TCP 3-way handshake, critical for ensuring reliable data communication.

In this module, we will explore a range of host discovery techniques crucial for network reconnaissance. Starting with ping sweeps, we will cover various methods including TCP SYN and ACK pings, UDP ping scans, and ARP ping. We will also delve into the use of ICMP ECHO and Timestamp pings, IP Protocol pings, and conclude with an in-depth look at traceroute and reverse DNS resolution. This section provides the tools needed to effectively discover and map hosts within a network

In this module, we will dive into advanced scanning techniques using Nmap. You'll learn to set up a virtual hacking lab and deploy Metasploitable3 VM images for hands-on practice. We'll cover a variety of scan types, including default scans, TCP Connect, SYN, and UDP scans, as well as more sophisticated techniques like OS detection, service detection, and aggressive scanning. Additionally, you'll explore options for verbosity, output, logging, and visualizing scan results with WebMap. This section equips you with the skills to conduct thorough and efficient network scans.

In this module, we will cover the techniques for detecting and evading firewalls during network scanning activities. You will learn how to use ACK probing to identify firewall presence, employ packet fragmentation to circumvent security barriers, and specify MTU settings to fine-tune your evasion methods. Additionally, we will explore the use of IP decoys to mask scanning origins and MAC address spoofing to conceal the identity of your devices. This section equips you with advanced strategies to navigate and bypass network defenses.In this module, we will cover the techniques for detecting and evading firewalls during network scanning activities.

In this module, we will focus on enhancing the timing and performance of your scans using Nmap. You'll learn how to apply timing templates to streamline scan operations, utilize parallelism to execute multiple scans concurrently, and configure host timeout settings to control scan durations. Additionally, we will explore adjusting scan delay to ensure efficient scanning without overloading the network. This section provides the tools to maximize the effectiveness and efficiency of your scanning activities

In this module, we will introduce you to the Nmap Scripting Engine (NSE) and its powerful capabilities for network scanning and automation. You'll learn the syntax and structure of NSE scripts, making it easier to understand and modify them. We'll explore the different script categories and their specific uses, enabling you to select the right scripts for your tasks. Additionally, you'll gain the skills to develop custom NSE scripts, enhancing Nmap's functionality to suit your unique requirements. This section equips you with the knowledge to leverage NSE for advanced scanning and automation.

In this module, we will dive into service enumeration techniques to extract detailed information about network services. You'll learn to perform banner grabbing, utilize Whois and traceroute for network enumeration, and conduct FTP and SMTP enumeration. We will explore DNS enumeration techniques, including zone transfers and brute-forcing, and delve into HTTP enumeration for identifying methods, hidden files, and WAFs. Additionally, we'll cover SMB and MySQL enumeration, and conclude with vulnerability scanning using Nmap. This section equips you with the skills to thoroughly investigate and analyze network services for security assessments
