Ethical Hacking – Scanning Networks focuses on the critical phase that comes after reconnaissance and before exploitation. In this stage, ethical hackers actively interact with target systems to discover live hosts, open ports, running services, operating systems, and vulnerabilities.

Network scanning transforms raw intelligence into a clear technical map of the target environment, enabling precise and effective penetration testing.

What You’ll Learn

The purpose and importance of network scanning
How TCP/IP communication works at a technical level
Identifying live systems and open ports
Different scanning techniques and when to use them
Banner grabbing and OS fingerprinting
Vulnerability scanning and network mapping
Using proxies and anonymization to stay stealthy

Course Modules

1. Overview of Scanning

What scanning is and how it differs from reconnaissance
Why scanning is essential in ethical hacking
Active vs passive scanning
Legal and ethical boundaries

2. Understanding the 3-Way Handshake

How TCP connections are established
SYN, SYN-ACK, and ACK explained
How scanners exploit the handshake process
TCP vs UDP communication

3. Checking for “Live” Systems and Their Open Ports

Host discovery techniques
ICMP, ARP, and TCP-based discovery
Identifying open, closed, and filtered ports
Understanding service exposure

4. Types of Scanning

TCP Connect scanning
SYN (Stealth) scanning
UDP scanning
FIN, NULL, and Xmas scans
Advantages and risks of each method

5. Banner Grabbing and OS Fingerprinting

What banners reveal about systems
Service version detection
Active and passive OS fingerprinting
Why OS detection matters for exploitation

6. Vulnerability Scanning and Drawing Out the Network

Difference between port scanning and vulnerability scanning
Identifying known vulnerabilities
Creating a network topology map
Understanding attack paths

7. Preparing Proxies and Other Anonymizing Techniques

Why anonymity matters during scanning
Using proxies and proxy chains
VPNs, TOR, and traffic obfuscation
Avoiding detection by IDS and firewalls

Who This Course Is For

Ethical hacking beginners moving beyond reconnaissance
Penetration testers and red teamers
Cybersecurity students and SOC analysts
IT professionals wanting offensive security skills

Why Network Scanning Is Critical

Reconnaissance tells you what might exist. Scanning confirms what actually exists.

Accurate scanning allows attackers—and ethical hackers—to:

Identify the weakest entry points
Reduce noise and detection risk
Plan efficient and targeted exploits

Poor scanning leads to failed attacks, false assumptions, and unnecessary exposure.
