Nmap and Wireshark for Network Scanning
What Is Nmap?
Nmap (Network Mapper) is a widely used open-source tool for network discovery and security auditing, capable of identifying live hosts, open ports, running services, and operating systems on a network.
Common Nmap Use Cases
| Use Case | Description |
|---|---|
| Host Discovery | Identifying which devices are active on a network |
| Port Scanning | Finding open ports and the services running on them |
| OS Fingerprinting | Determining the likely operating system of a target |
| Service Version Detection | Identifying software versions to spot known vulnerabilities |
What Is Wireshark?
Wireshark is a network protocol analyzer that captures and displays network traffic in detail, allowing security professionals to inspect packets, troubleshoot issues, and detect suspicious or malicious activity.
Using Wireshark for Security Analysis
Analysts use Wireshark to examine unencrypted traffic for sensitive data exposure, identify unusual communication patterns, and investigate potential intrusions by reviewing captured packet data in depth.
Once a network has been mapped and its traffic analyzed, the next step in testing is often attempting to exploit discovered vulnerabilities - which is where Metasploit comes in.
