Answer:
Zenmap is a graphical user interface (GUI) for the Nmap (Network Mapper) tool, which is commonly used for network discovery and security auditing. The "Intense Scan" in Zenmap is a predefined Nmap scan profile that is designed to provide a comprehensive view of the services and open ports on a target system.
The purpose and results of the "Intense Scan" in Zenmap can be summarized as follows:
1. **Service Enumeration**: The primary purpose of the Intense Scan is to enumerate and identify all the services and open ports running on the target system. This information helps network administrators and security professionals understand the services that are accessible from the network.
2. **Version Detection**: The Intense Scan also attempts to detect the version of the services running on open ports. Knowing the service versions can be crucial for security assessments, as it allows for the identification of vulnerabilities associated with specific software versions.
3. **Script Scanning**: Nmap can also run scripts during the scan to gather additional information about the target system, such as potential vulnerabilities, service banners, or other valuable details. This can aid in assessing the security posture of the target.
4. **Operating System Fingerprinting**: In addition to service scanning, the Intense Scan may also include operating system fingerprinting. This means it tries to identify the target's operating system based on characteristics of the network responses, which can be valuable for understanding the diversity of systems on a network.
5. **Aggressive Timing**: The Intense Scan uses more aggressive timing and parallelism settings compared to other Nmap scan profiles. This allows it to complete the scan faster but may increase the risk of detection by intrusion detection systems (IDS) or causing network congestion.
6. **Comprehensive Report**: After the Intense Scan is completed, Zenmap provides a detailed report that summarizes the results, including open ports, services, version information, and any script or operating system fingerprinting results. This report is valuable for network administrators and security analysts to assess the network's security posture.
It's important to note that while the Intense Scan can provide a comprehensive view of a target system's services and potential vulnerabilities, it should be used responsibly and only on systems for which you have explicit permission or authorization to scan. Unauthorized scanning of systems can be considered illegal and unethical. Always follow ethical hacking guidelines and obtain proper authorization before conducting any network scanning activities.
