By identifying active hosts and potential entry points, network scanning provides a clearer picture of the network's layout and security vulnerabilities. On the other hand, reconnaissance refers to the broader phase of information gathering, which may include both passive and active techniques to collect intelligence about a target. During the survey, ethical hackers and security professionals may gather data through open-source intelligence (OSINT), social engineering, or even network traffic analysis without direct interaction with the target systems.

The primary aim of the survey is to understand the target's environment, identify potential weaknesses, and plan an effective attack strategy. While network scanning is a more focused and technical approach, reconnaissance encompasses a wider array of techniques that contribute to the overall understanding of the target's security landscape.

Conclusion

Scanning plays a vital role in cybersecurity, enabling organizations to assess their security posture and identify vulnerabilities within their systems and networks. The two primary types of scanning, active scanning and passive scanning, each offer unique advantages and serve different purposes in the security assessment process. Active scanning provides real-time insights by actively probing systems for vulnerabilities, while passive scanning allows for stealthy monitoring of network traffic and behavior without causing disruptions.
