Exploring Various Network Scanning Techniques Lab
Exploring Various Network Scanning Techniques Lab
Consider what you have learned so far about Scanning as you review the objectives and scenario below. Complete the lab that follows on EC-Council’s website using the link below.
The objective of this lab is to help you in conducting network scanning, port scanning, analyzing the network vulnerabilities, and so on. You need to perform a network scan to:
- Check live systems and open ports
- Perform banner grabbing and OS fingerprinting
- Identify network vulnerabilities
- Draw network diagrams of vulnerable hosts
Earlier, you gathered all possible information about the target, such as IP address range and network topology.
Now, as an ethical hacker, or pen-tester, your next step will to perform port scanning, network scanning, and vulnerability scanning on the IP addresses you obtained in the information-gathering phase. This will help you to identify IP/hostname, ports, services, live hosts, vulnerabilities, and services running on the target network.
Port scanning will help you to identify the open ports and the services running on specific ports, which involves connecting to TCP and UDP system ports. Port scanning is used to find out the vulnerabilities in the services running on a port.
Vulnerability scanning determines the possibility of network security attacks. It evaluates the organization’s systems and network for vulnerabilities such as missing patches, unnecessary services, weak authentication, and weak encryption. Vulnerability scanning is a critical component of any penetration testing assignment.
The lab this week will provide you with real-time experience in network scanning and vulnerability scanning.
