Q: What is Network Scanning?
A: Network scanning is a set of procedures used for identifying hosts, ports, and services in a network.

Q: What are the objectives of Network Scanning?
A: To discover live hosts, IP addresses, open ports, operating systems, system architecture, running services, and vulnerabilities.

Q: Name the three main types of Network Scanning.
A: Port Scanning, Network Scanning, Vulnerability Scanning.

Q: What is Port Scanning?
A: Port Scanning lists the open ports and services by sending messages to probe TCP and UDP ports of the target system.

Q: Define Network Scanning.
A: Network Scanning identifies active hosts and their IP addresses in a network.

Q: What does Vulnerability Scanning do?
A: Vulnerability Scanning detects known vulnerabilities by comparing the target system against a database of known exploits.

Q: What is the SYN flag in TCP communication?
A: The SYN (Synchronize) flag is used to initiate a connection.

Q: What does the ACK flag indicate?
A: The ACK (Acknowledgment) flag confirms the receipt of a packet.

Q: What is the function of the PSH flag?
A: The PSH (Push) flag indicates that data should be pushed to the receiving application immediately.

Q: What does the URG flag signify?
A: The URG (Urgent) flag marks data that should be prioritized.

Q: What is the purpose of the FIN flag?
A: The FIN (Finish) flag is used to gracefully close a connection.

Q: When is the RST flag used?
A: The RST (Reset) flag is used to abruptly terminate a connection.

Q: What is Nmap used for?
A: Nmap is a versatile tool used for network exploration and security auditing, identifying live hosts, open ports, services, and operating systems on a network.

Q: What is the primary use of Hping3?
A: Hping3 is used for TCP/IP packet crafting and network analysis, supporting various scanning techniques such as ICMP, ACK, UDP, and SYN scans.

Q: What is Metasploit?
A: Metasploit is an open-source project that aids in penetration testing and vulnerability assessment, automating the discovery and exploitation of vulnerabilities.

Q: What does NetScanTools Pro offer?
A: NetScanTools Pro is useful for network discovery and monitoring.

Q: Name some mobile scanning tools.
A: IP Scanner for iOS, Fing for Android and iOS, and Network Scanner for Android.

Q: What is an ARP Ping Scan?
A: ARP Ping Scan detects active devices on a local network.

Q: How does an ICMP Ping Scan work?
A: ICMP Ping Scan uses echo requests to identify active hosts on a network.

Q: What is a TCP Ping Scan used for?
A: TCP Ping Scan checks for live hosts by sending TCP packets.
