Nmap provides a number of features for probing computer networks, including host discovery and service and operating system detection. These features are extensible by scripts that provide more advanced service detection, [7] vulnerability detection, [7] and other features. Nmap can adapt to network conditions including latency and congestion ...
hping is an open-source packet generator and analyzer for the TCP/IP protocol created by Salvatore Sanfilippo (also known as Antirez). It is one of the common tools used for security auditing and testing of firewalls and networks, and was used to exploit the idle scan scanning technique (also invented by the hping author), and now implemented in the Nmap Security Scanner.

Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing, formerly known as BackTrack. [2] Parrot Security OS is a cloud-oriented Linux distribution based on Debian and designed to perform security and penetration tests, do forensic analysis, or act in anonymity. It uses the MATE Desktop ...
Exploits take advantage of a vulnerability by compromising or destructing the vulnerable system, device, or application. Remediation is the process of repairing or providing a remedy for a vulnerability, thereby eliminating the risk of being exploited. Vulnerability scanning is used to identify and evaluate the security posture of a network.
Passive OS Fingerprinting method and diagram. TCP/IP stack fingerprinting is the remote detection of the characteristics of a TCP/IP stack implementation. The combination of parameters may then be used to infer the remote machine's operating system (aka, OS fingerprinting), or incorporated into a device fingerprint.
However, if a UDP packet is sent to a port that is not open, the system will respond with an ICMP port unreachable message. Most UDP port scanners use this scanning method, and use the absence of a response to infer that a port is open. However, if a port is blocked by a firewall, this method will falsely report that the port is open. If the ...
A number of Linux distributions include known OS and application vulnerabilities, and can be deployed as targets to practice against. Such systems help new security professionals try the latest security tools in a lab environment. Examples include Damn Vulnerable Linux (DVL), the OWASP Web Testing Environment (WTW), and Metasploitable.
