Tools Description of Concept of Hacking – Scanners
GFI Lan Guard:-
GFI LANguard™ scans your network and ports to detect, assess and correct security vulnerabilities with minimal administrative effort. As an administrator, you have to deal separately with problems related to vulnerability issues, patch management and network auditing, at times using multiple products. However, with GFI LANguard these three cornerstones of vulnerability management are addressed in one package. This gives you a complete picture of your network set-up and help you to maintain a secure network state faster and more effectively. Vulnerability Management , Patch Management ,Network Auditing
The Nessus® is a vulnerability scanner for active scanners, featuring high-speed discovery, configuration auditing, asset profiling, sensitive data discovery and vulnerability analysis of your security posture. Nessus scanners can be distributed throughout an entire enterprise, inside DMZs and across physically separate networks.
Net Tools is a comprehensive set of host monitoring, network scanning, security, administration tools and much more, all with a highly intuitive user interface. It’s an ideal tool for those who work in the network security, administration, training, internet forensics or law enforcement internet crimes fields.
Nmap (“Network Mapper”) is a free and open source utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are avalable for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), and a utility for comparing scan results.
