- Frustrate port scanners using portspoof.
The portspoof program is designed to enhance OS security through emulation of legitimate service signatures on otherwise closed ports. It is meant to be a lightweight, fast, portable and secure addition to the any firewall system or security infrastructure.
The general goal of the program is to make the port scanning software (Nmap/Unicornscan/etc) process slow and output very difficult to interpret, thus making the attack reconnaissance phase a challenging and bothersome task.

- SIPVicioussuite is a set of tools that can be used to audit SIP based VoIP systems. It currently consists of four tools:
- svmap – this is a sip scanner. Lists SIP devices found on an IP range
- svwar – identifies active extensions on a PBX
- svcrack – an online password cracker for SIP PBX
- svreport – manages sessions and exports reports to various formats
- svcrash – attempts to stop unauthorized svwar and svcrack scans
- Ip phone Scanning Made Easy (ISME) scans a VOIP environment, adapts to enterprise VOIP, and exploits the possibilities of being connected directly to an IP Phone VLAN. It seeks to get the phone’s configuration file directly from a TFTP server, enable SIP/SIPS (TCP/UDP), communicate with an embedded Web server and Web server banner, identify the editor by MAC address, and identify potential default login/password combinations which should be changed.

- CHScanner is an ARP, IPv4 and IPv6 network scanner with 31 scan methods: it scans for open ports, protocols, NetBIOS information’s and Windows shares, SNMP information, and WMI (WBEM) information. CHScanner can turn on a remote Windows host (using Wake-On-LAN) or shut it down or reboot it. CHScanner an automatic (scriptable) working mode, a hunt mode, a passive mode, and the normal scanning mode.
- SoftPerfect Network Scanner is a free multi-threaded IP, NetBIOS and SNMP scanner with a modern interface and many advanced features. It is intended for both system administrators and general users interested in computer security. The program pings computers, scans for listening TCP/UDP ports and displays which types of resources are shared on the network (including system and hidden).
