Network Security Toolkit 1.5.0

Network Security Toolkit 1.5.0


Network Security Toolkit is a bootable ISO live CD and its based on Fedora Core 2. more>>
Network Security Toolkit is a bootable ISO live CD and its based on Fedora Core 2.
The toolkit was designed to provide easy access to best-of-breed Open Source Network Security Applications and should run on most x86 platforms.
The main intent of developing this toolkit was to provide the network security administrator with a comprehensive set of Open Source Network Security Tools. The majority of tools published in the article: Top 75 Security Tools by insecure.org are available in the toolkit.
What we find rather fascinating with NST is that we can transform most x86 systems (Pentium II and above) into a system designed for network traffic analysis, intrusion detection, network packet generation, wireless network monitoring, a virtual system service server, or a sophisticated network/host scanner.
This can all be done without disturbing or modifying any underlying sub-system disk. NST can be up and running on a typical x86 notebook in less than a minute by just rebooting with the NST ISO CD. The notebooks hard disk will not be altered in any way.
NST also makes an excellent tool to help one with all sorts of crash recovery troubleshooting scenarios and situations.
Enhancements:
- We are pleased to announce the latest NST release: v1.5.0. This release is based on Fedora Core 5 using the Linux kernel 2.6.18. Here are some of the highlights for this release: the NST Web User Interface (WUI), has been greatly enhanced and cleaned up; extensive additions to managing and analyzing network packet captures; the ability to setup and manage printers; the ability to easily mount many different supported file system types; the ability to manage the NST as a file server (both NFS and CIFS); the addition of the Inprotect package (a Nessus manager); the addition of the Zabbix package (another network resource monitoring tool - similar to Nagios)....

Network Security Analysis Tool 1.5

Network Security Analysis Tool 1.5


Network Security Analysis Tool is a fast, stable bulk security scanner designed to audit remote network services. more>>
Network Security Analysis Tool is a fast, stable bulk security scanner designed to audit remote network services and check for versions, security problems, gather information about the servers and the machine, and much more.

A manpage providing extensive information on NSAT has been included in the distribution. It is available after a make install, or just by typing man doc/nsat.8 from this dir. It is suggested that you inform yourself at least about the -v (scan verbosity) option and edit the configuration file. To learn about changes in this version, please consult doc/CHANGES.

New to this version is support for distributed scanning. The manpage describes how to do a distributed scan. Note that distributed scanning in this version is just a preliminary, proof-of-concept, implementation with no guarantees for its security, reliability, or performance.

Check for updated vulnerability lists, config files, etc. from
http://nsat.sourceforge.net

Currently, these are lists of vulnerabilities:

nsat.cgi (CGI scripts)
nsat.conf (configuration)
src/mod/snmp.h (SNMP community names)

Network Security Monitor Daemon 4.0

Network Security Monitor Daemon 4.0


The Network Security Monitor Daemon is a lightweight network security monitor for TCP/IP LANs. more>>
The Network Security Monitor Daemon is a lightweight network security monitor for TCP/IP LANs. It will capture certain network events and record them in a relational database. The recorded data is available for analysis through a CGI-based interface.
You can run test version with ./Monitord, just to see how it works. Production version should be run in background, v.g. with nohup ./monitord &. Both versions will accept a device name as a parameter (default: eth0). You can send them SIGHUP at any time to print some stats. If you send SIGTERM, SIGQUIT or SIGINT, all threads will end gracefully.
Enhancements:
- Linux Kernel with "packet sockets" and "socket filtering" support.
- GNU C Library 2 (glibc2) with LinuxThreads support. (integrated in most recent versions).
- Full MySQL, including headers and libmysqlclient_r.
- GNU C Compiler (gcc).
- GNU Make (make).
- Perl (perl).
- Wget (wget).
Enhancements:
- Added chmod 4755 ... in Makefile
- Root should run make now, but not the daemon ;-)
- The daemon will drop root privileges as soon as possible
- (after creating the raw socket with an attached linux socket
- filter and putting the interface in promiscuous mode)
- No threads run with root privileges so its much safer
- (specially the new server thread which reads remote user input)
- Added stats thread
- To calculate/mantain exponential averages
- Added server thread
- It accepts HTTP requests and serves stats in XML
