DioNiSio is a DNS scanner written in ANSI C that only depends on sockets library and libc. It implements 3 scan methods (dictionary, massive reverse lookup and recursive zone transfers). Targeted to portability, rational resources usage, and easy use.

A linux kernel implementation of a distributed protocol to provide pro-active defence against Distributed Denial of Service (DDoS) attacks.

DSFS (Distributed Secure File System) is a server-less, redundant, secure, infinite, non-revocable filesystem.

This is a port of FreeBSD divert socket mechanism to linux. This works in conjunction with IPtables and sends packets to user space. Similar to ip_queue but allows any number of unique user space listeners, such as Snort.

An Electronic Shelf Label is a device that's typically attached to the front edge of retail shelving. ESL Firebase Edition V2.0 utilizes the AES-256 in CBC mode and Google Firebase. It doesn't require an expensive gateway to function, once configured, all it needs is a power supply and a Wi-Fi access point. ESL Firebase Edition V2.0 allows you to operate as many of them as you wish, provided that each has its own unique ID, and there's enough power and bandwidth for all of them. For more information please visit https://github.com/Northstrix/Electronic-Shelf-Label-Firebase-Edition You can find the tutorial on V2.0: https://www.instructables.com/DIY-IoT-Electronic-Shelf-Label-With-Google-Firebas-1/ V1.0: https://www.instructables.com/DIY-IoT-Electronic-Shelf-Label-With-Google-Firebas/ The desktop app is made with the help of the ChatGPT.

ExamLog is a Log analyzer, developed for syslog messages. It works on a Unix/Linux console, searching for user defined patterns. ExamLog, can divide and clasify syslog messages, and send them to a remote/local postgresql DataBase.

Server/client suite which provides per-user access control/firewall/QOS. Robust and high speed implementation is secure against MAC/IP spoofing, and can scale to large networks with many clients. Options for additional monitoring and captive portal.

FireWise Utilities (FWU) is a suite of tools for dynamically generating firewall tables in either binary or script format for several operating systems. Features in dev: iptables, ip6tables, ipfw, pf, SHA2 bin hashing and LZO bin compression

Log common Windows trojan attempts (and optionally emulate the trojan). *This project is not actively maintained, and the software is of little use today.*

FSFS is a secure distributed file system in user space built over FUSE and OpenSSL. It stores AND transfers data between clients and server in secure form, leaving most of the cryptography to the clients, thus relieving the server of the additional work.

Fastspy is a multithreaded network port scanner. It minimizes connection idle time performing fast subnet service search, classic port range scan, hosts list scan, and also send user data over a connection to log servers response.

A very configurable GTK based frontend for Iptables. An easy way to configure your firewall in Linux.

Free Agents DIDS is a distributed intrusion detection system that you place on each host on your network. Agents intercommunicate with aes encryption, automatically alert you, and secure your network for free!

A simple and incredibly powerful tool for scripting and fuzzing arbitrary network protocols written using the Chicken Scheme-to-C compiler.

GNIPS is a network intrusion prevention system for Linux using Snort and iptables. It alerts user of incoming attacks on their network and allows them to block any offending hosts. It's also possible to configure GNIPS to send out alert emails.

GTCop Professional Security Appliance aims to provide a powerful tool for satellite communications, with enhanced QoS and bandwidth controls. As derived from IPCop Firewall, it is a stable, secure, easy to configure and maintain GNU/Linux firewall box.

ettercap-gg is a Gadu-Gadu IM ettercap dissector. It is a patch for ettercap sniffer that adds the ability to sniff Gadu-Gadu logins, passwords and messages. Gadu-Gadu (www.gadu-gadu.pl/) is the most widely used IM network in Poland with ~6mln users.

Sidecar is a Kerberos authentication utility used at Cornell University and several other universities. This project is designing a secure GTK+/Gnome utility that is functionally equivalent to the Windows/Mac versions.

gSTM is a front-end for managing SSH-tunneled port redirects. It stores tunnel configurations in a simple XML format. The tunnels (local, remote and dynamic) can be managed and individually started/stopped through one simple interface.

This program is an automated administration tool that allows stranger (or worse, your friends) to connect to you host and create user accounts in a secure manner.

Green Screen: A Linux based Advanced Syslog Server for Juniper NetScreen Firewalls - Can be expanded later to support other products. It can capture syslog messages, parse them, store them in a MySQL database. A Web GUI interface is also included.

Heartbeat Light is a lightweight Heartbeat-like daemon/client. It supports monitoring of of multiple Services like HTTP, FTP ... it can be extended quite easy. Heartbeat Light is completely written in ANSI C.

nf-HiPAC is a high performance packet filter for Linux. It provides the same rich feature set as iptables but uses an advanced algorithm to minimize the number of memory lookups per packet.

Honeybrid is a network application built to 1) administrate network of honeypots, and 2) transparently redirect live network sessions (TCP or UDP) from one primary destination host to a secondary destination host.

An alternative Identification system that is a replacement for Microsoft's Passport and the Liberty Alliance. Its a simple architecture that is setup so anyone can run a server and thereby have control over their online identification.
