Remote Nmap (Rnmap) package contains both client and server programs.
Actual idea for this sofware is that various Rnmap clients can connect to
one centralized Rnmap server and do their portscannings.
Server utilize Nmap scanner.
Gobbler: A tool to audit DHCP networks
Includes DHCP rogue server detection, DHCP DoS, distributed spoofed port scanner using DHCP to obtain many source IP addresses, mulitple arp scans, filtered port detection, spoofed OS detection (nmap + port 0)
The FreePKI project aims to create practical, interoperable & free code and services for Certificate and Registration Authorities based on the X.509 standard, including nearly zero-cost ID verification through a PGP-like web of trust scoring system.
New to Google Cloud? Get $300 in credits to explore Compute Engine, BigQuery, Cloud Run, Gemini Enterprise Agent Platform, and more.
Start your next project with $300 in free Google Cloud credit. Spin up VMs, run containers, query petabytes in BigQuery, or build agents with Gemini Enterprise Agent Platform. Once your credits are used, keep building with 20+ always-free tier products including Compute Engine, Cloud Storage, GKE, and Cloud Run functions. No commitment required—just sign up and start building.
The sandbox system call API is a simple yet powerful mechanism for
confining untrusted code. It is similar to chroot() and BSD jails, but has
much greater flexibility and expressive power. The code is mostly complete
but not yet fully functional.
RSA Public Key Crypotgraphy for Web Browsers.
Use JavaScript to RSA-encrypt data that can only be decrypted on the server, and not by prying eyes.
The poor man's SSL...
This is a program that watches your system log files, looking for hack attempts. It instanty reacts to potential security breaches by (for instance) adding firewall rules to cut off the attacker.
QT based Linux web security tool that it is designed to test targets for weak passwords using crack, leech and URL testing functions. Plugins allow potentially any protocol (eg http, ftp) or server to be attacked, while remaining anonymous using proxys.
DSBL-helper. Tries to send a special formatted test message to Distributed Server Boycott List through every suspect IP found in complain using several mechanisms (SMTP, HTTP, telnet, SOCKS etc) and reports in.
Everything you need to build production-ready agents and models. Access 200+ Google and third-party AI models and tools.
Gemini Enterprise Agent Platform is Google Cloud's comprehensive platform for developers to build, scale, govern, and optimize agents and models. Choose from Google's most advanced models and third-party models like Anthropic's Claude Model Family.
Protowatch is a userspace extension to Linux\'s 2.4 iptables firewalling code. Userspace will dynamically start a server to accept the packet, and log whatever the client sends. Useful for discovering what protocols are in use.
Seahorse is a Gnome front end for GnuPG. It is a tool for secure communications and data storage. Data encryption and digital signature creation can easily be performed through a GUI, and Key Management operations also can be performed.
Sanctum allows you to run virtual servers on your computer so you can test the security of software by actually breaking into it. Developers just create a virtual server image and let hackers download it and try their hardest to find exploits.
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.
Libike is a cross-platform C library for managing IKE negotiations.The library implements RFC-standard ISAKMP/IKE exchanges and utilizes callbacks to delegate tasks of the packet transmission and security policies management to the external code.
jRevProxy is a lightweight reverse proxy server fully written in Java. jRevProxy accepts HTTP and HTTPS requests and translates these into new requests based on a set of rules. HTTPS with client side authentication (X509 certificates) is supported.
OpenSST (Open Simple Secure Transaction) is a project to create a simple security protocol for making transaction between (un)trusted parties. The project includes a protocol design specification and a cross-platform software implementation of the speci
sechk - SEcurity CHecKer
It is a powerful and useful tool to check if you got exploited and rooted, it will use checksum comparation via md5 sum, it exchanges file lists and csums from the sechk server. It\'s gonna work with all posixes and unixes.
The Secure Remote Log Monitor (SRLM) project provides client and server
utilities that collect application or system log files from multiple systems over an untrusted network onto a central server for analysis and action.
PKS is an OpenPGP Public Key Server. It allows users to store and lookup public keys from the server's database. It can also synchronize with other servers. (This product includes software developed by Marc Horowitz.)
Project aims to develop an Apache HTTP Server module that implements the WS-Security specification. It will enable the Apache HTTP Server to identify SOAP messages that include WS-Security information and thereby check security credentials.
CryptoPy is a pure python implmentation of cryptographic algorithms and applications. The algorithms are developed for readability more than speed. The collection now includes IEEE 802.11i specific algorithms that generated the test vectors for 802.11i.
