Collax Business Server is an all-in-one Linux server for small- and medium-sized businesses. It delivers all the important network services within a heterogeneous business environment for communication, infrastructure, compliance, groupware, and storage, all in a reliable and secure way which is easy to manage. It also provides essential security functions such as firewalling and virus and spam filtering, to protect against hacker attacks, viruses, and unsolicited email messages.
cpm (Console Password Manager) is a small console tool to manage passwords and other sensitive data and store them in a public-key encrypted file. It also allows you to configure the whole hierarchy yourself, so it's easily adoptable for many requirements. The encryption is handled through GnuPG, and the data inside is stored as XML.
CKS is an openPGP (RFC2440) compliant public key server. It is currently under development. It is written in C, and runs on Linux. It uses PostgreSQL for key storage, and supports the hkp protocol (it can interface with GnuPG and NAI PGP). The keyserver is mostly functional, and there is a link to a running copy on the homepage.
Cyan Secure Web Proxy Server is a carrier grade, high performance Internet filtering proxy server for Linux. It includes scalable (user/group/host) Web filter and virus scan utilities for blocking malicious applications at the gateway. It has an advanced URL database, authentication support (Active Directory, LDAP, NTLM), SSL Interception, easy deployment, and remote administration.
EverCrack is a cryptanalysis engine. The overall design goal is to systematically break down complex ciphers into their simplex components for cryptanalysis (by the kernel). The kernel consists of an algebraic design (comparison and reduction) for breaking uniliteral, monoalphabetic ciphers instantaneously. Currently, it can break a 4000-word cipher in milliseconds. EverCrack currently has multi-language support for the user interface and cracking encryption in other language dictionaries (English, German, French, Spanish, Italian, Swedish, Dutch, and Portuguese).
INSERT (the Inside Security Rescue Toolkit) aims to be a multi-functional, multi-purpose disaster recovery and network analysis system. It boots from a credit card-sized CD-ROM and is basically a stripped-down version of Knoppix. It features good hardware detection, fluxbox, emelfm, links-hacked, ssh, tcpdump, nmap, chntpwd, and much more. It provides full read-write support for NTFS partitions (using ntfs-3g), and the ClamAV virus scanner (including a fairly recent signature database and a GUI). It provides partition handling with gParted and also has a network boot facility.
KisKis (Keep It Secret! Keep It Safe!) is an easy-to-use password manager. It allows the user to manage passwords for many different purposes, including network or Internet accounts, credit-card pin-numbers, and password-secured files. The accounts can be grouped hierarchically within a tree structure. Each account can be described by multiple attributes (such as user name or URL), file attachments, and comments. The history of each password change can be tracked. All passwords are stored in a single XML file using OpenPGP messages.
LinOTP is a solution for strong two-factor authentication with one time passwords. It features a modular architecture into which UserIdResolver, authentication, and OTP calculation modules can be plugged. It includes UserIdResolver modules for LDAP/AD, SQL, and flat file user databases, and authentication modules for PAM and RADIUS. New modules can be developed easily. Supported tokens are HMAC-OTP/HOTP (RFC 4226/ OATH compliant), Aladdin eToken PASS, eToken NG-OTP, Safeword Alpine, Google Authenticator, motp, SMS OTP/Mobile TAN, and a Simple Pass token for users without token hardware. TOTP is supported, along with a new algorithm for daily passwords for applications not supporting RADIUS. CLI, Web, and GTK+ GUI clients are available for management. LinOTP features multi-client capability, redundancy, and a self-service portal. It has been used with PAM for local and SSH logins, Apache, VPN, and Windows Terminal Server, and is OATH certified.
