losetup-utils are three bash scripts that attempt to make the use of losetup a bit easier and faster. losetup can be fast, easy, and practical if you need to transport sensitive information over the Internet or in CD's, DVD's, or a pendrive. Also, if you want to store private data on your hard disk or in the cloud, an encrypted volume can be a convenient choice. The types of encryption can be any installed on the system.
CIRCLean aims to be used by someone receiving a USB key from an untrusted source who wants to see the content without opening the original and potentially malicious files. The code runs on a Raspberry Pi, which means it is never required to plug the original USB key into a computer.
CacheGuard Appliance is an all-in-one OS appliance providing firewall, antivirus, caching, compression, bandwidth allocation, load balancing, reverse and forward proxy, high availability, Web application firewall, URL guarding, and more. It can be purchased as an OS to install on your server, as an OS to run in a virtual machine, or as a hardware appliance.
FireHOL a simple yet powerful way to configure stateful iptables firewalls. It can be used for almost any purpose, including control of any number of internal/external/virtual interfaces, control of any combination of routed traffic, setting up DMZ routers and servers, and all kinds of NAT. It provides strong protection (flooding, spoofing, etc.), transparent caches, source MAC verification, blacklists, whitelists, and more. Its goal is to be completely abstracted and powerful but also easy to use, audit, and understand.
Frankenwall is a bash shell script intended to create a highly secure IPTables based Linux firewall/router with QOS/traffic shaping/bandwidth management. Be certain you know exactly what your network needs before using it. The primary focus of this project is security through an intimate understanding of your networking requirements. All configuration is done by editing text files.
HLBRW is an acronym for Hogwash Light BR Watch. It is a tool to help make rules for HLBR. In other words, HLBRW was made to be used by HLBR users needing make new rules. It requires some expertise with HLBR, the TCP/IP protocol suite, and regular expressions. HLBRW is a script started by iwatch (a system events watch program) when the HLBR event log is modified. The concept is very single: if the HLBR log was modified, then a known attack was blocked. But the attacker might take other subsequent actions unknown by HLBR. When HLBRW starts, it will coordinate a tcpdump session to record the traffic generated by the attacker's IP address for the next few minutes. If the recorded traffic isn't relevant (without a push in TCP or another relevant protocol), the created file will be deleted. Based on the recorded traffic, the network security manager can make new rules. HLBRW is part of the HLBR project, an intrusion prevention system (IPS) used in firewall systems.
IP-Array is a Linux iptables firewall script written in bash. It allows the creation of precise, stateful rules, while remaining easy to configure. IP-Array supports VPN, traffic shaping (creation of custom HTB and SFQ qdiscs, classes, and filters), multiple external interfaces, multiple LANs, multiple DMZs, NAT, logging, MAC address matching, packet marking, syslog logging, and various sysctl settings. It also includes some presets and autoconfig options for common needs like DNS, FTP, SMTP.
