Lay a foundation for success with Tested Reference Architectures developed by Fortinet’s experts. Learn more in this white paper.
Moving to the cloud brings new challenges. How can you manage a larger attack surface while ensuring great network performance? Turn to Fortinet’s Tested Reference Architectures, blueprints for designing and securing cloud environments built by cybersecurity experts. Learn more and explore use cases in this white paper.
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.
YAWCU is a wireless LAN (WLAN) capture + WEP cracking utility. It can crack 64/128 Bit WEP keys on IEEE 802.11b/g networks by monitoring WLAN traffic and computing the resulting WEP key once enough packets have been gathered
raddump interprets captured RADIUS packets to print a timestamp, packet length, RADIUS packet type, source and destination hosts and ports, and included attribute names and values for each packet.
Simple-to-use, dynamic, rule-based firewall addition. Uses QUEUE/userspace to dynamically approve or drop packets based on custom rules. With frequency caching, friend/foe indication, loose IP matching, and customizable logging.
sentinel is a network traffic monitor. You can monitor specific
packets to/from network interfaces, internet protocol addresses
and also define specific filters for protocol, port and flag
properties of a packet. Output can be directed to database,
p
AirSnort is a wireless LAN (WLAN) tool which cracks encryption keys on 802.11b WEP networks. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.
The Nemesis Project is designed to be a command line based, portable human
IP stack for UNIX-like and Windows systems. The suite is broken down by
protocol, and should allow for useful scripting of injected packets from
simple shell scripts.
SHMAX is a small sniffing system that is especially designed for system administration and security purpose : SHMAX can easily detect desired packets on the network and react following its configuration, allowing many multiple usages, with full control.
Transform your applications and workflows into powerful agentic systems at global scale.
Gemini Enterprise Agent Platform lets you rapidly build, scale, govern and optimize production-ready agents grounded in your organization's data. The platform enables developers to build custom or pre-built agents for virtually any use case. New customers get $300 in free credits.
trafanal monitors your complete network offering realtime statistics who sends/recvs how much packets/bytes from whom
its a really good placed on a router, showing you who takes which bandwidth, and who made how much traffic
Fwpass is a daemon that executes commands in response to specific sequence of incoming IP packets. It does not use TCP/IP sockets but relies on ULOG functionality of Netfilter (Linux kernel built in firewall).
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.
A suite of tools (a sniffer, a TCP hijacker, an ARP poisoner and a TCP tunnel through ICMP/IGMP packets) created for testing TCP/IP weakness and using them in a non-conventional way. [Up to now I've done only the sniffer-related part]
echolot implements a packet sniffer that grabs ARP packets on any ethernet devices. This empowers your box<br>
* to detect intruders (new mac in lan)<br>
* to find your boxes on foreign lans (known mac in lan)
Guarddog is user friendly firewall management utility for KDE on Linux. It allows you to simply specify which protocols should be allowed between which groups of computers and requires no knowledge of port numbers or packets. Uses ipchains or iptables.
Packet Flood Generator as the name stands is a projet to produce a
threaded traffic generator program, it has support for generating IP, TCP , UDP, ICMP and IGMP packets, also has as feature to keep the connection up.
Pace-ICMP is a utility that can allow X amount of ICMP (ping, etc) packets travel to the host, once X is exceeded, all ICMP traffic is blocked. This allows ping and traceroute functionality, while still protecting you against ICMP attacks.
The main idea behind the Security tool is to analize
network traffic, packets and maybe configuration errors (something like SATAN).
Intended platform is Linux. I'm seeking help to write this tool
from scratch, maybe with a GUI under kde. The textmod
Yavipind is a secure tunnel aka 2 peers securely forwarding
packets toward each other.It is what most people calls a VPN (virtual private
network).
It forwards any kind ofpacket (IPv4, IPv6 or other) sent over the virtual
network interface (e.g. t
a *simple* libpcap program that dumps network packets in a variety of formats. If you are a programmer, this is a good starting point for you to build your own programs.
[NOTE: In the CVS repository there is a version with *alot* of features added]
Enpct (Easy Network Packet Crafting Tool) allows you to generate network packets to check firewalls or other network equipment. The packets can be precisely described in configuration files. It also supports fragmentation based network attacks.
ethernet host availibality monitoring (logging to sql/file)
