OSSEC HIDS : An Open Source Host-based Intrusion Detection System OSSEC HIDS performs log analysis, integrity checking, rootkit detection, time-based alerting and active response. In addition to its IDS functionality, it is commonly used as a SEM/SIM solution. Because of its powerful log analysis engine, ISPs, universities and data centers are running OSSEC HIDS to […]
KisMAC : A A GUI passive wireless stumbler for Mac OS X This popular stumbler for Mac OS X offers many of the features of its namesake Kismet, though the codebase is entirely different. Unlike console-based Kismet, KisMAC offers a pretty GUI and was around before Kismet was ported to OS X. It also offers
Arpwatch : Keeps track of ethernet/IP address pairings and can detect certain monkey business Arpwatch is the classic ARP man-in-the-middle attack detector from LBNL’s Network Research Group. It syslogs activity and reports certain changes via email. Arpwatch uses LibPcap to listen for ARP packets on a local ethernet interface.
Ike-scan : VPN detector/scanner Ike-scan exploits transport characteristics in the Internet Key Exchange (IKE) service, the mechanism used by VPNs to establish a connection between a server and a remote client. It scans IP addresses for VPN servers by sending a specially crafted IKE packet to each host within a network. Most hosts running IKE
RKHunter : An Unix Rootkit Detector RKHunter is scanning tool that checks for signs of various pieces of nasty software on your system like rootkits, backdoors and local exploits. It runs many tests, including MD5 hash comparisons, default filenames used by rootkits, wrong file permissions for binaries, and suspicious strings in LKM and KLD modules.
Angry IP Scanner : IP address and port scanner Angry IP Scanner is a small open source Java application which performs host discovery (“ping scan”) and port scans. The old 2.x release was Windows-only, but the new 3.X series runs on Linux, Mac, or Windows as long as Java is installed. Version 3.X omits the
Firewalk : Advanced traceroute Firewalk employs traceroute-like techniques to analyze IP packet responses to determine gateway ACL filters and map networks. This classic tool was rewritten from scratch in October 2002. Note that much or all of this functionality can also be performed by the Hping2 –traceroute option.
RainbowCrack : An Innovative Password Hash Cracker The RainbowCrack tool is a hash cracker that makes use of a large-scale time-memory trade-off. A traditional brute force cracker tries all possible plaintexts one by one, which can be time consuming for complex passwords. RainbowCrack uses a time-memory trade-off to do all the cracking-time computation in advance
LSoF : LiSt Open Files This Unix-specific diagnostic and forensics tool lists information about any files that are open by processes currently running on the system. It can also list communications sockets open by each process. For a Windows equivalent, check out Process Explorer from Sysinternals.
Pwdump : A window password recovery tool Pwdump is able to extract NTLM and LanMan hashes from a Windows target, regardless of whether Syskey is enabled. It is also capable of displaying password histories if they are available. It outputs the data in L0phtcrack-compatible form, and can write to an output file.
SolarWinds : A plethora of network discovery/monitoring/attack tools SolarWinds has created and sells dozens of special-purpose tools targeted at systems administrators. Security-related tools include many network discovery scanners, an SNMP brute-force cracker, router password decryption, a TCP connection reset program, one of the fastest and easiest router config download/upload applications available and more.
IDA Pro : A Windows or Linux disassembler and debugger Disassembly is a big part of security research. It will help you dissect that Microsoft patch to discover the silently fixed bugs they don’t tell you about, or more closely examine a server binary to determine why your exploit isn’t working. Many disassemblers are available,
Core Impact : An automated, comprehensive penetration testing product Core Impact isn’t cheap (be prepared to spend tens of thousands of dollars), but it is widely considered to be the most powerful exploitation tool available. It sports a large, regularly updated database of professional exploits, and can do neat tricks like exploiting one machine and
EtherApe : EtherApe is a graphical network monitor for Unix modeled after etherman Featuring link layer, IP and TCP modes, EtherApe displays network activity graphically with a color coded protocols display. Hosts and links change in size with traffic. It supports Ethernet, FDDI, Token Ring, ISDN, PPP and SLIP devices. It can filter traffic to
Xprobe2 : Active OS fingerprinting tool XProbe is a tool for determining the operating system of a remote host. They do this using some of the same techniques as Nmap as well as some of their own ideas. Xprobe has always emphasized the ICMP protocol in its fingerprinting approach.
OpenSSL : The premier SSL/TLS encryption library The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and open source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. The project is managed by a worldwide community
WebInspect : A Powerful Web Application Scanner SPI Dynamics’ WebInspect application security assessment tool helps identify known and unknown vulnerabilities within the Web application layer. WebInspect can also help check that a Web server is configured properly, and attempts common web attacks such as parameter injection, cross-site scripting, directory traversal, and more.
