Osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. The tools make low-level operating system analytics and monitoring both performant and intuitive. Osquery exposes an operating system as a high-performance relational database. This allows you to write SQL queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.Osquery queries your devices like a database. Osquery uses basic SQL commands to leverage a relational data-model to describe a device. Frequently, attackers will leave a malicious process running but delete the original binary on disk. This query returns any process whose original binary has been deleted, which could be an indicator of a suspicious process.

A simple yet powerful Syslog protocol Server & Analyzer. Can be tuned to only log events under a threshold, or to directly mail and admin when another threshold value is reached. The events can be viewed by hosts, by severity, or by facility. It can't be used as a service from Windows Server 2008 and newer due to their different security policy.

Automated network based hard disk drives / storage devices erasure is server based software which installs on a central server. Server is connected to network switches and several PXE boot enabled workstations are attached to the network. As soon as the workstation is powered on, it boots off the network via the server and begins wiping all the attached hard disk drives. Once all the hard drives are wiped, data related to each hard disk is stored in the central server’s database.

A graphical interface for watching IIS log files. Makes copies of the current logfile at given intervals which gives the impression of realtime monitoring of the server traffic.

NetComp Scan comes with 7 tools to make life easier ComputerInfo - Allows you to get basic information from remote computer including last logged on user, storage device info, time since last restart, and installed programs. IP info - Ping allows you to get your computer IP information including public IP and also allows you to ping like cmd. MAC Changer - Changes MAC with option to revert to default. Ping Sweep - Sweeps a specified network range and returns online devices. Port Scanner - Scans a specified port range on a networked device and returns open/ closed ports. Uptime Monitor - Add multiple hosts and monitor real time "online" status with easy to see color scheme. Wifi Scan - Scan for wifi AP's and list all devices found. AP's are discovered by BSSID so you can see every AP around you. This tool also allows you to create log files for multiple AP's to help monitor your networks. A complete description of what each tool does can be found in the help menu

360-FAAR (Firewall Analysis Audit and Repair) is an offline, command line, firewall policy manipulation tool to filter, compare to logs, merge, translate and output firewall commands for new policies, in Checkpoint dbedit, Cisco ASA or ScreenOS commands, and its one file! Read Policy and Logs for: Checkpoint FW1 (in odumper.csv / logexport format), Netscreen ScreenOS (in get config / syslog format), Cisco ASA (show run / syslog format), 360-FAAR compares firewall policies and uses CIDR and text filters to split rulebases / policies into target sections and identify connectivity for further analysis. 360-FAAR supports, policy to log association, object translation, rulebase reordering and simplification, rule moves and duplicate matching automatically. Allowing you to move rules to where you need them. Build new rulebases from scratch with a single 'any' rule and log files, with the 'res' and 'name' options. Switch into DROPS mode to analyse drop log entries.

VScan is a small, text-based, platform independent port scanner written in python, which supports multithreading and banner grabbing.

One of the biggest issues we have as ArcSight administrators is knowing what's going on with our connectors. A connector may be "up and running" but actually it has not sent a single event in weeks. Also, many single connectors collect events from multiple locations (multi database, multi file, WUC) and we might never know one of these locations is unavailable as events from the other locations are arriving so the connector seems to be working fine. Eventually, when we do understand that something is wrong, it takes a while to analyze, understand and solve. In light of these problems in the process of error detection in connectors, I have developed is an automated tool named 'We! Analyze' with its own UI which analyzes connector logs manually or using an API that can be started from the command line, a schedule task or from the console with an action in rule, tool or integration command (if you use the API you can forward the events to a syslog listener in CEF format).
