At the center of this framework is the OpenVAS Scanner which executes the actual Network Vulnerability Tests (NVTs), served with daily updates via the OpenVAS NVT Feed.

The OpenVAS Manager is the service that consolidates plain vulnerability scanning into a full vulnerability management solution. The Manager controls the Scanner via OTP and itself offers the XML-based, stateless OpenVAS Management Protocol (OMP).

All intelligence is implemented in the Manager so that it is possible to implement various lean clients that will behave consistently e.g. with regard to filtering or sorting scan results. The Manager also controls a SQL database (sqlite-based) where all configuration and scan result data is centrally stored.

For a full feature list, screenshots and download, see this section of the Open Vas website.

Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.

It is widely used by network administrators and just curious users around the world, including large and small enterprises, banks, and government agencies.

It can analyze and test your hardware from top to the bottom and assure that it won’t fail easily under the production stress.

Inquisitor is:

* Flexible: you can adjust just about any parameter in analysis or testing process and customize the system to the widest extent.
* Modular: it’s made up from a series of interchangeable modules; one can easily add new modules to add new tests, detections, production steps, etc.
* Intelligent: server-based version includes a database that stores all the data on all computers that were tested by Inquisitor. If only some parts of hardware will change, clever scheduler won’t redo all the long testing, but only tests relevant to hardware changes.
* Distributed: due to modular architecture, Inquisitor can be easily distributed across a cluster to distribute load or make a geographically distributed system.
* Scalable: it could be helpful to analyse/test just one home computer or all the computers in your organization, up to multiple thousands computers in manufacturing enterprise.
* Free as in speech: the base platform is distributed under the GPL license.
* Mature: Inquisitor is based on a rock-solid Linux technology and is under active development since 2004. There are multiple production enterprise installations relying on it.

The following are some reasons why you might consider using Eraser:

“Your first thought may be that when you ‘delete’ the file, the data is gone. Not quite, when you delete a file, the operating system does not really remove the file from the disk; it only removes the reference of the file from the file system table. The file remains on the disk until another file is created over it, and even after that, it might be possible to recover data by studying the magnetic fields on the disk platter surface.

Before the file is overwritten, anyone can easily retrieve it with a disk maintenance or an undelete utility.

There are several problems in secure file removal, mostly caused by the use of write cache, construction of the hard disk and the use of data encoding. These problems have been taken into consideration when Eraser was designed, and because of this intuitive design and a simple user interface, you can safely and easily erase private data from your hard drive.”

Its main features include the following:

Creates a virtual encrypted disk within a file and mounts it as a real disk.

Encrypts an entire partition or storage device such as USB flash drive or hard drive.

Encrypts a partition or drive where Windows is installed (pre-boot authentication).

Encryption is automatic, real-time (on-the-fly) and transparent.

Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:

- 1) Hidden volume (steganography – more information may be found here).

- 2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data).

Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS.

Features:
- Disable Windows ‘calling home’
- Disable questionable services
- Disarm Internet Explorer
- Disarm Windows Media Player
- Remove Windows Messenger
- Improve privacy and security
- Improve performance

Though xpy is smaller than 60 kilobytes, it can close serious threats (i.e. DCOM) on long distance, where large service-packs can only protect you until a new security hole has been found.
