How To Test Your Dansguardian, Safesquid, POESIA, Parental Internet Filter Or We-Blocker Keyword Filter Anytime Anywhere
Author: Webmaestro • Tags: linux, security • Comments: 4How To Test Your Dansguardian, Safesquid, POESIA, Parental Internet Filter Or We-Blocker Keyword Filter Anytime Anywhere Keyword filters block unwanted web pages on the basis of potentially fallen words found in them. However, to be sure that a page is indeed offensive, keyword filters nowadays are not designed to block sites on the basis of just about any potentially offensive word. Instead they measure the number of potentially offensive phrases and often the number of times they occur so as to allow a limited number of occurrences in pages such as those on anatomy, forms requiring gender information, crime reports, statistical reports, administrative information, art etc. The leading keyword blockers like Dansguardian which is extremely popular on Linux or SafeSquid which is popular on Linux and Windows use this method known as a weighed keyword score.

How To Configure Apache To Use Radius For WiKID Two-Factor Authentication On Ubuntu
Author: nowen •
Tags: apache, linux, security, ubuntu, web server •
Comments: 0 How To Configure Apache To Use Radius For WiKID Two-Factor Authentication On Ubuntu This document describes how to add WiKID two-factor authentication to Apache 2.x using mod_auth_radius on Ubuntu 12.04 Precise. It is recommended that you consider using mutual https authentication for web applications that are worthy of two-factor authentication. Strong mutual authentication means that the targeted website is authenticated to the user in some cryptographically secure manner, thwarting most man-in-the-middle attacks. The use of cryptography is key. While some sites use an image in an attempt to validate a server, it should be noted that any man-in-the-middle could simply replay such an image.
