What is the difference between symbolic link and hard link? Explaining the difference between a symbolic link or a symlink and a hard link is easy and vital to knowing about how Linux/Unix environments work. Understanding the difference between a symbolic link and a hard link is also important for web server maintenance and understanding how modern websites work.

FollowSymLinks is a directive in your web server configuration that tells your web server to follow so called symbolic links. As one would expect, FollowSymLinks is an acronym for Follow Symbolic Links. FollowSymLinks is a very important setting that plays a role in your website security.

ISO 27001 is a standard providing model for an implementation of an effective Information Security Management System (ISMS). ISO 27001 is also known under its more precise name ISO/IEC 27001:2005 and is closely related to another norm known under the name ISO 27002. Both ISO 27001 and ISO 27002 are together the standards that are used by organizations to implement systems to improve the security of their information and data.

How easy is it to obtain MAC address and IP address from wireless network traffic? We have asked this question and now provide this writeup to demonstrate how vulnerable MAC addressing is as a security measure. Even though the number of users protecting their wireless networks with the MAC filtering technique as the only measure is decreasing, there are still many of them.

Setting up and configuring WPA security depends on the scale of your network and the robustness of security that is sought to be implemented. Setting up WPA for a large corporation that most likely involves also authentication services is a different story than setting up WPA for a small business or home network. Enabling WPA for your home or small business network can be accomplished relatively easy. This page describes setting up WPA-TKIP in Windows with emphasis on Windows XP.
