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.

Grid computing can be defined as a type of parallel and distributed system that enables sharing, selection, and aggregation of geographically distributed autonomous resources. Grid resources are assigned dynamically at runtime depending on their availability and capability.

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.

Implementing the proper wireless security standard, devising a sound wireless architecture plan, and setting up a VPN and tunneling protocols is a very good way to tackle the task of keeping your wireless network and data secure. There are even more wireless security configurations that can be done to strengthen your security even further.

IPSec, VPN, and wireless architecture are the words that take wireless network security to the next level. Securing your wireless network is as important as having a good lock on your office door. Getting data or services from unsecured (open) networks is very easy, and breaking into WEP secured networks is fairly accomplishable. The current wireless security WPA and WPA2 standards provide relatively good security layer; however, it is only a matter of time before the community of hackers develops approaches to get into WPA networks as well.

WPA (or Wi-Fi Protected Access) is today the security standard in wireless networking that is rapidly replacing the older WEP (Wired Equivalency Privacy) standard. WPA and its younger sibling WPA2 are newer standards based on the IEEE 802.11i ratified amendment set out to improve some of the disadvantages of WEP. This wireless security standard is playing today a vital role in the security of wireless networks.

Even though wireless or Wi-Fi network security is the bread and butter of today's IT Wi-Fi infrastructure, many networking specialists still fear wireless networks because of horror stories from around the world. However, these horror stories happen only in unprotected and unsecure wireless networks. Protected and well managed wireless networks can be almost as reliable as physical wired networks, and we hope this wireless network security tutorial can help you to achieve your security goals.

How to crack WEP with Intel PRO/Wireless 3945ABG is a task that can employ you for a long time. The Intel PRO/Wireless 3945ABG network adapter driver that comes from the manufacturer does not provide packet injection and network monitoring capabilities which are needed to crack WEP, and therefore before you attempt WEP cracking efforts, you have to update your driver first which can be a daunting task.
