Network security fundies Wk 5 bsa310 Introduction The Essence of Network Security: * Allow everything to be accessible and secure at the same time. What exactly does this mean? It means that all your local and network resources need to be made accessible all the time‚ but to only the right people. It is the second part of this statement that causes difficulty. Most administrators have no problem making the resources available‚ but the issue of "to only the right people" is where the

on the wireless network protocol IEEE 802.11 (or Wi-Fi) and its use in managed networks (or Infra-structured) though many of the topics discussed apply to other protocols as well. In our discussions‚ we will conduct a survey of both encryption based and non-encryption based attacks. 1.1 Overview of Wireless Security Through the evolution of wireless networks‚ IEEE 802.11 (or Wi-Fi) has gained popularity as a low cost networking alternative to cabling both in households and offices for setting up

The method of disguising plaintext in such a way as to hide its substance is called encryption. Encrypting plaintext will result to meaningless data called ciphertext. We use encryption in order to hide the information from anyone whom is not intended even if they can see the encrypted data. But maybe you are curious on how your receiver will be able to read the unreadable message? Well if there is encryption‚ there is also decryption which is the reverse‚ in other words‚ moving from ciphertext

Gateway is a backend server which acts like a gateway for mail encryption and decryption with digital signature using industry standards available on open source environment. It is designed to be deployed even on an existing mail server or as a separate backend service where it will provide email security through GPG (open source version of PGP) encryption. Therefore this system will not route emails but will handle only email encryption and decryption. PGP Mail Gateway will serve the purpose of providing

There are different levels of encryptions all with pros and cons. The encryption method is not the only method to provide security to your wireless LAN connections.
