How To Hack Wireless Networks
How Are Wireless Networks Hacked? There are two main types of encryptions used. WEP (Wired Equivalent Privacy) Wired Equivalent Privacy (WEP) is a security algorithm for IEEE 802.11 wireless networks. Introduced as part of the original 802.11 standards ratified in 1997, its intention was to provide data confidentiality comparable to that of a traditional wiredRead More
WHAT IS VLAN?
A VLAN (Virtual Local Area Network) is a logical collection of devices such as workstations, servers and network devices that are grouped together in the manner such that they appear to be on the same LAN despite their geographical distribution.

Administrative Configurations of Router
There are three configurations a network administrator should apply to a newly provisioned switch or router. Although application of these configurations may seem like common sense, 90% of devices I see are missing at least one of these settings, and about 75% are missing two or more. Use this checklist as an action item toRead More
What Is Frame Relay?
Frame relay is layer 2 protocol, which is used to connect LANs i.e. Local Area Networks and transfer data across WAN i.e. Wide Area Network. It shares data over the WAN using X.25 technology. How it works? Frame Relay uses the special purpose hardware components including frame routers, bridges & switches which are used toRead More
What Are OSPF Areas and Virtual Links?
Introduction OSPF is an open standard link state protocol which uses Dijkstra algorithm. It is a classless routing protocol, supports VSLM and discontinuous networks by sending subnet mask information as part of a route advertisement. Its administrative distance value is 110. Its hop count is unlimited. It supports only equal cost load balancing. It providesRead More
