2Network Security Threats and Potential MeasuresAs the technology is growing the security threats are also increasing at higher rate. So, as toprotect an organization from such network security threats severe actions and several steps have to betaken by network security administrators. In any large organization that is having large number of bigservers, firewalls and interconnected network of hundreds of computers, security is one of the mostimportantaspectsso as to secure its network from intruders.Within the organization, all the computersand devices are interconnected in a LAN network or using a WLAN (Wireless Local Area Network). So,the most important task of network security administrator to secure its internal as well as external networkfrom intruders because there are several ways intruders can sniff the network and resulting in heavy lossof data.There are several threats that can affect network security of an organization such as: WirelessSniffing, DoS (Denial of Service), sniffing of VoIP network, trojansand unauthorized access to FTPserver.Wireless Sniffing and potential measures to secure wireless NetworksIn today’s business scenario, within the organization most of the operations taken place over a wirelessnetwork such as transferring data between systems using wireless, accessing internet and sending Mailsover Internet. Large number of rooters is used for providing internet access and wireless access tocomputers. Consider a situation, in which if one of the network get sniffed by attacker. By sniffing asingle wireless network, an intruder can access all the incoming and outgoing traffic over that wirelessnetwork resulting in heavy loss of confidential data to an organization.If any intruder able to crackfirewall and he will be able to access wireless network’s internal network and can read all the confidentialdata and also can inject malicious packets in the network so as to route the packets to some otherdestinations.There is large number of tools available in the market through which a wireless network[1]can be cracked and sniffed such as:802.11 wireless network detector namedKismet, which is a wirelessLAN detectornamedNetStumblerwhich uses802.11b and WireShark for analyzing a network.
