    2 Network Security Threats and Potential Measures As the technology is growing the security threats are also increasing at higher rate. So, as to protect an organization from such network security threats severe actions and several steps have to be taken by network security administrators. In any large organization that is having large number of big servers, firewalls and interconnected network of hundreds of computers, security is one of the most important aspects so as to secure its network from intruders. Within the organization, all the computers and 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 network from intruders because there are several ways intruders can sniff the network and resulting in heavy loss of data. There are several threats that can affect network security of an organization such as: Wireless Sniffing, DoS (Denial of Service), sniffing of VoIP network , trojans and unauthorized access to FTP server. Wireless Sniffing and potential measures to secure wireless Networks In today’s business scenario, within the organization most of the operations taken place over a wireless network such as transferring data between systems using wireless, accessing internet and sending Mails over Internet. Large number of rooters is used for providing internet access and wireless access to computers. Consider a situation, in which if one of the network get sniffed by attacker. By sniffing a single wireless network, an intruder can access all the incoming and outgoing traffic over that wireless network resulting in heavy loss of confidential data to an organization. If any intruder able to crack firewall and he will be able to access wireless network’s internal network and can read all the confidential data and also can inject malicious packets in the network so as to route the packets to some other destinations. There is large number of tools available in the market through which a wireless network [1] can be cracked and sniffed such as: 8 02.11 wireless network detector named Kismet, which is a wireless LAN detector named NetStumbler which uses 802.11b and WireShark for analyzing a network.
