Security Threats Of Network Security - 1412 Words

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†¦show more content†¦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 crac k 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: 802.11 wireless network detector named Kismet, which is a wireless LAN detector named NetStumbler which uses 802.11b and WireShark for analyzing a network. In order to secure a wireless network from intruders several measures has to be taken care while implementing wireless network within the organization.Encryption algorithms are used to encrypt data over wireless network so that network cannot be easily read by the attackers. There are several authentication techniques that can be implemented to secure data over wireless networks such as: biometric technique, OTP method and Single Sign on techniques are used. Attackers use several methods to crack wireless passwords like brute forcing, so as to secure passwords strong passwords with special characters and keys has to be used making it difficult to crack.Wi-Fi Protected Access (WPA) or Wired Equivalent Privacy[4] (WEP) encryption is used by most of the
