tonic measures for today and the future EssayThere are many ways to stop war drivers and hackers and these systems whitethorn be as simple or complex depending upon the nature of the network. First, one should understand that war drivers and hackers preempt easily tap into a network because of the plug-and play nature of modern devices. Also some ripe(p) security system systems such as the outfit Equivalency Privacy (WEP) system apply by 802. 11b wireless networks is plagued by some common errors in the system, including failure to engage it entirely by itself or engage WEP encryption key set at default. Thus, method such as WEP, IPSEC, and Wi-fi protected Access, DMZs, Firewalls and Virtual Private Networks go off be established to deter war drivers and hackers (War Driving, 2004). WEP Wired Equivalent Privacy (WEP) is basically a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard (which is 802. 11b) designed to provide the wireless fidelity a security level that matches a wired network. Security for a WLAN can be tricky, as access to a WLAN is not hindered by most physical barriers. WEP works by encrypting data before transmitting it to the wireless network.This encryption can be done in confederation with new(prenominal) protection methods such as password protection, end-to-end encryption and virtual private networks (VPNs) (Wired Equivalent Privacy, 2006). But WEP is not without it flaws, as proven by a research congregation from the University of California at Berkeley. The group was able to intercept and change data transmissions and gone as furthermost as gaining access to restricted networks and data. On the other and, WECA (Wireless Ethernet Compatibility Alliance) claims that WEP is not the only security system method available for WLAN.WEP is popular because most consumers have put up much of their trust in WEP that other methods (Wired Equivalent Privacy, 2006). IPsec IPsec (Internet communications protoc ol Security) is defined as the backbone for a set of security protocols for network communications. IPsec claims to be effective in establishing virtual private networks and remote user access in dial-up accounts and private networks. One obvious advantage of IPsec is that security arrangements can be taken cared of without changing computers or users.CISCO (a major promoter of IPSEC) provides support for IPSEC on their network routers (IPsec, 2005). IPsec has two options for security service. First is the hallmark Header (AH), which basically authenticates the identity of the data sender and the other one is Encapsulating Security Payload (ESP) which handles twain sender trademark and data encryption. Both services packages specific information into packets in a brain that follows the IP packet header. Separate key protocols can be selected for this such as the ISAKMP or Oakley protocol (IPsec, 2005).ISAKMP (Internet Security Association and Key Management Protocol) is a coded protocol base on the IKE key telephone exchange protocol (ISAKMP, 2006). On the other hand, the Oakley protocol is a security system in which two genuine parties can exchange confidential material through the Internet (Oakley Protocol, 2006). Both protocols can be used on a secured connection and is defined by RFC (Request for Comments) 2408 and 2412 respectively. Wi-Fi Protected Access Wi-Fi Protected Access (WPA) is a new security protocol that was designed to replace WEP. It is technically an better version of WEP.Though WPA has improved data protection features, WEP is still considered to be best for domicil use. However, WEP is not recommended for corporate use because it is given to eavesdropping and hacking, because it is not able to handle the bulk of data that WPA is capable of handling. WPA uses Temporal Key Integrity Protocol (TKIP) which uses pre-packet mixing function, extended initialization vector, and a re-keying mechanism. WPA is also said to have stronger user identification because it is based on 802. 1 xs and has an Extensible Authentication Protocol (EAP).Also WPA relies on RADIUS (a central authentication server) to identify each user Wi-Fi Protected Access, 2005). WPA is actually under IEEE 802. 11i, and there are rumors that a second version called WPA2 is on the works. It is also predicted that by 2003, there get out be software updates that will allow both the client and server to establish WPA in their system. Hotspots can then operate indoors a mix of WEP and WPA modes to support both home and corporate clients. In case of a home client, the identification system would be simpler than the one that will be issued for corporations (Wi-Fi Protected Access, 2005).
