get onto the system that is not on the list it will not be allowed. That is why smaller systems can keep up with this type of format. Another way to protect your WLAN is with WPA (WI-FI Protected Access). WPA is an upgrade to the WEP(Wired Equivalent Privacy). WEP regulates access to wireless network through a devices hardware-specific MAC address. After the site survey is done and the security measures are determined and implemented a business should feel confident in their WLAN. This being

It/205 week five assignments 1. List and describe the security controls in place. Where are the weaknesses? The TJX was still using the old wired equivalent Privacy (WEP) encryption system‚ which is relatively easy for hackers to crack. An auditor also later found the company had neglected to install firewalls and data encryption‚ on many of the computers using the wireless network‚ And did not properly install another layer of security software it had already purchased .TJX also retained

network‚ the number of frames required can be obtained by re-injection in less than a minute. The required computational effort is approximately 220 RC4 key setups‚ which on current desktop and laptop CPUs is negligible. 1 Introduction Wired Equivalent Privacy (WEP) is a protocol for encrypting wirelessly transmitted packets on IEEE 802.11 networks. In a WEP protected network‚ all packets are encrypted using the stream cipher RC4 under a common key‚ the root key1 Rk. The root key is shared by all

INFORMATION SYSTEMS AND SECURITY AUDIT 1. Define the following terms: (6 Marks) -Integrity In information security‚ integrity means that data cannot be modified undetectably. This is not the same thing as referential integrity in databases‚ although it can be viewed as a special case of Consistency as understood in the classic ACID model of transaction processing. Integrity is violated when a message is actively modified in transit. Information security systems typically provide message integrity

Question 1:- Compare and contrast wired and wireless LANs. What unique concerns must be addressed by the designer of a wireless networks. Answer 1:- Introduction: LAN is a local Area Network and a computer network covering a small physical area‚ like a home‚ office‚ restaurant or small group of buildings‚ such as a school‚ a college or an airport. Although a LAN can be used as an isolated network to connect computers in an organization for the sole purpose of sharing resources‚ most LANs today

Wired For Distraction The use of technology is increasing drastically in today’s teens and young adults‚ but what exactly is the combination of cell phones‚ computers‚ IPads‚ and video games doing besides distracting kids from real life? In the article “Wired for Distraction” by Dalton Conley‚ he tells us what technology is doing to our future. He explains what it is doing to our culture and how it is changing it.

Wired and Wireless‚ What’s the Difference? The main difference between a wired and wireless data communication infrastructure is the existence of physical cabling. The same or similar techniques are employed for both types of data communication infrastructure in terms of the core elements of essential network services. The basic difference between a wired and a wireless network is self-explanatory. A wired network uses wires to communicate whereas a wireless network uses radio waves. Another difference

In The Wired Generation‚ Wade Jacobsen and Renata Forste write about the impact of online communication versus face to face communication and the impact of electronic media on grades. According to the authors‚ electronic use can distract from academic success‚ and at the same time facilitates social interaction and the development of social networks (Jacobsen and Forste 279 ) . The authors succeed in supporting the positive effects on social interaction and fails to support the negative effects to

Wired and Wireless Media Wired and wireless media both provide means of transporting data. Though both provide benefits in certain areas‚ neither is particularly better than the other. It is important for organizations to utilize both methods of media to maximize what benefits each provides while minimizing that same media types short comings. Anders (2010) uses six metrics to compare wireless and wired media: range‚ installation effort and flexibility‚ data volume‚ availability of information in
