A wireless LAN or WLAN is a wireless local area network‚ which is the linking of two or more computers or devices without using wires. WLAN uses spread-spectrum or OFDM modulation technology based on radio waves to enable communication between devices in a limited area‚ also known as the basic service set. This gives users the mobility to move around within a broad coverage area and still be connected to the network. For the home user‚ wireless has become popular due to ease of installation‚ and

three types of security protection‚ MAC filtering‚ WEP‚ and authentication. Each has a different way to secure the network against unauthorized access. MAC filtering allows only traffic from specific client stations to pass through the network based on their unique MAC addresses (Coleman & Westcott‚ 2012). This gives the administrator the ability to lock the network down to only the devices they want on the network‚ giving another layer of security. WEP‚ or wired equivalent privacy‚ uses a hexadecimal

The computer kiosks were poorly secured; the kiosks were accessible from the back which made them vulnerable to tampering. The computer firewalls set up did not block malicious traffic coming from the kiosks. The wireless network used an old encryption system (WEP)‚ which was easy for hackers to crack. The kiosks should have been placed in a secure area of the

There are many security issues that come under Wi-Fi . The main problem that it has till now is that it is easy for hackers to attack the network. The security method that is used now is the WEP (Wired Equivalent Privacy).The new VPN (Virtual Private Network) method seems to correct everything that is wrong with WEP. -1- Wireless Fidelity INTRODUCTION Wi-Fi‚ or Wireless Fidelity is freedom :it allows you to connect to the internet from your couch at home‚ in a hotel room or a conferance room

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

security allowed the hackers to attack specific stores just by using a laptop and an antenna which permitted the thieves access to the central database. As it was mentioned in the business case‚ TJX was using (WEP) as the security protocol and it is well-known in the e-commerce arena that WEP encryption can be deciphered in less than one minute which makes it very unreliable and risky for business transactions. Last but not least‚ TJX failed to encrypt customer data. • Auditors: it is concerning that

merchants’ company credit card systems. Further investigation revealed that these breaches at TJX could be traced back to 2003. Some key factors driving this situation included the following: TJX’s lack of cybersecurity sophistication (i.e. use of WEP‚ severs always in administrator mode‚ etc.) Overall lack of awareness by the consumer in terms of steps taken to mitigate breach risks Unpredictable and inconsistent standards set by PCI DSS CASE FACTS AND ANALYSIS The key challenges TJX faced was
