The wireless data is in the air and leaks out beyond the store’s walls. TJX used an encryption code that was developed just as retailers began going wireless. Wired Equivalent Privacy or WEP is a wireless encryption code developed in 1999 that retailers began to implement. Within a couple of years hackers broke the encryption code and rendered WEP obsolete. Many retailers never changed to updated encryption codes such as WPA or WPA2. TJX never upgraded and once hackers got access‚ they were

(CSEC 630 Lab Assignment 1 – Introduction to Cryptography‚ n.d.). Since there are only 25 possible encryptions keys…”if we know how one letter should be deciphered‚ then we can determine the shift and decipher the entire message.” (Bryant & Ward‚ n.d.). Q2.

Network Security Concepts Name NTC 410 Instructor ’s Name November 1‚ 2005 File security falls into two categories‚ encryption and access. Access to files can mean physical access to a computer with unsecured files or access via user permissions or privileges in the form of access control lists (ACLs) (Strengthen Your Users ’ File Security‚ 2003). The files kept on a server with NTFS storage can be locked to prevent anyone who does not have the correct permissions from opening them. This is

1. Which of the following statements is true? a. The concept of defense-in-depth reflects the fact that security involves the use of a few sophisticated technical controls. (Incorrect. The concept of defense-in-depth is based on the idea that‚ given enough time and resources‚ any single control‚ no matter how sophisticated‚ can be overcome—therefore‚ the use of redundant‚ overlapping controls maximizes security.) b. Information security is necessary for protecting confidentiality‚ privacy‚ integrity

ABSTRACT Bluetooth is a wireless protocol utilizing short-range communications technology facilitating data transmissions over short distances from fixed and/or mobile devices‚ creating wireless PANs. Bluetooth provides a way to connect and exchange information between devices such as mobile phones‚ telephones‚ laptops‚ personal computers‚ printers‚ GPS receivers‚ digital cameras. So the security of the Bluetooth becomes very important. We have different types of security for Bluetooth to protect

BitLocker drives can be encrypted with 128 bit or 256 bit encryption‚ this is plenty strong to protect your data in the event the computer is lost or stolen. Windows 7 extends BitLocker functionality to removable drives‚ we call that functionality BitLocker to Go. BitLocker to Go gives you the ability to encrypt

Security of Cloud Computing Abstract The purpose of this paper is to talk about how security concerns of cloud computing matter to business as well as to other organizations and looking for the solution of the problems. Public cloud computing provides immense convenience but at the same time consists of huge privacy and security risks. The paper will discuss this problem from survey done by other researchers and the realistic problems cause by leakage of cloud data. The reason why I decided to pick
