E-Business Security Concerns The Internet can seem like an entrepreneur's dream come true. The Web offers instant access to millions of consumers around the world and the ability to set up a virtual store, which can limit start-up costs. While the Web does offer a powerful platform for launching new ventures, e-businesses are subject to a variety of unique security concerns.

If you and another person want to encrypt messages, should you provide that person with your public 7 Relate Windows Encryption and Hashing to Confidentiality and Integrity key, private key, or both? You should both provide each other with your public keys. 2. What does GPG allow you to do once it is installed? GPG allows you to encrypt and decrypt data and generate public and

SYMMETRIC ENCRYPTION This is also referred to as Secret Key Encryption. In this type of encryption a secret word which could either be a number, word or string of characters is applied to the text of a message to change the content in a particular way such as shifting each letter by a number of places in the alphabet but both the sender and the receiver should know the secret key in order to encrypt and decrypt all messages that use this key. Symmetric Encryption is more efficient and is more efficiently

stations. A list of these authentication methods is listed below i) (OSA) Open System Authentication – provides no authentication and allows for a wireless station to associate with an access point using a random generated shared key. ii) (SKA) Shared Key Authentication – Follows a sequence of actions to authenticate a station attempting to establish an association. iii) (EAP) Extensible Authentication Protocol – Developed to add security to point-to-point (PTP) communications

Smartphone, Malicious code, Keylogger, I. INTRODUCTION Threats against electronic and financial services can be classified into two major classes: credential stealing and channel breaking attacks [20]. Credentials such as users’ identifiers, passwords, and keys can be stolen by an attacker when they are poorly managed. For example, a poorly managed personal computer (PC)

* R3. From a service perspective, what is an important difference between a symmetric-key system and a public-key system? From a service perspective the difference between a symmetric-key system and a public-key system the thing that stands out to me the most is in a symmetric key system both the person sending and the person receiving know the key while in a public key system the decryption key is only know by the receiver. * R29. Stateful packet filters maintain two data structures

and PINs. A stronger password is usually one consisting of at least one of the following; Upper-case and Lower-case letters, numbers and other random symbols found on a keyboards. Identity theft can also occur through the implication of spyware or a key logger on to your PC; as a result simply keeping your PC protected at all times can significantly reduce this risk. Firewall Impact on Site Performance Although firewalls protect ones PC from hackers and malicious software alike, they can at times
