Introduction Voice over IP (VoIP) is the transmission of voice over packet-switched IP networks, as of right now it is one of the most prominent emerging trends in the revolution of telecommunications (Thermos, 2009). Almost everyone one is driven by technology in one way or the other. With this drastic growth in technology over the pass years and with this rapid growth in advancement it as also presented many ground-breaking improvements; which have contributed significantly to the simplification

solution had to be introduced to ensure security. Wired Equivalent Privacy (WEP) was introduced to meet this need. WEP is a means to secure Wireless Local Area Networks (WLANs) by encrypting transmissions at the data-link layer with the symmetric RC4 encryption algorithm. The main goal when employing WEP was to provide confidentiality, access control, and data integrity at an equivalent level as a wired connection, thus the name. These security standards were

the hash value is not specified. There are roughly two types of collision attacks. The first is a Collision attack where it finds two different messages that produce the same hash value. Second one is a Chosen-prefix collision attack: Much like symmetric-key ciphers are vulnerable to brute force attacks, every cryptographic hash function is inherently vulnerable to collisions using a birthday attack. Due to the birthday problem, these attacks are much faster than a brute force would be. A hash of n

1. Name all the security services provided in a network communication. There are several ways to provide security in the network communications. There are different network security technologies and techniques that help to maintain the security in your network such as IPSec, cryptography, SSL, Kerberos, Certificates, PKI, firewall, antivirus solutions and the physical security. Secure communication is necessary to maintain the integrity of the data. A specialized field in computer networking

2005 Sem B 3.b) [8 marks] To give access to authorized people are under four categories. What are they? Gives one example for each category. Answer: 1. What You Have • This means of authentication is based on your having a physical thing. • Example: A key, badge, token, or plastic card. 2. What You Know • Many systems verify authorized access based on what you know. • Example: A password, identification number, or the correct combination of numbers on locks. 3. What You Do • This mode of authorized access
