security features compared to IPv4, new security threats faced by IPv6 and some solutions to improve IPv6 security. INTRODUCTION Internet Protocol version four (IPv4) was introduced by International Engineering Task Force (IETF) is 1981 via RFC 791 as a feasible solution to connect computers for communication. With a 32 bit address space covering 2^32 addresses, it was considered sufficient to provide an IP address to all users over the world. But with the requirement of IP for various technologies
or research online, browse the web or participate in Internet forums. How does VPN work? There are many different protocols that VPN service providers use to keep their clients anonymous. Each one of these protocols has a slightly different way of keeping data and online communications secure. Protocols used by VPN services include: IP Security (IPSec) - either using tunneling or transport mode to securely encrypt data. IPSec is often used along with other
Virtual private networks (VPN) provide an encrypted connection between distributed sites over a public network (e.g., the Internet). By contrast, a private network uses dedicated circuits and possibly encryption. The basic idea is to provide an encrypted IP tunnel through the Internet that permits distributed sites to communicate securely. VPN's permit secure, encrypted connections between a company's private network and remote users through a third-party service provider. A VPN can grow to accommodate
The Secure Shell (SSH) is a protocol to use the network services with security. For example, when an email is send or receive, SSH will automatically encrypt or decrypt the email so that attacker will not intercept in the middle of the transaction [1]. There are two versions of SSH i.e. SSH1 and SSH2. SSH has 3 main components as shown in figure 1: Transport Layer Protocol that provide confidentiality, integrity and authentication; User Authentication Protocol that authenticate client to the server;

Introduction Wireless security is a complex field, but employing a few simple defenses will leave a network far safer against attackers. A wireless local area network (WLAN) is a local area network using high-frequency radio signals to wirelessly connect two or more devices, often to the internet via a wireless access point within a limited geographical area. The millions of WLANs all across the world can be found in homes, coffee shops, and even in international enterprises. Most of the WLANs deployed
E-commerce: Security and Privacy As the evolution of the internet and purchasing online becomes popular, so do the security factors that contribute to the ways of eliminating fraud, theft, and acquiring personal information. E-commerce has created many new ways for customers to make payments including e-cash, e-cheques, and e-wallets. In the 21st century, many organizations worked hard at securing communications and payments made through e-commerce transactions. In doing so, customers would
