Recently I spotted a piece of news about a type of network attack combining techniques we have discussed in recent articles involving Google Hacking and Buffer Overflow Attack . The incident, according to Forbes News1 involves “using Google searches to track down sites vulnerable to so-called ‘SQL injections’.” Essentially, the hackers use Google to hunt […]

The Domain Name System (DNS) relies on a hierarchical database system. At the top of this system sit thirteen root servers with names following the format letter.root-servers.net, where the letter ranges from A to M. Many people mistakenly assume that there are only 13 root servers in the world. In fact, each root server notation […]

What does the name Trojan Horse imply in way of network security, and what threats do Trojan Horses bring to a network computing system?

What are RADIUS AAA Servers? According to Convery, S.(2007)1: “RADIUS was developed by Livingston Enterprises (now part of Alcatel-Lucent) in the early 1990s, became an Internet standard through the IETF in 1997, and today is the most widely accepted AAA protocol. Another widely adopted AAA protocol, which predates RADIUS as an RFC by four years, […]

PPTP port belong to Point-to-Point Tunneling Protocol (PPTP). PPTP is a method for implementing virtual private networks that works on the data link layer. It serves the purpose of encrypting a remote computer’s network traffic to a host using Point-to-Point Protocol’s (PPP’s) authentication methods of PAP (Password Authentication Protocol) or CHAP (Challenge-Handshake Authentication Protocol). It […]

Domain Name System (DNS) is the magical ability of Internet hosts to translate the machine-readable IP address numbers like 216.109.112.135 to something meaningful to humans, like www.yahoo.com. A sophisticated hierarchical database system in the Internet is required to accomplish this task. One of the core components of that system is the DNS server, which serves […]

TCP/IP (Transmission Control Protocol / Internet Protocol) is a set of communications protocols that implement the protocol stack on which the Internet and most commercial networks run. However, from a security standpoint, it is not inherently secure. To understand why, we must first look at the history of TCP/IP. TCP/IP was designed more than 30 […]
