Multi-level Parsing Based Approach against Phishing Attacks with the Help of Knowledge Bases

The increasing use of internet all over the world, be it in households or in corporate firms, has led to an unprecedented rise in cyber-crimes. Amongst these the major chunk consists of Internet attacks which are the most popular and common attacks are carried over the internet. Generally phishing attacks, SSL attacks and some other hacking attacks are kept into this category. Security against these attacks is the major issue of internet security in today’s scenario where internet has very deep penetration. Internet has no doubt made our lives very convenient. It has provided many facilities to us at penny’s cost. For instance it has made communication lightning fast and that too at a very cheap cost. But internet can pose added threats for those users who are not well versed in the ways of internet and unaware of the security risks attached with it. Phishing Attacks, Nigerian Scam, Spam attacks, SSL attacks and other hacking attacks are some of the most common and recent attacks to compromise the privacy of the internet users. Many a times if the user isn’t careful, then these attacks are able to steal the confidential information of user (or unauthorized access). Generally these attacks are carried out with the help of social networking sites, popular mail server sites, online chatting sites etc. Nowadays, Facebook.com, gmail.com, orkut.com and many other social networking sites are facing these security attack problems. This paper discusses a Knowledge Base Compound approach which is based on query operations and parsing techniques to counter these internet attacks using the web browser itself. In this approach we propose to analyze the web URLs before visiting the actual site, so as to provide security against web attacks mentioned above. This approach employs various parsing operations and query processing which use many techniques to detect the phishing attacks as well as other web attacks. The aforementioned approach is completely based on operation through the browser and hence only affects the speed of browsing. This approach also includes Crawling operation to detect the URL details to further enhance the precision of detection of a compromised site. Using the proposed methodology, a new browser can easily detects the phishing attacks, SSL attacks, and other hacking attacks. With the use of this browser approach, we can easily achieve 96.94% security against phishing as well as other web based attacks.
