Abstract

The research paper covers two important topics to explain the crucial problems confronted by the web security. We will emphasize on providing all the latest developments in phenomenon of internet security, with respect to the chosen topics. The two topics, covered in this research paper are listed below:

JavaScript and Flash Pose a Serious Threat to System Security

End-point to End-point Encryption is the Ultimate Solution to Insecurity in IT Systems

JavaScript and Flash Pose a Serious Threat to System Security

In order to understand JavaScript, it must not be related to Java computer programming language, and JavaScript and Java must not be confused with one another. Java, computer programming language is a scripting language generally employed to enable programmatic approach to computational classes inside a server set-up; Java is most frequently employed for client-side web development. Whereas JavaScript programming code is employed to dynamically update the stuff of differently client stable web pages. On the other hand, Flash is a platform of multimedia system employed to append motion, video, and interactivity to web pages. Flash controls art components to furnish motion of textual matter, drafting's, and motionless pictures. It abides bidirectional flowing of audio and video, and it can catch user stimulation thru computer mouse, keyboard, microphone, and camera (Wikipedia, 2011). The scripting language of Flash is known as ActionScript.

With reference to the statistics of Adobe (developers of Flash Player), It has accomplished market penetration level of ninety-eight percent. This landmark was achieved couple of years back in March, 2010. Whereas eighty-five percent of the most-visited internet sites employed it and ninety-eight percent of organisations trust on Flash. On the other hand, JavaScript has achieved an incursion range of ninety-five percent during the year 2008 and the remaining five percent lacking was vanished in the succeeding years with Smartphone web browsers acquiring a come forward in their capacities (W3Schools, 2011). Although both JavaScript and Flash are anticipated a brilliant hereafter, they are endangered by severe protection issues.

Foremost, the security system computer architecture of JavaScript and Flash are dominated by the “Same Origin Guidelines”. This guideline entails that: “a script can interpret just the attributes of windows and manuscripts that have the equivalent beginning as the manuscript that comprises the script. Put differently, if a script just has the right to approach the attributes of the identical manuscript where it was engrafted and accordingly, the script can't interpret the content of additional manuscripts, accepted stimulations or broadcast commands to outside application programs. This, on paper, targets to forbids hackers to engraft script computer code into a web page so known as “Bad.html” that interact with contents and commands of a real web application program render “Good.html”.

Nevertheless, as scripting languages, consequently JavaScript and ActiveScript computer code isn't accumulated, it's immediately rendered on the zip by the application program on which they're employed. Both JavaScript and Flash permit application content to be engrafted in differently motionless internet pages and that content is auctioned on the end-user information processing ...
