How to Tighten Web Browser Security

Author : Admin

There are several step, we as client or users can take to make web browsers and e-mail client more secure and protect against malicious code or unauthorized use of information. In this discussion, we will describe step by step how to tighten the security of web browser in general browsers or client, it’s not specific in one of the browsers.


First step to make sure our browser more secure is restricting the use of programming languages. Most web browsers have option settings that allow users to restrict or deny the use of web based programming languages. For example, Internet Explorer can be set to do one of three things when a JavaScript, Java or Activex element appears on a web page : Always allow, Always Deny and Prompt for user input.


Restricting all executable code from Web sites, or at least forcing the user to make choices each time code is downloaded, reduces security breaches caused by malicious downloaded components.


A side benefit of restricting the Web browser’s use of these programming languages is that the restrictions set in the browser often apply to the e-mail client as well. This is true when the browser is IE and the e-mail client is Outlook or Outlook Express, and Netscape and Eudora also depend on the Web browser settings for HTML handling. The same malicious code that can be downloaded from a Web site could just as easily be sent to a person’s e-mail account. If administrators do not have such restrictions in place, their e-mail client can automatically execute downloaded code.


Second step to tighten web browser security is aware of the function of cookies. Cookies are a general mechanism that can use to store and retrieve information on the client. It’s a small text file stored on our hard drive by a web server and essentially as our identification, uniquely and can only be read by the server that gave it. A web server put it more plainly, allow a web site to record our comings and goings without our knowledge or consent.


If a web site uses cookies for authentication, then an attacker may be able to acquire unauthorized access to that site by obtaining the cookie. Persistent cookies pose a higher risk than session cookies because they remain on the computer longer. So, it’s very dangerous if there are attacker who can use our cookies.


Third step to make sure our web browser secure is keep security patches current. It is important to understand the functionality and features of the web browser we use. Enabling some web browser features may lower security. Often, vendors will enable features by default to improve the computing experience, but these features may end up increasing the risk to the computer.


There are bugs that can cause any number of issues when using the program. In some case and conditions, with this issue hacker being able to remote control our computer. For this reason, it’s better to have the software on shelves, bugs and all, and then release patches later to fix the problems. Patches are often released quickly, in response to an immediate problem or security vulnerabilities.
