Setting up SSL on Tomcat is easy and you don’t have to do much for converting your web application to work with the Https protocol. But however, the problem you would find to set up SSL is the documentation available over the web. The documentation source is available on the Apache site but it starts off good and ends with a lot of confusion. Especially I was confused on the OpenSSL part where it says to use OpenSSL.
It might be good in a production environment to use OpenSSL but if you just want to test out SSL with Tomcat alone then it is more than enough to just have your JDK and Tomcat setups. The things which I have used to setup SSL consists of: JDK 1.6Tomcat 6 Even though I have used the latest version I don’t see any problems which you might face in carrying out the same set of steps for JDK 1.5 which I am about to explain. Generating the Keystore fileConfiguring Tomcat for using the Keystore fileConfiguring your web application to work with SSL Let’s get this party started now. 1. Understanding JSSE. Although the JSSE guide provides detailed information on the JSSE API and its use in application programming, this article dives deeper into the different message exchanges involved when a programmatic Java client communicates with a server over the SSL.
It will help developers understand the fundamental but often overlooked JSSE concepts of keystore, truststore, cipher suites, certificates, and the public key infrastructure and help them solve some of the common programmatic and configuration issues that arise when developing Java clients that communicate over SSL. It enhances the JSSE guide documentation by walking the reader through a debug output and explaining each message exchange between a client and the server in detail. Before starting, it's important to note that JSSE is fundamentally different from the Java Authentication and Authorization Service (JAAS).
Secure Socket Layer One of the common uses of SSL is in Internet commerce. Cryptography Public Key Infrastructure. [the new p0f] Copyright (C) 2012 by Michal Zalewski <lcamtuf@coredump.cx> Yeah, it's back! 1. What's this? P0f is a tool that utilizes an array of sophisticated, purely passive traffic fingerprinting mechanisms to identify the players behind any incidental TCP/IP communications (often as little as a single normal SYN) without interfering in any way. Version 3 is a complete rewrite of the original codebase, incorporating a significant number of improvements to network-level fingerprinting, and introducing the ability to reason about application-level payloads (e.g., HTTP). Some of p0f's capabilities include: Highly scalable and extremely fast identification of the operating system and software on both endpoints of a vanilla TCP connection - especially in settings where NMap probes are blocked, too slow, unreliable, or would simply set off alarms.
You can read more about its design and operation in this document. Fun fact: The idea for p0f dates back to June 10, 2000. 2. 3. 4. 5. SmartSniff: Freeware Packet Sniffer - Capture TCP/IP packets on.

Versions History. Greg Murray's Blog: Preventing Cross Site Scripting Attacks. Posted by gmurray71 on September 27, 2006 at 12:01 PM PDT Cross site scripting (XSS) is basically using JavaScript to execute JavaScript from an unwanted domain in a page. Such scripts could expose any data in a page that is accessible by JavaScript including, cookies, form data, or content to a 3rd party.
Here is how you can prevent your web pages from being exploited on both the client and the server. This is followed with tips on how to avoid vulnerable sites. Escape parameters and User Input - The safest step you can take is to escape all parameters to a page where the parameters are displayed in the content.The same applies for any user input that may be displayed or re-displayed in a web page rendered by a server. Escape Parameters and User Input This is the classic XSS attack that can open your service or web application up to hackers. A request to the URL index.html?
