How Simple can it be.....XSS Prevention....

Cross Site Scripting is sill a very common web vulnerability. Generally it is used to attack clients/users. It can be used for malware upload, botnet hooking, keylogging, a payload delivery system for clickjacking and CSRF attacks and much much more, all for 6 easy payments of $9.99...sorry got carried away there :) But is is easily preventable. You dont even have to know what XSS (type 0, type 1, type 2, DOM, Stored, Reflected) is to prevent it. One pretty simple way to prevent XSS is to use the OWASP ESAPI (Enterprise Security API). A very easy tool to use/invoke. It's also managed and attended to by Chris Schmidt ....A great guy... Regardless of what it does....if there was a mandate to use it on all redisplayed external input a site could become virtually XSS free!! (all for 6 easy payments of......). It's easy to deploy.... 1. Include in JSP (Java version) 2. Invoke in JSP 3. Job done!!! We include it by <%@ page import="org.owasp.esapi.ESAPI...

"Are we secure?...." A major issue with enterprises is "are we secure?" (what does that even mean...). If you are asked by the CEO whilst sharing a lift to the 10th floor,what do you answer??? eh..em yes..er no...well sort-of..... A few important aspects in attempting to figure out "Are we secure?" from an web security standpoint are (1) How do we make sure the security of our current public facing Internet web landscape is *pretty* robust (not 100% secure)? - Test, maintain, patch, measure, observe..... (2) So how do we make sure systems in design/development are not going to introduce new risk to your business? - Security: Design, Dev,Test, Review, Deploy, Maintain, Patch. ..........So how do we track ongoing assurance efforts, prioritization of technical issues, appoint appropriate risk, track remediation, identify root cause, technology adoption weakness, mixed with securing new deployments (1) & (2) above? - Excel Spreadsheets, Memor...

Website Insecurity: This grinds my gears....

This document reflects my personal opinion on the state of application security. It calls out what I see are the weaknesses of our approach as a community to addressing the issue of web [in]security. Web [in]security is a healthy and growing industry and rather than verification of issues we constantly find and are exposed to new threats without every addressing the current ones en-masse…….   A long ,long time ago we used to “ test security out ” when it came to web applications. This meant performing a time limited penetration test on a web application in the hope you could find all the existing vulnerabilities using the skills, resources and tools at your disposal….Oh, actually we still do this.. There are weaknesses to this approach and can be reflected in the current state of internet, application, cyber security. To be honest the issue of web [in]security is getting worse. Despite growth in the security industry (solutions, vendors, consultants) and the fact th...
