Very often, secure applications come at the expense of complexity (and developer headaches). The Tornado web server has been designed with a number of security considerations in mind, making it easy to protect against a few well-documented vulnerabilities. Secure cookies prevent a users local state from being surreptitiously modified by malicious code in his browser. Additionally, browser cookies can be compared with HTTP request parameter values to prevent cross-site request forgery attacks. In this chapter, we will look at features in Tornado that make preventing these attacks easy and then look at a user authentication example that uses these features.
Many websites use browser cookies to store a users identity between browser sessions. Its a simple and widely compatible way to store persistent state across browser sessions. Unfortunately, browser cookies are susceptible to a number of well-documented attacks. This section will demonstrate how Tornado prevents a malicious script from tampering with your applications stored cookies.See All Chapters

This book is a part of Perl culture, so we can't hope to put everything we know about Perl culture in here. We can only whet your appetite with a little history, and a little art--some would say "very little art". For a much larger dose of Perl culture, see http://www.perl.org and http://www.perl.com. (Larry keeps copies of all his (official) ravings at http://www.wall.org/~larry.) Or just get acquainted with some other Perl programmers. We can't tell you what sort of people they'll beabout the only personality trait Perl programmers have in common is that they're all pathologically helpful.
In order to understand why Perl is defined the way it is (or isn't), one must first understand why Perl even exists. So, let's drag out the old dusty history book....
Way back in 1986, Larry was a systems programmer on a project developing multi-level-secure wide-area networks. He was in charge of an installation consisting of three VAXen and three Suns on the West Coast, connected over an encrypted, 1200-baud serial line to a similar configuration on the East Coast. Since Larry's primary job was support (he wasn't a programmer on the project, just the system guru), he was able to exploit his three virtues (laziness, impatience, and hubris) to develop and enhance all sorts of useful tools--such as rn, patch, and warp.See All Chapters

The gang saves Mystic Falls from the Travelers. The Other Side collapses.
And so it ends. Season five closes with a heartbreaking implosion (and an impressive explosion) that leaves our characters unmoored — some loved ones lost, others returned. Home is where the heart is, as the saying goes, and in this finale, the Mystic Falls gang proves willing to go to the ends of the earth to be together and to protect each other, even when that means risking not only their lives but their eternal existence.See All Chapters

Root Cause Map™ Guidance
E.1 Instructions for Using This Appendix with the Root Cause
E.1.1 Types of Information Provided
This appendix provides detailed information about the use of ABS Consulting’s Root Cause Map™ (which can be found in Appendix F of this handbook). A larger color version is also inserted in the handbook.
Using the Root Cause Map™ will assist the investigator in identifying additional root causes and trending root causes.
The Root Cause Map™ has many shapes, which are generically referred to as nodes. For each node, general information is provided under the heading of “Definition/Typical Issues.” “Definition/Typical Issues” can help the investigator distinguish between similar items on the map and appropriately code each root cause.
Figure E.1 shows a sample section of the Root Cause Map™ and its nodes.
