5 Error Handling Errors and error handling represent a class of API, but problems related to error handling are so common that they deserve a kingdom of their own As with API abuse, there are two ways to introduce an errorrelated security vulnerability The rst (and most common) is to handle errors poorly or not at all The second is to produce errors that either reveal too much or are dif cult to handle safely 8, Errors and Exceptions, focuses on the way error handling mishaps create ideal conditions for security problems 6 Code Quality Poor code quality leads to unpredictable behavior From a user s perspective, this often manifests itself as poor usability For an attacker, it provides an opportunity to stress the system in unexpected ways Dereferencing a null pointer or entering an infinite loop could enable a denial-of-service attack, but it could also create the conditions necessary for an attacker to take advantage of some poorly thought-out error handling code Good software security and good code quality are inexorably intertwined 7 Encapsulation Encapsulation is about drawing strong boundaries In a Web browser, that might mean ensuring that your mobile code cannot be abused by other mobile code On the server, it might mean differentiation between validated data and unvalidated data (see the discussion of trust boundaries in 5), between one user s data and another s (privacy, discussed in 11), or between data that users are allowed to see and data that they are not (privilege, discussed in 12) * Environment This kingdom includes everything that is outside the source code but is still critical to the security of the product being created Because the issues covered by this kingdom are not directly related to source code, we have separated it from the rest of the kingdoms The con guration les that govern the program s behavior and the compiler ags used to build the program are two examples of the environment in uencing software security Con guration comes up in our discussion of Web applications ( 9) and Web Services ( 10)

Getting security right requires understanding what can go wrong By looking at a multitude of past security problems, we know that small coding errors can have a big impact on security Often these problems are not related to any security feature, and there is no way to solve them by adding

or altering security features Techniques such as defensive programming that are aimed at creating more reliable software don t solve the security problem, and neither does more extensive software testing or penetration testing Achieving good software security requires taking security into account throughout the software development lifecycle Different security methodologies emphasize different process steps, but all methodologies agree on one point: Developers need to examine source code to identify security-relevant defects Static analysis can help identify problems that are visible in the code Although just about any variety of mistake has the theoretical potential to cause a security problem, the kinds of errors that really do lead to security problems cluster around a small number of subjects We refer to these subjects as the Seven Pernicious Kingdoms We use terminology from the Seven Pernicious Kingdoms throughout the book to describe errors that lead to security problems
