Preserving integrity

摘要

With the attention security problems are getting these days, we're finding that our clients are increasingly interested in the details of the online systems we build for them. A number of security issues can affect applications written in languages like Perl, Python, and Tcl. Scripting languages have a few important things in common. Because they're higher-level languages and don't provide the kinds of low-level manipulation that C does, they're not vulnerable to many of the same types of attacks. Yet, because many compilers and interpreters for scripting languages are implemented in C, a bug in the underlying implementation could possibly expose you to attack. But simple research on the vulnerabilities floating around will show you that these problems are rare, if not unheard of.
