Abstract:

Lots of business application systems operate to do remote data transmission using files with formatted contents, which are business data. After a detailed analysis of security threats suffered by such an application system, this paper introduces a content inspection technique for files with formatted contents, and designs and realizes FFCCIS(A Content Inspection System for Files with Formatted Contents),which matches file contents with formatted templates in the form of regex expression to inspect tempered or invalid files. An automatic method for generating the content formatted templates is put forward to make the templates write more conveniently and efficaciously.

Key words: regex expression;approximate string matching;files with formatted contents;automatic generating templates;scalable
