A code inspection tool comprises a plurality of physical computing resources connected by a network facility, eg an LAN, intranet or internet, and a voice conferencing communications facility. The code inspection tool interfaces with a known configuration management system to load a quantity of original source code. A group of developers use a plurality of graphical user interfaces to inspect the code. All graphical user interfaces log into display views generated on a main graphical user interface, which is operated by a human controller of a code inspection session. The code inspection tool comprises means for allowing developers to compile annotation data and forward the annotation data from their respective graphical user interfaces to a centralized data store. Internal algorithms of the code inspection tool compile markers relating the annotation data files to individual lines of source code. During a code inspection session, all developers view a same display, which sets out original source code, side by side with new source code on a line by line basis, matching the line numbers of the original source code with those of the new source code. Changes to the original source code and new source code are visually identified by automatic generation of icons next to the appropriate source code lines on the display. Annotations to the source code lines are indicated by further icons next to the appropriate lines. The tool automatically generates data describing statistics of a code inspection process, for example number of lines inspected, during of a code inspection session, proportion of original and new code lines inspected. Code inspection reports may be generated in a variety of formats, eg plain text or HTML, and automatically distributed to individual developers over the networked facility.

Software developers previously dealt with each security threat by incorporating a corresponding set of code lines into individual web applications, which required significant amount of time and code lines for each security threat and the resulting code was hard to maintain or modify. One aspect of the present invention addresses common security concerns in a standardized and centralized approach. All user requests for web applications are centralized to a single input and validated by a Web Security Filter. Selected layers of validation filters (e.g., ESAPI and AntiSamy) could be sequentially applied to the user requests, and those filters can be individually maintained / modified as discrete modules. Not only is this centralized, holistic approach to application security effective against a majority of malicious attacks, it is also saves a lot of time and costs in code development and maintenance.

The first code lines are Gray codes including third code lines that do not appear the same even when a digit from which they are read is changed and fourth code lines that appear the same when a digit from which they are read is changed. The first code lines at adjacent steps and the first code lines at the first and last steps differ from each other at one bit. Each first code line is shifted by one digit at every predetermined number of steps, and the first code line without shift is obtained when the first code line corresponding to the maximum shift is further shifted by one digit. The second code lines identify the fourth code lines.

A novel system and method provides a concrete relative measure for evaluating coding quality. The novel system and method do not rely on bug counting. Instead, the number of defective lines of code is compared to a total number of opportunities to create such defects. A defective line is a line that is deleted, added or changed subsequent to drafting of the prior version of the code. In an embodiment, a deletion and an addition are each treated as single defects, while modification of a line of code is treated as two defects. In this way, regardless of whether modification is viewed as deletion followed by addition, or rather simply a single step of modification, the number of defects in either case is the same.
