Hunting missing checks with anomaly detection

In our previous article we focused on taint-style vulnerabilites, i.e., those that are essentially due to the lack of input sanitization which allows tainted, user-controlled data to reach sensitive functions. Some of these arise due to missing checks in code, such as: failure to check authentication, authorization...

Mining graph representations for vulnerabilities

As we have seen in our previous revision article, probably the most interesting and successful approach to automated vulnerability detection is the pattern-based approach. Since we expect to extract meaningful patterns from the code we also need a "comprehensive and feature rich representation"[1] of it. Other...

Machine learning for vulnerability discovery

To date the most important security vulnerabilities have been found via laborius code auditing. Also, this is the only way vulnerabilities can be found and fixed during development. However, as software production rates increase, so does the need for a reliable, automated method for checking or classifiying this code in …
