variable-based and stain analysis, as well as a good response to various flexible syntax representations in PHP scripts, and the approach I've introduced is based on the auditing of code static analysis techniques and data flow analysis techniques.First, I think an effective audit tool contains at least the following modules:1. Compile the front-end moduleThe compiler front-end module mainly uses the abstract syntax tree construction, the control flo

In addition, code review is performed for each webpage sentence. Because the webpage code is huge, it cannot be analyzed manually or completely eliminated. From a realistic perspective, many schools have stipulated that network administrators must perform manual review. However, due to the above reasons, web page aud
Code auditing at Party A's company is generally dominated by white boxes, with only a few vulnerabilities, XSS, SQL injection, command execution, upload vulnerability, local inclusion, remote inclusion, Permission Bypass, and information leakage.

XSS and SQL Injection occupy the largest part of the data. For framework types or public files, we recommend that you filter XSS and SQL Injection in public files. Write a filter functi

Google does not seem to be able to find any article that uses open-source software to implement online behavior auditing-it is no wonder that open-source is not popular in China, and online behavior auditing is not popular abroad. However, this does not mean that it cannot be implemented. IS in Public provides an idea and method to use open source sniffing tools and scripts to implement

Create an audit policy at the CDB, PDB level4. The audit strategy will not take effect until it is allowed. Standard non-policy audits are not affected by enable/disable5. Create an audit policy you must specify the audit options at the system level or at the object level-System level:Privi
Audit is the monitoring and recording of selected user actions. It is usually used:
U reviews suspicious activities. For example, if the data is deleted by an unauthorized user, the security administrator may decide to audit all connections to the database, and audit the deletion of all tables in the database.
U monitors and collects data about specified database activities. For example, DBA can collect statistics on the modified and executed logic.
Oracle supports three audit types:

So let's talk about code audit, this time we use dvwa.DVWA (Damn Vulnerable Web Application) DVWAIt is a set of WEB vulnerability testing programs written in PHP + Mysql for teaching and detecting general WEB vulnerabilities. Includes SQL injection, XSS, blind injection, and other common security vulnerabilities.The following is a simple example of code
