Personally identifiable information (PII) is information regarding things such as bank accounts, retirement or stock investment accounts, credit card accounts, medical records, or insurance claims. There is a need to protect the PII in databases that are connected to the ubiquitous, global network that is the Internet. If there is any vulnerability in the protection in a system that holds PII, then it presents an opportunity for an unauthorized person to access this PII. One of the techniques available to would- be information thieves is SQL injection (SQL-I). In this project, a system is developed to analyze the values submitted by users through HTML forms and look for possible attack patterns. Once the system finds such a pattern, it blocks the attack and makes a record of the activity. If an attacker continues to pass such attack patterns, the system blocks access by this user altogether. A mechanism is included to block users who attempt to log in at an abnormally high rate. This provides a combination of pattern-based detection and anomaly-based detection to create a reasonably robust intrusion detection system, with respect to SQL-I attacks.
