However, if your monitoring tool uses extended events, it can detect errors characteristic of a SQL Injection attack, and which otherwise should be very infrequent in a well-tested production system.
The hacker relies on the fact that these errors aren’t usually detected by monitoring systems, and some of them aren’t even logged, so scanning the error logs won’t help.

In the early stages of an attack, this is usually done by trial and error, deliberately triggering SQL errors as they attempt to navigate the schema. To do more than that, they will need to bypass any interface, and even attempt to escalate the privileges of the login, to get to any other data. Once the attacker has a connection that can be exploited, such as a website HTTP connection, they will need to assess what permissions they have and what data is available. In fact, the error messages are usually the main vector that the attacker uses to get information. This is, of course, essential for a post-mortem examination, but is less useful for warning you that an attack is taking place.Īttacks are usually messy and potentially visible because they involve trial and error by the hacker in the information-gathering stage.

It detects, for example, all password changes, backups and restores, logins, logouts, database operations, permission changes and ownership changes. This includes recording data manipulation language (DML) and Data Definition Language (DDL) operations. SQL Server Audit provides a very effective general-purpose audit mechanism and is ideal for tracking the damage a successful penetration has wreaked. At that time, the main objective the attackers had was to take control of the server, but nowadays their focus is more on data. Never again have I taken database security lightly. The websites were attacked routinely with automated tests, and sometimes by a live hacker, that carefully tested for all the common vulnerabilities. The laugh happened so often that the programmers eventually complained. They were set to play the sound of Vincent Price uttering a demoniacal laugh whenever an attack was attempted. I installed on them both intrusion-detection systems, to detects attempts to gain illegal access to the network, and attack-detection systems, to detect when servers were being probed for signs of weakness. I once worked for a company whose business was to ‘incubate’ startups, and we regularly launched websites. You will be surprised how often a public-facing website is attacked.
How can you detect when an attack is taking place? I’m not suggesting it is a complete system you’ll expand and evolve the solution in the face of changing methods of attack.

In this article, I’ll be showing how to make a start with monitoring a database to alert you to a possible SQL Injection attack, or any obvious attempt to gain illicit access to a database server. It is important, though, to also provide an alert when, despite all precaution and defences, the database is being attacked. This will make sure that your application and database can successfully resist an attack. It has become increasingly common to add a penetration test to the set of tests that are performed on a release candidate of a database application, to check that all the obvious attack vectors are well tied-down, and to ensure that the database can detect attempts at penetration. There are several strategies for detecting SQL Injection attacks, and other attempts at penetrating a SQL Server database. He is a regular contributor to Simple Talk and SQLServerCentral.Įven if all precautions have been taken to prevent SQL Injection attacks, as laid out in the OWASP website, it is still wise to be able to detect if an attempted attack is taking place, and it is essential to know if such an attack is successful.
