If an applicant said they were comfortable with setting up an Exchange server, but later confessed that “I haven’t really sent too many emails.”, you’d throw their resume in the trash and douse it with a strongest acid that HR allows in the workplace. If you were interviewing a Sysadmin for a job setting up a new Windows Domain Server and some file servers and they said: “You know, I haven’t really worked with files before”, you’d throw their resume in the trash. But in order to understand injection/vulnerabilities, we need to take a step back and review that basic SQL knowledge first, which you may not have needed until this point in your role as a sysadmin. We’re going to get to work our way up to SQL injection attacks and the reason they are scarier than a clown who lives in a drainpipe. Loads of SQL queries will be coursing through your web applications on almost every page load – regardless of if it’s a tiny toy website with a tiny SQLite file, or a popular ecommerce site with millions of visits per hour requiring a massive cluster of database servers from Enterprise Database Vendor of choice.Īnd so, armed with literally nothing but a web browser, some basic SQL knowledge and an internet connection, an attacker can exploit flaws in your web application – extracting user data, discovering or resetting credentials and using it as a launch point for deeper assaults on your network. Standardized query language (SQL) is, in one form or another, still the dominant method of inserting, filtering and retrieving information from a database. For instance, you can often grind a database and web server to a halt simply by requesting all of the records in the database instead of the 1 record that the application page would typically load. Will quite likely crash if you run even an “innocuous” SQL injection attack against them.Were developed a decade or more ago when some security development practices weren’t as ingrained.Are presumed to be internal, so security isn’t a big priority.In particular, if you’re a sysadmin in any moderately sized organization, there are probably a half dozen internal applications that your company depends upon day in and day out which: Please approach practical aspects of this with the same seriousness as you would the new IT staff member telling you: “It’s just one command, how much damage could it possibly do?” Which is why we’re taking this point in time to point out that SQL Injection attacks are one of those situations where the outcome can be wildly disproportionate to the amount of effort that went into executing it. “This really opened my eyes to AD security in a way defensive work never did.” Featured Webinar DatAlert Master Class On Demand Watch Now.Get a Personalized Varonis Demo (In-Person or Online) Schedule Now.Data Classification Engine Sensitive Data Discovery.Data Security Platform Product Suite Overview.
