It also keeps tabs on file and USB integrity and can stop data download or access if something doesn’t look right. As a result, you can minimize time delays if there’s an attack on your system. SolarWinds SEM can be set up to automatically respond to suspicious IP addresses or shut down applications behaving strangely (suddenly producing a lot of errors). Making sure you quickly respond to a SQL injection is extremely important, because attackers can access vital and confidential data fast. SolarWinds ® Security Event Manager (SEM) is my top choice for keeping an eye on how your network is behaving and flagging issues like a SQL injection. Choose one of the following tools to get started with protecting your network against SQL injection attack.īack to top Best SQL Injection Prevention Tools Make sure you have set up access alerts and anomaly detection.
Next, you can also use tools or software to keep an eye on your system security, so if a vulnerability has gone undetected, the tool will pick up on any issue. Then, review your existing codebase to check for vulnerabilities. Make sure you subscribe to updates from security communities so you’re aware of any new issues.
SQL injection vulnerabilities can also be discovered in old code previously assumed to be safe. No matter how well you write your code in the first place, new vulnerabilities can arise whenever code is added or changed. With good coding practices and code quality tools, you can detect user input and interfaces which expose too much surface area to attack. The first technique to prevent SQL injection is to make sure your application is designed to reduce the surface area through which an attacker can inject code. Preventing SQL injection can be achieved at several points along your system pathway.
This can only occur if particular features are enabled on the SQL database.
Out-of-band: Out-of-band SQL attacks aren’t common, as they use two different channels to send the attack and then receive the results. For example, it may send a SQL query asking for a time response that either responds immediately or with a delay, depending on if the query to the SQL database returns “true” or “false.” They don’t transfer data through the web application but instead send payloads to the database server to look at how it responds and use the resulting information to infer information about the database. Inferential: Inferential SQL injections, also known as Blind SQL injections, generally take longer to carry out. Union-based SQL injection exploits a vulnerability in the way SQL is written, by using the “UNION” operator to get the database to return more information than should be accessed. Errors are useful when developing the database and for network administrators, but only certain errors and information should be displayed on a live web application. Error-based SQL injections trigger the system into producing errors, building up a picture of what the database looks like. There are two main types of in-band attack, called error-based and union-based SQL injection. In-band: This classic type of SQL injection describes an attack in which the attacker uses the same channel to both inject the attack and obtain their desired data results. There are a few different SQL injection types, including: If an attacker manages to access data and impersonate a database administrator, they can then access the entire system using those copied credentials. Usually the purpose of this code is to access data to steal it (like user credentials) or delete it (to harm a business). SQL injection is when malicious code is inserted as user input, so once it gets into the system and is turned into a SQL query, it begins to execute the malicious code. When a part of a website or application allows a user to input information turned directly into a SQL query, this makes the website vulnerable to SQL injection. It’s primarily used to access, add, modify, and delete data from these databases. SQL is a programming language designed to manage large amounts of data stored in a database. How Tools Help Prevent SQL Injection Attacks SQL Injection Definition I’ll also review the best tools to help protect against SQL injection attacks available on the market today. In this guide, I’ll explain the two key questions you must understand when working to prevent or resolve SQL injection. Understanding how SQL injection works is vital information for application and web developers, as well as network and security professionals who may end up dealing with the repercussions of a poorly developed website. When this kind of input data is directly turned into a SQL query, the program or website allowing the input can be vulnerable to malicious code. Websites and applications all need to interact with their users, which means users must have some way to input data, whether it’s a text box on a website or a web form within an application.
