How can you teach your team to prevent SQL injection attacks?

SQL injection is a form of attack wherein an adversary can gain full control of the web application database by inserting unauthorized SQL code into database query.

SQL injection is a very common attack that allows accessing the content of a database to query, modify or delete data. To carry out the attack, SQL statements are maliciously executed in the database (usually in web forms). With this, the attacker might be able to obtain confidential data or even end up gaining remote access to the system.

SQL injection is a type of attacking mechanism in which attackers utilize malicious SQL queries to cause damage to your backend databases - which can include (but not limited to) altering specific data in your databases to even dropping your entire database.

SQL injection is a type of cyber attack where malicious SQL code is inserted into input fields or data parameters, exploiting vulnerabilities in a web application's database layer. This unauthorised SQL code can manipulate the database, potentially leading to data breaches, unauthorised access, or other security compromises.

SQL injection is a potential vulnerability of application data access layer. It allows a malicious user bypass security by executing arbitrary SQL query. Many dangerous actions can be performed in that way like: - unauthorized data modification - access to protected information like user passwords, credit cards

Many programmers assume these attacks do not apply to NoSQL DB’a but queries can be manipulated, for example: `username: { “$gte”: “” }` to list all users in the DB.

SQL injection attacks take advantage of weak security practices in web applications. When an application doesn't thoroughly check and sanitize user inputs before using them in SQL queries, it creates a vulnerability. For example, in a login form, if the application blindly includes user inputs in a SQL query, an attacker can manipulate it. ex: SELECT * FROM users WHERE username = '<username>' AND password = '<password>'; If the application doesn't properly check the user inputs, an attacker can input something like: ' OR '1'='1' -- The manipulated query becomes: SELECT * FROM users WHERE username = '' OR '1'='1' --' AND password = '<password>'; Here, '1'='1' is always true, allowing the attacker to log in without a valid password.

Clean up, validate prompts. No. Limit to exploits when a programmer spends 30 minutes writing the function and stands defeated by an unlimited time someone else spends tricking it out. How can I show my team? Simply sharing the vulnerabilities to them, since communications with any team is as important as their skills with writing code to be a success. Teams are no good when they cannot speak with each other.

SQL injection works by exploiting poorly sanitized user inputs in a website's forms or URL parameters. Attackers inject malicious SQL code into these inputs, tricking the application into executing unintended database commands. This can lead to unauthorized access, data manipulation, or other malicious actions within the database. Imagine a login form where you enter your username and password. If the website doesn't properly validate inputs, an attacker could input something like: Username: `admin'; DROP TABLE users; --` If the application doesn't handle inputs securely, it might construct a SQL query like: SELECT * FROM users WHERE username = 'admin'; DROP TABLE users; --' AND password = 'some_password'; This will cause several issues

Attackers manipulate SQL queries through insecurely handled user input in an application. In this attack, specially crafted input alters a database query's intention, potentially leading to unauthorized access, data theft, or destruction. For example, in a login form, instead of entering a username, an attacker inputs an SQL fragment that changes the query logic, bypassing security checks. This vulnerability underscores the importance of validating and sanitizing user inputs and using secure coding practices like prepared statements in database interactions. SQL injection poses a severe risk to data integrity, making awareness and prevention crucial in application development and database management.

Use Parameterised Queries or Prepared Statements: Used parameterised queries or prepared statements in your database interactions. This practice ensures that user input is treated as data, preventing malicious SQL injection by separating it from the actual SQL code.

Common ways to prevent SQL injection include the following: 1. Parameterized queries 2. Input sanitization 3. Input validation

- Use prepared statements and parameterized queries. - Validate and sanitize user inputs. - Employ stored procedures. - Implement least privilege access for database accounts. - Keep software and databases updated. - Use custom error messages for security. - Deploy a Web Application Firewall (WAF). - Conduct regular security testing and code reviews. - Educate developers about secure coding practices.

Usually we focus on asking developers of taking care of this by writing "clean" code/queries and data sanitization in order to avoid SQL injection. This is of course best practice but you don't have always the application developer at hand (or you might be running a legacy app but still mission critical for the company). On a system/infra level, you can help avoiding this by: - implementing least privilege database access and in general limit access to the database; - perform regular maintenance including applying of security patches on the database engine. - monitor your database and database engines. - deploy a WAF in front of the web app. - perform (black- or greybox) pentesting to reveal vulnerabilites and patch them.

To help prevent SQL injection, I advise to always use parameterized queries and prepared statements but ALSO validate your input to these queries. The best way to teach the team this is through a culture of looking for these types of issues, constantly asking ourselves where our data is coming from and making sure to use validation tools specialized where possible.

Le plus simple pour éviter les injections, c'est d'arrêter de créer les requêtes SQL à la main. La plupart des QueryBuilders et des ORM te protégeront automatiquement. Si tu n'as pas le choix, pense à vérifier les types de tes variables et à échapper les cha?nes de caractères.

The worst thing you can do as an engineer when you write applications is to hardcode SQL code within business logic manually, this will eventually blow up, as most hackers will try to abuse every page and every input to take advantage of your "lousy" SQL code and mold it for a behavior to their advantage, most of the time circumventing your security protocols and controls.

There are many ways to teach your team how to prevent SQL injection attacks. Here are some possible methods: You can enroll your team in an online course that covers the basics of SQL injection, its exploitation and its mitigation. You can conduct a workshop or a seminar for your team where you demonstrate how SQL injection works, how to find and exploit SQL injection vulnerabilities, and how to defend against them. You can create a checklist for your team that summarizes the best practices for preventing SQL injection attacks. You can organize a competition for your team where they have to find and exploit SQL injection vulnerabilities in a given application or website.

Create an "Escape Room" challenge themed around SQL injection for your developer team. This engaging, hands-on activity simulates a real-world scenario where they must "escape" by identifying and fixing SQL injection vulnerabilities in a sample application. Provide clues and puzzles that lead to understanding the importance of parameterized queries, prepared statements, and input validation. Incorporate tools and frameworks for practical learning. Conclude with a debrief session to reinforce best practices and promote a security-first mindset. This creative approach makes learning about SQL injection prevention both memorable and effective.

Ne pas réinventer la roue. Il existe beaucoup de librairies qui font cela très bien comme Doctrine ORM ou yii.activeRecord ou équivalents. L’important est d’utiliser le paramater binding. Les mêmes framework proposes des fonctionnalités de ??Sanitization?? pour netoyer les données saisies dans les formulaires. Tout cela vise à ne jamais fabriquer une requête sql en concatenant un bout de commande sql avec des données venants de formulaires ou des paramètres get.

Hackedu has a great securities training program going in depth with multiple user friendly learning modules on how to prevent SQL injections and command line injections. The program is set up to teach the individual in how to read SQL injections and find vulnerabilities within your code.

**Online Courses and Tutorials:** **Security Websites and Blogs:** - Follow security-focused websites and blogs such as OWASP (Open Web Application Security Project) for in-depth articles and resources on SQL injection. **Practice on Vulnerable Platforms:** **Books on Web Security:** **Security Forums:** **CTF (Capture The Flag) Challenges:** **Security Conferences and Webinars:** **Security Certifications:** - Consider pursuing certifications like Certified Ethical Hacker (CEH) or Offensive Security Certified Professional (OSCP), which cover SQL injection as part of the curriculum.

Investigate online tutorials and courses on sites like Codecademy and Udemy that provide thorough teachings on SQL and web security to enhance your comprehension of SQL injection. Consult the official documentation of widely used databases such as PostgreSQL and MySQL to gain knowledge about security best practices, which include preventing SQL injection. For practical insights, read security blogs and forums, and go to conferences like DEF CON. In addition, look into getting security certifications such as OSCP or CEH, and search open-source web security and SQL injection projects on GitHub.

If you’re quick at picking up knowledge, there are the official practice CTF (capture the flag) challenges like HTB and OWASP mentioned above, and there are unofficial ones that aren’t designed to make the owner money. You can find these unofficial ones if you’re resourceful. They’re mostly hosted on Russian & Ukrainian servers. While Americans want people to pay for college, but other countries, in particular the two above, want people to increase their knowledge. You have to be careful, as they might be honeypots, so always try to do any pentesting in a virtual machine or separate OS. And there are classes, both free and paid, such as on LinkedIn Learning, MIT OCW, and all the cybersecurity master’s degrees offered by reputable schools.
