What steps would you take to prevent an SQL injection attack?
An SQL injection can be described when attackers use the input fields in web applications to run arbitrary queries on the server. Hackers will then use your input fields to inject malicious codes, then the server executes the code received from the browser. Once a hacker gains control, he can steal, edit, delete, sensitive data or exploit other administrative rights. Some ways we can prevent an SQL injection include:
Continuous Scanning and Penetration Testing.
Restricting Privileges.
Actively Manage Patches and Updates
Raise Virtual or Physical Firewalls
Harden Your OS and Applications
Reduce Your Attack Surface
What are advantages and disadvantages of dynamic SQL statements?
The advantage of using dynamic SQL statements is more flexibility in coding an application, flexibility for a user to find the information they want formatted the way they need, and expansion without adding more stored procedures. The drawback to an SQL statement is that using dynamic SQL statements requires the database application to generate the code then execute it as requested, which means it is processing more before it starts looking for results. It is then formatting the results on the fly as well, which further slows the application other drawbacks are security issues and potential errors.
What types of databases are more vulnerable to SQL injections?
SQLi attacks can result in data theft, vandalized websites, or the insertion of unauthorized administrators. The following database servers are more vulnerable to SQL injections:
WordPress
Joomla

SQL injection is an attack in SQL servers where malicious codes are inserted into strings that will get pass during execution. SQL servers execute all syntactically valid queries that it receives. Sometimes, that data can be manipulated by someone to attack the server. A simple step that can be taken to defend against such attacks is becoming aware of the weaknesses of the network. Administrators having a clear understanding of the network they have constructed will give them the knowledge on where to focus their defenses. Having an intrusion detection system or intrusion prevention system is a strong defense to have. Those systems will constantly monitor the network for suspicious activities. Another simple. yet effective, defense is setting privileges. Admins should be mindful of who needs access to different sections of the database.A dynamic SQL statement is a statement that changes every time the application is run. They are not part of the source program. They are stored in character strings input or they get built by the application when it gets run. The advantage of using dynamic statements is having a more versatile program that can be built interactively with input from users having little or no knowledge of SQL. The disadvantages are that it requires complex coding, the use of special data structures, and more runtime processing.Every database is vulnerable to SQL injection attacks. These attacks are limited by the attackers skill and imagination. However, older databases are more vulnerable to attacks. PHP and ASP applications are more likely to be attacked due to the fact that they use older functional interfaces.
