How to prevent SQL injection attacks

SQL injections are one of the most utilized web attack vectors, used with the goal of retrieving sensitive data from organizations. When you hear about stolen credit cards or password lists, they often happen through SQL injection vulnerabilities. Fortunately, there are ways to protect your website from SQL injection attacks.

SAST, DAST, IAST, and RASP: how to choose?

At the most basic level, application testing is aimed to rule out the possibility of malfunctioning code and to ensure the application runs smoothly after development. Squashing any bugs early on, preferably before they are baked into a final software release, is a challenge many developers face. Keeping the security level on a running application continuously tested will also further save organizations from financial and reputational damage.

What is a web application firewall?

Commonly abbreviated as WAF, a web application firewall is used to filter, block, or monitor inbound and outbound web application HTTP traffic. Compared to intrusion detection systems (IDS/IPS), WAFs have a strong focus on the application traffic and have the ability to provide deep data flow analysis. When IDS/IPS serve as gatekeepers of all network traffic, WAF is only looking for attacks that come from applications, monitoring mostly the HTTP/HTTPS protocol. WAFs inspect the traffic as it comes and goes, preventing common attacks that arise from application code vulnerabilities (cross-site scripting (XSS), SQL injection, etc.).
