A web application firewall (WAF) is a security system designed to protect web applications from online attacks. It filters and monitors HTTP traffic to prevent threats and ensure the application remains secure.
Some of our favorite web app security techniques include secure coding practices, regular security audits, implementing HTTPS encryption, using strong authentication methods, and employing web application firewalls. These techniques help protect web applications from common vulnerabilities and threats, ensuring the safety and security of user data.
In a custom web application, several data encryption and security measures can be implemented to protect sensitive information. These measures include implementing secure protocols like HTTPS, encrypting data at rest and in transit, using strong password hashing algorithms, implementing role-based access control, and regularly updating software and patches. Additionally, using a web application firewall, implementing two-factor authentication, and performing regular security audits can enhance the overall security of the custom web application.
To handle and prevent SQL injection attacks in your web application, you should follow a few best practices. First, always sanitize and validate user input to ensure it doesn’t contain any malicious code. Second, use parameterized queries or prepared statements to separate SQL code from data. This helps prevent attackers from injecting SQL code into your queries. Third, limit the privileges of your database user accounts to reduce the impact of a successful attack. Additionally, implement a web application firewall (WAF) to detect and block SQL injection attempts. It’s also advisable to regularly update your software and libraries to patch any known vulnerabilities.
