SQL injections. Cross-site scripting. Distributed denial of service (DDoS) attacks. Botnets. These are just some of the cyber-weapons increasingly being used by malicious actors to target web applications, cause data breaches, and expose sensitive business information.
Oracle WAF uses a multilayered approach to protect web applications from a host of cyberthreats including malicious bots, application layer (L7) DDoS attacks, cross-site scripting, SQL injection, and vulnerabilities defined by the Open Web Application Security Project (OWASP). When a threat is identified, Oracle WAF automatically blocks it and alerts security operations teams so they can investigate further.
