The detection rule 'SQL Injection with Long URLs' aims to identify potential SQL injection attacks by analyzing web traffic data for URL lengths exceeding 1024 characters or HTTP user-agent lengths greater than 200 characters. SQL injection, a major security threat, allows attackers to inject malicious SQL queries into input fields, leading to unauthorized database manipulation and potential data breaches. This analytics rule utilizes the Splunk platform's capabilities and requires monitoring network communications to web servers, ensuring that the Web data model is populated. It counts occurrences of specific SQL keywords within the URLs to gauge the severity of the attack. If more than three SQL commands are detected in a single URL, an alert is triggered, indicating a possible attack.
