The detection rule for "Unusually Long Content-Type Length" identifies abnormal behavior in HTTP requests, specifically focusing on the length of the `Content-Type` HTTP header field provided by clients. This analytic leverages the Stream:HTTP data source to extract the `cs_content_type` field, evaluating its length. Uncharacteristically long Content-Type headers (over 100 characters) can be indicative of attempts to exploit application vulnerabilities, evade security measures, or conduct other malicious activities. By analyzing this data, organizations can enhance their security posture by identifying potential attack vectors that may result in unauthorized access or data breaches. The rule is currently marked as experimental, indicating ongoing development and testing. Implementation requires configuring the Splunk Stream App to ensure proper data extraction, emphasizing the need for an appropriate setup before deploying the rule. Mitigating risks associated with false positives is crucial, as legitimate headers rarely exceed the specified length threshold. The analytic emphasizes monitoring web server traffic, contributing to the proactive identification of threats in web application environments.
