Kron DAM implements buffer overflow protection at the SQL proxy layer by validating incoming request sizes. If a request exceeds the defined buffer size limit, it is blocked immediately to prevent potential overflow attacks or abuse patterns such as denial-of-service vectors. The mechanism ensures system resilience against malformed or maliciously large queries.

This feature is disabled by default. To enable buffer overflow protection, set the following master parameter:

| **Parameter**                              | **Description**                                                                                                          | **Default** |
| ------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------ | ----------- |
| dam.ddm.buffer.overflow\.attack.protection | Enables the buffer overflow protection mechanism.                                                                        | false       |
| dam.ddm.buffer.overflow\.limit             | Maximum allowed request size in bytes. Values below 8192 bytes are not recommended due to minimum metadata requirements. | 65535B      |

**Behavior and Enforcement**

·         Every SQL request is evaluated against the dam.ddm.buffer.overflow\.limit parameter.

·         If the threshold is exceeded, the SQL proxy discards the request immediately.

·         The offending client IP is blocked until the proxy service is restarted or the protection feature is explicitly disabled.

·         Block actions are logged exclusively in the application.log file.

·         Setting **dam.ddm.buffer.overflow\.attack.protection=false** bypasses this control and exposes the system to buffer overflow risks.
