+# Security Policy
+
+## Supported Versions
+
+Support is only maintained for the latest version of the library published to [Maven Central](https://central.sonatype.com/artifact/dev.kastle.netty/netty-transport-raknet).
+
+## Reporting a Vulnerability
+
+Vulnerabilities should be reported privately through the [security tab](https://github.com/Kas-tle/NetworkCompatible/security) of the repository. For detailed instructions on this process, see these [instructions](https://docs.github.com/en/code-security/security-advisories/guidance-on-reporting-and-writing-information-about-vulnerabilities/privately-reporting-a-security-vulnerability#privately-reporting-a-security-vulnerability) from GitHub.
+
+After the vulnerability is reported, it will be reviewed as soon as practicable. If a fix is required, a fix will be developed and released as soon as possible. The reporter of the vulnerability will be kept informed of the progress until the vulnerability is resolved.
+
+Once the vulnerability is fixed, the maintainer and reporter will mutually agree on a timeline for publicly disclosing full details of the vulnerability.
