JAVA.INSEC.DTP : Deprecated Transfer Protocol (Java)

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

JAVA.INSEC.DTP : Deprecated Transfer Protocol (Java)

要旨

An unsafe or deprecated transfer protocol is used inside a transfer method.

The SSL2 and SSL protocols are considered unsafe.

Some or all TLS versions are considered unsafe, depending on the setting of JAVA_ANALYSIS_STRICT_MODE:

JAVA_ANALYSIS_STRICT_MODE=No	TLS v1, and TLS v1.1 are considered unsafe.
JAVA_ANALYSIS_STRICT_MODE=Yes	All TLS versions are considered unsafe.

例

import java.security.NoSuchAlgorithmException;
import java.security.NoSuchProviderException;
import java.security.Provider;

public class UnsafeTransferProtocol{

  public void transferProtocol(Provider p) throws NoSuchAlgorithmException, NoSuchProviderException {
      javax.net.ssl.SSLContext.getInstance("TLSv1.1");           // "Deprecated Transfer Protocol (Java)" warning issued here
      javax.net.ssl.SSLContext.getInstance("SSL","my_provider"); // "Deprecated Transfer Protocol (Java)" warning issued here
      javax.net.ssl.SSLContext.getInstance("SSL3",p);            // "Deprecated Transfer Protocol (Java)" warning issued here
      javax.net.ssl.SSLContext.getInstance("TLSv1.3",p);
  }
}

解決法

Parameterize it in a configuration file.

Use safer protocols.
