我有一台 RHEL 9 服务器，我们的漏洞扫描程序在服务器上发现了以下两个我们需要禁用的密码套件。

TLS 1.2 密码：

  • TLS_RSA_WITH_AES_256_CCM
  • TLS_RSA_WITH_AES_256_GCM_SHA384

我找不到在哪里找到它们或禁用它们。我对 Linux 不是很有经验。

据我所知，这不是一个 Web 服务器。我检查了以下位置：

  • 该/etc/crypto-policies/config文件仅列出FUTURE。
  • 命令的输出update-crypto-policies --show是 FUTURE
  • /etc/crypto-policies/policies/除了 modules文件夹外什么也没有列出。
  • /etc/crypto-policies/state有一个名为的文件，CURRENT.pol其信​​息如下：
# Policy FUTURE dump

# Do not parse the contents of this file with automated tools,
# it is provided for review convenience only.

cipher@java-tls = AES-256-GCM AES-256-CCM CHACHA20-POLY1305
protocol@java-tls = TLS1.3 TLS1.2 DTLS1.2

cipher@openssl = AES-256-GCM AES-256-CCM CHACHA20-POLY1305
protocol@openssl = TLS1.3 TLS1.2 DTLS1.2

这是我看到的唯一一个列出密码和其他信息的文件。我尝试注释掉AES-256-GCM并AES-256-CCM添加该cipher语句，然后重启服务器。但漏洞扫描器仍然能够识别这两个密码套件。我cipher@openssl也尝试了同样的语句。

感谢您对禁用这些密码的任何帮助。
