以前，HashiCorp Vault 是唯一支持集群范围的 KMS 和持久性卷加密的 KMS。在 OpenShift Data Foundation 4.7.0 和 4.7.1 中，只支持 HashiCorp Vault Key/Value (KV) secret engine API，支持版本 1。从 OpenShift Data Foundation 4.7.2 开始，支持 HashiCorp Vault KV secret Foundation 4.6 中被支持。从 OpenShift Data Foundation 4.7 开始，使用和不使用 HashiCorp Vault KMS 都被支持。从 OpenShift Data Foundation 4.12 开始，使用和不使用 HashiCorp Vault KMS 和 Thales CipherTrust Manager KMS 都被支持。 ![Image](/uploads/d 使用 HashiCorp Vault KMS 进行集群范围内的加密提供了两种身份验证方法： - 令牌：此方法允许使用 vault 令牌进行身份验证。在 openshift-storage 命名空间中创建包含 vault 令牌的 kubernetes secret，用于身份验证。如果选择了这个验证方法，那么管理员必须提供 vault 中后端路径（其中存储了加密密钥）的 vault 令牌。 - Kub

Similarly to storing secrets in HashiCorp Vault, introduced in Zabbix 5.2, CyberArk Vault can be used for: • user macro values • database access access credentials Zabbix provides read-only access to the secrets in vault.

server config verify which is unsafe!") } Not all components follow this practice. The Hashicorp Vault Secretstore component labels the option “Insecure” but does not log a warning. Other components do requests it. The attacker is likely to be an insider who has certain privileges. ## Example 1: Vault If the Vault SecretStore component does not receive a successful response from the remote store, Dapr copies com/dapr/components-contrib/blob/cfbac4d794b35e5da28d65a13369d33383fb6ad4/secretstores/hashicorp/vault/vault.go#L247 if httpresp.StatusCode != http.StatusOK { var b bytes.Buffer io.Copy(&b, httpresp

在配置文件中添加了 Vault 前缀参数 配置文件 zabbix_server.conf 和 zabbix_proxy.conf 已补充了一个新的可选参数 Vault Prefix；zabbix.conf.php 已补充了选项 $DB['VAULT_PREFIX']，并且已相应地更新了 setup.php。 因此，CyberArk 和 HashiCorp 的 vault 路径不再是硬编码的，以便允许使用非标准路径进行 路径不再是硬编码的，以便允许使用非标准路径进行 vault 部署。 ## Agent2 配置 ## 缓冲区大小 Zabbix agent 2 的 BufferSize 配置参数的默认值已从 100 增加到 1000。 ## 允许空值 现在，Zabbix agent 2 上与插件相关的配置参数允许为空值。 ## Proxy 内存缓存 Zabbix proxy 已经支持内存缓存。内存缓存允许将新的数 configuring the TLS connection 的配置信息（该功能仅限数据库类型为 MySQL 或 PostgreSQL）。若选择 HashiCorp Vault 选项来进行凭据存储，请在附加的信息栏中输入相关信息，用以说明 Vault API 端点、隐藏路径以及身份验证令牌： ## ZABBIX ![Image](/uploads/documents/1/a/3/d/1a3d826dd8
