Linux、LDAP、半径

我需要一点帮助来了解我使用 RADIUS+LDAP 的无线登录是否足够安全。

我有这样的基础设施:PC 客户端 (Linux) + ASUS AP Wireless + FreeRadius 和 OPENLDAP 在云中的同一台计算机上。

我配置了一切，现在我可以使用 LDAP 凭据登录。客户端使用带有 TTLS+PAP 的 WPA2 Enterprise，因为 PAP 是唯一可用的协议(protocol)，因为 LDAP 中的密码已加密 (ssha)。

即使我使用 PAP，一切都足够安全吗？

这是登录后 radiusd -x 的回复:

非常感谢您的帮助。

最佳答案

仅当客户端/请求者设置为正确验证 RADIUS 服务器提供的证书时，EAP-TTLS 才是安全的。通常保证这一点的唯一方法是在连接到网络的任何设备上预先配置无线配置文件和请求者设置。

如果您想要安全身份验证，请使用 OpenLDAP 的 PKI 模块，并为每个用户/设备生成证书并使用 EAP-TLS。

参见this presentation关于当前请求者的行为。
