业主配置了批量对多个网站进行intercept，仅tumblr.com的intercept策略无效果，现场我配置策略进行复测无拦截效果，但有策略命中日志
|
|
|
|
|
|
|
|
|
|
|
|
策略配置详情 及会话日志、策略命中日志 上传到附件
|
|
|

|

希望家里看一下配置是否有误，复测一下，是否家里也存在这种现象，**dongxiaoyan** commented on *2022-04-22T10:56:37.996+0800*:

信息港复测：
|
|
|
|
|
|
策略id：18525，filter为sni：*tumblr.com； Keyring和Decryption Profile使用默认配置：
|
|
|
|
|
|
产生日志，日志拦截状态为SSL.Intercept State:Intercept
|
|
|
|
|
|
未产生SSL.SNI为www.tumblr.com，拦截状态为空的日志：

[~liuju]根据以下截图看：有测试流量命中了拦截策略，且产生了22条拦截日志。

|

|
通过进一步分析 Security Events 日志，发现22条拦截日志中 SNI 都是 tumblr.com 的子网站，并没有 www.tumblr.com 的主网站。
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
进一步排查 SSL Decryption Exclusions(解密流量排除的白名单)，发现 $www.tumblr.com 位于 TSG 的解密流量排除的白名单中。
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
解密流量排除白名单的优先级高于拦截策略。
|
|
|
|
|
|
|
|
|
|
|
|
当拦截策略的 SNI 为 *tumblr.com 时：
|
|
|
|
|
|
|
|
|
|
|
|
访问 tumblr.com 子网站时 SNI 命中拦截策略的 *tumblr.com，故证书替换，
|
|
|
|
|
|
|
|
|
|
|
|
访问 www.tumblr.com 主网站时 SNI 命中解密流量排除白名单的 $www.tumblr.com，故证书不替换。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
补充：信息港环境测试 www.tumblr.com 这个网站从解密排除白名单了里删除后，代理可以拦截成功。

信息港测试环境修改拦截排除：id为195，name为$www.tumblr.com的记录，测试可正常拦截，替换证书。

|
|
|
|
|
|
|
|
|
|
|
|
原因：TSG支持对特定网站不解密（因为商务、隐私等原因)，这些都放到了解密排除列表（SSL Decryption Exclusions
|
|
|
|
|
|
|
|
|
|
|
|
）中。www.tumblr.com就在解密排除列表中，所以没有对其进行替换。
|
|
|
|
|
|
|
|
|
|
|
|
解决：如果业主希望对这个网站进行拦截，可以将解密排除列表中$www.tumblr.com失效。（目前预置的暂时不能删除，只能修改。后续版本会支持预置内容也可以删除或者失效，这个不需要特意跟业主说，目前可以将其修改成个不存在的域名，比如$123456.tumblr.123456。）

内置的解密排除列表应支持删除。
