问题:
web管理端登录,提示
当前体系中存在弱加密算法,建议telnet大概CLI登录设备通过命令行display security risk检察并推荐使用安全的加密算法和协议。
控制台具体显示为- [Huawei]display security risk
- Risk level : high
- Feature name : SSH_SERVER
- Risk information : Insecure key exchange algorithm is enabled in SSH server.
- Repair action : It is recommended to disable the insecure key exchange algorithm.
- Risk level : high
- Feature name : SSL
- Risk information : Insecure cipher suite(rsa_aes128_sha256) is enabled in configuring a server-based SSL policy.
- Repair action : It is recommended to disable the insecure cipher suite.
- Risk level : high
- Feature name : SSL
- Risk information : Insecure cipher suite(rsa_aes256_sha256) is enabled in configuring a server-based SSL policy.
- Repair action : It is recommended to disable the insecure cipher suite.
- Risk level : medium
- Feature name : IPSEC
- Risk information : Insecure encryption-algorithm (aes-128) are enabled in IKE proposal.

官方文档未给出具体操作。列一下个人的解决步骤:
原因出在默认配置中存在弱加密算法,存在安全隐患,具体修改时又层层计谋引用嵌套,需要自上而下解决。
IPSEC相关风险出在ike的计谋中:- ike proposal default
- encryption-algorithm aes-gcm-128 aes-gcm-256 sm4
复制代码
ssh服务器:- ssh server key-exchange dh_group14_sha256 dh_group15_sha512
复制代码
ssl的比较麻烦,最后查出来默认计谋是被https服务使用,先排除https服务即可:- undo http secure-server enable
- undo http secure-server ssl-policy
- ssl policy default_policy
- ciphersuite ecdhe_rsa_aes128_gcm_sha256 ecdhe_rsa_aes256_gcm_sha384
- http secure-server ssl-policy default_policy
- http secure-server enable
复制代码
最后再检查,确认告警清除,但是web页依然提示临时忽略。
