Ciphers depend on the certificate chain being used - you can introduce problems when connecting to a host which has an insecure signature algorithm used in their chain. For example, we have seen that Office 365 SMTP transport is no longer able to connect to hosts with MD5 and MD2 hashi...
xx/tomcat/conf/server.xml 2)找到 ciphers ,将包含的 DES 去掉,例如: ciphers="TLS_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_DSS_WITH_AES_128_CBC_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256" 3)重启Tomcat (1) 进入Tom...
首先下载IISCrypto.exe,直接下载IIS Crypto GUI并上传到服务器,打开后界面如图(此处已加固): 直接点击左下角推荐设置Best Practices,再取消勾选Ciphers框里的Triple DES 168,即可点击Apply并重启,此时使用nmap复查发现DES/3DES加密套件已消失,漏洞修复完成。 推荐使用该方法进行修复,操作便捷不易出错,且漏洞修复确定性1...
使用Nmap 工具:可以使用 Nmap 的 ssl - enum - ciphers 脚本扫描远程服务器支持的 SSL/TLS 加密算法,命令如nmap -p [端口号] --script ssl-enum-ciphers [目标IP],若结果中显示存在 3DES 等易受攻击的加密算法,则可能存在该漏洞。 利用OpenSSL 工具:通过openssl s_client -connect [目标IP]:[端口号] -ci...

Major browsers are officially removing support for TLS versions 1.0 and 1.1. While versions 1.1 and 1.2 have no known vulnerabilities,TLS 1.3should be the protocol of choice to ensure sites are using only the strongest algorithms and ciphers. TLS 1.3 removed many of the problematic options in pr...
Additional SSL configurations (e.g., protocols, ciphers) can be added here. ... } Test Configuration:Before restarting Nginx, validate the configuration withsudo nginx -t. If it reports no errors, proceed. Restart Nginx:Restart Nginx to apply the SSL configuration:sudo systemctl restart nginx....
From Windows side, we can disable the use of RC4 ciphers on Windows machine. But not sure whether disabling the use of RC4 ciphers on Windows machine will affect the applications mentioned above. For how to enable or disable RC4 on Windows machine, we can edit the registry....
