Now that you have made these changes how can you be sure that they have taken place without having to go to your boss or higher authority just to find that you did them wrong. You will need to restart the computer for this change to take effect.HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\RC4 56/128 HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\RC4 40/128 HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\RC2 40/128

Create a new REG_DWORD called “Enabled” and set the value to 0.

Open up “regedit” from the command line.

More detailed information can be found at Micorsoft’s KB187498 or KB245030 Basically your are modifying the settings that restrict the use of specific protocols and ciphers that are used by the schannel.dll. The third error message says we need to turn off anything for less than 56bits, but this will be accomplished by turning of anything less than 128bits. You need to turn off any encryption suites lower than 128bits. These three error messages pretty much mean that you need to turn off SSL 2.0 due to exploits that were found after the standard was created. Here is the list of weak SSL ciphers supported by the remote server :ĮXP-RC2-CBC-MD5 Kx=RSA(512) Au=RSA Enc=RC2(40) Mac=MD5 exportĮXP-RC4-MD5 Kx=RSA(512) Au=RSA Enc=RC4(40) Mac=MD5 export Reconfigure the affected application if possible to avoid use of weak The remote host supports the use of SSL ciphers that offer either weak The remote service supports the use of weak SSL ciphers.

Here are the medium strength SSL ciphers supported by the remote server : Reconfigure the affected application if possible to avoid use of Note: This is considerably easier to exploit if the attacker is on the Lengths at least 56 bits and less than 112 bits. Strength encryption, which we currently regard as those with key The remote host supports the use of SSL ciphers that offer medium The remote service supports the use of medium strength SSL ciphers. SSL Medium Strength Cipher Suites Supported These issues to conduct man-in-the-middle attacks or decryptĬommunications between the affected service and clients.Ĭonsult the application's documentation to disable SSL 2.0 and use SSL Reportedly suffers from several cryptographic flaws and has beenĭeprecated for several years. The remote service accepts connections encrypted using SSL 2.0, which The remote service encrypts traffic using a protocol with known The report they university sent me was generated by Nessus generated errors like this: SSL Version 2 (v2) Protocol Detection These problems would have to be solved before they would allow the new server though the firewalls. Unfortunately this turned up several errors, all of them had to do with Secure Sockets Layer or SSL which in Microsoft Windows Server 2003 / Internet Information Server 6 out of the box support both unsecure protocols and cipher suites. This required that university networking group scan the new webserver with a tool called Nessus.

I recently undertook the process of moving websites to different servers here at work.
