SSL redirect browsers if weak encryption to a warning page

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Dear all,

 

I am using Apache Server version: Apache/2.2.3 on Centos 5.4 (Test environment)

On Production Redhat 4 Server version: Apache/2.0.52

 

I have been looking for a way of:

1 – Prevent browsers with lower encryption to use my site, which I can do with the two directives below

SSLProtocol all -SSLv2

SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP

 

2 – Redirect them to a warning page

<Directory "/">
    SSLRequireSSL
    SSLRequire (%{SSL_PROTOCOL} != "SSLv2" and %{SSL_CIPHER_USEKEYSIZE} >= 128) or %{REQUEST_URI} =~ m:^/errors/:
    ErrorDocument 403 /errors/403-ssl.html
</Directory>

 

When I use IE5 to access the site I get the following error:

 

Forbidden

You don't have permission to access / on this server.

 

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

 

 

--------------------------------------------------------------------------------

 

Apache/2.2.3 (CentOS) Server at secure01.grant.co.uk Port 443

 

Bellow is my Virtual Host:

NameVirtualHost 192.168.8.40:443

<VirtualHost 192.168.8.40:443>

        Serveradmin renato.oliveira@xxxxxxxxxxx

        DocumentRoot "/var/www/secure"

        ServerName secure01.granted.co.uk

        ErrorLog logs/secure01-error_log

        CustomLog logs/secure01.granted.co.uk-access_log common

        SSLEngine on

 

    <Directory "/">

        SSLRequireSSL

       SSLRequire (%{SSL_PROTOCOL} != "SSLv2" and %{SSL_CIPHER_USEKEYSIZE} >= 128) or %{REQUEST_URI} =~ m:^/errors/:

        ErrorDocument 403 "Your Browser Does not support 128 Bit Encryption"

   </Directory>

 

 

       SSLProtocol all -SSLv2

       SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP

 

       SSLCertificateFile /etc/httpd/conf/certs/server.crt

       SSLCertificateKeyFile /etc/httpd/conf/certs/server.key

</VirtualHost>

 

If anyone could help me or point to the right direction, give a clue it would be very much appreciated.

I have search loads before posting this question here.

 

Thank you very much in advance

 

Renato
