Pre-installation notes The guide bellow is based on the previous guide Hardening guide for Apache 2.0 on Solaris 10 platform

SSL implementation phase

  1. Login to the server using Root account.

  2. Mount Solaris 10 DVD, and move to the packages folder: cd /cdrom/sol_10_1008_x86/Solaris_10/Product

  3. Run the command bellow to install OpenSSL packages: pkgadd -d . SUNWopensslr SUNWopenssl-commands SUNWopenssl-include SUNWopenssl-libraries

  4. Create folder for the SSL certificate files: mkdir -p /etc/apache2/ssl.crt

  5. Create folder for the SSL private key: mkdir -p /etc/apache2/ssl.key

  6. Run the command bellow to generate a key pair: /usr/sfw/bin/openssl genrsa -des3 -out /etc/apache2/ssl.key/server.key 1024 Specify a complex pass phrase for the private key (and document it)

  7. Change the permissions on the private key file: chmod 600 /etc/apache2/ssl.key/server.key

  8. Run the command bellow to generate the CSR: /usr/sfw/bin/openssl req -new -newkey rsa:1024 -nodes -keyout /etc/apache2/ssl.key/server.key -out /tmp/apache.csr Note: The command above should be written as one line.

  9. Send the file /tmp/apache.csr to a Certificate Authority server.

  10. As soon as you receive the signed public key from the CA server via email, copy all lines starting with “Begin” and ending with “End” (include those two lines), into notepad, and save the file as “server.crt”

  11. Copy the file “server.crt” using SCP into /etc/apache2/ssl.crt/

  12. Follow the link on the email from the CA server, to create the Root CA chain, and save it as “ca-bundle.crt” (Note: The file must be PEM (base64) encoded).

  13. Copy the file “ca-bundle.crt” using SCP into /etc/apache2/ssl.crt/

  14. Edit using VI the file /etc/apache2/ssl.conf and change the following strings: From: SSLSessionCache dbm:/var/run/apache2/ssl_scacheTo: SSLSessionCache dbm:/var/ apache2/ssl_scache

    From: SSLMutex file:/var/run/apache2/ssl_mutexTo: SSLMutex file:/var/apache2/ssl_mutex

    From: ServerName 127.0.0.1:443To: ServerName Server_FQDN:443

    From: DocumentRoot "/var/apache2/htdocs"To: DocumentRoot "/www"

    From: #SSLCACertificateFile /etc/apache2/ssl.crt/ca-bundle.crtTo: SSLCACertificateFile /etc/apache2/ssl.crt/ca-bundle.crt

    From: SSLCipherSuite ALL:!ADH:!EXPORT56:-AES256-SHA:-DHE-RSA-AES256-SHA:-DHE-DSS-AES256-SHA:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULLTo: SSLCipherSuite ALL:-ADH:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP

  15. Remove the section bellow: <Directory "/var/apache2/cgi-bin">

  16. Stopping Apache from command line: /usr/apache2/bin/apachectl stop

  17. Starting Apache from command line: /usr/apache2/bin/apachectl startssl
