5. perl -pi -e 's/ServerTokens Major/ServerTokens Full/' /etc/httpd/conf/extra/httpd-default.conf
6. perl -pi -e 's/ServerSignature Off/ServerSignature On/' /etc/httpd/conf/extra/httpd-default.conf
7.perl -pi -e 's/ServerSignature EMail/ServerSignature On/' /etc/httpd/conf/extra/httpd-default.conf
8. tar xzf modsecurity-apache_2.5.9.tar.gz
