Suggestion for a site getting hacked

A client's site is getting attacked and the ISP has blacklisted the IPs that hacked them but I think after 1-2 hours , these IPs get released and they get hacked ago.  The client doesn't have router and just an firewall.  I can only think of blocking that IPs via ACL (denying traffic from them ) or black hole those traffic by send it to null. Any other suggestions?

Is the site dynamic/script or static html? If its dynamic is it running one of the open source content management systems like Wordpress or Joomla? The plugins for these are frequently how sites are compromised.

Security

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection. Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
