I'd be grateful to Scott for building mod_security 2.6.4 for EL4 after the EOL date and get myself a new system ready to migrate to ASAP if I were you.
mod_security 2.6.4 for el4 is available, however you can not use the Plesk WAF. It is not possible to build a working mod_security for that component on el4 any more. Please upgrade to a supported OS if you want to use that component.
And our support policy has always been made available on our website, along with when we stop supporting a platform:https://www.atomicorp.com/wiki/index.ph ... ing_system
Which has always been to only support a platform as long as the vendor supports it. As soon as the vendor stops supporting it, our policy is to do the same. As that means the vendor will no longer be releasing any security fixes - thats a critical issue for us. We never want a customer to be left with a false sense of security. As wonderful as we try to make our products, patching is still an important part of system security. And once the vendor gives up on the system, that means patches will no longer be made available for any security issues (or bug fixes, which is also a problem for any product). And from a security perspective we believe you should not use a system that is no longer supported by the vendor.
We do our best to continue to make updates available for unsupported platforms, but we can't guarantee that will be able to do that either. If the vendor will also no longer fix bugs that impair proper performance of our products, we do not want you to be left with a broken product. Nor can we guarantee that that we can release updates to meet the increasing needs of the evolving security threats our products are designed to combat if the vendor will not fix bugs either.
We wish we could support products forever, but there is a finite limit on the lifetime for any given product, and as a rule if the vendor EOLs a product, we EOL support on the same day.
