InterVlan routing security practise

Correct me if I am wrong interVlan routing enables routing between  all vlans present in switched enviroment, , if all VLANs end up routed  to all other VLANs it raises certain security concerns. In a scenario  where there are 50 VLANs and its really hard to build ACLs for every  VLAN. Can anyone recommed any CISCO documentation or white paper which  tells what type of security measures should we consider while enabling  interVlan routing.

If we want to restrict interVlan routing what option do I have apart from implementing ACLs.

Regards,

Farjad
