I have an ASA 5510 with the ASA-5510-10 IPS module installed. The IPS signature has not been updated in over 60 days, it appears it just stopped auto updating. The license is current and the current signature version is 7.0.1 E3. I tried manually to update to 7.0.3 E4 and received an error that Engine version 4 is required to update. I cannot find any engine updates on the Cisco support site. Can anyone tell me where I can find the engine updates?
