Known Limitations in JUNOS Software Release 9.3 for SRX-series Services Gateways

Intrusion Detection and Prevention (IDP)

This release of JUNOS software for SRX-series devices supports only the following IDP policies:
- Recommended IDP policy template
- DNS_server IDP policy template
- Custom IDP policy with Critical and Major attack groups
IDP supports up to 100 MB for the policy size. You can create a policy with different attacks or attack groups until the size of the policy reaches 100 MB.

By default, the detector embedded in the SRX-series devices has the SIP, SSL, SSH, and MSPRC protocol decoders disabled.
