Refer to New security requirements for RIAs in 7u51 (January 2014) .
RIAs must contain two things:
- Code signatures from a trusted authority. All code for Applets and Web Start applications must be signed, regardless of its Permissions attributes.
- Manifest Attributes
Permissions
– Introduced in 7u25, and required as of 7u51. Indicates if the RIA should run within the sandbox or require full-permissions.Codebase
– Introduced in 7u25 and optional/encouraged as of 7u51. Points to the known location of the hosted code (e.g. intranet.example.com).
ref another post on stackoverflow, I have the same concern that certificate is expensive for intranet use.
Sign applet and deploy it in intranet.
I am planning to start a new intranet project, should I give up the consideration on applet?
All of my intranet user do not have the ability to connect outside internet, they are in closed network, I highly doubt the need of signed applet......?
