0.3.5 most security settings were in manifest.
Policy is a combination of restrictions described below, however, they can be applied to several objects.
For example, you can make one policy called
my-customer-1, that will contain several tokens, IP restrictions etc.., and apply it to several lambdas, keeping access information in one place.
Currently, lambda can be linked to only one policy, but one policy could be linked to multiple lambdas.
Security checks aimed to restrict access to function to the limited group of clients.
All security checks performed after application resolution. Each rule combined by AND operator. For example, if restrictions by IP defined as well as restrictions by Origin, both limitations will be applied for a client request.
In case of failure the 403 Access Deny will be returned.
- click to any created application
- click to security tab
Restrict incoming requests by
Header should contain one of defined tokens.
public flag is true, the setting will be ignored.
By default, UI generates tokens by UUIDv4 algorithm, however arbitrary text could be used and defined during setup.
The performance almost not impacted regardless number of tokens.
Restrict access by
Origin header. Useful to from where (domains) browser clients could access function.
If at least one origin defined, the security check becomes mandatory.
By standard, the field should contain a domain with protocol (ex: https://example.com) however backend is not checking validity of the content and arbitrary text could be used and defined during setup.
Wildcards not supported.
The performance almost not impacted regardless number of origins.
Restrict access by a client IP.
Not working properly in docker container: docker proxies all requests, so client IP will be a docker IP instead of real address.
Should be defined in default notation
XXX.YYY.ZZZ.TTT, IPv6 has to be supported but not tested.
The performance almost not impacted regardless number of IP.
0.3.8 the following headers are respected if
BEHIND_PROXY=true) flag is set:
The first address in chain will be used as client address.
