8. HOW DOES CASB WORK?
8
>> CASB is
connected to cloud
service API
>> Monitors usage
irrespective of how
and where the cloud
services are
accessed
>> Covers tracking
of the usage out of
org network on
unmanaged devices
API Model
>> CASB is
deployed On Prem
or on Cloud
>> Users are
installed with self-
signed certificates
>> Intrusive
deployment as the
user traffic is routed
through CASB
Forward
Proxy
>> Most common
method for
deploying CASB
>> Replaces IAM
service for
authentication
>> Easier way to
implement for cloud
end users
Reverse Proxy
