1. (I) An
internetwork gateway that separates trusted (or relatively more trusted) hosts
on one side from untrusted (or less trusted) hosts on the other side. (See:
firewall and guard.)
2. (O) /IPsec/
"An intermediate system that implements IPsec protocols." [R4301]
[RFC4949:2007]
A security
gateway is a point of connection between networks, or between subgroups within
networks, or between software applications within different security domains
intended to protect a network according to a given security policy. A security
gateway comprises more than only firewalls; the term includes routers and
switches which provide the functionality of access control and encryption. [ISO-18028-3:2005]
Cloud security gateways are on-premises or cloud-based security policy enforcement points
placed between cloud service consumers and cloud service providers to interject
enterprise security policies as the cloud-based resources are accessed. Cloud
security gateways consolidate multiple types of security policy enforcement.
Example security policies include authentication, single sign-on,
authorization, security token mapping, encryption, tokenization, logging,
alerting, API control and so on.

Cloud encryption
gateways provide cloud security proxy
(typically at the application level), which performs encryption, tokenization
or both on an item-by-item basis as data flows through the proxy. The
obfuscated (encrypted or tokenized) data can then be stored in a cloud-based software-as-a-service
(SaaS) application, such as salesforce.com. Cloud encryption gateways typically
provide a choice of various encryption and tokenization algorithms, depending
on the strength of protection required and how much format preservation is necessary
(for example, to preserve sorting).
