ACaaS: Cloud-Based Security Access Control
Access Control as a Service (ACaaS) offer two types of services: rack server and true cloud server. True cloud ACaaS is described as being redundant, on-demand and “multi-tenant”, which defines a software architecture principle in which one occurrence of a software operates on servers that accommodate multiple organizations as clients, or “tenants”, to use cloud computing terminology. However, multi-tenancy permits partitioning of data sets on the server in order to prevent security breaches from occurring among client information centers. Additionally, ACaaS is scalable, another cloud computing term that indicates the ability of a client to increase or reduce the number of doors or users without experiencing delays or unnecessary expenditures of time or money. Finally, one of ACaaS's most popular features lies in its redundancy. This means that the system is always supported by reliable back-up servers so that if the system suffers failures, customers are not affected and data is not lost.
Although rack servers are still considered a type of cloud service, they do not provide all the benefits that a “true” cloud offers.
Rack servers basically extend the connection of the a network to another location instead of having an on-site server closet. The majority of Access Control as a Service providers are rack servers but cannot be called true cloud because of the high costs correlated with constructing data centers that are entirely private. There is also the complexity involved with affording multi-tenancy solutions that enhance the strong maintenance of securing all identities within the cloud. Consequently, companies specializing in ACaaS solutions are alarm and security businesses, area dealers and software providers who deal with an exclusive customer base so that they can best accommodate each client's unique needs.
So that data management and security issues are properly addressed in an ACaaS environment, solutions provided are usually seamless, easily implemented and allows managers to exert complete control over authorization of validated users by being able to revoke access in real-time. Acquisition of transparency regarding the behaviors of all users involved is available via reports delineating user access data. Most Security as a Service applications are also standardized and ready for use by mobile devices and for those outside the network.
Benefits of ACaaS
Because companies do not need to purchase extra hardware or software or pay for servers and the often lengthy times required to set up and configure a server, administrators receive an immediate return of investment by using ACaaS to surround company data with non-invasive, security services.
With licensed software, users traditionally have to wait for upgrades to be released to the public, which can take a year or two following development. With software as a service systems like ACaaS, users will have almost immediate access to the newest technology and innovations exclusive to cloud-supported applications.
Finally, subscribing to a cloud security service means you receive support that addresses your needs rather the needs of millions of other customers. With software that requires installation and configuration, companies must sometimes adjust their operational demands to match the interests of the software, a sometimes costly and time-consuming action.
