What is Cloud-Based Security?
Cloud based security services are migrating from dedicated hardware solutions to cloud-based security services using a Software as a Service (SAAS) model. The increase in virtualized and cloud networks is boosting demand for cloud based security, because data and applications are now more portable and distributed across a wide variety of networks. This means that security applications need to live as software in the cloud, rather than as dedicated hardware appliances protecting specific points of the network.

Security is Achievable in the Cloud?
If you compared a current survey of “top concerns of cloud adoption” with one from five years ago, you would see the top issue as security, followed by data privacy or protection. Despite the long-standing concerns captured in a myriad of surveys, security in the cloud has progressed to a more practical and achievable level.

New Architectures?
Pursuing a cloud-based security model does have challenges. In order to deliver comprehensive protection, security must be written into the architecture of a network. There are also a wide-range of security needs, which all require different applications and needs. In addition, the move to cloud-based applications poses its own threats. 

The three most pressing cloud issues for businesses remain email security, web security and identity and access management. Throw in bring your own device (BYOD) trend from employees moving around within their company, Distributed Denial of Service (DDoS) attacks, and advanced threats, and many corporate IT managers are finding the need for a multi-faceted approach to security.

One of the largest challenges of implementing cloud-based security is the need to maintain consistent control and visibility across the different domains. With many existing networks, there is a combination of public and private (and even hybrid) cloud-based services, which makes the integration of security services and strategy a big task.
