It would be wonderful to be two places at once. There are plenty of times when the overwhelming demands of a job or life simply seem like too much for one person to handle. When it comes to IT security, centralized management of both Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) can help ease time constraints and make tasks on different clouds easier to accomplish.
PaaS is a type of cloud computing offering in which a service provider delivers a platform to clients, enabling them to develop, run, and manage business applications without the need to build and maintain the infrastructure.
One of the primary advantages of PaaS is that it allows you to devote time and energy to using new applications without worrying about a complex infrastructure behind them. This can lead to faster development and delivery of applications. However, given that PaaS is a cloud-based service, it comes with many of the same risks contained within other cloud offerings, such as information security threats. PaaS is based on the concept of using shared resources, so the security risks include placing critical data into this environment and having the data stolen due to unauthorized access or attacks by hackers. Still, the major cloud providers have been more effective at warding off such breaches.
IaaS differs from PaaS in that it delivers virtualized computing resources to organizations via the internet. In the IaaS model, third-party service providers host hardware equipment, operating systems and other software, servers, storage systems, and various other IT components for customers in a highly automated delivery model.
IaaS provides access to IT resources in a virtualized environment, across a public connection that’s typically the internet. But with IaaS, you are provided access to virtualized components so that you can create your own IT platforms on it—rather than in your own datacenter. As with any other type of cloud service, IaaS comes with several risks of which organizations should be aware. For example, there are security risks that come when employees of the service provider have direct access to the cloud infrastructure, including hardware and networks.
Another challenge is the complexity of managing an IT environment that relies heavily on cloud services provided by an outside entity. Some loss of control will come as a result of relying on a service provider for critical IT functionality, and because IaaS providers own and maintain the infrastructure, management and monitoring might become more difficult.
While both IaaS and PaaS are gaining traction for application development, analytics, and more, they also carry their share of risk. It can often be easier to manage the different tools when you have a network security management interface. Having such an interface in place can streamline tasks; enabling you to view all your firewall traffic and manage all aspects of device configuration, among other tasks.
The Panorama interface in the latest release of Palo Alto’s Next-Generation Security Platform looks to provide such capabilities; standardizing deployment and monitoring of IaaS and PaaS environments. This means that it doesn’t matter if you use AWS, Azure, or Google – your processes are the same and you can integrate the results of your monitoring both between on premise/cloud and different clouds.
“Integrating application operations across on-premise cloud and public cloud environments create a hybrid architecture that is both robust and resilient,” says Gary Ramah, Fuel Board Member. “A cloud-agnostic service platform can alleviate the issues that come with enforcing security policy in multi-cloud environments. Panorama is such a platform.”
As cyberattacks become more sophisticated, a strong network security management system can save you valuable time and energy.
