Cloud Database Security: What you need to know

There are so many cloud service models and deployment models that it can get very confusing quickly even for IT specialists!

One thing is for sure though. When it comes to updating your cloud technology, you really need to think about data loss prevention, database security, and compliance requirements. The biggest challenge is determining what type of cloud to use, their base security features, and how you can sufficiently protect the data you want it to host.

Cloud Service Models and their Database Security

With the right cloud and an active database security system, your business cloud can be secure. Here are some key points to remember.

1. Software as a Service (SAAS)

What It Is

SaaS is software that is hosted in the cloud and delivered over the web, so that it doesn't take up hard drive or server space. SAAS allows you to store data, customize the web interfacing, and create a web portal to access software that is hosted on others’ servers. This can be multi-tenancial, with each tenant’s data isolated and invisible to others.

The Benefits

With SAAS, your business won’t need to waste resources managing or controlling the network, servers, operating systems, storage, or even individual application capabilities.

Database Security

Security is almost entirely up to the vender and while it is natural to worry about these servers being hacked, the likely truth is that the vender has a high level of security. Many will have multiple secure data centres, automatic-back up systems, and some level of disaster recovery. Here are several ways you can secure your SAAS application. Ask SAAS vendors about their database security regarding planned maintenance activities, multitenant architecture, and reliability of performance, multi-level data-backup procedures, and scalability as your company grows.

2. Platform as a Service (PAAS)

What It Is

PAAS functions at a lower level than SaaS, typically providing a platform on which software can be developed and deployed. PAAS providers abstract much of the work of dealing with servers and leaves users free to focus on the business side of scalability, and the application development of their product or service. This is best for high-level programing and developing of applications.

The Benefits

With PAAS, your IT team can develop and run your applications quickly, without the associated costs and complexity of buying and managing the underlying hardware and software layers.

Database Security

Because PAAS can be public, private, hybrid, mobile, or open, there are varying security risks depending on the type used. Ask PAAS vendors how your application will interact with other applications on the server, if containerisation is used to separate applications, if third-party penetration tests have been done, and what their procedures for security updates is. Here are several ways you can secure your PAAS environment.

3. Infrastructure as a Service (IAAS)

What It Is

IAAS provides public, hybrid, or private cloud storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. Here, your IT team doesn’t manage the underlying cloud physical structure, but controls the operating system, storage, deployed application, and a limited amount of networking components.

The Benefits

IAAS reduces infrastructure costs while providing virtually limitless scalability and agility, along with high level of uptime and ease of mobility. Users are responsible for updating the software if new versions are released.

Database Security

Implementing security controls lays primarily with the user, while the cloud provider will be responsible for network infrastructure, hypervisor security, overall cloud availability, encryption, and key management of data on its storage systems. Ask IAAS vendors about their network infrastructure and recovery systems, acceptable levels of authentication and authorisation to do, and management forms. Users should make efforts to deploy a greater amount of encryption with segregated key management, strong authentication, robust change management processes and other best practices.

Your Cloud Requirements

Your choice in cloud models may depend on your current mobility and collaborative communications strategy. Think also about if your communication systems are prepared for the future. By understanding your requirements and the capabilities you need from your cloud provider, you can start to search for the best provider for you. At Vita Enterprise Solutions, we can audit and assess your existing IT service and learn which workloads and applications will work best for your business and people. You can rely on us to help make the cloud work for your business.

Whether you plan to migrate from public to private, or IAAS to SAAS, or any other requirements, we can assist with the technology transition with our specialist skills and provide ongoing support. Call our experts on 1300 139 310 or enquire online.​
