As businesses look to accelerate application innovation and move more and more workflows to the cloud, their needs can be at odds with the need to secure the data. This article will outline current challenges faced by application developers to protect data in this new cloud/DevOps environment. It will also provide insights on how to eliminate the burdens from the DevOps team while significantly improving the security of data stored in cloud databases.
Businesses are looking to accelerate application innovation and move more workflows to the cloud. Cisco’s Global Cloud index projects a 26 percent growth rate of cloud workloads between 2015 and 2020. As this trend accelerates, IT project owners increasingly run into audit and compliance requirements that prevent transfer of sensitive data outside the traditional security perimeters. The overwhelming benefits of the cloud including the ability to obtain unlimited scalability of infrastructure, set up and tear down rapidly and gain cost advantages due to economies of scale make this trend impossible to contain.
Application Development Challenges in the Cloud Era
As applications migrate to the cloud, application developers are using microservices to accelerate application development because they dramatically reduce development time and help them focus on their key value proposition, be it hailing a cab or booking a place to stay. The success of microservice players including Twilio and Braintree demonstrate the benefits of delegating non-core features such as calling, messaging and payment processing to domain experts.
Surprisingly, when it comes to something as critical as data security, enterprises still leave the burden on the application developers. This distracts them from working on business objectives as they worry about security problems such as how best to encrypt at data and when to change encryption keys—problems best handled by security domain experts.
Securing Cloud Workloads
As it turns out, encryption is not easy to incorporate into enterprise workflows. Encrypting application data prevents databases from processing it. Then there is the problem of managing keys, which could be lost or become stale. Encrypting cloud workloads brings a whole new set of challenges as the issue of control comes up. If the cloud vendor has access to the keys, what prevents them from being subjected to a subpoena from a government that is using national security as justification to decrypt the data? Add to that the complexity of migrating from on-premises databases to the cloud without risking the data.
A pragmatic approach to solving this problem is to use existing encryption solutions that provides the detection, classification, policy enforcement and monitoring of sensitive data at all times. These solutions can protect application data at a columnar level but easily integrate into existing enterprise workflows. Application developers can identify sensitive data based on a data classification matrix and the sensitive data is automatically protected as it is inserted into the database. Using existing cryptography techniques, that data can even be processed without ever being decrypted, ensuring the highest level of security.
