Think innovation, and microservices is the first thing which comes to mind. Microservices has confirmed to be an innovative way to accelerate and enhance software development — this term specifically refers to the application subcomponents, which are formed separately to focus on one specific function. For example, an e-commerce store will have multiple microservices, some of which might pertain to order collection, account recovery, account accesses, and inventory management (including shipping). Big organizations like Amazon, eBay, Netflix, Twitter, rely heavily on microservices to make their e-commerce stores a success story.

Microservices are like containers; they can be reused, are scalable, and can contain different coding languages with ease. Applications can be adjusted easily, without changing the whole program. Considering the possibilities available with microservices security issues don’t come as a surprise. As is the case with every element of technology, there are security issues with microservices, which should be addressed to ensure maximum output in the long run.

Tips to Enhance Microservices Security for Better Performance:

Design Visibility into the Entire Infrastructure
To create a robust security model it is essential first to create a map of each service, and how they are linked to each other. This way, any dependencies can be mapped out, and it will help compare against any aberrations at a later date.

Follow the Concept of ‘Defense in Depth’
Layer each of your network security defenses; firewalls are not enough to defend all your microservices. It’s vital to secure component by component; during this stage, pinpoint any of the sensitive functions and lock them down with a defense-in-depth approach. An example would be to build fine-grained firewalls between services so that containers have safe dividers between the various services.

Security Can be Diversified
Each microservice is like a little container which needs to be locked to prevent unauthorized people from gaining access to the coding and the data. Having said this, what is the best way to secure each container? Diversify your security tactics for each microservice, and don’t keep the same pattern while ensuring the security codes. This way, each microservice is well secured, and there is little or absolutely no need to worry about security.

Enforce APIs for Enhanced Security
Since microservices are all small components joining to make one big app; it’s essential to understand how each part talks to the other over the network. These communications are the biggest challenges which should be recognized. If the application’s services are rigged with sensitive data, then you might need to check if your network is compliant to the required rules and regulations. APIs are the link between each of these components, so it’s necessary to ensure the security of the APIs and keep it up to date at all times. Well-built APIs use features like throttling, access tokens, and authentication features, which can be enforced when the time arises.

Use the Encryption Strategy Best for Your Network
HTTPS transport security is one of the best methods to protect data in transit. When the data is transferring externally from your network, HTTPS transport security can come to your rescue. Measures should also be taken to ensure any data related to microservices is encrypted at rest using robust encryption algorithms. While this might not be a foolproof solution, it is one of the strategies which can be employed in the transit period.

Limit Accesses to Immediate Users
Security is all about letting the right people into a system. If you have a lot of components which need specialized skills, then you need to limit access to the bare minimum. Don’t grant access to all the components to everyone working in the program; limit the access for best results.

Use Automation for Best Results
Manual efforts are a strict no-no in this world of competition. The higher the manual efforts involved, the more restricted would be the interest in the program. Hasten the process and remove all manual efforts — automation is the key to success.

Make Testing a Recurring Feature
Microservices heavily support Agile development methodologies, which can be used for the rapid deployment of new and improved services. Since technology is an ever-changing need, security features also need to be nimble, to be able to adjust as the technological needs change.
