Introduction
There is no doubt that security is the MOST critical topic for any organizations. Nowadays organizations cannot afford to have any security issues in their solutions. Specially in cloud world, it is extremely important to bridge the gap between development and security.
In my previous blog series Fundamentals of Security in SAP BTP, we learnt how an SAP BTP developer or administrator can onboard themselves on topics related to SAP BTP security.
In this blog, I will provide a complete learning journey to become expert in SAP BTP security. If you are an SAP BTP developer, architect, administrator, or consultant and looking for a complete guided path on how to become expert in SAP BTP security, this blog is exactly for you.
What are the prerequisites to learn SAP BTP Security?
Before you start learning security aspect of SAP BTP, you must gain basic understanding of what SAP BTP is and how to build application on SAP BTP. If you are completely new to the topic, go through below resources to learn basics of SAP BTP.
What is SAP Business Technology Platform (SAP BTP)?
Explaining SAP Business Technology Platform (SAP BTP) to a Beginner
How do I get free access to SAP Business Technology Platform?
Now that you know what SAP BTP is, the next task should be getting a system and explore further.
If you are an SAP partner or customer, you can get started with SAP BTP for free with the Pay-As-You-Go plan. A step-by-step tutorial is also available on how to create SAP BTP account and use.
If you are a student or learner, you can get a free SAP BTP trial account. You may also look into other SAP BTP related product trials.
Note: Don’t overload yourself to become SAP BTP expert before learning security topics. You can parallelly learn SAP BTP while gaining expertise on security.
Let’s start!
Step 1: Get your basics right – Learn fundamentals of SAP BTP Security
If a security professional (or a security code scanner) tells you - “Make sure you Stop SQL injections!”. And you immediate next thought is - “What the hell is SQL injection?”.
Or if you say – “I don’t know OAuth, but I will follow the step-by-step guide to implement it.”
Then - Be 100% sure that your solution will not be fully secure.
Although the implementation might be different across different platforms and languages, there are few basic concepts which are always same. Don’t be too focused on implementing security that you skip the basic concepts behind it. Before implementing security, you should learn these concepts. For example:
- What is SAML?
- How does OAuth work?
- How Does Single Sign-On (SSO) Work?
- What is XSUAA?
- Why do we need App Router in SAP BTP?
- etc.
Go through below materials to get your basics right!
- Fundamentals of Security in SAP BTP
- What is OAuth and how does it work?
- User and Member Management in SAP BTP – Platform users vs Business users
Once you finish the theory, it would great to put it onto action. Complete few hands-on to develop a secure application in SAP BTP.
If you want to quickly proceed to next topics, at least complete the first hands-on from below list.
- Implement Authentication and Authorization in a Node.js App
- Implement Restrictions and Roles in SAP Cloud Application Programming Model
- Secure Your Java Application on SAP BTP
Step 2: Become Expert in SAP BTP Security
Once you finish the fundamental topics, it’s time to go in-depth in SAP BTP Security. Go through below materials to become expert.
SAP Cloud Identity Services
SAP Cloud Identity Authentication service (IAS) and SAP Cloud Identity Provisioning service (IPS) are now part of the product SAP Cloud Identity Services. SAP has combined them under one official product name, but technically they are independent services.
SAP Cloud Identity Authentication service (IAS) enables single sign-on for SAP cloud business. It serves in principle two fundamental usage scenarios:
- It can act as an identity provider (IdP) that validates user’s credentials and offers single sign-on for relying parties
- It can act as a proxy for integration into an already existing single sign-on infrastructure with a corporate IdP.
To know more about it, check SAP Cloud Identity Services - Identity Authentication
SAP Cloud Identity Provisioning service (IPS) enables user data synchronization between different SAP applications. For example: If a company uses SAP SuccessFactors, they would like for every new employee created in SAP SuccessFactors to automatically have a user in Identity Authentication, so they can access SAP S/4HANA cloud. Many SAP cloud solutions come pre-integrated with this service and SAP continues to expand this list of applications.
To know more about it, check SAP Cloud Identity Services - Identity Provisioning
SAP Cloud Application Programming Model (CAP)
SAP Cloud Application Programming Model is
- Not a specific product but a framework, a set of tools, languages, and libraries.
- It brings together SAP’s own technologies like SAP Business Application Studio, Core Data Services (CDS), SAP HANA and open-source technologies like Node.js or Java
- And lets you efficiently and rapidly build enterprise services and business applications in a full-stack development approach
CAP offers out-of-the-box support for security implementations. It does not require you to manually code for authorization while still gives you flexibility to design in your way.
If you are developing a full-stack enterprise application on SAP BTP, SAP highly recommends using CAP.
To know more about it, check below materials:
SAP Credential Store
SAP Credential Store service provides a repository for passwords, keys and keyrings for applications that are running on SAP BTP.
It enables the applications to retrieve credentials and use them for authentication to external services, or to perform cryptographic operations and TLS communication. SAP Credential Store is exposed to the applications via a REST API.
To know more about SAP Credential Store, check below materials:
SAP Custom Domain Service
SAP Custom Domain service allows subaccount owners to make their SAP BTP applications accessible via a custom domain that is different from the default one (hana.ondemand.com) - for example www.myshop.com.
To know more about it, check below materials:
SAP Custom Domain Service – help page
SAP Custom Domain Service – Discovery Center
