Oracle Cloud Infrastructure provides a ton of useful services for automating and orchestrating behaviours in your cloud environment, and while they are often pretty handy on their own, leveraging them together gives almost complete flexibility on what you can achieve. Want to trigger a backup using a command in slack, then have a message get sent back when it completes? Sure! Want to periodically poll a log API and archive the results? Easy. Oracle Cloud Infrastructure provides a number of inbuilt capabilities, as well as the ability to jump into arbitrary code to build elaborate automation flows, and this blog post will focus upon the security constructs around this, looking at how services can be authorised to invoke one another, as well as how they authenticate themselves, while avoiding storing sensitive data in insecure ways. This post is intended as an overview of the concepts, and will be referenced in more concrete ways in future.

Consumer Data Right (CDR) – User-specific Identifiers for ID Permanence
Version 1.0.0 of the Consumer Data Right standard was released in September, and it introduces a common set of Banking APIs in line with Australian government legislation. The principles behind the standards design are very solid, though the some of the specific requirements are pretty wild and they result in a bit of rethinking of some of the classical API conventions. The most prominent example of this is the approach the CDR standards take towards ‘object identifiers’, in the ID Permanence section, and I considered the requirements for this interesting enough to spend some time thinking about and documenting.
In this context, an ‘object identifier’ refers to the way in which you refer to an individual instance of an object from your API, such as the ‘accountId’ in the following URI:
GET /banking/accounts/{accountId}
In this blog post we will look at what the CDR requires for these types of identifiers, and provide some sample code which implements the obfuscation requirements specified in the standard.

Oracle recently introduced a Web Application Firewall (WAF) to further enhance and secure Oracle Cloud Infrastructure offerings. The Oracle Cloud Infrastructure WAF is based on Oracle Zenedge and Oracle Dyn technologies. It inspects all traffic destined to your web application origin and identifies and blocks all malicious traffic. The WAF offers the following tools, which can be used on any website, regardless of where it is being hosted:
- Origin management
- Bot management
- Access control
- Over 250 robust protection rules that include the OWASP rulesets to protect against SQL injection, cross-site scripting, HTML injection, and more
In this post, I configure a set of access control WAF policies to a website. Access control defines explicit actions for requests that meet conditions based on URI, request headers, client IP address, or countries and regions.
Using Public/Private Key Authentication for Oracle IDCS
In a recent blog post, I added a throwaway reference to the use of signed assertions as a better mechanism for interacting with the Oracle Identity Cloud Service REST APIs than the use of Client id/secret, though qualified it with ‘if you want to handle the additional complexity in your consuming client’. Reflecting upon this, I thought that perhaps it was worth trying to explain this ‘additional complexity’, since the use of signed assertions have a number of benefits; primarily that it does not require an exchange of sensitive information, as the private keys used to sign the assertion never need to leave the machine on which they are generated. In this blog post, I will delve deeper into what is required to leverage this authentication mechanism, for both clients and users.

Making access easy but secure
So following on from my earlier article, Policies let your teams play safe, I have been given another challenge: Can we give our users single sign on now that each team can play safely in their own Oracle Cloud Infrastructure compartments?
Single sign on delivers a number of really important benefits. Firstly, the user experience is much smoother and seamless as users don’t get prompted for multiple passwords and don’t have to remember even more passwords. More importantly, single sign on eliminates the need to manage multiple stores of identities. This can be a big overhead for administrators and sometimes open up additional risks. Finally, an enterprise wide identity solution can often provide additional capabilities can be leveraged by your Oracle Cloud Infrastructure.
Policies let your teams play safe
Earlier today I was given a challenge by my colleagues. Recently Oracle released the Autonomous Data Warehouse and we have a lot of excitement from customers, partners and internal folk alike. This excitement is driving a lot of innovation right now, but that also brings some challenges. The last thing we want is the Marketing team to mess with Finance resources. How do we make sure different teams don’t step on each other’s toes?
Configure Letsencrypt SSL Certificate in Weblogic 12c
Who doesn’t like the security. This is one of critical element of our IT Infrastructure. Recently I was doing one POC and got requirement to setup a valid SSL certificate in Weblogic. However, since it was just an POC we were not having any valid SSL certificate issued by some Certificate Authority. Later, I came across for one website called https://letsencrypt.org/ . Let’s Encrypt is a free, automated, and open certificate authority (CA). they give people the digital certificates they need in order to enable HTTPS (SSL/TLS) for websites, and its free, yes you heard correctly It’s FREE !!!. You don’t need to pay them at all. So if you need a valid SSL certificate for your POC or even for Production environment you can get one from them. Although their certificate comes with 3 month validity, so while using for Production environment user need to keep renewing with them with simple automated process.
In this blog we will be learning how we can generate letsencrypt SSL certificate, what’s prerequisite to get the certificate and setup that certificate in Weblogic server to enable SSL communication.
So, Lets move on. We will be doing below stuff in sequence –
- Get a registered domain name (This required while generating SSL Cert)
- Install Certbot ACME Tool and Apache HTTP Server
- Generate Letsencrypt SSL Certificate
- Configure Letsencrypt SSL in Weblogic Identity Store

Oracle Cloud Security is Openly Social
Oracle Identity Cloud Service (IDCS) protects Oracle IaaS, PaaS, SaaS and On-Premises applications. Oracle IDCS provides federated single-sign on experience to its clients. It follows open standards such as SAML 2.0, OAuth 2.0 and OpenID Connect 1.0. In the federation model, Oracle IDCS can either act as an Identity Provider (IdP) or a Service Provider (SP) or both.
Oracle IDCS has a built-in feature that provides multiple social identity providers such as Google, Facebook, LinkedIn and Twitter. It uses underlying OAuth 2.0 protocol to interact with the Social Identity providers. This article presents how to configure IDCS to allow for Social Logins. Let me explain this concept with the sequence diagram below:
Your Place or Ours
Sometimes you just want to build a local environment on your own equipment simply because it’s quick and easy. But you soon realise that other people need access and resources get a bit tight (memory, CPU, etc). That’s when it makes sense to move it from your place into the cloud.
Just recently I realised how useful Oracle Virtual Box’s new export feature is for migrating local VMs into Oracle Public Cloud Infrastructure – Compute Classic. Oracle Virtual Box’s new export formats give me the ability to easily migrate Images to the Oracle Public Cloud where I can scale my environments as required.
Earlier this week I was building a new Oracle Identity and Access Management development environment on my laptop. This worked well from an initial build and configure perspective but there comes a time when I need to make this environment available to my Developers, Testers and other stakeholders. Running this image continuously on my laptop quickly becomes impractical even for development teams.
Hey Dude, where’s my keys?
I was asked recently to speak at a Developer forum about ways to make life easier for developers to secure their applications in the cloud. The session was great and lots of questions were asked but perhaps the most surprising question asked was from a developer who wants to integrate a custom application with Oracle Identity Cloud. This developer needs access to the public keys used by Identity Cloud Service before a user has authenticated to the service. More importantly, the developer needs the keys represented in the JWK format. According to the specification, a JSON Web Key (JWK) is a JavaScript Object Notation (JSON) data structure that represents a cryptographic key.
There are very valid reasons why the developer needs access to the public keys without an authenticated session. Public keys let someone verify the signature on something signed with the associated private key or encrypt a message to send to you.
The developer asked Can I get a JWK from Oracle Identity Cloud Service without an OAuth Access Token?
The answer is simple… YES!!! There are two important API’s available in Oracle Identity Cloud Service
