Next-generation access control is undergoing a bit of an identity crisis. Some call it eXternalized Authorization Management, others Dynamic Access Control and still others just refer to it as Attribute Based Access Control (ABAC). Until now, XACML and ABAC have been the two pillars supporting next-gen AuthZ. Gartner predicts that 70% of enterprises will adopt ABAC by 2020.
With ALFA, REST, and JSON, even the most complex authorization scenarios become extremely simple to implement. It's haute cuisine made simple. In this session, we will go hands-on with examples, live demos, coding, and delicious samples.
Equivalences and diffrences between SysML and Arcadia / CapellaObeo
Designing complex and critical systems requires a level of rigor in engineering practices that only formalized and tool-supported modeling approaches can provide.
The Arcadia / Capella solution embeds a methodological guidance that constitutes one of its most significant originalities and success factors. By lowering the learning curve for systems engineers, Capella is an enabler for large scale MBSE adoption.
Largely inspired from several industry standards, Arcadia / Capella simultaneously form an enrichment and a simplification of SysML: a large proportion of the core concepts of the Arcadia method are aligned on the SysML ones, and most SysML diagrams have twins in Capella.
In this webinar, we will:
- Show to which extent Arcadia / Capella can be considered as a “SysML-like” solution, by illustrating diagrams and concepts equivalences
- Present the main differences between SysML and Arcadia / Capella
and provide rationales

Anatomy of a Spring Boot App with Clean Architecture - Spring I/O 2023Steve Pember
In this presentation we will present the general philosophy of Clean Architecture, Hexagonal Architecture, and Ports & Adapters: discussing why these approaches are useful and general guidelines for introducing them to your code. Chiefly, we will show how to implement these patterns within your Spring (Boot) Applications. Through a publicly available reference app, we will demonstrate what these concepts can look like within Spring and walkthrough a handful of scenarios: isolating core business logic, ease of testing, and adding a new feature or two.

Postman: An Introduction for API Ops ProfessionalsPostman
This one-hour, introductory Postman training is geared specifically for API Ops professionals. In this session, you'll learn all the basic skills you need to get started with Postman
Here at Veruscript, we have many edge case scenarios where we need fine-grained access controls in our academic journal publishing platform.
Therefore performing authorisation to a resource by analysing any number of arbitrary attributes allows for the application to scale appropriately. Known as Attribute-Based Access Control (ABAC), these attributes are evaluated regardless of context; This could be username, role, organisation, domain, time-of-day, country, is the Queen of England, because the sky is blue, etc.
It is why Security Voters are the recommended way to check for user permissions in Symfony applications. Security Voters provide a mechanism that has a small learning curve to set up these fine-grained restrictions in Symfony applications using attributes.
In the simplest case, only a minimal amount of setup and configuration is required, the main advantage over ACLs. In the most complex case, policies can be added or modified without significant changes to the codebase.
The talk will compare different access control paradigms: ABAC, RBAC and ACL, and will look into detail one specification for ABAC - Extensible Access Control Markup Language (XACML) and how this might be implemented in Symfony, for those considering a more "enterprise" use of Security Voters.

XACML for Developers - Updates, New Tools, & Patterns for the Eager #IAM Deve...David Brossard
In this presentation I introduce the basics of Attribute-based Access Control, XACML, and why it matters to developers. I also focus on the latest XACML TC profiles - the REST profile and the JSON profile that make integration easier and faster.
Access Control is a necessary security control at almost every layer within a web application. This talk will discuss several of the key access control anti-patterns commonly found during website security audits. These access control anti-patterns include hard-coded security policies, lack of horizontal access control, and "fail open" access control mechanisms. In reviewing these and other access control problems, we will discuss and design a positive access control mechanism that is data contextual, activity based, configurable, flexible, and deny-by-default - among other positive design attributes that make up a robust web-based access-control mechanism.

CIS 2015- Rethinking Your Authorization Strategy- Gerry GebelCloudIDSummit
Still stuck on Role-Based Access Control and its limitations? Exploring Attribute-Based Access Control and not sure where to start? Getting more pressure from business owners to support advanced collaboration and data sharing scenarios – your most critical, sensitive and valuable data? Application and security architects continue to struggle with the difficult task of balancing security protections and compliance regulations against business desires for more open collaboration through the sharing of sensitive and valuable information. This session will review a range of authorization approaches, standards and architectures – from legacy to current to future possibilities. Let’s explore how to address your current requirements while keeping an eye on trends that will shape future security models.
CIS14: Baking Fine-Grained Authorization Into Your Apps and APIs using ALFA, ...CloudIDSummit
Next-generation access control is undergoing a bit of an identity crisis. Some call it eXternalized Authorization Management, others Dynamic Access Control and still others just refer to it as Attribute Based Access Control (ABAC). Until now, XACML and ABAC have been the two pillars supporting next-gen AuthZ. Gartner predicts that 70% of enterprises will adopt ABAC by 2020.
Authorization - it's not just about who you areDavid Brossard
Worried about who's getting access to your app? Sprinkle in XACML and get access control that is both context-aware, externalized and dynamic.
Need to add more than basic access control to your application? Existing authorization frameworks including their pros and cons, but are typically quite limited. This talk will introduce XACML, the eXtensible Access Control Markup Language, an authorization standard from OASIS that defines fine-grained access control based on attributes. The XACML standard enables much more dynamic authorization that not only focuses on the user but also on resources, actions, and the context. XACML enables policy-based and attribute-based access control.
The talk with then look at how XACML can be used to apply authorization business rules to any Java application and even beyond (.NET, Ruby...). This is known as “any-breadth authorization”. XACML also enables consistent authorization across multiple layers (presentation tier; web tier; business tier; and data tier). It becomes possible to apply the same authorization logic in a JSF page as in a jdbc connection. This is also known as “any-depth authorization”
During the talk, we will look at live examples of applications using XACML. For instance, we will demonstrate the use of XACML and Java servlets, JAX-WS web services, and APIs as a whole. Attendees will also be able to write their own XACML policies, provided they download the ALFA plugin for Eclipse, an add-on for XACML policy authoring.
In January 2013, XACML 3.0 was approved as a formal standard and there are several implementations available (open-source, free, and commercial) for developers to get started. The talk will illustrate how developers can leverage XACML to quickly apply authorization to new and existing applications. After this session, you will easily be able to add standards-based authorization to your application - and simplify your life!
OWASP Chicago 2016 - What is Attribute Based Access Control (ABAC)?David Brossard
In this presentation, I cover the history of access control, from simpler models e.g. access control lists (ACL) to Role Based Access Control (RBAC) and eventually Attribute Based Access Control (ABAC). I then discuss limitations of RBAC and how ABAC provides a better alternative using attributes and policies.
CIS14: The Very Latest in Authorization StandardsCloudIDSummit
Gerry Gebel, Axiomatics
Update on the latest trends and happenings regarding authorization standards and commentary on projections on this topic for the coming year, including status of the JSON and REST profiles for XACML (it’s not just XML anymore), scenarios where OAuth and XACML can coexist, and what NIST’s published report on ABAC is all about.
Policy enabling your services - using elastic dynamic authorization to contro...David Brossard
APIs have become the backbone of many services nowadays - from the weather forecast to delivery notifications and photo printing services. Not only can we consume data and services more readily through those APIs but we can also mash them up into greater services. To do so, we tackled API security through OAuth and OpenID Connect. They form a good basis to handle authentication and basic authorization delegation, but there is so much more to consider from an authorization perspective. This session will discuss how security concerns can be addressed through policy-driven authorization in a way that meets the needs and expectations of application developers, owners, and auditors alike. We will show how complex access policies can be handled through a dedicated authorization microservice. With this approach, you can automate security deployment changes within the same CI/CD pipelines used for application management. Furthermore, new deployment configurations are possible, such as implementing the authorization service as a sidecar, to meet advanced performance and scale requirements. All this without changing a single line of code.
How Open Policy Agent (OPA) helps in externalizing authorization from Code in Micro Services world. Before that let's look how Authorization evolved in last decade.
Serverless computing allows you to build and run applications without the need for provisioning or managing servers. With serverless computing, you can build web, mobile, and IoT backends; run stream processing or big data workloads; run chatbots, and more. In this session, you’ll learn how to get started with serverless computing with AWS Lambda, which lets you run code without provisioning or managing servers. We’ll introduce you to the basics of building with Lambda and how you can benefit from features such as continuous scaling, built-in high availability, integrations with AWS and third-party apps, and subsecond metering pricing. We’ll also introduce you to the broader portfolio of AWS services that help you build serverless applications with Lambda, including Amazon API Gateway, Amazon DynamoDB, AWS Step Functions, and more.

ABAC, ReBAC, Zanzibar, ALFA… How Should I Implement AuthZ in My APIs - Nordi...David Brossard
During Nordic APIs 2024, I discussed the different authorization approaches to securing APIs. Much like authentication (via OAuth and other) is externalized from the API, so should authorization. There are different options ranging from ABAC (attribute-based access control) to ReBAC (relationship-based access control).
This presentation talks about the OWASP challenges developers are faced with and how externalized authorization can help address them in a clean and efficient way. We also look into an example of fine-grained authorization using ALFA, the Abbreviated Language For Authorization.
The Holy Grail of IAM: Getting to Grips with AuthorizationDavid Brossard
Tackling authorization in your apps and APIs shouldn't be hard. Learn how to decouple your app code from your authorization code, externalize to an authorization framework, leverage a policy language e.g. ALFA, and enable secure access to your APIs. In this presentation we compare and contrast different authorization approaches such as ABAC, ReBAC, Zanzibar, and more.
An overview of the ALFA Abbreviated Language for Authorization and how it accepts authorization requests and produces authorization decisions that are returned to a client.
As of October 2023, the OpenID Foundation has launched a new working group to tackle challenges around externalized authorization. The group brings together vendors, customers, and R&D partners to drive the design and adoption of authorization patterns.
The purpose of the AuthZEN WG is to provide standard mechanisms, protocols and formats to communicate authorization related information between components within one organization or across organizations, which may have been developed or sourced from different entities.
