The document discusses how cloud metadata and Ansible dynamic inventory can help DevOps and security teams collaborate more effectively. It provides examples of how metadata tagging servers can enable targeted operations like provisioning, patching, software installation based on tags. This allows implementing security processes into continuous delivery pipelines through automated and flexible configuration of servers. The speaker advocates that DevOps and security teams work together to build pipelines that use metadata and dynamic inventory to make security part of standard operations.

If you’ve come across the many “Serverless vs. Containers” articles that exist you may think that serverless and containers are engaged in an epic battle for dominance of cloud-native architecture. Don’t believe this hype, which is more geared toward driving blog post clicks than describing the actual technical landscape. In fact, Containers and Functions both have serverless use cases and aren’t mutually exclusive. In this talk will dive into serverless container services and when, why, and how our serverless team at Stackery integrates container workloads into our serverless architectures.

The serverless movement represents a paradigm shift in our ability to create impressive, scalable web applications and services. Redesigning how triggers can generate and execute events can be an extremely cost-effective solution for microservices and large projects alike. Why serverless? It's less complex, scales easily, and usually costs less. The challenge today is that you may be creating these functions specific to a cloud vendor's API gateway, rather than creating the functions that are most reliable and useful. In this session, you will learn how to create a cloud-agnostic serverless execution backend for your APIs. We will show you how to use Postman APIs with Nimbella’s tooling so you have cloud-agnostic runtime environment that can run in any cloud, including private infrastructure when required. If you are building scalable web applications that you want to deploy on any cloud or private cloud, this is a must-attend session.

Serverless architectures let you build and deploy applications and services with infrastructure resources that require zero administration. In the past, you had to provision and scale servers to run your application code, install and operate distributed databases, and build and run custom software to handle API requests. Now, AWS provides a stack of scalable, fully-managed services that eliminates these operational complexities. In this session, you will learn about the benefits of serverless architectures and the basics of the serverless stack AWS provides. We will also walk through how you can use serverless architectures for everything from data processing to mobile and web backends. AWS DevDay San Francisco, June 21, 2016.

Ansible is a simple, but powerful automation tool with an agentless footprint that allows for the definition of architecture, intent, and policy as code that can be deployed across both on-prem and cloud infrastructure. This enables customers to extend their enterprise and applications into AWS in a way that maintains a consistent, secure posture as part of a continuous delivery pipeline. Customers can then natively integrate with AWS to seamlessly configure and deploy a range of AWS services such as Amazon Aurora, Amazon Redshift, Amazon EMR, Amazon Athena, Amazon CloudFront, Amazon Route 53, and Elastic Load Balancing from within Red Hat OpenShift across a secure, consistent hybrid cloud infrastructure. In this session, we will demonstrate how infrastructure can be instantiated with code as part of a continuous delivery pipeline and describe how that integrates with an OpenShift hybrid cloud deployment.

IT needs to run in production in order to generate business value. DevOps is among other things a way of thinking focusing on production software. A business application requires a tailor made platform to generate business value. The combination of application and its platform is a DevOps product. The DevOps team has full responsibility for that product through its entire lifecycle. The microservices architecture promises flexibility, scalability, and optimal use of compute resources. Via independent components with well-defined scope and responsibility, interface, and ownership that are evolved and managed in an automated DevOps process, this architecture leverages current technologies and hard-learned insights from past decades. This session defines the objectives of Business with IT, of microservices and DevOps and introduces Containers and the container platform Kubernetes as crucial ingredients for making DevOps happen.

Cloud system configurations and their dependencies can quickly grow into the thousands of virtual machine, network and storage components. Once software is included, the number of components can easily rise into six figures. Frequent releases using continuous integration and deployment tools makes a repository of these components and relationships absolutely critical to cloud system integrity and quality of service no matter what cloud management tools you use. Systems configurations are more naturally represented using a graph database than the relational representations used by traditional IT management products. Our talk will explore how we use Neo4J to create a live, active, self-updating repository service, containing nearly all virtual hardware, network and software components and their dependencies, enabling continuous deployment in any cloud environment at scale.

Xavier Garceau-Aranda Senior Security Consultant at NCC Group With the steady rise of cloud adoption, a number of organizations find themselves splitting their resources between multiple cloud providers. While the readiness to deal with security in cloud native environments has been improving, the multi-cloud paradigm poses new challenges. The workshop will aim to familiarize attendees with Scout Suite (https://github.com/nccgroup/ScoutSuite), a key component of NCC Group’s cloud agnostic approach to security assurance. Scout Suite is an open source multi-cloud security-auditing tool, which enables security posture assessment of cloud environments. Using the APIs exposed by cloud providers, Scout Suite gathers configuration data for manual inspection and highlights risk areas. Rather than pouring through dozens of pages on the web consoles, Scout Suite provides a clear view of the attack surface automatically. The following cloud providers are currently supported: - Amazon Web Services - Microsoft Azure - Google Cloud Platform - Oracle Cloud Infrastructure - Alibaba Cloud During the workshop, attendees will leverage Scout Suite to assess a number of cloud environments designed to simulate typical flaws. We will display how the tool can be leveraged to quickly identify and help with remediation of security misconfigurations.

Jan Harrie Security Analyst at ERNW GmbH OpenShift by Red Hat is one of the major Platform as a Service (PaaS) solutions on the market. It is used to automatically deploy Kubernetes clusters and provides useful extensions for cluster management mixed with some magic under the hood. Instantiating a Kubernetes cluster is often a crucial step in setting up a modern application stack. But be aware – a lot of configuration parameters are awaiting you. And here several misconfigurations may occur that can lead up to a compromise of the cluster. Privileged containers, tainting of masters and executing workloads on them, missing role-based access controls, and misconfigured Service Accounts are part of the problem. In this talk, I will explain which configuration parameters of an OpenShift environment are critical to ensure the overall security of the deployed Kubernetes clusters. Implications of misconfigurations will be demonstrated during live demos. Finally, recommendations for a secure configuration are provided.

Matt Carroll Infrastructure Security Engineer at Yelp "Attestation is hard" is something you might hear from security researchers tracking nation states and APTs, but it's actually pretty true for most network-connected systems! Modern deployment methodologies mean that disparate teams create workloads for shared worker-hosts (ranging from Jenkins to Kubernetes and all the other orchestrators and CI tools in-between), meaning that at any given moment your hosts could be running any one of a number of services, connecting to who-knows-what on the internet. So when your network-based intrusion detection system (IDS) opaquely declares that one of these machines has made an "anomalous" network connection, how do you even determine if it's business as usual? Sure you can log on to the host to try and figure it out, but (in case you hadn't noticed) computers are pretty fast these days, and once the connection is closed it might as well not have happened... Assuming it wasn't actually a reverse shell... At Yelp we turned to the Linux kernel to tell us whodunit! Utilizing the Linux kernel's eBPF subsystem - an in-kernel VM with syscall hooking capabilities - we're able to aggregate metadata about the calling process tree for any internet-bound TCP connection by filtering IPs and ports in-kernel and enriching with process tree information in userland. The result is "pidtree-bcc": a supplementary IDS. Now whenever there's an alert for a suspicious connection, we just search for it in our SIEM (spoiler alert: it's nearly always an engineer doing something "innovative")! And the cherry on top? It's stupid fast with negligible overhead, creating a much higher signal-to-noise ratio than the kernels firehose-like audit subsystems. This talk will look at how you can tune the signal-to-noise ratio of your IDS by making it reflect your business logic and common usage patterns, get more work done by reducing MTTR for false positives, use eBPF and the kernel to do all the hard work for you, accidentally load test your new IDS by not filtering all RFC-1918 addresses, and abuse Docker to get to production ASAP! As well as looking at some of the technologies that the kernel puts at your disposal, this talk will also tell pidtree-bcc's road from hackathon project to production system and how focus on demonstrating business value early on allowed the organization to give us buy-in to build and deploy a brand new project from scratch.

Kristóf Tóth Software Engineer at Avatao The world is getting eaten alive by software. At this point, almost nothing can be done without interacting with some sort of software system. Not even buying your groceries. As we keep dumping out huge piles of code like there is no tomorrow, our far from perfect systems keep getting worse and worse from a security standpoint. What could possibly go wrong? We believe that education is the missing link. As appsec is still a curiosity topic on top universities, freshly graduated engineers simply have no clue. And how could they? The number of programmers keeps on doubling every few years and generations of software professionals are stuck without a proper background in ITSec. As this trend continues, our responsibility to do something about this is on the rise. In hopes of fighting this trend, we, at Avatao, have decided to share some of our dreams with the community. Our Tutorial Framework allows you to easily create interactive learning environments running inside Docker containers. These environments are capable of automatically guiding users through a set of topics by allowing them to interact with real software through a simple web browser. Users can attack webservices, write code to fix them or use a terminal to deploy websites by creating and pushing git tags. Nothing here is a mock-up: Every software component is real. In this talk, I am going to demonstrate the capabilities of the framework, talk about the technology behind it and explore some use cases for it. During the session we will open source the framework with the hope of creating a better, secure future together.

Sitaraman Lakshminarayanan Sr Security Architect at Pure Storage Authorization has two components – Policy Definition and Policy Enforcement. Traditionally both used to be centralized and we spent all the time Integrating products- Built or Bought with Centralized Access Management. This typically led to increased cycle time to change any access policy or change software/deployment to fit into one particular authorization model. When that doesn’t fit, we would end up with multiple authorization enforcements written in different languages with or without any adherence to any standards such as XACML or others. Imagine building few different or hundreds of products or services or micro services and you have to centrally manage all possible access policies. It’s definitely not a scalable solution in fast moving CI/CD world. Now imagine a way where every developers or products can externalize its authorization and we can modify authorization enforcement in a consistent manner? Imagine where developers can write their own implementation of how authorization should be enforced for their environment? Remember there is no one size fits all authorization policy. A policy that works for your environment does not work for my environment – for any number of reasons from Risk management to type of business applications. Open Policy Agent provides a consistent way to write authorization logic and expose it as REST API. Applications can easily integrate with OPA and can also write their own authroziation logics. Whether you are shipping products to customers or integrating a Product or Service into your environment, how awesome it would be to enforce your own authorization rules instead of changing your business process of who can gain access to what features. In this talk we will explore the benefits of Decentralized Authorization and how to use Open Policy Agent to achieve decentralized authorization. A closer look at few applications /integrations whether it is REST API /Micro Services, or Kubernetes to control various authorization policies as to who can deploy/what can you deploy. We will also look at how to build Integration tests to check our authorization policies.

At LifeOmic, we've built an automated change management system that allows production deployments without slow human approval. We maintain HIPAA and HITRUST compliance while still allowing continuous delivery. I'll show how to collect data from BitBucket, Jenkins, and security scan tools to ensure that the approved processes have been followed. You'll hear how fast production approval incentivizes developers to follow good practices, and become advocates for following the process instead of pushing against it. Automating process checks as a gate to deployments is a great framework for promoting the behavior you want in your organization. Don't give up on rapid feature delivery just because you work in a regulated industry.

Julian Berton Preventing a company from becoming the newest data breach statistic can be a daunting prospect. Especially working within a company that employs hundreds of engineers pushing code to production daily, it often feels like everything is on fire and the holy grail of producing a security inspired product is but a dim light growing further and further away. The same feeling is true for security aware engineers being pushed to develop products quickly but also expected to consider quality assurance, operations, security and the reliability of their application or service. To help reduce the bleeding and build more security aware applications at scale, a balance of firefighting, preventative initiatives, automation and "JIT" education is required. So strap yourself in while we take you on a journey through 4 years of security successes and epic failures: * Automation - Implementing a secure-by-default build system (Buildkite) that makes detecting vulnerable dependencies (Snyk), storing secrets (AWS Secrets Manager) and scanning Docker containers, an effortless process. * Prevention - Eradicate several classes of bugs by selecting secure architectural patterns and using automated scripts to detect operational misconfigurations like dangling DNS entries, open S3 buckets, secrets checked into source code and repositories that have been made accidentally public. * "JIT” Education - Changing a companies security culture with RFC's for security standards, security integrated PIR via bug bounty program reports, visibility through security maturity frameworks (BSIMM).

Rahul Kumar & Rupali Dash In the current era of blockchain technology, mining crypto currency is one of the biggest hit. The talk covers how the attackers use the insecure containers to mine crypto currency and earn million dollar profits. Cryptojacking activity surged to its peak in December 2017, when more than 8 million cryptojacking events were blocked by many intrusion detection companies. While there have seen a slight fall in activity in 2018, it is still at an elevated level, with total cryptojacking events blocked in July 2018 totalling just less than 5 million. The talk will cover how the mining activities has been done using browsers as well as cloud containers. We will also discuss how the cloud provides like amazon, azure and go are detecting such kind of activities and how minor misconfigurations leads to million dollar currency mining. The talk will also cover how 3rd party security providers like symantec and z-scalar and other intrusion detection system has configured signatures to block such kind of attacks. As well as from a sec-ops prospective what configuration checks should be done to prevent against such kind of attacks as well as detection of attacks. It will also cover some case studies and attack scenarios of mining Monero and the huge financial losses because of this attacks.

Cameron Townshend Today’s pace of innovation and need to out “innovate” competitors can often cause developers to bypass key portions of Gene Kim’s Three Ways of DevOps - specifically to never pass a known defect downstream and emphasize performance of the entire system. As we embrace movements like CI, CD and Devops to cut down on release cycles - and innovate faster, we as developers must also embrace the reality that the risk landscape is too complex to leave “security” to just those with security in their title. Traditional methods do not cut it anymore – it’s time for DevSecOps. Instinctively, we understand how critical this is. In Sonatype’s recent 2018 DevSecOps Community report, where 2,076 IT professionals were surveyed, 48% of respondents admitted that developers know application security is important, but they don’t have the time to spend on it. Done properly, DevSecOps practices shouldn’t interrupt the DevOps pipeline - but instead aid it - preventing costly rebuilds and build breaks, down the road. By creating automated governance and compliance guardrails that are embedded early and throughout the software development lifecycle, developers have transparent access to digital guardrails integrated within our native tools — an approach that ensures security is being built in without slowing us down. These instant feedback loops detailing good or bad components have been shown to increase developer productivity by as much as 48%. Over time, this approach ensures developers procure the best components from the best suppliers, while continuously tracking components across the entire lifecycle. Attendees of this session will walk away with: Real-world examples of how large and small companies are implementing DevSecOps practices in their own delivery pipelines, and increasing developer awareness to risks Key insights from 2,076 of their peers who participated in the 2018 DevSecOps community report - including where most mature DevOps practices are focusing their security efforts A walkthrough of how security principles have been embedded in a CICD pipeline and what standards for implementation are beginning to follow suite

Tilak T Web-Services are taking over the world. Rest-framework is accelerating this development, because of its ease and flexibility. Developers often use and develop REST-based applications because it's exciting to work with. But they forget about security which leads to compromised and exploited applications. For instance, in more recent security tests against Web Services that my team executed, we found that vulnerabilities like Insecure Deserialization, XML External Entities, Server-Side Template Injection and Authorization Flaws are quite prevalent. I have found some simple steps that engineering teams can take towards finding and fixing such vulnerabilities with Web Services. This talk is offering a holistic perspective on finding and fixing some uncommon flaws that will be replete with anecdotes and examples of secure and insecure code. I will also delve into automating SAST and DAST tools using Robot-Framework to identify such flaws in Web-Services.

Sharath Kumar Ramadas Serverless Technology (Functions as a Service) is fast becoming the next "big thing" in the world of distributed applications. Organizations are investing a great deal of resources in this technology as a force-multiplier, cost-saver and ops-simplification cure-all. Especially with widespread support from cloud vendors, this technology is going to only become more influential. However, like everything else, Serverless apps are subject to a wide variety of attack possibilities, ranging from attacks against access control tech like JWTs, to NoSQL Injection, to exploits against the apps themselves (deserialization, etc) escalating privileges to other cloud components. On the other hand GraphQL (API Query Language) is the natural companion to serverless apps, where traditional REST APIs are replaced with GraphQL to provide greater flexibility, greater query parameterization and speed. GraphQL is slowly negating the need for REST APIs from being developed. Combined with Serverless tech/Reactive Front-end frameworks, GraphQL is very powerful for distributed apps. However, GraphQL can be abused with a variety of attacks including but not limited to Injection Attacks, Nested Resource Exhaustion attacks, Authorization Flaws among others. This talk presents a red-team perspective of the various ways in which testers can discover and exploit serverless and/or GraphQL driven applications to compromise sensitive information, and gain a deeper foothold into database services, IAM services and other other cloud components. The talk will have some demos that will demonstrate practical attacks and attack possibilities against Serverless and GraphQL applications. The author will release an intentionally vulnerable Serverless and GraphQL app at the end of the talk for the benefit of the audience and the security community at large.

Nadira Bajrei IT Continuous Improvement and Knowledge Management at Bank Mandiri Tbk We all know that the Banking industry is highly regulated. But due to recent changing factors, we had to trigger something we call transformation. Two of the most important reasons why we need transformation are firstly digital disruption, a wave our industry is hard pushed to follow, and secondly the evolving customer expectation and competitive environment, which are impacting the way organisations are delivering value. We need a new way of working to help us stay relevant in the market. This session will focus on our journey as one of the biggest banks in Indonesia to do digital transformation into DevOps while maintaining security compliance requirements. I will elaborate on the main reason why we need transformation, our journey roadmap, the step by step adoption of CALMS Values in our organisation and how we faced challenges from internal and external site.

Liz Rice The latest Kubernetes version provides many security-related enhancements and controls, but it is far from being secure by default. Kubernetes is a complex orchestration platform with many different implementations, across multi-cloud/hybrid environments. Configuring it to comply with security best practices and specific security requires time and expertise that most organizations don’t possess. Aqua’s open source tools arm Kubernetes administrators and developers with an easy way to identify weaknesses in their deployments so that they can address those issues before they are exploited by attackers. During this presentation, we’ll review how these open source tools offer preventive security for Kubernetes: Kube-Bench: checks a Kubernetes cluster against 100+ checks documented in the CIS Kubernetes Benchmark. Kube-Hunter: conducts penetration tests against Kubernetes clusters that hunt for exploitable vulnerabilities and misconfiguration - both from outside the cluster as well as inside it (running as a pod)

COLIN DOMONEY The advent of DevOps and large scale automation of software construction and delivery has elevated the software supply chain – and its underpinning delivery pipeline – to mission critical status in any modern enterprise. The increased velocity of modern pipelines and the removal of manual checks and balances has meant that modern pipelines are potential single points of failure in the delivery of secure software. Automotive and consumer electronics industries have long understood the need for both provenance (understanding the origin of materials) and veracity (ensuring the integrity of their manufacturing processes) in their supply chains; this presentation will address threats to software supply chains and practical approaches to reducing the fragility of your supply chain. Several examples of software supply chain failures will be presented and deconstructed to understand the typical failure modes. At the most elementary level many pipelines are poorly constructed with low levels of repeatability and poor test coverage, in other organisations there is a lack of governance over the supply chain allowing careless or willingly negligent actors to subvert or bypass controls or testing within the pipeline. There is also no standard mechanism to ensure a ‘chain of custody’ within a pipeline due to a lack common interchange format between tools, or a standard manner to represent the steps within a pipeline build process. This presentation will cover approaches (using ‘people and process’) in enforcing governance within a supply chain by describing best practices used in large-scale AppSec programmes. Several emerging technology initiatives will be presented: Google’s Grafeas is a means to ensure vulnerability information is represented in a uniform manner across all steps of a pipeline process, while In-Toto is a project to formally enforce the integrity of a pipeline process. A reference secure pipeline will be presented demonstrating both tools working in symphony, along with standard open source and commercial AppSec tools. Finally the pipeline itself may become the Achille’s Heel in an organisation – many pipelines are not sufficiently hardened and are themselves open to attack by use of vulnerable components and their extensible nature, often along with very wide open permissions. Guidance will be given on hardening of typical pipelines, and a fully secured ephemeral Jenkins pipeline will be demonstrated. Benefits of this Session: The attendee will gain an increased awareness of the pivotal importance of the software supply chain, and gain an understanding of some common failure modes and weaknesses. Most importantly the attendee will come away with practical guidance on enforcing higher levels of governance on their supply chain without reducing delivery velocity, as well as how to harden the pipeline infrastructure itself.

Paweł Krawczyk Most network services and daemons now offer TLS transport protection and their managing certificates and TLS configuration for server farms may use more resources than actual configuration of these services. What if you could get rid of all this complexity and replace it by single transport protection protocol, securing all of the traffic between your servers trasparently and with single centralized key and configuration management? This will be a story of a successful implementation of IPSec protocols, largely and undeservedly forgotten in that purpose, for securing a farm of production cloud servers, with configuration centrally managed with Ansible.
