PAUL SCHWARZENBERGER Access keys in GitHub, open security group rules, misconfigured Identity and Access Management roles, private SSL certificate keys kept in code repositories and open S3 buckets. Just some of the security issues which led to a journey towards automated compliance solutions for cloud infrastructure and applications. Paul describes a framework for Continuous Cloud Compliance, and demonstrates some of the techniques and tools he has used while working on cloud migration projects and operational cloud applications for both public and private sector organisations.

The development of advanced services that are the promise of smart cities are based on a connected infrastructure, devices (e.g., cars, IoT devices, etc.), and software systems. Therefore, the exchange of data among such components is a prerequisite that is based on the definition of common protocols and data formats that needs to be open to assure the availability in the long run. However, too many protocols and formats can create confusion and fragmentation that can produce the opposite effect making difficult the creation of a uniform architecture. This talk will explore the main protocols and data formats used in the context of the smart cities identifying the main characteristics and the overlaps.

How should IT architecture look like in the ages of Cloud and Devops? How do the changes and the technological evolution of the last years affect our systems and processes? Why is innovation and digitalization important? What means 'cloud-native', how should I build my solutions? To anwer these questions we will look at the "Big Five": Microservices and Containers, cloud and DevOps and finally BigData, IoT and last-but-not-least artificial intelligence.

According to service scale, there are hundreds or thousands of running containers in your service. Should we monitor each container by microscope or monitor each microservice by magnifier? This depends which granularity can help us find and solve the problems. In this sharing, I will introduce how to use cAdvisor, Icinga2, InfluxDB and Grafana to build a self-hosted monitoring system. In addition, I also discuss with how to embrace open source and share some practical experiences.

A successful API strategy requires a strong partnership between the business, IT, and security functions. Rather than as a hindrance, security increasingly is viewed as a business enabler, with CISOs and CSOs playing a critical role in implementing “guardrails” for safe, secure and compliant API services and security architectures free of unnecessary complexity. Ultimately, a secure API platform enables developers and DevOps to focus on innovation—by improving the mobile user experience and deploying apps in the cloud, with appropriate security controls built-in. In this webcast, Apigee’s Subra Kumaraswamy and Saba Software CSO Randy Barr will explore how CISOs and CSOs partner with IT and business leaders for a safe and secure journey to cloud, SaaS, and mobile services. Join to learn about: - The role of the security officer in helping IT and business meet objectives - How smart and secure API guardrails remove friction in consuming APIs while protecting sensitive data exposed via APIs. - Best practices that work for an API centric enterprise Download podcast: http://bit.ly/1B6h3TR

Bart van der Sloot joined FiberRing as Managing Director in April 2014, with the objectives to further grow and enhance the footprint, quality and business of FiberRing’s 2 Tbps global IP network, covering over 50 locations on 3 continents. From 1999 to 2013 Bart worked at Global Crossing (acquired by Level 3 in 2011), where he developed staffing, systems and business processes for Global Crossing’s European brand new sales team, built and coached a Wholesale Sales team to sign new telecom customers and grow revenues in various countries across Europe, led Global Crossing’s expansion into Central and Eastern Europe and established Level 3’s position in the Benelux broadcast market. Samer Abdel-Hafez joined the FiberRing network team in December 2013 as Network Design Engineer. Samer’s responsibilities within the team include planning capacity for the large traffic volume of FiberRing, arranging interconnections in new locations and markets, designing advanced ad-hoc solutions for the FiberRing network and customers and advise the Network support team on day to day issues. Abstract: FiberRing operates one of the largest content networks in the world, peaking at over 2 Tb/s. In order to facilitate troubleshooting, detect attacks and saving important data as router configurations, we implement a series of tools mostly implemented in house or open source. The key point of this presentation is to describe how FiberRing is using these tools for: monitoring: FiberRing makes extensive use of Opsview (Nagios) and NMIS. We utilise Opsview for alerts and reporting and NMIS for detailed traffic analysis. capacity planning: FiberRing choose PMACCT as netflow collector software and implemented an in house front-end solution that helps us locate strategic peering partners and explore ways to reduce the costs to deliver our content. DDOS attacks detection: As every large hosting provider, we are regularly target of DDoS attacks. We implement a set of linux boxes running running nfcapd to collect traffic flows with 1 minute/per host granularity. This gives us great flexibility and incredibly valuable data to quick detect attacks and take corrective actions. routers’ configuration backups: FiberRing is actively involved in the development of Oxidized, an innovative configuration backup tool which poses itself as rancid replacement.

Presenter: Antonio Alcocer, Big Data Architect at Stratio Telefonica is the incumbent telecommunications network operator in Spain and the fourth one in capitalisation in the world. Cyber security is one of our most successful businesses worldwide. We provide monitoring and protecting clients from attacks. We analyze millions of data from multiple sources including social media, DNS records, and underground internet, to generate alerts and security reports for our clients. This use case required a Big Data component capable of processing the data and extract its information in real-time; warnings and alerts are time-sensitive in order to deal efficiently with security attacks. Our original architecture was the typical one used for data fusion systems. It included several collectors, a processing layer based on legacy systems, and a data store. The initial setup included a MongoDB database and an ad-hoc application. This solution however proved to be unfit for the specific purpose of dispatching alerts. We proposed to use Cassandra and Spark instead. This approach did manage to fulfill our original specifications as intended. Our talk will explain the reasons why we migrated the architecture and how the adopted solution based on Spark and Cassandra solved our problem.

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.

Mitun Zavery Senior Engineer at Sonatype Bad actors have recognized the power of open source and are now beginning to create their own attack opportunities. This new form of assault, where OSS project credentials are compromised and malicious code is intentionally injected into open source libraries, allows hackers to poison the well. In this session, Mitun will explain how both security and developers must work together to stop this trend. Or, risk losing the entire open source ecosystem. Analyze, and detail, the events leading to today’s “all-out” attack on the OSS industry Define what the future of open source looks like in today’s new normal Outline how developers can step into the role of security, to protect themselves, and the millions of people depending on them

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.

Matt Lavin Software Architect at LifeOmic It's possible to have rapid feature delivery and happy developers without sacrificing high security and compliance. 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)

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.

PETKO D. PETKOV Thanks to the DevSecOps philosophy a growing number of organisations around the world are ensuring their businesses are set up with the security in mind from the get-go. DevSecOps is taking the world by storm. This talk is about how to introduce DevSecOps in your organisation with ready-made, zero-cost, open source templates accessible to everyone. The talk will introduce the OpenDevSecOps project and show many practical examples of how to easily deploy security testing infrastructure on top of existing and well-established development tools.

MIKE SHEMA Effective appsec emerges from DevSecOps tactics like feedback loops, automation, and the flexibility to respond to situations quickly. These tactics emphasize process and tools, sometimes neglecting the knowledge and skills of working with others to build and maintain apps. And the solutions they strive for don’t always catch the importance of how different users can have different threat models. On the technology side of appsec we have clouds, top 10 lists, and tools. But we haven’t built up equivalent resources, references, or models for the people we build apps with and who we build them for. This presentation dives into specific techniques and references for working with people and building threat models that go beyond basic technical concerns. Tabletop role-playing games are a great model for understanding and building skills that are important to DevSecOps teams. They encourage communication, collaboration, and the achievement of shared goals. And they also face the same challenges in solving conflicts, avoiding derailing behaviors, and ensuring everyone participates. Come discover how RPGs can positively influence your security teams. Security is an integral part of DevSecOps. And, yes, it’s made of people.
