CCSW 2021: The ACM Cloud Computing Security Workshop
in conjunction with the ACM Conference on Computer and Communications Security (CCS)
November 15, 7am-10:40am, 5pm-8:50pm Korea time (GMT+9)
First Part: 5:00-8:40pm EST on Sunday 14th
Second Part: 3:00-6:50am EST on Monday 15th
Clouds and massive-scale computing infrastructures are starting to dominate computing and will likely continue to do so for the foreseeable future. Major cloud operators are now comprising millions of cores hosting substantial fractions of corporate and government IT infrastructure. CCSW is the world's premier forum bringing together researchers and practitioners in all security aspects of cloud-centric and outsourced computing, including:
Submissions due: August 8, 2021
Author notification: on/about September 4, 2021
Camera-ready: on/about September 20, 2021
Workshop: November 15, 7am-10:40am, 5pm-8:50pm Korea time (GMT+9) (First Part: 5:00-8:40pm EST on Sunday 14th, Second Part: 3:00-6:50am EST on Monday 15th)
The submissions window is closed. For any related concerns please contact us by email at email@example.com.
CCSW is soliciting full papers of up to 12 pages which will be judged based on the quality per page. Thus, shorter, high-quality papers are encouraged, and papers may be perceived as too long if they are repetitive or verbose. Submissions must be single PDF files, no more than 12 pages long in double-column ACM format (the sigconf template from https://www.acm.org/publications/proceedings-template, with a simpler version at https://github.com/acmccs/format), excluding the bibliography, well-marked appendices, and supplementary material. Note that reviewers are not required to read the appendices or any supplementary material. Authors should not change the font or the margins of the ACM format. Submissions not following the required format may be rejected without review. Submissions not meeting these guidelines risk rejection without consideration of their merits. Accepted papers will be published by the ACM Press and/or the ACM Digital Library.
Submissions must be anonymous, and authors should refer to their previous work in the third-person. Submissions must not substantially overlap with papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings. Each accepted paper must be presented by one registered author. Submissions not meeting these guidelines risk immediate rejection. For questions about these policies, please contact the chairs.
One best paper award will be presented during the workshop.
Proposals for panels are also solicited. The proposals are to be concise, up to 2 pages in length, describe the handled topics, name potential panelists and briefly scope the panel for CCSW. Disruptive and controversial panels are particularly encouraged. Please submit your panel proposals as a PDF by email at firstname.lastname@example.org.
Papers can be accessed at this link.

"Programmable Security in the Age of Software-Defined Infrastructure"
Today's network and computing infrastructure rests on inadequate foundations. An emerging, promising new foundation for computing is software-defined infrastructure (SDI), which offers a range of technologies including: compute, storage, and network virtualization; novel separation of concerns at the systems level; and new approaches to system and device management. As a representative example of SDI, software-defined networking (SDN) is a new networking paradigm that decouples the control logic from the closed and proprietary implementations of traditional network data plane infrastructure. SDN is now becoming the networking foundation for cloud/data-center, future Internet and 5G infrastructures. We argue that we should leverage software-defined infrastructure to design new methodologies and principles to make security programmable. In this talk, I will discuss some new opportunities as well as challenges in this new direction, and demonstrate with case studies from our recent research results. Our vision is that future security will be programmable thus more intelligent and powerful to secure a software-defined world.

"Security in a Cloud Bazaar"
While cloud computing is transforming society, today's public clouds are black boxes, implemented and operated by a single provider that makes all business and technology decisions. In 2013 we launched the Mass Open Cloud (MOC) with the vision of creating a production cloud that would enable innovation by a broad industry and research community. This open cloud has become a laboratory for cloud research and innovation, resulting in hundreds of publications, contributions to open source software, and collaborations between researchers, open source developers, and production operations staff. Recently we launched the Open Research Cloud Initiative (ORCI) to provide a framework to coordinate the bazaar of interrelated projects and initiatives that have evolved since 2013, including the Red Hat Collaboratory@BU, Open Cloud Testbed (OCT), New England Research Cloud (NERC), Northeast Storage Exchange (NESE), Operate First, and OpenInfra Labs. With its launch, the MOC inspired and enabled research in cloud security. For example, the Modular Approach to Cloud Security (MACS) SaTC NSF frontier project, launched in 2014, brought together cryptographers, operating system, database and computer architecture researchers from BU, MIT, UConn and NEU. This security research resulted in new open-source software and products that are today enabling new services in the ORCI bazaar. This talk will discuss the ORCI cloud bazaar, some of the security research and projects it inspired, and some exciting new collaborations happening now to make the cloud both open and secure.

"Data Sovereignty in the Cloud - Wishful Thinking or Reality?"
The idea of data sovereignty has been at the core of various research activities over the last years, especially in Europe. The topic gained additional traction through various regulations and initiatives such as the EU General Data Protection Regulation (GDPR), the European Cybersecurity Certification Scheme for Cloud Services (EUCS) and lastly, Gaia-X. While asserting digital control over your data is relatively easy in a closed ecosystem, such as your own on-premises or a community data space, it is infinitely more challenging in a public open ecosystem, such as the Cloud. On one hand, recent advantages in the field of confidential computing, such as the introduction of secure enclaves and encrypted virtual machine memory are promising new ways to enforce data sovereignty even in Cloud infrastructures. On the other hand, the mere existence of these techniques does not ensure an overall secure system, demonstrated by various flaws found in confidential computing techniques themselves, such as AMD SEV. So, the question remains if data sovereignty in the cloud is already reality or still wishful thinking? Keeping the requirements from initiatives such as Gaia-X and the EUCS in mind, this talk will explore what it means to achieve data sovereignty and security in the Cloud. It is important to understand, that it is not only necessary to implement appropriate security measures, but also (continuously) demonstrate the effectiveness of them. Therefore, this talk will show an overview of different technical means to leverage confidential computing for data sovereignty in the Cloud, especially using remote attestation and integrity verification. Furthermore, it will explore techniques to demonstrate the effectiveness of these measures with regards to regulation compliance. One such example is the MEDINA framework, which aims to continuously verify the requirements of EUCS and Gaia-X, both on the infrastructure as well as the application level in cloud systems.
