Protecting Data with Short-Lived Encryption Keys and Hardware Root of TrustDan Griffin
The US National Security Agency has been public about the inevitability of mobile computing and the need to support cloud-based service use for secret projects. General Alexander, head of the NSA, recently spoke of using smartphones as ID cards on classified networks.
And yet, mobile devices have a poor security track record, both as data repositories and as sources of trustworthy identity information. Cloud services are no better: current security features are oriented toward compliance and not toward real protection.
What if we could provide a strong link between mobile device identity, integrity, and the lifecycle of data retrieved from the cloud using only the hardware shipped with modern smartphones and tablets?
The good news is that we can do that with the trusted execution environment (TEE) features of the common system on a chip (SOC) mobile processor architectures using 'measurement-bound' encryption. This presentation describes how data can be encrypted to a specific device, how decryption is no longer possible when the device is compromised, and where the weaknesses are. I demonstrate measurement-bound encryption in action. I also announce the release of an open-source tool that implements it as well as a paper that describes the techniques for time-bound keys.
This is likely the very same way that NSA will be protecting the smartphones that will be used for classified information retrieval. Learn how your government plans to keep its own secrets and how you can protect yours.

SANSFIRE18: War Stories on Using Automated Threat Intelligence for DefenseJohn Bambenek
Between limited resources and a lack of trained professionals on one hand and the increasing quantity and quality of attacks on the other, securing enterprises and responding to incidents has placed defenders on the losing end of a digital arms race. Even managing the amounts of threat data and open-source intelligence has become a challenge.
This talk will cover the possibilities and perils of integrating all the various sources of threat intelligence data to protect an organization. With all the various open-source and paid-source data, simply dumping it all into a firewall or DNS RPZ zone can be problematic. What to do about compromised websites or shared hosting environments? What about DGA domains that use full words and may collide with actual innocent websites? What about how to handle threat data that is lacking in context to make appropriate decisions on its validity and accuracy? This talk will present several case studies in how these problems can be tackled and how using multi-domain analysis can help reduce the risk and maximize the value of automated protection using these types of data.

MongoDB .local London 2019: New Encryption Capabilities in MongoDB 4.2: A Dee...MongoDB
Many applications with high-sensitivity workloads require enhanced technical options to control and limit access to confidential and regulated data. In some cases, system requirements or compliance obligations dictate a separation of duties for staff operating the database and those who maintain the application layer. In cloud-hosted environments, certain data are sometimes deemed too sensitive to store on third-party infrastructure. This is a common pain for system architects in the healthcare, finance, and consumer tech sectors — the benefits of managed, easily expanded compute and storage have been considered unavailable because of data confidentiality and privacy concerns.
This session will take a deep dive into new security capabilities in MongoDB 4.2 that address these scenarios, by enabling native client-side field-level encryption, using customer-managed keys. We will review how confidential data can be securely stored and easily accessed by applications running on MongoDB. Common query design patterns will be presented, with example code demonstrating strong end-to-end encryption in Atlas or on-premise. Implications for developers and others designing systems in regulated environments will be discussed, followed by a Q&A with senior MongoDB security engineers.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

• Chief Security Officer / CIO has power to decide
• Product features come after security features
3. ionGrid
• Solve BYOD for
file access
• Secure container
• Integrates with
current
infrastructure
5. Data in movement (cont)
• Provisioning
• Enables end-to-end encryption
• Improves security against “man in the middle attack”
• Secure channel in AMQP protocol
• Pro : AMQP instead of HTTPS gives stronger encryption
• Cons : very hard to work with…
• Real use case
• Pretty much everything…
7. Data at rest
• Encrypt data
• Much harder to access the data against a dumping attack
• Server gives the key every time authentication is correct
• Multiple factor authentication (password, RSA SecureID,
etc…)
• Offline authentication
• Encrypt master key using password
• User can retrieve its key with password
8. Security policies
• Classic RWX (Read, Write, Execute)
• Pros: Access data, modify them, etc…
• Cons: Very hard to express the business needs
• “Can I … ?” policies (ie: can login)
• Pros: Much better for business needs
• Cons: Requires a lot of maintenance
• How can I handle a lot of business rules ?
• Access data only during the day / at a location
• Specify policies per file / folder / user
9. Security policies (cont)
• Empower your customer with its own security
policies!
• Define “Can I … ?” policies in client
• Policy engine is defined in JavaScript
• Let the company code and define its own
rules or use simple true/false checkboxes
• Code snippet can be defined per file / user
• Code is shipped to the device
• Works offline
• Works in the future

• Simple cases:
• Device stolen or lost
• Employee quits or is fired
• Device exits location
• Active attacks
• Faraday bag
• Forensic attack
TIME-BOMB EVERYTHING!
11. Real use cases
• JP Morgan

13. And now…
• Which use case around secure
messaging have you heard about ?
• What security problem should we try to
solve ?
