Visible to the public TWC: TTP Option: Small: Collaborative: SRN: On Establishing Secure and Resilient Networking Services

Almost every organization depends on cloud-based services. The backend of cloud-based services are designed for multiple tenants and reside in data centers spread across multiple physical locations. Network security and security management are major hurdles in such a complex, shared environment. This research investigates mitigating the security challenges by taking a moving target defense (MTD) approach.

Visible to the public TWC: Small: Communication under Adversarial Attacks in Complex Networks - Fundamental Limits and Secure Coding Strategies

Today's world is highly dependent on the integrity of communication systems as the Internet, WiFi, or cellular networks. As networks become more pervasive, they are increasingly being used for communication and storage of critical as well as sensitive data and therefore impose more stringent demands on reliability and security, which must be maintained even under extreme settings such as partial power failures, natural disasters, or, most importantly, adversarial attacks.

Visible to the public EAGER: Toward Automated Integration of Moving Target Defense Techniques

Moving Target defense (MTD) is a new Cybersecurity paradigm for deterring and disturbing attacks proactively in order to counter the ?asymmetry? phenomena in cyber warfare. A number of moving target techniques have been recently proposed to inverse this asymmetry by randomizing systems? attributes (e.g., configuration) and exhibiting non-determinism to attackers. However, due to potential inter-dependency between various MTD mechanisms, an ad hoc combination of MTD techniques can cause profoundly detrimental effect on security, performance and the operational integrity of the system.

Visible to the public TWC: Small: Collaborative: Multipath TCP Side Channel Vulnerabilities and Defenses

The objective of this project is to understand and strengthen the security of Multipath TCP (MPTCP) - an IETF standardized suite of TCP extensions that allow one MPTCP connection, consisting of multiple sub-connections between two hosts, to use multiple paths simultaneously. Even though MPTCP has been gaining momentum in being widely deployed, its security is yet to be well understood. The project is expected to raise awareness of MPTCP security and ultimately yield a foundation for MPTCP security.

Visible to the public TWC: TTP Option: Small: Collaborative: Detecting and Characterizing Internet Traffic Interception Based on BGP Hijacking

Recent reports have highlighted incidents of massive Internet traffic interception executed by re-routing Border Gateway Protocol (BGP) paths across the globe (affecting banks, governments, entire network service providers, etc.). The potential impact of these attacks can range from massive eavesdropping to identity-spoofing or selective content modification. In addition, executing such attacks does not require access or proximity to the affected links and networks, posing increasing risks to national security.

Visible to the public TWC: TTP Option: Small: Differential Introspective Side Channels --- Discovery, Analysis, and Defense

Side channels in the security domain are known to be challenging to discover and eliminate systematically. Nevertheless, they can lead to a variety of stealthy attacks seriously compromising cybersecurity. This work focuses on an important class of side channels that are fundamental to the operations of networked systems.

Visible to the public TTP: Medium: Detection and Analysis of Large-Scale Internet Infrastructure Outages

Despite the Internet's status as critical infrastructure, there is little scientific instrumentation dedicated to monitoring global Internet behavior. In particular, we have no rigorous framework for measuring, analyzing, or quantifying the impact of network outages, filtering, or other abnormal connectivity dynamics on a global scale.

Visible to the public TWC: Phase: Medium: Collaborative Proposal: Understanding and Exploiting Parallelism in Deep Packet Inspection on Concurrent Architectures

Deep packet inspection (DPI) is a crucial tool for protecting networks from emerging and sophisticated attacks. However, it is becoming increasingly difficult to implement DPI effectively due to the rising need for more complex analysis, combined with the relentless growth in the volume of network traffic that these systems must inspect. To address this challenge, future DPI technologies must exploit the power of emerging highly concurrent multi- and many-core platforms.

Visible to the public TWC: Medium: Collaborative: Towards Securing Coupled Financial and Power Systems in the Next Generation Smart Grid

For nearly 40 years, the United States has faced a critical problem: increasing demand for energy has outstripped the ability of the systems and markets that supply power. Today, a variety of promising new technologies offer a solution to this problem. Clean, renewable power generation, such as solar and wind are increasingly available. Hybrid and plug-in electric vehicles offer greater energy efficiency in transportation.
