Dynamic information flow tracking

WebAbstract: Dynamic information-flow tracking (DIFT) is useful for enforcing security policies, but rarely used in practice, as it can slow down a program by an order of magnitude. Static program analyses can be used to prove safe execution states and elide unnecessary DIFT monitors, but the performance improvement from these analyses is … WebFlow Tracking (IFT) is a widely used method in offline threat analysis after the occurrence of an attack to identify spurious information flows generated by untrustworthy I/O channels [5], [20].

A Game-Theoretic Approach for Dynamic Information Flow Tracking …

WebSecurity for Internet-of-Things devices is an increasingly critical aspect of computer architecture, with implications that spread across a wide range of domains. We present the design and implementation of a hardware dynamic information flow tracking (DIFT) architecture for RISC-V processor cores. Our approach exhibits the following features at … WebApr 27, 2024 · Information Flow Tracking. In order to restrict hardware timing channels and counterfeit input channels, dynamic information flow tracking is performed (Suh et al., 2004; Tiwari et al., 2009; Oberg et al., 2010; Ardeshiricham et al., 2024, 2024; Qin et al., 2024). Preventing these timing channels helps in restricting software-based attacks. philippine army female soldiers https://alistsecurityinc.com

WebJul 8, 2024 · Dynamic taint analysis (DTA) is widely used by various applications to track information flow during runtime execution. Existing DTA techniques use rule-based taint-propagation, which is neither accurate (i.e., high false positive) nor efficient (i.e., large runtime overhead). WebInformation flows consist of data and control commands that dictate how data is propagated between different system entities (e.g., instances of a computer program, files, network sockets) [7], [8].

Web2.1 Dynamic Information Flow Analysis Dynamic information flow tracking (DIFT) identifies the flow of data between two program locations. In taint analysis, it is often referred to as (taint) sources and (taint) sinks. For example, taint sources can be external inputs (e.g., network sockets, file reads, and user inputs), while taint sinks can be
