Preface: A hardware prefetcher is a data prefetching technique implemented as a hardware component in a processor, aimed at improving performance by fetching data before it is actually needed. Let’s take a closer look at prefetching. And speculate what kind of prefetching will approach this discussion. Background: A research paper titled ‘ShadowLoad: Injecting State into…

Preface: When artificial intelligence gains enough intelligence, do you know what it will say if it knows that software or applications developed by humans have vulnerabilities? He would say “Fxxx”! Background: Docker Engine is the fundamental containerization engine that runs on servers and manages containers, while Docker Desktop is a developer-focused tool that includes Docker…

Preface: If successful, a path traversal attack may result in the following risks: Unauthorized data access: An attacker can gain access to sensitive files, such as configuration files, system files, or source code, which may include Credentials, application code and data, and sensitive operating system files. Background: NVIDIA NeMo™ is an end-to-end platform for developing…

Preface: Examples of side channel attacks include timing attacks, cache-based attacks, and network traffic analysis. Mitigating side channel attacks involves implementing secure coding practices, employing cryptographic algorithms resistant to side channels, and minimizing timing differences. Background: Cache side channel attacks can infer the secret information processed by the victim by measuring the victim’s cache usage…

Preface: OCFS2 is a file system. It allows users to store and retrieve data. The data is stored in files that are organized in a hierarchical directory tree. It is a POSIX compliant file system that supports the standard interfaces and the behavioral semantics as spelled out by that specification. Background: OCFS2 is a useful…
