On coordinated checkpointing in distributed systems

Coordinated checkpointing simplifies failure recovery and eliminates domino effects in case of failures by preserving a consistent global checkpoint on stable storage. However, the approach suffers from high overhead associated with the che...

Distributed Systems and Networks

This book provides the student with comprehensive coverage of both networks and system architecture. It aims to introduce the most widely used networking protocols and distributed systems, covering recent developments in distributed process...

The Chubby lock service for loosely-coupled distributed systems

We describe our experiences with the Chubby lock service, which is intended to provide coarse-grained locking as well as reliable (though low-volume) storage for a loosely-coupled distributed system. Chubby provides an interface much like a...

DISTRIBUTED SYSTEM-A TOOL FOR BUILDING DEPENDABLE DISTRIBUTED SYSTEM

Physically, a Distributed System consists of a set of processors, with a collection of local storage mechanisms associated with each processor. A processor is able to execute programs that access and manipulate the local storage, where the ...

Distributed Systems

When we connect several computers in a network to jointly process large amounts of data, such a computing system is commonly referred to as a “distributed system”. From a technical standpoint the key difference between a distributed system ...

Developing a Self-Reflection Tool to Assess Schools’ Openness

In 2015, the EU Educational Policy document “Science Education for Responsible Citizenship” introduced the concept of Open Schooling as a promising approach to transform schools into innovation hubs within their local communities. In an ope...

Checkpointing and rollback-recovery for distributed systems

We consider the problem of bringing a distributed system to a consistent state after transient failures. We address the two components of this problem by describing a distributed algorithm to create consistent checkpoints, as well as a roll...

The LOCUS Distributed System Architecture

LOCUS, a distributed version of the popular operating system Unix, provides an excellent solution. It makes a collection of computers, whether they are workstations or mainframes, as easy to use as a single computer by providing a set of su...

Caching Hints in Distributed Systems

Caching reduces the average cost of retrieving data by amortizing the lookup cost over several references to the data. Problems with maintaining strong cache consistency in a distributed system can be avoided by treating cached information ...

Fault-tolerant clock synchronization in distributed systems

Existing fault-tolerant clock synchronization algorithms are compared and contrasted. These include the following: software synchronization algorithms, such as convergence-averaging, convergence-nonaveraging, and consistency algorithms, as ...

Structure and Encapsulation in Distributed Systems: the Proxy Principle

We present a novel view of the structuring of distributed systems, and a few examples of its utilization in an object-oriented context. In a distributed system, the structure of a service or subsystem may be complex, being implemented as a ...

E-administration, cybersecurity and municipalities – the challenges of cybersecurity issues for the municipalities in Hungary

Today, the digital revolution has also caught up with the administration.The digitalisation of the (public) administration has strong links to the security issues.Digitalisation could be interpreted as one of the tools for the good governan...

Cybersecurity

CybersecurityNowadays, the Internet is integrated into society both through social interaction and business transactions, so the need for data protection and security has become increasingly important.In addition, not only computers, but al...

Cybersecurity

Cybersecurity is not just making lede in news but is also attracting more attention than ever before among businesses, industries, academicians, and the common users. As the adversaries flourish the frequency of cyberattacks have increased ...

Cybersecurity

In today’s hyperconnected world, digital threats lurk in every corner of cyberspace. This comprehensive guide equips you with essential knowledge to identify, mitigate, and counter cyber threats, navigating the increasingly dangerous digita...

Blockchain for secure and decentralized artificial intelligence in cybersecurity: A comprehensive review

As the usage of artificial intelligence (AI) grows within the field of cybersecurity, so too does the demand for secure and decentralized AI systems to protect against potential cyber threats. Blockchain technology (BT) has emerged as the i...

Cybersecurity

Laboratory digitization can dramatically improve automation, quality control, and data analysis, reduce human error, and ensure process reproducibility. However, cybersecurity threats can compromise sensitive data and disrupt laboratory ope...

A Game-theoretic Taxonomy and Survey of Defensive Deception for Cybersecurity and Privacy

Cyberattacks on both databases and critical infrastructure have threatened public and private sectors. Ubiquitous tracking and wearable computing have infringed upon privacy. Advocates and engineers have recently proposed using defensive de...

Accountants, Cybersecurity Isn't Just for “Techies”: Incorporating Cybersecurity into the Accounting Curriculum

ABSTRACT In today's business world, it is essential that accountants be concerned about cybersecurity in their organizations and in the work they perform. Despite increasing importance as well as regulatory and professional emphasis, most a...
