  2. 1. Advancing Automation in Digital Forensic Investigations

    Author : Irvin Homem; Panagiotis Papapetrou; Fredrik Blix; Indre Žliobaitė; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Digital Forensics; Machine Learning; Computer Forensics; Network Forensics; Predictive Modelling; Distributed Systems; Mobile Devices; Mobile Forensics; Memory Forensics; Android; Semantic Web; Hypervisors; Virtualization; Remote Acquisition; Evidence Analysis; Correlation; P2P; Bittorrent; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : Digital Forensics is used to aid traditional preventive security mechanisms when they fail to curtail sophisticated and stealthy cybercrime events. The Digital Forensic Investigation process is largely manual in nature, or at best quasi-automated, requiring a highly skilled labour force and involving a sizeable time investment. READ MORE

  4. 2. Accelerating Distributed Storage in Heterogeneous Settings

    Author : Waleed Reda; Dejan Kostic; Peter Van Roy; Marco Chiesa; Adam Morrison; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed storage; File systems; Hardware offload; Persistent memory; Distribuerad lagring; Dilsystem; Maskinvaruavlastning; Beständigt minne; Computer Science; Datalogi;

    Abstract : Heterogeneity in cloud environments is a fact of life—from workload skews and network path changes, to the diversity of server hardware components, these are all factors that impact the performance of distributed storage. In this dissertation, we identify that heterogeneity can in fact be one of the primary causes of service degradation for storage systems. READ MORE

  5. 3. Vulnerability Analysis for Critical Infrastructures

    Author : Yuning Jiang; Yacine Atif; Jianguo Ding; Manfred A. Jeusfeld; Birgitta Lindström; Christoffer Brax; Sokratis Katsikas; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; critical infrastructure cybersecurity; vulnerability assessment; vulnerability quantification; computational intelligence in cybersecurity; cyber-physical system; INF303 Informationssäkerhet; INF303 Information Security; INF301 Data Science; INF301 Data Science; Distribuerade realtidssystem DRTS ; Distributed Real-Time Systems;

    Abstract : The rapid advances in information and communication technology enable a shift from diverse systems empowered mainly by either hardware or software to cyber-physical systems (CPSs) that are driving Critical infrastructures (CIs), such as energy and manufacturing systems. However, alongside the expected enhancements in efficiency and reliability, the induced connectivity exposes these CIs to cyberattacks exemplified by Stuxnet and WannaCry ransomware cyber incidents.

  6. 4. Compile-time Safety and Runtime Performance in Programming Frameworks for Distributed Systems

    Author : Lars Kroll; Seif Haridi; Jim Dowling; Peter Van Roy; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distributed systems; distributed computing; programming systems; programming languages; computer science; domain specific languages; message-passing; actor model; component model; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Distributed Systems, that is systems that must tolerate partial failures while exploiting parallelism, are a fundamental part of the software landscape today. Yet, their development and design still pose many challenges to developers when it comes to reliability and performance, and these challenges often have a negative impact on developer productivity.
