  Threat actors can be persistent, motivated and agile, and they leverage a diversified and extensive set of tactics, techniques, and procedures to attain their goals. In response to that, organizations establish threat intelligence programs to improve their defense capabilities and mitigate risk. Actionable threat intelligence is integrated into security information and event management systems (SIEM) forming a threat intelligence platform. A threat intelligence platform aggregates log data from multiple disparate sources by deploying numerous collection agents and provides centralized analysis and reporting of an organization's security events for identifying malicious activity. Sysmon logs is a data source that has received considerable attention for endpoint visibility. Approaches for threat detection using Sysmon have been proposed mainly focusing on search engines (NoSQL database systems). This paper presents a new automated threat assessment system that relies on the analysis of continuous incoming feeds of Sysmon logs. The system is based on a cyber threat intelligence ontology and analyses Sysmon logs to classify software in different threat levels and augment cyber defensive capabilities through situational awareness, prediction, and automated courses of action.

  This paper presents PS0, an ontological framework and a methodology for improving physical security and insider threat detection. PS0 can facilitate forensic data analysis and proactively mitigate insider threats by leveraging rule-based anomaly detection. In all too many cases, rule-based anomaly detection can detect employee deviations from organizational security policies. In addition, PS0 can be considered a security provenance solution because of its ability to fully reconstruct attack patterns. Provenance graphs can be further analyzed to identify deceptive actions and overcome analytical mistakes that can result in bad decision-making, such as false attribution. Moreover, the information can be used to enrich the available intelligence (about intrusion attempts) that can form use cases to detect and remediate limitations in the system, such as loosely-coupled provenance graphs that in many cases indicate weaknesses in the physical security architecture. Ultimately, validation of the framework through use cases demonstrates and proves that PS0 can improve an organization's security posture in terms of physical security and insider threat detection.

International Journal of Advanced Computer Science and Applications (IJACSA).  ISSN 2158-107X.  9(3), s 405- 414 . doi: 10.14569/IJACSA.2018.090354 Full text in Research Archive. Show summary

  The aim of this paper is to elucidate the implications of quantum computing in present cryptography and to introduce the reader to basic post-quantum algorithms. In particular the reader can delve into the following subjects: present cryptographic schemes (symmetric and asymmetric), differences between quantum and classical computing, challenges in quantum computing, quantum algorithms (Shor’s and Grover’s), public key encryption schemes affected, symmetric schemes affected, the impact on hash functions, and post quantum cryptography. Specifically, the section of Post-Quantum Cryptography deals with different quantum key distribution methods and mathematical-based solutions, such as the BB84 protocol, lattice-based cryptography, multivariate-based cryptography, hash-based signatures and code-based cryptography.

  Data protection legislation was originally defined for a context where personal information is mostly stored on centralized servers with limited connectivity and openness to 3rd party access. Currently, servers are connected to the Internet, where a large amount of personal information is continuously being exchanged as part of application transactions. This is very different from the original context of data protection regulation. Even though there are rather strict data protection laws in an increasing number of countries, it is in practice rather challenging to ensure an adequate protection for personal data that is communicated on-line. The enforcement of privacy legislation and policies therefore might require a technological basis, which is integrated with adequate amendments to the legal framework. This article describes a new approach called Privacy Policy Referencing, and outlines the technical and the complementary legal framework that needs to be established to support it.

  Stortingsmeldingen om IKT-sikkerhet: Et felles ansvar (2017) ble behandlet 10. april 2018. Et av de viktigste vedtakene som Stortinget fattet er at alle relevante ingeniør- og teknologiutdanninger skal ha informasjonssikkerhet inn i studiene. En oppfølgning av stortingsmeldingen var en revidert forskrift om rammeplan for ingeniørutdanning som ble vedtatt i mai 2018. Som følge av dette ble det opprettet en arbeidsgruppe for å utarbeide en strategi for hvordan Stortingets vedtaket bør settes ut i praksis, dvs. for å utarbeide en kompetansestrategi for IKT-sikkerhet. Denne artikkelen beskriver kort arbeidet som er gjort så langt, og planer for det videre arbeidet frem mot overlevering av rapporten om kompetansestrategien i mars 2020.
