SWOT-analyysin soveltaminen yrityksen kyberturvallisuuden tilannekuvan muodostamiseen : Cyber Trust/CIRP-raportti : tutkimusmenetelmän kuvaus 2017

2018

Modernin yhteiskunnan toiminta perustuu useiden kriittisten infrastruktuurien yhteistoimintaan. Niiden keskinäinen toimintakyky riippuu yhä enemmän luottamuksesta infrastruktuuriin kuuluvien organisaatioiden toimintakykyyn kybertoimintaympäristössä, jonka riskejä digitaalisen maailman uhkakuvat jatkuvasti kasvattavat. SWOT-analyysi on tärkeä väline analysoitaessa organisaation toimintakykyä ja sen toimintaympäristöä kokonaisuutena. Se on nelikenttämenetelmä, jota käytetään yleisesti tilannekuvan muodostamiseen laadittaessa yrityksen strategioita, sekä oppimisen tai ongelmien tunnistamisessa, arvioinnissa ja toimintaprosessien kehittämisessä. SWOTanalyysin kohteena voi olla jonkin yrityksen …

How Are Situation Picture, Situation Awareness, and Situation Understanding Discussed in Recent Scholarly Literature?

2019

There are several different definitions of situation awareness. However, all of them have in common is knowing and understanding of what is happening, an understanding of future changes or problems, and the prediction of the future situation and the decisions to be made on its basis. Situation picture and Situation Awareness are narrow. Situation understanding of the situation is the understanding of the decision-makers and their assistants about what has happened, the circumstances that have affected them, the goals of the different parties and the possible development options of the events needed to make decisions on a particular issue or subject. The results of this study indicate that t…

Cyber warfare : the game changer in the battlespace

2022

A recent development in warfare has been the integration of Electronic Warfare (EW), Information Warfare (IW) and Cyber Warfare (CW) systems designed to generate non-kinetic effects in battle space together with the traditional use of kinetic weapons. These new capacities of armed forces create new possibilities to achieve the goals of war. These advanced and new capabilities form a whole new non-kinetic environment in which they have become a game changer in battle space. This article focuses on describing cyber warfare and the first experiences of the war in Ukraine. nonPeerReviewed

Leveraging the benefits of big data with fast data for effective and efficient cybersecurity analytics systems : A robust optimisation approach

2020

In recent times, major cybersecurity breaches and cyber fraud within the public and private sectors are making international headlines. Majority of organisations are facing cybersecurity adversity and advanced threats. On the one hand, we have asynchronous cybersecurity practices, many standards and frameworks to consider while on the other hand, we have to deal and secure our organisations against cyber-criminals, organised hacktivists, insider threats, hackers and nation-states with malafide intentions. The Center for Cyber Safety and Education's Global Information Security Workforce Study (GISWS) confirms that globally we are not only loosing but also backpedalling against threats and ri…

Data Mining for the Security of Cyber Physical Systems Using Deep-Learning Methods

2022

Cyber Physical Systems (CPSs) have become widely popular in recent years, and their applicability have been growing exponentially. A CPS is an advanced system that incorporates a computation unit along with a hardware unit, allowing for computing processes to interact with the physical world. However, this increased usage has also led to the security concerns in them, as they allow potential attack vendors to exploit the possibilities of committing misconduct for their own benefit. It is of paramount importance that these systems have comprehensive security mechanisms to mitigate these security threats. A typical attack vector for a CPS is malicious data supplied by compromised sensors that…

Where Cyber Meets the Electromagnetic Spectrum

2019

Cyber linked with Information Technology, computers and the internet are the most commonly understood potential threats that everybody is aware of nowadays. In the case of National Cyber Strategy most efforts are given to these potential battlefields and threats. But is it enough to stay with these paradigms? Cyber warfare will look for utmost effects for chaos and misalignment of economy and therefore we cannot exclude the facts, that there is a potential threat also possible in the cut volumes between the information technology, the electromagnetic spectrum and its linked infrastructure and processes. We understand the technology for mobile telecommunications and data transfer, as the pro…

Avoimen lähdekoodin alustojen sopivuus älykotiin

2017

Internet of Things kasvaa jatkuvasti ja sen eräs suurimmista sovelluskohteista on älykoti. IoT:n ongelmana on kuitenkin ollut keskimäärin erittäin huono tietoturva ja tämä on heijastunut myös älykoteihin esimerkiksi hakkeroituina kameroina ja itkuhälyttiminä. Toinen, älykodissa erityisen suuri ongelma on kerätyn tiedon yksityisyys. Tässä tutkielmassa kartoitetaan, kuinka hyvin avoimen lähdekoodin ohjelmistot soveltuvat toimivan ja turvallisen älykodin toteuttamiseen. Turvallisuuden osalta painopisteenä on erityisesti etäyhteys. Tutkimus toteutettiin konstruktiivisena tutkimuksena. Se ei käsittele yksittäisiä ohjelmistoja kovin syvällisesti, vaan sen tarkoituksena oli saada kattavahko yleisk…

Arm security alternatives

2019

Many real-world scenarios such as protecting DRM, online payments and usage in NFC payments in embedded devices require a trustworthy “trusted execution environment” (TEE) platform. The TEE should run on the ARM architecture. That is popular in embedded devices. Furthermore, past experience has proved that such TEE platform should be available in source code form. Without the source code 3rd parties and user cannot be conducted code review audit. Lack of review put doubt on the system as a trustworthy environment. The popular Android OS supports various TEE implementations. Each TEE OS implementation has its own unique way of deploying trusted applications(trustlets) and its own distinct fe…

Beyond economic and financial analyses : A revelatory study of IT security investment decision-making process

2022

Information Technology (IT) security breaches and the extent of damage they may cause to an organization are inherently uncertain. Therefore, managers’ decisions about whether to make IT security investment (ITSI) and how much, depend upon a subjective assessment of the economic value of the investment and the likelihood of the damage to the organization. When managers delay or fail to decide on whether and how much to invest in IT security, it can make organizations vulnerable to operational and strategic perils. Based upon interviews, document reviews, and observations in three organizations in Finland that made ITSI decisions to acquire a secure email application system, we examined the …
