Assessment of Cyber Security risks : A Smart Terminal Process
2023
In Finland, the connections to global maritime transportation logistics systems are an essential part of the national critical infrastructure. As a part of maritime logistics systems, the port's operations are important elements for global maritime traffic and the transportation supply chain. Digitalization of seaport services makes it possible to increase the efficiency of terminal systems in the logistic processes. At the same time, port logistic processes can notably reduce its CO2 emissions by optimizing port operations. The improvement of port processes relies very much on the development of Information and Communication Technology (ICT) and Industrial Control Systems (ICS) or Operatio…
"Minä poltan koko kaupungin!" Elämää 1800-luvun suomalaisessa satamakaupungissa erään merimiehen vaimon näkökulmasta.
2017
Kesäkuun viimeisenä yönä 1837 29-vuotias merimiehen vaimo Maria Lindgren hoiperteli öisen Porin kaduilla vahvassa humalassa. Yövartija Petter Olinin pysäyttäessä Marian tämä joutui pois tolaltaan ja huusi Olinille: ”Minä poltan koko kaupungin!” Olin ei nähnyt muuta vaihtoehtoa kuin viedä arvaamattomasti käyttäytyvä nainen kaupunginvankilaan, missä tämän kerrottiin riehuneen koko yön. peerReviewed
Cybersecurity Attacks on Software Logic and Error Handling Within AIS Implementations: A Systematic Testing of Resilience
2022
To increase situational awareness of maritime vessels and other entities and to enable their exchange of various information, the International Maritime Organization mandated the use of the Automatic Identification System (AIS) in 2004. The AIS is a self-reporting system that uses the VHF radio link. However, any radio-based self-reporting system is prone to forgery, especially in situations where authentication of the message is not designed into the architecture. As AIS was designed in the 1990s when cyberattacks were in their infancy, it does not implement authentication or encryption; thus, it can be seen as fundamentally vulnerable against modern-day cyberattacks. This paper demonstrat…
Stakeholder involvement in developing LNG as a ship fuel in the Baltic Sea region
2015
New environmental regulations require the shipping industry to reduce its sulphur emissions. The currently most environmentally friendly alternative for ship owners to comply with the regulations is the switch to LNG fuelled vessels which however also requires port developers to invest in the supply of LNG. In order to successfully implement the creation of an LNG infrastructure, various challenges have to be overcome. This study looks at the challenges of LNG as a ship fuel from a stakeholder perspective by conducting a port screening with the aim to assess the current development status of LNG projects and the drivers and impediments behind it. Furthermore, a qualitative research with exp…
Cyber Threat Analysis in Smart Terminal Systems
2023
Cyber threats create significant factors that challenge traditional threat prevention mechanisms in harbor areas and port terminals. It has been recognized that understanding security functionalities in the harbor area is based on a more traditional experience of what it requires. It is not enough that the maritime and harbor ecosystem repeats only physical security service routines regarding random checks of passengers and vehicles and customs functions on cargo and passenger transportation. Smart environments and infrastructures are widely expanded in urban areas and create more challenges if old practices are combined with new technologies and functionalities. Traditional threats have ch…
Sisävesien mikrotonnisto : pienet höyrylaivat Suomen ja erityisesti Kainuun sisävesiliikenteessä 1870-luvulta 1960-luvulle
2016
The significance in Finland of shipping on inland waterways has been great. This is due to the topography of the country with its many lakes and to the fact that the vast waterways in their natural state were easily navigable. The construction of canals resulted in even more extensive interconnected inland waterways. This study explores the tasks of the steamships plying these internal waterways, their numbers and significance, and also changes and the reasons for these between different inland waterways, as regards different types of vessels and shipowners in the period from the 1870s to the 1960s. Special attention is paid to steamships smaller than 19 net register tons. This limit was ch…
