Based on numerous high level concerns that the cyber threat is expected to increase, as well as the already documented uses of cyber warfare, it is necessary to ensure our naval ships are hardened against such attacks. In doing so, an influence net model was designed to discover the likelihood of a successful cyber attack. However, first it was necessary to establish what the best mitigation tools are in defense of cyber attack methods. In order to do so, an expert opinion survey was designed and completed by individuals currently working in the field of network security. In combination with the expert opinion surveys and in looking at research and established security techniques it should become apparent whether or not ships are taking all the required steps to best secure themselves against an attack. Though the initial model was designed around a theoretical Naval Station Everett ship, with modification the model can be utilized for any naval asset throughout the United States and the risk for each particular U.S. asset can be evaluated. Additionally, this tool can also facilitate security funding as well as establishing a means of prioritizing the tools for protection if the network needs to be hastily re-established after an attack. Ultimately, the protection of a ship’s computer networks against cyber terrorist threats is fundamental in ensuring continued effective command and control and ultimately the security of this nation.

The increasing pervasiveness of social media has been matched by growing concerns regarding their potential impact on democracy and public debate. While some theorists have claimed that ICTs and social media would bring about a new independent public sphere and increase exposure to political divergence, others have warned that they would lead to polarization, through the formation of echo chambers. The issue of social media echo chambers is both crucial and widely debated. This article attempts to provide a comprehensive account of the scientific literature on this issue, highlighting the different approaches, their similarities, differences, benefits and drawbacks, and offering a consolidated and critical perspective that can hopefully support future research in this area. Concretely, it presents the results of a systematic review of 55 studies investigating the existence of echo chambers on social media, identifying patterns across their foci, methods and findings, and shedding light on the contradictory nature of the literature. We found that the results of research on this issue seem largely influenced by methodological and data collection choices. Indeed, articles that found clear evidence of echo chambers on social media were all based on digital trace data, while those that found no evidence were all based on self-reported data. Future studies should take into account the potential biases of the different approaches and the significant potential of combining self-reported data with digital trace data.

Internettet præsenteres ofte som et farligt redskab i hænderne på terrorister. Det er dog ikke nødvendigvis sandheden. Artiklen trækker på indsigter fra studier af sunniekstremistiske grupper, Anders B. Breivik og Anonymous og diskuterer terroristers anvendelse af internettet i organiseringen og udførelsen af terrorisme. Jeg vil argumentere for, at det anarkiske og anonyme internet fører mistillid og fragmentering med sig, hvilket gør det sværere for grupper at opretholde en fælles strategi og det fælles fjendebillede. Artiklen styrker derfor fortællingen om, at det hovedsageligt er ekskluderede og socialt marginaliserede enspændere, der ender med at planlægge voldshandlinger i isolation bag computerskærmen. I forlængelse heraf vil jeg pege på, at hovedparten af potentielle terrorister drages af fysisk interaktion,
våben og eksplosioner – og ikke udviklingen af komplekse cybervåben.

Online content regulation in Turkey is characterised by extensive removal of material that has resulted in a large number of Turkish and international websites being blocked in recent years. Further, the Turkish government recently introduced a Social Media Bill, implementing a wide range of new regulations and steep penalties for social media companies, which critics say poses further threats to online freedom of expression in the country.

The European Union (EU) is an influential voice in the global debate on regulation of online speech. For that reason, two upcoming regulatory regimes might – in addition to shaping EU digital policy – create global precedents for how to regulate both online speech generally and terrorist content specifically.

Kenya has “increasingly sought to remove online content”, both through requests and increased regulation, that it deems “immoral” or “defamatory”. Following terrorist attacks on civilian targets in recent years, the country has heightened its efforts around counterterrorism as well as online content regulation. Many of Kenya’s legislations have been criticised by civil society for their “broadness”, “vagueness”, and potential “detrimental implications for freedom of expression”. A proposed social media bill, if enacted, could largely impact social media companies and their users in Kenya, such as through strict regulations on user content.
