Understanding And Combatting Terrorist Networks: Coupling Social Media Mining With Social Network Analysis, Benn Van Den Ende
Understanding And Combatting Terrorist Networks: Coupling Social Media Mining With Social Network Analysis, Benn Van Den Ende
Australian Information Security Management Conference
Throughout the past decade the methods employed by terrorist organisations have changed drastically. One of these key changes has been associated with the rise of social media such as Facebook, Twitter, YouTube and blogging in general. Terrorist organisations appear to be using the wide reach and vast network capabilities created by social media to disseminate propaganda, radicalise susceptible individuals, recruit potential fighters and communicate strategic and operational objectives. However, this growing terrorist presence on Social Media can also offer invaluable insights into the social networks of terrorist organisations through the use of Social Media Mining and Social Network Analysis. By …

A Survey Of Social Media Users Privacy Settings & Information Disclosure, Mashael Aljohani, Alastair Nisbet, Kelly Blincoe
Australian Information Security Management Conference
This research utilises a comprehensive survey to ascertain the level of social networking site personal information disclosure by members at the time of joining the membership and their subsequent postings to the sites. Areas examined are the type of information they reveal, their level of knowledge and awareness regarding how their information is protected by SNSs and the awareness of risks that over-sharing may pose. Additionally, this research studies the effect of gender, age, education, and level of privacy concern on the amount and kind of personal information disclosure and privacy settings applied. A social experiment was then run for …

Using Graphic Methods To Challenge Cryptographic Performance, Brian Cusack, Erin Chapman
Australian Information Security Management Conference
Block and stream ciphers have formed the traditional basis for the standardisation of commercial ciphers in the DES, AES, RC4, and so on. More recently alternative graphic methods such as Elliptic Curve Cryptography (ECC) have been adopted for performance gains. In this research we reviewed a range of graphic and non-graphic methods and then designed our own cipher system based on several graphic methods, including Visual Cryptography (VC). We then tested our cipher against RC4 and the AES algorithms for performance and security. The results showed that a graphics based construct may deliver comparable or improved security and performance in …
