This first issue, “Decoding the Adversary,” focuses on whether or not you and your board of directors are doing enough to protect against cyber threats. Security is not simply a CIO, CSO, or IT department issue. Breaches, leaked documents, and cybersecurity attacks impact stock prices and competitive edge. It is a responsibility that must be shared amongst all employees, and CEOs and board members must proactively mitigate future challenges. -

Transcript of Episode #168 Page 1 of 18 Transcript of Episode #168 ClickJacking Description: Steve and Leo discuss yet another challenge to surfing safely in the web world: Known as "ClickJacking," or more formally as "UI Redressing," this class of newly popular threats tricks web users into performing web-based actions they don't intend by leading them to believe they are doing something else entirely.

It's time for Security Now!, the show where we cover everything you'd ever want to know about security. And we do it with a guy who is the king, really, as far as I'm concerned, the man who discovered spyware, named spyware, wrote some of the most used security utilities out there, including ShieldsUP!, Mr. Steve Gibson of GRC.com. Hi, Steve. Steve Gibson: Yes, in fact sometimes we're discussing things that you'd rather wish weren't the case. I mean... Leo: Well, lately it's been kind of bleak because it's like, there's bad stuff, and there doesn't really seem like there's any cure. Steve: Yes, that's true. -

0.1. PROBLEMS 1 0.1 Problems 1. Among the fundamental challenges in information security are confi- dentiality, integrity, and availability, or CIA. a. Define each of these terms: confidentiality, integrity, availability. b. Give a concrete example where confidentiality is more important than integrity. c. Give a concrete example where integrity is more important than confidentiality. d. Give a concrete example where availability is the overriding con- cern. 2. From a bank's perspective, which is usually more important, the in- tegrity of its customer's data or the confidentiality of the data? From the perspective of the bank's customers, which is more important? 3. Instead of an online bank, suppose that Alice provides an online chess playing service known as Alice's Online Chess (AOC). Players, who pay a monthly fee, log into AOC where they are matched with another player of comparable ability. a. Where (and why) is confidentiality important for AOC and its customers? b. Why is integrity necessary? c. Why is availability an important concern? 4. Instead of an online bank, suppose that Alice provides an online chess playing service known as Alice's Online Chess (AOC).

Where would security protocols be used? d. Is software security a concern for AOC? Why or why not? 5. Some authors distinguish between secrecy, privacy, and confidential- ity. In this usage, secrecy is equivalent to our use of the term con- fidentiality, whereas privacy is secrecy applied to personal data, and 2 confidentiality (in this misguided sense) refers to an obligation not to divulge certain information. -

A Semi-Automated Security Advisory System to Resist Cyber-Attack in Social Networks
A Semi-Automated Security Advisory System to Resist Cyber-attack in Social Networks Samar Muslah Albladi and George R S Weir University of Strathclyde, Glasgow G1 1XH, UK {samar.albladi; george.weir}@strath.ac.uk Abstract. Social networking sites often witness various types of social engi- neering (SE) attacks. Yet, limited research has addressed the most severe types of social engineering in social networks (SNs). The present study in- vestigates the extent to which people respond differently to different types of attack in a social network context and how we can segment users based on their vulnerability. In turn, this leads to the prospect of a personalised security advisory system. 316 participants have completed an online-ques- tionnaire that includes a scenario-based experiment. The study result re- veals that people respond to cyber-attacks differently based on their de- mographics. Furthermore, people’s competence, social network experience, and their limited connections with strangers in social networks can decrease their likelihood of falling victim to some types of attacks more than others. Keywords: Advisory System, Social Engineering, Social Networks. 1 Introduction Individuals and organisations are becoming increasingly dependent on working with computers, accessing the World Wide Web and, more importantly, sharing data through virtual communication. This makes cyber-security one of today’s greatest issues. Pro- tecting people and organisations from being targeted by cybercriminals is becoming a priority for industry and academia [1]. This is due to the huge potential damage that could be associated with losing valuable data and documents in such attacks. Previous research focuses on identifying factors that influence people’s vulnerability to cyber-attack [2] as the human has been characterised as the weakest link in infor- mation security research. -
Is the Mafia Taking Over Cybercrime?*
Is the Mafia Taking Over Cybercrime?* Jonathan Lusthaus Director of the Human Cybercriminal Project Department of Sociology University of Oxford * This paper is adapted from Jonathan Lusthaus, Industry of Anonymity: Inside the Business of Cybercrime (Cambridge, Mass. & London: Harvard University Press, 2018). 1. Introduction Claims abound that the Mafia is not only getting involved in cybercrime, but taking a leading role in the enterprise. One can find such arguments regularly in media articles and on blogs, with a number of broad quotes on this subject, including that: the “Mafia, which has been using the internet as a communication vehicle for some time, is using it increasingly as a resource for carrying out mass identity theft and financial fraud”.1 Others prescribe a central role to the Russian mafia in particular: “The Russian Mafia are the most prolific cybercriminals in the world”.2 Discussions and interviews with members of the information security industry suggest such views are commonly held. But strong empirical evidence is rarely provided on these points. Unfortunately, the issue is not dealt with in a much better fashion by the academic literature with a distinct lack of data.3 In some sense, the view that mafias and organised crime groups (OCGs) play an important role in cybercrime has become a relatively mainstream position. But what evidence actually exists to support such claims? Drawing on a broader 7-year study into the organisation of cybercrime, this paper evaluates whether the Mafia is in fact taking over cybercrime, or whether the structure of the cybercriminal underground is something new. It brings serious empirical rigor to a question where such evidence is often lacking. -

A Case Study on Clickjacking Attack and Location Leakage
International Journal of Scientific & Engineering Research, Volume 5, Issue 7, July-2014 190 ISSN 2229-5518 A Case Study on Clickjacking Attack and Location Leakage Lim Chin Nei, Loo Yow Cherng, Manmeet Mahinderjit Singh Abstract— The advanced in technologies such as mobile devices, GSP, WIFI, and 3G has encourage the information sharing using social media. The large amount of information shared on social media often lead to security issues which are unaware by the users. This information may include sensitive information such as a person’s name, location, relationship status and many more and can be dangerous if is put in a wrong hand. In this research, we provide a review on the type of social media ad what are the current threat in social media. We then focus on two specific threat namely clickjacking and location leakage, and proposed a solution for each of it as well as the evaluation of the solution.
