Security and Privacy Concerns of Internet Single Sign-On"
Security and Privacy Concerns of Internet Single Sign-On Risks and Issues as They Pertain to Liberty Alliance Version 1.0 Specifications Authors: Gary Ellison, Jeff Hodges, Susan Landau Date: 6 Sep 2002 Introduction As noted in ‘‘A Brief Introduction to Liberty,’’ for the man on the street, the lawyer in her office, the shopper or investor at home, identity on the Internet is a burdensome and off-putting process. There is one sign-on and password for the online book merchant, another for the corporate network and for each of its pieces --- the client’s private pages, the outsourced human resources office, the online travel agency --- yet another pair for accessing Lands End, still another for Bank of America. The same holds for business-to-business interactions. The result is a cumbersome user experience. The first challenge of Web services is a simple and secure identity mechanism, the second, and equally important, concern is privacy protection. Single sign-on and federated network identity (a system for binding multiple accounts for a given user) are key to solving these issues. A federated system allows businesses to manage their own resources including customer data. Federated network identity enables customers to retain some control over which companies have access to their own information [INTRO]. The Liberty Alliance was formed to deliver and support a federated network identity solution for the Internet, enabling single sign-on for consumers as well as business users in an open, federated way. The Liberty Alliance version 1.0 specifications (referred to as the Liberty Specifications or Liberty protocols throughout this document) clear the way for a user to have a seamless Internet experience and simplify the business of conducting business with multiple Web sites. -

Ease of services for Shopping, Travel, Internet Banking, Social Media, chat and collaboration Apps etc. have become part of one’s life where these identities have name, media content, confidential notes, business projects and credit cards. Convenience and connections brings the ease of connectivity and services so does come the concerns related to unauthorized usage and fraudulent transactions that could be lead to loss of money, time, emotions and even life. Web defacement, fake accounts, account hijacking, account lock and unavailability of services has become a common online news and distress for many. There are different Web Attacks and exploits that have sprung up with time and usage for different type of illegal actions performed everyday online. Cross Site Request Forgery Attack is one of the Web top 10 exploited attacks for the past 5 years (Source OSWAP) which can maliciously exploit online services, where unauthorized actions are performed by the fraudulent user on behalf of a trusted and authenticated account for website. -
Improving the Effectiveness of Behaviour-Based Malware Detection

Information Studies (Hons) (Information Systems Management) UiTM, Malaysia Master of Information Technology (Computer Science) UKM, Malaysia A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at the School of Engineering and Information Technology University of New South Wales Australian Defence Force Academy Copyright 2012 by Mohd Fadzli Marhusin PLEASE TYPE THE UNIVERSITY OF NEW SOUTH WALES Thesis/Dissertation Sheet Surname or Family name: MARHUSIN First name: MOHD FADZLI Other name/s: Abbreviation for degree as given in the University calendar: PhD (Computer Science) School: School of Engineering and Information Technology (SEIT) Faculty: Title: Improving the Effectiveness of Behaviour-based Malware Detection Abstract 350 words maximum: (PLEASE TYPE) Malware is software code which has malicious intent but can only do harm if it is allowed to execute and propagate. Detection based on signature alone is not the answer, because new malware with new signatures cannot be detected. Thus, behaviour-based detection is needed to detect novel malware attacks. Moreover, malware detection is a challenging task when most of the latest malware employs some protection and evasion techniques. In this study, we present a malware detection system that addresses both propagation and execution. Detection is based on monitoring session traffic for propagation, and API call sequences for execution. For malware detection during propagation, we investigate the effectiveness of signature-based detection, anomaly-based detection and the combination of both. The decision-making relies upon a collection of recent signatures of session-based traffic data collected at the endpoint level. -
Monthly Report on Online Threats in The
MONTHLY REPORT ON ONLINE THREATS REPORTING PERIOD: IN THE BANKING SECTOR 19.04–19.05.2014 One of the main events during the reporting period was the leakage of payment credentials belonging to eBay users. Details of the incident and other detected threats can be found in the section ‘Key events in the online banking sphere’ below. Overall statistics During the reporting period, Kaspersky Lab solutions blocked 341,216 attempts on user computers to launch malware capable of stealing money from online banking accounts. This figure represents a 36.6% increase compared to the previous reporting period (249,812). This increase in banking malware activity is most likely related to the onset of the vacation season, when customers actively use their payment data to make all types of purchases online. 24 001 - 78 000 16 001 - 24 000 7101 - 16 000 2101 - 7100 1 - 2100 Number of users targeted by banking malware The number of users attacked using these types of programs during the reporting period is shown in the diagram below (Top 10 rating based on the number of users attacked, in descending order): 77,412 27,071 21,801 22,115 13,876 15,651 17,333 5417 6883 7347 France Vietnam Austria India Germany United USA Russian Italy Brazil Kingdom Federation © 1997-2014 Kaspersky Lab ZAO.

Security Testing Is a Popular, but Often Misunderstood Concept
As lowering temperatures signal the last days of summer, many of you are already behind your workstations tackling new threats and looking fondly back at the days at the beach. Youʼre not alone, the security landscape is evidently waking up, as both black hats and white hats are back at their keyboards. During the past few months weʼve been sorting through a significant number of article submissions. The result is another issue of (IN)SECURE we think youʼll enjoy. While wrapping up on this issue, we finalized our travel plans to attend ENISAʼs Summer School on Network and Information Security in Greece, SOURCE Conference in Barcelona and BruCON in Brussels. This means weʼll be seeing many of you during September and listening to a myriad of inspiring talks. Itʼs going to be an stimulating month!
