0 likes•349 views
The document summarizes security issues with a single sign-on mechanism for distributed computer networks. It describes two impersonation attacks - the first allows a malicious service provider to recover a user's credential after communicating with them twice and impersonate the user. The second allows an outsider without credentials to access network services by impersonating any user. The document also notes these attacks apply to another similar single sign-on scheme. It proposes using an encryption technique to help repair the vulnerabilities.

Security Testing
Security Testing is a process to determine how well a system protects against unauthorized internal or external access or wilful damage. It is performed to check whether there is any information leakage in the sense by encrypting the application or using wide range of software etc..

- Security is a concept similar to being cautious
or alert against any danger. Network security is the condition of
being protected against any danger or loss. Thus safety plays a
important role in bank transactions where disclosure of any data
results in big loss. We can define networking as the combination
of two or more computers for the purpose of resource sharing.
Resources here include files, database, emails etc. It is the
protection of these resources from unauthorized users that
brought the development of network security. It is a measure
incorporated to protect data during their transmission and also
to ensure the transmitted is protected and authentic.
Security of online bank transactions here has been
improved by increasing the number of bits while establishing the
SSL connection as well as in RSA asymmetric key encryption
along with SHA1 used for digital signature to authenticate the
userSar writingv2
The change password page on a web application did not lock accounts after multiple failed login attempts, allowing an attacker to keep guessing passwords through brute force. To prevent brute force password cracking, the application should be configured to lock accounts for 30 minutes after 10 consecutive invalid login attempts, in accordance with the National IT Security Password Policy. This would prevent ongoing password guessing attacks and the compromise of user accounts.

This document proposes two schemes, AnonyControl and AnonyControl-F, to address privacy issues in existing access control schemes for cloud storage. AnonyControl decentralizes the central authority to limit identity leakage and achieve semi-anonymity. It also generalizes file access control to privilege control. AnonyControl-F fully prevents identity leakage and achieves full anonymity. The schemes use attribute-based encryption and a multi-authority system to securely control user access privileges without revealing identity information. Security analysis shows the schemes are secure under certain cryptographic assumptions.Recommended

A computational-dynamic-trust-model-for-user-authorization-docx
This document proposes a computational dynamic trust model for user authorization. It distinguishes between trusting beliefs in integrity and competence in different contexts. The proposed model accounts for subjectivity in trust evaluations. Simulation studies show the model achieves higher performance than other models in predicting unstable user behavior. Unlike existing approaches, the proposed model considers how context affects trust value. It distinguishes integrity trust from competence trust to make more informed authorization decisions.

The document summarizes a paper that analyzes the security of a single sign-on (SSO) mechanism for distributed computer networks proposed by Chang and Lee. It finds two impersonation attacks against their scheme - a credential recovering attack that allows a malicious provider to impersonate a user after communicating with them twice, and an impersonation attack without credentials that allows outsiders to access services without a valid credential. It proposes using verifiable encryption of RSA signatures to repair the Chang-Lee scheme and identifies sound authentication as an open problem.Android security analysis of a single sign-on mechanism for distributed comp...
This document summarizes a security analysis of a single sign-on mechanism for distributed computer networks. It identifies two impersonation attacks against an existing single sign-on scheme proposed by Chang and Lee. The first attack allows a malicious service provider to impersonate a legal user after communicating with them twice. The second allows an outsider without credentials to impersonate users and access network services. It also explains flaws in the original security arguments. An improvement is proposed using efficient verifiable encryption of RSA signatures.

This document discusses detecting spoofing and jamming attacks in wireless smart grid networks using RSS (Received Signal Strength) algorithms. It proposes a traffic analysis method using RSS to infer contextual information from jamming and spoofing attacks. The method relies only on packet transmission times and eavesdropper locations. It is intended as a baseline for evaluating protection mechanisms with different assumptions. RSS values are correlated with physical location and widely used in localization algorithms. The proposed system aims to reduce communication overhead and delay compared to existing approaches by limiting injected dummy traffic through constructing minimum connected dominating sets and shortest path trees.

This document provides a review of security mechanisms for wireless networks. It discusses attacks on wireless networks including active attacks like masquerading and modification of messages, and passive attacks like traffic analysis and eavesdropping. It then summarizes key security goals for wireless networks such as confidentiality, integrity, availability, authenticity and accountability. The document proceeds to describe security mechanisms in IEEE 802.11 standards including WEP, WPA, and WPA2. It provides details on how WPA and WPA2 improve on WEP by using stronger encryption algorithms like TKIP and AES along with message integrity checks and dynamic key generation.

Authentication and Authorization for User Roles and Device for Attack Detecti...
This document summarizes a research paper that proposes methods for user authentication and authorization to protect relational databases from insider and outsider attacks. It discusses using digital signatures, user roles, and access policies to control what resources different users can access. The proposed methods aim to detect anomalies in database access, such as SQL injection attacks, based on profiling typical application queries and constraints. A user-to-user relationship graph is also used to help with online access control. The document outlines related work on smart grid security and presents the proposed framework and modules before discussing expected experimental results.

This document proposes an image-based authentication system for email to increase security. It aims to prevent shoulder surfing, TEMPEST, and brute force attacks. The system uses a three-level security approach involving a text password, image-based authentication where the user selects an image, and a one-time numeric password sent to the user's mobile phone. Communication between the client and server uses AJAX for increased interaction and speed. The system is analyzed against existing password and authentication methods and is concluded to be highly secure and user-friendly while preventing certain attacks. Future work plans to implement more secure encryption algorithms like MD5.

- 1. SECURITY ANALYSIS OF A SINGLE SIGN-ON MECHANISM FOR DISTRIBUTED COMPUTER NETWORKS ABSTRACT: In this paper, however, we demonstrative that their scheme is actually insecure as it fails to meet credential privacy and soundness of authentication. Specifically, we present two impersonation attacks. The first attack allows a malicious service provider, who has successfully communicated with a legal user twice, to recover the user’s credential and then to impersonate the user to access resources and services offered by other service providers. In another attack, an outsider without any credential may be able to enjoy network services freely by impersonating any legal user or a nonexistent user. We identify the flaws in their security arguments to explain why attacks are possible against their SSO scheme. Our attacks also apply to another SSO scheme proposed by Hsu and Chuang, which inspired the design of the Chang–Lee scheme. Moreover, by employing an efficient verifiable encryption of RSA signatures proposed by Ateniese, we propose an improvement for repairing the Chang–Lee scheme.
