In the OpenID Connect digital identity ecosystem, In the OpenID Connect digital identity ecosystem, for privacy reasons, this entity is distinct from Identity Providers that manage only the basic identity profile information. A relevant scenario is as follows: the User first logs in to an online service using his/her identity managed by an Identity Provider. Then, the online service asks the Attribute Authority for the additional User’s attributes (e.g., entitlements) before granting access to its resources. In some high-sensitive cases, an Attribute Authority needs proof of the User’s authentication before releasing the User’s attributes to the online service. The challenge of this scenario involving usability, security, and privacy requirements lies in finding the right mechanism to share (the minimum and necessary set of) claims of the User who is currently authenticated with the online service across multiple domains without requiring his or her re-authentication. In this paper, we present the design of two solutions based on OpenID Connect to share User claims across domains. We provide security and privacy analysis for the two solutions and a brief comparison between them.","PeriodicalId":107145,"journal":{"name":"Proceedings of the 18th International Conference on Availability, Reliability and Security","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115648176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to address the shortage of cybersecurity experts, a multi-criteria selection method is developed to increase the availability, accessibility, and quality of cybersecurity courses and certifications. This Course Selection methodology ensures high-quality training materials that meet the current and future needs of the cybersecurity industry and benefit a wide range of participants. The methodology considers six criteria and provides a scoring system to rank the occupational profiles and select the most relevant profiles for the course design.

Since static analysis of obfuscated apps often produces incomplete or misleading results, the problems of identifying and quantifying the use of specific obfuscation techniques in apps has received significant attention. Even though several existing works have addressed these problems, most studies focus on data obfuscation methods such as identifier renaming and string obfuscation, while more advanced code obfuscation methods, such as reflection and control-flow obfuscation, have received less attention. Moreover, existing approaches to detecting Android code obfuscation have significant limitations, as shown by a detailed survey that we present as part of this paper. This is in part due to a fundamental “bootstrapping” problem: since, on one hand, the landscape of Android code obfuscation is poorly known, researchers have very little guidance when designing new detection methods. On the other hand, the lack of detection methods mean that the obfuscation landscape is bound to remain largely unexplored. In this work, we aim to take the first steps towards addressing this “bootstrapping” problem. To this end, we propose two novel approaches to obfuscation detection and perform a study on over 200,000 malicious apps, in addition to 13,436 apps from Google Play. In particular, we propose a new anomaly-detection-based method for identifying likely control-flow obfuscation, and use it to perform what is, to the best of our knowledge, the first empirical study of control-flow obfuscation in Android apps. In addition to presenting new insights into the use of control-flow obfuscation, we also propose a new approach to characterizing the use of reflection-based obfuscation, which allows us to corroborate earlier findings indicating that this type of obfuscation is much more common in malware than in benign apps.","PeriodicalId":107145,"journal":{"name":"Proceedings of the 18th International Conference on Availability, Reliability and Security","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114850719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work we provide an overview of a KMS in the context of Quantum Key Distribution Networks (QKDN) and give a thorough summary of the functionality of a KMS in such an application. Beyond classical QKDNs, we discuss Post Quantum Cryptography (PQC) hybridization techniques at the KMS level. These methods add an additional layer of security against quantum computer driven attacks. We also discuss selected topics regarding the development, deployment and operation of components for such security infrastructure. In addition, relevant standards in the realm of Quantum Key Distribution (QKD) are outlined and analyzed. As some of the necessary interfaces have not been standardized, namely the interface between two KMS instances and the interface between the KMS and the Software Defined Network (SDN) Agent, we propose APIs for these two cases. The design of the interface between the KMS and QKD modules is discussed and, considering their resource constraints, a push mode for the ETSI GS QKD 004 standard is proposed. Finally, implementation details of a prototype KMS are outlined and trade-offs are discussed.","PeriodicalId":107145,"journal":{"name":"Proceedings of the 18th International Conference on Availability, Reliability and Security","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128430880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite being a recent technology, ADS-B communication does not include security measures. This exposes the communication to potential threats, including message spoofing or fake aircraft generation. To cope with such a security lack, the security community is actively proposing innovative solutions to protect ADS-B communication. However, testing and evaluating security frameworks is complex due to the limited number of simulators and the impossibility of conducting real-world experiments. In this paper, we present an OpenScope-sec an ADS-B simulator to support the security research and the implementation of novel anomaly detection systems. Our simulator extends the existing ADS-B simulator tools with the possibility of implementing a wider range of attacks. The list of attacks included is based on a preliminary analysis of the current literature, where we collected the most common attacks proposed on ADS-B communication and the existing simulators. Finally, for each attack implemented, we discuss possible anomaly detection approaches to detect the attacks and the consequent changes in legitimate parameters. order to detect possible attacks in real ADS-B messages.","PeriodicalId":107145,"journal":{"name":"Proceedings of the 18th International Conference on Availability, Reliability and Security","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126602507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
