The Comparison of Web History Forensic Tools with ISO and NIST Standards. 2022 37th International Technical Conference on Circuits/Systems, Computers and Communications (ITC-CSCC). :1–4.
Nowadays, the number of new websites in Thailand has been increasing every year. However, there is a lack of security on some of those websites which causes negative effects and damage. This has also resulted in numerous violations. As a result, these violations cause delays in the situation analysis. Additionally, the cost of effective and well-established digital forensics tools is still expensive. Therefore, this paper has presented the idea of using freeware digital forensics tools to test their performances and compare them with the standards of the digital forensics process. The results of the paper suggest that the tested tools have significant differences in functions and process. WEFA Web Forensics tool is the most effective tool as it supports 3 standards up to 8 out of 10 processes, followed by Browser History View which supports 7 processes, Browser History Spy and Browser Forensic Web Tool respectively, supports 5 processes. The Internet history Browser supports 4 processes as compared to the basic process of the standardization related to forensics.

SSL Test Suite: SSL Certificate Test Public Key Infrastructure. 2022 30th Signal Processing and Communications Applications Conference (SIU). :1–4.
Today, many internet-based applications, especially e-commerce and banking applications, require the transfer of personal data and sensitive data such as credit card information, and in this process, all operations are carried out over the Internet. Users frequently perform these transactions, which require high security, on web sites they access via web browsers. This makes the browser one of the most basic software on the Internet. The security of the communication between the user and the website is provided with SSL certificates, which is used for server authentication. Certificates issued by Certificate Authorities (CA) that have passed international audits must meet certain conditions. The criteria for the issuance of certificates are defined in the Baseline Requirements (BR) document published by the Certificate Authority/Browser (CA/B) Forum, which is accepted as the authority in the WEB Public Key Infrastructure (WEB PKI) ecosystem. Issuing the certificates in accordance with the defined criteria is not sufficient on its own to establish a secure SSL connection. In order to ensure a secure connection and confirm the identity of the website, the certificate validation task falls to the web browsers with which users interact the most. In this study, a comprehensive SSL certificate public key infrastructure (SSL Test Suite) was established to test the behavior of web browsers against certificates that do not comply with BR requirements. With the designed test suite, it is aimed to analyze the certificate validation behaviors of web browsers effectively.

A Formal Security Analysis of the W3C Web Payment APIs: Attacks and Verification. 2022 IEEE Symposium on Security and Privacy (SP). :215–234.
Payment is an essential part of e-commerce. Merchants usually rely on third-parties, so-called payment processors, who take care of transferring the payment from the customer to the merchant. How a payment processor interacts with the customer and the merchant varies a lot. Each payment processor typically invents its own protocol that has to be integrated into the merchant’s application and provides the user with a new, potentially unknown and confusing user experience.Pushed by major companies, including Apple, Google, Master-card, and Visa, the W3C is currently developing a new set of standards to unify the online checkout process and “streamline the user’s payment experience”. The main idea is to integrate payment as a native functionality into web browsers, referred to as the Web Payment APIs. While this new checkout process will indeed be simple and convenient from an end-user perspective, the technical realization requires rather significant changes to browsers.Many major browsers, such as Chrome, Firefox, Edge, Safari, and Opera, already implement these new standards, and many payment processors, such as Google Pay, Apple Pay, or Stripe, support the use of Web Payment APIs for payments. The ecosystem is constantly growing, meaning that the Web Payment APIs will likely be used by millions of people worldwide.So far, there has been no in-depth security analysis of these new standards. In this paper, we present the first such analysis of the Web Payment APIs standards, a rigorous formal analysis. It is based on the Web Infrastructure Model (WIM), the most comprehensive model of the web infrastructure to date, which, among others, we extend to integrate the new payment functionality into the generic browser model.Our analysis reveals two new critical vulnerabilities that allow a malicious merchant to over-charge an unsuspecting customer. We have verified our attacks using the Chrome implementation and reported these problems to the W3C as well as the Chrome developers, who have acknowledged these problems. Moreover, we propose fixes to the standard, which by now have been adopted by the W3C and Chrome, and prove that the fixed Web Payment APIs indeed satisfy strong security properties.
