    ENSURING SAFETY WHILE ENHANCING PERFORMANCE: ENCOURAGING REINFORCEMENT LEARNING BY ADDRESSING CONSTRAINTS AND UNCERTAINTY
    (НИЯУ МИФИ, 2024) Aghbolagh, M. A.
    Striking a balance between safety and performance remains a critical concern, despite advancements in the field. To address this issue, a versatile framework named Safety Goes Along with Performance (SGAWP) is proposed, centered on off-policy algorithms grounded in value function optimization. SGAWP utilizes reinforcement learning to navigate the data space, emphasizing high task performance while addressing risks (such as undesirable states) by incorporating safety costs into the value function. By integrating uncertainty management and task performance constraints, SGAWP aims to achieve improved safety performance alongside respectable task performance. Moreover, SGAWP leverages curiosity-driven exploration to expand the data space and employs task policies to enhance safety policy performance. As a result, SGAWP enhances safety performance with minimal loss in task performance. Beyond its success in reinforcement learning, SGAWP holds promise for applications like autonomous driving, where safety is paramount. Through rigorous experimentation across various offpolicy algorithms, SGAWP demonstrates robust generalization and achieves its objectives effectively

    Iran’s Cyber Capabilities and Assessing Security Standards for Popular Iranian Websites
    (MEPhI, 2023) Aghbolagh, M. A.; Trufanov, A. I.
    The security of online users depends on various factors. One of the most important factors are to follow security standards and use of reliable and updated technology as well as the standards and technologies that have been created in recent years specifically to increase data and communication security on websites and various internet services. However numerous studies show that the current state of global web security is not desirable yet, and these standards and technologies are not being applied as fast as they are developed. Our research in CERTFA Lab on popular Iranian websites (414 websites) show that the security of Iranian websites is not different from the global level, and very few websites are fully utilizing the security standards and modern technologies. According to our investigation, only 7 websites from our assessed sites have been used CSP2 configuration, which the implementation of Cafebazaar.ir and Virgool.io have more detail and other 5 websites just use the upgrade-insecure-requests option as a default setting for CSP. In other cases, popular websites, not only did not use the CSP header, they have also forgotten to use the basic security header. Also, the results of modern standards analysis in this study (such as DNSSEC, CAA, DMARC, SPF, and Expect-CT), which is mandatory for most Internet businesses, indicate that just Eligasht.com, one of the Iranian popular websites, has properly used these standard configurations. Since these security standards and modern technologies are easy to use and cheap to implement, we could say that the reason for this undesirable situation might be the negligence of admins and service providers.
