    DEH-DoSv6:
    (Bulletin of Electrical Engineering and Informatics, 2021-02) Naagas, Marlon A.; Malicdem, Alvin R.; Palaoag, Thelma D.
    With the rapid depletion of IPv4 protocol in these recent years, the IETF introduced IPv6 as a solution to address the exhaustion, however, as a new protocol exists, new characteristics have been introduced and new threats have been discovered. Extension Headers are the new characteristics of IPv6 that have an emerging and re-emerging security threats that is needed to be taken into consideration during the full migration to the IPv6 network. This study revealed that up to this moment, the popular vendors are still vulnerable and doesn’t have any default protection to deal with extension headers’ Denial of Service Attack (DoS). Also, this study leads to the development of new security model which creates a new solution to address the emerging threats of IPv6 extension headers’ Denial of Service Attack. Moreover, the results of this study show that our proposed security model is more effective in terms of neutralizing the unwanted traffic causing evasion attack by filtering, rate-limiting and discarding the malformed packets of prohibited extension headers’ payload versus the traditional router protection.

    Network security policies and procedure based on the threat-driven approach for Ilocos Sur Polytechnic State College
    (Don Mariano Marcos Memorial State University – Mid La Union Campus, 2021-04) Tizon, Joshua M.; Patacsil, Joseph A.; Malicdem, Alvin R.; Cabading, Jose Mari N.; Ledda, Mark Kristian C.
    Avoiding the numerous consequences that may result from a cyber-attack, the colleges and universities should take affirmative steps to strengthen their networks and defend their data. This paper primarily aimed to help strengthen the privacy, security, and safety of information of Ilocos Sur Polytechnic State College by designing a Network Security Policy and Procedure for ISPSC using a threat-driven approach. The descriptive research design to analyze the data gathered from the testing of the security and accuracy of the design policy of a network was used. The findings show that the crafted policy and standard operational procedure for network security of the said institution shall be approved by the Board of Trustees of the institution with the integration of the additional policies provided by the researcher. The designed policy and standard operational procedures for the network security of the institution has been successfully evaluated by the technical experts and can be utilized to reinforce the compliance of ISO 27001 and ISO 9001:2015 Certification. The network security has proven to be very much good in the three aspects of validation as to functionality, efficiency, and benefits as felt need of institution.
