    A client-side anti-pharming (CSAP) approach
    (Institute of Electrical and Electronics Engineers Inc., 2016) Arya, B.; Chandrasekaran, K.
    Pharming is a type of social engineering attack wherein an attacker wants to steal sensitive information of internet users. Pharming is advanced technique than Phishing attack. In phishing, attacker's URL is different from targeted legitimate website URL but in case of pharming, attacker's URL is same to legitimate URL. Pharming attacks can be conducted by exploiting vulnerabilities in DNS server, which is more advanced type of attack than phishing. It's a special attack because the attacker doesn't have to target individual user. When attacker performs pharming on a Domain Name System (DNS) server, all users who are using DNS service through that server will fall victim of pharming attack. Various techniques are proposed for avoiding pharming attack. We present an approach which uses multiple DNS servers. © 2016 IEEE.

    Health Assessment of 1485 Top Level Domain's Name Servers
    (Institute of Electrical and Electronics Engineers Inc., 2023) Adiwal, S.; Rajendran, B.; Shetty D, D.; Sudarsan, S.D.
    Domain Name System (DNS) has evolved as a critical component in the accessibility of Internet services and has therefore become a key attack vector in major Internet attacks. It is essential to monitor various DNS communications parameters, take corrective actions when needed, and prevent abuse. We propose a new set of metrics that could be monitored to assess the health of a given Top Level Domains (TLDs) nameserver. We then conduct passive probes and determine the values of the proposed parameters for the nameservers serving the 1485 TLDs of the Internet. The values of the identified metrics help to detect sluggishness in performance and form the basis for arriving at a score of their health. The presented approach is scalable across the DNS hierarchy and can be repeated periodically to detect and prevent DNS abuses. © 2023 IEEE.
