Questions and answers designated by tag: DNS Resolution

How does the DNS resolution process work when a DNS server needs to resolve a domain name but is not authoritative for the domain, and what mechanisms are involved in this scenario?

Tuesday, 02 April 2024 by EITCA Academy

When a DNS server needs to resolve a domain name that it is not authoritative for, the process involves multiple steps to ultimately obtain the IP address associated with the domain name. This scenario typically occurs when a DNS server receives a query for a domain name that is not within its authoritative zone. The

Is the DNS CNAME record the one that needs to change its values if the domain name mapping to an IP address is changed?

Tuesday, 19 December 2023 by Acácio Pereira Oliveira

The DNS CNAME (Canonical Name) record is an essential component of the Domain Name System (DNS) that allows domain names to be mapped to their corresponding IP addresses. When the IP address associated with a domain name changes, it is necessary to update the values of the CNAME records to ensure proper functioning of the

How does an attacker carry out a DNS rebinding attack without modifying the DNS settings on the user's device?

Saturday, 05 August 2023 by EITCA Academy

An attacker can carry out a DNS rebinding attack without modifying the DNS settings on the user's device by exploiting the inherent functionality of web browsers and the way they handle DNS resolution. DNS rebinding attacks leverage the time disparity between DNS resolution and browser enforcement of same-origin policies to deceive the browser into making

How do preflighted requests help prevent unauthorized requests in web applications?

Saturday, 05 August 2023 by EITCA Academy

Preflighted requests play a important role in preventing unauthorized requests in web applications by mitigating the risk of DNS rebinding attacks. DNS rebinding attacks exploit the way web browsers handle DNS resolution to bypass the same-origin policy and execute unauthorized actions on behalf of an attacker. These attacks can lead to unauthorized access to sensitive

What is the purpose of the hosts file in Windows Server?

Saturday, 05 August 2023 by EITCA Academy

The hosts file in Windows Server plays a important role in the Domain Name System (DNS) resolution process by mapping domain names to IP addresses. It serves as a local text file that contains a list of hostname-to-IP address mappings, allowing the operating system to resolve domain names to their corresponding IP addresses without the
