The domain name system (DNS) is a critical protocol in today’s Internet operation. It establishes a standard naming convention for human-readable, understandable, and memorable domain names and IP addresses of Internet services. The abundance of study on DNS in general and security and privacy suggests that all issues in this area have been resolved. The reality, however, is that despite the substantial amount of literature on different elements of DNS, there are still many unresolved issues. The researchers offered a standards-based security assessment using Cyber Security Evaluation Tool (CSET) to help the staffing agency understand and assess the many hazards associated with using the domain name system. Furthermore, the researchers investigate a range of potential countermeasures to such threats.
