DNS and its security (DNSSEC) are critical topics for online businesses.
Domain Name System Security Extensions, or DNSSEC, is a group of security measures created to provide cryptographic authentication to DNS data. It checks and proves the integrity of DNS data so you can be sure they haven’t been altered.
Network experts commonly describe it as a chain of trust because it verifies every point in the process a DNS query follows.
DNS for CDN – the topic of today’s article. We will explain what the relationship between them is and what DNS and CDN mean. So, let’s get deep into this.
CDN is an abbreviation for Content Delivery Network, and it refers to a large network of servers located in various geographical locations. The fundamental goal of these servers is to cover a large area and respond quickly to potential users’ requests. The required information, such as photos, video, and code, is stored in the cache memory of each server. They also want to be as close to the users as possible. As a result, the service is better and faster. Furthermore, the CDN has the additional benefit of load balancing. As a result, the performance of the primary server is improved, and the strain on it is reduced.
A Secure Shell Fingerprint (SSHFP) record is a resource record that specifies the SSH keys connected with a host/ domain name. In addition, this provides remote connection log and networking services over an untrusted channel. When a public key is not identified, we use the Secure Shell Fingerprint record. Additionally, it will be kept locally and used for connection validation in the future.
