What is Reverse Proxy? Reverse Proxy is a server that is positioned in front of webservers. As a cybersecurity professional, you would place a reverse proxy typically behind the firewall in your private network and it would direct client requests to the appropriate backend server.

A hacker alters IP addresses attached to domains in a DNS server with a fake DNS entry. A user attempts to navigate to a specific domain, and the DNS server sends them to the IP address associated with that domain. That’s how DNS poisoning or spoofing works: A hacker alters IP addresses attached to domains in a DNS server with a fake DNS entry. A user attempts to navigate to a specific domain, and the DNS server sends them to the IP address associated with that domain. The hacker...

The Domain Name System allows you to access remote systems by entering human-readable device hostnames rather than IP addresses. DNS works by creating a mapping between a domain name, such as “www.alliedtelesis.com”, and its IP address. These mappings are held on DNS servers. DNS translates meaningful domain names into IP addresses for networking equipment to locate and address these devices. The benefits of DNS are that domain names: can map to a new IP address if the...
