Amazon Route 53 Resolver DNS Firewall is a security service offered by Amazon Web Services (AWS) that helps protect your Amazon Virtual Private Cloud (Amazon VPC) resources from DNS-based attacks. DNS-based attacks are a common type of cyber attack in which an attacker uses the Domain Name System (DNS) to redirect traffic intended for one destination to a different, malicious destination.
Route 53 Resolver DNS Firewall provides a number of features that can help protect your Amazon VPC resources from these types of attacks. It allows you to set rules that allow or block DNS queries based on certain criteria, such as the source IP address of the request, the destination domain, or the type of query. You can use these rules to block malicious or unwanted queries and ensure that only legitimate traffic reaches your resources.
Route 53 Resolver DNS Firewall also includes a library of pre-built rules that you can use to protect against common DNS-based attacks, such as DNS amplification attacks and DNS cache poisoning attacks. Users can also create your own custom rules to protect against specific threats or to enforce your own security policies.
Route 53 Resolver DNS Firewall is designed to be easy to set up and manage, and it integrates seamlessly with Amazon Route 53, the AWS Domain Name System (DNS) service. It is an important tool for helping to secure your Amazon VPC resources and protect them from DNS-based attacks.
