HOW WAF PROTECTS YOUR WORKLOADS FROM CYBER MISCHIEF
More and more businesses are taking advantage of the many benefits of cloud computing to move their data and workloads to the cloud. Chief among these is security. Public clouds are always perceived as safe: after all cloud providers owes it to their clients to ensure security, and to the success of their own business, as well. AWS for one takes security very seriously to the extent to meeting regulatory compliances for several industries. But cloud security must never be taken for granted. AWS itself has always defined security in the cloud as a shared responsibility. Which means you, as customer, must ensure preventive measures are put into place to keep your workloads and data safe from cyber threats. One of the fundamental solutions that AWS offers to protect your web applications is AWS WAF, (Web Application Firewall)
As its name suggests, AWS WAF is a firewall that acts as a protective wall between your workloads and malicious cyber activities, such as SQL Injection, cross-site scripting, etc. It is highly customizable, allowing you to configure rules to permit or block entry based on conditions you set as filters, e.g. IP addresses, HTTP headers, etc.
And you don’t need to set up separate servers to manage the firewall; AWS WAF is designed for integration with supported services. Every time a request is received by a service for your web-application, it is re-directed to WAF. The firewall compares pre-set parameters to see if the request complies with the rule that has been set. If the request doesn’t meet the stipulated condition, it get blocked. If it does meet the preconfigured rules, the request is granted.
