Waf Security Architecture

What is WAF? A WAF is a WAF Security Architecture. The way a WAF works is by preventing hackers from accessing websites. A WAF consists of several components such as a firewall, anti-virus protection, fraud prevention, and content filtering. In order to be included in a WAF, the website must meet certain criteria.

Cloud Waf Services: As discussed earlier, a cloud waf services provider will have a higher risk of being hacked than an on-premise firewall company. Due to this reason, companies will choose to go with an on-demand WAN application firewall market instead of a cloud-based option. On-demand application firewalls prevent attackers from entering your network by constantly monitoring all incoming traffic and blocking suspicious or erroneous packets. Most WAN firewalls will perform similar functions; however, cloud waf services will provide additional security benefits that make them more attractive for smaller enterprises.

Easy configuration: Unlike traditional on-premises application firewalls, cloud-based services are easier to configure because there is no need to install any software for the firewall to function. Furthermore, all that is needed to start a WAN application firewall is an internet connection and a gateway. No extra hardware or software is needed. This makes it ideal for small businesses that do not have the budget to purchase and manage firewall hardware or software.

Reverse Proxy: A reverse proxy is another aspect of a layered security architecture that makes it appealing to small businesses. A reverse proxy serves as the second layer of protection for your website. Rather than allowing in web traffic only through the intended destination, a reverse proxy acts as a protective firewall to keep hackers from accessing sensitive data. In a sense, a reverse proxy acts as a "gatekeeper" for all outgoing traffic.

Load Balancing Tier One: Although a traditional load balancer is also commonly used as part of the application architecture, it is a weaker link in the WAN architecture. The reason for this is that it does not have the capabilities to handle large volumes of traffic and is unable to route all that traffic to its desired destination. In essence, a load balancing tier one acts as a weaker link in the WAN architecture and is unable to handle large volumes of traffic coming to a site.

LSR/ SRP Web Application Firewalls: Although they are sometimes used together with LSR/ SRP appliances, LSR/SRP WANs perform significantly better compared to other available web application firewalls. Their biggest advantage is that they can directly interfere with other types of traffic, especially when used in conjunction with other top web application security flaws. They also have the ability to easily detect and block suspicious network connections, which significantly reduces the threat exposure to attackers. As such, LSR/SRP WANs form a crucial component of most modern enterprise-grade WAN scalability strategies.

Top Web Application Firewalls Benefits: Despite being vulnerable to all attack types, LSR/SRP web application firewalls have several significant advantages over other available types of WAN firewalls. First, they are more cost-effective. As opposed to LSR/SRP appliances, they are much less expensive to purchase and install. Since they can directly interfere with other types of traffic, they have to operate within reasonable limits of service providers' capacity. As a result, the LSR/SRP firewalls can more efficiently manage traffic than other available technologies. They also provide a number of web application security enhancements that improve customer protection against malicious attacks.

On the other hand, SRP appliances are much easier to setup and maintain. While this is an advantage in terms of cost-effectiveness, it may be an inhibiting factor in terms of application scalability. Since SRP WANs can easily adjust to higher traffic patterns, their scalability to various future traffic spikes is much better than the LSRs. In addition to this, SRP WANs can quickly adapt to changes in the underlying traffic pattern, making them highly flexible to changing business requirements.
