Web Application FirewallWhat is Cloud-Based Web Application Firewall (WAF)?

WAFA regular web application firewall (WAF) provides security by operating through an application or service. Blocking service calls, inputs and outputs that do not meet the policy of a firewall, i.e. set of rules to a HTTP conversation.

The rules to blocking an attack can be customized depending on the role in protecting websites that WAFs need to have. This is considered an evolving information security technology, more powerful than a standard network firewall, or a regular intrusion detection system.

WAFs become integrated with the cloud

Today, WAF products are deeply integrated with network technologies such as load balancing and — cloud.

Cloud-based WAFs, thus, utilize all advantages of WAFs and share that threat detection information among all tenants of the service, which improves results and speeds up detection rates. The whole community learns from an attack to any website sharing a single cloud-based WAF service. Plus, cloud based WAF tech is:

Elastic

Scalable

Fast

Easy to set up

Offered as pay-as-you-grow service

Sharing back reports

By using cloud-based WAFs, clients don’t need to make any software or hardware changes and tunings to their system, and can successfully protect their websites from threats by applying custom rules and deciding on the aggressiveness of the protection.

This service is used and considered ideal by anyone from financial institutions to mid-sized businesses and trading platforms, to government bodies, e-commerce vendors, and so on.

Protection against vulnerabilities:

Identity theft

Access to confidential/unauthorized data

Falsified transactions

Injection flaws (such as SQL injection)

Broken authentication session

Cross-site scripting (XSS flaws)

Sensitive data exposure

Forged requests to access functionality

Forged HTTP requests to a vulnerable web application

Vulnerable component exploit

With cloud space opening up and bringing full virtualization of OS, of storage, of software, platform, and infrastructure, more applications need to be developed for the cloud (while most are not) and remain secure on the cloud.

With WAF in the cloud, traffic is being redirected to traffic scrubbing and protecting proxy farm of WAFs. Cloud-based WAF service providers will often include a full threat analysis, exception handling policies, as well as continuous monitoring of their service

Web Threat Protection for Financial ServicesWTPFS enables financial firms to deal with the challenges of a digital world, where new technologies create opportunities for greater customer engagement but can also open the doors to higher levels of cyber-attack and create a far wider remit for diligence in security.

ConclusionA Web application firewall (WAF) is a firewall that monitors, filters or blocks the HTTP traffic to and from a Web application. WAF offers good security for any website that needs to protect its database and users
