These days, businesses overwhelmingly develop and buy web applications. The web apps spread throughout an enterprise and are increasingly accessed by both internal and external users, related defenses are required beyond the network perimeter.

Online financial services, eCommerce websites, or any other kind of services involving interactions with business partners and customers is at a high risk of security attacks. In these cases, Web Application Firewalls can help prevent data thefts and fraud. As WAF are not built to defend from all kinds of attacks, it functions as part of an array of security tools, which backs a comprehensive web application security program.

Another important benefit of WAF is obtaining protection against zero-day attacks: newborn malware, which is not identified by any behavior analysis – the most dangerous type of security threat, that traditional firewalls aren’t equipped to prevent or mitigate.

WAF are unique in their capabilities like:

• Validate code inputs, thereby stops XSS, SQL injection , and directory traversal attacks
• Spot session, cookie, or parameter tampering attacks
• Block attacks, which exploit a weakness in custom web properties
• Inspect SSL-encrypted traffic to detect all kinds of embedded threats
• Avert threats, which execute by exploiting logic loopholes
• Enables compliance with the need for PCI DSS
• Protect against DDoS attacks

Underpinning all these protections, market-leading WAF like Indusface’s AppTrana also ensures support for a signature-based component and network-layer access control models for detecting known security threats.
