The Need of Web Application Firewall (WAF)

Kanishk 0

Cyber-criminals are targeting web applications from all around the world in their most upstream form, costing businesses and organizations a hell lot of money and a significant risk to their brand reputation.

Recent cyber attacks on critical IT infrastructure demonstrates the urgent need for improved cybersecurity practices and measures. As the cyber threats grow, so must our abilities to neutralize them.

A Web Application Firewall (WAF) is designed to protect company’s Web applications against various critical cyber attacks such as SQL-Injection, Cross-Site Scripting (XSS), session hijacking and other OWASP top 10 vulnerability threats. It sits on an organization’s network, between a Web client and Web server and protects the organization from vulnerabilities.

 

Web application firewalls are available in three categories:

 

1. Network-based WAF:

It is deployed as a traditional security appliance which reduces the poor network performance due to network latency and several negative performance impacts. The drawback of network-based WAF is that it is very expensive to purchase and to deploy.

 

2. Application-based WAF:

It is generally placed near to the application hosting platform or it can be integrated into the application code itself. Application-based firewall benefits the network performance and more customization options. The cost of deploying Application-based firewall is quite low as compared to the Network-based WAF, but the scalability of it is not so good when it comes to deploying it into the large-sized enterprises.

 

3. Cloud-hosted WAF:

It is easy to deploy and easy-to-manage type of firewall which offers web application protection to organizations of all sizes (SMBs, enterprises, midmarket) for a very less amount of money. For deploying Cloud-hosted WAF, it only requires a simple DNS change to redirect the application traffic.

The foremost functionality of WAF is to monitor HTTP traffic to and from a web application. A WAF protects the web application by controlling its input and output which helps it to inspect every HTTPS, HTML, SOAP and XML-RPC data packets.

Application-based or a Cloud-hosted WAF is able to protect the web applications against web application attacks such as SQL injection, XSS, buffer overflows, etc., which Network firewall and Intrusion Detection Systems (IDS) are not often capable of doing.
Organizations of all sizes as well as online bankers, personal bloggers, mobile application providers, etc. can benefit the up-time by implementing WAF on their networks, and controlling & updating it in order to increase the security posture of their web based applications.

The cyber-attacks are growing with the introductions of emerging and more advanced security threats. That resulted in WAF integrating with other solutions as advanced endpoint security and distributed denial of service (DDoS) protection.
