WAF as a Service - Managed Web Application Firewall
Protect web apps, Mobile Apps and APIs
Web Application Firewall (WAF) and why is it important
A Web Application Firewall (WAF) is a security solution that helps protect web applications from various online threats such as cross-site scripting (XSS), SQL injection, and other attacks. It works by monitoring and filtering incoming traffic to web applications, blocking malicious requests, and preventing unauthorized access.
Today a WAF is used to protect web apps, APIs, and business-to-business transactions, in such cases, we often refer to it as Web Application and API Protection (WAAP).
WAF (or WAAP) is essential for business security because attackers frequently target web applications to exploit vulnerabilities and steal sensitive data. A WAF can help detect and prevent such attacks, thereby safeguarding customers’ personal information, financial data, and other critical assets. Additionally, WAFs can help companies comply with various industry standards and regulations related to data protection, such as PCI DSS and HIPAA. Deploying a WAF can significantly enhance the business security posture and protect brand reputation.
How does managed WAF as a Service work?
Managed WAF as a Service is a cloud-based solution that provides web application firewall functionality without requiring to install or manage any hardware or software.
Clients benefit from the advanced security capabilities of a web application firewall without worrying about the complexities of managing and maintaining their own WAF infrastructure. This can save time, resources, and money while providing reliable, scalable, and effective protection for web applications and APIs.
Here is how it typically works:
1
Sign up for the WAF as a Service through a provider and configure the DNS to point to the new firewall service instead of the web app
2
It intercepts all incoming traffic to your app, using advanced filtering algorithms to analyze each request.
3
This service detects any malicious requests; it blocks them from reaching the web app, preventing any potential attacks.
4
You will have access to real-time alerts and notifications to help you stay informed about potential attacks and suspicious activity.
5
WAF as a Service can provide detailed reporting and analysis of website traffic, giving insights into potential vulnerabilities and threats that can be addressed proactively.
Why do you need a WAF or a WAAP?
Your website or app generates revenue
The managed WAF service will prevent cyber threats and downtime to ensure your website or app doesn't loose revenues.
You use server side applications
If you use PHP, Python, Ruby, C#, JavaScript, etc., you will need to secure your application and enhance its performance.
There is a risk if your site is hacked
Upgrading your website security will prevent it from being hacked and mitigate your risk.
Benefits of WAF as a Service for businesses
There are several benefits that a managed WAF as a Service can provide for businesses, including:
It can help protect web applications, APIs from various online threats such as cross-site scripting, SQL injection and other attacks, as well as protect customer data and prevent costly information leaks.
Clients don’t need to invest in any hardware or software, and can quickly deploy it without any special expertise.
It can save time and money compared to managing and maintaining own WAF infrastructure.
WAF as a Service is designed to scale automatically to meet the needs of businesses, whether dealing with seasonal traffic spikes or rapid growth. Clients can easily adjust plans to match their needs, without worrying about overprovisioning or underutilizing resources.
WAF as a Service typically operates on a subscription-based model, allowing clients to pay only for the resources you need. This can help reduce upfront costs and avoid costly capital expenditures.
WAF as a Service can help companies comply with various industry standards and regulations related to data protection, such as PCI DSS and HIPAA. This can help avoid costly fines and legal issues while demonstrating commitment to data privacy and security.
Types of Attacks Web Application Firewall Protect Against
1. Cross-Site Scripting (XSS) attacks
XSS attacks attempt to inject malicious code into web pages to steal sensitive information or perform other malicious actions. WAF can detect and block such attacks by inspecting incoming traffic and filtering out any malicious payloads.
2. SQL Injection attacks
SQL injection attacks exploit vulnerabilities in web applications that allow attackers to execute arbitrary SQL commands, potentially leading to data theft or destruction. WAF can detect and block such attacks by analyzing incoming traffic and blocking any suspicious SQL commands.
3. Cross-Site Request Forgery (CSRF) attacks
CSRF attacks attempt to trick users into performing actions on a website that they did not intend to perform. WAF can detect and block such attacks by inspecting the request headers and looking for any inconsistencies.
4. Distributed Denial of Service (DDoS) attacks
DDoS attacks attempt to overwhelm a website with traffic, making it unavailable to legitimate users. WAF can detect and block such attacks by analyzing incoming traffic and filtering out any suspicious traffic patterns.
5. File Inclusion attacks
File inclusion attacks exploit vulnerabilities in web applications that allow attackers to include files from outside the web root directory, potentially leading to unauthorized access or data theft. WAF can detect and block such attacks by inspecting incoming traffic and blocking any attempts to include files from outside the web root directory.
