Network-based WAFĪ low-latency hardware solution installed locally on the network. Web Application Firewall Deployment OptionsĪ WAF can be implemented one of three different ways: 1. An NGFW also incorporates more advanced features including application awareness, an intrusion prevention system (IPS) and cloud-enabled threat intelligence services. However, it can also block modern threats such as advanced malware and application-layer attacks.
Like a traditional firewall, an NGFW can detect and block attacks at the application, port and protocol levels. While a WAF is an important part of an organization’s cybersecurity strategy, it is by no means a comprehensive solution and must be supplemented by other security measures.Ī next-generation firewall (NGFW) is an advanced firewall option that combines antivirus, network firewall, WAF and other security devices into one solution. What’s the difference between a Next-Gen Firewall and a WAF?Ī WAF provides protection only from web application attacks. Put simply, a WAF protects the organization at the application level by analyzing all HTTP/HTTPS communication, whereas the network firewall acts as a barrier that prevents unauthorized access to the network on a whole. What’s the difference between a Network Firewall and a WAF?Ī WAF differs from a network firewall in terms of the type of protection it provides and how that security is applied. Hybrid Web Application Firewall: A hybrid WAF applies elements from both the blocklist and allowlist models.
Allowlist Web Application Firewall: An allowlist WAF, or positive security model, admits only traffic that is on a pre-approved list.Blocklist Web Application Firewall: A blocklist WAF, or negative security model, protects against known attacks by denying access to traffic.
There are three main types of web application firewalls: Taken together, the policies work to detect and isolate malicious traffic before it reaches a user or application. Each WAF policy or rule is designed to address an application-level threat or known vulnerability. Download the Data Sheet How Does a Web Application Firewall Work?Ī WAF operates according to a set of rules or policies defined by the network administrator. CrowdStrike Falcon® Firewall Management™ eliminates the complexity associated with native firewalls by making it easy to manage and enforce policies using a simple, centralized approach.
