#F5 Web Application Firewall Interview Questions and Answers
The F5 ASM solution is made up of several different components, all of which work together to provide protection for web applications. The first component is the ASM Policy Manager, which is used to create and manage security policies. The second component is the ASM Web Application Firewall, which enforces the security policies created in the Policy Manager. The third component is the ASM Application Security Monitor, which monitors web traffic and provides visibility into attacks and vulnerabilities. Finally, the fourth component is the ASM Threat Intelligence Service, which provides real-time intelligence on the latest threats and attacks.
The F5 ASM is a web application firewall that helps to protect web applications from attacks. It does this by inspecting incoming traffic and blocking requests that are deemed to be malicious. The F5 ASM can also be used to monitor traffic and generate reports on activity, which can be helpful in identifying potential threats.
There are a few important metrics to keep in mind when using the F5 ASM. First, you want to make sure that you are monitoring traffic levels and patterns so that you can identify any potential attacks early on. Additionally, you want to keep an eye on your ASM policy to ensure that it is effective in blocking attacks and not causing false positives. Finally, you also want to monitor your system resources to ensure that the ASM is not causing any performance issues.
F5 ASM is a web application firewall that provides protection for web applications from attacks such as SQL injection, cross-site scripting, and session hijacking. It does this by inspecting all incoming traffic and blocking malicious requests. F5 ASM is unique in that it is fully integrated with the F5 BIG-IP platform, which provides additional features and benefits such as load balancing, application security, and traffic management.
You can configure a security policy using the F5 ASM by creating a new security policy and then adding the desired rules. To do this, you will first need to log into the ASM Policy Builder. Once you are in the Policy Builder, you will click on the “Create Policy” button. This will open a new window where you will need to enter the policy name, description, and choose the type of policy you want to create. After you have entered all of the required information, you will click on the “Create” button. This will add the new policy to the Policy Builder. Next, you will need to add the desired rules to the policy. To do this, you will click on the “Add Rule” button. This will open a new window where you will need to enter the rule name, description, and choose the type of rule you want to create. After you have entered all of the required information, you will click on the “Create” button. This will add the new rule to the policy.
How does a web application firewall (WAF) work?
A WAF protects your web apps by filtering, monitoring, and blocking any malicious HTTP/S traffic traveling to the web application, and prevents any unauthorized data from leaving the app. It does this by adhering to a set of policies that help determine what traffic is malicious and what traffic is safe. Just as a proxy server acts as an intermediary to protect the identity of a client, a WAF operates in similar fashion but in the reverse—called a reverse proxy—acting as an intermediary that protects the web app server from a potentially malicious client.
WAFs can come in the form of software, an appliance, or delivered as-a-service. Policies can be customized to meet the unique needs of your web application or set of web applications. Although many WAFs require you update the policies regularly to address new vulnerabilities, advances in machine learning enable some WAFs to update automatically. This automation is becoming more critical as the threat landscape continues to grow in complexity and ambiguity.

The difference between a web application firewall (WAF), an intrusion prevention system (IPS) and a next-generation firewall (NGFW)
An IPS is an intrusion prevention system, a WAF is a web application firewall, and an NGFW is a next-generation firewall. What’s the difference between them all?
An IPS is a more broadly focused security product. It is typically signature and policy based—meaning it can check for well-known vulnerabilities and attack vectors based on a signature database and established policies. The IPS establishes a standard based off the database and policies, then sends alerts when any traffic deviates from the standard. The signatures and policies grow over time as new vulnerabilities are known. In general, IPS protects traffic across a range of protocol types such as DNS, SMTP, TELNET, RDP, SSH, and FTP. IPS typically operates and protects layers 3 and 4. The network and session layers although some may offer limited protection at the application layer (layer 7).
A web application firewall (WAF) protects the application layer and is specifically designed to analyze each HTTP/S request at the application layer. It is typically user, session, and application aware, cognizant of the web apps behind it and what services they offer. Because of this, you can think of a WAF as the intermediary between the user and the app itself, analyzing all communications before they reach the app or the user. Traditional WAFs ensure only allowed actions (based on security policy) can be performed. For many organizations, WAFs are a trusted, first line of defense for applications, especially to protect against the OWASP Top 10—the foundational list of the most seen application vulnerabilities. This Top 10 currently includes:

A next-generation firewall (NGFW) monitors the traffic going out to the Internet—across web sites, email accounts, and SaaS. Simply put, it’s protecting the user (vs the web application). A NGFW will enforce user-based policies and adds context to security policies in addition to adding features such as URL filtering, anti-virus/anti-malware, and potentially its own intrusion prevention systems (IPS). While a WAF is typically a reverse proxy (used by servers), NGFWs are often forward proxys (used by clients such as a browser).
