Fortinet FCP_FWB_AD-7.4 - FCP - FortiWeb 7.4 Administrator

HTTP rewriting is a feature in FortiWeb that allows administrators to modify HTTP requests and responses for various purposes, including security enhancements, user experience improvements, and application functionality. One common use case for HTTP rewriting is to redirect HTTP traffic to HTTPS, ensuring that all communications between clients and the server are encrypted and secure.​

Explanation of Options:

A. To redirect HTTP to HTTPS:This is a valid reason to implement HTTP rewriting. By rewriting incoming HTTP requests to HTTPS, administrators can enforce secure connections, protecting data integrity and confidentiality. FortiWeb supports this functionality, allowing seamless redirection from HTTP to HTTPS.​

B. To implement load balancing:Load balancing is not typically achieved through HTTP rewriting. Instead, it involves distributing network traffic across multiple servers to ensure availability and reliability. FortiWeb provides load balancing features, but these are separate from HTTP rewriting capabilities.​

C. To replace a vulnerable element in a requested URL:While HTTP rewriting can modify URLs, its primary purpose is not to replace vulnerable elements within URLs. Addressing vulnerabilities typically involves input validation, sanitization, and other security measures rather than rewriting URLs.​

D. The original page has moved to a new URL:This is another valid reason to implement HTTP rewriting. When a webpage's URL changes, rewriting rules can redirect requests from the old URL to the new one, ensuring users can still access the content without encountering errors.​

In summary, both options A and D are correct reasons to implement HTTP rewriting. However, in the context of FortiWeb's functionalities, redirecting HTTP to HTTPS (option A) is a common and significant use case, as it enhances security by ensuring encrypted connections.

In Active-Passive high availability (HA) mode, the active unit is responsible for handling traffic while the passive unit remains idle, ready to take over in case of a failure. When a failover occurs, the active unit sends out gratuitous ARP messages to notify neighboring devices about the change in the active unit’s IP address. This ensures that the network devices update their ARP tables and can forward traffic to the new active unit.

In FortiWeb's API protection mechanisms, there are distinctions between the traditional API gateway protection schema and the machine learning (ML) based API protection schema:​

Data Type Support: The API gateway protection schema has the capability to support various data types beyond just strings, allowing for more comprehensive validation and enforcement of API schemas. ​

Schema Adaptability: The ML-based API protection schema is designed to automatically learn and adapt to changes in the API structure without requiring manual intervention from administrators. This dynamic learning process enables FortiWeb to identify and protect against anomalies and potential threats in real-time.

To forward requests for web application B to a single web server, you would configure FortiWeb to use HTTP content routing and create a server pool specifically for web application B. In FortiWeb, server pools are used to group servers together based on application requirements, and you can configure the pool to contain only a single web server for application B.

In the SVM plot of potential bot activity, you can see that the sample value (orange) is significantly different from the average value (green) and the maximum value (blue) in most of the metrics. This suggests unusual or abnormal behavior, indicating that the connection might be a bot. Typically, botsexhibit patterns that diverge from normal user activity, such as higher frequencies of certain types of requests, abnormal throughput, or an unusual pattern of HTTP requests (such as requests without referers or excessive TCP connections).

The easiest way to allow a search engine indexer (such as Googlebot or Bingbot) to index your website on a FortiWeb is to add the indexer's IP address to the trusted IP list. This ensures that traffic from trusted indexers is allowed through without being blocked or interfered with by FortiWeb's security features like bot protection.

It was upgraded to a different version after initial installation: The device has multiple partitions with different firmware versions (6.4.0 and 6.4.1), indicating that it was upgraded after the initial installation from version 6.4.0 to 6.4.1.

FortiWeb is primarily designed to handle HTTP and HTTPS traffic, protecting web applications from various threats. By default, when operating in reverse proxy mode, FortiWeb does not forward non-HTTP/HTTPS protocols to protected servers. However, administrators can configure FortiWeb to handle non-HTTP/HTTPS traffic differently using the config router setting command. This command allows enabling IP-based forwarding (routing) for non-HTTP/HTTPS traffic. When enabled, FortiWeb can route non-HTTP traffic through itself to the appropriate backend servers. ​

Despite this capability, any non-HTTP/HTTPS traffic that is destined directly for a FortiWeb virtual server IP address is dropped. This means that while FortiWeb can be configured to forward non-HTTP/HTTPStraffic to backend servers, it will not process non-HTTP/HTTPS traffic targeted at its own virtual server IPs. ​

Regarding IPv6 routing, FortiWeb does support IPv6 in various operation modes, including reverse proxy, offline inspection, and transparent inspection. However, enabling IPv6 routing requires specific configurations and is not automatically enabled by default. ​

The best way to limit brute force login attacks on FortiWeb is to configure a brute force login custom policy. FortiWeb provides the ability to detect and mitigate brute force login attempts by automatically limiting the number of failed login attempts within a specific time period. This approach allows you to block or rate limit suspicious IP addresses while still allowing legitimate users access, based on your configuration.
