Filter Engine Tests

DrawBridge Network Traffic Control analyzes HTTP requests in a variety of ways to protect devices and entire networks.

A. Category Classifying

Dynamic Classifying

Dynamic classifying of the page response body is the core of DrawBridge filtering.

Clicking the button below should block as Sports, since the page is about baseball.

URL Blacklists

URL Blacklisting enables the blocking a link, based on properties such as domain, subdomain, or the entire URL. (Blacklists are not used heavily, as they tend to go stale quickly.)

The example below should be blocked in the Gambling category.

RTA Metatag

The publisher of a page may include metatag labels of various types indicating that the page should be restricted to adults.

The DrawBridge filter checks for this label and blocks the page if it is found.

RTA Header

For resources other than pages, the content publisher may include a label in the HTTP Response Header that the request should be restricted to adults.

The DrawBridge filter checks for this header and blocks any request if it is found.

B. Malicious Traffic Detection

TLS Cert Inspection

Servers of malware, trojans and other malicious content may be identified by properties in the TLS Certificate.

The DrawBridge filter checks such attributes and does not complete the handshake when they are found.

To test, click the button below. Since the connection to server will be blocked, no block page will be shown.

Virus Scanning

Viruses can be downloaded from web servers. They're not only sent via email.

Antivirus scanning of HTTP downloads is an optional service available on some systems. Contact Compass Foundation if clicking the link below downloads a zip file rather than the block page.

C. Deep Scan Page URLs

Scam Domains

Pages are known by the company they keep - a page that is linked to other popular pages is more likely to be reliable.

Pages that link to known scam domains may contain other deceptive elements. Click the button below to demonstrate blocking pages that link to fraudulent domains.

Phishing URLs

Phishing URLs load pages designed to impersonate other services, such as bank accounts, email accounts and so forth.

If a user clicks these URLs and proceeds to log in, the publisher of the page is able to steal the credentials.

Homoglyph Attacks

A homoglyph attack domain name with alphabetic characters from other languages that resemble characters in English.

Which domain belongs to the computer company - аpple.com, or apple.com? The human reader can't easily differentiate.
