Can your Network be easily compromised? Is your Internet vulnerable? You might want to perform some tests on the Quality of Service your Internet Service Provider – ISP is providing you. It can also be more dangerous if your ISP is also your router vendor! One of the fast and reliable tools which I would propose is the ICSI Netalyzr tool which tests your internet connections for signs of trouble and provides you detailed report vulnerabilities, latency, and several tests. The test can be performed by almost anyone with just a simple click.
“ICSI Netalyzr is a service maintained by the Networking Group at the International Computer Science Institute, an affiliate with the University of California, Berkeley and funded by the National Science Foundation. The service got some publicity and found importance after late 2007 when Comcast was sued for throttling Internet traffic which Comcast later admitted being true.” – freewareGenius
The report consists of:
- A summary of the Noteworthy Events
- Addresses-based Tests
- Reachability Tests
- Network Access Link Properties
- HTTP and DNS tests
- IPV6 tests and Network Security Protocols
- Host Properties
I made several tests myself and notice that many routers are vulnerable to attacks. One of the tests I made from a Netgear router DG series intentionally downgraded with an old firmware from the official website of Netgear was found to be vulnerable. Click here on this link to access to the Netalyzr tool. I would, however, recommend you to use DD-WRT or OpenWRT for best QoS.
You could also check for DNS resolution, Latency issues and Measurement of your Network buffering capacity. You would need to authorize your browser to access a JAVA plugin to be able to perform the test.
You can also perform your test using the Android App as well as on the Netalyzer command line client.
