Phases involved in the Vulnerability Internet Security Test Audit

Frequently ask questions


After we have received your authorization, we start working with you and will conduct the Vulnerability Internet Security Test Audit (VISTA) as soon as possible.  Normally, you will received the finally reports in one to two business days.  

The VISTA does not trigger a Denial of Service because the audit allows for a variable bandwidth load (low, medium, high, and maximum) on the machines it is scanning.  We always conduct the testing using "low"  bandwidth so that there is no inference with your operations.  The VISTA closely monitors the time-response (through RTT, response-time tests) and dynamically adjusts the load appropriately so that you will probably not even notice when the VISTA is conducted.


Through a secure SSL browser based connection we log in to your supplied IP address and scan the active IP addresses.  By supplying these IP addresses we are able to scan and identify all network devices accessible via the Internet.

These devices may include routers, switches, hubs, firewalls, Web servers, mail exchangers, UNIX and NT servers, workstations, desktop computers such as PC and Macintoshes, printers, and other network appliances.

During the analysis phase, the Knowledge Base uses its up-to-date database to test for vulnerabilities.  Multiple sources and methods are employed in updating the Knowledge Base.  These methods include the monitoring of hacking sites and research conducted by our service provider's dedicated engineers.  Our service provider has partnered with Security Focus (the leading publisher of vulnerabilities) to ensure that the knowledge base is fully current.


Once the identification and analysis phase is completed.  We provide easy-to-understand HTML reports that summarize the security of network devices.  At this time, if you are not satisfied with our service, you shall owe us nothing.

We also generate a Management Summary, which contains a global view of the security level of all external network IP addresses and the changes since the last scan.  Sample html reports:
