a second module, for executing network testing procedures on the network to generate therefrom test results adapted for assessing network security, wherein at least a portion of said network testing procedures are automatically selected for execution on the network based on at least a portion of said customer responses to said questions;
a third module, for determining, using said information and said test results, if said network has associated with it a network security vulnerability; and
a fourth module, for generating security recommendations based upon any determined network security vulnerabilities.
2. The apparatus of claim 1 , said software tool further comprising:
a fifth module, for generating a customer qualification form using qualification questions stored within a first database, said customer responses to said questions including customer responses to said qualification questions.
3. The apparatus of claim 2 , wherein:
said fifth module, in response to said customer responses to said qualification questions, generating a customized questionnaire using at least some of a plurality of survey questions stored within a second database;
said customer responses to said questions including customer responses to said survey questions.
4. The apparatus of claim 1 , wherein:
said second module executing said selected network testing procedures in response to customer question responses indicative of a vulnerability.
5. The apparatus of claim 1 , wherein:
said third module analyzing a network and its elements to determine additional vulnerabilities, mapping a network architecture, and providing an inventory of network elements;
said fourth module generating additional security recommendations based upon any additional vulnerabilities.
6. The apparatus of claim 1 , wherein:
said fourth module compares said information adapted for assessing network security to information within a vulnerability database to identify network security vulnerabilities.
7. The apparatus of claim 6 , wherein:
said vulnerability database specifies network security vulnerabilities according to a common vulnerabilities and exposure (CVE) dictionary.
8. The apparatus of claim 6 , wherein:
said vulnerability database comprises at least one of a publicly available vulnerability database and a local database.
9. The apparatus of claim 8 , wherein:
said publicly available vulnerability database comprises at least one of the ICAT Metabase and the Computer Emergency Response Team (CERT) database.
10. The apparatus of claim 7 , wherein:
said vulnerability database associates each specified network security vulnerability with at least one corresponding security recommendation;
said fifth module retrieving from said vulnerability database said security recommendations corresponding to identified network security vulnerabilities.
11. The apparatus of claim 1 , wherein:
said fourth module generates a security rating.
12. The apparatus of claim 1 , wherein:
said fourth module generates a security analysis table for correlating security threats, security mechanisms, security planes, and security layers.
13. The apparatus of claim 1 , wherein:
a network security model is used to adapt the operation of at least the third and fourth modules.
14. The apparatus of claim 13 , wherein:
said network security model classifies the functions of each of a plurality of network elements, protocols and services according to respective ones of a plurality of security layers, each of said security layers responsive to at least one of a plurality of security mechanisms adapted to mitigate network security threats;
said network model associates each classified function with at least one of a plurality of security planes, each of said plurality of security planes included within each of said plurality of security layers;
said network model enables identifying of the vulnerability of each function for each security layer and security plane associated with said function.
15. The apparatus of claim 1 , wherein:
said fourth module generates a report listing said network security vulnerabilities.
16. The apparatus of claim 15 , wherein:
said report includes security recommendations derived from a vulnerability database that specifies network security vulnerabilities according to a common vulnerabilities and exposure (CVE) dictionary.
17. The apparatus of claim 4 , wherein:
said selected network testing procedures are configured in response to at least one of said customer responses to said qualification questions and said customer responses to said survey questions.
18. The apparatus of claim 1 , wherein:
said fourth module generates a security assessment indicative of a percentage compliance with group of best practices.
19. The apparatus of claim 1 , wherein:
said customer interacts with said tool and receives said security recommendations via a common interface.
20. The apparatus of claim 14 , wherein:
said plurality of security planes comprises an end user security plane, a control security plane, and a management security plane;
said plurality of security layers comprises an infrastructure security layer, a services security layer, and an applications security layer; and
said plurality of security mechanisms comprises an access management mechanism, an authentication mechanism, a non-repudiation mechanism, a data confidentiality mechanism, a communication security mechanism, an integrity mechanism, an availability mechanism, and a privacy mechanism.
21. A computer readable storage medium storing instructions which, when executed by a processor, perform a method for assessing network security, the method comprising:
receiving, from a customer, information adapted for assessing network security, at least a portion of said information comprising customer responses to questions;
executing network testing procedures on the network to generate therefrom test results adapted for assessing network security, wherein at least a portion of said network testing procedures are automatically selected for execution on the network based on at least a portion of said customer responses to said questions;
determining, using said information and said test results, if a network has associated with it a network security vulnerability; and
generating security recommendations based upon any determined network security vulnerabilities.
