NetVision Solution for ISO 27002 / ISO 17799

ISO 27002 (formerly ISO 17799) is a best practice framework for information security. Many organizations use ISO standards as a way to measure the application of information security in a very subjective field. Others leverage the ISO standard as a way to map specific security solutions to larger control frameworks related to information technology (COBIT) or corporate governance (COSO). That mapping provides a measurable way to prove compliance with governmental and industry regulations that have requirements affecting information technology. Often, the real-world application of IT solutions for compliance with regulations is widely open to interpretation. ISO 27002 has given companies a benchmark framework to work within. In summary, ISO 27002 provides three core values:

  • Allows organizations to benchmark their implementation of information security controls.
  • Provides a measurable framework with which to meet governmental and industry regulations that are often open to interpretation.
  • Enables a multi-regulatory approach of implementing information security controls that meet requirements for multiple regulations.

For more information on ISO 27002, visit the International Organization for Standardization (ISO) web site [www.iso.org].

NetVision's support for ISO 27002 primarily lies in the identity related sections of the framework (sections 10 & 11). The table below highlights the primary areas of sections 10 & 11 in which NetVision can directly help implement the practices recommended by the ISO 27002 framework. Sections shaded in gray are not directly applicable to NetVision solutions.
