Effectiveness Measurement : Information Security

Why Measurement of Information Security is so Important and challenging?

In today’s edge, businesses are going global across the world. In this competitive environment, organizations are creating, collecting and receiving lot of information through various channels such as analyzing social media, research, survey, outsourcing business process to another country. Many organizations are dealing with HUGE VOLUME OF INFORMATION rather I would say SENSETIVE INFORMATION.

Today many organizations are investing huge amount to ensure CONFIDENTIALITY, INTEGRITY and AVAILABILITY of such Information.

These investments could be in terms of:
  • Hiring competent people
  • Establish workflow terms of IT as well as INFORMATION SECURITY related processes
  • Procuring secured technology
  • Third party assurance on organization’s INFORMATION SECURITY practices
  • Spending lot of time as INFORMATION SECURITY needs checks and balances
With such huge investment in INFORMATION SECURITY, board of directors are more concerned about the effectiveness of implementation of INFORMATION SECURITY practices to protect SENSITIVE INFORMATION. Such huge investment has NO VALUE if there is no reasonable assurance on implemented practices from an Independent IS Auditor.

Many organizations are now more concerned about the overall “Health of Information Security Management System”. Board of directors are now taking interest in reviewing IS audit findings and showing commitment towards information security. Board of directors are expecting to see the quantities or qualitative analysis with trend analysis.

For an organization’s Information Security Manager, this is becoming challenge to measure the effectiveness of information security. Measurement of process is now common requirement of many international standards such as ISO/IEC27001:2013. Board of Directors might not understand the technicality of information security controls, this creates further difficulties for an Information Security Manages in terms of:
  • What to present: board of directors might not understand all technical jargon. these people are more interested in high level dash board which shows overall analysis in few graphs or statistics.
  • How to present: it would be so foolish to open complete word document or PDF or complete VAPT technical report in front of management. Simple power point presentation would work for them.
  • How much to present: Finally you want board of directors to take key decisions. According to approved measurement approach, you may only want to present TOP 5 or TOP 10 key risks to prioritize risk treatment plan.

 In this entire measurement exercises, information security manager has to play a vital role in defining:
  • Management’s expectations in terms of “Health of Information Security Management System”
  • Information security control metrics
  • Identify metrics owner
  • Define measurement frequency
  • Create meaningful dashboard for management
  • Trend analysis
Once implemented, over a period of 12 to 18 months, both information security manager and board of directors would have reasonable understanding in terms of information security control effectiveness and how these metrics are adding value to their organization.
