Security Business Challenges

-

 

TENSION BETWEEN SECURITY AND PRODUCTIVITY

  • Security and productivity are often diametrically opposed
  • Security measures tend to drive up costs, slow down progress, and add steps
  • Vendors often claim their security technology is seamless and invisible to users, but it requires installation, upgrades, and operation
  • It is almost impossible to add security to an enterprise without impacting productivity in some way

MAXIMUM ALLOWABLE RISK

  • Cutting the security budget and balancing security capabilities against risks encompass the concept of maximum allowable risk (in other words, how much security risk is acceptable?).
  • Enterprises use metrics (such as probes, attacks, and intrusions), in part, to show management how the security risks are being stopped/mitigated
  • Metrics help everyone understand how close the enterprise is operating to a potential cybersecurity disaster.
 
SECURITY EFFECTIVENESS OVER TIME
  • An enterprise’s security posture effectiveness is not static and is subject to factors within and outside of its control
  • Emerging vulnerabilities, setbacks, and mistakes impact security effectiveness
  • Audits/projects identify and remediate security program issues.
 
SECURITY TOTAL COST OF OWNERSHIP
Total Cost of Ownership (TCO) consists of multiple cost components
  • –Installing, maintaining, and operating enterprise security controls 
  • –Maintaining/initiating an incident response capability and restoring normal operations 
  • –Remediating lost productivity due to not having necessary privileges, requesting access, or processing policy exceptions

SECURITY TOTAL COST OF OWNERSHIP

Prevention Security Profile vs. Detection and Response Security Profile 
  • Prevention suggests large numbers of security controls resulting in large amounts of lost productivity due to requesting permissions, re-certifying accesses, and interacting with security controls.
  • Detection and response suggest the enterprise will have cheaper controls and less lost productivity due to fewer personnel maintaining firewall rules or re-certifying accesses permissions, but they will require more incident response resources. 
  • It is important for an enterprise to consider TCO when evaluating its cybersecurity program.

Most have cut back on traditional marketing due to costs. But that just drives down your sales.
