ISO 27400 Lead Manager case studies

ISO 27400 Lead Manager · Put your knowledge to work in context.

The ISO/IEC 27400 Lead Manager credential is offered through PECB's training and certification programme, where ISO/IEC 27400 sits in the Information Security group of the Cybersecurity catalogue. ISO/IEC 27400 is the international standard giving guidance on information security controls for Internet of Things (IoT) systems, so a "Lead Manager" role here means the person who directs an organisation's IoT security programme rather than a device-level engineer. The ISO 27400 Lead Manager case studies are 5 cases and about 3,892 words.

Asset records are unreliable: the CMDB lists 22,000 'connected devices', while the OT team estimates 31,000, including 6,000 sensors on a 2016 line, 900 IP cameras and 240 cellular routers installed by a systems integrator.

An electricity distributor operates 60,000 smart meters with a 15-year service life. Of these, 8,000 are an older model whose radio module cannot accept over-the-air firmware images larger than 32 KB, and the vendor has announced end of support in 18 months.

A green dashboard during a seven-week retail compromise

A retail chain has 1,200 stores, each with 12 IP cameras, a smart HVAC controller and a store hub connecting to a central video platform. The security team's monthly dashboard reports 98% of cameras on the latest firmware, 99.6% patching compliance and zero open critical vulnerabilities.
