These three lines of defense are silly. There is only one line of defense, it's the first line. Defense defined the action of defending from or resisting attack. The second and third lines don't do any defending. The second and third lines are passive and only come into play after a cyberattack has occurred.

Strengthening Organizational Resilience Through Aligned GRC Roles As organizations navigate an increasingly complex risk landscape, the importance of effective Governance, Risk, and Compliance (GRC) practices cannot be overstated. The three lines of defense model provides a robust framework for aligning GRC roles and responsibilities to build organizational resilience. The first line of defense comprises operational roles such as the Operations Manager, IT Administrator, and Department Heads. These roles are responsible for implementing and executing risk controls, managing day-to-day access controls, and owning the risks within their processes. The second line of defense includes roles like the Compliance Officer, Risk Manager, Security Manager, and Data Privacy Officer. These individuals develop and monitor compliance policies, identify and assess enterprise-wide risks, ensure information security, and oversee data protection regulations. The third line of defense consists of Internal Auditors, IT Auditors, and the Audit Manager. This line provides independent audits of controls and processes, evaluates IT general controls, and ensures alignment between audit programs and organizational goals. By aligning GRC roles across these three lines of defense, organizations can foster a culture of accountability, enhance risk management, and drive continuous improvement. This holistic approach empowers teams to work collaboratively, leverage their unique expertise, and collectively strengthen the organization's resilience. #GRC #RiskManagement #Compliance #AuditManagement #OrganizationalResilience
Good insight Mark E.S. Bernard, CISO, CIO, PSCO, PM, Architect, Chairman. The 2LoD and 3LoD are post-mortem. 🤓

1moThe actual perspective is 2LOD is Risk Management, 3LOD is Internal audit function. 2nd line evaluation is necessary to oversee the operations before you decide controls are working as expected. 3rd line is audit and tests for design and operating effectiveness. Despite all these activities if a cyber attack has taken place then all lines are responsible. It is wrong to say that only 1st line of defense is enough. This view is indeed silly :-)
