Executive summary
Cloud data centres, including cloud edge architectures, have become pervasive worldwide as a critical infrastructure
sector for providing network ICT services and applications. The protection of this infrastructure from cyber security
threats by instituting effective risk control and enhanced resilience has received the global attention of governmental
authorities and industry organizations [i.1] to [i.19]. The present document addresses this protection challenge by
providing guidance on individually applying the most current version of the Critical Security Controls for effective
cyber defence [i.20] to cloud infrastructure. For compliance purposes, the Critical Security Controls have mappings to
almost every known government and industry cyber security framework with extensive implementations for diverse
operating systems and applications [i.22] and [i.23]. Included in the present document is a mapping to Cloud Security
Alliance Security Controls framework together with an enumeration of known Cloud Data Centre OS Hardened Image
implementations.

Introduction
The Critical Security Controls are a prioritized set of actions that collectively form a defence-in-depth set of best
practices that mitigate the most common attacks against systems and networks. Under the auspices of the Center for
Internet Security (CIS), the Controls are developed by a community of Information Technology (IT) experts who apply
their first-hand experience as cyber defenders to create these globally accepted security best practices. The experts who
develop the Controls come from a wide range of sectors including, retail, manufacturing, healthcare, education,
government, defence, and others. While the Controls address the general practices that most enterprises should take to
secure their systems, some operational environments may present unique requirements not addressed by the Controls.
The Controls started as a grassroots activity to i
