The global cloud IT market currently accounts for 42.8% of the total IT spending (based on an estimate by IDC) and is set to hit $390 billion in revenues by 2020 (according to a study by Bain & Company). Cloud has revolutionized the world of IT and we are just beginning to scratch the surface. The proliferation of cloud infrastructure comes with its own share of challenges – and one of the most pressing concerns is that of security. A spending projection of $105 billion on security technology by 2020 underscores the magnitude of the threat. Bruce Schneier, well-known security guru has rightly said, “Security is a process and not a product” – because it is not a one-time effort but a continuous endeavour to keep threats at bay and secure the enterprise. This is especially true as attacks become more sophisticated and capable of wreaking unprecedented damage. In this whitepaper, we will outline steps that organizations must take while designing their security policies and sketch a secured reference architecture on Microsoft Azure to better understand how to protect and secure your cloud infrastructure.
