T: +6221-39834116 F: +6221-39834114 E: sales@bellua.com Threat #1: Abuse and Nefarious Use • Criminals continue to leverage new technologies to improve their reach, avoid detection, and improve the effectiveness of their activities. • Cloud Computing providers are actively being targeted, partially because their relatively weak registration systems facilitate anonymity, and providers’ fraud detection capabilities are limited. 9

T: +6221-39834116 F: +6221-39834114 E: sales@bellua.com Threat #2: Insecure Interfaces and APIs • While most providers strive to ensure security is well integrated into their service models, it is critical for consumers of those services to understand the security implications associated with the usage, management, orchestration and monitoring of cloud services. • Reliance on a weak set of interfaces and APIs exposes organisations to a variety of security issues related to confidentiality, integrity, availability and accountability. 10

T: +6221-39834116 F: +6221-39834114 E: sales@bellua.com Threat #3: Malicious Insiders • The impact that malicious insiders can have on an organisation is considerable, given their level of access and ability to infiltrate organisations and assets. • Brand damage, financial impact, and productivity losses are just some of the ways a malicious insider can affect an operation. • As organisations adopt cloud services, the human element takes on an even more profound importance. It is critical therefore that consumers of cloud services understand what providers are doing to detect and defend against the malicious insider threat. 11

T: +6221-39834116 F: +6221-39834114 E: sales@bellua.com Threat #4: Shared Technology Issues • Attacks have surfaced in recent years that target the shared technology inside Cloud Computing environments. Disk partitions, CPU caches, GPUs, and other shared elements were never designed for strong compartmentalisation. • As a result, attackers focus on how to impact the operations of other cloud customers, and how to gain unauthorised access to data. 12

Beyond the damage to one’s brand and reputation, a loss could significantly impact employee, partner, and customer morale and trust. • Loss of core intellectual property could have competitive and financial implications. Worse still, depending upon the data that is lost or leaked, there might be compliance violations and legal ramifications. 13

T: +6221-39834116 F: +6221-39834114 E: sales@bellua.com Threat #6: Account or Service Hijacking • Account and service hijacking, usually with stolen credentials, remains a top threat. With stolen credentials, attackers can often access critical areas of deployed cloud computing services, allowing them to compromise the confidentiality, integrity and availability of those services. • Organisations should be aware of these techniques as well as common defence in depth protection strategies to contain the damage (and possible litigation) resulting from a breach. 14
