Utilising the services provided by the public cloud providers is an effective choice for reducing personal or business costs, which is why both individuals and organisations are resorting to the use of the public cloud services.
For organisations, cloud service providers are offering the opportunity to extend or reduce resources allowing the organisation to only pay for what service is used, for that reason organisations manage to avoid unnecessary hardware costs.
Although, the public cloud services offer solutions to various conventional IT resourcing problems, nonetheless the swift increase in the usage and dependency on the public cloud has initiated scattered distribution of data.
Organisations who choose to distribute data suffer the negative impact which ranges from workloads being spread across incongruent instances to varied platforms. As a consequence, monitoring the changes to workloads, data and architecture is a demanding and difficult task which can result in a cyber security lapse.
Public cloud service providers are only responsible for the security of the cloud i.e the physical datacenters. Thus, consumers whether individuals or organisations remain responsible for the security of their own data and workload.
Many individuals and organisations are unaware of their own responsibilities should a cyber security breach occur with the public cloud. Hackers are well informed about the issues surrounding responsibility and accountability and are prone to take full advantage of any security lapses with various workloads and data.
TechDecoded recommends the followings tips for securing data held on a public cloud:
Implement the relevant security measures required – Ensure firewalls and relevant security measures are in place to protect all technological infrastructure particularly servers. Server security is necessary for prevention of data loss.
Maintain endpoint and email security – Endpoint security pertains to devices. Take precaution to ensure all endpoint devices have advanced system security and ensure email accounts have strong passwords and security measures in place. Device and email security is important to prevent unauthorised access to cloud accounts.
Recognise your cyber security responsibilities – Cyber security is handled in a diverse manner on the cloud. Public cloud providers operate a shared responsibility model which indicates different responsibilities. A cloud provider will take responsibility for security of the cloud and can only be held accountable if there is a problem associated with the security of cloud. In a shared responsibility model the consumer(individuals or organisations) are responsible for the security of any data placed in the cloud. Therefore, a public cloud provider will not take responsibility for any breach of security with a workload or data held on the cloud. Plan effective cyber security of data stored on the cloud by improving the overall cyber security strategy and enforcing stringent policies.14
