Many of the traditional IT people still believe that traditional physical infrastructure is far safer than the cloud. But the reality is that cloud is much safer and better. Cloud providers always try to be fully complaint as per the latest security standards which a traditional IT physical architect cannot match.
Around 64% of surveyed IT people are of view that cloud is much more advanced and better in terms of security. For some people denying cloud to be more secure is due to some major attacks on Target, Home depot, and Apple icloud that attracted media’s attention about cloud security.
Though the reality is that all these incidents happened due to human mistake,not that cloud was hacked. Most people including technical are still not aware about the security of cloud technologies.
Let us go through some reasons as to why cloud is much better option as compared to on premises installations, storage infrastructure and traditional methods of computing. Following features will demonstrate why doubts about cloud is a myth
- Highly secured data centres: All cloud providers put strong safeguards to help protect customer privacy. Cloud providers spend countless hours considering threats, planning out physical securities and testing it out to ensure that they can counteract risks involved.
Each data-centre deployed by cloud provider involves planning out location according to weather conditions, redundant networking setup to ensure 24*7 availability in case of maintenances. Each provider works on principle of least privilege policy by allowing access when required with proper justification.
We also need to understand that all providers works on shared responsibility model. Providers take care of only hardware, software and physical facilities provided while customers are responsible for how the services are used.
- Compliant logging services for post-incident forensic investigations: A lot of cloud providers provide services which can be accessed via rest API calls, management consoles and SDKs allowing customers to continuously monitor activities in their cloud account.
- Concept of Principal of Least Privileges: All cloud providers work on the principal of least privileges. Customers can setup different users and separate customized roles as per the access required and attach policies which are needed. This way customers are assured that one user can see only what he is allowed. As an extra line of defence, all user logins can be backed up with multi-factor logins to be rest assured that users are don’t compromised even if password gets compromised.
- Meeting Compliance Requirements: All cloud providers manage dozens of compliance programs and chances are that the one you require are already completed from your cloud provider. Some of the compliances included CSA, ISO 9001, ISO 27001, ISO 27017, PCI-DSS Level-1, SOC-1-2-3 and much more like HIPAA.
Since your cloud provider has got the complaint certificate already, you don’t need to spend extra cost and man hours on being re-complaint for the same.
- Security at just few click away: All clouds do provide network firewalls such as Networks ACLs, security groups for instances to allow / open server ports. Encryption of EBS volumes using Self-managed keys or customer managed keys. Private connectivity options from office to data-centre. AES-256 is the de-facto standard now for encrypting the data with TLS 1.2 security protocol.
As more and more companies are migrating to cloud services, they are receiving tangible results in form of increased efficiencies and better data access whenever it is needed. All these benefits that cloud is offering such as safety, security & convenience and any time data access is removing misconception about cloud.
It will be interesting to note that big data, virtual reality, and internet of Things are gaining limelight now and are working in coordination with cloud.
