Nowadays more and more businesses are adopting cloud to run its IT due to the emergence of multiple hybrid environments. Data is the fuel for today’s organizations which is the driving force for quick and timely business decisions. However, the big question is how secure is our data on the cloud? It has become crucial to protect it from unwanted sources who are always on prowl.

Cloud technology has made the management of data very easy and with multiple layers of security to protect data from snoopers but still it is important to understand the key difference between traditional IT security and cloud security so that business can make an informed decision as to what is best suited to them.  

Today we look at major differences between Cloud security and traditional IT security approach , how traditional IT threats and cloud threats are being handled , advantages / limitations etc.

About Cloud Security 

Cloud security is all about granting access on demand. It closely follows the infrastructure as a service (IaaS) model which means you will be able to move your data on a service provider cloud which is a trusted third party.

Cloud computing security is a set of controls based on technologies and policies which are designed to adhere to the regulatory compliance rule set, and protect information, data, applications and infrastructure related to cloud computing usage. 

Challenges of Cloud computing

  • Trust someone else to take care of your data 
  • Increasing risks of cyberattacks in spite of stringent security measures claimed by cloud providers
  • Insider risks are high as if cloud account is compromised so is the data of customer

About Traditional IT Security 

In Traditional IT frameworks businesses need to procure , install, maintain IT devices on premises. On front of security, you adapt a plan for your data security and decide what security devices you are willing to buy , manage and monitor to defend your IT infrastructure be it firewalls, Intrusion detection/ Intrusion prevention systems, Antivirus etc.

Traditional approach gives more control over how each device is used. Costs of installation and maintenance are the biggest drawback of traditional systems. As more data grows more equipment needs to be purchased which calls for more resources to manage so running costs are high. 

Challenges of Traditional IT Security 

  • Cybersecurity stacks are costly, complex and resource demanding 
  • High upfront costs
  • Longer time to market
  • Slow adaptation and limited scalability

Comparison Table: Cloud security vs Traditional IT Security 

Below table summarizes the difference between the two:

ConceptCloud computing security refers to procedures, technologies, policies and controls which come together to protect information on cloud-based infrastructure.Traditional IT security refers to rules and tools in place together to protect security and accessibility of network and systems inclusive of both hardware and software such as firewalls, VPNs , Antivirus software in addition to physical security measures.
ApproachApproach is centralized management of security which is capable for protection of sensitive data , support for compliance efforts and establishing authentication rules.i) Approach is decentralized.
ii) Perimeter security , insider security all facets required to be addressed.
Locationi) Handled by third party data centres and outsourcing depends of selected model be it LaaS , PaaS and SaaS.
ii) Security is anywhere as you can access your files anywhere.
In Premises data centres where everything is managed internally be it physical or logical or people related.
ScalabilityQuickly scalable as everything is a service be it hardware, software, applications, storage.Requires extensive planning and investment to scale up.
UtilizationEffective utilization of resourcesEfficiency is lower
PricingPay-as-you-go model.
Based on usage of resources on cloud infrastructure.
Higher costs as everything is to be maintained internally starting from security hardware, applications including monitoring costs.
ResponsibilitySecurity is responsibility of both organization as well as service provider providing softwareSecurity is entirely on organization hence more burden on IT teams
AutomationCloud security is highly automated using APIs etc.Mostly traditional approach to handle security require lot of manual efforts.
Specialized optionsCloud security can offer more specialized solution based on business need which otherwise be out of reach due to costs.Separate and costly security tools needed to protect each layer of enterprise why may be beyond the budget of business.
