The debate on security between traditional data systems and cloud data systems is a serious one, impacting many businesses in their decision to implement or refrain from implementing the cloud.
Traditional IT professionals continue to champion legacy systems for a number of reasons. The argument is that where data is stored onsite, security can be better managed as system checks can be performed at any time.
It is also believed that on-premise data centres allow a quicker response time to data breaches.
While traditional data centres do allow for greater control, close proximity to data does not necessarily correlate to security.
Looking to the future, there are many advantages that the cloud offers businesses. Here in Part 1, three cloud advantages are listed outlining how the cloud is more secure than traditional data systems.
- Automatic backups as part of disaster recovery
Modern data centres are now equipped with an automatic back-up or recovery process, where one system will takeover from a previous system that has failed, and so on.
Another way data is secured in the cloud is through storage. Rather than being stored on a single site, data is spread across multiple locations. This significantly reduces the risk of an attack or data breach.
- Extensive surveillance + tightly controlled access
Top-tiered data centres are known for stringent surveillance and strong perimeters to ensure the data stored is physically protected. Access to data centres is heavily restricted, and background checks / security measures are undertaken when employees, visitors or vendors enter the centre.
Top data centres also include multiple layers of defence, such as high fences, security cameras, barbed wires and security guards to limit physical access. This minimises the likelihood of a breach occurring due to human error.
- Regular auditing + Uptime certification
Cloud Service Providers are required to undergo regular auditing to ensure they are meeting security standards, whereas traditional systems do not have this external check. This means traditional systems potentially run for years without an audit, leaving room for errors and security negligence.
Cloud Service Providers are also characterised by their Tier level awarded by the Uptime Institute. There are four tiers, with Tier IV being awarded to the most sophisticated data centres. A Tier IV centre will have uninterruptible power supply, redundant and diverse connections to the power grid, a standalone building, and backup power generation.
The security measures undertaken by Cloud Service Providers indicate that the cloud offers more security safeguards than legacy systems. In part 2, other methods of security will be looked at, including cloud backup systems, and the expertise of top-notch cyber security professionals.
