The public cloud is based on a standard cloud computing model. Public cloud service providers make resources, applications, or storage publicly available over the internet. Public cloud services can be available for free or on a pay-per-use model. The main benefit is cost savings. Because users do not need to buy, install, operate, or maintain cloud servers and other equipment as if using a private cloud.
However, the problem is that public clouds tend to be less secure from cyber attacks when compared to private clouds. Not a few companies are leaving the public cloud because of concerns about its security. However, given the benefits that public clouds offer, there's nothing wrong with considering them. So, how to make the public cloud more secure from cyber-attacks? Here's the information!
Thoroughly know the security services that cloud providers provide
This can be done by checking the SLA (Service Level Agreement) that you received and making sure that the security guarantee is included in the SLA and that the cloud provider can implement the security guarantee. This is very important to note because if the security services provided by the cloud provider are not clear in the contract, security services are difficult to implement.
There are some important things you should pay attention to. First, how the data will be protected and what encryption policies the public cloud provider uses. Second, what security standards and defenses are in place against security risks. Third, the disaster recovery plan that is owned. Fourth, the process of monitoring and recording cloud activities is used. Fifth, the way the provider handles end-of-business operations and data deletion.
Align internal standards and procedures with cloud providers
When companies partner with cloud providers in an IaaS model, security becomes a shared responsibility. The majority of companies today rely heavily on their cloud providers, considering that cloud providers provide security for enterprise applications and data in their in-house IT group. Internal data and network security must evolve to be consistent with the cloud provider's service offerings.
This means that companies must align their internal security policies to be consistent with cloud service providers as data is moved to the cloud. The company must also evaluate and understand any security gaps between the on-premise system and the cloud environment in which it is used. Implementing procedures to ensure end-users (and administrators) do not create cloud deployments without approval from the IT department should also be considered.
Use hardware and best practices to protect cloud data
Enterprise cloud solutions are often hybrids, a mix of private and public clouds. For hybrid clouds, investment in advanced hardware will add another layer of security to the cloud environment. Security in the cloud must exist in three aspects, namely entering or leaving the corporate network, entering or leaving the cloud provider, and within the cloud itself.
Update security architecture regularly
Regular updates to the security architecture are essential for any cloud environment. In many ways, network security is a moving target and requires constant vigilance. This function can be performed by a third-party security provider or performed in-house within the IT department. If internal IT is unable to provide this service, consider registering a managed security service provider (MSSP).
