BLOG: What Is Cloud Security?

Cloud security describes a form of cybersecurity that covers policies, practices, and technologies for protecting cloud computing systems. Cloud security acquires cloud-stored data and additional digital assets against data breach, malware, distributed denial of service (DDoS), hacking, and other cybersecurity threats. It is also referred to as cloud computing security. Cloud computing is the delivery of hosted services, including software, hardware, and storage, over the Internet.

Cloud computing is now essentially universal among organisations and institutions of all sizes, there are countless benefits of rapid deployment, flexibility, low up-front costs, and scalability. Cloud security is a liability that is shared between the cloud provider and the customer.

The security responsibilities that are always the providers are related to the safeguarding of the infrastructure itself, additionally, patching, and configuration of the physical hosts and the physical network that the compute instances run on and the storage and other resources reside.

The security responsibilities that are always the customer’s include managing users and their access privileges (identity and access management), the safeguarding of cloud accounts from unauthorized access, the encryption and protection of cloud-based data assets and managing its security posture (compliance).

Types of Cloud Ecosystems

Cloud ecosystems delve into three categories: public, private or hybrid. Each of these cloud models shares computing resources across a network and enable the delivery of cloud-based services.

Public cloud

A public cloud can deliver and support technology services via the public internet through a third-party cloud service provider. Public cloud access is supplied via a subscription, consumers gain access to this cloud through payment to the service provider to maintain information or host services on the cloud network.

Many corporations choose to use the public cloud because it offers the ability to scale quickly with minimal investment and maintenance costs. Through using a public cloud ecosystem can save institutions and organisations money, however, it sometimes compromises privacy and control. This is based on the multi-tenancy of a public cloud. The public cloud is a shared resource, a breach with one “tenant” could spread to others throughout the cloud. Each user’s security is reliant on their security strategy, the cloud service providers and also on those using the same cloud.

In theory, relying on a public cloud to manage or process personal data, financial information, anything that involves sensitive information is not advised. Cloud providers are responsible for the security of the cloud, the customer is responsible for security in the cloud; this also includes their applications, identity management, data and encoding and encryption.

Private cloud

Private clouds provide the same objective and function as public cloud, however, they provide cloud infrastructure for limited use by institution or government being. Due to the exclusivity of the private cloud not being shared with any other handlers, this type of network tends to offer far greater control, privacy and security, this being as long as the user has implemented a comprehensive security strategy specifically designed for the cloud.

Private clouds are the ideal solution for organisations needing to follow meticulous compliance obligations or organisations that require extensive management and intricate control over their data. Government agencies, financial institutions, healthcare service providers and other large organizations that collect or store customers’ data should generally use private clouds to conduct business.

Previously, private clouds were preserved and controlled by the end-user and traced from the company’s on-premises IT infrastructure; current day private clouds are a lot more adaptable. Due to the adaptability and flexibility, private clouds can be managed by businesses, a third-party service provider or a combination of the two.

Hybrid cloud

Hybrid clouds merge components of private and public clouds to create a single IT environment. The vital element in a hybrid model is that both private and public elements are seamlessly integrated into a single view, allowing the organisation to monitor and review all activity from a central location.

The hybrid cloud model allows organisations to leverage the cost savings of a public cloud while maintaining a higher level of security for select functions through a private cloud. For example, in a hybrid model, a company can leverage a public cloud for high-volume, low-risk activity, such as hosting web-based applications like email or instant messaging, while a private cloud can be reserved for functions that require more security, such as processing payments or storing personal data.

Why Is Cloud Security Important?

Despite the countless benefits of cloud security, there are also disadvantages, for instance, users of the cloud can access cloud environments from wherever location with an internet connection, but this also provides cybercriminals and adversaries with the ability to.

For businesses shifting to a cloud-based model, security is a top concern. Businesses must construct and implement a comprehensive security solution to protect against an increasing assortment of threats and progressively more complex attacks within the cloud environment. Traditional security strategies expected to protect on-sites hosted networks and associated assets must be amended and modified in order to address the threats related to the cloud environment.
