Businesses across all industries understand the advantages of cloud computing. While some enterprises are just getting started with their migration as part of digital transformation initiatives, others are implementing sophisticated multi-cloud, hybrid strategies. The particular risks that come with the technology make data security in cloud computing one of the toughest deployment issues at any level.
Companies of all sizes are migrating to the cloud to benefit from the data redundancy, increased data availability, and considerable cost savings that cloud computing offers in comparison to a traditional data center-based physical infrastructure.
By removing data stores from storage closets and under desks, moving to the cloud can help lessen shadow IT and enable them to be managed and safeguarded in accordance with best practices and legal requirements. In fact, according to an Accenture survey titled “Perspectives on Cloud Outcomes: Expectations vs. Reality,” 95% of corporate leaders today make use of cutting-edge cloud services for their firm.
There is no especially novel methodology needed for cloud data protection measures. Data security in the cloud might resemble data security in a conventional data center. Data protection techniques applicable to cloud computing include encryption, authentication and identification, integrity checking, access control, secure deletion, and data masking.
SaaS data protection
Firms must be prepared to be overwhelmed by the selection of reliable data security choices that can be configured and managed for SaaS in particular.
Since the CSP manages most aspects of data security in SaaS systems, it’s crucial to scrutinize any control reports and shared responsibility attestations. In SaaS systems, logging is either difficult or nonexistent. The use of Cloud Security Posture Management (CSPM) and SaaS Security Posture Management (SSPM) software is sometimes beneficial.
Identity and authentication
The proper implementation and configuration of well-known network, system, and application security methods at various levels in the cloud infrastructure will maintain data security’s confidentiality, integrity, and availability. A wide range of elements that carry out authentication and access control are included in these processes. There are several ways to authenticate people and even communicate systems, but each relies on cryptography.
Users are authenticated in a variety of ways, but they are all dependent on a mix of authentication elements, including something that the person knows (like a password), has (like a security token), or is intrinsically quantifiable (such as a fingerprint). Only one authentication element is used in single-factor authentication. Additional elements are needed for stronger authentication; two-factor authentication, for example, is focused on different authentication aspects (like a pin and a fingerprint).
When an organization employs numerous Content Security Policies (CSPs), one issue with employing traditional identification procedures in a cloud setting arises. Synchronizing identification information with the organization in such a use case is not scalable. When infrastructure is moved toward a cloud-based solution, a new set of issues with traditional identification techniques surface.
Infrastructure frequently uses domain-centric identity strategies that restrict looser alignment, as in partnerships. Federated Identification Management (FIM) is a strong foundation for identity in cloud computing. Federated identity employs a claim-based token approach, which is different from conventional protocols. A federated token approach can still satisfy traditional identification requirements, nevertheless.
Multi-Factor authentication for every cloud
At the very least, all cloud environments should impose a need for Multi-Factor Authentication (MFA) for any privileged users accessing cloud services or carrying out administrative tasks. Any end user that accesses the cloud should ideally be required to provide MFA. Businesses must maintain current permissions and security restrictions and ensure that security precautions are outlined in a cloud security policy.
In order to enable DLP, content filtering, malware protection, and other controls, ideally, all SaaS cloud access should be facilitated through a cloud access security broker, if it is practical to do so. Furthermore, using solutions like CSPM and SSPM can assist firms in closely monitoring data storage settings and exposure.
