Cloud Security in 2021: Key Trends and Strategies

Cloud Security in 2021 Key Trends and Strategies-01

The year 2020 will always be remembered as a uniquely disruptive year, with security events exploding and cybersecurity transforming society in several ways. While the global pandemic continues to linger in 2021, data breaches will also continue to make it to the top of the headlines.

Since personal data is being weaponized as one of the valuable assets in the black market, cybersecurity remains a severe point of contention. This is where cloud security comes to the rescue. However, it has proved to be an arduous task because of critical reasons, including the absence of transparency in the cloud back-end, shortage of semantically preemptive security requirements and lack of reliable taxonomic methods.

With organizations and businesses rapidly migrating their data infrastructure to the cloud environment, they must have a radical approach towards optimizing stacks and creating a flexible cloud-native framework. Here are some new cloud security trends for CISOs to consider in 2021.

Zero-Trust Network Access (ZTNA) Instead of VPNs

A new window of vulnerabilities has opened due to the unforeseen shift to remote operations. Businesses used VPNs and VDIs to ensure real-time threat intelligence and protect critical data. However, these legacy security architectures turned out to be unsuitable for virtual environments. So, security leaders advise businesses not to trust VPNs completely. Here’s where Zero-Trust Network Access comes to light.

ZTNA provides a zero-trust policy, where no user, network traffic, or transaction is trusted unless it is viewed via ZTNA lenses. Meaning, ZTNA moves beyond simple dichotomies and puts trusted and untrusted network traffics within the same network.

Even though ZTNA can certainly improve network security, its proponents have an unrealistically optimistic approach towards the legacy challenges of data being spilled and other security processes pertaining to the ZDNA model. Therefore, having a toolset isn’t sufficient. Organizations should also have a strategy and vision.


Emerging cloud computing platforms are the most innovative tools that add value to programming languages and security enterprises. So, serverless creates security-related opportunities and challenges to stay on top of growing PaaS platforms.

The complexities involved in operating with serverless means that its full potential is yet to be achieved. But, serverless has made the cloud computing landscape more dynamic and robust and will continue to bring in innovative developments and transformations in 2021.

Confidential Computing

Confidential computing helps mitigate some of the cloud security issues, namely vulnerabilities in the underlying cloud fabric, malicious system administrators, and third parties accessing data without authorization. But, with the trusted execution environment (TEE) businesses can reduce exposure of all sensitive data as it’s secured with encryption keys and isolates itself from other software (operating system and cloud service stack). This helps ensure that keys are only accessible through authorized code, and if the attackers try to access without authorization, the TEE directly will deny access.

Confidential computing has gained enormous support across several industries. It is in a better situation to provide high-end solutions that are in great demand for the next wave of cloud adoption.
