What is Cloud Workload Protection?

With organizations increasingly focusing on cloud-based architectures for their business operations and customer experience, security and compliance have become non-negotiable. However, the challenges in managing the distributed environments and highly vulnerable networks handling the cloud interactions make clouds an appealing target for cyberattacks. IBM corroborates this in its latest report, in which it attributes 33% of cloud-aimed attacks to phishing and 39% to business email compromise (BEC).

Yet, business leaders can only fulfill their cloud ambitions, including harvesting the benefits of generative AI and automation, by opting for unyielding security for clouds. In this scenario, Cloud Workload Protection (CWP) can be a big help.

CWP allows organizations to have a level of security that not only endures evolving cyber threats but also counters them. Ignorance about CWP can mean leaving cloud environments with an extended attack surface, higher chances of compliance failures, and, ultimately, irreparable damage to the organization’s brand reputation.

Therefore, in this blog, we will help you understand everything about CWP, from its definition to how you can successfully implement it for your cloud infrastructure.

What Is Cloud Workload Protection?

Cloud workload is the collective name for various entities situated in the cloud, such as applications, data assets, containers, and more. These help the operations running on the cloud throughout the software lifecycle. Cloud Workload Protection (CWP) is the security approach that can help businesses secure these cloud workloads across cloud environments.

The aim of CWP is to ensure that the cloud environments are continuously monitored so that any potential threats or deviations from desired security guidelines are proactively detected, investigated, and neutralized. This also allows security teams to have deep visibility into the cloud infrastructure (be it multi-cloud, hybrid cloud, or any other) to ensure 360-degree protection that is both dynamic and scalable.

Why is Cloud Workload Protection Important?

Traditional security resources follow what is called a castle-and-moat approach. It’s where you build a parameter around the entity to be secured so that the attackers can’t access it. However, this approach can be too restrictive for a decentralized and distributed environment like a cloud.  Cloud workloads are always interacting with each other, and a “moat” around them would slow down these interactions.

Cloud workload protection, more than anything else, empathizes with the dynamic nature of cloud infrastructure. Therefore, it aligns well with its security coverage needs, visibility nuances, and scalability expectations. With the right Cloud Workload Protection Platform (CWPP), organizations can ensure real-time threat detection and response, essential for stable and reliable cloud performance.

Key Components of Cloud Workload Protection

The blueprint for CWP is motivated by its promises of aligning well with clouds’ distributed nature while being proactive in threat detection and response. This gives us a list of certain fundamental components that CWP cannot function without.

• Visibility: It is highly important that cloud workloads are visible across cloud environments, whether multi-cloud, hybrid cloud or any other cloud infrastructure. Implementing CWP demands proper means to gain insights into cloud data, applications, VMs, and more for real-time monitoring and response strategies.

• Vulnerability management: Proper security management requires that the security teams and admins be empowered with easy means for identifying, classifying, and prioritizing vulnerabilities. CWP needs reliable vulnerability management offerings to ensure that vulnerabilities like misconfigurations can be managed before deployment.

• Real-time protection: Modern runtime threats are too time-sensitive, and a delayed response can be highly damaging. Attackers can quickly traverse interconnected workloads and siphon sensitive data. CWP must have real-time protection features that can vigilantly flag any suspicious behavior among the cloud workloads and respond immediately if a threat occurs.

• Micro-segmentation: Micro-segmentation is a security approach that breaks the network into multiple isolated and more manageable zones. Cloud workloads are susceptible to unauthorized access, which can completely sabotage their operations. However, micro-segmentation limits the damage that can be caused even if an entry point into the cloud is compromised. Therefore, it becomes another essential component of CWP.

• CI/CD Alignment: Any enterprise-grade solution needs to align with the continuous integration and continuous delivery (CI/CD) pipeline to ensure that the agile and automation-friendly operations of the software lifecycle are not disrupted. CWP, too, needs to integrate well with the DevOps workflows to offer meaningful security features.

Common Threats Facing Cloud Workloads

While the convenience of cloud infrastructure fast-tracked the adoption of a lot of modern techs like generative AI and hyper-automation, it also left the environment (and, therefore, the organizations) exposed to many external and internal threats. This is why the cloud security market is huge. It was valued at over $37 billion by recent market reports. Here are some of the major threats that encourage this market and demand intervention from security models like CWP.

• Misconfigurations: Improper setup or abstraction of cloud infrastructure can lead to a lot of security vulnerabilities for the cloud workloads. Inappropriate access permissions, hard-coded secrets, loosely configured APIs, and more such configuration errors practically invite threat actors to exploit them for security. A good example of this is the recent cyberattack on Capita’s data, which was attributed to an exposed Amazon S3 bucket. The ransomware attack is a prime example of how a resource left for overly permissible access can serve as a gateway to attackers.

• Insecure APIs: APIs are indispensable for cloud environments thanks to their fundamental contributions to communication. However, their direct access to cloud workloads can be leveraged by attackers to serve their malicious means. The cyberattack on PandaBuy, an e-commerce organization, was the result of exploitation targeting security flaws in one of the APIs they were using.

• Supply chain attacks: Attackers can easily target third-party tools or applications that businesses might engage in without checking certain security-related details. An improper software bill of materials (SBOM), for instance, might hide certain dependencies that can be exploited by malicious practitioners. The SolarWinds cyberattack in 2020 is a prime example of software supply chains being exploited for vulnerabilities.

• Insider threats: Insider threat is a broader term that might encircle the other threats mentioned in this list but stemming from insider access privilege. Actors within the organization can knowingly or unknowingly expose cloud workloads to security risks that can lead to damaging attack incidents. A recent example of this was an incident in Singapore in which an angry ex-employee deleted critical business data in retaliation for his job termination. The incident is a classic example of unchecked access privilege.

Challenges in Securing Cloud Workloads

We now understand the threats to cloud workloads. However, even with the best intentions, securing cloud workloads is not a cakewalk. Their scalability, dynamic nature, and DevOps-driven performance can easily leave the security teams blindsided. Here are some challenges that make cloud workload security complicated.

• Shared responsibility: Cloud environments, especially hybrid or multi-cloud environments, have multiple teams and entities handling them for different operations. This shared responsibility often leaves gaps in accountability from a security perspective, making it more challenging to cover all the fronts for cloud workload security.

• Dynamic workloads: The applications, data, network, and other cloud workloads themselves are dynamic. They must be flexible to traffic demands, user experience needs, and performance quality requirements. Such dynamism makes it difficult for security teams to keep up with traditional security models.

• Integration challenges: Compatibility issues might often create roadblocks when integrating different security tools for monitoring, investigation, and response. This creates challenges in real-time detection and response related to cloud security incidents.

• Resource limitations: Securing cloud workloads requires skilled teams, competent tools, and essential technologies. Managing them with prioritized vulnerabilities and internal organizational constraints can be challenging.

• Compliance challenges: Dealing with the cloud often leads to managing workloads in different geographical locations, each with its regulatory norms. Compliance management can be difficult for security teams if they don’t strategize for it mindfully.

Best Practices for Cloud Workload Protection

For reliable cloud workload protection, organizations need to adopt practices that align with real-time threat detection, proactive security responses, and deeper visibility into cloud environments. Here are some practices that make sure of all this:

• Automated threat detection: Cloud environments handle large data volumes that cannot be handled by manual security operations. Automation tools for threat detection make sure that critical cloud workloads are constantly and vigilantly monitored for any security-related deviations like unusual login attempts, bulk data transactions, sudden high network traffic, and more.
• Priority-based vulnerability management: Prioritizing vulnerabilities makes the entire security apparatus less overwhelmed. Vulnerabilities can be prioritized based on their severity, potential impact, and likelihood of exploitation, among other factors. Prioritizing vulnerabilities also helps contextualize the CWP strategies for more customized security efforts.
• Unyielding access control: CWP solutions must offer zero trust in access controls. Strict role-based access and least privilege policies can help limit the exposure of cloud workloads to malicious attempts.
• Mindful configuration management: Configuration management needs to be cognizant of security priorities. Automated tools for configuration management need to abide by security and compliance standards, including data protection, logging, and adherence to regulations like the Global Data Protection Regulation (GDPR), Service Organization Controls (SOC) 2, and more.
• High visibility: Without clear insight into cloud applications, data, Application Programming Interfaces (APIs), and other cloud workloads and the activities related to them, any CWP strategy is practically useless. High visibility into the workloads helps with centralized monitoring, proactive threat detection, and vigilant telemetry among other benefits.

How Cloud Workload Protection Integrates with DevOps

The security offerings by CWP need to be embedded throughout the software development lifecycle to ensure that the software solution is remediated for any security issues before deployments. This mandates that CWP integrate seamlessly with DevOps and, in turn, CI/CD pipelines. Here’s what that entails:

• Integration with CI/CD pipelines: First and foremost, the CWP solutions must integrate with the CI/CD pipelines to ensure that automated security checks can be implemented for code build, code testing, and code integration, among other aspects of the software lifecycle.
• Automated vulnerability scanning: To ensure that the CWP processes don’t disrupt the CI/CD workflows, the vulnerability scans must be automated. Continuous examination of the application code, containers, IaC templates, and other cloud workloads would help align the security process with DevOps.
• Shift-left security: To ensure that security vulnerabilities are detected and remediated before deployment, CWP must pull in the security processes during the initial stages of the software lifecycle. Offering shift-left solutions, CWP ensures early detection of vulnerabilities like insecure APIs, hardcoded secrets, or outdated dependencies during the build phase itself.
• Runtime protection for deployments: A DevOps-aligned cloud workload security must also ensure constant vigilance over the workloads to proactively eliminate runtime security issues. To avoid risks like privilege escalation or container breakout, CWP solutions must bring security features for runtime protection.
• Role-based access control (RBAC): While automated security checks can protect the CI/CD pipelines, they are also necessary to protect any potential security lapses caused by DevOps teams. Therefore, for CWP to truly integrate with DevOps, its role-based access control features must limit DevOps teams’ access to critical cloud workloads.
