CWPP role: As a part of a CNAPP, cloud workload protection platforms (CWPP) play a vital role in securing cloud-native environments by focusing on workload visibility, threat detection, and runtime protection.
What is cloud workload security?
Cloud workload security, also known as cloud workload protection, safeguards workloads as they move across cloud environments through monitoring, access controls, encryption, and segmentation.
Workloads can hold application code, PII, business secrets, and intellectual property. Bad actors can gain unauthorized access to these resources using hardcoded API keys and secrets, overprivileged access, and unpatched applications.
Threat actors primarily target cloud workloads because they hold the key to the wider application that the workload belongs to, including data and network connections between the user and the software.
Although cloud providers offer security controls to protect workloads, they have limitations. Additional workload security is necessary for comprehensive protection.
Some of the strongest benefits of cloud workload protection include:
Protecting your sensitive information from unauthorized access, data breaches, and DDoS attacks while empowering you to maintain data integrity with confidence.
Aiding compliance efforts with various regulations, or to meet standards within a specific industry.
Bolstering your security posture by protecting data end-to-end and minimizing risks.
Providing a holistic view of assets and resources for efficient monitoring and incident response.
Ensuring security best practices are implemented, such as IAM and RBAC, to limit illegitimate exposure to cloud resources.
Introducing automation which can reduce human risks and enhance threat detection and remediation.
Centralizing workload management regardless of how diverse your cloud environment is.
Reducing the complexity of working with different cloud environments.
Avoiding business disruptions from security threats and bad actors so that you can move ahead with your growth strategies.
Hackers can compromise cloud-native applications through several tactics that exploit common attack paths, such as:
Threat
Description
Illegitimate access to workloads
Attackers are moving away from brute-force attacks on enterprise applications. Instead, they rely on stolen or compromised credentials to access resources illegally. To combat this, security teams need strong access control policies while enforcing strict secrets management.
DDoS attacks to trick your defense system
A DDoS attack involves overwhelming applications with such a high volume of traffic that it forces the system to fail or malfunction. Cloud workloads are especially susceptible to these attacks as they are exposed to a much wider global user base than a traditional client-server application.
Malware and ransomware for extortion
Cyberattackers could introduce malware or ransomware within cloud workloads through misconfigurations or vulnerabilities. These types of attacks involve hijacking of systems to hold organizations ransom.
Misconfiguration of security controls
If your security settings aren’t configured carefully, it can eventually lead to data breaches and application outages. Misconfigured credentials, access controls, or firewalls work to the advantage of hackers.
API and interface vulnerabilities
As much as APIs help accelerate cloud application development, they can add complexity and become another cause of security vulnerabilities. Insecure APIs can allow bad actors into a system, and the result can be a ripple effect if the system is well-connected using APIs.
Using insecure supply chain resources
Using third-party components and code blocks always pose threats to cloud workloads. They can allow backdoor entry for cyber threats to introduce malicious code and other vulnerabilities into the system. With the prominence of open source tools, this is a growing risk in the cloud-native ecosystem.
Components of a cloud workload that need to be secured
Securing cloud workloads involves a comprehensive strategy extending across the cloud environment. The key target areas for cyber attackers include:
Cloud management consoles: These consoles allow you to control how your cloud environment operates through administration rights, configuration settings, usage monitoring, and billing management. Since it can be the focal point of your entire cloud operations, threat actors frequently attempt to breach the cloud management console.
Virtual infrastructure: Attackers could target your virtual infrastructure, such as your virtual servers, through third-party tools such as Ansible and Chef. To avoid these kinds of attacks, you must secure access to automation tools through robust access control strategies.
Hardcoded secrets: When developers store their applications in public repositories, they often leave access keys, tokens, and SSH keys within the applications. Hackers use these keys and try to gain illegal access to APIs, which have direct access to cloud servers. You need to remove secrets and keys from the application code.
DevOps console: Along with a cloud management console, you must secure DevOps consoles and all the tools you use to manage your CI/CD pipelines. In most cases, these can be in your cloud vendor platform and should be secured and monitored.
For adequate protection of your cloud workloads, follow these best practices:
1. Automate cloud workload management
Use automation solutions when dealing with hybrid or multi-cloud environments to avoid human risks, such as misconfigurations. The complexity of these approaches increases the possibility of human errors, which can ultimately lead to cybersecurity incidents. Minimize human intervention through automation during critical tasks such as infrastructure configuration, monitoring, software updates or patches, and resource provisioning.
You can automate provisioning and enforcing security policies by using IaC (Infrastructure-as-Code) solutions. You can also observe and track the performance of your applications using monitoring and logging tools. This will help you proactively identify and troubleshoot issues as and when they arise.
2. Limit access or privilege to sensitive workloads
Over-privileged access can be a chink in your security shield to be exploited by threat actors. It is often a primary target for attackers who exploit loosely configured privileges to invade your network and breach data. To avoid this, implement strong IAM (Identity and access management) strategies such as RBAC (role-based access control), the zero-trust policy, and reduce privileged access to business-critical data.
3. Centralize your monitoring and tracking efforts
Having comprehensive visibility of the resources you have spread across cloud environments will effectively secure your workloads. Usually, in multi-cloud and hybrid cloud architectures, monitoring is siloed, with every cloud provider offering varying levels of logging options. Blind spots are created when there isn’t a consistent monitoring and tracking policy.
With a centralized monitoring solution, you can have a holistic view of the state of workloads across cloud environments on a single dashboard. This helps you assess application health, identify anomalies, and initiate remediation steps.
Unlike in monolithic applications, endpoint security won’t work with containers. A runtime security tool, instead, will secure containerized workloads distributed across multiple environments and platforms. It can help identify misconfigurations and improper privileges while monitoring the container environment, including networking and file systems.
Pro tip
This Wiz Research team has found that 58% of cloud environments have at least one publicly exposed workload with a cleartext long-term cloud key stored in it. This greatly increases the risk of lateral movement in the VPC and between VPCs.
Wiz is built to provide end-to-end workload protection, including hosts, VMs, containers, and serverless functions. Wiz’s CWPP solution is bolstered by in-house R&D programs for proactive data breach prevention so you don’t just have a tool, but an entire security task force at your disposal.
The Frost & Sullivan survey recognized Wiz saying its "promising product roadmap reflects its commitment to continuous innovation in addressing evolving cloud security challenges.’
At a time when risks to cloud workloads are on the rise, you can experience robust workload protection with CWPP through Wiz. Get a demo here.
