Growing From Vulnerability Management to Cyber Exposure

Managing Cyber Risk in a Dynamic, Cloud-native Infrastructure Requires More Than Legacy Vulnerability Management Tools

Netskope is a cloud access security broker (CASB) vendor whose patented Cloud XD technology gives clients 360-degree visibility into the cloud with data protection.

To manage the company’s cloud-native infrastructure, the Netskope team wanted to evolve its cybersecurity risk management from legacy vulnerability management to a more strategic approach for Cyber Exposure.

Netskope wanted more inclusive and holistic cyber risk management strategies, which revealed there was a gap between what the company wanted to accomplish and existing vulnerability management tools.

The team’s goal was to move from vulnerability overload—data with no context and no insight to quickly prioritize risk and response—to a more effective way to manage cyber risk decisions.

For this transition, Netskope deployed Tenable for continuous visibility into its Cyber Exposure. With Tenable’s advanced reporting, the company can now align its security goals to business objectives.

Frequently Asked Questions About Cloud Security

Do you have questions about cloud security? Here are some frequently asked questions and answers:

What is cloud security?
Cloud security is made up of processes, tools, resources and policies to protect all of your data and resources stored off-premises and in the cloud. It continually assesses all of the assets within your cloud environments so you can discover and remediate vulnerabilities, misconfigurations and other security issues to keep your organization safe.
What security risks exist for cloud computing?
While cloud computing brings a lot of flexibility and scalability to your organization, there are a number of security risks. Any time you move your data and workloads off on-premises, you lose some control. For example, Amazon Web Services (AWS) has a shared responsibility model that means AWS is responsible for physical security of the cloud, but you are responsible for your data and workloads. Also, most cloud providers aggregate data and services into their systems, meaning attackers can often access more data with less work. That means cloud environments can increase the value of a hacking target. Other potential risks include blind spots in your cloud environment, not meeting legal requirements or compliance obligations, losing service if your cloud provider goes down or you lose connectivity to your cloud, unauthorized access to your data by your cloud provider’s employees, or the potential your data stored in the cloud and could be lost.
Why is cloud security important?
Cloud security ensures your data, business workloads, and apps remain safe while they are stored off-site within a cloud infrastructure. While most cloud providers have a much higher level of security than many on-premises solutions, continuous discovery and assessment of your cloud assets will help you further protect your information stored in the cloud. Whether you’re a business facilitating workloads or you’re an individual who needs extra storage for your files, cloud security can help ensure all of your data remains secure.
What are cloud attacks?
The cloud is a potential attack vector hackers can use to exploit vulnerabilities and put your organization at risk. There are a number of ways attackers can attempt to exploit your cloud environments. For example, an attacker can inject malware to access information stored in the cloud and once inside move laterally to affect other systems. Other types of cloud attacks can include Denial of Service (DoS) or brute force attacks, wrapping attacks, service hijacking, man-in-the-middle attacks, insider attacks, and side-channel attacks.

Aligning Cloud Security With Your Cyber Exposure Lifecycle

Cloud solutions are all about speed, scale and usability.

While cloud infrastructure brings many benefits and flexibility to your organization, it can also increase your cyber risk. From asset discovery to benchmarking success, your cloud security processes should correlate with the five phases of the Cyber Exposure lifecycle:

  1. Discover

    If your organization has moved processes and applications to the cloud, then you likely know it’s built for speed and you can easily scale with it. And while that’s great for business efficiencies, it can create new challenges for your security team by inadvertently increasing your cyber risks.

    Tenable’s Cloud Connectors for Amazon Web Service (AWS), Google Cloud Platform (GCP) and Microsoft Azure enable detection of new short-lived compute asset deployments across cloud environments. That means you can keep up with cloud-native assets like auto-scaling, on-demand instances and container deployments.

  2. Assess

    If you’re using legacy vulnerability management scanning tools for your cloud environments, you may have blind spots within your attack surface.

    Instead of those legacy tools, harden your cloud infrastructure based on Center for Internet Security (CIS) best practices.

    From host to workloads and data, Tenable can help you find vulnerabilities, misconfigurations, and other security issues across all your cloud assets so you can plan and prioritize for remediation.

  3. Prioritize

    Once you’ve assessed all of the assets across your cloud environments, you need to prioritize which vulnerabilities pose the greatest threat to your organization.

    Tenable enables you to automatically analyze those risks by evaluating threat intelligence, exploit availability and other vulnerability data so you can prioritize remediation for those most likely to impact your organization in the near future.

    Then you can use custom dashboards within Tenable.io to share that information with your DevOps team, and you can automatically send information to your Security Information and Event Management (SIEM) with event context.

  4. Remediate

    Once you’ve discovered all of the assets within your IT attack surface—including your cloud infrastructure and discovered your vulnerabilities, misconfigurations and other security issues–you’ll need to prioritize them for risk so you can quickly and efficiently remediate issues.

    Tenable enables you to shift left with your cloud security so you can find vulnerabilities before they reach production. You can create secure machine and container images before deployment to prevent additional vulnerabilities and you can integrate your vulnerability management processes into your CI/CD systems.

    Additionally, bug-tracking and remediation tools that use APIs enable you to track bugs and seamlessly integrate remediation into your DevOps.

  5. Measure

    Finally, all of these steps align to determine your organization’s complete Cyber Exposure.

    You can use Tenable’s advanced analytics and scoring to get a clearer picture of your actual organizational risk. From there, you can communicate your cloud security program success and weaknesses to your key stakeholders and team members so you can plan for program growth and improvements.

    Internal benchmarking will help you analyze how your program measures up across departments and industry peer benchmarking helps you evaluate your processes against similar organizations.

    From here, you can align your security program goals with your organizational goals to facilitate stronger decision-making and planning for your organization.

Protect Your Cloud Environments With a Risk-Based Approach to Vulnerability Management

Legacy Vulnerability Management Tools Can’t Meet All Your Cloud Needs

Cloud environments enable your business to quickly build and scale new infrastructure and rapidly react to customer demands. But without the right capabilities in place to detect and manage vulnerabilities and misconfigurations in an ever-changing environment, this speed and scalability can be a double-edged sword.

Legacy vulnerability management can’t keep pace with this new paradigm, and point solutions lead to information silos without a unified view of all vulnerabilities.

Your security teams need to adopt a risk-based vulnerability management approach to find all vulnerabilities across your attack surface so you can focus on the critical security issues that matter most—vulnerabilities that are the most likely to be exploited.

Here’s a quick summary of how you can adopt a risk-based approach for cloud vulnerability management:

  1. Discover

    Identify cloud assets in a dynamic environment

  2. Assess

    Use scan templates and deployment models built for cloud providers and cloud-native infrastructure

  3. Prioritize

    Plan and execute vulnerability remediation based on business risk, using machine learning to correlate vulnerability severity, probability of exploitation and asset criticality

  4. Remediate

    From development to operations, prioritize which exposures to fix first, and leverage powerful integrations to optimize your entire vulnerability management lifecycle

  5. Measure

    Measure and benchmark Cyber Exposure to make better business and technology decisions
