Cloud Endpoint Protection: Protecting Your Weakest Link

In recent years, research has shown that a majority of cyber attacks start by compromising an endpoint, not by breaching an organization’s security perimeter. Many organizations are deploying endpoint security platforms that defend against endpoint attacks using next-generation antivirus (NGAV), endpoint detection and response (EDR), User Behavioral Analytics (UBA) and more.

In the cloud, endpoint protection is even more important. Cloud architectures have a large number of endpoints and require a higher level of visibility. Endpoint protection tools can help organizations regain control over cloud workloads, and protect the weakest link of their security posture.

In this article you will learn:

What Is Cloud Endpoint Security?

In an on-premises data center, endpoint security is used to protect devices like workstations, mobile phones and servers from cyber attacks. In the cloud, endpoints take a different shape—they may machine instances provided by services like Amazon EC2, storage volumes or buckets, or managed services like Amazon RDS.

It may appear that as you move to the cloud, there is less of a need for endpoint security. However, the opposite is the case. As workloads move to the cloud, the number of endpoints grows exponentially, endpoints change more frequently, and there is less central control and visibility. Each cloud endpoint is a potential entry point for attackers, and should be protected with a consistent layer of endpoint protection.

Cloud Endpoint Security Challenges

Private Cloud Endpoint Security

A private cloud is entirely within your organization’s control, and so it may appear that endpoints in a private cloud are inherently more secure. However, private cloud endpoints are still vulnerable to attack:

  • Insider attacks—a malicious employee or compromised account can initiate a cyberattack from within your private cloud. Endpoints are typically connected to other endpoints and control systems via the network, and an attack can spread via lateral movement and privilege escalation to more sensitive resources. A common way to compromise endpoints is spear phishing, where attackers study the behavior of victims inside the organization and send a carefully-crafted, credible email and causes them to click a link and deploy their malicious code.
  • Non-compliance liabilities—organizations need to make sure endpoint controls are properly configured and sensitive data is appropriately protected. If the required controls are not in place, and there is an audit or real breach, your organization may be at risk of losing their certification or being fined.
  • Data leakage—occurs when intellectual property, an organization’s critical data, or safety controls are leaked to an outside source, very frequently via compromise of an unsecured endpoint. Data can be exfiltrated by malware installed on the machine by an attacker, tunnelled over existing communication protocols like DNS, and can also be transferred by a malicious user using cloud storage, FTP, Tor, or other methods.

Lastly, an organization needs to determine how its private cloud security interoperates with other corporate information and workloads away from the personal cloud. If any data is shared or exchanged, as in many hybrid cloud architectures, additional measures need to be implemented, such as integrating endpoint security management with security tools used for the cloud.

Hybrid Cloud Endpoint Security

Hybrid cloud lets organizations manage a private cloud for critical data, while enjoying the scalability and affordability of the public cloud for large-volume storage, additional computing capacity, and dev/test environments. Endpoints deployed either on-premises or in the public cloud in a hybrid model are vulnerable to attack vectors affecting both public and private cloud environments.

Even more significantly, hybrid cloud endpoints are vulnerable to security concerns with the integration points between the on-premises data center and the public cloud. Security concerns include:

  • Lateral movement from public to private cloud—an attacker gains access through the public cloud and performs lateral movement to access and infect private cloud resources. An infected endpoint may also automatically spread malware to other machines it is connected to, which may be on-premises.
  • Compliance and security gaps—in many hybrid cloud environments, you do not have central visibility of all endpoints and cannot easily identify security gaps or missing security controls required by compliance standards.
  • API vulnerabilities—APIs are also endpoints, which can expose sensitive information. Attackers can use an authentication/authorization token to obtain or manipulate sensitive information. Many hybrid cloud setups heavily rely on APIs, and it is a challenge to ensure all API endpoints are properly secured.
  • Integration points—every integration point between clouds, or between systems from different vendors, can be vulnerable to attack.

Public Cloud Endpoint Security

A public cloud is susceptible to attackers that may not be visible to IT and security staff and may not be under their control. Typically, the cloud provider is responsible for security measures of the cloud environment, and cloud users take responsibility for securing their workloads and configuring access in a secure way. Therefore, public cloud deployments are also vulnerable to private cloud and hybrid cloud security challenges outlined above.

Many organizations use multiple computing models, including public Infrastructure as a Service (IaaS) like Amazon EC2, Platform as a Service like Amazon Lambda and Software as a Service (SaaS) such as SalesForce or Microsoft Office 365. Identifying all the endpoints on each of these platforms, understanding the access controls made available by each cloud provider, and ensuring all endpoints are configured correctly, can be a challenge. Without specialized tools, you will not have central visibility and control over all public cloud endpoints, and may have to “hunt” for them and identify security configuration issues one by one.
