ESG Lab Review: ForeScout Extended Module for IBM BigFix

Abstract

This report provides a first look at the key benefits of integrating ForeScout CounterACT with IBM BigFix endpoint management and security solution. ESG Lab focused on how the ForeScout Extended Modules can combine ForeScout’s endpoint insight, classification, and control capabilities with IBM BigFix. This integration is designed to discover and classify users and devices, verify the presence and operation of BigFix Agents, enforce compliance, and take automated host or network actions when needed.

The Challenges

According to ESG research, strengthening cybersecurity was cited by 44% of respondents as the business initiative that would drive the most technology spending at their organizations in 2018 (see Figure 1).1

This is hardly surprising, considering the multitude of cybersecurity incidents organizations are experiencing. In a 2016 research project conducted by ESG and the Information Systems Security Association (ISSA), 39% of cybersecurity professionals said that their organization had experienced one or more incidents resulting in the need to reimage one or more endpoints or servers; 27% reported experiencing a ransomware incident; and 20% stated they had experienced at least one security incident that disrupted a business application.2 Adding to these challenges is an increasing skills gap in cybersecurity. Fifty-one percent of organizations claim that they have a problematic shortage of cybersecurity skills—the most frequently cited response by a wide margin.3 In addition, the increase in mobile, personal, transient, and even virtual devices leaves many organizations unaware of a significant percentage of the endpoints on their networks. These devices are either not under management, have nonfunctional agents, or are only detected during intermittent scans.

The ForeScout Extended Module for IBM BigFix

The ForeScout CounterACT platform is designed to provide continuous security monitoring and remediation of an organization’s devices, both traditional and nontraditional, while they remain connected to the network. ForeScout’s goal is to provide IT organizations with comprehensive insight into their endpoint landscape and compliance posture while addressing network access and threat management challenges.

In conjunction with ForeScout CounterACT, the ForeScout Extended Module for IBM BigFix provides visibility, classification, and exchange of real-time contextual information for managed and unmanaged endpoints. CounterACT verifies whether a BigFix agent is installed and operational on an endpoint, and can enroll the client or restart the agent if needed. BigFix then checks the device’s compliance status and shares it with ForeScout. If the device is non-compliant, ForeScout initiates appropriate isolation and/or remediation actions leveraging CounterACT for network-level device isolation and BigFix for endpoint patch deployment or configuration changes.

The joint solution utilizes ForeScout’s agentless discovery and control of endpoints on the network, enabling real-time endpoint visibility and profiling of traditional and non-traditional devices that are not managed by BigFix, including network infrastructure, operational technology (OT) systems, BYOD, IoT devices, phones, and tablets. The ForeScout Extended Module for IBM BigFix allows organizations to identify corporate endpoints that are missing and that need the BigFix Agent and to automatically deploy BixFix Agents to those endpoints. In addition, when BigFix sends messages indicating compliance violations, ForeScout triggers automated network actions to isolate and/or remediate endpoints. ForeScout also interfaces with BigFix to verify and enforce an endpoint’s compliance state with security and regulatory mandates, and facilitates automated host actions to remediate endpoints.

ESG Lab Tested

ESG Lab evaluated the ForeScout Extended Module for IBM BigFix which creates a bi-directional integration between ForeScout CounterACT and IBM BigFix. ESG validated the ability of the joint solution to discover and profile endpoints as they attach to the network, verify whether the BigFix agent is installed and running, and verify compliance.

ESG Lab configured the integration between ForeScout CounterACT and IBM BigFix in just a few steps. First, ESG Lab created an account on the BigFix root server for ForeScout, and then configured the ForeScout Extended Module for IBM BigFix with the IP address of the root server and the login credentials. The whole process took less than a minute, and we used the built-in CounterACT policies for BigFix. Once the integration was configured and endpoints connected to the network, we could see the information collected by the ForeScout Extended Module (Figure 3).

ESG demonstrated that the ForeScout platform can discover and profile traditional endpoints that can be managed by IBM BigFix, such as the Windows machine shown above, as well as non-traditional endpoints that are not managed by BigFix like network infrastructure devices, BYOD endpoints, and IoT devices. In our tests, ForeScout provided extended visibility and control across device types when they connected to the corporate network. BigFix provided endpoint configuration management and security regardless of corporate network connectivity and bandwidth. ForeScout visibility provided for the discovery of corporate devices that should be protected with configuration management through BigFix. The ForeScout Extended Module for BigFix also leveraged BigFix properties for applicable endpoints, which enhanced real-time insight, enabled refinement of policies and enforcement with automated controls through CounterACT. As seen in Figure 4, the ForeScout Extended Module verified endpoint OS and patch level compliance. Configuration hardening and other configuration requirements can also be verified and enforced for required enpoints.

Compliance violations can be addressed and resolved with a combination of actions by CounterACT (isolation/quarantine) and BigFix (endpoint patch/configuration change).

The Bigger Truth

The unprecedented diversity of users, devices, and applications on networks—where employees, contractors, guests, and partners often use personal devices to connect to network resources—challenges businesses to efficiently provide them all with appropriate network access.

IBM BigFix delivers multiple management services for corporate managed systems, including real-time device status reporting, patch and software distribution, security policy enforcement, and response and remediation. IBM BigFix is an agent-based solution with a server and console component that provides a real-time view of device status. The BigFix server provides both a control center and a repository for managed system configuration data, software updates and patches, and other configuration and management information.

ESG Lab was quite impressed with ForeScout CounterACT’s ability to empower organizations using IBM BigFix to efficiently provide visibility and control of endpoints accessing the corporate network, both internally and from the internet, to boost endpoint compliance, reduce risk, and improve network protection.

ForeScout CounterACT demonstrated that it can provide visibility, intelligence, and policy-based mitigation of security issues by providing real-time agentless discovery of managed and unmanaged devices while coordinating security controls and automating responses with IBM BigFix. If your organization is currently using or considering IBM BigFix for configuration management, it would be worth your time to look at how ForeScout CounterACT can work with IBM BigFix to improve visibility, increase endpoint compliance, and reduce vulnerabilities in devices both on- and off-premises, all while reducing management complexity.
