General Product Questions
The Heartbleed Bug (CVE-2014-0160) is a recently published vulnerability in the OpenSSL cryptographic software library, which if exploited in its fullest extent would enable an attacker to eavesdrop and take data from an SSL/TLS encrypted communication session. Specifically, it can in some cases result in the attacker obtaining sensitive data, such as encryption keys and service credentials.
Only one component within CounterACT implements SSL sessions using a vulnerable version of the OpenSSL library — specifically CounterACT SecureConnector for Windows®, and only when running specific Hotfixes on ForeScout CounterACT 6.3.4x and 7.0.
ForeScout CounterACT Hotfixes that address this limited exposure are readily available to customers and partners via our customer portal. The ForeScout security advisory link 14-01 has more details and is located at:

Gartner, Inc. evaluated the NAC market in December 2013 and predicted* that the market would grow approximately 45% in 2014. The overall growth for Network Access Control adoption is being fueled by five trends:
- The demand for a wide range of personally owned devices to gain access to the network while preserving security.
- The failure of traditional security software to assure endpoint compliance and stop zero-day, targeted (APT) and propagating threats such as Conficker and Zeus.
- Maturing compliance mandates, both internal and external (government regulation), that require controls for all access to, and protection of, sensitive data and personally identifiable information (PII)
- The explosion of “consumer” devices accessing corporate networks, e.g. iPhones, iPads, Androids, and personal laptop computers.
- The use of social media, unsanctioned personal data sharing, malware and phishing techniques for social engineering purposes to gain a foothold in endpoint devices
* Gartner, Inc., “Magic Quadrant for Network Access Control”, Lawrence Orans, December 2013.
NAC was originally designed for a world that does not exist today—a world of Windows hegemony, with PCs connected to wired LANs, operated mostly by employees, and updated (patched) periodically. In this environment, NAC would function like a security agent on an airport security line—denying access to the network unless the user and the device could prove their identity and compliance with security requirements.
The modern enterprise IT environment is now radically different, characterized by:
- Widespread acceptance of end-user mobility and BYOD policies
- A transition from periodic monitoring and patching to continuous monitoring and remediation
- A pressing need for security operations automation, for both speed and efficiency
- A drive toward “contextual security” policies and enforcement
In response to this new IT environment, NAC products are evolving to a much broader functionality characterized by the following:
- Greater endpoint visibility and coverage. This especially includes the ability to detect, categorize and inspect non-Windows devices such as smartphones and tablets, personally owned computing devices which lack endpoint security agents, industrial equipment, and virtualization.
- Continuous monitoring of endpoint configuration and status to support evolving governance and compliance needs
- Integration with other IT security and management systems such as SIEM, firewall, VPN, identity management, vulnerability scanning, trouble ticketing, MDM, advanced threat detection systems, etc.
Some market researchers (for example, Enterprise Strategy Group) are suggesting that the evolution is so significant that a new name should be used for this product category, such as EVAS—”Enterprise Visibility, Access and Security”.
Our company’s growth is fueled by the strength and versatility of the ForeScout CounterACT platform. This boils down to five things:
- Easy and non-disruptive. ForeScout CounterACT is dramatically easier and faster to deploy than traditional NAC products. One box, one day to install. Everything is built into the appliance. No software to install. No changes to your existing infrastructure. By supporting both 802.1X and non-802.1X, trusted access and endpoint compliance can be assured with the least impact to your end users and operations.
- Integrated. ForeScout CounterACT includes a large range of functionality: An extensive range of automated controls that let you manage your network the way you want to. Full-featured guest registration. Visibility and network access control of all the most popular smartphones. Extensive information about everything on your network – devices, users, applications, ports, peripherals, etc. Built-in options for remediation that include updating security agents, patching operating systems, even killing unauthorized applications and processes.
- Scalability. ForeScout CounterACT scales better than anything on the market. We have customers today with over 750,000 endpoints, all being managed by a single ForeScout CounterACT Enterprise Manager console.
- Manageability. ForeScout CounterACT is easy to manage. Our engineers have a passion for developing good user interfaces and setup wizards. People who test our product and compare it to competitors’ products consistently tell us that ForeScout CounterACT’s user interface is easier and more intuitive than competitors’ products.
- Interoperability. ForeScout CounterACT works with your existing infrastructure. The approach is completely vendor agnostic. For example, switches, directory services, anti-virus software and other network and security infrastructure from almost any vendor can be used and networks with multiple vendors are easily supported.
ForeScout CounterACT is delivered in either physical or virtual appliance form.
ForeScout CounterACT is licensed by the number of network devices (IP addresses) that are within the scope of the appliance.
- Each of our physical appliances is built to handle a certain number of network devices, and each appliance comes with a license for that number of devices. Our range of licenses ranges from 100 devices (CT-R appliance) to 10000 devices (CT-10000 appliance). In between, we have appliances that are licensed for 500 devices, 1000 devices, 2500, and 4000 devices.
- ForeScout CounterACT Virtual Appliance is licensed the same way as our physical appliance. We offer licenses for 100, 500, 1000, 2500, 4000 and 10,000 devices.
ForeScout also offers a ForeScout CounterACT Enterprise Manager to streamline management of up to 200 ForeScout CounterACT appliances. Licensed by the number of ForeScout CounterACT appliances under management, ForeScout CounterACT Enterprise Manager enables customers to centrally see and manage all endpoints, policies and appliances. We also offer high-availability pricing for our physical appliances. Our HA pricing includes a license for a set number of users plus two appliances covered within the scope of that license.
ForeScout Mobile Security Module is a plugin that works with ForeScout CounterACT. The plugin is downloaded from ForeScout’s customer support web site and installed in the ForeScout CounterACT appliance (if the customer is just using one ForeScout CounterACT appliance) or the ForeScout CounterACT Enterprise Manager appliance (if the customer is using multiple ForeScout CounterACT appliances).
ForeScout Mobile Security Module is licensed according to a specified number of mobile devices. A single ForeScout Mobile Security Module license is applied to a ForeScout CounterACT appliance or, if multiple ForeScout CounterACT appliances are in use, to a ForeScout CounterACT Enterprise Manager. For example, suppose you have one ForeScout CounterACT CT-R, one ForeScout CounterACT CT1000, and one ForeScout CounterACT CT-4000 appliance. In this situation, you have licenses to operate ForeScout CounterACT for a total of 5100 IP addresses. If you wish to obtain additional visibility and control over 100 mobile devices, you would purchase one ForeScout Mobile Security Module license for 100 mobile devices.
Multiple ForeScout Mobile Security Module licenses may be purchased in order to achieve a larger license. For example, if you purchase two copies of the ForeScout Mobile Security Module for 100 mobile devices, we will send you a license key for 200 mobile devices.

Network Access Control Functionality
“When it comes to network access control (NAC), ForeScout CounterACT is the most superior solution on the market. Don’t just take our word for it, get a 24-page, comprehensive comparative report on the leading NAC products produced by The Tolly Group.”
ForeScout CounterACT has built-in support for the following methods to control network access:
- 802.1X: VLAN steering or switch blocking
- Switch blocking using SNMP
- VLAN Steering
- ACL enforcement
- Virtual Firewall
- Built-in RADIUS server, plus the ability to function as a RADIUS proxy. The proxy mode is useful if you are already using a RADIUS server and don’t wish to utilize the RADIUS that is built into CounterACT.
- Built-in visibility tools to help you see whether your switches and endpoints are all correctly configured for 802.1X authentication. The tools can be run in monitor mode before you start to enforce 802.1X access control; this lets you solve problems before they become disruptive.
- Built-in remediation tools identify when an endpoint does not have a properly configured supplicant. When such an endpoint is found, CounterACT can run a script to install and/or configure the supplicant.
- Hybrid NAC includes the ability to utilize 802.1X or other authentication technologies within the same network. This has two benefits: 1) It lets you roll out NAC quickly and completely in an environment that does not support 802.1X in every location. 2) It provides a redundant authentication mechanism for endpoints that fail the 802.1X authentication for whatever reason.
- Support for a wide variety of vendors’ switches and wireless access points: is configured to function as a RADIUS proxy. In this model, ForeScout CounterACT becomes the authentication server for the switch and the authenticator for the RADIUS server. ForeScout CounterACT provides integration with 802.1x switches and supports 802.1x switches from Cisco, Extreme, FoundryBrocade, Nortel, Aruba, and HP ProCurve.
- Support for a wideForeScout CounterACT variety of network enforcement methods: 1) VLAN assignment, 2) ACL management, 3) virtual firewall. This flexibility allows customers to quickly deploy our NAC solution in difficult network environments, e.g. when computers are daisy-chained to VoIP phones.
- Automated MAC exception lists based on ForeScout CounterACT’s built-in endpoint profiler. CounterACT automatically identifies endpoints that do not support 802.1X supplicants—for example, printers—and will place these endpoints on the network and then add their MAC addresses to an exception list. CounterACT continuously maintains the exception list and monitors every endpoint in order to prevent MAC address spoofing. places authenticated endpoints into the proper VLAN according to the end-user’s role and as determined by LDAP grouping. ForeScout CounterACT places non-compliant or unverified endpoints in a remediation VLAN or in a lobby VLAN for inspection. The exact behavior is configurable by our customers.
802.1X is just one type of authentication protocol that ForeScout CounterACT supports, the others being authentication against an LDAP directory such as Active Directory, authentication against CounterACT’s built-in guest registration database, and authentication against CounterACT’s built-in MAC address bypass list. It is up to the customer to choose which authentication protocol he wishes to use.
In general, 802.1X is a very secure method of device authentication, but there are alternative approaches that are just as secure. As IT environments become larger with more heterogeneous equipment and a large number of legacy devices which do not support 802.1X, the overhead of deploying 802.1X, managing the exception list, and deploying and remediating 802.1X supplicants may become burdensome. In these situation, alternative authentication approaches should be considered.
Spire Security has written an excellent description of the pros and cons of 802.1X. For more details, see “Network Access Control and 802.1X: Advantages, Constraints and Capabilities” by Spire Security.
Also watch this video which shows how ForeScout CounterACT provides strong port control with or without 802.1X and how CounterACT enhances 802.1X so that it is truly enterprise-ready.
The 802.1X protocol is inherently ungraceful in the way that it handles new endpoints that lack supplicants, such as printers. This is one of the drawbacks to 802.1X and why many ForeScout customers do not utilize 802.1X.
The only one way to allow new devices without supplicants (such as printers) onto an 802.1X network is to enter the MAC address of the device into an exception list which is stored on the RADIUS server. This can be done prior to putting the device onto the network, or afterwards. If afterwards, you can configure a policy within ForeScout CounterACT that automatically handles the onboarding of endpoints such as printers without supplicants, as well as more capable endpoints (computers, smartphones, etc.) that have not yet been configured for 802.1X. Using ForeScout CounterACT’s hybrid NAC, any device that fails 802.1X authentication is placed in a lobby VLAN. If the device is a printer or other piece of equipment, ForeScout CounterACT can be configured to automatically add that device’s MAC address to an exception list, then CounterACT can move that device to the production network. If the device is a computer, ForeScout CounterACT can be configured to give the user an opportunity to authenticate via another method, such as by entering his Active Directory credentials. If the user is a guest, ForeScout CounterACT can give the user the opportunity to register for guest access on the network. As the number of unmanaged (BYOD) computers that need to access corporate networks increases, ForeScout CounterACT’s hybrid NAC becomes an increasingly attractive solution to any organization that wants to maintain high end-user productivity and minimize the number of help desk calls.
No. Many NAC solutions rely on DHCP blocking as an alternative to 802.1X enforcement. Unfortunately, DHCP enforcement is an inherently ineffective enforcement option because it is easily bypassed, will not work in certain environments, and is unrealistic for enterprise NAC deployments. Even if successfully implemented, it still lacks the ability to provide point of access control through VLAN steering or port up/port down.
Some of the fundamental issues with DHCP enforcement include:
- DHCP enforcement is “opt in” enforcement because it relies on the end-user to obey specific rules.
- DHCP blocking will not work on users that connect to the network with static IP addresses.
- DHCP blocking is effective only when the end-point requests/renews its DHCP lease. Once DHCP hands out an address, there is no way to take it back. If someone becomes infected or policy needs to block a user after connect, there is no way to take back the IP address until the DHCP lease expires.
In the case of ForeScout we just use the DHCP as a form of discovery to detect a new admission
ForeScout CounterACT can assign an endpoint to an appropriate VLAN based on the policy that you configure within the ForeScout CounterACT policy manager. The actual port assignment can be done via 802.1X or via SNMP. The latter option is plug-and-play, does not require 802.1X, requires no software on the endpoint, and is able to manage any device on the network including guests and non-OS appliances.
ForeScout CounterACT provides the ability to dynamically update ACL’s on firewalls, routers, and switches. This lets you enforce security policies at a very granular level, leveraging your existing switch infrastructure. Beyond just restricting a device to a specific VLAN, ACL-based enforcement can restrict access on a device-by-device basis or port-by-port basis. ACL management lets you apply different policies in situations where multiple devices are connected to a single switch port, for example when workstations are connected to VoIP phones, or when multiple virtual machines are connected to a single switch port. While some NAC solutions provide basic ACL management capabilities, competitors typically limit their support to L3 switches or routers at the core of your network. ForeScout’s ACL management works at the access layer and gives you tremendous enforcement granularity with no administrative overhead.
ForeScout CounterACT’s virtual firewall uses surgical packet injection to offer granular and dynamic control of traffic. Essentially, it is a TCP reset mechanism. Unlike competitors’ TCP reset mechanisms, which send the RESET to the source after the data is already on the wire, ForeScout CounterACT will send the RESET to the destination after the first SYN, tearing down the connection before the handshake completes. This can be done as often as necessary to isolate a device from specific or all network resources. In addition, ForeScout CounterACT tears down UDP sessions by sending ICMP unreachable messages to both client and server. This method is effective in query-response protocols, such as DNS. This system is a very easy and flexible way of providing role-based access, even separating traffic that is on the same VLAN. It can also be used to provide NAC functionality where VLANs are not possible (e.g. flat networks) or where proper role-based access would require too many VLANs (separating employee roles on the same network.)
What does an end-user experience when ForeScout CounterACT starts to enforce network access control policies?
Enterprise end-users whose credentials are present in the enterprise authentication system will generally not notice anything different–their PCs will be automatically joined to the network. However, users that are non-compliant will see either automatic or guided mediation efforts. These will begin with notification via email, http, or balloon messages.
Your policy on how to handle guest users can be customized to meet the needs of your organization. Most people configure ForeScout CounterACT so it will prompt guests to enter a network password, or to register for a password if they have never before joined the network.
Yes. ForeScout CounterACT provides a built-in policy to identify and distinguish guest users from corporate users. The most critical part of any guest networking application is the ability to determine whether a connecting device is a “guest”. Because organizations have various standards for what constitutes a guest device, ForeScout CounterACT provides several options to identify guest vs. corporate devices. These include — but are not limited to — the following:
- Device authentication vs. Active Directory
- Check for presence of SecureConnector installed on the device
- Check to see if the device is not part of domain or if admin credentials fail
- Check to see if the device is on an “approved device list”
- Check to see if the NetBIOS hostname matches corporate standard
- Query an endpoint for buried registry settings or a specific file
- Any combination of the above
Yes. ForeScout CounterACT can manage users and enforce their network access based on the role of the logged-in uer. User management can be done internally or via integration with any of the common identity management systems.
ForeScout CounterACT works with Microsoft AD, Novell directory, Sun, Lotus Notes, RADIUS, TACCAS, and any user-defined LDAP server.
ForeScout CounterACT supports Nortel and Juniper SSL VPN gateways and Cisco, Nortel and Juniper IPsec VPN gateways. ForeScout CounterACT provides the ability to conduct complete compliance checks on connecting endpoints (post-connection to VPN gateway). The device is automatically checked for any malicious threat and, if found, the connection is terminated – with temporary revocation of the user’s credentials. ForeScout CounterACT can notify the end user prior to disconnecting their device. Enforcement is completely configurable and can be set for a specific timeframe (e.g., User “janedoe” will not be allowed to logon for 1 hour).
ForeScout CounterACT keeps track of traffic from all network devices. Rogue devices show up as new network devices that do not conform to policies. For example, they show up as NAT devices, or as devices from an unapproved vendor.
ForeScout CounterACT uses both passive monitoring and active scanning to detect all devices on the network, as long as the device has an IP address or is connected to a device with an IP address. The only devices that ForeScout CounterACT cannot detect are completely passive devices like an Ethernet line tap. For more details, see our whitepaper “Device Host and Detection Methods“.
Yes, ForeScout allows enterprises to quickly enable a bring-your-own-PC to work policy. Without agents or through a non-persistent agent, ForeScout CounterACT can identify, assess the security posture and apply a variety of controls for any device connecting to the network. In particular, systems that do not have particular security services invoked can be re-directed to a self-remediation center or ForeScout CounterACT can attempt to remediate the endpoint with little to no IT intervention. See a presentation on how ForeScout enables and safeguards BYOPC – IT Consumerization. Learn how the City of Guelph advanced their BYOPC policy using ForeScout CounterACT.
ForeScout CounterACT operates as an out-of-band network security appliance (physical or virtual appliance). The appliance connects to a core, distribution or access-layer switch via span port, mirror port or via traffic aggregator. An out-of-band Network Access Control appliance has the following advantages over in-line approaches:
- Seamless deployment: does not require any architectural changes or down time.
- Does not impact network performance.
- Can not be a single point of failure
- Fails-on; does not affect operations should the system be unavailable.
- Flexible deployment: broad infrastructure support.
CounterACT provides customers with a wide variety of deployment options depending on their needs, the level of network access and endpoint compliance control, as well as the operating environment. The appliance connects to a core, distribution or access-layer switch via span port, mirror port or via traffic aggregator ForeScout recommends CounterACT to be at the distribution or core layer switches but this approach will vary depending on each customer’s specific needs and network architecture. In some cases, the CounterACT appliance doesn’t even have to be on the same network as the endpoints being monitored such as those customers that have remote sites.
ForeScout CounterACT RemoteControl is a new feature included within CounterACT that allows IT managers to monitor the compliance of endpoints while they’re off the enterprise network. The CounterACT RemoteControl appliance is placed in a corporate DMZ and communicates with remote hosts via the ForeScout SecureConnector. SecureConnector is a lightweight agent that creates a secure connection with the RemoteControl appliance and enables internet-based compliance management. This eliminates the need for “punching holes” in your corporate firewall and allows the CounterACT RemoteControl appliance to:
- Profile the remote device
- Gather software and hardware inventory information
- Assess the security posture of the endpoint
- Apply corporate security policies
- Take actions to facilitate remediation of endpoint security deficiencies
Both the CounterACT RemoteControl and on-network CounterACT appliances are administered through the CounterACT Enterprise Manager, enabling unified policy management, security posture assessment and compliance views for both on-site and remote devices.
* ForeScout CounterACT RemoteControl planned availability – mid-2014
ForeScout CounterACT can be deployed with or without an agent on the desktop. Both options provide 100% full functionality.
The name of our agent is ForeScout SecureConnector. SecureConnector can be installed in either dissolvable or permanent (persistent) mode. Once installed, SecureConnector creates an SSL-encrypted VPN-like tunnel back to the ForeScout CounterACT appliance. SecureConnector supports Windows (2000, XP, 2003, Vista, Window 7), Mac and Linux/Unix devices.
Regardless of whether you use our agent, the ForeScout CounterACT appliance performs the endpoint interrogation, remediation and enforcement. This includes patch levels, anti-virus status, registry settings, services/processes, firewall configuration, file versions, application compliance, termination of specific processes, USB enforcement, log-off, and shutdown of customer-defined scripts. It is important to note that the trust and logic of policy enforcement is maintained by the ForeScout CounterACT appliance rather than via the endpoint agent. This is a security benefit, because malware will often attempt to spoof or disable the security agents that are resident on the host.
ForeScout CounterACT can obtain some information about endpoint devices through passive listening and interrogation of the switch infrastructure. In order to obtain detailed information about endpoints devices, ForeScout CounterACT conducts a remote login to the device. Once logged in, ForeScout CounterACT can inspect virtually any criteria, including registry settings, and active/inactive processes. ForeScout also offers a lightweight agent called SecureConnector which is helpful for :
- Killing or controlling USB ports
- More frequent killing of a process (up to once each second, instead of once each minute without SecureConnector)
- Balloon messages
- VoIP environments present/missing applications. This covers standard NAC criteria (AV, patch level, IM, etc.)
Does ForeScout CounterACT detect the existence of malware on an endpoint or propagation of malware on your network?
Yes, using multiple methods:
- Detecting attacks on the network, using ForeScout’s patented ActiveResponse technology.
- Detecting unexpected behavior, such as when a printer starts acting like a Windows host.
- Detecting effects of malware, e.g. when antivirus is repeatedly disabled on a system
- Unauthorized configuration changes or drifts, e.g. change to registry settings
For example, ForeScout ActiveResponse was able to detect and block attacks such as Zeus, Stuxnet and the recent FLAME zero day attacks on day-zero – before any security company anywhere had developed a signature for these attacks. The technology has been able to detect and block tens of thousands of worms, such as the infamous Conficker. Armed with ActiveResponse™ companies can reduce the risk of APTs in two ways. First, it blocks APTs that attempt to spread over the network, such as FLAME did. Second, it can thwart the ability of APTs to locate and steal information over the network by identifying behavior as was in the case of Operation Aurora.
Yes. The U.S. Department of Homeland Security now requires all U.S. Federal agencies to continuously monitor IT infrastructure to eliminate intrusions (confidentiality), protect sensitive information (integrity), and mitigate exposure to denial of service cyber-attacks (availability). ForeScout CounterACT addresses Federal requirements. CounterACT uses a combination of discovery techniques to accurately classify and inspect endpoints. CounterACT’s agentless solution enables it to work with all types of endpoints–managed and unmanaged, known and unknown. For more information, see our solution brief note titled “Addressing Continuous Diagnostics & Mitigation (CDM) Requirements with ForeScout CounterACT”.
Yes. ForeScout CounterACT offers fully automatic remediation. In addition, it can integrate with third-party patch management systems (such as Microsoft SMS/SCCM, WSUS, etc.). ForeScout CounterACT provides complete automated remediation using clientless or agent-based methods. This includes patch management, antivirus updating, registry and configuration management, application and service control, file version management, as well as a completely scriptable configuration and installation system.
Yes. ForeScout CounterACT offers Web-based interactive user dialogs with automated or self-guided remediation.
The ForeScout CounterACT system communicates with the user with personalized, customizable web pages. Because ForeScout CounterACT can open these web pages automatically (without waiting for the user to browse the web) the user is immediately informed. The web interface can direct the user to resolve the problem with detailed instructions, web links or contact phone numbers, or merely inform the user of the remediation that is being done automatically by the appliance.
Does the ForeScout CounterACT agent pass parameters (e.g., missing patch) to a remediation agent, or does it simply “kick off” the remediation agent?
Both are possible. When remediating the endpoint using its own clientless or agent-based method, the ForeScout CounterACT system passes on specific parameters (i.e. configuration, registry value, etc.). When leveraging a third-party agent, ForeScout CounterACT will cue the update agent then monitor for completion of the remediation process.
Yes: ForeScout CounterACT integrates with Remedy and can send alerts to most any trouble ticketing system using industry-standard protocols (SYSLOG, SNMP, SMTP).
ForeScout CounterACT is fully integrated with Microsoft SMS/SCCM and can trigger remediation by that system. If an endpoint is found to be out-of-compliance due to out-of-date antivirus, ForeScout CounterACT can trigger an AV update. Most importantly, ForeScout CounterACT includes a scripting engine that integrates with virtually any remediation product. In short, a customized script can be written to cue any patch process based on policy results: for Mac/Linux, this will be a shell script; for Windows this will be a C-script; we also support standard console scripts that will initiate .bat and .exe files.
Yes – based upon ForeScout’s patented technology. ForeScout CounterACT can instantly identify both human and self- propagating threats without requiring signatures or anomaly detection.
Following the patented ActiveResponse ™ methodology, the appliance uses specially-crafted information to respond to network reconnaissance and access attempts. If a device takes this information and attempts to use it to gain access to the resource, ForeScout CounterACT determines this to be a malicious threat. Based upon enforcement policy in place, the device will be isolated, quarantined or blocked.
Yes, ForeScout CounterACT allows you to define a change tracking policy. This feature allows the administrator to take automatic action when a specific property of an end-point changes (for example, if an end-point profile changes from “Printer” to “windows”).
