General
Q: What is CyberGatekeeper Server?
A: CyberGatekeeper Server is a network access control appliance
for LAN and remote access. It screens LAN, wireless LAN, and remote
access endpoints before allowing access to the network. CyberGatekeeper's
extensive tests ensure existing endpoint security solutions such
as anti-virus software, personal firewalls, operating system patches,
and other software are properly configured and up to date. Guests
can be validated, and rogues are isolated from the network. Unsafe
systems are quarantined until remediated.
Q: What are the benefits of CyberGatekeeper
Server?
A: CyberGatekeeper Server helps an organization in a number of ways:
- Prevents worms, Trojans and viruses from infecting the network.
- Secures LAN, WLANs, and remote access points, and all types
of users including employees and guests.
- Works with existing network infrastructure to eliminate costly
upgrades, and allows the organization to implement needed security
today.
- Scales easily with central management, reporting, and policy
distribution.
- Extensive and flexible remediation options let administrators
control how much user involvement is required and bring systems
quickly into compliance.
Q. What are the key functions
of CyberGatekeeper?
A: Allow access only for endopints meeting key requirements, before
and after admission to the network. These requirements are any combination
of the following: Authenticate, Assess (scan and monitoring), Quarantine
(isolate), and Remediate (resolve and update).
Q. What is the CyberGatekeeper
relationship in regard to other endpoint solutions?
A: CyberGatekeeper collaborates and integrates with all existing
endpoint security such as anti-virus, personal firewalls, patch
management, spyware, and intrusion detection/prevention systems,
by knowing when one of these solutions needs updating. As soon as
an endpoint is deemed non-compliant, that system is immediately
quarantined and blocked from further network access, and network
administrators are alerted. No updates to existing software or security
solutions are required for this integration to occur.
Technical: Network Architecture
Q: What are the main functional
components of the CyberGatekeeper system?
A: There are three main components:
- CyberGatekeeper Server: Hardware appliance used to conduct
audits of endpoint systems.
- Client: Installed or web based agent that runs on the endpoint
systems.
- Policy Manager: Creates and deploys policies.
Q: How does the user desktop
audit process work?
A: The agent is configured with specific conditions that tell it
when to audit. For example, the agent can be configured to audit
when it is on the corporate LAN.
When the agent detects that it should initiate an audit session,
it contacts the CyberGatekeeper address. CyberGatekeeper then sends
the agent a "grocery list" of items to check on the endpoint
system, based on required policies. This list can contain things
such as running processes/modules, registry settings; files attributes
and configuration file settings.
The agent collects the information on the list, and sends the results
back to CyberGatekeeper to compare with the policy. CyberGatekeeper
determines whether the endpoint system is in or out of compliance
and manages access accordingly. CyberGatekeeper may display an optional
message or send a remediation action to bring them into compliance.
Q. Does CyberGatekeeper require
other hardware/software products?
A: No, the CyberGatekeeper solution works with the existing network
environment and all third-party software products. Moreover, a CyberGatekeeper
Agent has the ability to audit and inspect core features of the
endpoint PC. No specific 3rd party application integration is required.
Q: What network resources
are required to provide end-user remediation?
A: A web server to host the remediation files is recommended. For
example, if you provide a patch as part of an auto-remediation solution,
that patch must be hosted on a web server that is accessible when
the user has failed an audit.
Q: What are our options for
redundancy or fault tolerance?
A: The CyberGatekeeper Server allows multiple appliances to be used
in a failover scenario. If the "active" appliance becomes
unavailable, the standby automatically becomes active and takes
over tasks from the unavailable unit. This occurs in less than a
minute and is generally seamless to the end user.
Q: What central management
facilities are provided in CyberGatekeeper?
A: Policy Manager can develop, deploy and manage policies for any
number of CyberGatekeeper Servers. Policies can be grouped together
into export sets, which allow rapid deployment to multiple appliances
in a single action. The appliances themselves are managed directly
via telnet or SSH, but configuration changes at this level are rarely
needed.
Q: Is CyberGatekeeper secure?
A: All communication and traffic between the CyberGatekeeper Agent
and Server is signed and encrypted to provide privacy and integrity.
CyberGatekeeper Server is normally placed within the corporate network
behind the firewall or VPN gateway. CyberGatekeeper Server is hardened
and resistant to attack.
Technical: User Desktop
Q: What endpoint platforms
does the solution support?
A: There are three types of auditing methods for the client: 1)
dissolvabale client audit, 2) an agent on the network device, and
3) white list of the device ID for network devices that cannot run
the agent. The agents providing full functionality run on Windows
2000, XP, 2003, and Vista. The MACOSX and Linux agents support in-line
NAC, and will support Dynamic NAC 3Q 2007.
Q: How much CPU does the audit
process take?
A: When idle or during a session, the CyberGatekeeper agent takes
up less than 2% of CPU time. When a new session is initiated, it
uses more CPU, for a short period (about 1 second). It then drops
to the nominal idle usage.
Q: Can CyberGatekeeper Server
log to a central location?
CyberGatekeeper Server logs to a central reporting server.
Technical: Policy Management
Q. What is Policy Manager?
A: Policy Manager is a Windows based tool used to develop, deploy
and manage policies that determine what to check for in endpoint
devices and how to determine compliance. Policy Manager also builds
custom agents that can be tailored to meet site specific requirements.
Q: How does the agent check
if the PC is compliant with the policy?
A: There are a variety of tests available that may be defined in
the policy definition with Policy Manager. The available tests include:
- Check process or file – Used to check that a process
is running or a file is present on the remote PC. Specific characteristics
of the process or file such as date/time stamp, size, version
and checksum may be analyzed.
- Check registry key – Used to check for the absence, existence
or value of a specific registry key.
- Check operating system – Used to check for major and
minor version of the operating system running on the remote PC.
Includes checking for Service packs and updates.
- Check computer name – Used to check the computer name
setting in Windows.
- Check ini File – Used to check the contents of a standard
.ini file.
- Check network – Used to check the TCP/IP settings of
the computer.
Q: Does the agent check for
the version of virus scanner .dat files and scan engines? What happens
when you are in the process of updating your .dat files?
A: Yes, using the policy definition options described above, the
virus scanner .dat files can be checked. Updating the .dat file
will have no effect on the agent periodic checking process; however,
if the update of the .dat file violates the policy definition, then
network connectivity will be affected. For that reason it’s
recommended to define a minimum required version in the policy instead
of a specific version. Another option to enforce .dat files is to
define the maximum number of days old that it is deemed safe.
Q: Can the solution distinguish
between systems as to which should be checked and other systems
which should not be checked? How?
A: Each policy consists of two criteria: conditions and requirements.
The conditions indicate under what configurations the policy should
be applicable. The requirements indicate what should be enforced
for the applicable policy. It is possible for administrators to
create different policies for different systems depending on the
conditions present on that system. For example, a specific policy
can be defined for Windows XP systems, and another one for a pilot
pool of users.
Q: Is it possible to have
more than one policy?
A: Yes. Policy definitions are managed by Policy Manager and downloaded
to the CyberGatekeeper Server. An unlimited number of policies can
be created with Policy Manager.
Q. How does CyberGatekeeper
Server remediate infected or non-compliant machines?
A: Each component of a policy can have a remediation action associated
with it. If a user fails the audit because of this component, the
remediation will automatically be performed. This typically consists
of downloading an executable file (such as an installer or patch)
on the endpoint system.
Consider this example: A user logs out and goes home at the end
of the business day. During the night, a new policy is pushed out,
which requires a patch that the user's system does not have. As
a result, the endpoint will fail the audit and be placed on the
quarantine network.
The configured remediation action will automatically start. In
this case, the remediation action could be to download and install
the patch that was required, but missing on the endpoint system.
Once the patch has been installed, the system is re-audited. If
it passes, it is then placed back on the corporate network. The
next morning, when the user logs in, they have no idea that their
system has been patched automatically during the night.
