Trend Micro has taken the multilayered security approach to the next level of
sophistication with its Trend Micro Threat Management Services network security
Threat Management Services provides an additional security layer that greatly
strengthens an organization's security infrastructure by monitoring the network for
active infections that have successfully infiltrated. Once the threat discovery occurs,
in real time, the network overwatch layer intercepts the attack and performs
automated containment and remediation.
BACnet itself is a living standard undergoing constant growth and revision under the
auspices of ASHRAE Standing Standard Project Committee (SSPC) 135. This committee
is made up of building control industry vendors, BCS users, academics and government
representatives. The BACnet standard has been designed specifically to meet the com-
munication needs of building automation and control systems for applications such as
heating, ventilation, air conditioning control, lighting control, access control, and fire
What does a typical BCS network look like? Most installations today have a dedicated
BCS network with centralized control via an operator’s terminal in the facility manager’s
office. There is no Internet (or LAN) connection, and thus no IT threat. However, the
trend today is toward greater connectivity to enable new services, convenience, and
savings on infrastructure costs. Newer buildings have network connections to the Inter-
net. But even so, most BCS networks still have few resources that are of value to the
Taking the network scenario of Figure 1, there will be web interfaces (routers and serv-
ers), BACnet/IP controllers (connected to interesting devices that are network accessible),
and operator workstations that may have vulnerable OS as well as configuration files and
other interesting data and resources.
The following table is adapted from a Drexel report on network security [Eisenstein et al.,
2003a] and lists known IT threats to a BACnet network connected to the public Internet.
After the installation of Outpost Network Security is complete, you can configure the centralized
automatic updates so when Outpost Network Security Client is installed on user workstations all
available updates will be immediately applied so your network and each workstation always has
the strongest and latest security. Centralized updates decrease network traffic. Agnitum Update
Service provides automatic download and installation of each available update on all computers
in your network.
New, multilayered security architectures are raising the bar in demonstrating "best
efforts" to protect enterprises from attacks. These new approaches to enterprise
security are now demonstrating their enhanced overall effectiveness when compared
with existing and earlier enterprise security architectures.
In the new and enhanced security architecture, the existing in-line threat detection
forms the first layer and the overwatch component forms the second layer.
Home computers that are connected to the Internet are
under attack and need to be secured. That process is
relatively well understood, even though we do not have
perfect solutions today and probably never will.
Meanwhile, however, the home computing environment
is evolving into a home network of multiple devices,
which will also need to be secured. We have little
experience with these new home networks and much
research needs to be done in this area. This paper gives
a view of the requirements and some of the techniques
available for securing home networks....
This module provides students with an appreciation of the challenges that are
involved in maintaining a secure and reliable system.
After completing this module, students will be able to:
Use Group Policy to apply security policies to secure the user environment.
Use Group Policy to configure password and logon account policies.
Analyze security log files to detect security breaches.
Secure the logon process by using smart cards.
Apply service packs, hotfixes, and antivirus software.
This paper is the second in a three-part series of white papers, each of which focuses on a functional area of
securing your network. As introduced in the first installment, network security should be implemented throughout
your entire network. Take a layered approach and introduce security at every layer possible. This second
paper will suggest steps to secure your Router, Firewall, and Virtual Private Network (VPN) Concentrators.
The requirements for a network administrator have always been diverse. Get the users connected, make sure there’s enough bandwidth to run applications, keep the network secure, and so on.
When problems come up on a traditional network, the solutions have often been fairly straightforward. If users aren’t connected, you connect them. If there’s not enough bandwidth, you buy new equipment. If network resources are vulnerable, you introduce appliances and applications that provide enhanced security. It’s a pretty
tight loop of problems and solutions....
You are the network administrator for The Meely Meal company. Owned by Milton Meely, the company is a leading
distributor of wheat germ and other grains and cereals. The company has three locations:
1. Corporate Headquarters in Albuquerque, New Mexico.
2. A packaging and distribution plant in Battle Creek, Michigan.
3. A small purchasing office in Lincoln, Nebraska.
A diagram of the network is included below.
Milton has hired his son, Matt, as an intern for the summer. Matt tells you that he is thinking of getting his CCNA. He
says that he plans to prepare by reading "the" book.
