Network Architecture review in context of Information security helps to understand how to actually review the components of network with respect to best practices.
This slide explains the design part as well as implementation part of the firewall. And also tells about the need of firewall and firewall capabilities.
Firewall is a device or set of instruments designed to permit or deny network transmissions based upon a set of rules and regulation is frequently used to protect networks from unauthorized access while permitting legitimate communications to pass or during the sensitive data transmission. Distributed firewalls allow enforcement of security policies on a network without restricting its topology on an inside or outside point of view. Use of a policy language and centralized delegating its semantics to all members of the networks domain support application of firewall technology for organizations, which network devices communicate over insecure channels and still allow a logical separation of hosts in- and outside the trusted domain. We introduce the general concepts of such distributed firewalls, its requirements and implications and introduce its suitability to common threats on the Internet, as well as give a short discussion on contemporary implementations.

In computing, a firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic based on applied rule set. A firewall establishes a barrier between a trusted, secure internal network and another network (e.g., the Internet) that is not assumed to be secure and trusted.
Many personal computer operating systems include software-based firewalls to protect against threats from the public Internet. Many routers that pass data between networks contain firewall components and, conversely, many firewalls can perform basic routing functions.

A firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. Packet filter is a hardware or software designed to block or allow transmission of packets based on criteria such as port, IP address, protocol.
Understanding IT Network Security for Wireless and Wired Measurement Applicat...cmstiernberg
The line between the once mutually exclusive IT and engineering departments is beginning to blur as PC-based technologies familiar to the IT sector find their way into measurement applications. Learn how to create synergy between these two groups by understanding how enterprise security protocols apply to wireless/wired measurement systems.
This project aims at cracking the Wi-Fi security(WEP,WPA-personal).It basically includes
intrusion in a BSS(Basic Service Set),monitoring the traffic in air, manipulate SSIDs, get details
of clients on a particular SSID, sniffing the packets to & from them to Access point, creating a
false access point, detect hidden SSIDs etc.
Long term goal of the project (part of the project which will be implemented in next semester) is
that once the security is breached and we are able to communicate with the victim we will try to
take over the control of the victim’s system and try to manipulate the data in his system.
Wireless Security Best Practices for Remote Monitoring Applicationscmstiernberg
Wireless network security continues to be an area of intense research and development, particularly in applications where wireless sensors are extending the reach of traditional monitoring and control systems. While the IT sector has embraced the IEEE 802.11i standard for corporate networks, engineers have many more options available to them for their industrial network designs. This presentation will provide an overview of IEEE 802.11i, IEEE 802.15.4, ZigBee, and other security protocols as they relate to measurement and automation applications. In addition, network design and commissioning best practices will provide attendees with a set of recommendations for guarding against the most common security attacks.
2. Introduction
• A physical security system is actually a network of embedded devices that
were designed, implemented and deployed with no cyber security in-mind
• These devices has minimal (if any) security mechanisms which makes
them exposed to cyber attacks that might decrease the physical security
level in the site
• The network in exposed to threats coming from outside (connections to
other networks and remote access) and from inside (connected devices,
servers and workstations and from unsecured network equipment)
• Physical security systems are predictable in their operation which makes
the network to be predictable and this makes it easier to secured them
while relying on searching for abnormal behavior

3. Vulnerabilities – IT Aspect
• Infected devices can attack the network by a DoS attack or a stream of bad
Ethernet packets
• DHCP attack may end up with an upload of Trojan software to a valid
device or to IP misconfiguration attack
• ARP poisoning / MAC spoofing attacks may allow injection of false data to
the network or interception of data
• Forgotten remote connection might expose the network to threats from the
internet (or any remote network)
• Using default or weak passwords might expose the system to various
attacks including taking over devices
• Network connections (wired and wireless) are exposed to attacks
especially in the outdoor environment

4. Vulnerabilities – Physical Security Aspect
• DoS attack = Loss of alarms, video stream and ability to control devices
(i.e. PTZ IP cameras)
• DHCP attack = Injection of false data (alarms, video) to the security system
and/or creating network failure
• ARP poisoning / MAC spoofing attacks = Injection of false data (alarms,
video) and interception of data (viewing video stream)
• Forgotten remote access connection, Using default or weak passwords,
Network connections = All of the above…

5. The Senstar Solution
• Senstar offers a unique solution to cyber secure physical security systems
while taking advantage on the unique network behavior of such networks
• The solution focuses on sealing the network and assuring that only valid
devices and data streams will be part of the network by providing security
to each of the network layers (in the OSI 7 layers model)
• The solution does not affect the operation of the physical security system,
the structure of the network and does not add more hardware or software
components
• The solution takes the “human factor” (AKA as “layer 8” in the OSI 7 layers
model) out of the security equation and eliminates the affect of user
passwords on the security of the system and network

7. Tungsten, just another switch?
Slide 7
1. Tungsten is a ruggedized cyber
security appliance for the edge
of the network
2. It is not “just another switch”, it
seals the network in both physical
and logical ways
3. Since building networks require
switches, the cyber security was
embedded into a switch
8. Securing the Physical Layer
8
• Our patented approach offers a simple, yet powerful level of security to the
edge of the network
• The philosophy behind this unique cyber security approach is to seal the
network rather than dealing with the user settings (i.e. passwords) and
applications
• Based on the physical layer security we are offering several applications
including a robust but cost sensitive dark fiber protection (compliant with
the NERC/FERC CIP)
Closing the door!
9. Cyber Security in 5 Simple Steps
• Install the Tungsten switches instead of non-secured Ethernet switches
(mainly at the edge of the network)
• Turn on the Tungsten, configure the security level per each port and let it
map the network (in most cases it takes about 1 second)
• View the list of discovered connections (including the mapping of the
cables and fibers) and approve it
• View the list of discovered devices (including the mapping of the Ethernet
and IP addresses) and approve it
• View the list of discovered data streams (including the TCP/IP
characteristics) and approve it
• Done… It takes 5 minutes to secure a network.
