SECURITY & PRODUCTSSince the dawn of the internet we have been populating our networks with all kinds of neat equipment.
PUBLIC Copyright © 2017 Rockwell Automation, Inc. All Rights Reserved. 37
SECURITY & PRODUCTSWhat do all of these neat things have in common?
They can ALL be exploited if they aren’t secured.
PUBLIC Copyright © 2017 Rockwell Automation, Inc. All Rights Reserved. 38
SECURITY & PRODUCTSWhy secure them? To secure them from what?
Some devices like PLCs were created from an open platform. They send and receive clear text data. Often times, usernames and passwords are included.
PUBLIC Copyright © 2017 Rockwell Automation, Inc. All Rights Reserved. 39
SECURITY & PRODUCTSWhy you need to think about the security of your devices on the factory floor.
Devices are added to company networks without strong controls from the use of routers and deep packet inspection.
Some devices have remote access, in many cases, it makes them accessible by anyone, anywhere.

SECURITY – OPEN PORTS
The Open Port Search Engine, Shodan, was launched in 2009 by a computer programmer, John Matherly, who in 2003,[4] conceived of the idea to search for devices linked to the Internet. It started as his pet project based on the fact that large numbers of devices and computer systems are connected to the Internet.
Shodan users are able to find systems including traffic lights, security cameras, home heating systems as well as control systems for water parks, gas stations, water plants, power grids, nuclear power plants and particle-accelerating cyclotrons.

• NAT: Network Address Translation (NAT) provides, • Remote support capabilities of control systems • Flexibility to allow the placement of identical machines on a Ethernet network without network setting changes • Ability to apply consistent configurations to control systems on a network, allowing for exact duplications of
machines / processes• Reduces the need for “public” IP addresses
• Routing/VLAN Routing Provides,• Ability to converge two or more distinct IP scheme into the same network• Ability to converge two or more distinct VLANs into the same network
• Access Control Lists Provide• Grant or restrict access to any of the 65535 destination ports of a TCP/IP Address
• Firewalls Provide• DeMilitarized Zone (DMZ) between the internet and controls network• DeMilitarized Zone (DMZ) between the IT and OT network

• Filtering can be done by examining such things as:
- Source IP, MAC ID, or port- Destination IP, MAC ID, or port - Upper layer protocol

• How many work cells are involved? ANSWER: 4 or more
• Do all of the work cells have unique private IP addresses? ANSWER: 2 or more similar or dissimilar IP’s
• How many devices (nodes) are in the work cell?ANSWER: The 5700 configuration can support an almost limitless amount of nodes. It’s true limit is the switch processor utilization and the amount of data the needs to flow between the private and public networks.
• Are you planning on using a single appliance?ANSWER: If YES, The 5700 configuration can support multiple NAT Tables, meaning it is able to bring multiple work cells together into one public address .
