Cybersecurity (Firewall, DMZ)
The security and integrity of industrial information is of vital importance for the advancement of information technology, IoT and industry 4.0 in processes.
Cybersecurity is the set of procedures and tools that are implemented to protect the network infrastructure and information that is generated and processed through computers, servers, mobile devices, networks and electronic systems.
It is important to take into account 4 main points, which help to guarantee the security of the information:
Only authorized users can access resources, data and information.
Only authorized users should be able to modify the data when required.
The data should be available to users when needed.
Verify that you are really communicating with who you are meant to.
What you want to protect:
Threats do not always arrive by physical means, to guarantee the security of the software, it is important to apply the security measures corresponding to these environments, for example, making use of antivirus software, creating rules to allow or deny access to certain internet pages that are not reliable. One of the main risks that we can find here is not having updated equipment.
Provide protection to the entire network infrastructure, starting with communication devices such as routers, switches, servers and / or controllers. For this it is important to have the use of Firewalls who will be in charge of preventing threats and intrusion into the network.
Apply those good practices that lead us to protect data on the network, and thus, offer those 4 specific points of information security: confidentiality, integrity, availability and authentication.
Network security involves keeping our environment free from viruses, spyware or adware, denial of service attacks, or identity theft.
There are many threats that are there, waiting to find that minimum vulnerability to be able to attack their target. Any IT / OT communication network is not free of threats and each one is responsible for the security that it applies to its infrastructure.
Previously, sharing process information with the outside (Internet) was something that for security reasons was not possible. Now with Industry 4.0 that seeks to have the majority of equipment connected to the network and provide access to the cloud to have information from any point outside the plant, it implies having a network that allows us to share information in a secure way outside.
The implementation of a security network or demilitarized zone (DMZ) that is totally independent from your plant network (OT) will serve to delimit the perimeter with the enterprise network (IT / INTERNET).
Within this DMZ zone, with the use of firewall devices, you can analyze, identify, allow or deny incoming or outgoing network traffic. From the design of the network architecture, it is important to take into account the devices that will have the function of protecting the infrastructure and the information that we are generating and transmitting about it. If for any reason your infrastructure does not have security devices, at ECN Automation we can provide you with advice to implement that security network that the system requires.
