Like you said it would take decades to maybe get one fully functional.Īll times are GMT -4. S7 Trends is a free and easy-to-use software to trace what is going on in Siemens PLC. Im sure with projects that depend on quick scan times, tablets may still be lacking in terms of technology. Although their should be limitations on what it can do. As far as programming through a tablet, it actually sounds really cool. Imagine an employee working on the station and someone turned it on? These are just thoughts, that go through my mind. The fact that a system can be function through remote can be dangerous. Firewall Network settings The table below shows the STEP 7 network settings you need to analyze network security and. In my opinion I don't really approve of this remote connection as it can be an issue in terms of safety. although im sure if people are simply going on the web server url it would for sure impact the scan time.

I assumed their would be a password involved when accessing the web server. Learn how Fortinet next-generation firewall (NGFW) products can provide high-performance & consolidated security. I absolutely agree, and I seem to notice the scan time difference with the web server running in the back ground. I constantly hear people wanting to do PLC programming from a tablet, though, and, eventually, someone will give it to them. No clue if anyone is working on this right now, but I assume it's at least a decade out in the mainstream. Dillon outlined other serious vulnerabilities as well, most of which is well documented in Beresford Black Hat, Part I: Details. This should have never been allowed through the Siemens development and Quality Assurance process.

In my mind, the PLC of the future will be able to run a full HMI from a web page via HTML5, and will also have programming/configuration access via the a web app as well. Letting unnecessary services run on a PLC and the use of hardcoded passwords are both basic security errors.

Seeing the diagnostics and CPU messages is huge, and the ability to have custom user web pages that can access tag data is potentially revolutionary, although also potentially scary.

PLC web pages are a cool feature, though, don't get me wrong. I'm not sure how many users are supported at one time. This can affect your scan time, so make sure you design your application accordingly. Note also that the web pages do take up CPU resources every time a page is loaded. Most of the published security vulnerabilities for PLCs (of any brand) have been related to built in web pages. Unless you have a firewall in place (and configured correctly), anyone who can access the web page could also try to go online with the PLC. Siemens shall exhibit an integrated security management system at Security 2010 Security and fire safety solutions take centre stage on the Siemens stand at Security 2010 in Essen. I know we discussed the VPN yesterday but I wanted to see if this siemens web server could be a possible solution without using outside VPN support.īe careful with the security of the web pages on the open internet.
