The legacy endpoint devices that control our critical infrastructure (utility systems, water treatment plants, military networks, industrial control systems, etc.) are some of the most vulnerable devices on the Internet. These devices present a vast attack vector that’s not adequately protected. Many of these are:
fixed-function devices that can’t be upgraded to add security;
devices that use obsolete operating system (OS) versions that are insecure and can’t be upgraded;
real-time OS-based devices that were designed before security was a critical concern and therefore lack sufficient security;
designed for use on private networks but are now connected to the Internet.
Once deployed, these devices remain in use for five, 10, or even 20 years. The cost to replace them all to add security improvements would be staggering. For devices that can’t be easily or affordably replaced or upgraded, a “bump-in-the-wire” appliance solution provides the required security.
Some OEMs offer products to protect these legacy devices by creating a “secure enclave” in which these devices can operate. Only trusted devices should be deployed within the secure enclave. These devices can freely communicate with each other; however, communication outside of the enclave is controlled for security. The bump-in-the-wire appliance provides security by enforcing communication policies, ensuring that only valid communication is allowed with the endpoints within the secure enclave.
By limiting communication to the secure enclave, the bump-in-the-wire appliance will:
Prevent probes and hacking drones from discovering endpoints. Hackers and automated drones send out ping requests or other messages to a range of IP addresses looking for responses. The appliance drops these requests making the endpoints undiscoverable.
Prevent access from unauthorized machines. Many fixed function devices only need communicate with a few known, trusted hosts. Enforcing these communication restrictions prevents communication with unauthorized machines. If a hacker can’t communicate with the endpoint, they can’t compromise it.
Close security loopholes. Many cyberattacks utilize services on an endpoint that aren’t required for fixed function devices. Blocking unused ports and protocols closes these commonly exploited security loopholes.
Protect against denial of service attacks. By controlling whom the endpoint talks to, DoS attacks are blocked before they reach the endpoint. The endpoints are shielded from malicious traffic and traffic floods, ensuring continued operation even when the network is under attack.
Protects against insider attacks and malware on the corporate network. Endpoints within the secure enclave are sheltered from malicious packets that may be present on the corporate network. With communication restricted to a small set of trusted hosts, malware, insider attacks, or any other malicious activity is blocked. An insider attempting to hack an endpoint from outside the corporate network or from any non-trusted machine will also be blocked, preventing the attack.
Quarantine infected or compromised machines. If the appliance provides bidirectional filtering, it will enable any endpoint infected with malware or compromised by hackers to be quarantined, limiting damage from the attack.
Enhance security for endpoint devices. Fixed function devices, SCADA machines, and other critical endpoints can be grouped into a secure enclave. The communication policies for these machines can be more restrictive than the general policies for the rest of the network. This allows a higher level of security to be enforced for the critical devices on your network. Even if the front end of the corporate network is breached, the individual endpoints are still safe.
The main difference is that our solution will support all TCP/IP traffic, not just HTTP traffic. Our solution also supports flexible filtering rules that can be customized for SCADA and similar devices.
Manufacturers of plastic parts recognize the potential of conformal cooling to reduce molding cycle times. Problem is, conformal molds require additive manufacturing (AM), and technologies in that space are still evolving. Costs also can be high, and beyond that, many manufacturing organizations lack the knowledge and expertise needed to apply and incorporate additive technologies into their operations.
Machine vision and video streaming systems are used for a variety of purposes, and each has applications for which it is best suited. This denotes that there are differences between them, and these differences can be categorized as the type of lenses used, the resolution of imaging elements, and the underlying software used to interpret the data.
As today’s product design cycles are held to tighter schedules and budget constraints, it’s becoming even more critical to consider human factors up front to catch and fix problems during the initial development stages, when it’s faster and less costly to do so. Overlooking human factors at the beginning of the design cycle could lead to poor user experience, a decrease in effective product performance, and an increase in safety risk to the user.
Plastic part manufacturers are always looking for ways to reduce cycle time and get more productivity out of their injection molding machinery. One of the longstanding constraints in injection molding production has been cooling time. Removing parts from the mold before they have cooled induces warping or shrinking. But wait time works against productivity.
