barox Kommunikation AG, the manufacturer of IT switches designed specifically for the demands of video networks, has introduced ‘Smart Sticky’ MAC & IP address Enterprise-class network security.

Supporting built-in Cyber security on all barox RY-switches, barox powerful Smart Sticky MAC & IP address learning adds an additional layer of high security.

An easy automatic process via the barox DMS GUI, once configured, barox Smart Sticky learns the dynamic MAC addresses of all connected ports/devices and VLANS, turning them into secure MAC addresses, adding each secure MAC address to the running configuration, and freezing them and their associated IP addresses – making them, ‘Sticky’.

Advanced port and network security

Smart Sticky with its combined MAC and IP address protection provides advanced port and network securityWhile traditional device protection via MAC filtering alone offers simple protection against unwanted network access, it does not, for example, protect against a widespread attack of ‘MAC spoofing’. Smart Sticky with its combined MAC and IP address protection provides advanced port and network security with Limit Control settings. With this functionality, Enterprise-class Cyber and physical security is provided with the port being shut down in the advent of the unplugging of a camera/device.

By learning the Mac and IP address of each and every port, it is not possible for a port to be hijacked. This prevents an ‘unknown’ device being able to access the network to attack the system for spoofing/phishing, preventing it from being used for malicious attacks. Only devices with a known MAC and IP address will operate on the network.

If non-managed switches are connected to terminal devices at the barox switch, Limit Control can be used to block free IP/Ethernet terminals, and prevent access to the network ports of those non-managed switches.

Port protection against unauthorized usage

The barox Smart Sticky function is able to learn the entire MAC and IP address configuration of all ports on a networkbarox Smart Sticky provides a very high level of Cyber and physical network protection for use within a wide variety of applications,” says Rudolf Rohr, barox Co-founder & Managing partner. “This is particularly the case where outdoor networks like car parks would leave devices such as cameras open to threat, where they could be unplugged, and a rogue device plugged in.

On activation, the barox Smart Sticky function is able to learn the entire MAC and IP address configuration of all ports on a network. In addition, limits can be set to make sure that any unused ports are blocked, to prevent their use and access to the system, while active ports are fully protected against unauthorized usage. Switch rules can also be set to govern specific port IN/OUT TCP streaming, and a White/Blacklist set-up. And furthermore, any changes to network/device configurations need to be authorized to take effect.

Water Plant Attack Emphasizes Cyber’s Impact On Physical Security
Water Plant Attack Emphasizes Cyber’s Impact On Physical Security

At an Oldsmar, Fla., water treatment facility on Feb. 5, an operator watched a computer screen as someone remotely accessed the system monitoring the water supply and increased the amount of sodium hydroxide from 100 parts per million to 11,100 parts per million. The chemical, also known as lye, is used in small concentrations to control acidity in the water. In larger concentrations, the compound is poisonous – the same corrosive chemical used to eat away at clogged drains. The impact of cybersecurity attacks The incident is the latest example of how cybersecurity attacks can translate into real-world, physical security consequences – even deadly ones.Cybersecurity attacks on small municipal water systems have been a concern among security professionals for years. The computer system was set up to allow remote access only to authorized users. The source of the unauthorized access is unknown. However, the attacker was only in the system for 3 to 5 minutes, and an operator corrected the concentration back to 100 parts per million soon after. It would have taken a day or more for contaminated water to enter the system. In the end, the city’s water supply was not affected. There were other safeguards in place that would have prevented contaminated water from entering the city’s water supply, which serves around 15,000 residents. The remote access used for the attack was disabled pending an investigation by the FBI, Secret Service and Pinellas County Sheriff’s Office. On Feb. 2, a compilation of breached usernames and passwords, known as COMB for “Compilation of Many Breaches,” was leaked online. COMB contains 3.2 billion unique email/password pairs. It was later discovered that the breach included the credentials for the Oldsmar water plant. Water plant attacks feared for years Cybersecurity attacks on small municipal water systems have been a concern among security professionals for years. Florida’s Sen. Marco Rubio tweeted that the attempt to poison the water supply should be treated as a “matter of national security.” “The incident at the Oldsmar water treatment plant is a reminder that our nation’s critical infrastructure is continually at risk; not only from nation-state attackers, but also from malicious actors with unknown motives and goals,” comments Mieng Lim, VP of Product Management at Digital Defense Inc., a provider of vulnerability management and threat assessment solutions.The attack on Oldsmar’s water treatment system shows how critical national infrastructure is increasingly becoming a target for hackers as organizations bring systems online “Our dependency on critical infrastructure – power grids, utilities, water supplies, communications, financial services, emergency services, etc. – on a daily basis emphasizes the need to ensure the systems are defended against any adversary,” Mieng Lim adds. “Proactive security measures are crucial to safeguard critical infrastructure systems when perimeter defenses have been compromised or circumvented. We have to get back to the basics – re-evaluate and rebuild security protections from the ground up.” "This event reinforces the increasing need to authenticate not only users, but the devices and machine identities that are authorized to connect to an organization's network,” adds Chris Hickman, Chief Security Officer at digital identity security vendor Keyfactor. “If your only line of protection is user authentication, it will be compromised. It's not necessarily about who connects to the system, but what that user can access once they're inside. "If the network could have authenticated the validity of the device connecting to the network, the connection would have failed because hackers rarely have possession of authorized devices. This and other cases of hijacked user credentials can be limited or mitigated if devices are issued strong, crypto-derived, unique credentials like a digital certificate. In this case, it looks like the network had trust in the user credential but not in the validity of the device itself. Unfortunately, this kind of scenario is what can happen when zero trust is your end state, not your beginning point." “The attack on Oldsmar’s water treatment system shows how critical national infrastructure is increasingly becoming a target for hackers as organizations bring systems online for the first time as part of digital transformation projects,” says Gareth Williams, Vice President - Secure Communications & Information Systems, Thales UK. “While the move towards greater automation and connected switches and control systems brings unprecedented opportunities, it is not without risk, as anything that is brought online immediately becomes a target to be hacked.” Operational technology to mitigate attacks Williams advises organizations to approach Operational Technology as its own entity and put in place procedures that mitigate against the impact of an attack that could ultimately cost lives. This means understanding what is connected, who has access to it and what else might be at risk should that system be compromised, he says. “Once that is established, they can secure access through protocols like access management and fail-safe systems.”  “The cyberattack against the water supply in Oldsmar should come as a wakeup call,” says Saryu Nayyar, CEO, Gurucul.  “Cybersecurity professionals have been talking about infrastructure vulnerabilities for years, detailing the potential for attacks like this, and this is a near perfect example of what we have been warning about,” she says.  Although this attack was not successful, there is little doubt a skilled attacker could execute a similar infrastructure attack with more destructive results, says Nayyar. Organizations tasked with operating and protecting critical public infrastructure must assume the worst and take more serious measures to protect their environments, she advises. Fortunately, there were backup systems in place in Oldsmar. What could have been a tragedy instead became a cautionary tale. Both physical security and cybersecurity professionals should pay attention.
