We manage WANs and LANs for global enterprises, no matter what vendors and platforms you use.
A less vulnerable network loses fewer data and, in general, is less exposed so that no havoc is caused at this level, which would not only be cheap but can go much further depending on the attack received, so is important to protect their systems and data, and there are resources for this at sites like https://www.fortinet.com/resources/cyberglossary/sd-wan-explained.
At the very least, a larger attack on critical infrastructure can cause disruption and put the IT assets at risk, but what about “redundant” systems where we have a system or technology that is redundant, which can still fail but without catastrophic loss of data or destruction of infrastructure? While the report states that these are as vulnerable as systems on a conventional network, what happens if the failover fails?
An incident on a cyber-grid could spread disruption to power generation, rail networks, or other key infrastructure assets and infrastructure because the failure mode could be unpredictable and destructive.
Still with me? Let’s review:
Failure mode: Non-systematic or “broken link” in a chain-repetition-transmission model.
Not-systematic: There is no evidence of an intentional attack, except for a very few cases.
Critical Infrastructure: Cyber-grid failure affects power generation, rail, communications, financial and other crucial assets, with loss of data leaving the customers without power or reliant on backup systems.
Cyber-grid: In case of any failure, failure modes include “systematic” and “broken link” which aren’t present in conventional infrastructure or networks.
There is no way to know what would happen because no one’s testing those levels, except some people talking.
What is that test to verify? I guess it’s like knowing if a car works but with different components, and without a human operator.
I’ve heard the “breakpoint” concept used, and “path forward” sometimes when I’m asked to point out the shortcomings of the cybersecurity approach.
“Back in 2010, during an event known as the Bellagio blackout, there was no way to know exactly where the outage was coming from. The team in charge of testing for such incidents was not familiar with the Internet, where the real-time capability of such services was limited and testing wasn’t comprehensive. What happened? A group of hackers took control of a router in one part of the network and used it to send a massive surge of traffic from a different part of the network, knocking out 100s of back-ups in seconds. Had a similar event happened on the public Internet, we would have seen complete chaos.” IT security expert John Diggs, speaking on Bloomberg on June 26, 2014.
So, what happened? Had we had a network with a system to failover (say, a petri dish that could “failover” to other different systems in a secure and reliable way), a disaster would have been avoided with far less disruption to consumers, businesses and the economy than if there had been an Internet outage. Many businesses are turning to managed network security services to secure their networks.
How can we really trust a central government to keep its promise?
“All we can say for sure is that our Federal government is open for business. And all we can say for certain is that the Constitution was not violated and that the cybersecurity program is working.” Vice President Joe Biden, on May 16, 2014.
It’s worth pointing out that the cybersecurity agencies and their critics are often at odds. While the U.S. government has yet to announce a major incident where a government or contractor system was compromised by cyber-criminals, some security experts and lawmakers complain that there is not enough transparency and privacy protections for consumers and businesses.
When it comes to network management, Halo handles it all. From design and configuration to activation, monitoring, and support, we live and breathe networking so you don’t have to. Not only that, but we also provide complete visibility and analytics, so you’re never in the dark about your network or application performance.
At Halo, our consultative approach ensures that your needs dictate the technology we deliver — not the other way around. We meet with you monthly to review your settings and fine-tune your applications. You’ll even benefit from proactive alerts, carrier circuit remediation, and around-the-clock support every day of the year.
Why waste another minute worrying about your network when Halo offers account management paired with ongoing optimization and enhancement? Simplify your network management today by making the switch to one portal, one invoice, and one number for support with Halo’s managed network services.
Our carrier-agnostic SD-WAN solutions provide your customers with fully managed configuration, installation, and support.
Help your global customers stay secure and online across all locations, while their business has one point of contact and only receives one bill.
Technology changes can be scary. Let our engineers provide you with a detailed roadmap and an executable plan, streamlining your business and reducing OPEX costs.
Here’s what you reduce with SD-WAN:
Reduced bandwidth needs at hub or data center locations
Employee time struggling to get carriers to execute on service issues
Employee time trouble-shooting connectivity issues
Replacement of expensive or ineffective monitoring solutions
Time spent supporting and explaining issues to internal executives and employees
Loss of revenue due to network connectivity issues
Early termination fees to replace a failing vendors/carriers
Excessive surcharges and fees for which carriers are notorious
Expensive firewall systems
LAN infrastructure reduction
Cloud optimization and costs
Finally: a provider that actually delivers on what they say. Their client-first approach is such a relief compared to directly dealing with internet and SD-WAN providers. Halo’s attention to detail is refreshing, and they know how to communicate risk so a client can make informed business decisions. I highly recommend Halo Global as a managed SD-WAN solution provider.
