The Invisible Achilles’ Heel of Network Security

The Invisible Achilles’ Heel of Network Security

Not too long ago, we tweeted an article about the biggest hacks of 2018 and  yet another has just been revealed. This is becoming commonplace. The trend seems to be indicating that too many people have become complacent in their security protection. Hacking of any company’s data is BIG business – more so than most people realize.

According to CSO Online  about 58 records are stolen EVERY SECOND! Even though smaller breaches go unreported, larger ones are usually reported and, at an estimated average cost of $141 per record, the bill for a breach can be staggering.

Sticking your corporate head in the sand and saying “It won’t happen to me” is a big mistake. It is far better to put resources in place to ensure you have done everything you can, to defend yourself. Unfortunately, firewalls, anti-virus, anti-malware, strong passwords, biometric devices, and physical security measures are not always good enough. As a business manager (or owner) you also need to train your IT staff in what to look for that may indicate a threat, what to do during an attack, and how to mitigate potential future intrusions… BUT there is another layer of weakness that is often overlooked…

You may remember the story, from Greek mythology, of Achilles. He was the baby who, it was foretold, would die young. His mother took him to the river Styx, and dipped him in, holding him by the heel, in the hope that the magical water would give him the power of invincibility. Into adulthood, he survived many battles however, one day, a poisonous arrow was shot at him and hit him in the (un-dipped) heel. He died soon afterwards.

Forbes  revealed that, even after you have spent money on putting a strong security protocol in place to protect your company, and trained your IT team, your other (non-IT) employees can cause your company’s security downfall. Any employees who fail to follow simple security-oriented steps (either accidentally or deliberately) can cause gaping holes in otherwise competent network security.

It doesn’t matter how big or small your company is, employees can still be the cause of major weaknesses in your network security. Even if you think that training them is going to be more than the current budget can handle, that price, whatever it may be, is still going to calculate out as being significantly less than the cost of mitigating the devastating result of a full-scale breach.

Some of the old phrases or “sayings”, that we all heard our Grannies tell us, containing their sage wisdom, have never been more appropriate: “a stitch in time, saves nine” advises us that it is better to make your employees aware of the basics BEFORE they let you down, and potentially cost you a fortune, than leaving it until it is too late, and then being forced to “close the barn door after the horse has bolted”!

Training ALL your employees < not just your IT team > in network security is essential, because your company may already possess its invisible “Achilles’ heel”.

Wi-Fi Myth Series - Myth #8: Wi-Fi 7 Will Fix My Wireless Problems

By Rie Morgan • July 30, 2026
Every new Wi-Fi generation arrives with a wave of excitement: faster speeds; lower latency; more efficient use of the spectrum; and better handling of dense environments. Wi-Fi 7 is no exception. It brings some genuinely impressive technological advances but, unfortunately, it also brings a familiar myth: "If we upgrade to Wi-Fi 7, all of our wireless problems will disappear." If only wireless engineering were that simple. Wi-Fi 7 is an outstanding technology, but it isn't a magic wand. Poor design, interference, bad client behavior, and unrealistic expectations don't suddenly vanish because the APs have a shiny new logo on the box. Let's bust another myth...

Wi-Fi Myth Series - Myth #7: Roaming Problems are Always Client Problems

By Rie Morgan • July 23, 2026
Few phrases trigger a knowing smile from experienced Wi-Fi engineers quite like this one, "It's the client's fault." Someone's video call drops while walking through the office or a warehouse scanner pauses between aisles, voice handsets crackle as users move from one floor to another... then, almost immediately, someone points at the device and confidently declares, "Well... clients decide when to roam." Technically, they're correct. But, practically, that's only part of the story. Roaming is one of the most fascinating aspects of Wi-Fi because it isn't controlled by a single device or a single setting. It's a partnership between the client, the infrastructure, and the RF environment. When that partnership breaks down, blaming one side rarely tells the whole story. Let's bust another myth... Yes, Clients Make the Decision Let's start with the important truth: in almost every Wi-Fi deployment, the client device ultimately decides when to leave one AP and join another. Laptops, smartphones, tablets, barcode scanners, medical devices, and countless IoT products all use their own roaming algorithms. Some roam aggressively whereas some cling to their current AP for far too long. Others seem convinced that losing the connection entirely is preferable to switching. Every Wi-Fi engineer has encountered at least one stubborn client that appears almost “emotionally attached” to a particular AP. :) Client behavior matters, but that's not where the story ends.

Wi-Fi Myth Series – Myth #6: A Site Survey Is Optional

By Rie Morgan • July 17, 2026
Every Wi-Fi engineer has heard some version of it, "Can't we just install the access points where the old ones were?" Or perhaps, "The floorplan looks straightforward. Let's save some time and skip the survey." Occasionally, someone even says the dangerous words, "We've done hundreds of these buildings. They're all basically the same." That's usually the point where experienced wireless engineers quietly smile, knowing that the building is about to teach everyone a valuable lesson because: buildings don't read design guides, concrete doesn't care about your deployment schedule, metal doesn't respect your project budget, and radio waves have never once agreed to cooperate, simply because everyone wanted them to. Let's talk about why a site survey isn't an optional luxury... it's one of the most valuable engineering tools available. Every Building Is Different At first glance, two office buildings may appear identical: same square footage, same number of floors, similar room layouts, yet their wireless behavior can be dramatically different: one may have reinforced concrete walls, another may contain extensive glass partitions, the warehouse may be filled with moving inventory, a hospital may have elevators, imaging equipment, and countless reflective surfaces, a manufacturing facility may contain machinery that wasn't mentioned on any floorplan, and remember: even furniture changes RF behavior! Anyone who has performed enough surveys eventually develops a healthy respect for one simple fact: the building always gets a vote, too!
