Creating Effective Passwords

It’s like a recurring nightmare-the whole issue of passwords simply won’t go away. People continue to use really awful passwords like secret and password because they’re easy to remember and they view passwords as a pain. A user will rely on the same password for everything, so once a hacker figures the password out, every resource the user can access is wide open. To make sure everyone can access the user’s account, the password often appears on post-it notes and in other obvious places. Of course, the user never, ever changes the password so once a hacker gains access, the accounts will remain open forever. This is just the tip of the password complaint iceberg.

Microsoft and other vendors are trying to remedy the situation by using biometric data or smart cards. The problems with smart cards are that they’re easily copied and even easier to lose. A lot of organizations have tried smart cards and found them to be less than ideal. Biometric data is just as bad and requires Biometric Authentication in order to check the security of your system. There are ways of easily thwarting fingerprint scanners today. Of course, once a fingerprint is hacked, you can’t change it. Fingerprints are unique, but using just a fingerprint means that everyplace you log in effectively uses the same password. So, once someone does hack your fingerprint, they can access absolutely everything you can. To overcome the issues with a single biometric, some researchers are now suggesting the use of a Multi-Biometric Authentication System (MBAS), which is also called a Multimodal Biometric Authentication System. So, how you have a really expensive, overly complex system that is bound to have a high failure rate.

The problem with all the various lines of thought out there now is what I call the magic bullet syndrome. Someone thinks that there is a solution that will somehow thwart the bad guys. Unfortunately, history proves that the bad guys always come up with a way to storm the gates and that any wall you build will prove too low at some point. I’ve advocated the passphase system for years because you can create passwords that are both strong and easy to remember. Passphrases can be quite long, complex, and still make it easy for someone to enter correctly nearly every time. In addition, you can change passphrases with the same ease that you can a password. Changing your password or passphrase relatively often means that even if hacker does gain access to an account, it’s unlikely to remain open to them. Still, no solution is perfect, which is why security monitoring is an essential part of any security solution.

Of course, whether you use a password or a passphrase, you need to know that it’s strong enough to keep hackers at bay, at least for a while. Therein lies another problem. According a recent ComputerWorld article, many of the password strength meters out there are giving users a false sense of security. They really don’t tell you that your password or passphrase is strong enough to withstand easy attack. When creating a password or passphrase, avoid using words that are spelled precisely the same as they are in the dictionary. For example, you could replace the letter E with the number 3. Make sure the passphrase is relatively long and complex. It should include spaces (when allowed) and special characters (such as the ampersand, &). Use a combination of uppercase and lowercase letters. Include numbers. Misspell a word or two, such as “MiG00dPassphras3”. The point is that you want to make things hard on your attacker, but still easy to remember.

When all is said and done, your best defense against hackers is vigilance. It doesn’t matter whether you use passwords, passphrases, smart cards, or biometrics. If someone really wants to gain access to your account, you have to assume they’ll be successful. Don’t believe in magic bullet solutions because they really don’t exist no matter what someone might try to tell you. Make sure you change your login information on a regular basis and keep an eye on the resources you use. Report any suspicious activities that you find. In short, don’t assume that you’re safe because you really aren’t. Let me know your thoughts about passwords, passphrases, smart cards, and biometrics at [email protected].

 

 

Cloud Computing and Privacy Rights

A number of the science fiction books on my shelf view the earth as having a single government. Countries no longer exist. Of course, we have still have countries. In fact, if anything, we have more countries today than we did thirty years ago. However, the Internet has reduced the impact of borders. The presence of global trade and other globe girdling changes have reduce the impact of borders even more. Still, countries exist partly because tradition demands it and partly because different groups have their own ideas of what a country should look like.

Most of my book shy away from any sort of legal discussion, mostly because I’m not a lawyer, but also the discussion of technology doesn’t apply to any particular country or its laws. When readers write to me, it doesn’t matter what country the reader is from, I can usually answer the question in precisely the same way. Variables work the same in Germany as they do in Spain, Japan, and America. It doesn’t mean that I’m unaware of potential legal issues surrounding technology. For example, I’ve written about privacy (or the lack thereof) a number of times.

Legal requirements, privacy needs, and the problems with borders are about to become more and more important because of one current technology and likely a host of others at some point. Storing data in the cloud means that users could create a situation where even the smallest company is in for a nasty surprise should the user work with data in other countries. Actually, the mere storage of data in the cloud could cause problems. Let’s say that the user in America chooses a storage facility in Mexico because it provides the least expensive service. Theoretically, the user’s data is subject to the laws of both Mexico (because that’s where the data is located) and America (because that’s where the user is located). If the user then travels to another country, such as Iraq, the data becomes subject (at least in theory) to the laws of Iraq as well.

In reading the views of several industry pundits on the topic, I can see where the legal issues could become quite vexing indeed—taxing even the best lawyer’s ability to untie the Gordian knot of legal consequences. So far, I can’t find anyone really trying to apply these multiple jurisdictions to a single user’s data, but I imagine it’s only a matter of time. As more and more technologies become global, however, and we begin to explore the stars with a greater sense of urgency, I begin to wonder just how long countries will continue to exist. It makes me wonder whether there will be a point at which the legal burden alone will make it a lot easier to have a single set of laws worldwide.

A number of people I’ve approached on the topic have presented perfectly valid arguments against a one world government. The most reasonable argument is that administering a single country is hard—trying to administer the entire world from a single place might well prove impossible. Still, I see more and more arguments about this whole issue of legal requirements, porous borders, global economies, and the like and it does make me wonder.

How do you feel about the legal issues regarding cloud computing? Is this simply the beginning of a much larger trend where legal requirements start to eat away at the need for countries? Does our future really involve a single world government? Let me know your thoughts on the issue at [email protected].

 

Contemplating the Future of Prosthetic Devices

I keep up with the technology used to help people live fuller lives when they have a special need in as much as is possible. Of course, even if I devoted full time to the task, keeping up with every innovation would be impossible. Still, I try to find articles and other resources that go along with some of the concepts I originally discussed as part of Accessibility for Everybody: Understanding the Section 508 Accessibility Requirements. I recently read a Smithsonian article that helped me better understand precisely where prosthetic technology will be going in the future. Hugh Herr has turned a terrible life experience into something incredibly positive by creating prosthetic devices that work more like the flesh and blood counterparts they’re designed to replace.

The technology described in the article is simply amazing. However, the article also underscores some of the underlying issues that anyone with a special need faces. People automatically think that anyone with a special need is somehow deficient or requires special treatment. Given the resources, training, and devices available today, most special needs people can live as if they don’t have a special need. In fact, as far as they’re concerned, they don’t have one. So, while the article does describe really cool technology and tells of the heroic battle fought by several people to live normal lives, it also tells of a society that just isn’t ready to understand how technology can level the playing field and what a desirable response to special needs people should be.

Which brings me back to my book. When readers write me about my book, they often miss the point. Yes, my book is designed to help developers create really cool applications. It’s also designed to help people understand their legal and moral responsibilities in helping people with special needs. A few readers even get the idea that they’re likely to require special aids at some point in their lives. However, almost everyone misses the the point that I wrote my book to help people, all people, feel acceptance for who they are—no matter who they might be or what their requirements are.

Forward thinking people like Hugh Herr really are important today because technology such as bionics have the potential to change how we view humans as a species. A recent MIT Technology Review article highlights where Dr. Herr is going and where he wants to take us. If he can realize his vision, the things we’ll be able to do boggles the imagination. More importantly, the loss of a limb will no longer be an impediment to doing anything at all. Perhaps the makers of The Six Million Dollar Man had it right all along.

Where do you think we’re going with technology designed to overcome special needs in a way that makes them all but invisible? More importantly, what do you feel are the changes society needs to make with regard to treatment of special needs people? Let me know your thoughts at [email protected].

 

Selecting a Computer Book

Readers contact me on a regular basis about selecting a computer book. I often think they want a precise recommendation from me (and some do ask me to provide a specific recommendation). However, I can’t choose a book for you or any other reader for a number of reasons. Most important of all, I don’t know how you learn. There are other issues too. For example, I can’t always guess from the e-mail precisely how you intend to use the book or what sort of information you need from it. In short, my best guess probably won’t be good enough.

Originally, I tried to handle the situation by providing a blog post entitled, “Techniques for Choosing a Technical Book.” The blog post worked well for a while, but it still doesn’t really answer reader needs. For example, readers would often act oddly if I didn’t recommend one of my own books, even though I knew from the reader query that my book would only solve part of their need and there was a better option out there. (Part of creating a book proposal is to look at the competition in depth and determine how your book will fill a niche that the competition doesn’t. I try to be honest with readers in this regard so that when they do buy a book, they’re happy with the purchase.) With this in mind, I wrote a series of three articles that examines the whole question of selecting a computer book in significantly more detail:

The goal of these three articles is to provide you with the best possible information about selecting and using a computer book. The thing I’ve noticed most often when I receive complaint e-mails is that even when a reader does select a truly usable computer book, sometimes they don’t get the most out of it. A purchase is only as good as the value you receive from it. These articles are designed to increase your satisfaction by helping you use the books more effectively.

Choosing and then using a computer book effectively will help you gain new marketable skills and insights into the computer industry. Overall, it’s my goal to help you earn more money or live a better life when I write a computer book. In other words, my goal is to help you gain something of value—something that you can later say improved your life in some way. Of course, I’m always refining my skills and choosing new techniques based on reader needs at any given time. That’s why I always want to hear from you at [email protected].

 

Self-driving Cars in the News

I remember reading about self-driving cars in science fiction novels. Science fiction has provided me with all sorts of interesting ideas to pursue as I’ve gotten older. Many things I thought would be impossible, have become reality over the years and things that I thought I’d never see five years ago, I’m seeing in reality today. People will start to look at how to sell junk car or their old car just so they can get their hands on a self-driving one, this pretty much looks like the future for us all. I discussed some of the technology behind self-driving cars in my Learning as a Human post. The article was fine as it went, but readers have taken me to task more than a few times for becoming enamored with the technology and not discussing the reality of the technology.

The fact of the matter is that self-driving cars are already here to some extent. Ford has introduced cars that can park themselves. The Ford view of cars is the one that most people can accept. It’s an anticipated next step in the evolution of driving. People tend to favor small changes in technology. Changes that are too large tend to shock them and aren’t readily accepted. People are always happy with small changes, they are more likely to buy a car if they see that it has been improved upon slightly (compared to the model that they already have). People find it so easy to buy a new car now, they don’t even need to worry about getting it either, as they can simply just get it delivered to their home by using a shipping company (you can find out more information here at this Cars Arrive Auto Relocation company). Which is great, but what’s so good about a new car that has one small change?

Google’s new self-driving car might be licensed in Nevada, but don’t plan on seeing it in your city anytime soon (unless you just happen to live in Nevada, of course). A more realistic approach to self-driving cars will probably come in the form of conveyances used in specific locations. For example, you might see self-driving cars used at theme parks and college campuses where the controlled environment will make it easier for them to navigate. More importantly, these strictly controlled situations will help people get used to the idea of seeing and using self-driven vehicles. The point is to build trust in them in a manner that people can accept.

Of course, the heart of the matter is what self-driving cars can actually provide in the way of a payback. According to a number of sources, they can actually reduce driving costs by $190 billion dollars per year in health and accident savings. That’s quite a savings. Money talks, but people have ignored monetary benefits in the past to ensure they remain independent. It will take time to discover whether the potential cost savings actually make people more inclined to use self-driving cars. My guess is that people will refuse to give up their cars unless there is something more than monetary and health benefits, as like non self-driving cars, they still need to be checked over every few years, they’re still susceptible to breaking down and needing new parts from online auto parts store TDC Automotive and others similar. So all in all, consumers won’t be jumping at the chance to buy one for the time being.

Even though no one has really talked about it much, self-driving cars have the potential to provide all sorts of other benefits. For example, because self-driving cars will obey the speed laws and run at the most efficient speeds possible in a given situation, cars will become more fuel efficient and produce less pollution. The software provided with the vehicle will probably allow the car to choose the most efficient route to a destination possible and provide the means for the car to automatically navigate around obstructions, such as accidents (which will be notably fewer). People could probably be more assured of getting to their destination on time because they won’t get lost either. Working on the way to work will allow people to spend more quality time with family. It’s the intangible benefits that will eventually make the self-driving car seem like a good way to do things.

The self-driving car is available today. It won’t be long and you’ll be able to buy one. You can already get a self-parking Ford, so the next step really isn’t that far away. The question is whether you really want to take that step. Some people may see self-driving cars as too much of a gamble, luckily we still have used car companies like Zemotor that we can buy our cars from and feeling secure about it. Let me know your thoughts on self-driving cars, their potential to save lives, reduce costs, create a cleaner environment, and make life generally more pleasant at [email protected].

Renewable Energy Inroads

I’m all for making the planet less dependent on fossil fuels, if for no other reason than they represent a finite resource. Renewable energy offers to replace the finite resources we use now with something we can harvest forever. The problem is that many renewable energy sources are really quite dirty. For example, the solar cell that adorns your roof may be killing people in China. In my opinion, we really don’t need to clean up our part of the planet by making China’s part of the planet even dirtier. In the long run, we won’t benefit by that strategy. Just think of all the really interesting poisoned toys China will send our way-toys poisoned by our own toxic waste. The toxins we generate in other countries tend to come back to haunt us.

It was with mixed feelings that I recently read that solar energy will become a major energy source within 15 years. The reasons for the increase in usage are many, but the basic reason is that solar is becoming less expensive to install and maintain.

Even if there is a possibility of solar still being relatively expensive to install, something known as the solar tax credit can ensure that people can claim a tax credit of up to 30% (depending on where you live) that can go towards the costs of your project. In many circumstances, this could persuade more people to incorporate solar energy within their homes or workplace.

There are even schools that are starting to use solar energy and other renewable energy sources now (more here). Often they do this under Act 32, which allows schools to exceed their revenue caps for energy-efficient improvements such as lighting, roofing, heating and air conditioning, energy conservation. Plus, now it’s easier than ever to contact a solar battery supplier and look into purchasing some solar batteries. Not only this but the costs of the solar panels and their installation has gone down considerably, so it’s possible that solar power might actually become less expensive than using fossil fuels at some point. Of course, the savings assume that you’re not storing excess power in batteries. Adding batteries to the picture greatly increases costs and makes solar quite expensive indeed.

There is one benefit to solar energy that many people don’t think about. If the solar panels appear on people’s rooftops in a decentralized configuration, the ability of terrorists to disrupt the electrical system is greatly diminished. A decentralized setup also reduces costs associated with power transmission and could actually do things like reduce cooling costs in summer. Of course, the utilities aren’t crazy about decentralized solar because it cuts into their profits, but the fact of the matter is that we need a better setup than the one we do now. Our system is so fragile right now that I’m often surprised a storm or other simply cause doesn’t knock out major sections of the country.

The bottom line for me is that we really do need to reduce our power usage and embrace renewable energy sources. However, we need non-polluting renewable energy sources or at least sources that pollute less than the ones we have now. I last tackled this topic in More People Noticing that Green Technology Really Isn’t. The fact is, nothing has changed in the technology, but the need to address the technology shortfalls has just become greater. Before a technology that pollutes our planet quite a lot becomes entrenched, we need to come up with answers to deal with the pollution-preferably a better technology.

What are your thoughts on renewable energy? What forms do you feel pollute the least and provide the greatest benefit to people as a whole? Do you see renewable energy becoming the only power source at some point? Let me know your thoughts on these and other energy concerns at [email protected].

Review of Mastering VBA

A lot of people have asked about the next book to read after reading VBA for Dummies. Yes, the current 5th edition of VBA for Dummies still works fine as a starting point, even with issues such as dealing with the Ribbon to consider. In fact, you can find some great updates to VBA for Dummies on my blog. However, the fact of the matter is that readers have been asking for more, which is where Mastering VBA by Richard Mansfield comes into play. This is the next book you should get if you want to move on from what VBA for Dummies shows you to writing applications with greater functionality. For example, a lot of you have requested more information about creating forms and Chapters 13 through 15 will help you in this regard. Richard has done an outstanding job of moving you to the next step of creating the complex forms required for robust applications.

Another common request that Mastering VBA addresses is the need for security. While VBA for Dummies helps you understand the need for basic security, Mastering VBA takes the process several steps further and could help prevent breaches given the modern computing environment (one that didn’t exist when I wrote VBA for Dummies). Chapter 18 begins the process by emphasizing the need to build well-behaved code. After all, if your code doesn’t behave, there isn’t any set of security measures that will protect it from harm. Chapter 19 goes on to help you understand the essentials of good security, especially with all the modern threats that cause problems for developers today.

At 924 pages (versus 412 for VBA for Dummies), Richard is also able cover some topics in detail that would have been nice to have in my own book. Readers have complained about having to go online to view object model details for the various Office applications in my book. Mastering VBA provides coverage of the object model as part of the book so you can work through it without having to go anywhere else. It’s a convenience issue—readers really shouldn’t have to look for essentials like the object model online, but every author has to face space limitations when putting a book together. The object model material is spread out across the book, but there really isn’t any way to organize it so that it all appears together. This is one time when you’ll need to actually use the table of contents and index to find the material you need.

As with all the books in the Mastering series, this one has questions at the end of each chapter. These questions are designed to help you master the skills learned in the chapter. You find the answers for each of the questions in the back of the book. This makes Mastering VBA an excellent option for the classroom. More importantly, it gives you another way to learn the material in the book. The longer I write books, the more I come to realize that one or two methods of learning simply won’t do the job. This book usually provides three or four ways to learn each task, which means that you have a higher probability of actually mastering the material (as defined by the title).

For all of you who have been asking for the next book after VBA for Dummies, Mastering VBA is the one that gets my recommendation. Until I actually have time to write a book that specifically addresses the concerns in the reader e-mails I’ve received, this book is your best option. No, it doesn’t address every e-mail request that I’ve received, especially with regard to form creation, but it does answer a considerable number of them. Of course, I’ll look forward to your continued interest in my book and I hope you keep those e-mails coming my way!

 

Fighting Dry House Conditions

Anyone who knows me, knows I love my wood stove. It keeps my house toasty warm. The floors, walls, and ceilings are all warmed so that I can walk around barefoot in my 68 degree house if I want. Just try doing that in a house heated by a furnace! So, there is no doubt that I’ll continue to enjoy the benefits that radiant heat can provide.

There are down sides to everything and heating a house tends to produce really dry air. My furnace has an Aprilaire whole house humidifier attached to it. On those rare occasions that I do use the furnace, my Aprilaire adds much needed humidity to my really dry house. Of course, not everyone has such a device, so houses heated with furnaces can suffer from a lack of humidity too. Fortunately for us, a HVAC can give us the help we need to do deal with a humid home. A friend of mine had this issue and found that a local service similar to Complete Comfort Plumbing Heating & Air (completecomfort-hvac.com/areas-we-serve/aliso-viejo-ca/) could help him install a system into his home which dealt with the humidity.

Horridly dry air has a number of nasty side effects. For example, you might find that you literally can’t breath because your nose is so dry. Petting the cat becomes an experiment in shock therapy (and don’t even think about brushing the dog). You could see damage to your furniture as well. The glue joints tend to fail when the humidity is too low. So, there are both health and monetary issues to consider when it comes to winter heating. The issue that seems to elude most people though is that humid air is able to support more calories than dry air. This means that really dry air actually feels cooler than humid air heated to the same temperature. Humidity that causes you to sweat in summer keeps you warm in winter, so having a good HVAC system could not only regulate the air in your home but help to keep your family warm in the winter and cool in the summer. You can Read more here.

Over the years I’ve come to believe that keeping a house as humid as possible in the winter (within reason, you really don’t want the walls dripping either) is a good idea. But when it comes to the summer months, some people can’t think of anything worse than having a humid home. Who could blame them? You would literally be sweating all of the time. That’s when places similar to this Air Conditioning Repair Houston company come in useful. If your life-saving air conditioning system malfunctions, you won’t be receiving that cold air that helps to cool you down, so what happens? You’ll feel even hotter. If that happens, (just like it did to my friend last week), you should get it fixed as soon as possible. For me though, I welcome the feeling of humidity, especially in the winter months. When my hygrometer (a humidity measuring device) reports 60 percent, I’m quite happy. Even 50 percent is worthwhile achieving. The problem is that with wood heat, you don’t have an Aprilaire to help out.

Assuming that your wood stove provides a place to put one, the first course of action is to get a couple of inexpensive soup pots-big ones. Actually, you might be able to get one almost free at a thrift store or garage sale, so look around to see what you can find. Fill them with water and put them on the wood stove. The heat will evaporate the water inside and produce humidity for your home. If you want, you can add wood stove simmering spices to make you home smell nice as the water evaporates. The people living with you in your closed up house will appreciate the fragrance. My stove will accommodate two pots, so I have two really large pots going most of the time (one is removed when I want to heat water for tea, heat something up, or make soup).

Sometimes using the pots just doesn’t help enough, unfortunately. It’s during those times that I leave the bathroom door open when I shower and turn off the ceiling fan. The ceiling fan normally takes the humidity outside, which is a really good thing to do in summer when you don’t want things rotting inside the house. During the winter, it seems like a better idea to allow the steam to get out into the house. Of course, you’ll need to exercise more caution to ensure everyone keeps their privacy intact. We actually have a few Ceiling Fans in our home. I think that they are such classic pieces that never go out of style. Plus, they help to control the temperature in your rooms so they are incredibly useful.

Winter is also a dandy time to make soup. It’s possible for me to make soup on my wood stove when it’s completely fired up. However, there are a lot of times where I still need to use the stove. In those cases, I keep the stove’s vent fan off so that the steam from the soup stays in the house. Not only does the house get humidified, but it also helps build a healthy appetite.

I’m sure by now someone is wondering why I haven’t mentioned the obvious-a humidifier. Yes, a humidifier will do the job and yes you could use one, but all of the other techniques I’ve mentioned are free. A humidifier will cost money to purchase, maintain, and operate. In the long run, using every free technique at your disposal first is the best idea. Let me know your ideas on humidifying a home at [email protected].

All Cooped Up

I normally let my chickens run free during the entire year. They get outside and play games outside while pecking around for things to eat. They really are quite funny at times. One of their favorite winter games is Queen of the Hill. I put a french fry or other treat on top of a snow hill and the chickens race to see how gets it first. The chickens knock each other off the hill and grab the french fry until it’s gone. Of course, the game continues as long as I have french fries to offer them. The outside time is important because it allows the chickens to exercise properly and to gain access to alternative food sources, such as bugs. In addition, getting out of the coop provides them with fresh air and time to interact with their environment.

After seeing my egg production (and subsequent sales) drop to nearly nothing this past winter, I decided to try something out. On truly cold days, I’ve been keeping the chickens in the coop. I’m not talking about a coop with the door open, but with the door closed so that the coop stays significantly warmer. On the coldest days, I’ve been putting a pot of hot water in the coop to partially heat it. As a result of this change, my chickens are laying more eggs—a lot more eggs. In fact, egg production has increased threefold over egg production last winter at this time. Mind you, I’m getting this increase without disturbing the chicken’s natural light cycle by using a heat lamp or other light source.

The results seem consistent. In addition, the only thing I’ve changed is the time the chickens spend in their coop. I did note that there is no increase after a certain point. Keeping the chickens in their coop six days a week didn’t provide an appreciable increase in production over four days. What seems to be the most important factor is choosing days that are especially cold. Right now I’m keeping the chickens in their coop when the temperature falls below 20. However, I plan to keep playing with the temperature to see what effects I can come up with. The chickens might actually do better if I keep them in the coop anytime it’s below freezing, but something tells me that they’ll begin fighting if I do.

What I’m trying to figure out now is how cold is too cold for the chickens. They survive just fine, even if I let them out in relatively cold weather. The thing that changes is the number of eggs they lay. The cold stresses the chickens just enough to stop laying almost completely. I’m still experimenting to find the trigger temperature for this effect. Figuring out the correct temperature is important because the chickens really do need the outside time to remain healthy.

Like many topics related to chickens, trying to find specific temperature guidelines online has proven impossible. However, there must be others who have experimented in figuring out just the right temperatures for letting chickens go outside to play. Let me know your thoughts on the topic at [email protected].

 

Considering Our Future Cyber War

It’s not if a cyber war will happen, but when. Precisely what form such a war will take depends on the perpetrators and their goals. I’ve spend quite of time discussing the relative insecurity of the Supervisory Control and Data Acquisition (SCADA) systems out there. However, I’m only assuming that SCADA is going to be targeted at some point because it’s such low hanging fruit and no one seems to have any interest at all in securing. Plus, the attack would be of the sort that we’d have a hard time defending against (and possibly identifying at first as the hospitals fill with victims of some mysterious problem).

I recently read an article by John Dvorak entitled, “What if Facebook Is Hacked Next?” John makes some excellent points, but probably doesn’t go far enough. Why would an attacker stop with just Facebook? Why not attack all of the sources of social media out there, including places like LinkedIn and Twitter? The confusion created by the loss of all social media would be amazing. It could easily act as a smokescreen for some other activity even more devastating than the loss of data. While everyone is scrambling to fix their social media issues, someone could work in the background to do something truly horrible.

Actually, the attacker might not even have to do anything other than disrupt all online activities. Think about the number of jobs lost, the hit to online commerce, and the other problems that such an attack would cause. Perhaps these people are simply waiting until more brick and mortar stores close that people no longer have local resources to help in such an emergency. For example, think about the problems that the loss of online stores would have to IT professionals who maintain huge networks of computer systems. The potential for truly terrifying results is amazing.

A cyber war is coming. Just when it will arrive is the topic of much speculation, but my feeling is that it’ll come sometime soon. What sorts of security measures do you have in place? Have you done anything else to prepare? Let me know about your thoughts on cyber war at [email protected].
