A safer internet isn’t a nice thing to have. It’s a necessity because we rely on it so heavily. And there’s plenty we can do to make it happen.
A safer internet might seem like it’s a bit out of our hands as individuals. The truth is that each of us plays a major role in making it so. As members, contributors, and participants who hop on the internet daily, our actions can make the internet a safer place.
So, specifically, what can we do? Take a few moments to ponder the questions that follow. Using them can help frame your thinking about internet safety and how you can make yourself, and others, safer.
Device safety is relatively straightforward provided you take the steps to ensure it. You can protect your things with comprehensive online protection like our McAfee+ plans, you can update your devices and apps, and you can use strong, unique passwords with the help of a password manager.
Put another way, internet safety is another way to keep your house in shape. Just as you mow your lawn, swap out the batteries in your smoke alarm, or change the filters in your heating system, much goes the same for the way you should look after computers, tablets, phones, and connected devices in your home. They need your regular care and maintenance as well. Again, good security software can handle so much of this automatically or with relatively easy effort on your part.
If you’re wondering where to start with looking after the security of your devices, check out our article on how to become an IT pro in your home. It makes the process easy by breaking down the basics into steps that build your confidence along the way.
This includes all kinds of topics. The range covers identity theft, protecting your personal info, privacy, cyberbullying, screen time, when to get a smartphone for your child, and learning how to spot scams online. Just to name a few. And if you visit our blogs from time to time, you see that we cover those and other topics in detail. It offers a solid resource any time you have questions.
Certainly, you have tools that can give you a big hand with those concerns. That includes virtual private networks (VPNs) that encrypt your personal info, built-in browser advisors that help you search and surf safely, plus scam protection that lets you know when sketchy links pop up in emails and messages.
However, internet safety goes beyond devices. It’s a mindset. As with driving a car, so much of our online safety relies on our behaviors and good judgment. For example, one piece of research found that ninety-one percent of all cyberattacks start with phishing emails.i
As Tomas Holt, professor of criminal justice at Michigan State University, states, “An individual’s characteristics are critical in studying how cybercrime perseveres, particularly the person’s impulsiveness and the activities that they engage in while online that have the greatest impact on their risk.”
Put another way, scammers bank on an itchy clicker-finger — where a quick click opens the door for an attack. Educating your family about the risks out there, such as phishing attacks and sketchy links that crop up in search goes a long way to keep everyone out of trouble. In combination with online protection software like ours covers the rest of the way.
A big part of a safer internet is us. Specifically, how we treat each other — and how we project ourselves to friends, family, and the wider internet. With so much of our communication happening online through the written word or posted pictures, all of it creates a climate around each of us. It can take on an uplifting air or mire you in a cloud of negativity. What’s more, it’s largely out there for all to see. Especially on social media.
Take time to pause and reflect on your climate. A good place to start is with basic etiquette. Verywell Family put together an article on internet etiquette for kids, yet when you give it a close read, you’ll see that it provides good advice for everyone.ii
In summary, their advice focuses on five key points:
Of course, the flip side to all of this is what to do when someone targets you with their bad behavior. Such as when an online troll who hurls hurtful or malicious comments your way. That’s a topic in itself. Check out our article on internet trolls and how to handle them. Once again, the advice there is great for everyone in the family.
We’ve shared quite a bit of info in this article and loaded it up with plenty of helpful links too. Don’t feel like you have to take care of everything in one sitting. See what you have in place and make notes about where you’d like to make improvements. Then, start working down the list. A few minutes each week dedicated to your security can greatly increase your security, safety, and savvy.

What’s blockchain technology? The term gets bandied about often enough, but it doesn’t always get the explanation it deserves.
Understanding the basics of blockchain can help you understand several of the big changes that are taking place online. It’s the foundational technology that underpins cryptocurrency and NFTs (non-fungible tokens), yet it has several other emerging applications as well.
In all, gaining a sense of how blockchain technology works will give you a further sense as to how it may eventually shape the way you go about your day.
Blockchain technology holds great potential because of the unique, decentralized way it handles data—which marks the first step in understanding how it works.
An easy way to visualize how a blockchain works is with an old-fashioned ledger. Each ledger entry is a link in a “chain.” Within each chain is a unique identifier known as a hash and a block of data associated with it. Over time, chains get added, which updates the hash as new blocks of data are added to the chain.
A simplified example of a blockchain storing recipe instructions. The Previous Hash and Stuff (data) fields generate the Hash field. This Hash becomes part of the next record.
Yet one of the most important aspects of blockchain technology is this—it’s decentralized. Dozens, hundreds, thousands, or more participants in the blockchain track and validate the transactions associated with it.
Each blockchain entry gets validated through consensus, where individual participants on a blockchain network must all “agree” that the data in each entry is correct. Participants in the blockchain network can arrive at consensus through several models, yet commonly they use cryptographic calculations to validate an update to the chain.
In this way, blockchain technology removes the need for a central authority to oversee a transaction, such as a bank. Put simply, blockchain gets rid of the go-between. And it makes transactions more anonymous as a result.
Participants in a blockchain network receive a small amount of cryptocurrency per transaction as a reward for their efforts. Enter the notion of crypto mining, where some miners set up large-scale farms of powerful, specialized computers that participate in blockchain networks.
Blockchains come in public and private forms. Public is just as it sounds, where anyone can participate in the blockchain. They can read, write, or validate data in the blockchain. Private blockchains are invite-only in nature and can establish rules about who can alter the blockchain.
Many blockchain ledger entries record financial transactions associated with cryptocurrency. However, ledger entries can contain any type of data. One can just as easily store documents, images, log files, or other items in a blockchain. Even decentralized programs, also known as smart contracts, can be stored.
In all, there’s much more to blockchain technology than just cryptocurrency.
First and foremost, blockchain technology is at the heart of cryptocurrency. Wherever cryptocurrency is bought, spent, or exchanged, the blockchain is there to facilitate the transaction. However, we can point to several new and emerging applications as well, including:
Blockchain technology offers several benefits, yet it has its downsides as well.
Decentralization removes the need for third parties in transactions because the blockchain provides the verification and oversight for the transaction to go through. In the case of financial transactions, that removes the need for banks. In the sale of property, that removes the need for a title company.
However, if there is a conflict or issue between the parties, they have no central authority to manage its resolution. (See this story written by a BBC journalist about his quest to recover stolen crypto funds.)
Additionally, decentralization can afford parties anonymity, which can cover up illegal activities—thus making cryptocurrency is the coin of the realm for scammers and murky marketplaces on the dark web.
Blockchain technology is open, meaning that theoretically anyone with a specially equipped device can generate revenue as a miner in the blockchain economy. Yet the reality is that much of the technology is in the hands of the few. For starters, these mining devices are expensive. Secondly, it takes hundreds of these devices to mine effectively, which points to the advent of the industrial-sized mining farms mentioned above.
To put it all into perspective, one study estimated that “(t)he top 10% of [Bitcoin] miners control 90% and just 0.1% (about 50 miners) control close to 50% of mining capacity.”
Additionally, all that computing power comes at an additional cost—energy. It takes electricity to run those huge mining farms, and it takes yet more electricity to keep them cool. As a result, crypto mining can generate an outsized carbon footprint if the electricity is generated with fossil fuels.

Of note, the second-largest cryptocurrency, Ethereum has made great strides on the energy consumption front. It updated the way the cryptocurrency arrives at consensus in its blockchain and uses far less energy as a result. Estimates show that Ethereum’s carbon footprint decreased by about 99.992% from 11,016,000 to 870 metric tons of CO2.
As far as technology goes, we still live in the relatively early days of blockchain. And while much of its popular focus revolves around its role in cryptocurrencies like Bitcoin, the technology offers more than that. Of course, it remains to be seen which of its applications will take root.
Blockchain has its own barriers, though, particularly when it comes to security. Like any other connected technology, it finds itself the target of hacks and attacks. Billions of dollars in cryptocurrency have been stolen from individual users and exchanges over the years.
The security issue isn’t necessarily with the blockchain itself. That’s highly difficult to hack thanks to encryption and the decentralized nature of the blockchain. Instead, the networks they are on are subject to attack—such as interception attacks where bad actors extract information or cryptocurrency. Other attacks involve flooding the blockchain network with false identities that ultimately crash the system. And yet more exploit weaknesses in the security protocols used by platforms like cryptocurrency exchanges.
Then there’s the tried-and-true phishing attack, where scammers dupe victims into handing over their personal encryption keys. With a key, the scammer can empty digital wallets of their cryptocurrency or compromise a private blockchain network and that data in it.
Clearly, the future remains speculative as people and organizations explore the uses of blockchain technology. Without question, security will play a major role in its adoption.
Unless you’re dabbling in cryptocurrency yourself, blockchain will likely remain a behind-the-scenes technology. At least for the time being.
Yet it can still shape your day in some way. It might help bring fresher produce to your market. It might secure smart utilities and smart infrastructure in your city. And it might give your auto manufacturer a powerful tool for identifying and recalling a faulty part in your car.
Although barriers of security, energy consumption, and equity remain, it stands a good chance that blockchain technology will continue to change our lives. And understanding how it works can help you better understand those changes.

Read this statement, then read it again: Just five distracted seconds at 55 mph is equivalent to driving the length of a football field with your eyes closed. This alarming truth from the National Highway Traffic Safety Administration (NHTSA), highlights the need for parents to address the issue of distracted driving with their teens.
Additional distracted driving statistics are mind-blowing. According to the NHSTA, 77 percent of drivers admitted to using their phones while driving, 74 percent used their map app, 56 percent read emails or texts, 27 percent updated or checked their social media accounts, and shockingly, 19 percent of drivers—equivalent to one in five—engaged in online shopping while driving.
In the United States, distracted driving has become a leading cause of fatal crashes, accounting for 25 to 30 percent of all fatal crashes. Furthermore, overall highway fatalities have increased by 22 percent, as reported recently by The Los Angeles Times, which attributed this rise to the allure of technology turning our cars into “candy stores of distraction.”
While technology plays a significant role in distracted driving, other everyday choices and factors can also contribute to accidents. Eating while driving, managing a lively pet in the car, navigating unfamiliar streets, and even talking with peer passengers can distract young drivers. Studies have shown that crash risk doubles when teens drive with one peer passenger and quadruples with three or more teen passengers.
In the throes of summer, it’s a great time for parents to have a conversation with their teen drivers about the dangers of distracted driving and texting while driving. Here are some important topics to discuss and tips to help keep your kids safe on the road:
Remember, developing good (or better) habits takes time, effort, consistency, and parental involvement in teen driving. Preventing distracted driving with positive behavior change won’t happen overnight. Repeat yourself when it comes to road safety without apologies. Giving your child rules and expectations demonstrates love. By making some of these shifts, hopefully, you will worry less, raise wiser drivers, and improve safety for everyone on the roads.
