Why Your Windows Updates Are More Important Than Ever

Stories about hackers and virus attacks seem to be making the news almost every day, and many of these news stories include tips on how you can avoid becoming a victim. One common theme among these tips is making sure your Windows operating system up to date.

Every day hackers are trying to figure out new ways to break into Microsoft Windows and once they do find a weakness, they try and find a way to spread it. This could be through a malicious email attachment or even something that spreads without your involvement.

Updates Explained

Whenever Microsoft discovers a potential flaw, they push out a small piece of software to all Windows computers running a supported version. If set correctly, your computer will check if there’s any updates or patches and install them automatically. In new versions, this usually happens when you’re shutting down or starting up, and doesn’t impact your experience at all. Unfortunately, some users will manually disable or delay their updates, creating a risky situation.

The update may include security patches, drivers or a simple tweak to address bugs or issues with Windows. Sometimes, they even include new features or applications to improve the stability of your operating system. They’re a good thing!

Not All Versions Get Updates

Some older operating systems are no longer supported, which means unless there are extenuating circumstances, Microsoft won’t issue any new updates. Not a single one – generally, if cyber criminals discover a flaw after support ends, they’re free to exploit it. For example, Windows XP support ended in 2014, and Windows Vista just ended in April this year. The moment an operating system is retired it becomes a playground for cyber-criminals.

It’s not just Microsoft walking away from these old versions either. Third party software like the Google Chrome browser will still work, but they’ve also stopped supporting old versions with crucial updates and patches. It might seem like everything is working fine because your anti-virus isn’t pinging in alarm, but it just becomes a case of risk, upon risk, upon risk.

What to do with older Windows

As much as you’re comfortable with your older version of Windows, each time you boot up you’re exposing your system, important files and entire network. It only takes one weak entry point in the chain to allow malware into all connected devices. That could mean your photo storage, media center or even smart appliances. It’s not worth it – if you’re running Windows XP or Vista (or older), you need to update to a more modern operating system ASAP. Give us a call to upgrade your computer.

We can also monitor your system remotely and apply your Windows updates with our Managed Services packages, ensuring you are always up to date and protected. Give us a call at (416) 645-2469, (905) 667-0441 or email us at info@cpinetworks.ca.

How Much Could A Ransomware Attack Cost You?

Have you ever thought about how much your data is worth? Information is possibly the most valuable part of your business – there’s your client database, accounting software and inventory management, and of course, any intellectual property you may own. When the ransomware, WannaCry, tore through the world recently, many businesses were suddenly forced to re-assess the value of their data: was it worth saving, and what would be the deeper cost of the attack?

Most ransomware attacks cost $150-$600 to get your files released, but that’s only IF the cyber-criminals honor the payment and actually give you the decryption key. Meanwhile, new client calls are still coming in and you may find yourself unable to operate with your systems down. Paying the ransom or restoring from an unaffected backup seems like a quick fix, but it doesn’t end there. There’s still the downtime involved to restore all your data – possibly days – and that’s a lot of lost productivity. Plus, if word gets out that your data has been compromised, you may find confidence in your business plummets and your existing clients head elsewhere. That $150 ransom may end up costing well over $150,000!

Prevent Ransomware Attacks on your Business

Keep your systems up to date: WannaCry took advantage of a flaw in older versions of Windows, one that was since patched by Microsoft. But to be protected, businesses had to be up to date with their patches AND be running a supported version of Windows. Delaying patches and updates puts your business at risk – we can help you update automatically.

Lock down employee computers: Very few staff will require full administrator access to your business network. The higher their level of permissions, the more damage a person can do – either accidentally with a whoopsie click, or by inadvertently installing malware. By locking down your employee computers, you have a better chance of containing a malware attack to non-vital systems. Our experts can design an access management plan that gives you best of both worlds: flexibility PLUS security.

Educate your workplace: Most employees believe they’re being cyber-safe but the reality is quite different. Many malicious links and embedded malware have become hard to spot in an instant – which is all it takes to click and regret. We can work with your staff to establish procedures around checking links for authenticity before clicking, awareness around verifying the source of attachments, and the importance of anti-virus scanning. We’ll help get the message through!

Have a solid backup plan: When ransomware hits, a connected backup = infected backup. Unfortunately, synced options such as Dropbox immediately clone the infected files, rendering them useless. The only safe backups will be the ones both physically and electronically disconnected, with systems designed to protect against attacks like this. Our experts can set you up with a backup system that makes recovery a breeze.

Be proactive: The best way to avoid the financial cost of a ransomware attack is to prevent it from happening in the first place. Remember, many businesses were able to watch WannaCry from the sidelines, completely unaffected and seizing opportunities while their competitors were down.

Our managed services can help protect your business against the next cyber-attack.

4 Important Reasons to Use Anti-Spam Filtering in your Business

Remember when spam was obvious, and unless you desperately needed a special blue pill, it was easy to identify and ignore? Those were the days! The impact on your business would have been minimal, as spam was more an annoyance than anything else. Unfortunately, spam has matured into an aggressive threat, marked by sophisticated attacks and rapidly evolving techniques. It’s not just random electronic junk mail anymore and it’s putting a costly strain on your business resources.

How Spam Impacts Your Business

Spam now contains malware, with hackers sending cleverly disguised emails to your business. Once clicked by an employee, it infects your computer system (virus) or steals your private data (phishing). The malware can then spread across the entire computer network and beyond, including to your clients and vendors. The very fact that your employees must pause and examine every single link and attachment adds hours of lost productivity. Occasionally, spam is so convincing that only an expert would be able to visually identify it. Employees are also more likely to miss an important email, either not seeing it arrive at the same time as a spam attack or becoming overwhelmed with the sheer number of emails.

How Anti-Spam Can Save Your Business

1. Block threats: The spam filter’s purpose is to block the spam from ever reaching your employees’ screens. The threat is automatically identified and either held securely or immediately deleted. This is the best way to avoid activating spam malware, as it’s so easy to click through links in an email that seems authentic and important. The effects of that one spam click may be instantaneous or may lie hidden for months. Removing the email before it becomes a risk is a much better option.

2. Filter legitimate emails: Real mail needs to be able to stand out and avoid the trash. Anti-spam filtering has sophisticated recognition abilities which block spam only and allow real mail to land safely in mailboxes.

3. Meet data regulations: Many businesses are subject to strict privacy and data storage regulations, some more so than others. To continue operation, they have to meet conditions including always using spam filtering to reduce the risk of data breach.

4. Protect your business reputation: You can see how uncomfortable CEOs are when they hold press conferences to admit a breach. They must acknowledge that they failed to protect client data, or that users may be infected with a virus. Not only do they then face financial loss, their business reputation takes a nosedive. Anti-spam filtering can ensure these types of scenarios don’t happen to you.
Filtering has come a long way in recent years, with complex algorithms identifying and catching spam before it becomes a risk to your business. Real emails can now pass safely through without the classic catchcry of ‘check the spam folder’, and businesses can work with greater productivity and safety than ever before. You need email, but you definitely don’t need spam or the chaos it brings to your business.

We can block spam and keep your legitimate emails flowing by using our Canadian Hosted Exchange email services. Call us at (416) 645-2469, (905) 667-0441 or email us today!

How Many Good Battery Habits Do You Really Have?

Batteries are rarely talked about – until they’re drained – then we’ll tell everyone as we beg desperately for a charger, hoping to get enough juice to last the day. The truth is, they’re a miracle of engineering that gets taken for granted when full and cursed when flat. If it feels like your battery is running out faster, you might be right.

But it’s not because of ‘battery memory’ and needing to be cycled (that’s an older battery type called NiMh), it’s because the modern LITHIUM-ION batteries in phones and laptops just simply wear out over time. Fortunately, extending your battery life is easier than you think! Which of the following GOOD battery habits do you have?

Charge whenever you can: Lithium-ion batteries don’t like being charged all the way up and then drained all the way down. No wonder, it even sounds exhausting. Give them a little charge here and there, and they’ll be happy.
Leave your laptop plugged in all the time: You can’t over-charge the battery, it will just sit there waiting to be used. The laptop also helps out by cutting the flow of power when the battery registers as fully charged.
Watch for overheating: If you can, remove your laptop battery while charging, because while it won’t overcharge, it may overheat. You might also consider removing the battery if you’re using your laptop plugged in all the time. Sure, you might lose data if there’s a power outage, but overheating is a far more common occurrence and it’s been proven to degrade battery life considerably. Check your vents are clear with good airflow, and if necessary, help it out with a cooling laptop stand.
Leave your phone plugged in all night: Just like your laptop, your charger knows to stop when the battery is full. Those chargers do generate heat though, so make sure you have enough airflow around both charger and phone, and never sleep with it under your pillow.
Charge batteries before storing: If you’re blessed with backup batteries, make sure to give them a half charge before storing. They’ll naturally discharge and age over time, so this gives them a fighting chance to still be viable when you need them.
Keep your cool: We know to avoid water with our phones, but we’re less careful about exposing it to heat. This includes leaving it in your car all day, placing it on top of your PC, or even in a sunny spot by the window. Wireless and rapid chargers can also be an issue, as the amount of heat they generate will affect your battery.

How did you go? Is keeping your lithium-ion battery happy easier than you thought? Your battery will wear out over time, but you can push that day a few years into the future if you remember to keep it charged and keep it cool.

Cyber Security: 4 Ways to Travel Safe For Business

Working from anywhere is now as simple as accessing the internet on your device. Managers, owners, and employees are all embracing the flexibility of working while traveling, making it the new global norm. But while you were in the office, you were protected by professionally designed firewalls, security infrastructure, and robust software. As soon as you step away from the building, those protections disappear, leaving your device and the data inside at great risk.

Cyber attackers love to collect any data they can obtain, often preferring to hack first, assess value later. It doesn’t help that almost all data can be sold, including your personal details, those of your clients and suppliers, as well as your proprietary business data. These days, the information stored on your device is usually worth much more than the device itself.

Here are 3 ways a hacker will attack:

Flaunting Opportunity: Whether your employee left their laptop at a café or a thief stole the phone from their pocket, the outcome is the same – that device is gone. Hackers will take advantage of any opportunity to gain access to a device, including taking them from hotel rooms and even asking to ‘borrow’ them for a few minutes to install spyware, before handing it back.

Spoofing a Wi-Fi Hotspot: We’ve all come to expect free Wi-Fi networks wherever we go. Hackers will take advantage of this trust to create their own free, unsecure network, just waiting for a traveler to check a quick email.

Intercepting an Unsecure Network: Hackers don’t need to own the Wi-Fi network to steal content from it. Data traveling across an unsecure network is visible and available to anyone with the right software.

It’s okay, you don’t need to lock all employees inside the building or cancel all travel plans. Taking these four precautions will increase cyber safety and help protect your business data while on the go.

Make a backup before you travel: In the event your device is lost or damaged, you’ll be able to replace the device with a new one and quickly restore all the data from a backup, all with minimal downtime.
Don’t use public Wi-Fi: Wait until you have access to a secure network before going online – even just to check email.
Use passwords and encryption: At a minimum, make sure you have a password on your device, or even better, have full drive encryption. That way, even if your data storage is removed from the device, the contents are inaccessible.
Act fast after loss: If your device is lost or stolen, immediately notify the appropriate people. This might include your IT provider so they can change passwords, your bank so they can lock down accounts, and any staff who need to be aware of the breach so they aren’t tricked into allowing further breaches.

Welcome to the ‘Internet of Things’

You arrive at home and the door unlocks because it knows who you are, sensing the key in your pocket. The lights switch themselves on and your favorite music begins to stream gently through the living area. It’s already the perfect temperature, and as you head for the fridge, you notice an alert on the screen congratulating you on meeting your exercise goal today and suggesting a tasty snack.

Okay, it sounds like a scene from a movie, but it’s actually reality today thanks to the Internet of Things (IoT). Almost anything that can be turned on or off is now able to be connected to the internet. An entire industry has popped up to help users create a custom experience designed around their unique needs. Electronic locks, lights, healthcare wearables and household appliances are just the beginning. IoT goes beyond devices you can use to surf the web – it’s a global revolution.

Adapters can transform even the most random appliance into a connected gadget, as well as add new layers of functionality. Cloud software is creating piggy-back connections, resulting in not just a new experience, but a new way of interacting with the data produced. It may all seem impossibly futuristic, but IoT is less about technology and more about enhancing relationships between people-people, people-things and things-things.

Millions of people are wearing a Fitbit or Jawbone to track steps and calories, while others are letting their fridge order groceries! The practical applications are almost endless, commonly including: GPS trackers on pets, home security via webcam, patient monitoring of blood pressure/heart rate, weather monitoring, and remote power points. No more worrying all day if you left the iron on, just push a button on your phone and know for sure it’s turned off.

Of course, with all this connectivity comes risks. While the idea of having your toaster hacked is a bit mind-boggling, technology connected to the internet is open to exploitation. The webcam that allows you to monitor your pets may also allow other people to glimpse inside your home, but only if it’s not secured properly. Unfortunately, it only takes one small gap for a cyber-attack to get through, and once in, all connected devices are at risk.

Having your lights taken over by a far-away prankster may seem like a small risk, but gaps allow them into your computers, phones and tablets too. That’s the part the movies skip over – the networking protections that exist in the background, shielding against attacks.

Taking the time to properly secure your IoT device is essential to making sure you get the whole, happy future-tech experience. We’re big fans of IoT and can’t wait to see what comes next!

Got an IoT device? Give us a call at (416) 645-2469, (905) 667-0441 or email us to help you set it up securely.

ALERT: Your Antivirus May Be Letting You Down

The best way to avoid a computer virus is by using common sense, but that doesn’t mean you’ll be safe from attack. Even the most careful user can find themselves infected in an instant and spreading the virus faster than a sneeze in flu season. It’s why antivirus software is still the first package we install on all systems – because you never know when you’ll be attacked. But should you choose free or paid antivirus?

Advertising: Much like a free app making its fortune with in-app purchases, the free antivirus software will push for payment. Expect popup boxes pestering you to sign up to the paid version at least daily. Some free options will also try to change your browser home page and default search engine, an inconvenience you may be stuck with. Paid options are more respectful and largely invisible unless they’ve detected a problem.

Effectiveness: It’s fair to expect your antivirus to detect malware, and testing showed that in a head-to-head battle free and paid are about equal at catching known infections. And therein lies the kicker: generally speaking, free antivirus needs to have recorded a virus to its library before it can detect it. Paid antivirus is more likely to identify and stop a new virus. It essentially bases the detection on suspicious behavior, source and attributes, a far more effective method of detection.

Features: Free antivirus options are usually created from the paid version, taking out everything except the bare minimum. In your paid version, you can expect advanced features like spam filters, firewalls, parental controls and secure web browsing. Some paid antivirus will also update your other software packages, forming a more secure protection against attacks. For example, you might view a malicious image file that takes advantage of an exploit in your PDF software. Unfortunately, hackers have advanced beyond simple tactics and it’s not just about avoiding email attachments anymore.

Support: Free antivirus options are the most popular choice because they’re… free. Obviously. This also means there’s generally no support available. If there’s a problem or conflict with another program, you may find yourself without protection until it can be resolved. Paid antivirus options usually include telephone support, ready to help with problems ranging from installation to system diagnostics.

Ease of use: Depending on what you use your computer for, this may be an important concern. Free antivirus options are easy to install and use, but are very limited in their flexibility. They come as-is, meaning you can’t pick and choose what it monitors or how it reacts. For example, users occasionally find it necessary to disable ALL protections in order to install a network game. Paid versions are more likely to allow you to adapt the way it runs, switching features on and off as required.

Free antivirus is fine for very basic protection, those on a budget or those with an older PC. In these cases, something is always better than nothing. But we generally recommend you go with a paid antivirus to defend you from the new attacks that are released daily, and to ensure you’ve got solid protection that will make a real difference to your digital safety.

Talk to us (416) 645-2469, (905) 667-0441 or email us about upgrading to a paid antivirus or even better a Managed Antivirus.

5 Undeniable Reasons Your Business Is Ready for a Professional Network

Way to go! Your business has grown at lightning speeds and you’ve been adding new workers and computers along the way. Now that you’re sure everything is on track to succeed, it’s time to level up your network to a robust, scalable setup.

Why? Here are the top 5 reasons to call in the networking professionals today:

Speed: They say time is money, but time spent waiting for a large file to transfer person-to-person or across a bottle-necked system is torture. As a small business this lost time was negligible, but as your business has grown, so has transfer time. While it may only be 5 minutes a day to start, with roughly 260 work days in a year, that 5 minutes a day turns into 21 hours. It all adds up. Unfortunately, the impact of this lost time reaches well beyond the time taken to pass a flash drive around the office or queue up downloads from the internet – it’s a break in workflow and concentration that can almost double the time off-task.

Efficiency: Almost every business requires employees to share digital files. Until now, you may have gotten by with a simple setup and minimal security, but as your workforce has grown, so has your network load. Each computer, storage drive and device adds further burdens onto your network, resulting in a slower transfer, errors, time off task, and even faster hardware failure. A professional network design will give your employees a central file storage location, with the added benefit of auto-saving and backups. No more losing hours of valuable effort or surprise file corruptions, just a scalable, secure server with smooth and efficient transfers.

Collaboration: Employees often need to work together on the same documents. Previously, this required them to take turns, waiting until someone else was finished before the file was available. With a modern network setup, collaboration becomes an organic, profitable way to work. Employees don’t even need to be in the same physical location, opening up opportunities for remote collaboration.

Confidentiality: Every business needs to keep a few secrets. Whether they’re trade secrets or accounting data, you have complete control over who sees what. Your network professional will be able to establish a setup that meets your business’ unique confidentiality needs. Perhaps you’ll have the CEO able to see everything, sales staff can only see sales data, and accounting can only see accounts. Set your access controls based on name, department, role or go further and require passwords for certain folders.

Flexibility: Expand your connection flexibility with wireless networking for employees who are required to roam within the building, Virtual Private Networks (VPNs) for those working at home, or even docking ports for those who switch between locations. A professional network setup will always support the way your business works, both now and as you continue to grow.

Your business’ ability to securely share, store and transfer files will be one of the key contributors to continued growth. The speed, efficiency and flexibility you build into your processes now will save you time, money, and a whole lot of frustration. It’s time to celebrate how far your business has come by looking to the future, with a robust, scalable network that supports your vision.

Give us a call at (416) 645-2469, (905) 667-0441 or email us to discuss your new network.

Internet Lingo 101: Cheat Sheet for Beginners

The Internet is growing and evolving so fast even the dictionary has trouble keeping up. Here are 12 suddenly common terms that are helpful to know.

Browser

A browser is a free piece of software that lets you view web pages, videos and other online content. It’s a core requirement of going online, as it converts the computer languages HTML, Javascript and XML into human-readable form.

The most popular browsers in 2017 are Google Chrome, Safari, Firefox and Microsoft Edge*. (*Internet Explorer has been superseded and is no longer recommended due to security concerns)

Email

Electronic Mail (formerly spelled with a hyphen: ‘e-mail’) is typed messages sent from one person/business to another via the Internet. It’s delivered almost instantly and then waits patiently for the recipient to open and read it.

You’ll need a webmail service (e.g. Gmail) or installed software (e.g. Outlook) to read, write and send, but you can also set your smartphone up for this. Most emails are in the form of letters, newsletters or catalogs, often with a more casual tone. Email can include text, links to the internet and images, but not video/sound.

Encryption

Before important data is sent over the internet, it’s scrambled to turn it into gibberish that means nothing to anybody who might intercept it. Unless there’s been a massive security breach, only the sender and intended recipient will have the decryption key to turn it back into readable data.

You don’t have to encrypt your own data as it happens automatically. Your email provider and important places like banks and online stores have digital security systems that take care of the encryption/decryption for you.

Firewall

A firewall is a security measure designed to act like a door bouncer to your network. When an unauthorized user attempts to gain entry, the firewall blocks their path until it’s checked them out thoroughly. If there’s anything suspicious, the firewall refuses to let them in.

HTTP and HTTPS

These are acronyms for the rules of how data is transmitted to your computer screen. The actual mechanics are incredibly complicated, but the terms have one very important distinction:

HyperText Transfer Protocol (HTTP) means the images, text and links should appear in your browser.

HyperText Transfer Protocol Secured (HTTPS) means the page has an added layer of security to hide your personal information from hackers. Data sent through pages with this prefix is securely encrypted before transmission.

IP Address

Every device that accesses the Internet is assigned a unique IP address to identify itself. It’s used to make sure when you request a page or document, it’s sent to you – and not someone in Alaska. Your IP will look something like ‘202.9.64.55’ and may be referred to as fixed or dynamic.

ISP

Your Internet Service Provider (ISP) is the company that allows you to connect to the Internet. They’ll also offer extra services like email or web hosting. It’s impossible to bypass the ISP level and connect directly to the Internet.

Malware

A broad term to describe viruses and malicious software from hackers. Malware can manipulate you into paying money, take control of your computer, steal your private details or break your computer in some way. Instead of listing each specific threat, you’ll commonly see them lumped together under ‘malware’.

Router

The traffic system for your network, connecting computers and devices within the home and acting as a defensive gateway to the Internet. These hardware devices can be wired or wireless, and allow you to share one Internet connection amongst all the computers/devices in your home.

Social Media

A broad term to describe all the websites and applications that let you share and interact with others online. To fit this umbrella, the site needs to allow user profiles, live updates and the ability to add friends/followers.

The most common social media applications are Facebook and Twitter.

Spam and Filtering

Any unsolicited messages sent over the Internet, usually in bulk, are called spam. Usually, it’s electronic junk mail, but it’s also a technique hackers use to trick people into clicking links to their malware.

Email applications are reasonably good at identifying spam and should shift it automatically to a spam folder before you see it. Occasionally, the filters get it wrong and you may find a relevant email needs to be dragged back to your inbox.

URL

Each website has a unique address on the web known as a URL (Uniform Resource Locator). URLs commonly end in .com but can also end in a country specific extension like .com.au or .fr, or more recently, in new and exciting extensions such as .xyz or .me

Windows Vista End-of-Life: What This Means For You

The countdown is on for Windows Vista users. On 11th April 2017, Microsoft will cease all support and security patching, just like they did with previous Windows versions. Naturally, you’re rather attached to your current operating system and not exactly leaping for joy at this news!

Unfortunately, the longer your computer goes without an upgrade, the higher the chance of a complete system breach. While you’re watching the count-down and thinking about scheduling an upgrade sometime soon, cyber-criminals are making plans of their own. As time progresses, they’ll actively target out-of-date systems and search for vulnerabilities.

Even the most stalwart Vista user must finally upgrade, as continuing to use it will expose your computer to some pretty confronting risks, including:

Security risks: While Microsoft may have patched the gaps exploited during the Vista lifetime, there are many more just waiting to be discovered. It gets worse: your antivirus program is unlikely to intercept these attacks. Hackers are extremely fast to exploit newly-discovered vulnerabilities and without Microsoft working just as fast to close them, the risk increases exponentially every time you turn the computer on.

Compliance risks: For business users, this is a big one. Many businesses are subject to conditions that require them to run an operating system that’s regularly patched. For those working with sensitive, legal or private data, this is even more important. Continuing to use an unsupported OS places not just the system security at risk, but also the entire business.

Software incompatibility: New applications are created exclusively for current operating systems. This means you can’t upgrade past the software you now have, and will soon be phased out of new updates and options across all application types.

No support: Vista mainstream support was stopped back in 2012 but there were always avenues if you were really stuck with something. A quick Google search, an expert on call or even sympathetic support staff at Microsoft helpdesk willing to bend the rules; as of 11 April though, that all stops. The only support available will be outdated pieces you can locate with Google, solutions which may send you in circles with no resolution.

Windows Vista End-of-Life: What This Means For You

The solution is quite simple: upgrade your computers to Windows 10 well before the April 11 deadline.

Windows 10 is the latest release and will give your upgrade investment the most value over time, as well as the best security Windows users have ever seen. Vista will continue to work after April 11, but every day you use it puts your system at increasingly higher levels of risk.
