Did you know that power outages are a leading cause of business downtime? According to Inside Energy, power outages are 4X more common today than they were fifteen years ago.

Power outages by the numbers:

  • 80% of outages are caused by the weather
  • 20% of outages are due to human error and equipment failure
  • Outages cost U.S. businesses $150 million per year

Mother nature and human error can cost you thousands unless you have a plan in place to quickly get back to business. Check out this infographic today to learn more about the state of the U.S. power grid and how to ensure your business stays on if the power goes out.

This is our second newsletter highlighting the IoT (Internet of Things), a worldwide network of devices that communicate with one another as they collect, analyze, share and store data collected from sensors. This can be beneficial when used by hospitals to monitor patients, and by governments to monitor traffic, pollution or weather. But the balance tips when the collected data is personal in nature or the receiver of the data has unethical or malicious intent.

There are trust challenges with these devices, which tend to have weak or no authentication but which still connect to protected domains. This allows anyone holding one of these devices to gain privileged access to storage, email and cloud accounts, and other aspects of the "secure" network. Here are 4 recommendations to consider:

Select Network Equipment from Magic Quadrant Leaders

Gartner Group's 2018 report Magic Quadrant for the Wired and Wireless LAN Access Infrastructure lists 3 leaders: Cisco, HP Enterprise, and Extreme Networks. Only these 3 are both visionary with a strong ability to execute. Other providers are visionary, but slow to execute on new ideas, while the rest are followers without much ability to execute.

Cisco Validated Designs (CVDs) provides a design foundation for a broad set of technologies, features, and applications. Every aspect has been thoroughly tested and documented, helping ensure a deployment that's faster, more reliable, cost effective, and predictable. Check out Cisco's Remote and Mobile Assets CVD.

Identify Connected IoT Devices

This can be challenging, as devices may identify themselves with cryptic strings and no manufacturer or product identifiers. Device sniffing tools like Angry IP Scanner will provide snapshots of connected devices, and device-visibility software like ForeScout can provide real-time 100% device identification and control. wikiHow details several ways to Identify Connected Devices.

Segment IoT Networks

Splitting a computer network into VLANs (sub-networks) boosts performance and security, both being important as quantities of IoT devices are predicted to surpass PCs and laptops in 2020. Cisco provides a good video overview of Network Visibility and Segmentation.

Monitor and Manage Network Traffic

There are tools available to monitor and manage network traffic, but most are focused on performance and reliability. Here is a recent diagram of network protocols used by various IoT industries and use models. As you can see, there is complexity at all layers that must be sorted through to gain understanding. Give LeeShanok a call to help with IoT monitoring and management.

Watch for our next IoT newsletter, where we'll focus on IoT in select industries, Industrial and Manufacturing environments being one of the first in our series.

Another ransomware attack has struck - This time the massive attack targeted AriZona Beverages. AriZona Beverages may have been relying on age-old IT systems. In light of this, the news that AriZona Beverages was hit with a ransomware attack last month, and subsequently has spent a fortnight rebuilding its network, might not come as a massive shock to some.

What You Can Do

This is one of the trickiest cyber threats out there because just relying on routine backups may be enough to not protect your business. Backups need to be clean and have been done prior to infection. Discuss your backup architecture with a professional to be sure you are truly creating a clean version of your data each time it is stored in backup. A managed plan can do this for you regularly.

LeeShanok IT News: End-of-Support / End-of-Life

2019 is an important year in that some of the most popular operating system and productivity software revisions will reach End of Support in 2019 or 2020, after which security and reliability patches will no longer be released by the manufacturer. With perpetual licensing, your software will continue to run after the EOS date, but it will become increasingly vulnerable to malicious attacks and instability resulting in freezes or crashes. This progression is particularly risky with server and gateway class devices, which can impact an entire organization and take time to correct.

Many of these upgrades require project planning, financial outlay and resource downtime, so it's a good idea to begin planning up to a year in advance. If you are unsure of your situation, our team is available to help you evaluate and plan.

Red - Past End-of-Support, needs replacement ASAP.

IT News - Chrome Vulnerability

When you prepare to leave work, do you shut down or restart your computer?

If not, it's unlikely you restart it when you arrive at work either, meaning Windows and your web browsers continue running un-patched and un-protected. This is a problem with the newest zero-day vulnerability in Google's Chrome web browser, and Malwarebytes warns ... "Considering how many users keep Chrome and all their tabs opened for days or even weeks without ever restarting the browser, the security impact is real." 0 PC Magazine echos the caution: "If you don't close Chrome, updates will not be applied." 1

To complete installation of many Windows patches, you must restart your computer. Updates to Chrome usually remind the user to restart the app, but more significant Chrome patches also require restarting your computer.

You ask "What about my tabs, I use the same tabs every day?" Chrome saves open tabs when you restart the app with the "chrome://restart" command, or restart your computer while Chrome is still running. Still not convinced? Start Chrome, open several tabs, then in the address field, type "chrome://restart" and watch the magic. Chrome will shutdown and restart, restoring all previously opened tabs.

Now let's update Chrome.

Update Chrome on Windows PC or Apple Mac

If Chrome has an available update, it will begin applying it immediately.

After updating, always restart Chrome. Better yet, restart your computer by typing in Chrome's address field type "chrome://restart" which will save and recreate your open tabs. When Chrome restarts, in the address field type "chrome://help".

Update Chrome on iPhone, iPad

You may have your apps set to update automatically, but it's wise to verify this patch. Settings > iTunes & App Store > Updates. Make sure it's green and enabled as shown.

Then open App Store and apply update to Chrome if available.

Update Chrome on Android

Settings > Google Play Store > My Apps & Games

If the button is labelled [OPEN], your Chrome already has the latest update. But if you see [UPDATE], click it to update Chrome.

IT News - Social Network Security

Threats to your social network aren't new, but the frequency and cleverness of attacks and the cost of repairs make it vital to keep your awareness fresh and defenses strong. Reacting to a breach can require far more time, effort and cost than preventing one.

Attacks come from:

  • Viruses & Malware - Relies on users to share malicious links with their contacts, then replicates itself to other devices
  • Ransomware - Encrypts user data demanding payment to unlock it
  • Phishing - Impersonates social contacts to encourage execution of malicious code
  • Spamming - Sends out numerous emails resulting in blacklisting
  • Identity Theft - Gathering personal information from social networks, attackers assume your identity or the identity of your contacts
  • Apps - Games, puzzles and quizzes can be given access to your profile and contacts and subsystems of your device (e.g. location, camera, microphone) without your knowledge
  • CEO Fraud - Impersonates company executives and key employees so that lower level employees open emails, links and attachments

Visualize social network security like layers of an onion. Your network firewall is your first line of defense, scanning inbound and outbound internet traffic, filtering content and detecting intruders. An email spam filter scans and quarantines suspect inbound and outbound messages. Endpoint protection keeps malicious code from entering and running on devices we use, which includes computers, tablets and smart phones.

Inspect the privacy and security settings on your devices and in your email and social accounts, and use strong settings when available. Avoid installing new third-party applications from unknown vendors, and limit their access with your privacy and security settings. Limit the amount of personal information you post to sites, remembering that your posts will last a long time. And share with friends, but limit automatic sharing with "friends of friends". For those being especially targeted, most email providers offer Advanced Threat Protection for a few dollars per month per user.

The most effective protection is you, a vital link in the "human firewall". Look before you click, think before you open, verify before you trust. In your email client windows, look over the sender's email address and subject, and preview the message before opening it or picking any links or attachments. If something feels amiss, it probably is. Right click on the message and move it to "Junk" (spam) folder.

Contact us to schedule a free phishing security test of your employees, followed by our IT Security for the Common Worker lunch-n-learn workshop. There is no cost for either, other than several hours of labor to deliver these services.
