Is it safe to install iOS 11 and if I do, can I uninstall it if I don't like it?

Wed, 8 Nov 2017 00:00:00 +0700

(image) Apple routinely releases a new version of its operating system, better known as iOS, whenever it introduces new phones.

iOS 11, which is the most recent major update, was released on September 19th followed by a minor updates on September 26th (11.0.1), October 3rd (11.0.2), October 11th (11.0.3) and October 31st (11.1).

As of this writing, 11.2 is in beta testing and should be released in the near future as the common complaint of reduced battery performance seems to have cropped up as it has with many past versions.

Understanding Build Numbers

This version numbering sequence (build number) is a general way to denote improvements over previous versions.


With this being the 11th major version of iOS, we have seen a pattern with every new release that is helpful to understand.

When you see the first number change, say from 10 to 11, you’ll know that it’s major update with a lot of new features.  With major updates come lots of undiscovered bugs and security issues which quickly become exposed as millions of eager users install and use the update.

When you see a version change from X.0 to X.0.1, this usually indicates a very minor update usually focused on bug and/or security fixes.  When you see a change from X.0 to X.1, this usually indicated a relatively minor update often accompanied by a feature update or two along with the bug/security fixes.

If you look at the update history of all 11 versions of iOS, you’ll see that it’s not uncommon for the version to go through a large number of updates until the final version is released.

iOS 10, for instance, had eleven different updated before it settled on 10.3.3 as the finalized version.

Minimizing Issues

For the most part, if you look back at the historical update patterns, waiting until you see version 11.2 or 11.3 would greatly reduce your chances of being part of the ‘guinea pig’ pool that helps Apple identify issues and bugs.

No Going Back

In the first couple of weeks of the iOS 11 release, there were ways to revert back to iOS 10.3.3 if things were not going well, but they were pretty involved and required you to have a proper backup before upgrading.

As of October 3rd, Apple made a change to how it addresses reverting which made it impossible to go back to iOS 10 once you’ve gone to iOS 11, so there is no going back.

General Rule of Thumb

As with any update, not everyone is going to experience issues because we’re all essentially running a unique combination of hardware and apps.

Before you install any iOS update, you can always click on the link in the description to see what new features are being added and what bugs or security issues are being addressed.  If the new features aren’t that compelling (like new emoji) or you’re not experiencing any issues listed, holding off on the update makes sense unless Apple expressly denotes that it’s a serious security patch.




What exactly is the 'deep web' and how to you get to it?

Wed, 1 Nov 2017 00:00:00 +0700

(image) Despite many representations of a nefarious underground operating out of sight, the deep web is actually mostly benign private databases and web resources not meant to be accessed by the general public.

The ‘surface web’ is essentially what can be indexed by search engines like Google or Bing, while the ‘deep web’ consists of items that can’t be accessed using a search engine through a standard web browser.

Protected Internet databases like those for banks, anything past a log in screen, like your private files stored in the cloud and data stored by private companies aren’t indexed by search engines. Websites can also specifically tell the search engines that they don’t want to be indexed making them relatively ‘invisible’ to the average user.

Most estimates put the deep web in the 90% range of the entire Internet because so much of what is stored online is protected information that requires some form of authentication or knowledge of a hidden web address.

The Dark Web

There is a very small percentage of the deep web where secret and sometimes nefarious activity is taking place, often referred to as the ‘dark web’ or the ‘darknet’. The tools used to access the dark web focus on anonymity by incorporating encryption and specialized privacy browsers like Tor.

Tor, also known as ‘The Onion Router’, uses a large network of relays to bounce Internet traffic through; it’s much like the layers of an onion, to make it much more difficult for anyone conducting any type of surveillance to see who is doing what.

The core technology used in Tor was actually developed by the US Naval Research Lab in the mid 90’s for use by the intelligence community for protecting online communications. To this day, Tor and other similar tools are used by governments, activists and whistleblowers to communicate anonymously.

The Tor Project states: “Tor users include ‘normal people’ who wish to keep their Internet activities private from websites and advertisers, people concerned about cyber-spying, users who are evading censorship such as activists, journalists, and military professionals.”

Using Tor alone doesn’t mean you’re completely anonymous and for most users, the trade off in slow performance isn’t worth the increase in privacy for daily surfing.

Tor’s Dark Side

Tor and other similar tools are also being used for illicit activities such as buying and selling drugs, stolen credit card numbers, stolen IDs, money laundering and more via black markets only accessible on the dark web.

One of the most famous dark web marketplaces was called Silk Road, which was shut down by the FBI in 2013. The site’s founder, Ross Ulbricht, was sentenced to life in prison without possibility of parole.

Despite law enforcements attempts to control illegal underground marketplaces, when one is shut down, two more seem to pop up.

To be fair, not all dark web resources operate in an illegal manner and much of the activity taking place is vital to our law enforcement and intelligence community’s efforts.  As with any technology, it’s impossible to control its uses for only legal purposes, so as always, it’s the good with the bad.




What's your opinion of the various smart firewalls?

Thu, 26 Oct 2017 00:00:00 +0700

(image) With the growing popularity of Internet connected devices in the home, like web cameras, thermostats, doorbells and lighting systems – often referred to as the ‘Internet of Things’ – securing those devices is a critical step in keeping them safe.

‘Smart firewalls’ are an emerging category of security products designed to help users protect all their connected devices.

The Latest Attack Vector

IoT devices are becoming a more popular attack vector for the underworld because of their sheer numbers. Current projections expect the number of IoT devices to exceed the number of mobile phones in 2018 with an estimated 18 billion IoT devices in use by 2022.

Hackers go for easy targets and with the relative lack of focus on security by both manufacturers and consumers, IoT devices are in their crosshairs.

Easy to compromise devices are being ‘recruited’ to become a part of an army of devices known as a ‘botnet’ that can wreak havoc in a number of ways. Botnets allow the controller to direct thousands of devices to attack a specific website, essentially making it inaccessible to real users (aka Denial of Service attacks).

Users of compromised computers and IoT devices rarely have any idea that their devices are being used for malicious purposes, which is where smart firewalls can help.

The recent discovery of the KRACK Wi-Fi security hole (https://goo.gl/4qv4ur) is just another reason to take security seriously, especially since some IoT devices can’t be updated to fix newly discovered security holes.

How They Work

Smart Firewalls are hardware based devices that can do a better job of managing lots of devices versus a typical software firewall. The ‘smart’ portion of the device analyses your network traffic in real time to identify threats or suspicious activity, block them and notify you of the activity.

This approach to network security is common in sophisticated business networks with tech savvy administrators that know how to configure powerful routers.

Smart Firewalls takes the need for tech skills out of the equation, because they’re generally pre-configured to start protecting your entire network as soon as you plug them in.

Early Stage Development

The first devices in this category started appearing in just the past couple of years, so we’re in the early stages of development.

Some of the early entrants like the Bitdefender Box (https://goo.gl/Rg1Yx8) are in the process of releasing their second generation products while the Cujo (https://goo.gl/AsbuhE) has received lots of praise for its ease of setup and use.

Another newcomer is the Norton Core (https://goo.gl/ueewTA), which is one of the more expensive solutions that’s so new that there not much of a track record for it.

Virtually every option available requires either a monthly or yearly subscription to provide their cloud based threat analysis, so make sure you include this ongoing cost in your comparisons.

There are devices that don’t require a subscription, such as the RATtrap (https://goo.gl/ztL6sT), but some users have complained about slower Internet speeds and it won’t work with modem/router combo devices.

This category of devices is so new, I’m personally going to wait a little while to see how things shake out before committing to any of the platforms.




Apple released the iPhone 8. What's new, what's improved and is it worth the upgrade?

Tue, 17 Oct 2017 00:00:00 +0700

(image) Apple officially started selling the iPhone 8 (and 8 plus) on September 22, 2017 and we've had our hands on one for a couple of weeks now. At first appearance it looks and feel like previous designs (iPhone 6, 6s and 7) but it's what's inside that really counts! The exterior has the same physical dimensions, so existing users cases/accessories will fit and work as before (no need to upgrade those too)! The back of the iPhone 8 is glass now, but Apple insists that it is as tough as the aluminum backed phones of previous generations. Time will tell. The headphone jack is still missing (removed with the iPhone 7 gen) and the "home" button still isn't a "real" button (like the previous phone gen too) - so again, there's not a real "wow" factor to the the visible physical device. Under the hood, there have been LOTS of changes.

First, wireless charging has finally come to iPhone. It's been on rival phones for years now, so it's about time! True Tone tech adapts white balance to wherever you are at to keep colors "accurate" while viewing. Upgraded Bluetooth and cellular radios provide for more reliable connections. The cameras have been updated and feature a 12-mega-pix back cam and 7 mega-pix front facing camera. HDR mode is on by default now, resulting in better images. The iPhone8 seems to be edged out in low light shooing by the Samsung 8/8+, but only slightly. Slow-mo video in 1080p is awesome along with 4K video at 60fps looking so good, video almost looks not real! Finally, better speakers make for an improved audio experience.

While the iPhone 8 may not be obviously different from the outside, it seems to magically "just work" better. It's faster, smoother and more efficient thanks to the internals being completely reworked. While it's definitely the "Best iPhone yet", we can't help but look forward to the iPhone X set to release in early November 2017 - the device that's changing the rules when it comes to mobile phones. If you don't want to wait or want to avoid the $1000 plus price tag, the iPhone 8 may be just the phone for you!




What suggestions do you have for managing the mobile devices in our business?

Thu, 12 Oct 2017 00:00:00 +0700

(image) It’s no secret that more business is being done on mobile devices then ever before, as mobile Internet access surpassed desktop usage for the first time back in November of 2016.

Since these devices have become so invaluable for conducting business, every business should be thinking about how to manage them.

Single Biggest Risk

The likelihood of a mobile device being lost or stolen is exponentially higher than a desktop computer, so planning for this eventuality is critical.

Since passwords and access codes are commonly stored in browsers and apps, anyone that gets their hands on an unprotected mobile device can instantly assume the identity of the victim and wreak major havoc.

Computers, tablets and smartphones that don’t require a password or passcode in order to use them should be strictly prohibited in any business.

Basic Protection Layers

Even with an access password enabled, a motivated thief can make their way to your sensitive data, so using some form of encryption and installing a remote tracking program provides additional layers of protection.

Apple devices running iOS 8 or higher are encrypted by default and Android users can search for ‘encryption’ in their Settings menu to activate it.

While both Apple and Google offer free tools that will allow you to track, lock down and remotely erase lost devices, they lack some of the more useful features available in third-party options.

Pictures Can Help Recovery

One of my long-standing favorites is Prey from https://PreyProject.com because it adds the ability to take screen shots on laptops as well as take pictures of the user from the camera(s) on any of your mobile devices.

This can become critical, because simply determining the general location of a device isn’t much help if it’s a huge apartment complex or a 20 story commercial building.  Your chances of getting any type of help from law enforcement goes up if you can provide more than just location information.

The free version of Prey covers up to 3 devices, but no longer includes the ability to remotely erase your data. You can either opt for their $5 a month package for that feature or use Prey along with the free tools offered by Apple or Google.

Large Scale Systems

If you have a large number of devices to manage, you’ll want a more sophisticated platform.  Prey offers customized business packages, but for a much more comprehensive set of tools, look to solutions such as AirWatch from VMware (https://goo.gl/4Fw6gM), Meraki from Cisco (https://goo.gl/V1g2Tw) or Intune from Microsoft (https://goo.gl/8gXQqt).

These tools dramatically expand your management capabilities to include limiting the mobile devices that can connect to your network, controlling what data those devices have access to and various tools that makes deploying and managing a large number of devices much more efficient.

These more sophisticated tools allow IT managers to better control what can be done when an employee is using their personal device for business without restricting their personal needs.

The cost of these more sophisticated tools can range from a per device charge (starting @$2.50 a month for AirWatch Express https://goo.gl/RUxP35) to a per user charge used by Microsoft.




How hard is it to convert from an Android smartphone to an iPhone?

Thu, 28 Sep 2017 00:00:00 +0700

(image) In the world of smartphones, the Android vs iPhone battle is similar to Ford vs Chevy with passionately avid fans on both sides.

However, converting from a Ford to a Chevy is a lot less involved then going from an Android to an iPhone.

The good news is that it’s a lot easier than it used to be, but you do need to do a little homework before you attempt the conversion.

Will It Fit?

Your first step is to determine what on your Android handset needs to be transferred to your new iPhone.  Unlike the iPhone, many Android phones have the ability to expand the base memory, so if you have a micro SD expansion card loaded with music and pictures, everything may not fit on a base model iPhone.

Apple charges $100 to $150 as a premium to go from its base model to the expanded memory options depending upon the model you’re buying.

Base models either come with 32Gbs or 64Gbs, so make sure you’ve done the math to figure out what will make it over.

Deleting the items on your Android phone that don’t need to transfer before you get started will make the transfer process less complicated, especially if you’re dealing with too much content to transfer.

Also, be sure you have the latest version of iTunes on your computer as well, as this will be your main management console for the iPhone once you’re done with the transfer.

Move to iOS App

Several years ago with the launch of the iPhone 6, Apple released an Android app called ‘Move to iOS’ (https://goo.gl/1hsNYy) to help switchers with the process.

It’s far from perfect, but it does take a lot of what used to be a manual process out of the equation (instructions: https://goo.gl/8uEZou).

The app only works if you’re transferring to an iPhone that has yet to be setup, so if you’ve already started using yours, you’ll either need to reset it (which wipes everything off) or move everything over manually: https://goo.gl/JJHukR

There are many limitations to what it can transfer over as well as the lack of converting various media files, so if things like auto-conversion of your music and videos, attachments in text messages, call logs, ringtones and other random files are important to you, it may be worth buying a program called AnyTrans (https://goo.gl/s4g7Hz).

AnyTrans, which uses your computer with both phones plugged in to get the job done, also lets you avoid having to reset your iPhone if you’ve already started using it.

Managing Your Expectations

Despite all of the advancements made in transfer options, you’re still likely to run into issues or glitches, so be prepared for a period of adjustments.

Also, keep in mind that all the apps available for the Android aren’t necessarily available for the iPhone and purchased apps often have to be repurchased from Apple.

If you use a lot of Google’s services, simply adding the iOS app for each and signing into your account should make everything ‘automagically’ appear on your new iPhone.




Is there a voice recognition system that can replace typing that actually works well?

Thu, 21 Sep 2017 00:00:00 +0700

(image) As much as technology has advanced since Bell Labs developed the ‘Audrey’ in the 1950’s, which could only recognize digits spoken by a single user, we’re still far from what you’ve seen in science fiction movies.

Commands vs Dictation

Voice command platforms like many automated phone systems use are reasonably effective because they severely limit the number of verbal commands you can use.

Natural speech recognition is what most people want and that’s a challenge that has yet to be met in a way for it to be widely adopted.

We’re surrounded by options that offer some form of voice command/recognition from Apple, Google and Amazon, but they are far from perfect, as we all well know.

Accurate dictation has been the challenge that many very sophisticated companies, including IBM, have been trying to solve for over 60 years.

To put the problem into perspective, a system with a 90% accuracy means that every 10th word is wrong. 95% accuracy gives us a 1 in 20 ratio and even at 98%, we’re still looking at roughly 1 in 50 words being incorrect.

With an average paragraph in the 100 – 150 word range, you can start to see how the time we may save in generating the text can get eaten up in editing what was captured.

Throw in that our voices change when we’re sick, various accents, the speed in which we speak and a host of other variables and you start to understand how much more sophisticated of a processor the human brain is.

The Context Problem

Another huge challenge is context, both in command and dictation technology.  Google recently started to bridge the context gap with their latest Google Assistant technology that allows you to have more of a conversation.

For example, you can ask ‘Do I need an umbrella today?’ and after it responds, you can follow up with ‘what about tomorrow?’.

Another advance in context is being made possible by what many consider the ‘creepy’ factor of today’s technology.  Since our smartphones can remember virtually everything we’ve done in the past, consider our current location or what we’ve been searching for online or in a mapping program, they can use this additional info to help better understand your verbal commands.

Tips for Being Successful

If dictation is your key need, the company that’s been at it the longest, as far as a consumer product goes, is Dragon NaturallySpeaking (http://dragon.com).

As good as the program is, expecting to install the software and have it magically become your new way of ‘typing’ will guarantee failure.  You are essentially going to be learning a new language in a sense.

If you aren’t willing to take the necessary time to train yourself to learn how to speak to your computer, you shouldn’t bother spending the money.

You’ll also need to make sure that you have the proper hardware to be successful, such as enough processing power, RAM and a good microphone, so be sure to review the system requirements before taking the plunge.




I'm ready to upgrade my iPhone, but I can't decide which way to go. Any tips?

Thu, 14 Sep 2017 00:00:00 +0700

(image) There has never been a better time to be in the market for an iPhone as the current selection includes 8 different models - the entry level iPhone SE, 6s, 6s Plus, 7, 7 Plus, 8, 8 Plus and their top line X - that range in price from $349 - $1149.

Start with Screen Size

If you haven’t already done so, make sure you hold each of the phones in your hand and slide it into your pocket or pocketbook to determine the best fit from a form factor standpoint.


Budget minded consumers that don’t care about larger screens, can opt for the 4” SE - the size of the original - for the new reduced pricing of $349 - $449 depending upon your storage needs (32GB – 128Gb).

If you want a slightly larger screen (4.7”), then your choices are between the iPhone 6s, 7 and 8.

If you want a phone with the largest screen size, then your choices are between the 6s Plus, 7 Plus, 8 Plus and X.

Cameras

iPhones have long been heralded for their camera technology, and unless you’re really into photography or super hi-res video, every model has a 12MP camera that can shoot 4K video at 30 frames per second (fps).


If you’re a big selfie or Facetime fan, you’ll want to stick to the iPhone 6 or better as the front facing camera on the SE isn’t great.

Water and Dust Ratings

If you spend a lot of time outdoors, especially near water and you want something that can take a bit more abuse, you’ll want to go for an iPhone 7 or higher as they all have superior water and dust resistance ratings.

Despite the ratings for having your phone in 1 to 1.5 meters of water for up to 30 minutes, you really shouldn’t plan on swimming with them.  Exposing your expensive phone to salt and chlorine water isn’t something I’d recommend without something like a LifeProof case (http://lifeproof.com).

Newest Features

If things like wireless charging, fast-charging, 60 fps 4K Video and the most powerful processors available are important to you, then you’ll probably be able to justify buying the iPhone 8, 8 Plus or X.

Apple’s comparison site is an easy way to compare up to 3 different models at a time to help you weed through the specs: https://goo.gl/JeJJ7V.

Purchasing Options

There are a plethora of options for buying new, used or refurbished iPhones, starting with Apple itself.

Apple offers an annual iPhone Upgrade Program, which is best for those that have to have the latest model every year: https://goo.gl/vknWpT, look into their trade-in program for your older iPhones: https://goo.gl/W2nEQ3 or shop for deals in Apple’s refurbished inventory: https://goo.gl/M1CSFg.

If your current phone is tied to a specific cellular provider, check to see what their current promotions are based on your eligibility.

If you don’t mind a used iPhone, besides your cellular provider, there are a number of reputable resources that I’ve used to pay cash for a used phone including Glyde (https://glyde.com), Swappa (https://swappa.com) and Gazelle (https://gazelle.com).




Is it true that if I enroll in the free Equifax protection program that I can't be part of a class action lawsuit?

Fri, 8 Sep 2017 00:00:00 +0700

(image) In what may be one of the most damaging data breaches to date, Equifax - one of the big three credit bureaus, announced that 143 million US based consumers may be affected by a data breach that occurred between May and July of this year.

What makes this breach so damaging is that the most sensitive personal information including Social Security numbers, birth dates and home addresses was part of the breach.

Equifax TrustID Premier Enrollment

In an effort to provide some level of protection to impacted consumers, Equifax has launched a special website (https://equifaxsecurity2017.com) to explain what has happened and to offer their ID theft and credit monitoring service for free to anyone that wants it.

Many have pointed out the irony of going to the very organization that couldn’t keep its data secure to protect you from further damage.

These types of ‘free’ services typically only last for a year, which doesn’t really do you any good in the long run since you can’t change your social security number very easily.

The ‘Terms of Use’ for TrustID Premier has a pretty common arbitration clause that includes:… A WAIVER OF THE ABILITY TO BRING OR PARTICIPATE IN A CLASS ACTION, CLASS ARBITRATION, OR OTHER REPRESENTATIVE ACTION.  (You can read the entire statement at https://goo.gl/1ZtvgD.)

UPDATE: Equifax has updated their FAQ on this question with the following: The arbitration clause and class action wavier included in the TrustedID Premier Terms of Use applies to the free credit file monitoring and identity theft protection products, and not the cybersecurity incident.

Enrollment for the free one year subsciption ends on November 21, 2017

‘Pretexting’ Concerns

One of the most disconcerting aspects of this breach is that the sensitive information that was stolen is extremely useful for a form of ‘pretexting’ that could have nothing to do with your credit file.

Pretexting refers to the act of pretending to be someone in order to gain access to private or sensitive information.

In this case, your information could allow a perpetrator to pretend that they are you to convince your bank, utility, cellular provider even the IRS to change something like an email address or physical address because the typical information required to prove your identity is in the hands of the bad guys.

Tax Filing Concerns

Another big area of concern will be for the tax-filing season next year. The filing fraudulent tax returns has become a billion dollar problem and this breach just made it easy for this problem to grow.

Make a note in your calendar to file your tax return as quickly as you can next year to avoid the mess that’s created if a fraudulent return is filed before you file your real tax return.

Children’s Credit Files

ID thieves covet the Social Security number of children because it’s a lot less likely that anyone is monitoring the credit of a young child.  Whatever you decide to use to monitor your own credit files, don’t forget your children as well.

Credit Freeze

One of the best ways to lock down your credit file is to put a freeze on it with all 3 credit bureaus: https://goo.gl/kfKWw2




Where do I turn off the constant location tracking in my smartphone?

Thu, 31 Aug 2017 00:00:00 +0700

(image) Our smartphones have become a virtual human ‘electronic tag’ that instead of being installed under our skin, is in our pockets and purses.

Precise locations, dates, times, durations and what we did before and after opening an app or website are just the beginning of what’s being tracked.

The very design of the device allows this to happen whether we want it to happen or not.  Your cellular provider, for example, always knows where you’re at on their network, because your phone is checking for the strongest cell tower roughly every 7 seconds.

Turning off all of the location tracking systems on your smartphone would essentially render it useless, but you can somewhat control what gets shared or stored.

Personalized Services

Both Google and Apple will espouse their ability to provide their users with ‘personalized services’ by allowing your smartphone to constantly track your location.

For example, it can detect that it’s the time of day you usually leave for work and automatically estimated your commute time and best route based on the current traffic conditions.

Apple’s frequent location data is only stored on the iPhone, while Google stores your location history both on your Android handset and in your Google account.

For the most part, someone would either have to gain access to your smartphone or your Google account to see your detailed location history.

Keeping Location Data in Perspective

Frankly, if someone does gain access to your smartphone or Google account, your location history should be the least of your worries.  Your email account and its contents are far more valuable to a cyber-criminal than your location data.

If your concern is that your spouse will be able to see your every move, then that’s a completely different situation that may be dictated by your relationship.

Whatever your reasons are for not wanting your location data tracked and stored, it’s pretty easy to turn it off.

iPhone Frequent Locations Setting

Most iPhone users are likely familiar with the ‘Location Services’ options in the Settings menu (Settings/Privacy/Location Services) that allows you to individually control which apps have access to Location Services.

If you scroll down to the bottom of the listing of your apps, you should see an option for ‘System Services’. Tap it and look at the bottom of the next screen of options to tap on ‘Frequent Locations’.

You should now see a toggle to turn on or off ‘Frequent Locations’ and the current ‘History’ that’s stored on your phone with an option to Clear History if want to wipe the data.

Google Location History Setting

Android users will need to adjust setting in two different areas: on your smartphone and in your Google account.

Android devices have slightly different Settings menus depending upon your device, so look for (or search for) ‘Google Location History’, which is usually under a Privacy or Location submenu.

When you toggle the switch to off, it simply stops storing your locations but does not delete your history.

For complete instructions to manage or delete your Location History, go here: https://goo.gl/gKuAs3.
