Smartphones

• Internet access is an important feature of smartphones. Generally, you will need to purchase a 3G, 4G, or LTE data plan in addition to normal cell service.

• Smartphones can also connect to Wi-Fi when it is available; this allows you to use the Internet without using up your monthly data allotment.

• Examples of Smartphones: Samsung Galaxy S6, Lenovo A880, LG G4, HTC One (M8), Apple iPhone 6 Plus, Sony Xperia Z2, Nexus 6, Blackberry Passport, Nokia Lumia Icon, Huawei Honor 3X, etc.

Internet Service Provider

• 3G, 4G, and LTE—sometimes called 4G LTE—are different types of networks for cell phones.

• 3G is the slowest of the three networks, but it is also the most widely used.

• 4G has the potential to be much faster than 3G, but most phones are not yet equipped to use it.

• 4G networks are also not available everywhere—you're more likely to be able to use one if you live in a big city.

• As more phones become 4G compatible, the number of people who use 4G and LTE networks will likely grow.

• LTE = Long-Term Evolutionahm80.wordpress.com

9 Common Smartphone Mistakes That Expose Security Risks

password.

- Avoid screen lock patterns which can easily

be hacked.

- Set the phone to lock the screen after one

minute of being idle.

2. Joining Public Wi-Fi Networks

• Hackers can easily steal your information and remotely access your device.

• Otherwise, use your mobile data network.

ahm80.wordpress.com

• Test the functionality.

1. Open Settings on your smartphone.

• Setup your Personal Hotspot

Setting > More..> Tethering and portable hotspot > tick personal hotspot > choose Use WLAN Connection

SSID : ?

Security : ?

Password : ?

- You can make your own security setting and number of user.

3. Not Using An Antivirus & Other Security Software

• Many people don’t realize that a smartphone is actually a computer - malware risks.

• According to the Journal of Information Systems Technology and Planning, over 96% of smartphones do not have pre-installed security software.

• Some good free antivirus software for Android phones include; Bitdefender, AVG and Avast.

• Apple says their iPhones are practically impermeable to malware but only time will tell.

• you also avoid transferring a virus to your computer via USB which is a common problem these days.

ahm80.wordpress.com

Install antitheft software• In addition to that, it is also a good idea to install antitheft

software that prevents access to your phone after it has been stolen. An application such as Prey wipes your data remotely if your phone is stolen.

• To track your phone using GPS, you can also install an app such as Where’s My Droid for Android or Find My iPhone for iPhones.

ahm80.wordpress.com

Practical

• Using Play Store, download application : Prey

• In Device Manager : it’s show you your locaton.

ahm80.wordpress.com

4. Forgetting To Install Those Updates• Smartphone manufacturers and app developers regularly issue

software updates to improve functionality and to patch security gaps.

• In general, you should accept updates to your phone’s operating system as soon as you are notified.

• The same goes with apps running on your phone.

• Make it a habit to regularly update the software running on your smartphone.

ahm80.wordpress.com

5. Not Verifying Your Apps• Few people verify apps before they download and install them.

• By verify, I mean checking to see the developer’s history, prior products, reviews and going online to carry out some basic research before installing an app.

• Many smartphone users download and install apps that come packaged with malware that gives a remote hacker root access.

• The problem is mainly with Android phones due to the relaxed rules required to host an app in the Play Store.

6. Simply Tapping On Links• According to RSA’s cyber security experts, smartphone users

are more susceptible to phishing attacks than desktop users.

• They tend to be less vigilant about security.

• It is harder to spot a fake login page on a smartphone than on a computer.

• Further, shortened URLs make it harder to detect illegitimate addresses.

• The best defense is to avoid clicking on links sent via SMS or instant messaging apps.

• Also, always open email links using your computer.

7. Not Switching Off Bluetooth

• Have you heard of the terms bluejacking, bluebugging or bluesnarfing?

• These all describe a situation where a hacker gains access to your phone using your Bluetooth connection.

• Using this technique, the hacker only needs to be at least 30 feet away from you and you’ll never know what hit you.

• Within seconds, a Bluesnarfer can steal data such as confidential information and even login data to various sites.

• So, unless you are transferring or receiving a file, switch off your Bluetooth connection.

ahm80.wordpress.com

Practical

• Turn On Bluetooth

• Scan for devices

• Paired Bluetooth device

• Send a file / image.

• Turn Off Bluetooth.

8. Forgetting To Log Out

• If you are always logged into Maybank2u, trivago, PayPal, eBay and other sensitive sites where your finances are within easy reach, you might as well leave your credit card /debit card lying on the table at your local eatery.

- Don’t keep your phone permanently logged into such websites.

- Don’t check the box in the app that asks to save your username and

password.

• It is convenient not to have to log into the app every time but it exposes you to considerable financial risk.

• If your phone were to be stolen, a thief would have unrestricted access to your finances and you could end up with a massive bill for things you never bought.

• The same goes for a browser. If you log into sensitive sites, do not give the browser permission to save your username and password.

• Also, make sure you clear your browser history after surfing for sensitive material.

9. Storing Sensitive Data On Your Phone

• I have never quite understood why some people insecurely store credit card PINs, bank online passwords, social security numbers and other such sensitive data on their phones.

• In the event your phone is stolen, it wouldn’t take a genius to figure out that a four digit number stored as a phone contact is a PIN to one of your accounts.

• With a bit more digging, a clever crook can mess up your life.

What are Junk Files?

• Your hard disk is the storage device that holds the entire Windows operating system and all of your important files and data.

• Through normal use of your computer, your hard disk will become cluttered with hundreds or even thousands of Junk Files.

• These junk files are created by Windows and other programs that writes temporary files, during installation and when running, to your hard disk which they need to do in order to work.

• The problem is often that these junk files are not removed from your hard disk, even after they are no longer needed, and waste important disk space for your computer to run optimal.

ahm80.wordpress.com

Please Delete Your Junk Files ……

• A hard drive has a limited amount of space. If you run out of hard drive space, your computer may lockup, crash, or even fail to start-up.

• The more files you have on your hard drive, the more time it can take to access files while using the computer, the more data you have on your hard drive, the performance is much slower.

• Removing the garbage files from your system can regain megabytes or even gigabytes of valuable disk space on your hard drive.

• This will give you more hard drive space for new programs as well as data files like pictures, movies or other important files and helps avoid possible computer issues caused by low disk space.ahm80.wordpress.com

Practical

• Download Clean Master on your Smartphone

- Run Phone Boost

- Delete Junk File

- Run Antivirus

- Clean browser history

- Check CPU temperature
