Free Wi-Fi is available in many locations, from your local café or Starbucks to McDonald’s and many other restaurants. Using these mostly unsecured, public wireless networks puts your information at risk. It is important to employ several safeguards when surfing at a public hotspot. If you are using a cybercafe’s shared computer, we would only use it to view information, not to even get your e-mail. Chance are high that it is compromised.
Many public wireless networks are completely unencrypted so that users can log on to them easily. This opens up a huge security hole as any hacker or sophisticated computer user could easily see all the sensitive data being transmitted. Passwords to online stores or email accounts can be easily captured by increasingly easy to use tools. In this article, we will help you access public wireless networks safely. Settings within your operating system may need to be optimized, additional software installed, and third party services may need to be subscribed to.

Most iPhone users do not think very much about security. The iPhone is part of Apple’s closed ecosystem, helping to prevent viruses and malware from wreaking havoc. As the iPhone has grown in popularity, the smartphone has become more of a target by hackers and criminals. It is important that iPhone users immediately become more vigilant about smartphone security. Our tutorial covers the iPhone through iPhone 7 Plus and iOS through iOS 10.
1. iPhone Software Updates
Apple upgrades the iOS software for the iPhone from time to time. Updates include additional functionality as well as security bug fixes. It is important that users apply updates immediately. Before iOS 5 users needed to connect their iPhones to a computer in order to update the smartphone’s software. Needless to say, this was inconvenient and led to many iPhones with obsolete software.
Always update to the latest iOS software available as soon as possible.
If you Jailbreak your iPhone, you need to be extra careful with regards to security as iOS updates are much more difficult for you. Be careful where you obtain your Jailbroken Apps as malware is much more prevalent.
2. iPhone App Security

The International Travel Security Problem
Many of us travel internationally but few realize how important computer security can be when we visit other countries. People doing business in countries like China and Russia (or any other country for that matter) need to pay strict attention to their technology security protocols to prevent the real and growing threat of high tech espionage. There have been instances of people returning from abroad and having their laptops or smartphones compromised. A mobile device used internationally and later hooked up to the Company’s network provides an excellent infection vector. The folks intent on stealing information could be government or corporate based.

How to Protect Yourself When Traveling
Some people might find the following list a bit paranoid, but you never can be too safe. People that work for major corporations, government, or security firms need maximum protection from attackers. There are tools that can detect the location of a mobile device to within 100 feet and can target phones by the phone number, IMEI (International Mobile Equipment Identity) number and intercept all communications from the mobile device.
- Leave your cell phone and laptop at home
- Buy a phone and SIM card in the other country
- Beware of any SMS message especially if they have links
- Do not bring any sensitive data or passwords
- Use temporary or loaner cell phones and laptops which will be erased when you get home
- Make sure all gadgets are fully up to date and have security software enabled. The best encryption should be utilized
- Never let your electronics out of your site
- If your device gets inspected at the border, it should never be connected to the Company’s network again
- Turn off Bluetooth and Wi-Fi
- Avoid public Wi-Fi altogether
- Do not use a public phone charging cable, it could be capturing video while you charge
- Disable microphones and cameras
- During meetings, turn off your devices and remove their batteries. (Prevents possible recording)
- Use a VPN with heavy encryption to connect to the Internet
- Use Google Voice to create a “throw away” voice accounts
- Do not connect to your Company’s or government’s network while abroad
- Use coded language when discussing sensitive matters
- Cut and paste passwords to prevent keylogging
- Change any and all passwords you used on the trip, immediately
- Enable two factor authentication for services that support this; Facebook, Gmail, eBay, etc.
- Two factor authentication system using SMS text messages is not secure, due to the weak SS7 routing system. We suggest only using two factor when you can use a token or a time based authenticator like Googles.

While SafeGadget has several tutorials geared towards using Wi-Fi securely, we still realize that this is a major problem area. On our recent trip, we encountered insecure Wi-Fi at several airports, hotels, and restaurants. This tutorial is designed to help all users utilize Wi-Fi safely and securely.
Free Wi-Fi is available in many locations, from airports, hotels, local café, Starbucks to McDonald’s and many other restaurants. Using these mostly unsecured, public wireless networks puts your information at risk. It is important to employ several safeguards when surfing at a public hotspot. If you are using a cybercafe’s shared computer, we would only use it to view information, not to even get your e-mail. Chance are high that it is compromised.
Many public wireless networks are completely unencrypted so that users can log on to them easily. Anytime you login to a free Wi-Fi hotspot that does not require a password, assume that a hacker can ease drop and see all information that is being sent and received.
Some Wi-Fi hotspots from vendors like AT&T and Comcast require you to log in with your username and password before you can get access. You need to understand that this is just access restriction and will not create a secure wireless connection.
This opens up a huge security hole as any hacker or sophisticated computer user could easily see all the sensitive data being transmitted. Passwords to online stores or email accounts can be easily captured by increasingly easy to use tools. In this article, we will help you access public wireless networks safely. Settings within your operating system may need to be optimized, additional software installed, and third party services may need to be subscribed to.

Most iPad users do not think very much about security. The iPad is part of Apple’s closed ecosystem, helping to prevent viruses and malware from wreaking havoc. As the iPad has grown in popularity, the tablet has become more of a target by hackers and criminals. It is important that iPad users immediately become more vigilant about tablet security. Our tutorial covers the iPad, and iPad 2.
1. iPad Software Updates
Apple upgrades the iOS software for the iPad from time to time. Updates include additional functionality as well as security bug fixes. It is important that users apply updates immediately. Before iOS 5 users needed to connect their iPads to a computer in order to update the tablet’s software. Needless to say, this was inconvenient and led to many iPads with obsolete software.
iOS 5 allows updates to occur without the iPad being connected to a computer, allowing users to stay current far easier. We recommend all owners of the iPad and the iPad 2, upgrade to iOS 5 immediately. iOS 5 in fact includes many security fixes.
If you Jailbreak your iPad, you need to be extra careful with regards to security as iOS updates are much more difficult for you. Be careful where you obtain your Jailbroken Apps as malware is much more prevalent.
2. iPad App Security
Apple’s App Store reviews all submissions before adding them. All iPad apps must be authenticated and signed which helps to ensure they haven’t been tampered with or altered. This helps prevent malicious apps from infecting the App Store. Apps are prone to security vulnerabilities, that are fixed by updates. Keep apps updated regularly and remove apps that you do not use. Regularly use the App Store app and select Updates. iOS 7 adds the capability to auto update your apps. Be sure to use this function. Apple has the ability to remotely remove malicious apps from your iPad.

- Younger kids may click on links within email, without thinking about the risks
- Not downloading copyrighted material needs to be taught to minors
- Popup warnings from security software are usually ignored
Educating Your Kids
The most important element in creating a safe place for your kids to use the Internet is Education. No piece of software or hardware can replace teaching your kids right from wrong, and candidly discussing all the bad topics that can be found on the Internet.
Some topics parents should cover:
