Secure a mobile device

Cyber attack and viruses are threaten security of our mobile phonep. In addition, threats are always evolving and adjusting based on our habits.
8 mobile security tips to keep your device safe.

1) check Your Phone should beLocked
One potential threat is getting your device is stolen, which could give the thief complete access to your personal information. To prevent this, be sure to have a lock on your screen. Whether this is a passcode, pattern, fingerprint or face recognition is up to you and your phone should be safe

2) Passwords security
Setting strong passwords on your apps will make it harder for a hacker to guess them. It’s also suggested to set a different password for each app. This way if one password is discovered, the hacker won’t have access to all your information.

3) Must update lDevice’s OS Up-To-Date
Mobile phone operating system updates are intended to improve your experience. This could entail anything from performance to security. Although they happen frequently and users tend to click through quickly or ask the device to remind them in the future, it’s important to stay up to date with these. These updates can protect both iOS and Android devices from newly discovered threats. To check if your phone’s OS is up to date, go to “about phone” or “general” and click “system updates” or “software update.”

4) Must Connect to Secure Wifi
The beauty of mobile devices is that we can access the internet anywhere and everywhere we go. One of the first things we do at a restaurant or friend’s house is search for wifi. While free wifi can save us on data, it’s important to be wary of unsecured networks.

To stay safe while using public wifi, be sure to connect to a virtual private network or VPN. Check out Panda VPN for Android, which allows you to enjoy secure Wi-Fi connection even on public networks
5) Beware of Downloads
When you are downloading apps, be sure to download them from the official app stores and check reviews. Cybercriminals create rogue mobile apps that mimic trusted brands in order to obtain users’ confidential information. To avoid this trap, be sure to look at the number of reviews, last update and contact information of the organization.

6) Don’t Jailbreak or Root Your Phone
Jailbreaking or rooting your phone is when you unlock your phone and remove the safeguard the manufacturers have put in place so you can access anything you want. It may be tempting to jailbreak or root your phone to access app stores other than the official ones, but this puts you at high risk. The apps on these illegitimate stores have not been vetted and can easily hack into your phone and steal your information

7) Provide encryption for data
Your smartphone holds a lot of data. If it’s lost or stolen, your emails, contacts, financial information and more can be at risk. To protect your mobile phone data, you can make sure the data in encrypted. Encrypted data is stored in an unreadable form so it can’t be understood.

Most phones have encryption settings you can enable in the security menu. To check if your iOS device is encrypted, go to the settings menu and then click on “Touch ID & Passcode.” It will prompt you to enter your lock screen code. Then scroll to the bottom of the page where it should say “Data Protection is enabled.”

To encrypt an Android, you must first be sure your device is 80% charged, and unroot your phone before continuing. Once these things are done, go to “Security” and choose “Encrypt Phone.” If you don’t charge your device, unroot it or interrupt the encryption process, you may lose all your data. Encryption can take an hour or more.

8) Install Anti-Virus Software
You’ve probably heard of anti-virus programs for laptops or desktop computers, but your handheld computers can benefit from them, too. These programs can protect against viruses and hacking attempts. Some software like Panda’s free antivirus software has VPN features included as an added bonus.

Sync data between mobile and desktop

While phones have become the main computing device for many, most of us still use laptops regularly, too. This means we often need to move files from a PC to an Android phone.

1. Using A USB Cable
The old standard for moving data from your laptop to your phone is via USB. It's still quick and easy, as long as you've got a compatible cable on hand. Unfortunately, the move to USB-C on most modern phones has left a lot of our old cables redundant. They often don't come with the USB-C to USB-A cable you need for most laptops.

But assuming you have got one, then it's simple to do. On Windows or a Chromebook:
Connect your phone.
Tap on the notification Android shows labeled Charging this device via USB.
Under Use USB For, select File Transfer.
That's it. A file transfer window will open on your computer, showing your phone (and SD card if you've got one). Then you can start copying your files across.

The instructions are almost the same on a Mac, but you will need to install the Android File Transfer software first.

This method is good for copying large amounts of data. Try it when you want to transfer some movies or your entire music collection. It makes it easy to move files to your phone's SD card as well.

2. Through Your Cloud Accounts
The Google account you've got set up on your phone gives you access to 15GB of cloud storage space through Google Drive. This gives you a convenient way to move files between your laptop and phone.

You need to install the Google Drive app on your laptop. If you'd rather, you can use Dropbox or Microsoft's OneDrive, as they all work pretty much the same way.

When you set up Google Drive, you need to sign in first. Then select Back up all file types and click ne.

sync google drive folder
This creates a Google Drive folder on your computer. Everything in this folder will sync to and from your Drive account. So to upload files to your phone, just move them into the Drive folder. Open the app on your phone and they'll be there after syncing.

The main caveat to remember here is that the files shown in your Drive app are not stored on your phone. If you try to open one, it needs to download first---and a gigantic file can take a big bite out of your monthly data allowance.

To get around this, you have two options for downloading the files you need to your phone. Select a file, and from the menu choose either:

Make available offline. This downloads the file for you to view offline within Drive. Any changes you make to it will sync next time you go online.
Download. This saves a new copy of the file to your Downloads folder, and you can open it in any compatible app. However, any edits you make won't sync---you need to re-upload the file to your Drive account.

A lack of free space is the main limitation for this solution. You can always set up an extra account though, and it is possible to transfer files from one Google Drive account to another.

3. By Email And Messaging Apps
Emailing files to ourselves is hardly the most efficient way of moving data from a laptop to a phone, but we've all done it at one time or another. It works for quick sharing of files when you can't use any of the other methods.

Portal is convenient because you don't need to install it on your laptop. If you want more features, check out AirDroid, which among other uses lets you send text messages from your PC. There's also Feem, which makes it easy to share files across all different types of devices.

More Ways To Move Your Data
There are more methods to move files between devices. You can use your SD card or a USB flash drive with an On-The-Go cable if your phone supports them. Or for ultra-techie solutions, try using FTP with the Wi-Fi FTP Server app, or even utilizing Network Attached Storage (NAS). With this option, you share a single hard drive with all the devices connected to your network.
