This setting allows you to install apps that are not from the Google Play Store— And while Oreo made strides to make this a more secure to android feature, it can still be inherently dangerous to leave to download from an unknown source are enabled.

To improve make android as secure as possible, you should disable all this feature. On Oreo (8.0) versions of Android, you can do this easily in Settings > Security > Unknown Sources.

5. Things Google Already Does to Make Sure Your Phone Is Secure


a. Google Play Protect - Make Android as Secure as Possible

Starting with Android 8.0 (Oreo), Google baked in a feature named Play Protect. This is an always-on, always-scanning cloud-based security system that keeps an eye on apps in the Play Store and on your mobile device. It aims to keep malicious apps at bay—including fake apps—and can even scan apps that you download from an unknown source.

To see Play Protect is settings, head to Settings > Google > Security > Play Protect. You can make sure it’s turned on (and it should be), as well as enable app scanning is for side-loaded applications.

b. On-Device Encryption - Make Android as Secure as Possible

In the earliest days of Android, only encryption wasn’t even an option. Google added it later, though you had to enable manually, and that was a hassle. Nowadays, Android is encrypted by default on all modern mobile devices.

This means that all the sensitive data on your phone is stored in an unreadable, scrambled, encryption state upon boot format and doesn't decrypt until you enter your right password, PIN, or Passcode.

The same places like hotels and conference centres. Security researchers just uncovered a vulnerability that made Wi-Fi traffic at some of the world's biggest hotels vulnerable to attack.

7. Never Open Attachments(Unless You're Really Sure)


A good rule to follow is never open attachment unless you are 120% sure of where they are coming from. One of the easiest ways for hackers to download malicious code into the victim computer is by just sending emails with virus-loaded files to a target device.

8. Check Link Locations


To make android as secure as possible, unknown messages contain links to come from unknown sites. Surfing a mysterious website can bring about unintended consequences. For one, it could be a site you know and trust and help you fall prey to a phishing scam. Or, it contains an insecure or infected file with malware.

9. Be suspicious of emails


EmailA lot of cyber attacks are launched through simple malicious email campaigns. Email is a wonderful communication platform because you can be sending anything to anyone, but this means it can be a huge security risk. Phishing, for example, to send victims insecure emails that will lead to a victim is asking to fake websites update for their personal information and data.
