People get offended if you say anything about their phones but are very insensitive towards their smartphone security.
We’ll discuss the addiction to mobile phones in some other post. Today’s topic is not about the addiction of mobiles.
You need it every time. It is your best friend, teacher, guide, all in one. You check emails, take selfies then upload to social media, make transactions, make voice & video calls, play games, and much more.
It is just very very useful but you’re very much exposed to the Internet with it. There are thousands of viruses and other malware that are ready to spoil your peaceful life.
Earlier Android updates were not so secured but the Latest updates like Oreo, Pie, etc are secure enough. Read About the sweet journey of Android.
You can improve smartphone security without antivirus. And Today I am going to tell 13 simple ways to improve smartphone security without antivirus. Let’s start.
Tips to improve smartphone security
#1. Avoid installing apps from a third-party source.
This is the key to improve smartphone security. Third-party websites look fancy, offer many things to attract especially paid apps for free. It is the most common reason for using a third-party source. It looks great that a particular site is availing of the paid apps for free.
But, this can be a dangerous threat to smartphone security and it becomes more dangerous if you use it for payments. Those apps may have any type of malware attached to it.
And so, I strongly recommend you to install apps only from the store because Google and Apple regularly check all apps. If they found anything suspicious then they immediately remove the app from the store.
#2. Be careful while granting permissions to apps
You have installed the app from a trusted store, even then you should be careful while giving permissions. We have seen many apps asking for completely irrelevant permissions. For example, a flashlight app was asking for permission to access calls, contacts, and camera.
Now, just think what’s the need for calls to turn on the flashlights?
It has nothing to do with any feature of the app. It is called data mining. The store algorithms only scan for malware attachments but do not focus on these things.
And so, you will have to be careful if you want to be protected. Keep permission monitor on so that the system can notify you when an app running in the background uses any resource.
Any sensitive granted permission to a malicious application can ruin all your smartphone security measures.
#3. Turn Off “Install Unknown apps”
Sometimes when you visit malicious websites through which malware gets installed on your device without your knowledge. This can cause problems for your device security.
Another thing lets suppose someone with intentions gets your mobile phone and (s)he has a malicious application like spyware. then (s)he can easily spy on you.
But if you keep “Install unknown apps” off and have set a lock to your settings then the risk of installing malicious scripts would decrease. And your loving mobile phone will be secured.
#4. Use a strong password and lock.
Well, it is not rocket science. Even children of today know that the importance of locks and passwords improves smartphone security. But let me make you understand it more.
Suppose you have installed a third-party app lock or antivirus. Now if I want to bypass your security system then I would simply uninstall the app and do whatever I want.
Ok, now you are smart and set the uninstall protection on for that particular app. But you haven’t locked the settings. Now, again I can uninstall the app by making some permission changes in settings.
So, Use security features wisely. And Use strong, unguessable passwords if you want to be secure.
#5. Avoid visiting malicious websites.
Are you addicted to adult sites? If yes, then this is for you. Adult sites are one of the main sources of malware. When you visit an adult site. you start getting a bunch of pop-ups asking to download something or install browser extensions.
These types of sites are only dependent on traffic and ads. And so, they want as many clicks as possible from you in order to maximize their traffic and ad revenue.
Small websites have very few economic incentives to keep their existence. And so, they just use whatever software plugins are available to maximize traffic and user clicks.
Hackers will then exploit these weak plugins to infect the ads or popups, which in turn infects you, the end-user.
And by visiting these websites without having knowledge about it means that you are compromising your smartphone security by yourself.
#6. Encrypt your SD card
So, you have done all these things that I mentioned above. But, you have a Micro SD card inside your Mobile phone. Then Anybody can take out that card steals your information and more dangerously can put some malicious files.
When you click on that file and your phone will be infected.
To avoid this, the very simple method is to encrypt that SD card, so that nobody can write anything to that card.
#7. Never Click on unknown and suspicious email links.
This is very common, Anybody having some knowledge about cybercrime knows that these links can be extremely dangerous. Spammy malicious emails are the major threat to smartphone security or any type of digital device security
When you click on these links, some malicious scripts start executing in the background without your knowledge. For example, Ransomware malware comes with email. When a victim clicks, it starts running in the background and encrypts the whole computer.
Sometimes, these emails also contain phishing pages links like Social media, banks. People see attractive deals and just enter all the credentials without thinking once.
#8. Avoid non-HTTPS sites.
Well, Non-HTTPS sites may not directly harm your device but these sites have unencrypted connections and hence, it becomes very easy for an attacker to manipulate the connection according to him.
An attacker may manipulate the connection and redirects the page to a malicious page that can harm your device in the same way as I mentioned above.
As I mentioned, Non-HTTPS sites have an unencrypted connection and hence these sites are a soft target for attackers. Because Whatever you enter on a non-https site is sent to the server in plain text.
#9. Do not use a public network for transactions or download.
In most of the cases, public networks have weak and insecure connections. And whatever you surf using that network has to pass through those connections.
Now, suppose your home wifi has a wide range that your neighbor is also in the range of your home network. But, your neighbor won’t be able to what you are browsing on the Internet. Because you have an encrypted connection between your device and your router.
But, In the case of Public Network, the connection is unencrypted and insecure because you just connected without entering a passphrase. Now, anybody with tools like Firesheep and Wireshark can see what unencrypted web pages you’re visiting.
To avoid this you can use a VPN that I’m going to explain in the next point.
#10. Use VPN To Ensure your Smartphone security
Virtual Private Networks (VPNs) can be extremely helpful if you use public networks to access your social media accounts as well as making transactions.
It makes a private tunnel to access any website. It’s like drinking juice with a straw instead of directly through lips.
This means even if someone is monitoring, he’ll only able to see the connection between you and the VPN, not the webpage you are visiting.
Paid VPNs are fast and secured. Some of the paid VPNs use 256-bit encryption that is used by banks. And this can be very useful in improving smartphone security
#11. Turn Off Bluetooth while not in Use
Bluetooth has a range of 100 meters and very useful in making a short-range network connection. We share files, connect Bluetooth speakers and much more.
But if you don’t use it carefully, hackers may use it to drive malware to your smartphone and create problems for your smartphone security.
And so, I would recommend you to turn off while it is not in use and even it is in use keep it Undiscoverable. So that no one can make a connection with your device unknowingly.
And if you forget to turn off and get some suspicious pop-up, just reject it.
#12. Use SIM-Lock
You have a strong Screen lock. Do you think it is enough for your Smart phone security?
Well, I don’t think so. Even if you have Screen Lock but you should keep it in mind that screen lock doesn’t secure SIM card from being removed.
What if someone removes your SIM card and then use it in his/her phone. One can ruin your life just with a SIM card. Attacker or hacker can get access to your social media accounts by changing passwords through OTP. The worst thing that can happen is S(he) can steal your bank login details through it.
So, to avoid these things please use SIM card Lock to ensure that no one can use it without your permission.
#13. Enable Remote Control
We should always be prepared for the worst. And the worst thing that can happen to your phone is losing it. Because if someone tries to hack your phone then you have control over it and can recover from it with time.
But, what would you do if someone steals your phone?
Well, you can enable Remote control on your phone so that if you lose it, you can find the location of the phone and wipe out the phone using the Internet.
The second thing that you can do is enabling the Automatic factory reset your phone after a certain number of wrong tries.
So, these are some security tips to improve smartphone security without antivirus. If you follow these points then you would never need an Antivirus for your mobile phone.
Android is capable to secure itself and even if you use an antivirus but don’t follow security tips then you antivirus also won’t help you.
So, tell me were you using antivirus? And do you still want to use it after reading this? If you have any query or suggestion then please write in comments.
