Top 10 preventive measures to safeguard Data security

1. Encrypt your data :

Data encryption is helpful to detect any virus or any malicious activity going on with your gadgets. It creates two factor authentication and ensures safety of data.

In google cloud, Cloud Storage always encrypts your data on the server side, before it is written to disk, at no additional charge. And in Google cloud, there are many ways to encrypt the data such as :

A. Through Default Google Encryption
B. Through Customer supplied encryption keys

2. Backup your data :

This is one of the important aspects that we forget in our day-to-day activities. If our Computer or smartphone seems to be infected through viruses or malware software then we reset it or do formatting of our computer. After doing that we realise that we hadn’t done backup of your data.

In order to backup data, you can use G suite tools such as Google drive, Google photos or you can save your data in external software.

By saving your data in those tools it will easily help you to maintain and store your data properly.

3. Anti-malware protection is a must :

Sometimes, we really don’t care that our files will be corrupted. With this, your technical gadgets are wholly impacted. Important data is harmed. In order to avoid it we always need to install anti-malware protection software. If possible, you can download an antivirus which protects your data from threats. Mcafee is a good example for Anti-virus

4. Make your old computers’ hard drives unreadable :

Ethical Hackers can easily identify your computer hard drives and they can easily hack your all information. It is important

5. Think before you click :

Sometimes we get messages or emails like “won 2 crores lottery or received award” etc. In such cases we should always be careful and think twice and thrice before clicking or responding to it. With just one click of the button, your data gets leaked and it leads to various severe problems like cyber crime.

6. Automate your software updates :

In order to ensure that you’re downloading the latest security updates from operating systems and other software, enable automatic updates. “Many software programs will automatically connect and update to defend against known risks.

7. Secure your wireless network at your home or business :

A valuable tip for both small business owners and individuals or families, it’s always recommended to secure your wireless network with a password. This prevents unauthorized individuals within proximity to hijack your wireless network. Even if they’re merely attempting to get free Wi-Fi access, you don’t want to inadvertently share private information with other people who are using your network without permission. “If you have a Wi-Fi network for your workplace, make sure it is secure, encrypted, and hidden. To hide your Wi-Fi network, set up your wireless access point or router so it does not broadcast the network name, known as the Service Set Identifier (SSID).

8. Turn off your computer :

When your work or online lectures are done, you need to shut down your computer. It is recommended that you do not keep the computer on stand-by or sleep mode. Also, make sure that computer is shut down properly. If we don’t follow these above points then viruses, malwares are easily entered and it can harm your data.

Use a Firewall :

Firewalls assist in blocking dangerous programs, viruses or spyware before they infiltrate your system. Various software companies offer firewall protection, but hardware-based firewalls, like those frequently built into network routers, provide a better level of security.

10. Don’t store passwords with your laptop or mobile device :

Sometimes we have a habit to store everything in our laptop or mobile device which results in data breach. Never store your password in any doc or files!!!
