by rahulsandal25x 28th March 2020

This article all about how to protect credit card or debit card detail on browsers like Firefox and Chrome on the Web or Windows 10. Many people have a concern about how to protect credit card or online detail from the hackers when we make payment online by the Browser like Chrome and Firefox. To know about how can make safe online payment? and credit card tips.

Know about the website or Website Reputation

When you buy or purchase something on the unknown or first time, then you have to check the status of the website. I will show you how to check Website Reputation or know about the website.

There are many ways to check the status of any website. There are many plugins available on the Chrome web store or Firefox or Microsoft Edge. Use one of them. Ther are WOT, Avast online security, Ghostery, etc.

if you install one of these plugins, it will warn you when you open a malicious website. Don’t open and do not a payment for these websites.

Check SSL certificate or check Lock security on Search war in any browser.

Check the SSL certificate of a website which you will pay. How to Check the SSL certificate of a website? Check the below images.

SSL certificate, SSL certificate of a website — SSL certificate of a website

Click on lock, if say Connection is secure then you will pay. If it will say, Connection is not secure then you have a risk. You may lose your credit card detail on the web. Also, your data on the browser can steal by hackers.

Don’t ignore this warning. In the future Chrome browser will block the website that has no SSL certificate.

Do not save Credit card detail on Autofill

When we made the payment online, often the chrome or Firefox browser save your credit card detail on the Password manager.

if anybody can know your password like your friend, they can steal your information from the browser.

nothing save on the web, hackers always find the way to steal the account detail specially Finacial detail. So they can steal from your browser.

Update your Browser before payment

Update everything like browser or install security patches on the operating system like android, windows 10 or MAC. Sometimes new operating system updates have bugs or technical errors. they help to breach our data by the hackers.

Do not install Cracked software

If you have a business or do online payment for your business then never use cracked software. When we install pirated software they also install malware on our system like Trojans, viruses.

Also, they can install malicious plugins in the browser. You have seen when we install software, they will install plugins in the browser without our permission

When we open the browser, the new homepage opens. This malicious software changes our homepage setting. They can be risky for our business so do not install cracked software.

Do not use Public WiFi

Public WiFi is always risky because we don’t know who is the actual provider of the Public WiFi service for us.

Hackers also set up a free Public WiFi network near Public Places like the name of shops, malls, coffee shops.

Why Public WiFi is not safe for payment

When we use the internet on Public wifi, our data goest to the WiFi Reuter. So Internet providers can see our data through their server. That’s why Public WiFi is not considered as Safe.

Use Trusted VPN

VPN service encrypted our data on any server. So nobody can steal our online detail. There are many VPN like Nord VPN, HotspoT Shiels, Avast Secure Line VPN, etc.

Add another layer of security

I am talking about Enabling a two-factor authentication like OTP with the help of Mobile number or Email Id.

While you allow a two-factor authentication code, you’re simply including one other step (comparable to being requested a safety query that only you’d know the reply to or sending a code by way of electronic mail or textual content message to your self as extra verification) in order that others trying to achieve entry to your account can’t.

Is it safe to pay by credit card online?

Yes, always use a credit card over Debit Card. If anybody can steal your money through a Credit card, it is the responsibility of the bank to provide security to you.

Credit card bills are paid only after the month if there is fraud with you then you can have a complaint in the bank. That means your money is safe.

How can you protect your credit card from hackers?

I explain everything about How can you protect your credit card from hackers? Read the above articles.

What is the safest way to pay online?

First, you have to know which method you will use for payment. Paypal or credit card is one of the safest methods for payment.
where you want to pay- Do not pay on the malicious website.

What is the safest method of payment?

I always considered Paypal for my purchase. If any fraud happens with me, Paypal provides protection against the fraud. After the inspection, Paypal returns the full amount.

what is ipv4 and ipv6 in computer networks

by rahulsandal25x 23rd March 2020

written by rahulsandal25x

The IP address allows various devices to communicate with each other via the internet. Every device has own IP address. An IP address like a home address that is unique for every device like a computer, mobiles, etc. IP4 and IP6 are both different terms, we will know about IPv4 vs IPv6 in this articles.

What’s IP?

An Internet Protocol address, also we are known as an IP address. It’s a numerical address like our home address that is assigned to each system related to a pc community which makes use of the IP address for communication. Every system has own unique IP address.

IP address act as an identity for every machine on a selected community. The IP address can also be known as IP quantity and web handle. Most networks mix IP address with a TCP (Transmission Management Protocol). It additionally permits creating a digital connection between a vacation spot and a supply.

What is IPv4?

IPv4 was the first version of IP or the internet protocol. It was deployed by ARPANET in 1983. Today every country and service used the IPv4 version. It is used to identify every device on any network using an internet protocol addressing system.

The IPv4 uses a 32-bit security address system that means 2^32 addresses which are more than 4 billion addresses. To date, it is considered the primary Internet Protocol and carries 94% of Internet traffic used IPv4 on the web.

Advantages of IPv4

Connectionless Protocol
IPv4 makes data to be secured with encryption
Permit making an easy digital communication layer over diversified gadgets
It requires much less reminiscence and ease of remembering addresses
Already supported protocol by thousands and thousands of gadgets
Gives video libraries and conferences

What is IPv6?

It was launched in 1994 which is a newer version of the IPv4. Many of the web services still use IPv4 over IPv6.

Each pc, cell phone, residence automation element, IoT sensor and every other gadget related to the Web wants a numerical IP tackle to speak between different units. The unique IP tackle scheme, referred to as IPv4, is working out of addresses as a result of its widespread utilization from the proliferation of so many related units.

Advantage of IPv6

Stateful and Stateless configuration
Help for the high quality of service (QoS)
A perfect protocol for neighboring node interplay
Simplified Network Configuration
Security – IPSec security, which gives confidentiality, authentication, and information integrity, into the IPv6.
Auto-configuration

ipv4 vs ipv6- Which is faster

I found the test on the Sucuri blog about the speed of the IP address.

chart_ipv4-vs-ipv6_tokyo — Source- https://blog.sucuri.net/

So in this test, we see IPv4 is faster than IPv6 according to the Sucuri Blog.

The Difference Between IPv4 vs IPv6?

IPv4 used a 32-bit method for its IP or Internet addresses. Where IPv6 used a 128-bit method for its IP address.

So 32-bit means it can provide support for 2^32 IP addresses is around 4.29 billion. That’s why most of the new services use IPv6 over IPv6.

IPv6 makes used 128-bit security of Web addresses.So it has 2^128 Web addresses=340,282,366,920,938,463,463,374,607,431,768,211,456. The number of IPv6 addresses is 1028 times bigger than IPv4 addresses. So there are greater than sufficient IPv6 addresses to permit Web gadgets to broaden for a really very long time.

IPv4 is using numeric addressing method whereas IPv6 is an alphanumeric addressing method. For Example, IPv4 is like 108.78.629.97 where IPv6 is like 2011:vg87:0000:0000:0000:ff00:0062:7572

Why new services Support IPv6? What are the benefits of IPv6?

It is the newer version of the IPv4 and new features introduced in the IPv6. Not only features, we know that every new version comes with Fixed errors and vulnerability than the previous version.

IPv6 has 128-bit features that’s mean more than 1028 times users used this Protocol than IPv4. It functions equally to IPv4 in that it offers the distinctive IP addresses essential for Web-enabled units to communicate.

More Benefits of IPv6

Auto-configuration
No more private address that colloid in IPv4
Better multicast routing
Simpler header format
Simplified, more efficient routing
No. of the header field is 8
Type of Addresses is Unicast, multicast, and anycast
In IPv6, the configuration is optional, depending upon on functions that perform by the device

How to Protect your IP address

Why we have to protect IP addresses on the internet? This is an interesting question about the security of the devices.

With the IP address, you can expose on the web and can be monitor on the internet by the hackers, even Government can spy of your activities.

So how you can protect your IP address

The answer is very Simple, VPN. VPN hides your location on the internet and provides you new IP address and also changes your server location.

How to disable IPv6 on Windows, Mac, and Linux

If your device has IPv6, or you can check the IP address by the various tools. After detecting your IP address, you can disable it by the various VPN services like Avast SecureLine VPN.

Here is the Full guide of disabling on Windows, Linux

IPv4 vs. IPv6: Which is more Security

IPv6 was build with extra security in mind. IP Safety (IPSec) is a collection of IETF security protocols for security, authentication, and information integrity, and it’s absolutely built-in into IPv6.

IPv6 is designed for end-to-end encryption. IPv6 comes with IPSec, IPv6 offers two security headers which utilized individually or collectively

IPv4 Security

IPv4 has been considerably up to date through the years, so the distinction between IPv4 and IPv6 security shouldn’t be extraordinary. The identical IPSec in IPv6 is now accessible for IPv4
