What Is VPN Internet Security

The Blind Post Office Analogy:

How secure is a VPN? | NordVPN

Imagine a post office that doesnt know your first or last names or address. The post person inside this office receives and sends letters containing only one piece of information about you your customers ID. The post office generated this ID especially for you and it keeps it confidential.

When you receive a letter, the post person identifies you using this ID and forwards the mail directly to you. All this happens through a super-secret pipe that connects your house and the office.

In the same way, you can ask this courier to send a letter to anyone in the world. The courier will take your letter, attach your customer ID to it, slap the post offices address on it, and ship it. As far as the receiver is concerned the letter came from the post office and not from you .

To protect the contents of the mail and your ID, these letters are translated into a language only you and the post person can understand. So even if anyone got hold of your mail they couldnt read it.

What Is A VPN Connection

A virtual private network gives you online privacy and anonymity by creating a private network from a public Internet connection. VPNs mask your Internet protocol address so your online actions are virtually untraceable. Most important, VPN services establish secure and encrypted connections, guaranteed to provide greater privacy than even a secured Wi-Fi hotspot.

Internet Safety Tips For Children

Children are spending more and more time online, and its important to talk to them about how to stay safe on the internet. Making sure that kids know what information to keep private online is essential, for example explaining why they need to keep their passwords private, and not give out personal information. Keeping the computer in a common area, where you can watch and monitor its use, can also be a useful way of ensuring children use the internet safely.

Many kids enjoy watching YouTube videos. So, to make this a safer experience, you can use YouTube parental controls. You may also want to use YouTubes dedicated app for children, YouTube Kids. This provides a more child-friendly interface, and videos on the app are reviewed by a combination of human moderators and automated filters to help ensure videos are appropriate for younger children.

Enable Multifactor Authentication Wherever You Can

Multifactor authentication is an authentication method that asks users to provide two or more verification methods to access an online account. For example, instead of simply asking for a username or password, multifactor authentication goes further by requesting additional information, such as:

  • An extra one-time password that the website’s authentication servers send to the user’s phone or email address.
  • Answers to personal security questions.
  • A fingerprint or other biometric information, such as voice or face recognition.

Multifactor authentication decreases the likelihood of a successful cyber-attack. To make your online accounts more secure, it is a good idea to implement multifactor authentication where possible. You can also consider using a third-party authenticator app, such as Google Authenticator and Authy, to help with internet security.

What Does It Mean When A VPN Service Talks About Simultaneous Connections


The term “simultaneous connections” generally refers to the number of devices that can be connected to the VPN service and talk to the internet at once. For example, when I was driving across the country and working in my hotel room at night, I often had both my MacBook Pro and iPad connected to the internet.

I used the MacBook Pro for writing, keeping the iPad open to do searches and find supporting information. Both of these were connected to the internet at one time. This was possible because the VPN service I was using allowed up to three connections to open at once.

This is also a good way to provide support for more than one family member on a single subscription. Generally, there’s no good reason for a VPN provider to allow less than two or three connections. If your provider only allows one, find another vendor. We gave extra points in our VPN directory to those vendors who allowed three or more connections.

What Does A Consumer VPN Service Do

A consumer VPN service is, fundamentally, a software-as-a-service offering. The VPN service provides a secure tunnel between your computing device and the provider’s data center.

This is important to understand. Consumer VPN services protect your transmission from your location to their location, not from your location to the destination application you’re using. If you think about it, this makes sense: A consumer VPN service is operated by a completely different company than, for example, Facebook or your bank.

The VPN service gives you an app that you run on your local device, which encrypts your data, and it travels in its encrypted form through a tunnel to the VPN service provider’s infrastructure. At that point, the data is decrypted and sent on its way.

Two things happen here: First, if you’re using an https connection, your data is encrypted by your browser and then by your VPN app. Your data is decrypted only once at the VPN data centre, leaving the original encryption provided by the browser intact. That encrypted data then goes on to the destination application, like your bank.

Cryptographic Algorithms For Ipsec

IPSec relies on secure algorithms that conform to confidentiality, integrity, and authenticity.

They include:

  • Authentication algorithms such as RSA, PSK, and Elliptic Curve cryptography.
  • Symmetric encryption algorithms such as AES-CBC and GCM, HMAC-SHA, TripleDES, and ChaCha20-Poly1305.
  • Key exchange algorithms such as Elliptic Curve Diffie-Hellman and the Diffie-Hellman key exchange.

Is VPN Encryption Useful

VPNs for Data Protection and Internet Security | ExpressVPN Review

Yes and no. If youre visiting dirty websites it pays to double wrap. On the other hand, the majority of the internet, upwards of 90%, is already encrypted with HTTPS. The S stands for secure. This protocol uses chains of certificate authorities to ensure that the server youre talking to is legit and all your information is encrypted.

If you’re frequenting dodgy unencrypted websites there are advantages to an additional layer of encryption. Everything you send over unencrypted HTTP is sent as clear text and there are free tools that are publicly available that anyone can use to eavesdrop on your conversation.

How To Install A VPN Connection On Your Smartphone

As already mentioned, there are also VPN connections for Android smartphones and iPhones. Fortunately, smartphone VPN services are easy to use and generally include the following:

  • The installation process usually only downloads one app from the iOS App Store or Google Play Store. Although free VPN providers exist, its wise to choose a professional provider when it comes to security.
  • The setup is extremely user-friendly, as the default settings are already mostly designed for the average smartphone user. Simply log in with your account. Most apps will then guide you through the key functions of the VPN services.
  • Switching on the VPN literally works like a light switch for many VPN apps. You will probably find the option directly on the home screen.
  • Server switching is usually done manually if you want to fake your location. Simply select the desired country from the offer.
  • Advanced setup is available for users requiring a higher degree of data protection. Depending on your VPN, you can also select other protocols for your encryption method. Diagnostics and other functions may also be available in your app. Before you subscribe, learn about these features to find the right VPN for your needs.
  • In order to surf the internet safely from now on, all you have to do is first activate the VPN connection through the app.

How Does A VPN Work

When you sign up with a VPN provider, you first log onto that service before you connect to the internet. Once you are connected, others cant see your activity. Your VPN provider will encrypt your data, scrambling it so that hackers, government agencies, and businesses can’t see what websites you visit, messages you send, social media sites you use, or files you download.

Things To Remember When Using A VPN

A VPN will provide added security, but there are few things to keep in mind for extra protection. Never log into a sensitive account when you are not using VPN. In fact, leaving your VPN on at all times will ensure you are protected, especially when logging on using public Wi-Fi.

You should also choose a provider that lets you use multi-factor authentication to secure your VPN account. Multi-factor means you need more than just a password to confirm your identity, such as an additional code that is sent to you by text message or an app that creates a single-use login code.

Adaptable To Numerous Smart Devices

VPN Security: Everything You Need to Know About a VPN

While many of us may first try a VPN on a company-loaned laptop, many VPN services also protect other smart devices such as your phones, tablets and desktop computers. Each VPN company may offer slightly different protection plans and have different capacities to protect different devices, but many providers offer plans that help keep you safe on multiple devices.

Do You Need A VPN At Home

In truth, the answer to the question of whether you “need” a VPN in your house is going to come down to your own preferences. There are lots of good reasons why a home VPN might be a valuable addition to your security and privacy arsenal, but what’s most important is whether you will use it. If you find yourself too frustrated with reduced internet speeds, or juggling streaming devices, don’t use a VPN at home. An unused tool isn’t useful to anyone.

The decision by Congress that allows ISPs to sell anonymized data about their customers is a huge motivator for VPN use. It’s why we recommend keeping your VPN switched on as often as possible, even at home. Note, though, that we also recommend switching it off when you need to, for example, cast content to your TV. Security is important, but so is Star Trek.

Avira Prime Fast Virus Scans & Secure Browsing

Avira Prime has one of the best antivirus engines around it runs entirely in the cloud, so its fast, lightweight, and doesnt cause lags or slowdown.

During my tests, Aviras antivirus engine identified all of the malware samples I placed on my computer, and the real-time protection feature blocked all of the malware files I tried running.

Avira also has an excellent Safe Shopping browser extension which identified and blocked more phishing sites in my tests than most competitors. The extension also blocks browser tracking, preventing companies from tracking your online activity and delivering ads based on your browsing habits. Another cool thing about this extension is that it helps you find the best deals online.

Avira comes with an excellent VPN as well its secure, fast, and very easy to use. I was able to browse the web, stream video, and download files with minimal or no speed loss, which is pretty great for a bundled VPN.

However, one area where Avira could do better is parental controls. The Prime package doesnt include parental controls, though Avira does offer free parental controls named Family Protection Suite for Windows, which you can download separately. Compared to Norton and Bitdefender, however, its offering is pretty limited.

Priced at CA$68.00 / year, Avira Prime is the companys best internet security suite, and it covers up to 5 devices across all operating systems .

Access To Any Content In Any Place

While Hulu may frown upon your use of a VPN to stream the latest Criminal Minds episode in a country where the content isnt offered, this VPN usage is not illegal , and it helps provide a useful workaround to content restrictions.

VPNs spoof your location, making it seem as if you are browsing from another place. That means you can get your Criminal Minds fix even if its not available locally.

How Do I Choose A VPN

VPN Explained: What is a VPN? | NordVPN

The best VPNs secure your internet connection with reliable encryption, connect you to VPN servers with leading protocols, and provide you with stable and speedy service. Heres everything you need to know when considering how to choose a VPN:

  • Premium service: A leading premium VPN will offer the security, stability, privacy, and speed youre looking for. Many free VPN services simply cannot compete you can expect ads, unreliable connections, or weaker security. Your free VPN provider may also collect and sell your personal data.

  • Server quantity and locations: The more servers a VPN provider has, the better they can spread their users out, giving everyone a faster experience. Look for a VPN that ensures a stable and fast connection. And if you need an IP address in a specific country, make sure your VPN provider has servers there.

  • By grouping multiple users under a single shared IP address, its more difficult to identify the actions of any individual user. Find a VPN that gives you this additional layer of protection.

  • No Logs: VPNs with explicit no-logging policies wont keep any data about you they wont record what you do while connected to their VPNs or track when you connect or for how long. The only information theyll have on you is your IP address and the IP address of the server you connected to.

    Some providers claim to be no-log VPNs while actually tracking your use read your privacy policy carefully.

    A Guide To VPN: What Is Virtual Private Network

    Although most of us do not technically know what VPN is, we have an idea of what it does. Sometimes we use it to access blocked content, sometimes to do our work remotely by establishing a secure connection with our workplace.

    Internet traffic is monitored by government agencies in every country in the world. It is observed that people tend to use VPNs to protect their online privacy.

    The prohibition of access to resources due to the oppressive and prohibitive attitudes of some countries and the fact that users turn to VPN in order to overcome these prohibitions, VPN usage has increased significantly.

    The purpose of this article will be to cover what you need to know about what a VPN is and its benefits, theoretically and practically.

    Using A Corporate VPN In Windows

    Connecting to a VPN is fairly simple. In Windows, press the Windows key, type VPN, and click the Set up a virtual private network connection option. Use the wizard to enter the address and login credentials of the VPN service you want to use. You can then connect to and disconnect from VPNs using the network icon in the system tray the same one where you manage the Wi-Fi networks youre connected to.

    The Complications Of Privacy

    VPNs do have have practical drawbacks. Some sites and services look at VPN traffic as suspicious and won’t let you connect. That’s a real problem, especially when it’s your bank that blocks you. In situations like that, you can try a different VPN server, but you may have to wait until you can use a trusted network without a VPN.

    Chromecast and other streaming systems send data over your local network, but that’s a problem when you’re using a VPN. The same for printers, drives, or any other devices on your network. Those machines are looking for data from phones and computers on the same network, not from a distant VPN server. Some VPNs have options to allow local network traffic, or you could try using a VPN on your router, but the simplest solution might be to switch off your VPN.

    Do you like Netflix? That’s too bad because Netflix does not like VPNs. The problem is that Netflix has a complex global web of regional licensing arrangements, and they don’t want you using a VPN to access Netflix content that’s not available in your home country. Some VPN services, however, work hard to ensure their customers can still stream movies and TV shows. It’s something of a cat-and-mouse game, and a VPN that works with Netflix today might not work tomorrow.

    VPN Security: What You Need to Know to Stay Safe on the Web in 2020
