+Our last video series was about data structures. We looked at the most common data structures, their use cases, pros and cons, and the different operations you could perform on each data structure.
+
+Today, we are kicking off a similar series for Authentication strategies where we will discuss everything you need to know about authentication and authentication strategies.
+
+In this guide today will be talking about what authentication is, and we will cover some terminology that will help us later in the series. You can watch the video below or continue reading this guide.
+
+<iframe src="https://www.youtube.com/embed/Mcyt9SrZT6g" title="Basics of Authentication" />
+
+## What is Authentication?
+
+Authentication is the process of verifying someone's identity. A real-world example of that would be when you board a plane, the airline worker checks your passport to verify your identity, so the airport worker authenticates you.
+
+If we talk about computers, when you log in to any website, you usually authenticate yourself by entering your username and password, which is then checked by the website to ensure that you are who you claim to be. There are two things you should keep in mind:
+
+- Authentication is not only for the persons
+- And username and password are not the only way to authenticate.
+
+Some other examples are:
+
+- When you open a website in the browser. If the website uses HTTP, TLS is used to authenticate the server and avoid the fake loading of websites.
+
+- There might be server-to-server communication on the website. The server may need to authenticate the incoming request to avoid malicious usage.
+
+## How does Authentication Work?
+
+On a high level, we have the following factors used for authentication.
+
+- **Username and Password**
+- **Security Codes, Pin Codes, or Security Questions** — An example would be the pin code you enter at an ATM to withdraw cash.
+- **Hard Tokens and Soft Tokens** — Hard tokens are the special hardware devices that you attach to your device to authenticate yourself. Soft tokens, unlike hard tokens, don't have any authentication-specific device; we must verify the possession of a device that was used to set up the identity. For example, you may receive an OTP to log in to your account on a website.
+- **Biometric Authentication** — In biometric authentication, we authenticate using biometrics such as iris, facial, or voice recognition.
+
+We can categorize the factors above into three different types.
+
+- Username / Password and Security codes rely on the person's knowledge: we can group them under the **Knowledge Factor**.
+
+- In hard and soft tokens, we authenticate by checking the possession of hardware, so this would be a **Possession Factor**.
+
+- And in biometrics, we test the person's inherent qualities, i.e., iris, face, or voice, so this would be a **Qualities** factor.
+
+This brings us to our next topic: Multi-factor Authentication and Two-Factor Authentication.
+
+## Multifactor Authentication
+
+Multifactor authentication is the type of authentication in which we rely on more than one factor to authenticate a user.
+
+For example, if we pick up username/password from the **knowledge factor**. And we pick soft tokens from the **possession factor**, and we say that for a user to authenticate, they must enter their credentials and an OTP, which will be sent to their mobile phone, so this would be an example of multifactor authentication.
+
+In multifactor authentication, since we rely on more than one factor, this way of authentication is much more secure than single-factor authentication.
+
+One important thing to note here is that the factors you pick for authentication, they must differ. So, for example, if we pick up a username/password and security question or security codes, it is still not true multifactor authentication because we still rely on the knowledge factor. The factors have to be different from each other.
+
+### Two-Factor Authentication
+
+Two-factor authentication is similar to multifactor authentication. The only difference is that there are precisely two factors in 2FA. In MFA, we can have 2, 3, 4, or any authentication factors; 2FA has exactly two factors. We can say that 2FA is always MFA, because there are more than one factors. MFA is not always 2FA because there may be more than two factors involved.
+
+Next we have the difference between authentication and authorization. This comes up a lot in the interviews, and beginners often confuse them.
+
+### What is Authentication
+Authentication is the process of verifying the identity. For example, when you enter your credentials at a login screen, the application here identifies you through your credentials. So this is what the authentication is, the process of verifying the identity.
+
+In case of an authentication failure, for example, if you enter an invalid username and password, the HTTP response code is "Unauthorized" 401.
+
+### What is Authorization
+
+Authorization is the process of checking permission. Once the user has logged in, i.e., the user has been authenticated, the process of reviewing the permission to see if the user can perform the relevant operation or not is called authorization.
+
+And in case of authorization failure, i.e., if the user tries to perform an operation they are not allowed to perform, the HTTP response code is forbidden 403.
+
+## Authentication Strategies
+
+Given below is the list of common authentication strategies:
+
+- Basics of Authentication
+- Session Based Authentication
+- Token-Based Authentication
+- JWT Authentication
+- OAuth - Open Authorization
+- Single Sign On (SSO)
+
+In this series of illustrated videos and textual guides, we will be going through each of the strategies discussing what they are, how they are implemented, the pros and cons and so on.
+
+So stay tuned, and I will see you in the next one.

+DNS or Domain Name System is one of the fundamental blocks of the internet. As a developer, you should have at-least the basic understanding of how it works. This article is a brief introduction to what is DNS and how it works.
+
+DNS at its simplest is like a phonebook on your mobile phone. Whenever you have to call one of your contacts, you can either dial their number from your memory or use their name which will then be used by your mobile phone to search their number in your phone book to call them. Every time you make a new friend, or your existing friend gets a mobile phone, you have to memorize their phone number or save it in your phonebook to be able to call them later on. DNS or Domain Name System, in a similar fashion, is a mechanism that allows you to browse websites on the internet. Just like your mobile phone does not know how to call without knowing the phone number, your browser does not know how to open a website just by the domain name; it needs to know the IP Address for the website to open. You can either type the IP Address to open, or provide the domain name and press enter which will then be used by your browser to find the IP address by going through several hoops. The picture below is the illustration of how your browser finds a website on the internet.

 Around 10 years ago, Jeff Atwood (the founder of stackoverflow) made a case that JavaScript is going to be the future and he coined the “Atwood Law” which states that *Any application that can be written in JavaScript will eventually be written in JavaScript*. Fast-forward to today, 10 years later, if you look at it it rings truer than ever. JavaScript is continuing to gain more and more adoption.

 ### Step 1
 When the browser first requests the server, the server tries to check the availability of the `Authorization` header in the request. Because it is the first request, no `Authorization` header is found in the request. So the server responds with the `401 Unauthorized` response code and also sends the `WWW-Authenticate` header with the value set to `Basic`, which tells the browser that it needs to trigger the basic authentication flow.

 As users, we easily get frustrated by the buffering of videos, the images that take seconds to load, and pages that got stuck because the content is being loaded. Loading the resources from some cache is much faster than fetching the same from the originating server. It reduces latency, speeds up the loading of resources, decreases the load on the server, cuts down the bandwidth costs etc.

Also, apart from stream ID being unique, it is worth mentioning that, any request initiated by client uses odd numbers and the response from server has even numbers stream IDs.

 I have been working on redoing the [roadmaps](https://roadmap.sh) – splitting the skillset based on the seniority levels to make them easier to follow and not scare the new developers away. Since the roadmaps are going to be just about the technical knowledge, I thought it would be a good idea to reiterate and have an article on what I think of different seniority roles.
 
 I have seen many organizations decide the seniority of developers by giving more significance to the years of experience than they should. I have seen developers labeled "Junior" doing the work of Senior Developers and I have seen "Lead" developers who weren't even qualified to be called "Senior". The seniority of a developer cannot just be decided by their age, years of experience or technical knowledge that they have got. There are other factors in play here -- their perception of work, how they interact with their peers and how they approach problems. We discuss these three key factors in detail for each of the seniority levels below.

It replaces the source IP address of the web request with the proxy server's IP address and then forwards it to the web server. The web server is unaware of the client, it only sees the proxy server.    
+
+![Proxy Server Description](/guides/proxy/proxy-example.png)    
+> NOTE: This is not an accurate description but rather just an illustration.    
+
+Proxy servers serve as a single point of control making it easier to enforce security policies. It also provides caching mechanism which stores the requested web pages on the proxy server to improve performance. If the requested web-page is available in cache memory then instead of forwarding the request to the web-server it will send the cached webpage back to the client. This **saves big companies thousands of dollars** by reducing the load on their servers as their website is visited by millions of users every day.

+## Forward Proxy Server    
+
+A forward proxy is generally implemented on the client side and **sits in front of multiple clients** or client sources. Forward proxy servers are mainly used by companies to **manage internet usage** of their employees and **restrict content**. It is also used as a **firewall** to secure the company's network by blocking any request which would pose threat to the companies's network. Proxy servers are also used to **bypass geo-restriction** and browse content that might be blocked in the user's country. It enables users to **browse anonymously**, as the proxy server masks their details from the website's servers.

+
+## Reverse Proxy Server    
+
+Reverse proxy servers are implemented on the **server side** instead of the client side. It **sits in front of multiple webservers** and manages the incoming requests by forwarding them to the web servers. It provides anonymity for the **back-end web servers and not the client**. Reverse proxy servers are generally used to perform tasks such as **authentication, content caching, and encryption/decryption** on behalf of the web server. These tasks would **hog CPU cycles** on the web server and degrade the performance of the website by introducing a high amount of delay in loading the webpage. Reverse proxies are also used as **load balancers** to distribute the incoming traffic efficiently among the web servers but it is **not optimized** for this task. In essence, a reverse proxy server is a gateway to a web-server or group of web-servers.

+
+## Summary   
+
+A proxy server acts as a gateway between client *(you)* and the internet and separates end-users from the websites you browse. ***The position of the proxy server on the network determines whether it is a forward or a reverse proxy server***.    A Forward proxy is implemented on the client side and **sits in front of multiple clients** or client sources and forwards requests to the web server. Reverse proxy servers are implemented on the **server side** it **sits in front of multiple webservers** and manages the incoming requests by forwarding them to the web servers. 
+
+If all this was too much to take in, I have a simple analogy for you.    
+
+At a restaurant, the waiter/waitress takes your order and gives it to the kitchen head chef. The head chef then calls out the order and assigns tasks to everyone in the kitchen.    
+
+In this analogy: 
+
+* You are the client
+* Your order is the web request
+* Waiter/Waitress is your forward proxy server
+* Kitchen head chef is the reverse proxy server
+* Other chefs working in the kitchen are the web servers

+# Threads and Concurrency
+
+A thread is an execution context in which the instructions to the CPU can be scheduled and executed independently of the parent process. Concurrency is the concept of multiple threads in a shared memory space being computed simultaneously (or intermittently executed in succession to provide that illusion). Concurrency allows multiple processes to execute at once and can apply to programming languages as well as operating systems.

 BitTorrent is a protocol for downloading and distributing files across the Internet. In contrast with the traditional client/server relationship, in which downloaders connect to a central server (for example: watching a movie on Netflix, or loading the web page you're reading now), participants in the BitTorrent network, called **peers**, download pieces of files from *each other*—this is what makes it a **peer-to-peer** protocol. In this article we will investigate how this works, and build our own client that can find peers and exchange data between them.
