  • SSL Certificate are Crucial for Boosting Search Engine Ranking

    SSL Certificate are Crucial for Boosting Search Engine Ranking

    SSL certificates are increasingly common as internet security is a major concern, especially for large internet companies like Google. Google blacklists over 10,000 websites every day, removing them from search results and cutting off the majority of visitors. This can damage not only your sales but also harm your reputation. Other than Google, no one really knows the specific criteria for search rankings or the reasons for a website being blacklisted.

    What is SSL Certificate?

    SSL certificates are indicated by a green padlock next to a URL and the green “https” at the start of the URL. These certificates encrypt data transmitted between servers and computers, often securing credit card information, login details, and data transfers. It’s important to note that SSL certificates protect visitors’s information, not the website itself. Clear indicators of an SSL certificate include a green padlock to the left of the URL and “https” at the beginning of the URL.

    What Does SSL Mean?

    SSL stands for “Secure Sockets Layer.” It is a certificate issued to a website by a trusted source, ensuring the website is protected by standard security technology.

    The certificate issuance establishes an encrypted link between the client and the webserver or browser, ensuring that all exchanged information remains secure and protected from theft or hacking.

    What is SSL Encryption?

    SSL encryption refers to the public concealment of all information and data transited on a website from a visitor to the website owner. This data could include login credentials, social security number, credit card number, medical records, property information, and financial information.

    Since all this data is highly personal and sensitive, the website has a responsibility to safeguard it at all costs from theft, leaks, or unauthorized access. This is achieved through SSL encryption, symbolized by the padlock icon and HTTPS in the address bar, giving users the assurance that their shared information will be kept confidential.

    How Does SSL Certificate Work?

    In simple terms, SSL certificates work by ensuring that data and information exchanged between the user and the website remain hidden from public view. SSL uses encryption algorithms to scramble the data during transmission, making it reach the website safely and securely, and impossible to be read by a third party.

    The whole process works in the following steps.

    1. A browser attempts to connect to the website secured with SSL.
    2. The browser demands identification from the website.
    3. The web server replies with a copy of its SSL certificate.
    4. The browser checks the information. If the information is correct, it authorizes the webserver.
    5. The web server returns a signed acknowledgment to begin the SSL encrypted process.
    6. Data encryption is shared between the browser and the web server.

       This process is also known as “SSL handshake.” This process takes seconds.

    When the process is complete, the website will display “HTTPS” in the URL. Additionally, a padlock icon will appear on the address bar, indicating a secure connection

    • A user can click on the padlock icon to access the following information
    • The domain name of the certificate holder
    • The individual, entity, or apparatus to which the certificate was issued
    • Certificate Authority name and digital sign
    • Sub-domains associated with SSL
    • Date of issuance
    •  Expiration date
    •  Public key
    •  Public key

    Types of SSL Certificates.

    An SSL certificate serves the purpose of providing security and encryption for websites. There are six different types of SSL certificates, and it’s important for website owners to understand each type in order to choose the most suitable and cost-effective certificate for their website.

    1. Extended Validation Certificate (EV SSL)

    This type of SSL certificate is the most expensive and highest-ranked. It is typically used by large-scale and high-profile websites that collect sensitive consumer information and use online payment methods. When installed, this SSL certificate displays a padlock, HTTPS, business name, and country name on the browser.

     Additionally, the website owner’s information is displayed on the address bar, making it easier for users to distinguish it from shady websites. To obtain an EV SSL, the website owner must undergo standardized identity verification to be legally authorized for exclusive domain rights.

    2. Organization Validated Certificate (OV SSL)

    Commercial and public-facing websites typically prioritize the confidentiality of their personal information. This type of SSL certificate is similar to EV SSL, but it undergoes the same validation process and displays the website owner’s information on the address bar. It is the second most costly SSL certificate.

    3. Domain Validated Certificate (DV SSL)

    The browser address bar only displays a padlock and HTTPS. This is usually seen on blogs and informational sites that do not collect payment information. This type of certification only requires confirmation from a domain owner through email or phone call, providing lower assurance and encryption.

    4. Wildcard SSL Certificates

    Wildcard SSL certificates secure the base domain and an unlimited number of subdomains with a single certificate. If you have multiple subdomains that require encryption, purchasing a wildcard SSL certificate is more cost-effective than buying individual SSL certificates for each one. Wildcard SSL certificates are identified by an asterisk (*) as part of the name, which represents all subdomains sharing the same main domain.

    5. Unified Communications Certificate (UCC)
     

    Unified Communications Certificates (UCCs) are also known as multi-domain certificates. They were initially created to secure Microsoft Exchange and Live Communications servers, but now they can be used by any website that needs to secure multiple domain names with a single SSL certificate.

    UCCs are organizationally validated and display a padlock in the browser. They can also function as EV SSL certificates, providing visitors with the highest level of encryption and displaying a green address bar.

    Why You Need an SSL Certificate

    New website owners may consider SSL certificates as optional. However, if you plan on scaling your website, it’s important to get an SSL certificate right after establishing your site, so that users trust your website from the beginning. Here are some reasons why your website should use an SSL certificate.

    Secured Date

    The primary purpose of an SSL certificate is to secure your website’s data and protect its users. It helps prevent attacks on your website’s security and authenticity, and it ensures that no one can create a fake website in your name or use your information for criminal activities.

    Encrypted Information

    Many websites require you to sign in using your email or phone number and input personal information such as credit card numbers to make a purchase. Some service-based sites may also ask for details related to your health, property, or finances for consultation purposes. It’s important to remember that this data is highly personal and should not be shared with anyone. The SSL certificate on the website encrypts this information, ensuring that it is secure between the user and the website owner. This means that if anyone tries to access your information from the site, they wouldn’t be able to.

    Displays Security

    When a website lacks SSL certification and doesn’t display the HTTPS tag, it may be labeled “not secure” by the browser. This can lead users to perceive the site as an “unknown source” with an “insecure connection,” prompting them to leave without making any purchases or downloads. On the other hand, a website with an SSL certificate will display a padlock icon and a “secure connection” message in the address bar, providing users with assurance that their web surfing is safe and secure.

     

    Conclusion

    SSL certificates are a must-have for protecting online transactions and user data. With Google’s strict security standards and undisclosed ranking criteria, having an SSL certificate is crucial for website owners. Understanding the different types of certificates allows informed decisions on security levels. Ultimately, SSL adoption is about building trust and ensuring online security.

    The platform facilitates the rapid and straightforward deployment of applications within a uniform environment, alleviating concerns about the intricacies of the infrastructure. Docker also offers an extensive array of tools and services for effectively managing and monitoring applications. Additionally, it provides features for constructing and sharing images collaboratively among developers. Recognized as an indispensable tool in modern software development, Docker is widely adopted by some of the world’s leading companies.

    This tutorial guides you through the installation and utilization of Docker Community Edition (CE) on Ubuntu 22.04 in Linux VPS Server.

    Requirements

    Familiarity with the Linux command line is essential. You need an Ubuntu 22.04 Linux VPS Server with a non-root user possessing sudo privileges. You can acquire an affordable and potent Ubuntu Linux VPS Server from our website. Refer to our “How to access your server using SSH” guide for instructions on accessing your server and establishing a sudo user.

    Updating Package Cache and Installing Necessary Packages

    Start by updating the packages in the package manager cache to the latest available versions using the following command:

     sudo apt update

    Next, install a few packages that will allow us to use apt with HTTPS in order to add the official docker repository and get the latest version of Docker. To do this, run the following command:

    sudo apt -y install apt-transport-https ca-certificates curl software-properties-common

    Installing Docker

    We will use the official Docker repository to install the latest version of Docker. First, add the GPG key for the official Docker repository to your system:

    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

    Next, add the official Docker repository to your APT sources:

    echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

    Update your package index:

    sudo apt update

    Now, with the repository added, install the docker-ce package, which is the Docker Community Edition package:

    sudo apt install docker-ce

    Once the installation finishes, check that Docker is running:

    sudo systemctl status docker

    You should receive output indicating that Docker is active and running, similar to the following:

    • docker.service – Docker Application Container Engine
    Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
     Active: active (running) since Sun 2022-12-18 13:50:49 UTC; 32s ago

     CGroup: /system.slice/docker.service
             └─323716 /usr/bin/dockerd -H fd://-containerd=/run/containerd/containerd.sock

    Using Docker

    With docker installed, you can now use it to manage Docker images.

    To see all available docker subcommands, run the following command:

    docker

    You should receive a list of docker subcommands and a brief description for each one.

    You can use the syntax docker COMMAND –help to get more information on a specific subcommand. For example, to get more information on the docker rm command, you can use the –help flag as follows:

    docker rm --help

    You should receive output similar to the following:

    Usage:  docker rm [OPTIONS] CONTAINER [CONTAINER...]
Remove one or more containers
Options:
 -f, --force     Force the removal of a running container (uses SIGKILL)
  -l, --link      Remove the specified link
  -v, --volumes   Remove anonymous volumes associated with the container

    To view general information on your Docker installation, use docker info like so:

    sudo docker info

    This will show you information on your Docker configuration and Linux VPS Server properties.

    Downloading a Docker Image from Docker Hub:

    It is a cloud-based service that provides a centralized repository for Docker images. It allows users to store, manage, and share Docker images with other users. It provides a secure and reliable way to share and store Docker images, which can be used to create and deploy applications. Docker Hub also provides a wide range of services, such as private repositories, automated builds, and integration with other services.

    To test whether you can access Docker Hub, run the hello-world image:

    sudo docker run hello-world

    You should receive an output that shows that your installation is working correctly:

    Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
2db29710123e: Pull complete 
Digest: sha256:c77be1d3a47d0caf71a82dd893ee61ce01f32fc758031a6ec4cf1389248bb833Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.

    You can use the docker search command to search for images hosted on Docker Hub like so:

    sudo docker search ubuntu

    Here, you search for the Linux VPS Server Ubuntu image. You should see a list of results like so:

    NAME                             DESCRIPTION                                     STARS     OFFICIAL   AUTOMATED

    Images that are officially maintained and supported are labeled as [OK] under the OFFICIAL column.

    In the results above, you see that ubuntu is the name of the official Ubuntu image. You can download it using the docker pull command like so:

    sudo docker pull ubuntu

    You should receive the following output:

    Using default tag: latest
latest: Pulling from library/ubuntu
6e3729cf69e0: Pull complete 
Digest: sha256:sha256:27cb6e6ccef575a4698b66f5de06c7ecd61589132d5a91d098f7f3f9285415a9
Status: Downloaded newer image for ubuntu:latest
docker.io/library/ubuntu:latest

    You can list the images you’ve downloaded so far using the following command:

    sudo docker images

    You should see ubuntu and hello-world like so:

    REPOSITORY    TAG       IMAGE ID       CREATED         SIZE
ubuntu        latest    6b7dfa7e8fdb   9 days ago      77.8MB
hello-world   latest    feb5d9fea6a5   15 months ago   13.3kB

    The reason the image hello-world was downloaded, is that the docker run command either runs a container using an image if it has been downloaded, or downloads the image and then runs a container using it.

    Running a Docker Container:

    Docker containers can be run to perform a task in an isolated environment, just like running the hello-world container performs the task of printing a message. However, containers can also be interactive.

    For example, you can run a container using the Ubuntu image you’ve downloaded previously with an interactive shell using the docker run, and then -it switches:

    sudo docker run -it ubuntu

    Your prompt should now be a root shell like so:

    root@242d22e1d9da:/#

    This is the root user of your Linux VPS Server Ubuntu container, and you can now manage it just like a virtual machine.

    With this shell prompt, you can run any command inside your Ubuntu container. For example, you can update the package index inside the container using apt update like so:

    root@242d22e1d9da:/# apt update

    You can also install any application or package using apt install. For example, you can install Python 3 like so:

    root@242d22e1d9da:/# apt install python3

    Once the installation finishes, you can run Python like so:

    root@242d22e1d9da:/# python3

    This should allow you to access the Python REPL inside your Ubuntu container:

    Python 3.10.6 (main, Nov 14 2022, 16:10:14) [GCC 11.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

    With this, you can run programs and modify your container in an environment that is isolated from the rest of your Linux VPS Server.

    Congratulations!
