One of the best ways to protect yourself from these threats is to verify the authenticity of received emails. In this blog post, we'll discuss how you can do this on Gmail, one of the most popular email services in the world.

You can verify the authenticity of received emails by using both the browser and Gmail app.

Using web browser

To verify using a web browser you need to visit the official Gmail site (mail.google.com) and click on the email that you want to verify.

After that follow these steps:

Step 1: Check the Sender's Email Address

The first step in verifying the authenticity of an email is to check the sender's email address. This is the address that appears in the "From" field of the email. If you know the sender, make sure that the email address is the same as the one you have on file. If you don't know the sender or if the email address is unfamiliar, proceed with caution.

Cybercriminals often use email addresses that look similar to legitimate ones, so be sure to scrutinize the address carefully. Look for misspellings, extra characters, or unusual domain names. For example, instead of "paypal.com," a phishing email may come from "paypa1.com" or "paypal-security.com."

Step 2: Look for the "Mailed-By" and "Signed-By" Headers

Gmail provides additional information about the email's authenticity in the headers. To access the headers, open the email and click on the three dots in the top right corner of the email window. From the drop-down menu, select "Show original."

The headers will appear in a new window. Look for the "mailed-by" and "signed-by" headers. If the "mailed-by" and "signed-by" headers match the sender's domain, it's a good sign that the email is legitimate. If the headers show a different domain, be cautious and investigate further.

Step 3: Check the Email's DKIM Signature (Advance)

DKIM (DomainKeys Identified Mail) is a method for verifying the authenticity of an email message. It involves adding a digital signature to the email's header, which can be verified by the recipient's email server.

To check the email's DKIM signature on Gmail, open the email and click on the three dots in the top right corner of the email window. From the drop-down menu, select "Show original." Look for the "DKIM-Signature" header in the email's header. If the header is present and valid, it's a good sign that the email is legitimate.

DKIM (DomainKeys Identified Mail) is a method for verifying the authenticity of an email message. It involves adding a digital signature to the email's header, which can be verified by the recipient's email server.

To check the email's DKIM signature on Gmail, open the email and click on the three dots in the top right corner of the email window. From the drop-down menu, select "Show original." Look for the "DKIM-Signature" header in the email's header. If the header is present and valid, it's a good sign that the email is legitimate.

Now scroll down and try to search for "DKIM" and verify the result.

Step 4: Be Wary of Links and Attachments

Even if an email appears to be legitimate, be wary of links and attachments. Cybercriminals often use these to deliver malware or to trick you into providing sensitive information.

Before clicking on a link or downloading an attachment, hover your mouse over the link or attachment to see the URL or file name. If the link or attachment appears suspicious, don't click on it. Instead, contact the sender directly to verify the email's authenticity.

Step 5: Use Common Sense

Ultimately, the best defense against email scams is common sense. If an email seems too good to be true, it probably is. If you receive an unexpected email requesting sensitive information or asking you to take urgent action, be cautious. Verify the email's authenticity before taking any action.

Using the mobile app

It is recommanded to use the web browser insted of mobile app for verifying email's authenticity as there you will find more options.

Open your Gmail app and log in to your Google account. Then select the email that you want to verify the authenticity. After that click on the arrow icon to see detailed information and verify the email's from address. Then click on See security details and verify the "Mailed By" & "Signed By" domains.

Conclusion

Email security is an essential part of protecting your personal and professional information. By verifying the authenticity of received emails on Gmail, you can minimize the risk of falling prey to phishing scams, malware, and other types of cyber attacks. Remember to check the sender's email address, look for the "mailed-by" and "signed-by" headers, check the email's DKIM signature, be wary of links and attachments, and use common sense. By following these steps, you can help ensure safe communication on Gmail and protect yourself from cyber threats.

In conclusion, email security is everyone's responsibility. By taking the time to verify the authenticity of received emails, you can do your part to stay safe online. Don't let cybercriminals trick you into divulging sensitive information or downloading malware. Stay vigilant and stay safe.

Prerequisites

Before we get started, you'll need to make sure that you have the following:

• A server running Ubuntu 22.04

  (Get free $100 on your Digitalocean account to deploy your first server)

• A non-root user with sudo privileges

• A basic understanding of the Linux command line

Installation Steps

Step 1: SSH into your server

In order to perform the installation and configuration steps we need to log in or the server via ssh. For login, you will be needing a terminal or PowerShell. So please open it. There are 2 methods that we can use to log in to the server via ssh.

• Method 1: Via Password

  To log in using a password run this in your terminal/PowerShell

    ssh username@server_ip_address_here
  

  Then it will ask for your password please provide your password for the server.

• Method 2: Via SSH Key

  If you have set up an ssh key instead of a password for login then you need to run this in your terminal/PowerShell.

    # This is only for the 1st time
    chmod 400 /path/to/the/private_key.pem
  
    # This is for every time
    ssh -i "/path/to/the/private_key.pem" username@server_ip_address_here
  

Note: If you use different port than 22 Then you need to use the -p flag after the ssh commands.

For example:

# In this example we have used port 2022 as the ssh port
ssh username@server_ip_address_here -p2022

Step 2: Update Ubuntu

Before we begin, it is essential to make sure that your Ubuntu system is up-to-date. This can be done using the following commands:

sudo apt update
sudo apt upgrade

The first command updates the package list, and the second command upgrades any outdated packages to their latest version.

Step 2: Install Nginx

Next, we'll install Nginx by running the following command:

sudo apt install nginx

Once the installation is complete, you can start Nginx by running the following command:

sudo systemctl start nginx

You can also check the status of Nginx by running the following command:

sudo systemctl status nginx

Configuration Steps

Step 1: Configure Firewall

It's a good idea to configure your firewall to allow traffic on the ports that Nginx uses. By default, Nginx uses port 80 for HTTP traffic and port 443 for HTTPS traffic.

If you are running a firewall on your server, you will need to configure it to allow traffic to your web server. By default, Ubuntu 22.04 comes with a firewall called UFW (Uncomplicated Firewall). You can check if UFW is running using the following command:

sudo ufw status

Attention!!!

Please allow your ssh port before enabling the UFW or else you will lose access of your server.

# For default port
sudo ufw allow 22

# For custom port
sudo ufw allow custom_port_number_here

If UFW is not running, you can enable it using the following command:

sudo ufw enable

Now to allow traffic on nginx ports, you can run the following commands:

sudo ufw allow 'Nginx HTTP'
sudo ufw allow 'Nginx HTTPS'

Step 2: Create a Virtual Host

To serve web pages with Nginx, you'll need to create a virtual host. A virtual host is a configuration file that tells Nginx how to serve your website or web application.

To create a virtual host file, run the following command:

sudo nano /etc/nginx/sites-available/example.com

Replace example.com with your own domain name.

In the file, paste the following configuration:

server {
    listen 80;
    listen [::]:80;

    server_name example.com www.example.com;

    root /var/www/example.com/html;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
    }
}

This configuration tells Nginx to listen on port 80 and to serve web pages from the /var/www/example.com/html directory.

Once you've saved the configuration file, create a symbolic link from the sites-available directory to the sites-enabled directory by running the following command:

sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/

Finally, restart Nginx by running the following command:

sudo systemctl restart nginx

Conclusion

In this tutorial, I've shown you how to install and configure Nginx on Ubuntu 22.04. By following these steps, you should now have a working Nginx server that can serve web pages and handle incoming traffic. If you run into any issues, feel free to leave a comment and I'll try to help you.

    # This is only for the 1st time
    chmod 400 /path/to/the/private_key.pem
  
    # This is for every time
    ssh -i "/path/to/the/private_key.pem" username@server_ip_address_here
  

Note: If you use different port than 22 Then you need to use the -p flag after the ssh commands.

For example:

# In this example I have used port 2022 as the ssh port
ssh username@server_ip_address_here -p2022

Step 2: Update Ubuntu

Before we begin, it is essential to make sure that your Ubuntu system is up-to-date. This can be done using the following commands:

sudo apt update
sudo apt upgrade

The first command updates the package list, and the second command upgrades any outdated packages to their latest version.

Step 3: Install Apache 2

Now that we have updated Ubuntu, it's time to install Apache 2. This can be done using the following command:

sudo apt install apache2

Once the installation is complete, you can verify that Apache 2 is running by entering your server's IP address in your web browser. You should see the Apache 2 default page.

Configuration Steps

Step 1: Configure Apache 2

Now that we have installed Apache 2, it's time to configure it. The Apache configuration file is located at /etc/apache2/apache2.conf. You can open it using a text editor like nano or vim:

sudo nano /etc/apache2/apache2.conf

Here are some key configurations to pay attention to:

ServerName - This directive should be set to your server's domain name or IP address.

DocumentRoot - This directive sets the location of your website's files.

DirectoryIndex - This directive sets the default page that is served when a user visits your website. By default, Apache 2 serves index.html.

No changes are needed here. But still if you want you can change some options. Once you have made your changes, save the file and exit.

Step 2: Create a Virtual Host

If you want to host multiple websites on your server, you will need to create a virtual host. A virtual host allows Apache 2 to serve multiple websites on a single server. To create a virtual host, create a new file in the /etc/apache2/sites-available/ directory:

sudo nano /etc/apache2/sites-available/example.com.conf

Here is an example of a virtual host configuration:

<VirtualHost *:80>
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example.com/public_html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

In this example, I have created a virtual host for example.com. I have set the ServerName and ServerAlias directives to point to our website's domain name. The DocumentRoot directive sets the location of our website's files. Finally, the ErrorLog and CustomLog directives set the location of Apache 2's log files.

Once you have created your virtual host configuration, you will need to enable it using the following command:

sudo a2ensite example.com.conf

This command creates a symbolic link in the /etc/apache2/sites-enabled/ directory to your virtual host configuration.

Step 3: Restart Apache 2

Now that we have made our changes to the Apache 2 configuration, we need to restart the service for the changes to take effect. This can be done using the following command:

sudo systemctl restart apache2

This command restarts the Apache 2 service.

Step 4: Configure Firewall

If you are running a firewall on your server, you will need to configure it to allow traffic to your web server. By default, Ubuntu 22.04 comes with a firewall called UFW (Uncomplicated Firewall). You can check if UFW is running using the following command:

sudo ufw status

Attention!!!

Please allow your ssh port before enabling the UFW or else you will lose access of your server.

# For default port
sudo ufw allow 22

# For custom port
sudo ufw allow custom_port_number_here

If UFW is not running, you can enable it using the following command:

sudo ufw enable

To allow incoming HTTP traffic, you can run the following command:

sudo ufw allow http

To allow incoming HTTPS traffic, you can run the following command:

sudo ufw allow https

Step 5: Test Your Web Server

Now that you have installed and configured Apache 2, it's time to test your web server. Open your web browser and enter your server's IP address or domain name. You should see your website's default page or the page for the virtual host you created earlier.

Congratulations! You have successfully installed and configured Apache 2 on Ubuntu 22.04.
