Understanding HTTP

HTTP stands for HyperText Transfer Protocol. It is the foundation of any data exchange on the Web and is a protocol used for transmitting hypertext. HTTP allows for the fetching of resources, such as HTML documents, and it is the protocol that makes the web work.

When you enter a URL in your browser, it starts with “http://”, which tells the browser to use HTTP to communicate with the web server hosting the website. However, HTTP has a significant drawback: it transmits data in plain text. This means that any data exchanged between the browser and the server can be intercepted and read by anyone who has access to the data stream.

Additionally, HTTP uses a system of status codes to indicate the status of requests made by the client to the server. These HTTP status codes are essential for understanding how web interactions are processed. For example, a “200 OK” status means the request was successful, a “404 Not Found” indicates a missing resource, and a “500 Internal Server Error” points to a problem on the server side.

What is HTTPS?

HTTPS stands for HyperText Transfer Protocol Secure. It is an extension of HTTP and uses a secure connection to encrypt the data being transferred between the browser and the server. The secure connection is established using an SSL (Secure Sockets Layer) or TLS (Transport Layer Security) protocol.

When a URL starts with “https://“, it indicates that the website is using HTTPS, and any data exchanged is encrypted. This encryption ensures that even if the data is intercepted, it cannot be read without the decryption key, providing a higher level of security.

HTTP vs HTTPS: Key Differences

Data Encryption

• HTTP: Transmits data in plain text, making it vulnerable to interception and eavesdropping. Anyone with access to the data stream can read the information being exchanged, which poses a significant security risk.
• HTTPS: Encrypts data, ensuring that it remains confidential and secure during transmission. Even if the data is intercepted, it cannot be read without the decryption key. This encryption is vital for protecting sensitive information such as login credentials, payment details, and personal data.

Security

• HTTP: Does not provide any security features. Data can be easily intercepted and manipulated, leading to potential security breaches. This lack of security makes HTTP unsuitable for websites that handle sensitive information.
• HTTPS: Provides data integrity and authenticity. It ensures that the data sent and received has not been tampered with and that the website is legitimate. This level of security is crucial for maintaining user trust and protecting against various cyber threats, including HTTP flood attacks.

SEO Benefits

• HTTP: Websites using HTTP do not receive any special ranking benefits from search engines. In fact, search engines may penalize HTTP sites by ranking them lower in search results.
• HTTPS: Preferred by search engines, improving rankings and visibility. Google and other search engines prioritize HTTPS websites, which can lead to better search engine rankings and increased traffic.

Trust and Credibility

• HTTP: Users may see warnings in their browsers indicating that the connection is not secure. These warnings can deter users from visiting the site or entering personal information.
• HTTPS: Websites using HTTPS display a padlock icon in the browser’s address bar, instilling trust and confidence in users. This visual cue reassures users that their data is secure, encouraging them to interact with the website.

Performance

• HTTP: Generally faster because it does not need to establish a secure connection. However, this speed comes at the cost of security.
• HTTPS: Slightly slower due to the encryption/decryption process, but advancements in technology have minimized this difference. Modern implementations of HTTPS are highly optimized, resulting in negligible performance impacts.

Why to Choose HTTPS Over HTTP?

Protecting Sensitive Information

HTTPS is essential for safeguarding sensitive data such as login credentials, payment details, and personal information. Without encryption, this data is vulnerable to theft. HTTPS ensures that any data exchanged between the user and the website is encrypted and secure from eavesdroppers. This is particularly important for e-commerce sites, online banking, and any platform requiring user authentication. Similarly, for transferring files, secure versions of FTP, like FTPS or SFTP, provide encryption to protect data during transit.

Enhancing User Trust

Users are more likely to trust websites that display a secure connection icon (padlock). This trust is crucial for e-commerce sites and any platform requiring user interaction. When users see the padlock icon, they know that their data is being protected, which increases their confidence in the website. This trust can lead to higher engagement, lower bounce rates, and increased conversions.

Complying with Regulations

Many data protection laws, like GDPR, mandate the use of HTTPS to protect user data. Non-compliance can result in hefty fines and damage to the organization’s reputation. By implementing HTTPS, businesses can ensure they are meeting regulatory requirements and protecting user data from potential breaches.

Additional Benefits

Using HTTPS can also enable the use of newer web technologies that require secure connections, such as HTTP/2 and Progressive Web Apps (PWAs). These technologies can further enhance website performance and user experience. For instance, HTTP/2 can significantly improve loading times by allowing multiple requests to be sent simultaneously over a single connection.

The role of SSL Certificates

SSL certificates are digital certificates that authenticate a website’s identity and enable an encrypted connection. They are critical for implementing HTTPS. SSL certificates are issued by trusted Certificate Authorities (CAs) and come in various types, including Domain Validation (DV), Organization Validation (OV), and Extended Validation (EV).

Using ClouDNS SSL certificates, website owners can easily secure their sites, ensuring data privacy and boosting user confidence. ClouDNS offers a variety of SSL certificates, including Positive SSL, Positive SSL Wildcard, and EV SSL, to meet different needs. These certificates not only provide robust encryption but also display visual security indicators like the padlock icon and, for EV SSL, the organization’s name in the address bar, enhancing trust and credibility.

Additionally, services like HTTP/HTTPS monitoring help maintain the site’s security and performance by alerting owners to potential issues. Monitoring tools can detect anomalies in traffic patterns, identify potential threats, and ensure that SSL certificates are properly configured and up-to-date. By regularly monitoring HTTP and HTTPS traffic, website owners can proactively address security issues and maintain optimal performance.

Understanding SSL Certificates

SSL, or Secure Socket Layer, is a cryptographic protocol that provides secure communication over a computer network. SSL certificates are digital certificates that authenticate the identity of a website and encrypt the data transmitted between the user’s browser and the website’s server. They prevent unauthorized access and safeguard sensitive information such as login credentials, personal details, and financial transactions.

SSL certificates employ public key infrastructure (PKI) to authenticate the identity of the server and establish a secure channel for data exchange. When a website is secured with SSL, users can trust that their data is protected from theft and manipulation.

SSL certificates serve multiple purposes, including authentication, data integrity, and encryption. Authentication ensures that users are connecting to the intended website, while data integrity prevents information from being modified during transmission. Encryption, the primary function of SSL certificates, secures the data by converting it into a code that can only be decrypted with the corresponding decryption key.

What is SSL Certificate Monitoring?

SSL certificate monitoring is the proactive process of examining the status, validity and reliability of SSL certificates. As certificates have expiration dates, monitoring ensures that these certificates remain valid and do not expire, thereby preventing potential security vulnerabilities. Monitoring SSL certificates is essential to avoid security breaches, maintain trust with users, and comply with industry regulations.

The process involves regular checks that are necessary to verify that a server’s SSL certificate is properly installed and operational for a specific hostname. There are customization options available that allow the user to set the hostname, port, and timeout for the check.

How does SSL certificate monitoring work?

SSL certificate monitoring involves regularly checking and verifying the status of SSL/TLS certificates installed on a server. The process typically includes the following steps:

1. Hostname Verification: The monitoring system sends a request to the server, specifying a hostname. This is usually the domain name for which the SSL certificate is issued.
2. SSL Handshake: The server responds by presenting its SSL certificate during the SSL handshake process. This certificate contains information about the certificate issuer, the domain(s) it is valid for, and its expiration date.
3. Certificate Information Extraction: The monitoring system extracts information from the SSL certificate, such as the hostname for which the certificate is valid, the certificate issuer, and the expiration date.
4. Comparison: The extracted information is compared against the expected values. If the hostname specified in the monitoring check matches one of the hostnames listed in the SSL certificate and the certificate is still valid, the check is marked as UP. If the hostname is not found or the certificate is expired, the check is marked as DOWN.
5. Alerting: If the SSL certificate check determines that there is an issue, such as an expired certificate or mismatched hostname, an alert is triggered. This alert notifies administrators, allowing them to take corrective actions, such as renewing the certificate or fixing configuration issues.

Benefits of SSL certificate monitoring

SSL certificate monitoring offers several benefits to ensure the security and proper functioning of a website or online service. Here are some key advantages:

What is an SSL certificate? 

The letters SSL significate Secure Socket Layer. It is a specific cryptographic protocol that is used to secure communication. All the passing data gets encrypted. That encryption can be up to 256-bit for excellent protection. 

The idea is not to have sensitive data exposed in public. The SSL uses two keys, public and private, to verify the information. 

The OV and DV certificates

A domain-validated certificate is a popular choice, and it outnumbers the rest. It is the cheapest, and it validated only the domain name. The certification authority (CA) that issues it checks your e-mail and the one listed on the WHOIS record. After the verification, the CA provides a verification file that the owner can put on their site. 

The organization validated one has extra steps for verification. It requires business data such as the name, address, telephone number, and that gives additional trust for the consumers. It is often used by government organizations. 

The EV certificate

The extended validation is the best way to show your visitors or users of your products that you and your site or application can be trusted. To get an EV SSL, there are more steps to be passed, but this will guarantee authenticity better. The goal of it is to give extra credentials to business organizations and to help end-users evade phishing attacks by clearly showing which site or application can be trusted. 

Who uses it?

Many big brands use this certificate to provide the maximum level of security for their users.

• Cover the government requirements. Many countries, including some US states, require an EV SSL for proceeding delicate data. 
• It is used for signing applications too. If you have it, your application won’t trigger the pop-up sign from Windows 10 when the user is trying to install it. Windows will know it is safe. 

Who should buy it?

It is for those of you that need the highest possible level of confidence for your visitors and users of your application. You can benefit from purchasing an EV SSL certificate . It is suitable for financial institutions, big e-commerce platforms, and application development, in any case where sensitive data is involved.

The post EV SSL, the Extended Validation Certificate that beats the rest appeared first on ClouDNS Blog.

What is an SSL Certificate?

SSL means secure socket layer, and it is a cryptographic protocol that provides secure communication between the web browser and the servers of the website. All data that passes is encrypted and private.

When you are getting an SSL certificate, you will need to add some information about your company. This information is then used to create two keys – a public key and private key. Be careful not to lose the private key, because your certificate can’t work without it.

SSL Handshake

When a client tries to connect to your secured site, your server sends your SSL certificate. The browser checks if it is valid, and if everything is okay it makes a symmetric key for the session, using the public key. The server then decrypts the symmetric key with its private key. In the end, the SSL Handshake process is completed, and both the client and the server can encrypt and decrypt data using the session key.

Why is it so important?

Better security means clients who are not afraid of buying. This will increase your sales and improve the confidence in your website. The clients can be sure that their private data such as bank account and what they bought won’t go into “bad hands.”

You will improve your SEO and your rank in Google search results. Since 2014 Google is giving better ranking in their search result to websites, who has an SSL certificate. Google is trying to push website owners to embrace this security measure to build a safer internet for all of us.

How to protect your website with an SSL Certificate?

The process of getting an SSL certificate is not hard. To do so, you will need to buy such a certificate and validate your domain with it. ClouDNS offers two choices:

Positive SSL– has a more attractive price and validates one domain.
