Comparison of SSL vs TLS: CyberPanel Here For Security & Guide

The internet has been growing daily, and your need for vigorous security measures to protect data transmission is increasing. In earlier days, internet communications were open to eavesdropping and tampering. This fact promotes the need for encryption protocol development. SSL vs TLS is known as Secure Socket Layer and Transport Layer Security respectively. These have emerged as crucial technologies of the age for making online interactions secure. It ensures data confidentiality and integrity.

Historical Context

Let’s explore the historical backdrop of SSL vs TLS. So, SSL was developed by Netscape in the middle of 1900 to provide secure communications. It has been improved over time and SSL 3.0 has come into force. TLS appeared to the world in 1999 by the “Internet Engineering Task Force (IETF)” aiming at improving security features and mitigating lacunas of the former technology. 

Hundreds of service providers exist on the internet, but CyberPanel hits differently for you. Let’s dive into the stream of knowledge of SSL vs TLS with the individualistic approach of CyberPanel.

Encryption

It is the process of protecting data and information by converting it into that data which is only accessible to users having proper keys. There are two types of encryption which are described below.

Symmetric Encryption:

This type of encryption uses the same key for both encryption and decryption. It is highly recommendable for your servers because it is efficient and fast. Now explore some common symmetric encryption:

Advanced Encryption Standard (AES)

It is a widely used encryption standard well-known for its stability and speed.

Data Encryption Standard (DES)

It is an old method. It was a house with vulnerabilities and lackings so, it couldn’t stay longer.

Asymmetric Encryption:

This approach uses two keys: a public key to encrypt and a private key to decrypt. People always use this method to exchange keys. Here are some well-known asymmetric algorithms:

• RSA (Rivest-Shamir-Adleman).
• The RSA algorithm is best known for secure data transmission.
• ECC (Elliptic Curve Cryptography).
• ECC offers quick, safe, and efficient data transmission.

Encryption In Practical Field:

• Generate a private key and CSR
• Obtain certificate
• Install it on the server
• Configure the server for SSL and TLS usage
• Client Side Consideration
• Make sure the client has support and the latest system
• A trusted certificate authority is essential
• Upgradation
• Keep your browsers  updated
• Look for the latest root certificates

Digital Certificates and PKI

Digital certificates are important for the identities of entities involved in communication. Public Key Infrastructure (PKI) is the framework that manages digital certificates and the public key encryption process.

Components of PKI:

• Trust Chain: It is a series of certificates from a trusted root CA to the end-entity certificate.
• Certificate Authority (CA): It issues digital certificates.
• Registration Authority (RA): It verifies the identity of entities
• Certificates: It contains the public key and details about the certificate holder.

What is SSL (Secure Sockets Layer)?

Secure Sockets Layer, or SSL, is a cryptographic protocol designed to secure communication over a computer network. SSL operates by encrypting the data exchanged between the client and server, preventing unauthorized access and ensuring the confidentiality and integrity of the information. SSL uses a combination of symmetric and asymmetric encryption algorithms to establish a secure connection.

During the SSL handshake, the client and server negotiate the encryption algorithms and exchange cryptographic keys, facilitating secure communication. Over time, vulnerabilities were discovered in earlier versions of SSL (SSL 1.0, 2.0, and 3.0), leading to subsequent improvements and the development of its successor, TLS.

What is TLS (Transport Layer Security)?

TLS operates like SSL, using encryption algorithms and a handshake process to secure data transmission. Like SSL, TLS employs symmetric and asymmetric encryption for data confidentiality and integrity. The TLS handshake involves the exchange of cryptographic parameters, authentication of the server and, optionally, the client, and the establishment of a secure session key.

TLS has undergone several versions, with TLS 1.0, 1.1, 1.2, and 1.3 being the major iterations. TLS 1.3, the latest version, introduces improvements in security, performance, and the removal of outdated features.

Revocation and Record Protocol

• Revocation: Whenever certificates get compromised or expired they have to be revoked. This mechanism involves CRLs ( Certificate Revocation Lists) and OCSP (Online Certificate Status Protocol).
• Record Protocol: The SSL vs TLS record protocols serve the purpose of encapsulation of application data into the secured data. It uses MAC (Message Authentication Code) to ensure integrity.

Certificate Authority

It issues and also manages the digital certificates as mentioned earlier. Now let us get into its detailed overview. 

Root Certificate: It is expressly trusted and stored in the client’s trust score. It is just like an anchor of the trust chain and is signed by the certificate authority. 

Trust Chain: As the name implies it ensures the establishment of trust. Because its intermediate certificates link the end-entity certificate to the root certificate. 

Issuance of Certificates: The certificate authority issues the certificates. It involves the process of verification of the applicant’s identity through various validation methods (which will be discussed next in the article). This certificate has various essentials like public key, subject information, and the certificate authority’s digital signature.

Revocation of Certificates: As mentioned earlier when a certificate is no needed longer or gets compromised, it has to be revoked. Certificate authority uses CRLs ( Certificate Revocation Lists) and OCSP (Online Certificate Status Protocol) to maintain the record or to check if there is any revocable certificate present. 

Configuration and implementation

Here is the detailed process of configuration and implementation:

Server-side setup and configuration:

Configuration on the server side of SSL vs TLS is important for secure communication. It comprises the following:

• CSR (Certificate Signing Request) and Production of private key
• Obtaining a certificate from the Certificate authority and its installation
• Configuration of the server so that it can use SSL vs TLS

Client-side considerations:

For effective functioning, clients must have the latest and updated browsers and applications that support TLS and SSL protocols and can recognize the trusted certificate authority. 

Apache and Nginx Configuration

Apache Configuration: You have to enable SSL vs TLS modules and have to specify protocols and cipher suites. For the configuration of SSL vs TLS on Apache, you have to update the https.conf or ssl.conf files with the paths to the private key, certificate authority, and certificates. Open your file and add this code line:

• SSLProtocol -all +TLSv1.2 +TLSv1.3

Then restart the Apache.

Nginx Configuration: You have to update Nginx.conf for Nginx configuration. As for Apache, you also have to update this file with the paths to the private key, certificate authority, and certificates. Open the Nginx configuration file and add this code:

• ssl_protocols TLSv1.2 TLSv1.3;

Then restart Nginx.

IIS and Windows server configuration

You have to use IIS Manager to import SSL and TLS certificates and bind it to appropriate websites

Server Configuration and Optimization

TLS protocol versions and ciphers

Transport Layer Security is next in line to the Secure Sockets Layer. Both provide certain levels of authority. There are some different TLS protocol versions:

• TLS 1.0: It was introduced in 1990 but had some lackings.
• TLS 1.1: It is the second version introduced in 2006 aiming at fixing the former’s lackings.
• TLS 1.2: It was again aimed at the fixation of the lackings of TLS 1.2 possessing enhanced security functions launched in 2008.
• TLS 1.3: It is the newest and latest as introduced in 2018. It simplifies the handshake process and has enhanced cryptographic algorithms.

Cipher Suites

These are crucial for determining the algorithms used for encryption, message authentication, and key exchange. To secure a server, you have to choose the right cipher suits.

SSL and TLS compression and Caching

SSL and TLS compression were introduced to improve performance. However, it came out to be incompatible as it paved the path of compromising encrypted data. It is crucial to mitigate the problem by disabling the compression. Here is the process for Apache and Nginx:

For Apache:

1. Open the Apache configuration file.
2. Add this “SSLCompression off”
3. Restart Apache

For Nginx:

1. Open the Nginx configuration file
2. Add this ssl_compression off;
3. Restart Nginx

SSL and TLS Caching:

It improves performance by storing session data by preventing repeating the full handshake process. 

Configuration of SSL and TLS Caching:

For Apache:

1. Open the Apache Configuration file
2. Add this code line “SSLSessionCache shmcb:/var/run/ssl_scache(512000)

SSLSessionCacheTimeout 300”

3. Restart Apache

For Nginx:

1. Open the Nginx configuration file
2. Add this code line “ssl_session_cache shared:SSL:10m;
