An Overview Of Secure Sockets Layer In Cybersecurity
By Tom Seest
Security experts rely on secure sockets layer (SSL) technology as the standard method for guaranteeing that any information exchanged between two systems remains private and secure. This helps stop criminals from intercepting sensitive data transmissions like credit card numbers and passwords, protecting all transmitted information as it travels between systems.
SSL is a cryptographic protocol that authenticates, encrypts, and decrypts network connections. It encrypts segments residing at the transport layer – that is, those parts of connections above the program layer – as well as provides other protection for sensitive information on these connections.

Security sockets layer (SSL) is a network protocol developed by Netscape in the 1990s that encrypts data and authenticates connections. Nowadays, SSL is commonly used to protect online shopping sites and other websites with sensitive personal data.
Encrypting network connection segments at the transport layer, which sits atop network connections above the program layer, protect them from prying eyes.
The primary function of technology is to protect sensitive information. For instance, when entering credit card details on a secure website, the data is encrypted and decrypted by the web browser before leaving your device. This ensures that only authorized personnel have access to this sensitive data.
SSL was once a go-to encryption protocol due to its security and scalability, but it also had its shortcomings. While SSL remains in use today, TLS has replaced it as the premier choice for online communication security. TLS utilizes standardized cryptographic keys that perform similar functions as more esoteric SSL but are simpler and easier to set up and maintain. Most commonly, TLS is employed when connecting HTTPS connections directly from your browser.

Secure Sockets Layer (SSL) is the industry standard technology used in cybersecurity to encrypt internet connections, protecting them from hackers and criminals reading any data transferred between two systems. It safeguards sensitive information like credit card numbers and passwords sent between websites or applications and their clients – like web browsers – or between networks of servers.
SSL uses encryption to protect data, ensuring anyone attempting to intercept it only sees a scrambled mix of characters that make deciphering it difficult. The encryption works on an asymmetric basis; each party needs both a public and private key in order to communicate with each other securely. The public key encrypts the data while the private key decrypts it.
This process creates a mathematical formula that cannot be decrypted with brute-force methods. The key pairs, linked by an intricate series of numbers, can only be decrypted using the original secret – known as the “master secret.
Asymmetric encryption comes in various forms and applications, making it a suitable solution for many purposes, such as protecting mobile communications and banking transactions.
The most widely used form of asymmetric encryption is RSA chain encryption. This fast, secure method of protection is hard to break using brute force, making it ideal for safeguarding sensitive information such as login credentials or bank account numbers.
Another form of asymmetric encryption is the point-based curve cipher. This faster solution requires less computing power than pure RSA chain encryption and has lower security levels.
It provides high resistance to brute force attacks and makes for secure email messages. Furthermore, it’s compatible with a wide range of networks and protocols, such as the Internet Protocol (IP).
SSL was once the go-to technology for securing internet traffic but has now been replaced by Transport Layer Security (TLS). TLS has gone through numerous iterations and is now widely used as the standard encryption standard on websites. While many still rely on SSL, it’s essential that they transition over to TLS as soon as possible in order to keep your site secure from malicious attackers who are constantly evolving their methods and protocols.

When visiting a secure website, look for the padlock icon in the address bar. That indicates it uses secure sockets layer (SSL) encryption to keep your data safe. SSL shields sensitive information from hackers and criminals so only authorized personnel can view and utilize it.
To accomplish this, the secure sockets layer first assesses the data to be sent and its relation to other systems. It then decides how best to encrypt that data with specific algorithms; ultimately, only the system with which it was originally sent can decrypt it.
Security through the secure sockets layer (SSL) is an integral element of internet connections, as it encrypts personal and secure information as it travels from one system to another. This helps shield personal and financial details, such as credit card numbers, from being viewed or used by unauthorized third parties.
Authentication is a process in which the server verifies that it has received permission from the client to transfer sensitive information between them. To do this, the server needs to apply a certificate that identifies the company or organization and proves its legitimacy. This level of authentication should be employed on public-facing websites collecting personal data from site users.
Once SSL authentication is complete, the secure sockets layer allows data transmission between clients and servers over an encrypted connection that cannot be intercepted by hackers or criminals.
Today, many different security technologies are in use; however, the secure sockets layer remains a cornerstone of cybersecurity and should be taken into account by every professional. Furthermore, although SSL has been around for some time now, it is slowly being replaced by Transport Layer Security (TLS).
SSL remains an integral tool in cybersecurity, but the rise of TLS must be taken into account as technology progresses. This shift will impact how secure communications will be in the future and require systems to be updated accordingly.

The SSL protocol is a security measure designed to guarantee privacy when communicating over the Internet. It protects confidential information like credit card numbers, IP addresses, and social security numbers by encrypting it before transmission across the network, making it difficult for hackers to intercept or read sensitive data.
Encryption is achieved using a combination of algorithms, including SHA (Secure Hash Algorithm), MD5, and MAC. These processes generate the Message Authentication Code (MAC), which is appended to data before transmission over the internet.
MACs are what differentiate a secured connection from an unencrypted one, as once data has been encrypted, it cannot be altered or decoded.
When a user is on a secure website, their browser will display a green padlock icon to signify it is protected by the SSL protocol. This industry-standard security measure helps guarantee the privacy and integrity of data exchanged between a web server and a user’s browser.
Before initiating a secure connection, the client must acknowledge that it recognizes and trusts the server that issued the certificate. Once acknowledged, they will share a public key with the client to establish an encrypted session involving both message encryption and server authentication.
Finally, the SSL protocol is just one of many cryptography protocols used to keep online data secure. They include Transport Layer Security (TLS) and the more well-known Secure Sockets Layer, invented by Netscape in 1995. While this latter version remains the most well-known, it has since been replaced by TLS 1.3, which now serves as the industry standard for website encryption.
