256-Bit SSL
Today 256-Bit SSL is the most secure encryption available for SSL connections. It delivers an extended layer of security for users’ data and sensitive information. Compared to 128-Bit SSL, 256-Bit SSL has a larger encryption key size, which makes it harder to crack. Users’ private data such as name, number, email address, location, sensitive passwords, and financial & social credentials can be secured with 256-bit SSL encryption.
Whether it is a DDoS Attack, brute-force attack, phishing attack, or any other attack, websites using 256-bit SSL encryption will be suitably protected. Leading web browsers, operating systems, and mobile OS support 256-bit SSL encryption, so your users will be safe no matter how they connect to your website.
128-bit SSL
The 128-bit informs users that the key that is used for encryption to secure the data that is transmitted between a browser and the web server is 128 bits (mathematically it would be 2 times 128). Since the size of 128 bits is enormous, it is computationally impossible to crack, and hence called secure SSL security.
Authentication
The process of determining that the message hasn't been altered since it left the point of its source. Authentication, secure authentication, or security SSL security for a person, is typically derived from something the user is aware of or is. Many SSL Authentication Systems Which Provide SSL Internet Security and Online Payment System Security Are Now Shifting Toward Public Key Encryption.
Authentication Header
The Internet IPsec protocol, A field that instantly follows the IP header of an IP datagram. It provides security and authentication of the message. Additionally, it protects against replay attacks. It also secures authenticating the datagram, similar to secure SSL digital ID verification.
Authentication Token
A portable device to authenticate users. Authentication tokens work using challenge/response or time-based codes or other methods. It could be paper-based lists of passwords that are one-time.
Authenticator
A record that contains information that can be viewed that was created with the session key, which is used only by the server and the client.
Authenticity
SSL Certificate security must be authentic and verifiable. When it comes to SSL Internet security and network security, it is crucial to ensure that the authenticity of SSL certificates isn't taken for granted.
Authenticode
Technology that allows one to determine who has published an application and also to confirm that it was not altered. It also proves it is the original digital certificate that is used to sign that code came from the authority responsible for the certificate in the first place.
Authorization
The grant of access as well as other permissions to an individual or process that is authorized.
Certificate
A document that proves the authenticity of an organization as well as a web-based browser. It is used to prove that the data exchanged on networks is coming from the source intended. The certificate is signed digitally either by a Certificate Authority or is self-signed. It includes CA certificates, CA certificates, client CA certificates, certificates for clients, and server certificates.
Certificate Revocation List
A list kept by the Certificate Authority of all certificates which have been canceled, however, they are not expired. A certificate can be removed because the private key of the user is thought to be compromised and the user has been no longer accredited by this Certificate Authority, or the Certificate Authorities private key is believed as compromised.
Certification
A comprehensive evaluation of both the technical and nontechnical security features of a system, as well as other security measures that are used to facilitate the accreditation process which determines the extent to which a strategy and its implementation meet certain security standards.
Certification Authority (CA)
A third-party organization can be used to verify the authenticity of a party to the transaction via HTTPS and its public key. Certification authorities can be recognized and trusted organizations for transactions on the internet however, if HTTPS is being used by companies on their internal networks an internal department within the organization could play this function.
CPS (Certification Practice Statement)
CPS stands in the sense of Certification Practice Statement. It is the CPS is a publication by the Certification Authority and outlines the policies and procedures employed by the company in issuance and managing digital certificates.
CRL (Certificate Revocation List)
CRL is a short form for CRL that stands for Certificate Revocation List. It is a digitally signed data file that includes the information of every digital certificate that has been canceled. The CRL is able to be downloaded and installed in the user's browser. It also ensures that the browser does not accept a revoked digital certificate.
CSR (Certificate Signing Request)
CSR is a short form to mean Certificate Signing Requirement. When applying for an SSL certificate, the first step is to set up CSRs on your website server. This is where you tell your web server a few details regarding your site and business; it then generates a CSR file. This file is needed when you apply for an SSL certificate. Instructions on how to make CSRs CSR with the most well-known web server applications are available here.
Digital Signature
Digital signatures (not to be confused with digital certificates) refers to an electronic, rather than a signature written. It can be used to sign any type of communication, regardless of whether it's secured or not but only to ensure that the recipient can be certain of the identity of the sender and that the message has arrived in good condition. Digital certificates contain a digital signature that is signed by the certificate's issuing authority to allow anyone to confirm that the certificate is authentic. The other advantage of a digital signature is that it can be easily transferred and is not easily defused or imitated by anyone else and is also time-stamped.
Digital Signature Algorithm (DSA)
An algorithm to create digital signatures, created through NIST along with the NSA. To sign a message Jean employs her DSA Sign Algorithm to encode the digest of the message by using the private keys of her. In all practical terms, it is impossible to decrypt this data. Anyone who receives the message along with its digital signature can confirm that the signature is valid by applying the DSA Verify Algorithm to analyse the following data including the signature that was received as well as an analysis of the received message and Jean's private key. If the result of this algorithm is in line with some part that is a digital signature, then the digital signature has been verified and it is clear that the content is not changed. Contrary to RSA and other signatures based on encryption methods, DSA has no ability to decrypt or encrypt data.
Digital Signature Standard (DSS)
A National Institute of Standards and Technology (NIST) standard for digital signatures is used to authenticate both the message as well as the signer. DSS has a security level comparable to RSA (Rivest-Shamir-Adleman) cryptography, having 1,024-bit keys.
E-Commerce
Simply put, it is the act of selling products over the internet. It could be either business to Business (B2B) or Business to Consumer (B2C).
Encryption
Encryption is the act of altering data to a format that can only be read by the intended recipient. To decipher the message the recipient of the encrypted data should have the appropriate decryption key. In the traditional encryption scheme, both the sender and receiver share the same encryption key to both encrypt or decrypt information. The encryption methods that use public keys employ two keys that are a public key that is accessible to anyone in conjunction with a private key that is only owned by the one who made the key. This way it is possible for anyone to send an encrypted message using the owner's public key however, only the owner owns the private key required to decrypt the message.
Firewall
A secure system for monitoring and analysing traffic using an internal secure and trusted server network, and the external secured server network which is not dependable similar to the Internet. Firewalls can be utilized to detect, stop, or reduce certain kinds of attacks on secure servers. This is a way to provide Internet security as well as online security.
Host headers SSL
Host headers can be used by IIS to assist in providing multiple websites via an IP address. Because an SSL certifies a specific IP address, host headers are not able to be utilized with SSL. If the SSL protocol is activated, the host header data is encrypted. As a result, the server doesn't know which website it should connect to. This is the reason why a dedicated IP address for each website has to be utilized.
Browsers are able to communicate with a web server using HTTP and also over HTTPS. Connecting using HTTPS requires typing HTTP:// prior to any domain's URL, or domain's name provided that the server is secured with an SSL certificate and that the connection is secure and encrypted.
IIS (Internet Information Services)
IIS is an abbreviation to mean Internet Information Services and is Microsoft's most popular web server software.
Password
A private/secure character string that is used to authenticate an identity that provides secure authentication and safe SSL authentication, usually with digital signatures or digital certificates such as a 128-bit SSL digital certificate. Passwords are needed for users' authentication security online or for the security of authorization. They are a part of a secure email using SSL certificates, as well as all other terms associated with online security.
Protocol
The same as "protocol" in human communication which is an agreed-upon set of guidelines to communicate in diplomatic contexts. On the Internet, protocols are an accepted method of communicating as well as receiving messages.
Private Key
The user's key is able kept secret when using Asymmetric encryption. It is able to decrypt and encrypt data in a single transaction, but it cannot do both.
Public Key
The password that an individual will let the world learn about Asymmetric encryption. It can decrypt or encrypt data in a single transaction, but it cannot do both.
Root Certificate
Self-signed certificate issued by the root level Certificate Authority (CA).
Secure Server
A website that employs security protocols such as SSL to decrypt and encrypt messages, data, and online payment gateways that accept credit cards to secure them from fraud, false identification, or third-party hacking. When you purchase from a secure Web server guarantees that a person's credit card or personal details are protected by an encrypted code that is impossible to crack. The most popular security protocols are SSL, SHTTP, SSH2, SFTP, PCT, and IPsec.
SSL (Secure Sockets Layer)
SSL is an abbreviation in the form Secure Sockets Layer. SSL is a short form for Secure Sockets Layer. SSL protocol was created in the company Netscape which is supported by all the popular web browsers like Internet Explorer, Netscape, AOL, and Opera. To enable SSL to work, an SSL-certifiable certificate from a Certification Authority must be installed on the server hosting the website. SSL can be then used to protect the information transmitted (secure SSL transactions) between the web server and the browser (and reverse). The browsers signal an SSL secure session by changing the HTTP code to HTTPS and then displaying a tiny padlock. Web users can click the padlock in order to see the SSL certificate.
SSL Key
An SSL Key, also known as a Private Key, is the secret key that is associated with your SSL certificate. It is stored in a secure location on your web server. When you create CSR, CSR your server will also generate an SSL Key. After you have received your SSL certificate is issued, you'll need for you to download the SSL certificate onto your website server, which effectively binds the SSL certificate with its SSL key. Because SSL keys are only used by the web server, the SSL certificate is the only one utilized by the web server, it's a method of proving that the server is able to legitimately utilize this SSL certificate.
If you do not possess or lose both of the SSL keys as well as the SSL certificate, then you will not be able to utilize SSL on your website server.
SSL handshake
The SSL handshake refers to the term used to describe the process that involves the web server and browser in establishing an SSL session. It is the SSL handshake is the process of the web browser accepting the SSL certificate and sending "challenge" data to the webserver to prove cryptographically that the server is holding the SSL key that is associated with the SSL certificate. If the cryptographic test succeeds, then the SSL handshake is completed, and the server will be in an SSL session in conjunction with the browser. In an SSL session, the data that is transmitted between the web server and the web browser will be secured. The SSL handshake only takes one second to be completed.
SSL Port / HTTPS Port
The port represents a "logical connection place" where the browser can connect to the web server. The SSL port, also known as the "HTTPS" port HTTPS port will be the one that you assign to your server to allow SSL traffic. The standard port that industry professionals use is port 443 as many firewalls and networks require port number 443 to be utilized to support SSL. However, it is possible to identify additional SSL ports or HTTPS ports that can be used when needed. The most common port used to handle non-secure HTTP web traffic is 80.
SSL Proxy
SSL Proxy allows non-SSL-aware applications to be protected by SSL. It is SSL Proxy that will add SSL support by plugging into connections between the web client (or the client) as well as the server.
SSL Accelerator
Typically, the SSL handshake and the subsequent encryption of information between a browser and a web server are performed by the server. However, for certain highly popular websites, the volume of traffic served via SSL implies that the server becomes overwhelmed or is simply unable to handle the amount of SSL connections. In these cases, an SSL Accelerator could help increase the number of concurrent connections as well as the speeds of SSL handshake. SSL Accelerators provide the same services for SSL as web servers.
Shared SSL & Wildcard SSL
The possibility exists for website hosting providers to share one SSL certificate. This permits the identical SSL certificate to be utilized on a number of websites, without having to issue separate SSL certificates for each hosting customer. The most efficient method of sharing SSL is using the Wildcard SSL certificate. This permits the unlimited possibility of using multiple subdomains with the same domain. The Wildcard SSL certificate allows the web hosting company to give each customer a secure sub domain, such as customer1.webhost.com, customer2.webhost.com, etc. This is also possible for companies that want to protect multiple subdomains within their enterprise network.
TLS (Transport Layout Security)
TLS is a shorthand to mean Transport Layer Security. The TLS protocol was designed to eventually replace SSL. SSL protocol, but at moment, only a few companies use it in place of SSL.
Verification
The method compares two levels of the explication system to ensure that the system is in proper correspondence.
