ExisorWhat are Encryption Algorithms? Encryption is a means of transmitting messages or files in such a way that they are unreadable to anyone but the authorized recipient. Encryption uses complex algorithms to scramble data and decrypt the same data using a key provided by the message sender. Encryption ensures that information stays private and confidential, […]
What is Full Disk Encryption? Full disk encryption (FDE) or whole disk encryption is a means of protecting information by encrypting all of the data on a disk, including temporary files, programs, and system files. Some full disk encryption systems leave the boot sector of the disk unencrypted, while others encrypt that as well. Following […]
What is XML Encryption? Extensible Markup Language (XML) lets you define and store data in a shareable manner. XML supports information exchange between computer systems such as websites, databases, and third-party applications. Predefined rules make it easy to transmit data as XML files over any network because the recipient can use those rules to read […]
What is Packet Sniffing? When data has to be transmitted over the computer network, it is broken down into smaller units at the called data packets and reassembled on the receiver’s end in its original format. This data packet (aka- block, segment, datagram, cell) is the smallest unit of communication over a computer network. The […]
What are Cipher Suites? Cipher suites are sets of instructions that enable secure network connections through Transport Layer Security (TLS), often still referred to as Secure Sockets Layer (SSL). These cipher suites provide a set of algorithms and protocols that are required to secure communications between clients and servers. To initiate an HTTPS connection, the […]
What is Pretty Good Privacy Encryption? Pretty Good Privacy (PGP) is a security program used to decrypt and encrypt email and authenticate email messages through digital signatures and file encryption. PGP was one of the first public-key cryptography software applications that was publicly available, for free. Originally, it was used to enable individual users to […]
What are File-Sharing Best Practices? File sharing is a common, yet dangerous, daily business activity. Take time to evaluate your file sharing methods to ensure that you are choosing the most secure procedures. Consider the following best practices as you decide how you will send and receive files securely: Multi-factor authentication. Use multi-factor authentication (MFA) […]
What are Randomness and Entropy? Most modern encryption relies on randomly generated keys. Random numbers are used in many places within the realm of information technology, and they are also used in other fields, such as in the sciences. In mathematical statistics, randomness has been defined as, “of or relating to a type of circumstance […]
What is Elliptic Curve Cryptography? Elliptic Curve Cryptography (ECC) is a public-key algorithm based on the elliptic curve defined over a finite field. ECC works by creating a public key and a private key on an elliptic curve. The public key is shared with others, while the private key is kept secret. Encryption and decryption […]
What is Non-Repudiation? Non-repudiation means that a user cannot deny (repudiate) having performed a transaction. Non-repudiation is a regulatory notion commonly used in cybersecurity which refers to the service that confirms the origin and integrity of data. This assures that no party can deny sending or receiving a communication using encryption and digital signatures. It […]
