  • Quiz: Demystifying data encryption

    A five-question multiple-choice quiz to test your understanding of the data encryption content presented by expert Tom Bowers in this lesson of SearchSecurity.com's Data Protection Security School.  Quiz

  • Locking down database applications

    In this lesson, learn how to secure database apps by building roles and privileges and monitoring access to prevent insider abuse, plus satisfy regulators by properly segregating duties and limiting application access to sensitive database data.  partOfGuideSeries

  • Data encryption demystified

    Five years ago, security professionals needed a deep understanding of cryptography to make encryption work. Today, thanks to advancements in "practical" cryptography, data encryption is more user-friendly, and easier to implement and manage across mu...  partOfGuideSeries

  • Quiz: Storage security

    Regulations like SOX and the recently approved Personal Data Privacy and Security Act are bringing the importance of data protection to light. Loss of data – be it inadvertent or surreptitious -- can result in fines, loss of revenue and loss of...  Security Quiz

  • PING with Karen Worstell

    The Microsoft CISO discusses how she keeps Redmond and its products secure.  Information Security maga

  • Life at the edge part 3: Resistance to failure

    Learn how architecture, protocol and application-level protections work together to safeguard a Web infrastructure.  Security School

  • homomorphic encryption

    Homomorphic encryption is the conversion of data into ciphertext that can be analyzed and worked with as if it were still in its original form.  Homomorphic encryptions allow complex mathematical operations to be performed on encrypted data without c...  Definition

  • Advanced Encryption Standard (AES)

    The Advanced Encryption Standard (AES) is an encryption algorithm for securing sensitive but unclassified material by U.S. Government agencies and, as a likely consequence, may eventually become the de facto encryption standard for commercial transac...  Definition

  • Twofish

    Twofish is an encryption algorithm based on an earlier algorithm, Blowfish, and was a finalist for a NIST Advanced Encryption Standard (AES) algorithm to replace the DES algorithm.  Definition

  • network encryption (network layer or network level encryption)

    Network encryption (sometimes called network layer, or network level encryption) is a network security process that applies crypto services at the network transfer layer - above the data link level, but below the application level.  Definition

  • Escrowed Encryption Standard (EES)

    The Escrowed Encryption Standard (EES) is a standard for encrypted communications that was approved by the U.S. Department of Commerce in 1994 and is better known by the name of an implementation called the Clipper chip.  Definition

  • Encrypting File System (EFS)

    The Encrypting File System (EFS) is a feature of the Windows 2000 operating system that lets any file or folder be stored in encrypted form and decrypted only by an individual user and an authorized recovery agent.  Definition

  • data key

    In cryptography, a data key is a key (a variable value that is applied to a string or block of text to encrypt or decrypt it) that is used to encrypt or decrypt data only and is not used to encrypt or decrypt other keys, as some encryption formulas c...  Definition

  • Rijndael

    Rijndael (pronounced rain-dahl) is the algorithm that has been selected by the U.S. National Institute of Standards and Technology (NIST) as the candidate for the Advanced Encryption Standard (AES).  Definition

  • Data Encryption Standard (DES)

    Data Encryption Standard (DES) is a widely-used method of data encryption using a private (secret) key that was judged so difficult to break by the U.S. government that it was restricted for exportation to other countries.  Definition

  • encryption

    Encryption is the conversion of data into a form, called a ciphertext, that cannot be easily understood by unauthorized people. Decryption is the process of converting encrypted data back into its original form, so it can be understood.  Definition
