  • Indicators of Attack

    Indicators of Attack (IoA) Indicators of Attack (IoAs) are behavioral signs that suggest an attack is either in progress or being attempted. Unlike Indicators of Compromise (IoCs), which provide evidence after a breach has occurred, IoAs concentrate on detecting suspicious behaviors, tactics, and techniques used by attackers in real-time. IoAs assist security teams in identifying…

  • Indicators of Compromise

    Indicators of Compromise (IoC) Indicators of Compromise (IoCs) are pieces of forensic evidence or observable data that suggest a system, network, or account has been compromised by malicious activity. IoCs are typically discovered during or after a cybersecurity incident and are used by security teams to identify, investigate, and contain attacks.  IoCs are considered reactive…

  • Diffie Hellman

    Diffie Hellman  A cryptographic method that allows two parties to securely establish a shared secret key over an insecure communication channel, such as the internet, without ever directly transmitting the key itself. This shared secret can then be used to encrypt subsequent communications using symmetric encryption algorithms.Developed by Whitfield Diffie and Martin Hellman in 1976,…

  • Rivest Shamir Adleman

    Rivest Shamir Adleman (RSA) A public-key cryptosystem that uses a pair of mathematically related keys: a public key for encryption and a private key for decryption. It was developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman and remains one of the most widely used asymmetric encryption algorithms in the world.RSA relies on…

  • Advanced Encryption Standard

    Advanced Encryption Standard (AES) A symmetric block cipher selected by the U.S. National Institute of Standards and Technology (NIST) in 2001 to replace the older Data Encryption Standard (DES). AES is widely used to protect sensitive and classified information in both government and commercial applications.AES encrypts data in fixed-size blocks of 128 bits and supports…

  • Rivest Cipher 4

    Rivest Cipher 4 (RC4) A stream cipher designed by Ronald Rivest in 1987. Unlike block ciphers, which encrypt fixed-size blocks of data, RC4 encrypts data one byte at a time. This makes it well-suited for applications where data arrives in variable-length streams, such as network communications.RC4 generates a pseudorandom key stream based on an initial…

  • Data Encryption Standard

    Data Encryption Standard (DES)  A symmetric key block cipher that was widely used for securing electronic data. DES operates by encrypting 64-bit blocks of data using a 56-bit key, producing a corresponding 64-bit ciphertext block.DES follows the Feistel structure, which means it divides the data block into two halves and applies multiple rounds of substitution…

  • Identification, Authentication, Authorization, and Accountability

    Identification Identification is the process of claiming or declaring an identity, where a person, system, or object presents information that indicates who or what they are. It is the first step in identity verification, often involving credentials such as a username, ID number, card, or biometric data that represent the claimed identity. Identification by itself…

  • Access Controls

    Access Controls Access Control is a security technique that regulates who or what can view, use, or interact with resources in a system, thereby protecting it against unauthorized access. It involves defining and enforcing policies that determine permissions based on user roles, attributes, or contexts, ensuring that only authorized entities can perform specific actions. Common…

  • CIA Triad

    CIA Triad The CIA Triad is a fundamental cybersecurity model that encompasses three key principles for protecting information systems and data: Confidentiality, Integrity, and Availability. This model provides a straightforward framework for designing security controls and assessing risks, ensuring that information remains protected, accurate, and accessible when needed. These principles guide organizations in securing their…
