  • What is security automation? - Security automation uses technology to remove high-volume manual processes from security operations to detect cyberthreats, which saves time by integrating different workflows into repeatable processes.
  • What is security by design? - Security by design is an approach to software and hardware development that seeks to make systems as free of vulnerabilities and impervious to attack as possible through such measures as continuous testing, authentication safeguards and adherence to best programming practices.
  • What is security information and event management (SIEM)? - Security information and event management (SIEM) is an approach to security management that combines security information management (SIM) and security event management (SEM) functions into one security management system.
  • What is shared responsibility model? - A shared responsibility model is a cloud security framework that dictates the security obligations of a cloud computing provider and its users to ensure accountability.
  • What is SSH (Secure Shell) and How Does It Work? - SSH (Secure Shell or Secure Socket Shell) is a network protocol that gives users -- particularly systems administrators -- a secure way to access a computer over an unsecured network.
  • What is static application security testing (SAST)? - Static application security testing (SAST) is the process of analyzing and testing application source code for security vulnerabilities.
  • What is the CIA triad (confidentiality, integrity and availability)? - The CIA triad refers to confidentiality, integrity and availability, describing a model designed to guide policies for information security within an organization.
  • What is the Cybersecurity Information Sharing Act (CISA)? - The Cybersecurity Information Sharing Act (CISA) allows United States government agencies and non-government entities to share information with each other as they investigate cyberattacks.

  • What is the Mitre ATT&CK framework? - The Mitre ATT&CK -- pronounced miter attack -- framework is a free, globally accessible knowledge base that describes the latest behaviors and tactics of cyberadversaries to help organizations strengthen their cybersecurity strategies.
  • What is the Nessus vulnerability scanning platform? - Nessus is a platform developed by Tenable that scans for security vulnerabilities in devices, applications, operating systems, cloud services and other network resources.
  • What is the RSA algorithm? - The RSA algorithm (Rivest-Shamir-Adleman) is a public key cryptosystem that uses a pair of keys for securing digital communication and transactions over insecure networks, such as the internet.
  • What is the Twofish encryption algorithm? - Twofish is a symmetric-key block cipher with a block size of 128 bits and variable-length key of size 128, 192 or 256 bits.
  • What is the zero-trust security model? - The zero-trust security model is a cybersecurity approach that denies access to an enterprise's digital resources by default and grants authenticated users and devices tailored, siloed access to only the applications, data, services and systems they need to do their jobs.
  • What is threat intelligence? - Threat intelligence, also known as cyberthreat intelligence, is information gathered from a range of sources about current or potential attacks against an organization.
  • What is Transport Layer Security (TLS)? - Transport Layer Security (TLS) is an Internet Engineering Task Force (IETF) standard protocol that provides authentication, privacy and data integrity between two communicating computer applications.
  • What is two-factor authentication (2FA)? - Two-factor authentication (2FA), sometimes referred to as two-step verification or dual-factor authentication, is a security process in which users provide two different authentication factors to verify themselves.
  • What is unified endpoint management (UEM)? A complete guide - Unified endpoint management (UEM) is an approach to securing and controlling desktop computers, laptops, smartphones and tablets in a connected, cohesive manner from a single console.
  • What is unified threat management (UTM)? - Unified threat management (UTM) is an information security system that provides a single point of protection against cyberthreats, including viruses, worms, spyware and other malware, as well as network attacks.
