Key Terms to Review (18)
Access Control Lists: Access Control Lists (ACLs) are a set of rules that determine what access rights users or systems have to a particular resource, such as files, directories, or network devices. They are crucial for managing user permissions and help ensure that only authorized individuals can access sensitive information or perform specific actions. ACLs can be configured to allow or deny access based on various criteria, making them a vital part of identity and access management strategies.
Access reviewer: An access reviewer is a designated individual or system responsible for examining and validating access permissions within an organization. This role ensures that only authorized users have access to sensitive information and resources, playing a crucial part in maintaining security and compliance with policies and regulations.
Attribute-Based Access Control: Attribute-Based Access Control (ABAC) is a security model that grants or restricts access to resources based on user attributes, resource attributes, and environmental conditions. This approach allows for fine-grained access control, enabling organizations to enforce policies that take into account various factors such as user role, location, time of access, and other contextual information. ABAC is particularly valuable in complex environments where traditional access control models may fall short.
Biometric authentication: Biometric authentication is a security process that uses unique biological characteristics of individuals, such as fingerprints, facial recognition, or iris scans, to verify identity. This method offers enhanced security by ensuring that access is granted only to individuals whose biometric data matches stored templates. It plays a crucial role in protecting sensitive information and enabling secure access across various platforms, making it increasingly relevant in identity verification and public safety.
Credential stuffing: Credential stuffing is a cyber attack method where attackers use stolen usernames and passwords from one data breach to gain unauthorized access to accounts on different platforms. This tactic exploits the common habit of users reusing credentials across multiple sites, making it easier for attackers to compromise multiple accounts once they have access to a set of valid login details. The success of credential stuffing attacks heavily relies on the automated use of bots to rapidly test these credentials across various services.
Data privacy: Data privacy refers to the proper handling, processing, storage, and usage of personal information, ensuring that individuals have control over their data and that it is protected from unauthorized access and misuse. It encompasses various practices and regulations designed to safeguard sensitive information in an increasingly digital world, impacting how organizations collect, share, and utilize data.
Digital identity: Digital identity refers to the online representation of an individual, organization, or entity, encompassing all the data and attributes associated with them in the digital realm. It includes personal information such as usernames, email addresses, social media profiles, and other digital footprints that can reveal a person's preferences, behaviors, and affiliations. Digital identity plays a crucial role in how users access online services and interact with various platforms, making it essential for identity and access management strategies.
GDPR: The General Data Protection Regulation (GDPR) is a comprehensive data protection law in the European Union that aims to enhance individuals' control over their personal data and unify data privacy laws across Europe. It establishes strict guidelines for the collection, storage, and processing of personal data, ensuring that organizations are accountable for protecting users' privacy and fostering a culture of informed consent and transparency.
HIPAA: The Health Insurance Portability and Accountability Act (HIPAA) is a federal law that establishes standards to protect sensitive patient health information from being disclosed without the patient's consent or knowledge. It ensures the privacy and security of health data while also setting regulations for data retention, encryption, and breach notification, which are crucial in today's digital health landscape.
Identity administrator: An identity administrator is a professional responsible for managing and overseeing the identity and access management systems within an organization. They ensure that users have appropriate access to systems and data while maintaining security protocols, managing user accounts, permissions, and roles. This role is crucial for protecting sensitive information and ensuring compliance with regulations related to data privacy and security.
Identity Federation: Identity federation is a system that allows multiple organizations to share identity information and user authentication, enabling users to access resources across different domains with a single set of credentials. This approach simplifies user management and enhances security by reducing the need for multiple logins while ensuring that identity verification is maintained across participating entities. It promotes seamless collaboration between organizations and supports various services such as Single Sign-On (SSO).
Identity theft: Identity theft is the act of obtaining and using someone else's personal information, such as social security numbers, credit card details, or other sensitive data, without their permission, typically for financial gain. This malicious act not only impacts the victim financially but can also result in long-term damage to their credit and personal reputation, highlighting important concerns around digital rights, privacy, and data security.
Informed Consent: Informed consent is the process by which individuals are fully informed about the data collection, use, and potential risks involved before agreeing to share their personal information. This principle is essential in ensuring ethical practices, promoting transparency, and empowering users with control over their data.
Least Privilege Principle: The least privilege principle is a security concept that advocates for giving users and systems the minimum level of access necessary to perform their tasks. This principle is crucial in minimizing potential security risks by limiting the exposure of sensitive information and system functionalities. By adhering to this principle, organizations can effectively reduce the attack surface and enhance overall security posture.
Multi-factor authentication: Multi-factor authentication (MFA) is a security process that requires users to provide two or more verification factors to gain access to a resource, such as an application, online account, or database. This method significantly enhances security by combining something the user knows (like a password) with something the user has (like a smartphone) or something the user is (like a fingerprint). By employing multiple verification methods, MFA helps protect sensitive information from unauthorized access and reduces the risk of identity theft.
Role-based access control: Role-based access control (RBAC) is a method of regulating access to computer or network resources based on the roles of individual users within an organization. This approach simplifies security management by assigning permissions to specific roles rather than to individual users, ensuring that employees only have access to the information necessary for their job functions. By doing so, RBAC enhances security, supports compliance requirements, and makes it easier to manage user permissions as roles can be modified as needed without changing individual user accounts.
Single Sign-On: Single sign-on (SSO) is an authentication process that allows a user to access multiple applications with one set of login credentials. This means users don’t have to remember different usernames and passwords for each application they use, enhancing user experience while reducing password fatigue. SSO works by establishing a trust relationship between an identity provider and service providers, streamlining identity management across various platforms.
User Provisioning: User provisioning refers to the process of creating, managing, and maintaining user accounts and access rights within an organization’s information systems. This process ensures that individuals have the necessary permissions to access resources relevant to their roles while also enforcing security protocols to prevent unauthorized access. Effective user provisioning involves not just the initial setup of user accounts but also ongoing management throughout a user’s lifecycle within the organization.
