Study Notes

Access Controls

Access control is the process of identifying and granting privileges to users for information, systems, or resources.
Three types of access control methods: logical, physical, and administrative.

Physical Access Controls

Physical access controls are used by airlines to screen checked luggage and carry-on baggage.
Presenting a ticket with an assigned seat and an acceptable form of identification is required.
Badges with employee ID, name, and picture are used to grant employee access to public and private organizations.
Keyboards and physical asset containers like file cabinets, safes, or vaults with codes, keys, or combinations control access to restricted rooms.
Biometric access control systems can handle thousands of users and be configured via a secure web connection.
Iris cameras are the most accurate biometric devices and can be used in various situations.

Logical/Technical Access Controls

Protecting electronic information involves both physical and logical access controls.
Logical access controls often entail multiple security controls and authentication techniques.
Access to critical data should be determined by a person's role, and the need for access should be reviewed regularly.
The Principle of Least Privilege (POLP) states that users should have only the bare minimum privileges necessary to perform their function.

User Authentication

Identification credentials must be issued to authenticate the user, and three factors can be required: knowledge, possession, and inheritance.
Assurance increases with a second and third authentication technique.
Multi-factor authentication (MFA) is the norm, requiring users to enter a password and additional information.

Access Controls and Cloud Computing

Access control is a key concern when moving critical applications and sensitive information to public and shared cloud environments.
Cloud providers must provide access controls at least as robust as those employed by the client firm.
Employees of the cloud service provider must be screened and trained to the same high standards.

Administrative action involves developing policies and procedures, providing education and training, and monitoring and evaluating use.
Access control processes should complement social media and records management policies.
Social media activities on behalf of the firm can be limited to authorized employees with specific roles and responsibilities.

Proof of Personhood Online

Digital verification using zero-knowledge proofs based on a unique iris code can verify a person's humanness and uniqueness online.
Worldcoin's biometric imaging device, the Orb, captures, records, and converts iris images into a string of numbers referred to as an iris code.
World ID 2.0 offers more powerful privacy features and the ability to integrate with popular e-commerce, gaming, and social media platforms.
