Authentication Methods Quiz

Authentication Methods: Directory Services, Federation, Attestation, SMS, Push Notification, Authentication Apps, TOTP, HOTP, Phone Call, Static Codes, Smart Cards, Biometric Factors

• Directory services keep all usernames and passwords in a single database, allowing for a large distributed database that is constantly replicated.
• Federation provides network access to partners, suppliers, customers, etc. with SSO and allows third parties to establish a trust relationship.
• Attestation proves the hardware is really yours, with remote attestation providing an operational report to a verification server.
• SMS can be used as a login factor but has security issues such as phone number reassignment and message interception.
• Push notification is similar to SMS but with a specialized app, still more secure than SMS but can have vulnerabilities.
• Authentication apps use pseudo-random token generators for convenience, with software-based token generators available on phones.
• TOTP is a common OTP method used by Google, Facebook, Microsoft, etc. with a time-based one-time password algorithm and a secret key configured ahead of time.
• HOTP is a one-time password method using HMAC-based one-time password algorithm and can use hardware or software tokens.
• Phone calls can provide the token but have similar disadvantages to SMS.
• Static codes are authentication factors that don't change, such as personal identification numbers or passwords.
• Smart cards are integrated circuit cards commonly used for credit cards and access control, requiring a physical card and using a digital certificate with multiple factors.
• Biometric factors include fingerprint, retinal, iris, voice, facial recognition, gait analysis, and vascular scanners, with different acceptance rates such as false acceptance rate, false rejection rate, and crossover error rate.
