Security Basics Flashcards
What is the principle of least privilege?
The principle of least privilege means granting users and applications the minimum level of access or permissions needed to perform their tasks, reducing potential security risks.
What is multi-factor authentication (MFA)?
MFA requires users to provide two or more forms of authentication (e.g., a password and a fingerprint or SMS code) to access a system, enhancing security.
What is the difference between symmetric and asymmetric encryption?
Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a pair of public and private keys, where the public key encrypts and the private key decrypts.
What is a Trojan horse in terms of cybersecurity?
A Trojan horse is a type of malware that disguises itself as legitimate software, tricking users into installing it, allowing attackers to gain unauthorized access.
What is two-factor authentication (2FA)?
2FA is a security process in which the user provides two different authentication factors to verify themselves: something they know (a password) and something they have (a phone or hardware token).
What are the primary goals of cybersecurity?
The primary goals of cybersecurity are confidentiality (protecting data), integrity (ensuring data accuracy), and availability (ensuring access to data and resources).
What is a DDoS (Distributed Denial of Service) attack?
A DDoS attack involves overwhelming a server or network with traffic from multiple sources to make it unavailable to legitimate users.
