Free Network-and-Security-Foundation Questions Attempt

Accounting(also known asauditing or logging) is a network security concept that tracks user activities, includingsuccessful and failed authentication attempts, system changes, and resource access. This helps in detecting and mitigating security breaches.

Authenticationverifies user identity but does not track activity.

Availabilityensures systems remain operational.

Authorizationcontrols user permissions but does not log activities.

Restricting physical accessto data storage facilities is a critical part of database security. Even with strong cybersecurity measures,unauthorized physical accessto servers can lead to breaches. Security strategies includebiometric authentication, surveillance cameras, and restricted entry zones.

Disclosing breachesis required by compliance laws but does not protect data proactively.

Developing algorithmsimproves security but is not a fundamental checklist item.

Outsourcing data managementcan introduce security risks if not properly controlled.

Data modification attacksinvolve unauthorized changes to stored data, altering information to mislead, disrupt, or destroy integrity. Attackers may modify logs, transactions, or records for fraud or sabotage.

Launch pointis when a system is used to attack others.

Data exportis the theft of data.

Denial of availabilitymakes data inaccessible, but does not necessarily modify it.

Infrastructure as a Service (IaaS)provides virtualized computing resources over the cloud, including virtual machines where users can install and configure their own operating systems and applications. It offers flexibility and scalability without requiring hardware investment. Examples include AWS EC2 and Microsoft Azure Virtual Machines.

FaaSexecutes small code functions without infrastructure management.

PaaSprovides a managed platform but not full OS control.

SaaSoffers ready-to-use applications without infrastructure control.
