CompTIA Updated SY0-701 Exam Questions and Answers by tadhg

Hardening access to a new database system requires implementing controls that restrict and secure how administrators and applications connect to the database. A jump server (A) is a hardened intermediary system used to manage access to sensitive systems such as databases. By forcing administrators to authenticate through a controlled, monitored jump host instead of connecting directly, organizations reduce attack surfaces and prevent unauthorized lateral movement. Security+ SY0-701 identifies jump servers as critical in securing high-value systems.

A host-based firewall (E) provides system-level traffic filtering directly on the database server. It allows only trusted IPs, ports, and services to communicate with the database, significantly reducing exposure. This is an essential hardening measure because databases should only accept connections from specific application servers or administrative hosts.

NIDS (B) monitors traffic but does not harden access. Monitoring (C) provides visibility but does not restrict access. A proxy server (D) is not typically used for database access. A WAF (F) protects web applications, not internal database systems.

Thus, A (Jump server) and E (Host-based firewall) are the correct hardening controls.

Monitoring outbound traffic is essential for detecting unauthorized data exfiltration from a system. A new vulnerability that allows malware to move data unauthorizedly would typically attempt to send this data out of the network. By monitoring outbound traffic, security tools can detect unusual data transfers, trigger alerts, and help prevent the exfiltration of sensitive information.

Detailed Explanation:Behavioral analytics tools monitor user actions and detect anomalies that may indicate insider threats, such as unauthorized access or unusual data exfiltration activities. These tools establish baselines for normal behavior and flag deviations.
