A technician has implemented a system in which all workstations on the network will receive security updates on the same schedule. Which of the following
concepts does this illustrate?
A.
Patch management
B.
Application hardening
C.
White box testing
D.
Black box testing
Explanation:
Patch management is the process of maintaining the latest source code for applications and operating systems by applying the latest vendor updates. This helps
protect a systems from newly discovered attacks and vulnerabilities. A part of patch management is testing the effects of vendor updates on a test system before
applying the updates on a production system, and scheduling updates.
Incorrect Answers:
B: Hardening is the process of securing a system by reducing its surface of vulnerability. Reducing the surface of vulnerability typically includes removing or
disabling unnecessary functions and features, removing or disabling unnecessary user accounts, disabling unnecessary protocols and ports, and disabling
unnecessary services.
C: White box testing is a form of penetration testing in which the tester has significant knowledge of the system and how it functions. This simulates an attack from
an insider.
D: Black box testing is a form of penetration testing in which the tester has absolutely no knowledge of the system or it how it functions. This simulates an attack
from an outsider.Stewart, James Michael, CompTIA Security+ Review Guide, Sybex, Indianapolis, 2014, pp 221, 231-232
