CompTIA Security+ Question D-78

Which of the following BEST represents the goal of a vulnerability assessment?

A. To test how a system reacts to known threats
B. To reduce the likelihood of exploitation
C. To determine the system’s security posture
D. To analyze risk mitigation strategies

Answer: C

Explanation:
A vulnerability scan is the process of scanning the network and/or I.T. infrastructure for threats and vulnerabilities. The threats and vulnerabilities are then evaluated in a risk assessment and the necessary actions taken to resolve and vulnerabilities. A vulnerability scan scans for known weaknesses such as missing patches or security updates.

A vulnerability scan is the automated process of proactively identifying security vulnerabilities of computing systems in a network in order to determine if and where a system can be exploited and/or threatened. While public servers are important for communication and data transfer over the Internet, they open the door to potential security breaches by threat agents, such as malicious hackers. Vulnerability scanning employs software that seeks out security flaws based on a database of known flaws, testing systems for the occurrence of these flaws and generating a report of the findings that an individual or an enterprise can use to tighten the network’s security.

CompTIA Security+ Question D-29

Ann, a security analyst, is preparing for an upcoming security audit. To ensure that she identifies unapplied security controls and patches without attacking or compromising the system, Ann would use which of the following?

A. Vulnerability scanning
B. SQL injection
C. Penetration testing
D. Antivirus update

CompTIA Security+ Question A-83

A security administrator wants to perform routine tests on the network during working hours when certain applications are being accessed by the most people. Which of the following would allow the security administrator to test the lack of security controls for those applications with the least impact to the system?

A. Penetration test
B. Vulnerability scan
C. Load testing
D. Port scanner

CompTIA Security+ Question A-3

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

Answer: A

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.

CompTIA Network+ Question C-85

A network technician has set up an FTP server for the company to distribute software updates for their products. Each vendor is provided with a unique username and password for security. Several vendors have discovered a virus in one of the security updates. The company tested all files before uploading them but retested the file and found the virus. Which of the following could the technician do for vendors to validate the proper security patch?

A. Use TFTP for tested and secure downloads
B. Require biometric authentication for patch updates
C. Provide an MD5 hash for each file
D. Implement a RADIUS authentication

Correct Answer: C

Explanation:
If we put an MD5 has for each file we can see if the file has been changed or not.
MD5 is an algorithm that is used to verify data integrity through the creation of a 128-bit message digest from data input (which may be a message of any length) that is claimed to be as unique to that specific data as a fingerprint is to the specific individual.
