failure.
B Restore only the last differential backup.

control system?

How should countermeasures be implemented as part of the recovery phase of incident
response?

Remote control malware was found on a client device, and an unknown attacker was
manipulating the network from afar. The attack resulted in the network switches
reverting to flooding mode, thereby enabling the attacker to eavesdrop on a significant
portion of network communications. After reviewing IDS and traffic logs, you determine
that this was accomplished by an attack utility which generated a constant Ethernet
frames with random source MAC addresses. What can be done to prevent this attack
from occurring in the future?
A Restrict access to DHCP.
B Use a static HOSTS file.
C Use MAC limiting on the switch ports.
D Implement an ARP monitor. - Correct Answers -C
How is quantitative risk analysis performed?
A Through the Delphi technique
B With scenario-based assessments
C Using calculations
D Via employee interviews - Correct Answers -C
What special component on a motherboard can be used to securely store the
encryption key for whole drive encryption?
A CMOS
B RAM
C TPM
D CPU - Correct Answers -C
When is it appropriate to contact law enforcement when an organization experiences a
security breach?
A If a violation is more severe than just breaking company policy rules
B If a breach of security occurs
C If a tolerable or accepted risk is realized
D If an insider uses another employee's credentials - Correct Answers -A
What is the name of a cryptographic attack based on a database of pre-computed hash
values and the original plaintext values?
A Brute force attack
, B Rainbow table attack
C Frequency analysis
D Chosen plaintext attack - Correct Answers -B
What is the purpose of a Security Information and Event Management (SIEM) product?
A To provide real-time logging and analysis of security events
B To define the requirements of security procedures
C To provide event planning guidance for holding industry conferences
D To improve employee security training - Correct Answers -A
How does salting passwords reduce the likelihood that a password cracking attack will
be successful?
A It prevents automated attacks.
B It forces the attacker to focus on one account at a time.
C It triggers an account lockout after a fixed number of false attempts.
D It increases the work load required to become successful. - Correct Answers -D
Which of the following clearance levels or classification labels is not generally used in a
government- or military-based MAC scheme?
A Unclassified
B Confidential
C Top Secret
D Proprietary - Correct Answers -D
You are starting a new website. You want to quickly allow users to begin using your site
without having the hassle of creating a new user account. You set up a one-way trust
federated access link from your website to the three major social networks. Why should
you use a one-way trust in this configuration rather than a two-way trust in this
scenario?
A A one-way trust allows your website to trust the user accounts of the social networks
without requiring the social networks to trust your website.
B Two-way trusts are only valid in private networks and cannot be used across the
Internet.
C A one-way trust allows your website to access the file storage of the social networks.
D A two-way trust would grant the social network administrators full access to your
backend database. - Correct Answers -A
Why should the risks of an organization be reported as defined by enterprise risk
management (ERM)?
