Section: Protection of Information Assets
Explanation:
Senior management should establish the acceptable risk level, since they have the ultimate or final
responsibility for the effective and efficient operation of the organization. Choices A, C and D should act as
advisors to senior management in determining an acceptable risk level.

Comprehensive and Detailed Step-by-Step Explanation:
Thebiggest riskin cloud migration isdata security, especially unauthorized access by the cloud provider.
Option A (Correct):The cloud providermanages and stores organizational data, meaning that abreach, insider threat, or improper accessposes amajor risk. Properencryption and access controlsare critical.
Option B (Incorrect):Whilemulti-tenancy risks exist, cloud providers typically implement strongisolation mechanismsbetween clients.
Option C (Incorrect):Increased dependency on the provider is aconcern, but the impact depends onservice agreements and redundancy measures.
Option D (Incorrect):Limiting the right to audit is acompliance issue, butdata security risksare more critical.

Explanation:
Mitigating the risk and impact of a disaster or business interruption usually takes priority over transferring risk to a third party such as an insurer.

Explanation/Reference:
Host Based IDS resides on important systems like database, critical servers and monitors various internal
resources of an operating system.
Also, you should know below mentioned categories and types of IDS for CISA exam
An IDS works in conjunction with routers and firewall by monitoring network usage anomalies.
Broad categories of IDS include:
1. Network Based IDS
2. Host Based IDS
Network Based IDS
They identify attack within the monitored network and issue a warning to the operator.
If a network based IDS is placed between the Internet and the firewall, it will detect all the attack attempts
whether or not they enter the firewall
Network Based IDS are blinded when dealing with encrypted traffic
Host Based IDS
They are configured for a specific environment and will monitor various internal resources of the operating
system to warn of a possible attack.
They can detect the modification of executable programs, detect the detection of files and issue a warning
when an attempt is made to use a privilege account.
They can monitor traffic after it is decrypted and they supplement the Network Based IDS.
Types of IDS includes:
Statistical Based IDS - This system needs a comprehensive definition of the known and expected behavior
of system
Neural Network - An IDS with this feature monitors the general patterns of activity and traffic on the
network, and create a database. This is similar to statistical model but with added self-learning functionality.
Signature Based IDS - These IDS system protect against detected intrusion patterns. The intrusive pattern
they can identify are stored in the form of signature.
The following were incorrect answers:
The other types of IDS mentioned in the options do not resides on important systems like database and
critical servers
