During the containment phase, the immediate response to an incident involves limiting its scope and magnitude, which includes preserving evidence. This is crucial for a subsequent forensic analysis and for learning lessons from the incident to prevent future occurrences.

References = The containment phase is part of the incident response process as outlined in ISACA’s resources, which include steps such as detection and analysis, containment, eradication, recovery, and post-incident activities12.

The main objective of an intrusion detection system (IDS) policy is to establish the criteria for what constitutes an intrusion event and the reporting requirements once such an event is detected. This includes defining what activities are considered anomalies, ensuring that security breaches are identified, and specifying how and to whom these incidents should be reported. The policy sets the foundation for how intrusions are detected, assessed, and managed within an organization’s network infrastructure1.

References: ISACA’s resources on cybersecurity highlight the importance of having a clear IDS policy that outlines the detection and response procedures for security incidents. Such a policy is crucial for the effective monitoring and management of potential security breaches, ensuring that they are promptly identified and addressed1.

Key risk indicators (KRIs) are metrics that can provide an early signal of increasing risk exposures for an organization. KRIs are designed to measure and predict potential losses, and they help in identifying trends that could lead to future risks. They aredifferent from Key Performance Indicators (KPIs), which measure the performance related to the achievement of strategic goals. KRIs, on the other hand, are specifically focused on risk and are used to monitor changes in the level of risk exposure.

References: The information is supported by ISACA’s resources, which state that KRIs with thresholds and corresponding trigger actions can enable companies to gain visibility into risks before they occur. These metrics best position enterprises to deal with substantial cyber risks associated with digital transformation and implementing emerging technologies1.

The second line of defense in cybersecurity includes risk management monitoring, and measurement of controls. This is because the second line of defense is responsible for ensuring that the first line of defense (the operational managers and staff who own and manage risks) is effectively designed and operating as intended. The second line of defense also provides guidance, oversight, and challenge to the first line of defense. The other options are not part of the second line of defense, but rather belong to the first line of defense (A), the third line of defense C, or an external service provider (D).

A full backup involves copying all data to the backup storage location. It is the most comprehensive type of backup, which makes it the most time-consuming. This is because every file and folder is included in the backup, regardless of when it was last modified.

Incremental and differential backups are faster because they only copy data that has changed since the last backup. Incremental backups include data that has changed since the last incremental backup, while differential backups include data that has changed since the last full backup.

Offsite backups refer to the location where the backup is stored rather than the method of backup, so the time required can vary widely depending on the specific circumstances.

References: The information provided here is based on standard backup practices and principles, which are likely to be consistent with those found in ISACA’s Cybersecurity Audit resources. For specific references, please consult the ISACA Cybersecurity Audit Manual or related study guides12.

The risk of an evil twin attack on mobile devices is PRIMARILY due to the use of generic names that mobile devices will accept without verification. An evil twin attack is a type of wireless network attack where an attacker sets up a rogue access point that mimics a legitimate one. The attacker can then lure unsuspecting users to connect to the rogue access point and intercept their data or launch further attacks. Mobile devices are vulnerable to evil twin attacks because they often use generic names for their wireless networks, such as “Free WiFi” or “Public Hotspot”. These names can be easily spoofed by an attacker and accepted by mobile devices without verifying the identity or security of the access point.

In the context of network communications, the two types of attack vectors are ingress and egress. Ingress refers to the unauthorized entry or access to a network, which can include various forms of cyberattacks aimed at penetrating network defenses. Egress,on the other hand, involves the unauthorized transmission of data out of a network, often as part of data exfiltration efforts by attackers1.

References: The ISACA Cybersecurity Fundamentals Glossary defines attack vectors in network communications as ingress and egress, which align with the options provided in the question1.

Hacktivists are politically motivated hackers who target specific individuals or organizations to achieve various ideological ends. They may use various methods such as defacing websites, launching denial-of-service attacks, leaking confidential information, or spreading propaganda to advance their causes or protest against perceived injustices.

In cloud computing, the type of hosting that is MOST appropriate for a large organization that wants greater control over the environment is private hosting. Private hosting is a type of cloud service model where the cloud infrastructure is dedicated to a single organization and hosted either on-premise or off-premise by a third-party provider. Private hosting offers more control over the security, performance, customization, and compliance of the cloud environment than other types of hosting.

A security setting that locks a profile after a certain number of unsuccessful login attempts is designed to mitigate brute force attacks. In such attacks, an adversary systematically tries numerous combinations of usernames and passwords to gain unauthorized access. By locking the account after several failed attempts, it prevents the attacker from continuing to try different password combinations, thus thwarting the brute force method.

References = This security measure is a common recommendation in cybersecurity practices, including those suggested by ISACA, to protect against brute force attacks. It is an effective control to prevent attackers from continuously attempting to guess a user’s credentials123.
