With dedication and strategic preparation, you'll be well on your way to achieving your CySA+ certification.
Which of the following refers to the likelihood of a vulnerability appearing again after it has been remediated?
Recurrence refers to the likelihood of a vulnerability appearing again after it has been remediated. A security incident is an event that results in unauthorized access or damage to a system or data. Access control is the method of regulating who or what can view or use resources in a computing environment. A data breach refers to an incident where information is accessed without authorization.

Your organization is concerned about potential leaks of sensitive data. Which technology should be deployed to identify and prevent unauthorized access to such data?
Data Loss Prevention (DLP) solutions play a crucial role in protecting an organization's sensitive information from unauthorized exposure. By identifying critical data, monitoring how it moves and is used across the network, and preventing unsanctioned access or transmission, DLP tools offer comprehensive protection against data breaches. These technologies can mitigate risks from both internal and external threats, safeguarding data whether it's at rest, in use, or in transit. While firewalls can prevent unauthorized network access, they do not specifically identify or protect sensitive data like DLP does. Anti-virus software primarily focuses on identifying and removing malware and doesn't offer specific protections for sensitive data like DLP. Encryption can secure data in transit or at rest but doesn't actively identify or prevent unauthorized access to sensitive data like DLP.

Your organization has recently migrated to a SaaS provider for its enterprise resource planning (ERP) software. Before this migration, a weekly port scan was conducted to help validate the on-premise systems' security. Which of the following actions should you take to validate the security of the cloud-based solution?
The best option is to utilize vendor testing and audits in a cloud-based environment. Most SaaS providers will not allow customers to conduct their own port scans or vulnerability scans against the SaaS service. This means you cannot scan using a VPN connection, utilize different scanning tools, or hire a third-party contractor to scan on your behalf.

If an attacker can compromise an Active Directory domain by utilizing an attack to grant administrative access to the domain controllers for all domain members, which type of attack is being used?
A golden ticket is a Kerberos ticket that can grant other tickets in an Active Directory environment. Attackers who can create a golden ticket can use it to grant administrative access to other domain members, even to domain controllers. Pass the Hash (PtH) is the process of harvesting an account's cached credentials when the user logs in to a single sign-on (SSO) system. This would then allow the attacker to use the credentials on other systems, as well. Lateral movement is an umbrella term for a variety of attack types. Attackers can extend their lateral movement by a great deal if they can compromise host credentials. Pivoting is a process similar to lateral movement. When attackers pivot, they compromise one central host (the pivot) that allows them to spread out to other hosts that would otherwise be inaccessible.

What remediation strategies are the MOST effective in reducing the risk to an embedded ICS from a network-based compromise? (Select TWO)
Segmentation is the best method to reduce the risk to an embedded ICS system from a network-based compromise. Additionally, you could disable unused services to reduce the footprint of the embedded ICS. Many of these embedded ICS systems have a large number of default services running. So, by disabling the unused services, we can better secure these devices. By segmenting the devices off the main portion of the network, we can also better protect them. A NIDS might detect an attack or compromise, but it would not reduce the risk of the attack succeeding since it can only detect it. Patching is difficult for embedded ICS devices since they usually rely on customized software applications that rarely provide updates.

In the 2017 Equifax breach, the credit reporting company itself had vast amounts of sensitive personal data of consumers exposed due to a flaw in their Apache Struts web-application software. In the context of the Diamond Model of Intrusion Analysis, who does Equifax represent?
Infrastructure refers to the physical and virtual resources used in the attack, not the targeted entity. For support or reporting issues, include Question ID: 64790f25a12e9833fb7050ca in your ticket. Thank you.
Which of the following are valid concerns when migrating to a serverless architecture? (SELECT THREE)
Serverless is a modern design pattern for service delivery. With serverless, all the architecture is hosted within a cloud, but unlike “traditional” virtual private cloud (VPC) offerings, services such as authentication, web applications, and communications aren’t developed and managed as applications running on servers located within the cloud. Instead, the applications are developed as functions and microservices, each interacting with other functions to facilitate client requests. There is a heavy dependency on the cloud service provider in a serverless architecture system since all of the back-end infrastructure's patching and management functions are done by them. An organization using such an architecture would still need to prevent compromise of the user endpoints, though the cloud service provider does not manage these. Another concern with serverless architectures is that there are limited options for disaster recovery if service provisioning fails. Patching of backend infrastructure is eliminated because the infrastructure is eliminated with serverless architectures. Once migration is complete, there are no physical servers to manage, which reduces the workload on your system administration teams.

What command should a forensic analyst use to make a forensic disk image of a hard drive?
The dd tool is used to make bit by bit copies of a disk, drive, or partition. Once the image is created using dd, a hash of the file should be made and placed into evidence to validate the integrity of the disk image that was created. This will ensure that no modification occurs between the collection and analysis of the disk image. The wget command is a command-line utility for downloading files from the Internet. The touch command is a standard command used in the UNIX/Linux operating system used to create, change, and modify timestamps of a file. The rm command is used to delete one or more files or directories. For support or reporting issues, include Question ID: 63fe08c43b7322449ddbde99 in your ticket. Thank you.
Which operating system feature is designed to detect malware that is loaded early in the system startup process or before the operating system can load itself?
Measured boot is a feature where a log of all boot actions is taken and stored in a trusted platform module for later retrieval and analysis by anti-malware software on a remote server. Master boot record analysis is used to capture the hard disk's required information to support a forensic investigation. It would not detect malware during the system's boot-up process. Startup control would be used to determine which programs will be loaded when the operating system is initially booted, but this would be too late to detect malware loaded during the pre-startup and boot process. Advanced anti-malware solutions are programs that are loaded within the operating system. Therefore, they are loaded too late in the startup process to be effective against malicious boot sector viruses and other BIOS/UEFI malware variants.

During your annual cybersecurity awareness training in your company, the instructor states that employees should be careful about what information they post on social media. According to the instructor, if you post too much personal information on social media, such as your name, birthday, hometown, and other personal details, it is much easier for an attacker to conduct which type of attack to break your passwords?
A cognitive password is a form of knowledge-based authentication that requires a user to answer a question, presumably something they intrinsically know, to verify their identity. If you post a lot of personal information about yourself online, this type of password can easily be bypassed. For example, during the 2008 elections, Vice Presidential candidate Sarah Palin's email account was hacked because a high schooler used the "reset my password" feature on Yahoo's email service to reset her password using the information that was publicly available about Sarah Palin (like her birthday, high school, and other such information).
