• D. Automate alerting to IT support for phone system outages.

Answer: C

Explanation:
Enabling dashboards for service status monitoring is the best action to support rapid incident response. The table shows various services with different risk, criticality, and alert severity ratings. To ensure timely and effective incident response, real-time visibility into the status of these services is crucial.
Why Dashboards for Service Status Monitoring?
* Real-time Visibility: Dashboards provide an at-a-glance view of the current status of all critical services, enabling rapid detection of issues.
* Centralized Monitoring: A single platform to monitor the status of multiple services helps streamline incident response efforts.
* Proactive Alerting: Dashboards can be configured to show alerts and anomalies immediately, ensuring that incidents are addressed as soon as they arise.
* Improved Decision Making: Real-time data helps incident response teams make informed decisions quickly, reducing downtime and mitigating impact.
Other options, while useful, do not offer the same level of comprehensive, real-time visibility and proactive alerting:
* A. Automate alerting to IT support for phone system outages: This addresses one service but does not provide a holistic view.
* C. Send emails for failed log-in attempts on the public website: This is a specific alert for one type of issue and does not cover all services.
* D. Configure automated isolation of human resources systems: This is a reactive measure for a
* specific service and does not provide real-time status monitoring.

NEW QUESTION # 50
A company's help desk is experiencing a large number of calls from the finance department slating access issues to www bank com The security operations center reviewed the following security logs:

Which of the following is most likely the cause of the issue?

• A. The DNS record has been poisoned.
• B. Recursive DNS resolution is failing
• C. DNS traffic is being sinkholed.
• D. The DNS was set up incorrectly.

Answer: C

Explanation:
Sinkholing, or DNS sinkholing, is a method used to redirect malicious traffic to a safe destination. This technique is often employed by security teams to prevent access to malicious domains by substituting a benign destination IP address.
In the given logs, users from the finance department are accessing www.bank.com and receiving HTTP status code 495. This status code is typically indicative of a client certificate error, which can occur if the DNS traffic is being manipulated or redirected incorrectly. The consistency in receiving the same HTTP status code across different users suggests a systematic issue rather than an isolated incident.
* Recursive DNS resolution failure (A) would generally lead to inability to resolve DNS at all, not to a specific HTTP error.
* DNS poisoning (B) could result in users being directed to malicious sites, but again, would likely result in a different set of errors or unusual activity.
* Incorrect DNS setup (D) would likely cause broader resolution issues rather than targeted errors like the one seen here.
By reviewing the provided data, it is evident that the DNS traffic for www.bank.com is being rerouted improperly, resulting in consistent HTTP 495 errors for the finance department users. Hence, the most likely cause is that the DNS traffic is being sinkholed.

NEW QUESTION # 54
A security analyst wants to use lessons learned from a poor incident response to reduce dwell lime in the future The analyst is using the following data points

Which of the following would the analyst most likely recommend?

• A. Allowing TRACE method traffic to enable better log correlation
• B. utilizing allow lists on the WAF for all users using GFT methods
• C. Adjusting the SIEM to alert on attempts to visit phishing sites
• D. Enabling alerting on all suspicious administrator behavior

Answer: D

Explanation:
In the context of improving incident response and reducing dwell time, the security analyst needs to focus on proactive measures that can quickly detect and alert on potential security breaches. Here's a detailed analysis of the options provided:
A: Adjusting the SIEM to alert on attempts to visit phishing sites: While this is a useful measure to prevent phishing attacks, it primarily addresses external threats and doesn't directly impact dwell time reduction, which focuses on the time a threat remains undetected within a network.
B: Allowing TRACE method traffic to enable better log correlation: The TRACE method in HTTP is used for debugging purposes, but enabling it can introduce security vulnerabilities. It's not typically recommended for enhancing security monitoring or incident response.
C: Enabling alerting on all suspicious administrator behavior: This option directly targets the potential misuse of administrator accounts, which are often high-value targets for attackers. By monitoring and alerting on suspicious activities from admin accounts, the organization can quickly identify and respond to potential breaches, thereby reducing dwell time significantly. Suspicious behavior could include unusual login times, access to sensitive data not usually accessed by the admin, or any deviation from normal behavior patterns.
This proactive monitoring is crucial for quick detection and response, aligning well with best practices in incident response.
D: Utilizing allow lists on the WAF for all users using GET methods: This measure is aimed at restricting access based on allowed lists, which can be effective in preventing unauthorized access but doesn't specifically address the need for quick detection and response to internal threats.

• G. The srvo1 A record must be changed to a type CNAME record pointing to the email server

Answer: E,F

Explanation:
The security engineer should modify the following to fix the email migration issues:
* Email CNAME Record: The email CNAME record must be changed to a type A record pointing to
192.168.1.10. This is because CNAME records should not be used where an IP address (A record) is
* required. Changing it to an A record ensures direct pointing to the correct IP.
* TXT Record for DMARC: The TXT record must be changed to "v=dmarc ip4:192.168.1.10 include com -all". This ensures proper configuration of DMARC (Domain-based Message Authentication, Reporting
& Conformance) to include the correct IP address and the email service provider domain.
* DMARC: Ensuring the DMARC record is correctly set up helps in preventing email spoofing and phishing, aligning with email security best practices.

Which of the following is the best way to fix this issue?

• A. Blocking all non-essential pons
• B. Rewriting any legacy web functions
• C. Disabling all deprecated ciphers
• D. Discontinuing the use of self-signed certificates

Answer: D

Explanation:
The error message "NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM" indicates that the web browser is rejecting the certificate because it uses a weak signature algorithm. This commonly happens with self-signed certificates, which often use outdated or insecure algorithms.
Why Discontinue Self-Signed Certificates?
* Security Compliance: Modern browsers enforce strict security standards and may reject certificates that do not comply with these standards.
* Trusted Certificates: Using certificates from a trusted Certificate Authority (CA) ensures compliance with security standards and is less likely to be flagged as insecure.
* Weak Signature Algorithm: Self-signed certificates might use weak algorithms like MD5 or SHA-1, which are considered insecure.
Other options do not address the specific cause of the certificate error:
* A. Rewriting legacy web functions: Does not address the certificate issue.
* B. Disabling deprecated ciphers: Useful for improving security but not related to the certificate error.
* C. Blocking non-essential ports: This is unrelated to the issue of certificate validation.

A financial technology firm works collaboratively with business partners in the industry to share threat intelligence within a central platform This collaboration gives partner organizations the ability to obtain and share data associated with emerging threats from a variety of adversaries Which of the following should the organization most likely leverage to facilitate this activity? (Select two).

• A. ATTACK
• B. YAKA
• C. STIX
• D. CWPP
• E. JTAG
• F. TAXII

Answer: C,F

Explanation:
* D. STIX (Structured Threat Information eXpression): STIX is a standardized language for representing threat information in a structured and machine-readable format. It facilitates the sharing of threat intelligence by ensuring that data is consistent and can be easily understood by all parties involved.
* E. TAXII (Trusted Automated eXchange of Indicator Information): TAXII is a transport mechanism that enables the sharing of cyber threat information over a secure and trusted network. It works in conjunction with STIX to automate the exchange of threat intelligence among organizations.
Other options:
* A. CWPP (Cloud Workload Protection Platform): This focuses on securing cloud workloads and is not directly related to threat intelligence sharing.
* B. YARA: YARA is used for malware research and identifying patterns in files, but it is not a platform for sharing threat intelligence.
* C. ATT&CK: This is a knowledge base of adversary tactics and techniques but does not facilitate the sharing of threat intelligence data.
* F. JTAG: JTAG is a standard for testing and debugging integrated circuits, not related to threat intelligence.

NEW QUESTION # 64
A security analyst is reviewing the following authentication logs:

Which of the following should the analyst do first?

• A. Disable User1's account
• B. Disable User12's account
• C. Disable User2's account
• D. Disable User8's account

Answer: A

Explanation:
Based on the provided authentication logs, we observe that User1's account experienced multiple failed login attempts within a very short time span (at 8:01:23 AM on 12/15). This pattern indicates a potential brute-force attack or an attempt to gain unauthorized access. Here's a breakdown of why disabling User1's account is the appropriate first step:
* Failed Login Attempts: The logs show that User1 had four consecutive failed login attempts:
* VM01 at 8:01:23 AM
* VM08 at 8:01:23 AM
* VM01 at 8:01:23 AM
* VM08 at 8:01:23 AM
* Security Protocols and Best Practices: According to CompTIA Security+ guidelines, multiple failed login attempts within a short timeframe should trigger an immediate response to prevent further potential unauthorized access attempts. This typically involves temporarily disabling the account to stop ongoing brute-force attacks.
* Account Lockout Policy: Implementing an account lockout policy is a standard practice to thwart brute-force attacks. Disabling User1's account will align with these best practices and prevent further failed attempts, which might lead to successful unauthorized access if not addressed.

By addressing User1's account first, we effectively mitigate the immediate threat of a brute-force attack, ensuring that further investigation can be conducted without the risk of unauthorized access continuing during the investigation period.

NEW QUESTION # 65
A vulnerability can on a web server identified the following:

Which of the following actions would most likely eliminate on path decryption attacks? (Select two).

• A. Disallowing cipher suites that use ephemeral modes of operation for key agreement
• B. Increasing the key length to 256 for TLS_RSA_WITH_AES_128_CBC_SHA
• C. Removing support for CBC-based key exchange and signing algorithms
• D. Adding TLS_ECDHE_ECDSA_WITH_AE3_256_GCMS_HA256
• E. Implementing HIPS rules to identify and block BEAST attack attempts
• F. Restricting cipher suites to only allow TLS_RSA_WITH_AES_128_CBC_SHA

Answer: C,D

Explanation:
On-path decryption attacks, such as BEAST (Browser Exploit Against SSL/TLS) and other related vulnerabilities, often exploit weaknesses in the implementation of CBC (Cipher Block Chaining) mode. To mitigate these attacks, the following actions are recommended:
* B. Removing support for CBC-based key exchange and signing algorithms: CBC mode is vulnerable to certain attacks like BEAST. By removing support for CBC-based ciphers, you can eliminate one of the primary vectors for these attacks. Instead, use modern cipher modes like GCM (Galois/Counter Mode) which offer better security properties.
* C. Adding TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA256: This cipher suite uses Elliptic Curve Diffie-Hellman Ephemeral (ECDHE) for key exchange, which provides perfect forward secrecy.
It also uses AES in GCM mode, which is not susceptible to the same attacks as CBC. SHA-256 is a strong hash function that ensures data integrity.

NEW QUESTION # 66
An incident response team is analyzing malware and observes the following:
* Does not execute in a sandbox
* No network loCs
* No publicly known hash match
* No process injection method detected
Which of the following should the team do next to proceed with further analysis?

• A. Check for an anti-virtualization code in the sample
• B. Use an online vims analysis tool to analyze the sample
• C. Utilize a new deployed machine to run the sample.
• D. Search oilier internal sources for a new sample.

Answer: A

Explanation:
Malware that does not execute in a sandbox environment often contains anti-analysis techniques, such as anti-virtualization code. This code detects when the malware is running in a virtualized environment and alters its behavior to avoid detection. Checking for anti-virtualization code is a logical next step because:
* It helps determine if the malware is designed to evade analysis tools.
* Identifying such code can provide insights into the malware's behavior and intent.
* This step can also inform further analysis methods, such as running the malware on physical hardware.
