CompTIA Advanced Security Practitioner (Cas-001) 241-270

The Security Manager should suggest creating an IP camera network and deploying a proxy to authenticate users prior to accessing the cameras. This solution would ensure that only authorized users can view the cameras by requiring them to authenticate through the proxy before accessing the camera feed. This would prevent unauthorized people from viewing the video while allowing the security guard desks on different networks to view the cameras securely.

The CPO and the SPN want to evaluate the solutions provided by the three vendors and determine if they can meet the firm's requirements. To do this, they need more detailed information about the vendors' solutions. An RFP (Request for Proposal) is a document that outlines the firm's requirements and asks the vendors to provide detailed proposals on how they will meet those requirements. Therefore, the CISO should submit an RFP to the three submitting firms to gather the necessary information and evaluate their solutions.

The correct answer is to restore the CIO's email from an email server backup and provide whatever is available up to the last 12 months from the subpoena date. This is because the prosecutors have issued a subpoena requesting all the CIO's email from the last 12 months, and it is important to comply with legal requests. Although the corporate retention policy recommends keeping data for no longer than 90 days, the subpoena takes precedence in this situation. Therefore, all available email data should be restored and provided to the prosecutors.

The company must legally provide five years of email data. Although the data retention policy for their industry only requires one year of email data, the fact that there are three years of data on the server and five years of data on the backup tapes means that the company must provide the maximum amount of data available, which is five years.

The recommendation to switch to TLS in the DMZ is based on the fact that the financial company already has end-to-end encryption via SSL in the DMZ. TLS is a more secure and updated version of SSL, so switching to TLS would enhance the security of the DMZ. Implementing NIPS (Network Intrusion Prevention System) on the internal network and HIPS (Host Intrusion Prevention System) on the DMZ would provide additional layers of security to detect and prevent any potential intrusions or attacks on both networks.

Lines 6 and 4 will result in the strongest seed when combined. Line 6 uses network data for entropy, which can provide a high level of randomness and unpredictability. Line 4 uses keyboard data for entropy, which can also contribute to a strong seed. Combining these two sources of entropy will enhance the overall strength of the seed used for cryptographic routing.

The most appropriate method for dealing with this issue going forward would be to provide targeted security awareness training and impose termination for repeat violators. This incident highlights a lack of understanding of security protocols and the potential risks associated with granting unauthorized access to sensitive systems. By providing targeted security awareness training, employees can be educated on the importance of following proper security procedures and the potential consequences of their actions. Additionally, imposing termination for repeat violators sends a strong message that security breaches will not be tolerated, further discouraging similar incidents in the future.

Awareness training is the best option to address the security and risk team's concerns in this scenario. By providing training to the bank staff, they will be educated about the potential risks and threats associated with unintentionally aiding fraud. This will help them to better understand their roles and responsibilities, and enable them to identify and mitigate any suspicious activities or behaviors. Awareness training will also ensure that the staff is aware of the importance of maintaining security measures and following the least privilege principles while building relationships with customers.

The most likely cause of the processing problem is that the Linux file system being used is unable to write files as fast as they can be read by the Java program. This means that the files are being accessed and processed before they are completely written to the disk, resulting in incomplete files and errors. This issue is specific to the Linux file system and is not related to the network infrastructure or devices, as other SAN customers are unaffected. The problem arises due to the large number of small files being written to disk from a network source one file at a time.

A web application firewall (WAF) is designed to protect the infrastructure from various types of attacks. In this case, the correct answer is "SQL Injection, DOM based XSS, HTTP exhaustion." SQL Injection refers to the exploitation of a vulnerability in a web application's database layer, while DOM based XSS (Cross-Site Scripting) is a type of vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. HTTP exhaustion refers to overwhelming a server with a high volume of HTTP requests, causing it to become unresponsive. These three combinations of attacks can be mitigated by a WAF without any customization.

The given answer correctly identifies the management challenges and risks associated with the style of technology lifecycle management described in the question. Replacing servers whenever budget money becomes available can lead to an increased mean time to failure rate of legacy servers, as older hardware may be more prone to failures. Additionally, using servers and desktops from different manufacturers can result in OS variances, making it difficult to manage and maintain a consistent system. Patch availability may also be a challenge, as different hardware and OS versions may require specific patches. Lastly, the ability to restore data to dissimilar hardware can be problematic, as compatibility issues may arise.

Federated IDs have the lowest up front development costs for combining the disparate authentication mechanisms in this scenario. By implementing federated IDs, the company can create a single identity management system that allows users to access multiple databases, web portals, and cloud data sets using a single set of credentials. This eliminates the need to develop and maintain custom authentication mechanisms and schemas for each data store, reducing development costs.

The customer needs the system to generate a pseudo-random number when the existing Java program is invoked. This means that the system should be able to produce a series of numbers without any discernible mathematical progression, as required by the customer's website.

The security team should develop an interconnection policy to establish guidelines and protocols for connecting the newly acquired businesses to the existing corporate network. This will ensure that the integration is done securely and efficiently. Additionally, conducting a risk analysis of each acquired company's networks is important to identify any vulnerabilities or potential security threats that may exist. This will help the security team prioritize their efforts and address any weaknesses in the acquired networks.

The auditor should recommend replacing the SSL certificate on pay.xyz.com as the first step. This is because the SSL certificate was issued to *.xyz.com, which means it is a wildcard certificate that can be used for multiple subdomains. Since many of the internal development servers also use the same certificate, it is important to replace the certificate on the payment server to ensure its security. Additionally, the misplacement of the USB thumb-drive where the certificate was stored poses a potential risk, further emphasizing the need to replace the certificate.

The most important consideration before outsourcing the CRM and marketing/leads management to Company XYZ is to ensure that there are security controls within the contract and the right to audit. This is crucial because it ensures that the sensitive customer data and company information will be protected and that the outsourced company will be held accountable for any security breaches. By having security controls in the contract, Company ABC can establish clear expectations and requirements for data protection. The right to audit provides Company ABC with the ability to assess and verify the security measures implemented by Company XYZ.

Transport encryption should be implemented to achieve the highest level of confidentiality for data on the lab network. Transport encryption ensures that data transmitted over the network is encrypted, protecting it from unauthorized access or interception. This is especially important when sensitive data is being transmitted between different systems or over the internet. Implementing transport encryption will add an extra layer of security to the existing infrastructure design, ensuring that data remains confidential during transmission.

The security engineer is responsible for ensuring that the entire process, from customer input to audit review, functions in a secure manner. This means that the engineer needs to ensure that all steps in the process, including the website front end, shopping cart application, transaction processing, and audit record storage, are secure and protected against potential threats or vulnerabilities. This includes implementing appropriate security controls, encryption, access controls, and monitoring mechanisms to ensure the confidentiality, integrity, and availability of the e-business transactions and audit records.

The hosting company should manage the hypervisor-based firewall while allowing customers to configure their own host-based firewall. This option best meets the requirements because it provides logical separation between customers through the hypervisor-based firewall, which is managed by the hosting company. At the same time, it allows customers to have configuration control over their own host-based firewall, giving them the flexibility and control they desire. This solution satisfies both the need for separation and the option for customers to have configuration control or value-added service from the hosting company.

Device fingerprinting is the method that the security researcher should use to enumerate the ports and protocols in use by the appliance. Device fingerprinting involves analyzing the network traffic or device responses to identify specific characteristics or patterns that can be used to determine the device's operating system, software, or configuration. By performing device fingerprinting, the security researcher can gather information about the ports and protocols being used by the appliance, which is crucial for evaluating its security.

The correct answer is to deploy the following ACL to the HIPS: DENY - TCP - ANY - ANY - 445. By implementing this access control list (ACL) on the host-based intrusion prevention system (HIPS), the security administrator can block any TCP communication on port 445, which is the channel through which the worm is spreading. This will effectively minimize the attack by preventing further communication and distribution of the worm within the organization's network.

The security administrator can conduct a gap analysis to identify any areas where the current controls may be lacking or insufficient. Based on the findings of the gap analysis, the administrator can recommend appropriate non-technical mitigating controls to address the identified gaps. These non-technical controls can include policies, procedures, and training measures. The administrator can then incorporate these new controls into the company's security standard to further enhance security. This approach ensures that security is improved beyond just technical controls and takes into account the overall security posture of the business process.

The correct answer is "Denial of Service; use rate limiting to limit traffic." The explanation for this answer is that the security administrator observed an excessive number of SIP INVITE packets destined for the SIP proxy. This indicates that a Denial of Service (DoS) attack is underway, where the attacker floods the network with a high volume of SIP INVITE packets, causing congestion and preventing legitimate users from placing phone calls. To remediate this attack, rate limiting can be implemented to restrict the amount of traffic allowed to the SIP proxy, ensuring that the network resources are not overwhelmed and legitimate users can make phone calls.

White box testing, performed by the development and security assurance teams, would satisfy the CISO's requirements. This type of testing allows for a thorough examination of the system, as it involves testing the internal workings and code of the application. It can be scripted and has a low risk of impacting system stability. Additionally, since the development team has a deep understanding of the system, they can provide the necessary introspection that a third party may lack.

The CFO's decision to outsource IT architectural functions to multiple providers will have several risk implications. Firstly, the segregation of duties between the providers may adversely impact the strategic architecture of the organization. Secondly, vendor management costs are likely to increase as the organization will now have to manage multiple providers. This may also reduce the organization's flexibility to react to new market conditions. Additionally, internal knowledge of IT systems is likely to decline as providers maintain system documentation. This could hinder future platform development. Lastly, the implementation of security controls and updates may take longer as responsibility crosses multiple boundaries.

The secondary domain in single sign-on needs to trust the primary domain in order to protect the authentication credentials used to verify the end user identity to the secondary domain for authorized use. Additionally, it needs to correctly assert the identity and authentication credentials of the end user.

To manage the risks of new zero-day attacks, it is important for a security manager to create an inventory of applications and maintain a list of critical systems. Creating an inventory of applications helps in identifying and monitoring the software that is being used within the organization, allowing for better vulnerability management. Maintaining a list of critical systems helps prioritize their protection and ensure that necessary security measures are in place to mitigate the risks associated with zero-day attacks.

The ISO should consider providing each department with a virtual firewall and assigning appropriate levels of management for the virtual device. This approach allows for separate networks with independent control of their security boundaries, meeting the requirements of both the R&D and IT support teams. By using virtual firewalls, the ISO can provide the necessary functionality without increasing the hardware footprint within the datacenter. This ensures that each department has its own firewall and can manage it according to their specific needs.

The element in SAML can be provided in the X.509 subject name format, which is a standard format for identifying subjects in X.509 certificates. It can also be provided in the Kerberos principal name format, which is a format used to identify principals in a Kerberos authentication system. Both of these formats are commonly used and supported in SAML implementations for identifying subjects in SAML assertions.

The security engineer would most likely implement establishing an SSH tunnel from the Mac to the Linux server and connecting the VNC to 127.0.0.1. This would secure the connection by encrypting the data transmitted between the Mac and the server, preventing network sniffing and unauthorized access to the password. By using the SSH tunnel, the connection would be secure and the designers can continue accessing the graphical application on the Linux server without compromising security.
