NEW QUESTION # 308
A security architect is mitigating a vulnerability that previously led to a web application data breach. An analysis into the root cause of the issue finds the following:
An administrator's account was hijacked and used on several Autonomous System Numbers within 30 minutes.
All administrators use named accounts that require multifactor authentication.
Single sign-on is used for all company applications.Which of the following should the security architect do to mitigate the issue?
Answer: A
Explanation:
Comprehensive and Detailed
The hijacked administrator account was used across multiple ASNs (indicating different network locations) in a short time, despite MFA and SSO. This suggests a stolen session or token misuse. Let's analyze:
A . Token theft detection with lockouts:Useful for detecting stolen SSO tokens, but it's reactive and may not prevent initial misuse across networks.
B . Context-based authentication:This adds real-time checks (e.g., geolocation, IP changes) to verify login attempts. Given the rapid ASN changes, this proactively mitigates the issue by challenging suspicious logins, aligning with CAS-005's focus on adaptive security.
C . Decentralize accounts:This removes SSO, increasing complexity and weakening MFA enforcement, which isn't practical or secure.
NEW QUESTION # 309
An organization is planning for disaster recovery and continuity ofoperations, and has noted the following relevant findings:
1. A natural disaster may disrupt operations at Site A, which would then cause an evacuation. Users are unable to log into the domain from-their workstations after relocating to Site B.
2. A natural disaster may disrupt operations at Site A, which would then cause the pump room at Site B to become inoperable.
3. A natural disaster may disrupt operations at Site A, which would then cause unreliable internet connectivity at Site B due to route flapping.
INSTRUCTIONS
Match each relevant finding to the affected host by clicking on the host name and selecting the appropriate number.
For findings 1 and 2, select the items that should be replicated to Site B. For finding 3, select the item requiring configuration changes, then select the appropriate corrective action from the drop-down menu.
Answer:
Explanation:
See the complete solution below in Explanation:
Explanation:
Matching Relevant Findings to the Affected Hosts:
Finding 1:
Affected Host: DNS
Reason: Users are unable to log into the domain from their workstations after relocating to Site B, which implies a failure in domain name services that are critical for user authentication and domain login.
Finding 2:
Affected Host: Pumps
Reason: Thepump room at Site B becoming inoperable directly points to the critical infrastructure components associated with pumping operations.
Finding 3:
Affected Host: VPN Concentrator
Reason: Unreliable internet connectivity at Site B due to route flapping indicates issues with network routing, which is often managed by VPN concentrators that handle site-to-site connectivity.
Corrective Actions for Finding 3:
Finding 3 Corrective Action:
Action: Modify the BGP configuration
Reason: Route flapping is often related to issues with Border Gateway Protocol (BGP) configurations.
Adjusting BGP settings can stabilize routes and improve internet connectivity reliability.
Replication to Site B for Finding 1:
Affected Host: DNS
Domain Name System (DNS) services are essential for translating domain names into IP addresses, allowing users to log into the network. Replicating DNS services ensures that even if Site A is disrupted, users at Site B can still authenticate and access necessary resources.
Replication to Site B for Finding 2:
Affected Host: Pumps
The operation of the pump room is crucial for maintaining various functions within the infrastructure.
Replicating the control systems and configurations for the pumps at Site B ensures that operations can continue smoothly even if Site A is affected.
Configuration Changes for Finding 3:
Affected Host: VPN Concentrator
Route flapping is a situation where routes become unstable, causing frequent changes in the best path for data to travel. This instability can be mitigated by modifying BGP configurations to ensure more stable routing.
VPN concentrators, which manage connections between sites, are typically configured with BGP for optimal routing.

CompTIA Security+ Study Guide: This guide provides detailed information on disaster recovery and continuity of operations, emphasizing the importance of replicating critical services and making necessary configuration changes to ensure seamless operation during disruptions.
CompTIA Security+ Exam Objectives: These objectives highlight key areas in disaster recovery planning, including the replication of critical services and network configuration adjustments.
Disaster Recovery and Business Continuity Planning (DRBCP): This resource outlines best practices for ensuring that operations can continue at an alternate site during a disaster, including the replication of essential services and network stability measures.
By ensuring that critical services like DNS and control systems for pumps are replicated at the alternate site, and by addressing network routing issues through proper BGP configuration, the organization can maintain operational continuity and minimize the impact of natural disasters on their operations.
NEW QUESTION # 310
A security analyst Detected unusual network traffic related to program updating processes The analyst collected artifacts from compromised user workstations. The discovered artifacts were binary files with the same name as existing, valid binaries but. with different hashes which of the following solutions would most likely prevent this situation from reoccurring?
Answer: D
Explanation:
Implementing digital signatures ensures the integrity and authenticity of software binaries. When a binary is digitally signed, any tampering with the file (e.g., replacing it with a malicious version) would invalidate the signature. This allows systems to verify the origin and integrity of binaries before execution, preventing the execution of unauthorized or compromised binaries.
* A. Improving patching processes: While important, this does not directly address the issue of verifying the integrity of binaries.
* B. Implementing digital signatures: This ensures that only valid, untampered binaries are executed, preventing attackers from substituting legitimate binaries with malicious ones.
* C. Performing manual updates via USB ports: This is not practical and does not scale well, especially in large environments.
* D. Allowing only files from internal sources: This reduces the risk but does not provide a mechanism to verify the integrity of binaries.

NEW QUESTION # 312
During the course of normal SOC operations, three anomalous events occurred and were flagged as potential IoCs. Evidence for each of these potential IoCs is provided.
INSTRUCTIONS
Review each of the events and select the appropriate analysis and remediation options for each IoC.
Answer:
Explanation:
See the complete solution below in Explanation:
Explanation:
Analysis and Remediation Options for Each IoC:
IoC 1:
Evidence:
Source: Apache_httpd
Type: DNSQ
Dest: @10.1.1.1:53,@10.1.2.5
Data: update.s.domain, CNAME 3a129sk219r9slmfkzzz000.s.domain, 108.158.253.253 Analysis:
Analysis: The service is attempting to resolve a malicious domain.
Reason: The DNS queries and the nature of the CNAME resolution indicate that the service is trying to resolve potentially harmful domains, which is a common tactic used by malware to connect to command-and- control servers.
Remediation:
Remediation: Implement a blocklist for known malicious ports.
Reason: Blocking known malicious domains at the DNS level prevents the resolution of harmful domains, thereby protecting the network from potential connections to malicious servers.
IoC 2:
Evidence:
Src: 10.0.5.5
Dst: 10.1.2.1, 10.1.2.2, 10.1.2.3, 10.1.2.4, 10.1.2.5
Proto: IP_ICMP
Data: ECHO
Action: Drop
Analysis:
Analysis: Someone is footprinting a network subnet.
Reason: The repeated ICMP ECHO requests to different addresses within a subnet indicate that someone is scanning the network to discover active hosts, a common reconnaissance technique used by attackers.
Remediation:
Remediation: Block ping requests across the WAN interface.
Reason: Blocking ICMP ECHO requests on the WAN interface can prevent attackers from using ping sweeps to gather information about the network topology and active devices.
IoC 3:
Evidence:
Proxylog:
GET /announce?info_hash=%01dff%27f%21%10%c5%wp%4e%1d%6f%63%3c%49%6d & peer_id%
