NEW QUESTION # 72
A restaurant distribution center recently suffered a password spray attack targeting the Cisco Secure Firepower Threat Defense VPN headend. The attack attempts to gain unauthorized access by trying common passwords across many accounts. The attack poses a significant security threat to the organization's remote access infrastructure. To enhance the security of the VPN setup and minimize the risk of similar attacks in the future, the IT security team must implement effective mitigation measures. Which technique effectively reduces the risk of this type of attack?
Answer: A
Explanation:
In the context of Designing Cisco Security Infrastructure, protecting Remote Access VPN (RAVPN) against brute-force and password spray attacks is a critical objective. On Cisco Firepower Threat Defense (FTD) and Adaptive Security Appliance (ASA) platforms, theDefaultWEBVPNGroupandDefaultRAGroupare the landing points for any connection request that does not specify a valid Group Alias or Group URL. Attackers frequently target these default profiles because they are often left with "None" as the authentication method, allowing the attacker to probe for valid usernames without immediate rejection.
By selectingOption D, the security designer ensures that any attempt to access the VPN via these default profiles requires valid AAA credentials. According to Cisco's hardened design guides, it is best practice to point these default profiles to a "sinkhole" AAA server or a local database with no users. This forces the password spray attack to fail at the initial authentication phase before any sensitive information is leaked or unauthorized access is granted. While Option A (ACLs) provides a temporary fix, it is ineffective against distributed attacks using rotating IP addresses. Option B (Disabling aliases) is a good obfuscation technique but doesn't stop an attacker from hitting the default profile. Option D provides a structural mitigation that aligns with theCisco SAFEarchitectural principle of reducing the attack surface by securing every possible entry vector into the private infrastructure.
NEW QUESTION # 73
Refer to the exhibit. A retail company recently deployed a file inspection feature using secure endpoint. The file inspection must detect and prevent the execution of malicious files on machines. During testing, logs showed that certain malicious files are still being executed despite the presence of the security measure. To understand why the threats are not being blocked, it is essential to investigate the configuration of secure endpoint policies. Which configuration is allowing the files to execute?
Answer: C
Explanation:
The exhibit shows that the malicious file was detected but not quarantined with the note "In audit only mode." This indicates that the secure endpoint policy was set to audit mode, which only logs detections instead of blocking execution. To prevent malicious files from running, the policy must be switched from audit mode to enforcement (block) mode.
NEW QUESTION # 74
What does watermarking AI generated content prevent?
Answer: D
Explanation:
Watermarking in AI-generated content helps detect and trace synthetic media, which directly mitigates the risk of deep fakes. By embedding hidden identifiers, organizations can verify whether content was created by AI, reducing misuse for impersonation or disinformation.
NEW QUESTION # 75
A security engineer on an application design team must choose a framework of attack patterns to evaluate during threat modeling. Which framework provides the common set of attacks?
Answer: C
Explanation:
MITRE CAPEC (Common Attack Pattern Enumeration and Classification) provides a standardized catalog of attack patterns. It is specifically designed for use in threat modeling and application design, allowing security engineers to anticipate and evaluate common attacks.
NEW QUESTION # 76
An IT company experienced the spread of malicious content between user endpoints, which impacted business critical resources. The company wants to implement a solution to control communication between individual endpoints on the network. Which approach achieves the goal?
Answer: B
Explanation:
The spread of malicious content between endpoints is a classic case oflateral movement. To control and restrict communication between individual endpoints-regardless of their physical location or IP address- Cisco TrustSecis the recommended architectural approach. TrustSec moves away from traditional, IP-based Access Control Lists (ACLs), which are difficult to manage and scale, and instead usesScalable Group Tags (SGTs).
With TrustSec, every endpoint is assigned an SGT based on its role or security context (e.g., "Employee,"
"Contractor," or "HR"). Security policies are then defined in a centralized matrix (the egress policy matrix) that dictates which SGTs can talk to one another. For example, a policy can be set so that endpoints in the
"Developer" group cannot communicate directly with endpoints in the "Sales" group, effectively preventing malware from hopping between machines. WhileRADIUS(Option A) is the protocol used for authentication, it does not perform the segmentation itself.Posture(Option C) checks the health of the device, andProfiling (Option D) identifies what the device is, but neither provides the policy-based traffic control of TrustSec. By implementing TrustSec, the company achievesmicro-segmentation, significantly reducing the internal attack surface and containing potential breaches within a single group, which is a core goal of modern secure infrastructure design.
