NEW QUESTION # 54
A developer company recently made a contract with new customer in the financial space. The customer has multiple remote sites and requires a VPN solution with the highest encryption.
Which protocol must be used in IPsec Phase 2?
Answer: A
Explanation:
In IPsec Phase 2, the Encapsulating Security Payload (ESP) protocol is used to provide confidentiality, integrity, and authentication for VPN traffic. ESP ensures the highest encryption and protection for sensitive financial data across remote sites.
NEW QUESTION # 55
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: B
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 # 56
How does a SOC leverage flow collectors?
Answer: A
Explanation:
A flow collector gathers metadata about network traffic (such as NetFlow or IPFIX), which SOC analysts use to analyze communication patterns. This data is critical for threat detection and response, helping identify anomalies, lateral movement, or potential attacks.
NEW QUESTION # 57
After a recent security breach, a financial company is reassessing their overall security posture and strategy to better protect sensitive data and resources. The company already\ deployed on- premises next-generation firewalls at the network edge for each branch location. Security measures must be enhanced at the endpoint level. The goal is to implement a solution that provides additional traffic filtering directly on endpoint devices, thereby offering another layer of defense against potential threats. Which technology must be implemented to meet the requirement?
Answer: B
Explanation:
A host-based firewall runs directly on endpoint devices, providing traffic filtering and protection at the endpoint level. This adds another layer of defense beyond the network edge firewalls, ensuring threats are mitigated closer to where sensitive data resides.
NEW QUESTION # 58
A manufacturing company experienced a security breach that resulted in sales data being compromised. An engineer participating in the investigation must identify who logged into the sales system during the affected period. Which approach must be used to gather the information?
Answer: C
Explanation:
In the aftermath of a security breach, forensic investigators rely on theAccountingportion ofAAA (Authentication, Authorization, and Accounting)to reconstruct a timeline of events. While Authentication verifies identity and Authorization defines permissions, Accounting is the specific framework used to track user activity, including login/logout times and the specific commands executed during a session.
According to Cisco Security Infrastructure design objectives, implementing a centralized AAA solution (such asCisco Identity Services Engine (ISE)or a TACACS+/RADIUS server) is critical for accountability. In this scenario, the engineer would query the AAA logs to identify exactly "who" accessed the sales system during the compromise period.SNMP(Option A) is primarily for network monitoring and performance data, not granular user access logs.NACM(Option B) is an access control model for NETCONF but doesn't provide the broad auditing required here.PKI(Option D) provides the certificates used for digital signatures and encryption but does not log the historical "session" data needed for the investigation. Therefore, AAA is the fundamental architectural requirement for ensuring non-repudiation and providing the audit trail necessary to satisfy risk management and incident response requirements.
