NEW QUESTION # 148
Which is a correct description of a stage in the Lockheed Martin kill chain?

A. In the delivery stage, malware collects valuable data and delivers or exfilltrated it to the hacker.
B. In the weaponization stage, which occurs after malware has been delivered to a system, the malware executes Its function.
C. In the reconnaissance stage, the hacker assesses the impact of the attack and how much information was exfilltrated.
D. In the exploitation and installation phases, malware creates a backdoor into the infected system for the hacker.

Answer: D

Explanation:
The Lockheed Martin Cyber Kill Chain model describes the stages of a cyber attack. In the exploitation phase, the attacker uses vulnerabilities to gain access to the system. Following this, in the installation phase, the attacker installs a backdoor or other malicious software to ensure persistent access to the compromised system. This backdoor can then be used to control the system, steal data, or execute additional attacks.

NEW QUESTION # 149
What is social engineering?

A. Hackers use Artificial Intelligence (Al) to mimic a user's online behavior so they can infiltrate a network and launch an attack.
B. Hackers intercept traffic between two users, eavesdrop on their messages, and pretend to be one or both users.
C. Hackers spoof the source IP address in their communications so they appear to be a legitimate user.
D. Hackers use employees to circumvent network security and gather the information they need to launch an attack.

Answer: D

Explanation:
Social engineering in the context of network security refers to the techniques used by hackers to manipulate individuals into breaking normal security procedures and best practices to gain unauthorized access to systems, networks, or physical locations, or for financial gain. Hackers use various forms of deception to trick employees into handing over confidential or personal information that can be used for fraudulent purposes. This definition encompasses phishing attacks, pretexting, baiting, and other manipulative techniques designed to exploit human psychology. Unlike other hacking methods that rely on technical means, social engineering targets the human element of security. to social engineering, its methods, and defense strategies are commonly found in security training manuals, cybersecurity awareness programs, and authoritative resources like those from the SANS Institute or cybersecurity agencies.

NEW QUESTION # 150
A company with 382 employees wants to deploy an open WLAN for guests. The company wants the experience to be as follows:

The company also wants to provide encryption for the network for devices mat are capable, you implement Tor the WLAN?
Which security options should

A. Captive portal and Opportunistic Wireless Encryption (OWE) in transition mode
B. Opportunistic Wireless Encryption (OWE) and WPA3-Personal
C. Captive portal and WPA3-Personai
D. WPA3-Personal and MAC-Auth

Answer: A

Explanation:
For a company that wants to deploy an open WLAN for guests with the ease of access and encryption for capable devices, using a captive portal with Opportunistic Wireless Encryption (OWE) in transition mode would be suitable. The captive portal allows for a user-friendly login page for authentication without a pre-shared key, and OWE provides encryption to protect user data without the complexities of traditional WPA or WPA2 encryption, which is ideal for guest networks. Transition mode allows devices that support OWE to use it while still allowing older or unsupported devices to connect.References:

NEW QUESTION # 151
Refer to the exhibit.
A company has an HPE Aruba Networking Instant AP cluster. A Windows 10 client is attempting to connect to a WLAN that enforces WPA3-Enterprise with authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM). CPPM is configured to require EAP-TLS. The client authentication fails. In the record for this client's authentication attempt on CPPM, you see this alert.
What is one thing that you check to resolve this issue?

A. Whether the client has a valid certificate installed on it to let it support EAP-TLS
B. Whether the client has a third-party 802.1X supplicant, as Windows 10 does not support EAP-TLS
C. Whether EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster
D. Whether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster

Answer: A

Explanation:
The scenario involves an HPE Aruba Networking Instant AP (IAP) cluster with a WLAN configured for WPA3-Enterprise security, using HPE Aruba Networking ClearPass Policy Manager (CPPM) as the authentication server. CPPM is set to require EAP-TLS for authentication. A Windows 10 client attempts to connect but fails, and the CPPM Access Tracker shows an error: "Client does not support configured EAP methods," with the error code 9015 under the RADIUS protocol category.
EAP-TLS (Extensible Authentication Protocol - Transport Layer Security) is a certificate-based authentication method that requires both the client (supplicant) and the server (CPPM) to present valid certificates during the authentication process. The error message indicates that the client does not support the EAP method configured on CPPM (EAP-TLS), meaning the client is either not configured to use EAP-TLS or lacks the necessary components to perform EAP-TLS authentication.
Option B, "Whether the client has a valid certificate installed on it to let it support EAP-TLS," is correct. EAP-TLS requires the client to have a valid client certificate issued by a trusted Certificate Authority (CA) that CPPM trusts. If the Windows 10 client does not have a client certificate installed, or if the certificate is invalid (e.g., expired, not trusted by CPPM, or missing), the client cannot negotiate EAP-TLS, resulting in the error seen in CPPM. This is a common issue in EAP-TLS deployments, and checking the client's certificate is a critical troubleshooting step.
Option A, "Whether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster," is incorrect because the error indicates that CPPM received the authentication request and rejected it due to the client's inability to support EAP-TLS. This suggests that the IAP cluster is correctly configured to use EAP-TLS (as the request reached CPPM with EAP-TLS as the method). The AAA profile on the IAP cluster is likely already set to use EAP-TLS, or the error would be different (e.g., a connectivity or configuration mismatch issue).
Option C, "Whether EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster," is incorrect for a similar reason. The SSID profile on the IAP cluster defines the security settings (e.g., WPA3-Enterprise), and the AAA profile specifies the EAP method. Since the authentication request reached CPPM with EAP-TLS, the IAP cluster is correctly configured to use EAP-TLS.
Option D, "Whether the client has a third-party 802.1X supplicant, as Windows 10 does not support EAP-TLS," is incorrect because Windows 10 natively supports EAP-TLS. The built-in Windows 10 802.1X supplicant (Windows WLAN AutoConfig service) supports EAP-TLS, provided a valid client certificate is installed. A third-party supplicant is not required.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"EAP-TLS requires both the client and the server to present a valid certificate during the authentication process. If the client does not have a valid certificate installed, or if the certificate is not trusted by ClearPass (e.g., the issuing CA is not in the ClearPass trust list), the authentication will fail with an error such as 'Client does not support configured EAP methods' (Error Code 9015). To resolve this, ensure that the client has a valid certificate installed and that the certificate's issuing CA is trusted by ClearPass." (Page 295, EAP-TLS Troubleshooting Section) Additionally, the HPE Aruba Networking Instant 8.11 User Guide notes:
"For WPA3-Enterprise with EAP-TLS, the client must have a valid client certificate installed to authenticate successfully. If the client lacks a certificate or the certificate is invalid, the authentication will fail, and ClearPass will log an error indicating that the client does not support the configured EAP method."

NEW QUESTION # 152
Which is an accurate description of a type of malware?

A. Malvertising can only infect a system if the user encounters the malware on an untrustworthy site.
B. Rootkits can help hackers gain elevated access to a system and often actively conceal themselves from detection.
C. Worms are usually delivered in spear-phishing attacks and require users to open and run a file.
D. A Trojan is any type of malware that replicates itself and spreads to other systems automatically.

Answer: B

Explanation:
Malware (malicious software) is a broad category of software designed to harm or exploit systems. HPE Aruba Networking documentation often discusses malware in the context of network security threats and mitigation strategies, such as those detected by the Wireless Intrusion Prevention (WIP) system.
Option A, "Worms are usually delivered in spear-phishing attacks and require users to open and run a file," is incorrect. Worms are a type of malware that replicate and spread automatically across networks without user interaction (e.g., by exploiting vulnerabilities). They are not typically delivered via spear-phishing, which is more associated with Trojans or ransomware. Worms do not require users to open and run a file; that behavior is characteristic of Trojans.
Option B, "Rootkits can help hackers gain elevated access to a system and often actively conceal themselves from detection," is correct. A rootkit is a type of malware that provides hackers with privileged (elevated) access to a system, often by modifying the operating system or kernel. Rootkits are designed to hide their presence (e.g., by concealing processes, files, or network connections) to evade detection by antivirus software or system administrators, making them a stealthy and dangerous type of malware.
Option C, "A Trojan is any type of malware that replicates itself and spreads to other systems automatically," is incorrect. A Trojan is a type of malware that disguises itself as legitimate software to trick users into installing it. Unlike worms, Trojans do not replicate or spread automatically; they require user interaction (e.g., downloading and running a file) to infect a system.
Option D, "Malvertising can only infect a system if the user encounters the malware on an untrustworthy site," is incorrect. Malvertising (malicious advertising) involves embedding malware in online ads, which can appear on both trustworthy and untrustworthy sites. For example, a legitimate website might unknowingly serve a malicious ad that exploits a browser vulnerability to infect the user's system, even without the user clicking the ad.
The HPE Aruba Networking Security Guide states:
"Rootkits are a type of malware that can help hackers gain elevated access to a system by modifying the operating system or kernel. They often actively conceal themselves from detection by hiding processes, files, or network connections, making them difficult to detect and remove. Rootkits are commonly used to maintain persistent access to a compromised system." (Page 22, Malware Types Section) Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:
"The Wireless Intrusion Prevention (WIP) system can detect various types of malware. Rootkits, for example, are designed to provide hackers with elevated access and often conceal themselves to evade detection, allowing the hacker to maintain control over the infected system for extended periods."
