HP HPE6-A78 Exam With Confidence Using Practice Dumps

An ArubaOS user role determines the firewall policies and bandwidth contracts that apply to the client’s traffic. When a user is authenticated, they are assigned a role, and this role has associated policies that govern network access rights, Quality of Service (QoS), Layer 2 forwarding, Layer 3 routing behaviors, and bandwidth contracts for users or devices.

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." (Page 421, Malware Threats Section)

WPA3-Enterprise enhances network security over WPA2-Enterprise through several improvements, one of which is the ability to operate in CNSA (Commercial National Security Algorithm) mode. This mode mandates the use of secure cryptographic algorithms during the 802.11 association process, ensuring that all communications are highly secure. The CNSA suite provides stronger encryption standards designed to protect sensitive government, military, and industrial communications. Unlike WPA2, WPA3's CNSA mode uses stronger cryptographic primitives, such as AES-256 in Galois/Counter Mode (GCM) for encryption and SHA-384 for hashing, which are not standard in WPA2-Enterprise.
