A User Entity Behavior Analysis (UEBA) tool performs active monitoring by continuously analyzing the behavior of users and entities to detect anomalies that may indicate insider threats, compromised accounts, or malicious activity. It uses machine learning and analytics to identify unusual patterns in real time.
Question # 5
An administrator finds multiple gambling websites in the network traffic log.
What can be created to dynamically block these websites?
URL categories classify websites based on content type or risk, enabling dynamic policy enforcement such as blocking or allowing access. Administrators can create custom URL categories to group sites like gambling domains and apply blocking rules across the firewall infrastructure. Palo Alto Networks firewalls leverage URL categorization combined with threat intelligence to provide granular web filtering, reducing exposure to malicious or unwanted sites. This dynamic grouping approach is more manageable and scalable than creating individual signatures or static lists and allows for automated policy application aligned with organizational compliance requirements.
Question # 6
Which statement describes advanced malware?
A.
It operates openly and can be detected by traditional antivirus.
B.
It lacks the ability to exfiltrate data or persist within a system.
Advanced malware employs sophisticated techniques such as polymorphism, encryption, and stealth to evade detection by traditional signature-based tools. It adapts to different environments, modifies its code to avoid static analysis, and maintains persistence through obfuscation and anti-forensic measures. Palo Alto Networks’ threat prevention technologies use machine learning, behavior analysis, and sandboxing to detect these evasive malware strains. Such adaptive capabilities distinguish advanced malware from simpler threats that are easily identified and removed, underscoring the need for modern, layered security controls capable of dynamic threat detection.
Question # 7
Which scenario highlights how a malicious Portable Executable (PE) file is leveraged as an attack?
A.
Setting up a web page for harvesting user credentials
B.
Laterally transferring the file through a network after being granted access
C.
Embedding the file inside a pdf to be downloaded and installed
D.
Corruption of security device memory spaces while file is in transit
Malicious Portable Executable (PE) files hidden inside PDFs represent a stealthy delivery tactic where attackers embed executable payloads within seemingly benign documents. When a user opens the PDF, the embedded PE executes, potentially installing malware. This approach combines social engineering with file obfuscation to bypass traditional detection methods. Palo Alto Networks’ Advanced WildFire sandboxing inspects such files by detonating them in isolated environments to observe behavior and identify hidden threats. This detection technique is critical for uncovering evasive malware concealed within common file types before they reach end-users.
SSL/TLS decryption allows security tools to inspect encrypted traffic, enabling them to detect hidden malware, command-and-control communication, or data exfiltration that would otherwise bypass inspection if left encrypted.
