When you enable URL Filtering, all web traffic is compared against the URL Filtering database, PAN-DB, which contains millions of URLs that have been grouped into about 65 categories.

SSL/TLS encrypts and authenticates web-based communication to ensure secure data transmission over networks. It ensures privacy by encrypting the data exchanged between a client and a server, protecting it from interception or tampering. It doesn’t handle user input like passwords directly.

SIEM stands for security information and event management. It is a technology that collects, analyzes, and reports on security-related data from various sources within an organization’s network. The purpose of SIEM is to provide real-time monitoring and analysis of security events, such as user logins, file access, and changes to critical system files. SIEM helps security teams to detect and respond to potential threats, as well as to meet compliance requirements and improve their cybersecurity posture. References: What Is Security Information and Event Management (SIEM)? - Palo Alto Networks, What is a SIEM Solution? - Palo Alto Networks, Integrate IoT Security with SIEM - Palo Alto Networks

2G/2.5G: 2G connectivity remains a prevalent and viable IoT connectivity option due

to the low cost of 2G modules, relatively long battery life, and large installed base of

2G sensors and M2M applications.

○ 3G: IoT devices with 3G modules use either Wideband Code Division Multiple Access

(W-CDMA) or Evolved High Speed Packet Access (HSPA+ and Advanced HSPA+) to

achieve data transfer rates of 384Kbps to 168Mbps.

○ 4G/Long-Term Evolution (LTE): 4G/LTE networks enable real-time IoT use cases, such

as autonomous vehicles, with 4G LTE Advanced Pro delivering speeds in excess of

3Gbps and less than 2 milliseconds of latency.

○ 5G: 5G cellular technology provides significant enhancements compared to 4G/LTE

networks and is backed by ultra-low latency, massive connectivity and scalability for

IoT devices, more efficient use of the licensed spectrum, and network slicing for

application traffic prioritization.
