iOS
iOS: The operating system used by Apple’s iPhone, iPad, and iPod Touch devices. It is used to manage and control the hardware and software components of these devices, as well as provide a platform for third-party applications. Examples of iOS features include the home screen, app store, and Siri voice assistant.
IP address
IP address: An IP address is a numerical identifier assigned to every device connected to an IP network. It serves two primary functions – host or network interface identification and location addressing. IP addresses are essential for routing and delivering packets of data across networks, ensuring that information reaches its correct destination.
IP Authentication Header (AH)
IP Authentication Header (AH): A component of the IPsec suite that provides connectionless data integrity and data origin authentication for IP packets. AH ensures that the contents of the communications have not been altered in transit.
IP Broadcast Methods
IP Broadcast Methods: IP broadcast methods are used to send a message to all potential recipients on a network segment. Types of IP broadcast methods include network broadcast, sending to a subnet’s broadcast address, and limited broadcast, sending to the special address 255.255.255.255, which targets all devices on the local network.
IP Probes
IP Probes: The process of sending small packets of data to a specific IP address to determine if a device is active on a network and to gather information about the device. It is used in network security to identify potential vulnerabilities. Examples include ping and traceroute.
IP Security (IPSec)
IP Security (IPSec): A suite of protocols designed to secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet in a stream of data. IPSec provides a secure channel between two devices and is widely used in VPNs.
