What is IoT?

The Internet of Things (IoT) describes the network of physical objects—“things”—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet.

You will see how IoT important and where does IoT exist in our lives.

Generally, IoT is most abundant in manufacturing, transportation and utility organizations, making use of sensors and other IoT devices; however, it has also found use cases for organizations within the agriculture, infrastructure and home automation industries, leading some organizations toward digital transformation.

How does IoT work and why is important

An IoT system consists of sensors/devices which “talk” to the cloud through some kind of connectivity. Once the data gets to the cloud, software processes it and then might decide to perform an action, such as sending an alert or automatically adjusting the sensors/devices without the need for the user.

Comptia A+ ;you will learn connection standarts like bluetooth, wifi etc.

In this lecture, you will learn IoT security.

IoT security is the practice that keeps your IoT systems safe. IoT security tools protect from threats and breaches, identify and monitor risks and can help fix vulnerabilities. IoT security ensures the availability, integrity, and confidentiality of your IoT solution.

You will learn what are threats and mobile security threats

Information Security threats can be many like Software attacks, theft of intellectual property, identity theft, theft of equipment or information, sabotage, and information extortion.

Ethical hacking involves a hacker agreeing with an organization or individual who authorizes the hacker to levy cyber attacks on a system or network to expose potential vulnerabilities. An ethical hacker is also sometimes referred to as a white hat hacker. Many depend on ethical hackers to identify weaknesses in their networks, endpoints, devices, or applications. The hacker informs their client as to when they will be attacking the system, as well as the scope of the attack. An ethical hacker operates within the confines of their agreement with their client. They cannot work to discover vulnerabilities and then demand payment to fix them. This is what gray hat hackers do. Ethical hackers are also different from black hat hackers, who hack to harm others or benefit themselves without permission.

A reference model—in systems, enterprise, and software engineering—is an abstract framework or domain-specific ontology consisting of an interlinked set of clearly defined concepts produced by an expert or body of experts to encourage clear communication for bug bounty hunting

The IPv4 address is a 32-bit number that uniquely identifies a network interface on a system, as explained in How IP Addresses Apply to Network Interfaces in comptia a.

An Internet Protocol version 4 packet header (IPv4 packet header) contains application information, including usage and source/destination addresses for ethical hackers.

A classful network is a network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing in 1993.

For IPv4, a network may also be characterized by its subnet mask or netmask, which is the bitmask that when applied by a bitwise AND operation to any IP address in the network, yields the routing prefix. Subnet masks are also expressed in dot-decimal notation like an address.

To understand subnetting, you should first understand the decimal and binary structure of an IP address. An IPv4 address is a 32-bit number.

IPv4 address exhaustion is the depletion of the pool of unallocated IPv4 addresses in web hacking .

In IP networking, a private network is a computer network that uses private IP address space.

Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device.

An IPv6 packet is the smallest message entity exchanged using Internet Protocol version 6 (IPv6). Packets consist of control information for addressing and routing and a payload of user data. The control information in IPv6 packets is subdivided into a mandatory fixed header and optional extension headers.

DHCP works at the application layer to dynamically assign the IP address to the client and this happens through the exchange of a series of messages called DHCP transactions or DHCP conversation.

The Internet Control Message Protocol (ICMP) is a supporting protocol in the Internet protocol suite.

Transport layer offers peer-to-peer and end-to-end connection between two processes on remote hosts.CompTIA A+ CompTIA A 220-1001 Exam and A+ Certification

The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite.
Penetration testing skills make you a more marketable IT tech. Understanding how to exploit servers, networks, and applications means that you will also be able to better prevent malicious exploitation. From website and network hacking, to pen testing in Python and Metasploit, Udemy has a course for you.

TCP wraps each data packet with a header containing 10 mandatory fields totaling 20 bytes (or octets). Each header holds information about the connection and the current data being sent. The 10 TCP header fields are as follows: Source port – The sending device's port. Destination port – The receiving device's port.

Comparison of UDP and TCP — In computer networking, the User Datagram Protocol (UDP) is one of the core members of the Internet protocol suite.

Application layer is where the actual communication is initiated and reflects. Because this layer is on the top of the layer stack, it does not serve any other layers. Application layer takes the help of Transport and all layers below it to communicate or transfer its data to the remote host.

DNS, or the domain name system, is the phonebook of the Internet, connecting web browsers with websites.

The Hypertext Transfer Protocol is an application layer protocol for distributed, collaborative, hypermedia information systems.
