Why hub is not secure?
Summary of the article:
Here are some key points about hubs and switches:
1. What is the main disadvantage of a hub?
A hub lacks collision detection, does not operate in full-duplex mode, cannot be divided into segments, cannot reduce network traffic, and cannot filter information.
2. Why is a switch more secure than a hub?
Switches operate in the application layer of the OSI model and transmit data only to specific network devices, rather than broadcasting it to all devices in a network. They do not require port mirroring for network monitoring.
3. Why don’t we use hubs anymore?
Hubs do not support simultaneous transmission and receiving, which can result in collisions when multiple workstations send messages at the same time.
4. Does a hub create security concerns?
Yes, hubs have speed losses, lack flexibility in data transfer, lack selected recipient options, and are vulnerable to security issues as data traffic does not occur in a protected manner.
5. Why would someone use a hub?
Hubs are commonly used to connect segments of a LAN (Local Area Network) and act as a common connection point for devices.
6. Why is the hub becoming obsolete in modern networks?
Network hubs lack routing capabilities and broadcast all information to multiple ports, leading to performance and security issues. They have been replaced by network switches.
7. What are the disadvantages of using a hub over a switch?
Hubs cannot differentiate between devices on a network, requiring every computer to receive messages, which consumes bandwidth.
8. Why are hubs more vulnerable in terms of security?
Centralized hubs are visible in a network, making them susceptible to compromise by other nodes in the network.
9. What is a major issue with hubs?
Hubs have limited bandwidth, resulting in slower network speeds and increased congestion. They cannot differentiate between different types of network traffic, leading to security vulnerabilities.
10. When did people stop using hubs?
Hubs have been largely replaced by network switches since 2011, except in very old installations or specialized applications.
11. Which is better, a switch or a hub?
Switches are more efficient than hubs as they offer improved security, performance, and flexibility.
What is the main disadvantage of hub
Disadvantages of Hub
It does not include mechanisms such as collision detection. It does not operate in full-duplex mode and cannot be divided into the Segment. It cannot reduce the network traffic as it has no mechanism. It is not able to filter the information as it transmits packets to all the connected segments.
Why is a switch more secure than a hub
Why are switches more secure than hubs Switches operate in the application layer of the OSI model. Switches don't require port mirroring for a network analyst to monitor traffic. Switches will transmit data only to specific network devices, rather than broadcasting the same data to all of the devices in a network.
Why don t we use hubs anymore
There is no simultaneous transmission and receiving while using a hub. If, for example, two workstations connected to the same hub sent a message out at the same time, there would be a collision.

Does a hub create security concerns
In addition to the speed losses mentioned above, and the lack of flexibility in terms of data transfer and the selected recipients, a hub system is also comparatively vulnerable to security issues. For example, the system cannot be quarantined and data traffic does not take place in a protected manner.
Why would someone use a hub
Hub is commonly used to connect segments of a LAN (Local Area Network). A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. Hub acts as a common connection point for devices in a network.
Why is the hub becoming obsolete in modern networks
Unlike switches or routers, network hubs have no routing capabilities and simply broadcast all information to multiple ports. Because of how the network hubs function, they present serious performance and security issues. As a result, hubs are now largely obsolete, having been replaced by network switches.
What are the disadvantages of using a hub over a switch
Hubs are at a disadvantage against switches in networking because hubs are unable to differentiate between the devices on the network. If one computer is trying to reach another on a hub-based network, the computer will send the message to every other computer on the network, consuming bandwidth for each transfer.
Why hubs are more vulnerable in the context of security
However, centralised hubs tend to be visible in a network and this makes them vulnerable. Communication always leads back to them and most other nodes in the network are in a position to compromise them.
What is a major issue with hubs
However, hubs have several significant disadvantages, including their limited bandwidth, which can result in slower network speeds and increased congestion. They cannot also differentiate between different types of network traffic, which can lead to security vulnerabilities.
When did people stop using hubs
Hubs are now largely obsolete, having been replaced by network switches except in very old installations or specialized applications. As of 2011, connecting network segments by repeaters or hubs is deprecated by IEEE 802.3.
Which is better a switch or a hub
Switches are more efficient than hubs, as they are better suited for connecting individual devices rather than connecting networks. It is designed to be an address-based connection, as they use the source and destination address for data transmission.
Does a hub send data to all devices
When a hub receives a data packet (an Ethernet frame) from a network device at one of its ports, it broadcasts (repeats) the packet to all of its ports,i.e, to all other network devices.
Does a hub send data to everyone
Unlike other network devices, a hub does not offer the option to control or exclude only individual receivers. This means that all data packets are always forwarded to all computers during a transfer. This means that even those devices the data wasn't intended for also receive the data.
What are the pros and cons of a hub
Advantages and disadvantages of hubEasy to install.Very little delay.It is used for internal connectivity between the system.Can different media type.Cheaper.Hub device does not affect the performance of the network seriously.It can extend the total distance of the network.
Why are hubs bad networking
Network hubs are best suited for small, simple local area network (LAN) environments. Hubs cannot provide routing capabilities or other advanced network services. Because they operate by forwarding packets across all ports indiscriminately, network hubs are sometimes referred to as "dumb switches."
What is a major problem with a hub vs a switch
Hubs do not provide packet filtering. Switches provide packet filtering. Hub uses half duplex transmission mode. Switch uses full duplex transmission mode.
When would you prefer switch over a hub
A switch is preferred over a hub because a switch will only send message to device that needs or request it.

Which is better hub or switch
Switches are more efficient than hubs, as they are better suited for connecting individual devices rather than connecting networks. It is designed to be an address-based connection, as they use the source and destination address for data transmission.
Where does hub send data
When a hub receives a data packet (an Ethernet frame) from a network device at one of its ports, it broadcasts (repeats) the packet to all of its ports,i.e, to all other network devices. A collision occurs when two network devices on the same network try to send packets at the same time.
What replaced hubs
A switch is effectively a higher-performance alternative to a hub.
Why use a hub over a switch
A hub can connect two or more devices on LAN via Ethernet. However, a switch can join multiple devices in one LAN. The hub uses a half-duplex mode to exchange the data. A switch uses a half/full-duplex mode.
Why are hubs undesirable
However, hubs have several significant disadvantages, including their limited bandwidth, which can result in slower network speeds and increased congestion. They cannot also differentiate between different types of network traffic, which can lead to security vulnerabilities.
What do hubs do with information they receive
Each computer enters the hub with a cable, and data sent from one computer to another passes through the hub. Additionally, a hub can't pinpoint the source or destination of the data it receives. So, it sends the information to all connected computers, including the one that sent it.
