Answer:
spanning-tree portfast bpduguard
Explanation:
spanning- tree protocol (STP) is a layer 2 protocol in the OSI model. It is automatically configured in a switch to prevent continual looping of BPDUs, to avoid traffic congestion. The fastport bpduguard is only applicable in non-trunking access in a switch. It is more secure to configure the fastport mode in switch port connected directly to a node, because there are still bpdus transfer in a switch to switch connection.
BPDUs Guard ensures that inferior bpdus are blocked, allowing STP to shut an access port in this regard.
Answer:
we need PLC(Programmable Logic Units) attached to the sensors and those sensors will take the signals/values and transfer them to the cloud .In cloud we store that information and send that information to the web application where user is able to view
Explanation:
it looks like a SCADA system. we can integrate PLC with SCADA
or
for developing PLC we can use c or c++.it contain logic to transfer data to cloud
for cloud storage we can use Microsoft azure which is useful for data storage in sql servers
for web application we can use ASP.Net to interact with cloud and get data from there and display the results to the user on UI
The reason nonessential protocols are a security issue that you should be concerned about is that: A. nonessential ports provide additional areas of attack.
<h3>What is information security?</h3>
Information security can be defined as a preventive practice which is typically used to protect an information system (IS) that use, store or transmit information, from potential theft, attack, damage, or unauthorized access, especially through the use of a body of technologies, encryption, frameworks, processes and network engineers.
In Cyber security, the reason nonessential protocols are a security issue that an end user should be concerned about is that nonessential ports would provide additional areas of attack because all protocols have weaknesses based on the principle of least privilege.
