which of the flowing is not a correct statement regarding firewalls

Ahmed should anticipate potential security issues.

If Ahmed notices three events related to a remote access attempt being highlighted with a yellow exclamation mark in the Windows Server 2019 system log, he should anticipate potential security issues.

These events could indicate that someone is attempting to gain unauthorized access to the server, potentially to steal or manipulate data, or to disrupt the system.

Ahmed should investigate the source of these events and take appropriate action to secure the server and prevent further unauthorized access attempts. This could involve implementing additional security measures, such as firewalls or password protection, or disabling remote access altogether.

Ahmed should also keep an eye on the system log for any additional warning signs and take action to address them promptly.

def measure_amortized_cost_of_appending(num_iterations):

 # Create an empty list

 lst = []

 # Start a timer

 start_time = time.perf_counter()

 # Append num_iterations elements to the list

 for i in range(num_iterations):

   lst.append(i)

 # End the timer

 end_time = time.perf_counter()

 # Calculate and return the amortized cost of appending

 return (end_time - start_time) / num_iterations

This function creates an empty list, starts a timer, appends num_iterations elements to the list, and ends the timer. It then calculates and returns the amortized cost of appending by dividing the elapsed time by the number of iterations.

An intruder transmitting packets from the outside with a source ip address field containing an address of an internal host is known as ip address SPOOFING.

IP address spoofing is a malicious practice that puts computer networks and users at risk. It occurs when an intruder transmits packets from the outside with a source IP address field containing an address of an internal host. This technique is used to gain unauthorized access to a network, hide the true identity of the sender, and even launch a denial-of-service attack. As a result, it is important to understand what IP address spoofing is, how it works, and the security measures that can be taken to protect oneself from it.

First, it is important to understand what IP spoofing is and how it works. IP spoofing is essentially a type of network attack where the attacker modifies the source address of an IP packet to make it appear as though the packet originated from a different source. This is done by changing the origin of the packet to the internal address of another user on the network, allowing the attacker to gain access to the network and perform malicious activities. The intruder can then use this access to steal information, launch a denial of service attack, or even gain control of the network.
