An active attack is a network exploit in which a hacker attempts to make
changes to data on the target or data en route to the target. They are quite
difficult to prevent active attacks absolutely because of the wide
variety of potential physical, software, and network vulnerabilities.
Briefly discuss three such attacks.

Expert Solution

Here i am going discuss mainly about three active attacks:

Masquerade Attack
Message Modification Attack
Denial of service

1.Masquerade Attack:

This is a type of attack in which an unauthorised person sends a message to the receiver in the same of sender.
Actually here the sender didnt send any message to the receiver but the receiver going to receive message in name of sender.
This attack is mainly done to theft the confidential data from the receiver.

2. Message Modification:

In this attack when a sender tries to send a message to the receiver, the third party person gets the access to that message.
It means that the message sent by the sender was actually received by the unauthorised person.
Then the unauthorised person modifies the message and send it to receiver in the name of sender.

3.Denial of service:

In this attack the unauthorised person makes the server flooded with traffic so that the user wont get any services from the server.
This creates a lot of headache for the user to use the services of server.

Ryan is a hacker who plans to exploit victims by uploading a malicious webpage in the cloud. He uses a vulnerability to exploit the cloud presence of XYZ Coffee, a legitimate company. From there, he installs a malware that inserts a malicious payload into web pages displayed, social media, and hides his malicious activity from the anti-virus. He then redirects victims to the website, which infects them with malware. In addition, the hacker used anti forensics tools. Users complain to...

3a. The catalytic mechanism of an enzyme involves nucleophilic attack on the substrate by an active site cysteine. Normally, this cysteine has a pKa of 8.2. If the cytoplasm of the cell is pH 7.2 and the pH of the mitochondrial matrix is 8.2, predict whether this enzyme is a better catalyst in the cytoplasm or mitochondria. Explain

1.When the substrates bind to the active of an enzyme, the active site changes shape. This is an example of: a) lock & key model; b) inhibitor model; c) allosteric model; d) induced fit model; e) none. 2. The change in free energy at equilibrium is: a) increased; b) decreased; c) no net change 3. You have a gram of each of the following: bacon grease, lean ground turkey and bread. Which on has more potential energy and why? a)...

Write a C++ program that attempts to make the Radix Sort more practical: make it sort strings of a maximum length of 15. Have an array of strings. Then in the Radix Sort, create an array of LinkedQueue with 95 queues (95 are the printable characters starting with space). Those queues will be used to separate the data then combine them (i.e. bins). Randomly generate 10,000 strings with lengths from 1 to 15 (during the sort and with strings less...
