When we talk about TCP/IP, we are talking about a protocol suite designed as a layered approach and used to interconnect computing devices across the entire continent. Internet Protocol (IP) is like the epitome protocol of the entire TCP/IP protocol suite and helps in the delivery of services. This IP is encapsulated into an IP header before your message is sent. Having briefly discussed about the IP protocol and the encapsulation, here is where typical TCP/IP attacks occur.
Explanation:
- IP address spoofing – As mentioned above, IP is encapsulated into packet headers and inside of those headers are information such as IP source and destination addresses. IP source and destination addresses are needed by the routers to determine the best route path. If hackers can get access to the IP layer, they could easily spoof the source address and somehow make it pretend as if it was another legit host.
- TCP sequence number prediction attack– This is very common. TCT/IP protocol suite contains a three way handshake. For instance, when you do a web search, what is happening is that you are sending information to the server. The server will receive this info and send an acknowledgment receipt with the information it received back to you. You will then send an acknowledgment message to the server and communication will be established. In between this handshake, there is a sequence number called ISN that hackers are able to predict from their own host computers, and this sequence number could send malicious packets to impersonate another source host on a network.
- Port Scanning – It is not a technique used to directly launch an attack. However, hackers can use port scanning to scan a target network for exploitable open ports or listening servers.

You press the TAB to move to the next cell in the row or
press the ENTER to move to the next cell in the column. Whether the entry of
data is in Microsoft Excel or Access, by default, if you wish to move to the
next cell in a row, you are required to hit the tab key and the enter key to
move to the next cell in a column.
In this question, only the "Option c" is correct which can be defined as follows:
- The World Wide Web (WWW) is one way of accessing the information on the web.
- Even if it occupies a significant portion of the web and is the most popular, the two notions should not be viewed as synonyms because they are not the same.
- The WWW is indeed the pages while you're online on a computer device.
- This network of interconnected machines upon, that the web operates, as well as a medium through the emails and data, are being sent and received.
The wrong choices can be defined as follows:
- In option a and Option d, both are wrong because it's the universe of network-accessible data, a manifestation of human understanding.
- In option b, it is wrong because it is a global network of networks, the Internet is also known as WWW.

Answer:
Both of them have only one similarity and that is the intent. Otherwise they are different. Traditional crime required physical labor on majority of occasions, whereas the cyber crime requires always brain and coding only. However, all sites are not information sites. There are various types of sites like eCommerce sites, Content management sites, web applications, mobile friendly sites( for all types of sites) and many more. What you need to do now is certainly to find how the cyber attack is committed. Like by injecting malicious codes through the openings like in WordPress sites we have third party plugins which are always where these malicious codes are injected. How good your authentication is, is also a criteria. You will find at times that all the pages are not covered through authentication like file upload. Malicious files can be uploaded at times when you do not mention what type of files can be uploaded, and thus the hacker can hack your site and put you in vulnerable positions. Now you need to find all these types of situations, and then you can mention how you can opt for a security for each of them. This is a very important issue and all the big companies consider each such risk and their remedies while making a site.
