I agree. No one wants to click on a website only to be burdened with the task of removing malware form their computer. Therefore, harmful pages should get a low quality rating.
Answer:
It was not a good choice and the administrator could have gone with a much better option.
Explanation:
Choosing WPA over WEP is a good option. It is however, still considered vulnerable despite its improved security and has been superseded by the WPA2 security protocol. TKIP is an example of an encryption method that was introduced around the same time with WPA and replaced WEP. This encryption is not secure and is now out of date and I would highly recommend against its use. If the access points support WPA2 – AES, then this would be the best and is the most optimal for wireless security.
The complete question rather reads;
DRU is a small brokerage house that enables its clients to buy and sell
stocks over the Internet, as well as place traditional orders by phone or Fax. DRU has just decided to install a new e-mail package. One vendor offering an SMTP-based two-tier client-server architecture. The second vendor is offering a Web-based e-mail architecture. DRU doesn't understand either one but thanks the Web-based one should be better because, in their words, "the Web is the future".
<u>(a) Briefly explain to DRU management, in layperson's terms, the difference between the two.</u>
<u>(b) Outline the pros and cons of the two alternatives and </u>
<u>(c) Recommend to DRU about which is better</u>
<u>Explanation:</u>
a) SMTP stands for Simple Mail Transfer Protocol. Thus, put simply an SMTP-based two-tier client-server architecture is a package that involves using a client-server provider like Outlook. This implies that Outlook provides the client with his own unique PO Box (server) so to speak.
While the Web-based e-mail architecture enables the DRU access to online mail platforms like G-mail with little server customisation features.
b. The Web-based e-mail architecture is good for personal email activities because of its ease of operation, however, it does not provide top security and customisation features. While an SMTP-based two-tier client-server architecture allows for unique server customisation with added security features as well be suitable for larger organisational work. Although a disadvantage is that it may cost more and quite a complex process to learn.
c) Since DRU is a growing firm the SMTP-based two-tier client-server architecture would be recommended as this would provide it will efficient customer service delivery.
