Answer:
Explanation:
There are many weaknesses/vulnerabilities, some of which are the following...
Default Network Hardware, many individuals will go out and buy a new router and install it in their home. These devices come with a preset configuration including a preset security password which is many times a default password used for every router of the same model. This can be easily obtained by anyone who can then access the network.
Access Point hacking, an experienced individual can use a packet sniffer to detect the SSID that is frequently sent from the router in order to create an access point to be able to access the network.
WEP encryption is another vulnerability. These are very low security passwords that can be cracked using different software in a short period of time.
These are some of many vulnerabilities that wireless local networks have, but there are also many precautions and security measures that can be taken to prevent them.
Answer:
We can periodically take a snapshot of the Domain Name System (DNS) caches in the local Domain Name System (DNS) servers.
Explanation:
We can periodically take a snapshot of the Domain Name System (DNS) caches in the local Domain Name System (DNS) servers. The Web server that appears most frequently in the Domain Name System (DNS) caches is the most popular server. This is because if more users are interested in a Web server, then Domain Name System (DNS) requests for that server are more frequently sent by users. Thus, that Web server will appear in the Domain Name System (DNS) caches more frequently.
Answer: rootkit
Explanation:
Hi, A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed (for example, to an unauthorized user) and often masks its existence or the existence of other software.
A rootkit provides continued privileged access to a computer while hiding its presence. Because of this hiding characteristic it is very difficult to detect.
Once a rootkit has been installed, it allows someone to have total remote control of a computer and do things such as files executions and system changes.
Answer:
year = int(input("Enter a year: "))
if (year % 4) == 0:
if (year % 100) == 0:
if (year % 400) == 0:
print(str(year) + " - leap year")
else:
print(str(year) +" - not a leap year")
else:
print(str(year) + " - leap year")
else:
print(str(year) + "- not a leap year")
Explanation:
*The code is in Python.
Ask the user to enter a year
Check if the <u>year mod 4</u> is 0 or not. If it is not 0, then the year is not a leap year. If it is 0 and if the <u>year mod 100</u> is not 0, then the year is a leap year. If the <u>year mod 100</u> is 0, also check if the <u>year mod 400</u> is 0 or not. If it is 0, then the year is a leap year. Otherwise, the year is not a leap year.
