Answer:
For shadow passwords the shadow-utils package to be enabled
Explanation:
The shadow-utils package includes the necessary programs forconverting UNIX password files to the shadow password format, plusprograms for managing user and group accounts. The pwconv commandconverts passwords to the shadow password format. The pwunconv commandunconverts shadow passwords and generates a passwd file (a standardUNIX password file). The pwck command checks the integrity of passwordand shadow files. The lastlog command prints out the last login timesfor all users. The useradd, userdel, and usermod commands are used formanaging user accounts. The groupadd, groupdel, and groupmod commandsare used for managing group accounts.
24 bits is an initialization vector (IV) which is used by most weak implementations of the Wireless Equivalency Protocol (WEP).
<h3>What is
Wireless Equivalency Protocol (
WEP)?</h3>
Wireless Equivalency Protocol (WEP) can be defined as a standard wireless protocol that is designed and developed to provide a significant level of security and privacy on 802.11b wireless local area network (WLAN).
According to the IEEE Wireless Fidelity (Wi-Fi) standard, 24 bits is an initialization vector (IV) which is used by most weak implementations of the Wireless Equivalency Protocol (WEP).

yeah i agree with your answer
Answer and Explanation:
DOS attacks refer to Denial of Service attack. It is a sort of digital attack where a programmer hacks the system of a framework and makes it inaccessible for the clients which results in intruding on the internet providers of the machine.
At the end of the day, access to online administrations is denied for the client. Any sort of system administration can be upset by DOS assaults be it either bank site or an online business site.
Following is one of the defense techniques against DOS attacks:
Using Routers and Firewalls - As switches have rate constraining and access control capacities, so they can be set up in a legitimate manner to stop basic ping assaults by permeating unessential conventions and can likewise stop invalid IP addresses. In any case, the main hindrance for utilizing switches is that they are usually ineffective against an increasingly advanced parodied assault and application-level assaults utilizing substantial IP addresses. Presently here comes the job of firewalls. Firewalls can ensure the system by dismissing all the traffic landing from aggressor's end. This insurance by firewalls depends on basic principles dependent on conventions, ports or the starting IP addresses.
Be that as it may, it is difficult to hinder some mind boggling assaults by these straightforward standards. For instance, if there is a progressing assault on port 80 (web administration), it is beyond the realm of imagination to expect to drop all approaching traffic on this port in light of the fact that doing so will keep the server from serving genuine traffic.
One detriment of firewall is that Firewalls can close down a particular stream related with an assault, however like switches, they can't perform hostile to ridiculing.
Your correct answer is A. Always drive at the posted speed limit.
While B. and C. are logically also correct, I wouldn't call them the "golden" rules. Following A. can help you avoid B. to make matters better, hehe.
