QUIZZES WITH COMPLETE SOLUTIONS.
hacker,,ANS,-
,Anyone,who,attempts,to,gain,access,to,unauthorized,resources,on,a,network,,usually,by,finding,a,way,to,
circumvent,passwords,,firewalls,,or,other,protective,measures.
cracker,,ANS,-,Hackers,who,break,into,systems,with,the,intent,of,doing,harm,or,destroying,data.
script,kiddie,,ANS,-
,A,young,,inexperiences,computer,programmer,who,spreads,viruses,and,other,malicious,scripts,and,explo
its,weaknesses,in,computer,systems,using,tools,and,techniques,created,by,others.
packet,monkey,,ANS,-
,A,derogatory,term,for,unskilled,crackers,or,hackers,who,steal,program,code,and,use,it,in,denial,of,service,
attacks,instead,of,creating,the,programs,themselves.
DDoS,(Distributed,Denial,of,Service),,ANS,-
,An,attack,in,which,many,computers,are,hijacked,and,used,to,flood,the,target,with,so,many,false,requests,
that,the,server,cannot,process,them,all,,and,normal,traffic,is,blocked.
hactivist,,ANS,-,Computer,attackers,with,political,goals.

,Malware,designed,to,be,used,at,a,specific,time,in,the,future,or,when,a,specified,condition,exists.
virus,,ANS,-
,Computer,code,that,copies,itself,from,one,place,to,another,surreptitiously,and,performs,actions,that,ran

, back,door,,ANS,-
,Ways,of,gaining,unauthorized,access,to,a,computer,or,other,resource,,such,as,an,unused,port,or,terminal,
service.
port,,ANS,-
,An,area,in,random,access,memory,(RAM),reserved,for,the,use,of,a,program,that,"listens",for,requests,for,
the,service,it,provides.
Trojan,program,,ANS,-
,A,harmful,computer,program,that,appears,to,be,something,useful,to,deceive,a,user,into,installing,it.
macro,,ANS,-,A,type,of,script,that,automates,repetitive,tasks.
SYN,flood,,ANS,-
,When,a,network,is,overloaded,with,packets,that,have,the,SYN,flag,set.,Servers,are,overloaded,with,reque
sts,for,connections,and,are,unable,to,respond,to,legitimate,requests.
social,engineering,,ANS,-
,When,a,person,is,misled,into,giving,out,passwords,or,other,sensitive,information.
malicious,port,scanning,,ANS,-,When,an,attacker,looks,for,open,ports,to,infiltrate,a,network.
ICMP,abuse,,ANS,-,When,a,network,is,flooded,with,a,stream,of,ICMP,echo,requests,to,a,target,computer.
man-in-the-middle,attack,,ANS,-
,When,an,attacker,operates,between,two,computers,in,a,network,and,impersonates,one,computer,to,inte
rcept,communications.
Remote,Procedure,Calls,(RPC),attacks,,ANS,-
,Causes,the,operating,system,to,crash,because,they,are,unable,to,handle,arbitrary,data,sent,to,an,RPC,por
