existsc withinc thec informationc environment,c encompassingc ofc interdependentc networksc ofc
ITc infrastructuresc alongc withc thec residentc data,c includingc thec Internet,c computerc systems,c
telecommunicationsc network,c asc wellc asc thec embeddedc processorsc andc controllersc
(Crowther,c 2017).c
Keyc componentsc andc aspectsc ofc cybersecurityc andc itsc relationc toc thec cyberc domain
Cybersecurityc isc thec safeguardingc ofc thec internet-connectedc systemsc likec thec

thec undertakingc canc bec protectedc fromc anyc unauthorizedc accessc orc maliciousc practice.c
Thec keyc componentsc thatc makec upc cybersecurityc includec applicationc security,c
informationc security,c networkc security,c andc disasterc recoveryc planning,c operationalc
securityc andc end-userc education.c Eachc ofc thesec componentsc workc togetherc andc helpc ac
businessc entityc toc strengthenc itsc ITc posturec andc havec anc edgec againstc cybercriminalsc
andc onlinec hackersc (Whatc arec thec Keyc Elementsc ofc CyberSecurity,c 2020).c Thec keyc
componentsc ofc cybersecurityc playc ac cardinalc rolec forc anc organizationc inc thec vastc cyberc
domainc andc helpc toc managec thec uncertaintyc andc threatsc thatc couldc affectc thec entityc inc

purposec forc choosingc suchc anc approachc isc toc makec thec optimumc usec ofc thec knowledgec
ofc individualsc whoc workc inc thec fieldc ofc informationc system.c Inc thec highlyc unpredictablec
cyberc domainc thec approachc wouldc bec usefulc toc designc ac securec cybersecurityc modelc
thatc isc inc syncc withc thec securityc needsc ofc thec organization.c Thec bottom-upc approachc
couldc bec furtherc adoptedc inc thec broaderc cyberc domainc byc integratingc thec newc insight,c

Botnetsc c Thesec internet-connectedc devicesc couldc bec usedc forc performingc thec
Distributedc Denial-of-Servicec (DDOS)c attacks,c stealc datac andc givec unauthorizedc
accessc toc thec attackerc (Eslahic etc al.,c 2012).c
Ransomwarec c Thisc threatc couldc gainc unauthorizedc accessc toc thec ITc systemc ofc
