Applications and defenses for network security$($s$)$ DomainWhat the CIA Does

Intrusion detection system $($IDS$)$ or intrusion protection system $($IPS$)$LAN$-$to$-$WAN ZoneFinds and stops unauthorized access $($integrity$),$ keeps an eye out for fishy activities $($confidentiality$),$ and makes sure the network is always available by stopping malicious traffic $($availability$).$

Keys for LAN Domain, LAN$-$to$-$WAN Domain, and WAN DomainOffers privacy through encryption, trustworthiness through digital signatures, and accessibility by making sure contact channels are safe.

Sign$-$in rightsDomains for Users, System, and ApplicationsControls access to sensitive information and resources to protect user accounts and rights and ensures privacy and integrity.

Front LineLAN$-$to$-$WAN ZoneIt manages the traffic going between networks and makes sure that security rules are followed to protect privacy $($by stopping unwanted access$),$ integrity $($by stopping unauthorized changes$),$ and availability $($by blocking malicious traffic$).$

The LAN$-$to$-$WAN domain and the proxy LAN domainHelps protect privacy, integrity, and availability by putting clients and servers in touch with each other and hiding clients' IP addresses. Content is filtered and cached to guarantee these things.

Antivirus software for the system or application domainFinds and gets rid of malware to protect privacy $($by stopping data breaches$),$ integrity $($by stopping changes made without permission$),$ and availability $($by keeping systems from going down because of malware outbreaks$).$

Private network on the internetRemote Access Domain protects sensitive information $($by encrypting traffic$),$ data integrity $($by stopping tampering$),$ and network availability $($by setting up reliable links$)$ when working from outside the company.

LAN Domain MAC address filtering controls access to network resources based on MAC addresses, improving security $($by limiting access to approved devices$),$ availability $($by stopping unauthorized devices from connecting$),$ and privacy $($by limiting access to authorized devices$).$
