VPN (Virtual Private Network) virtual xususiy tarmoq	VPN (Virtual Private Network) virtual xususiy tarmoq sifatida ta’riflanadi. Bu texnologiya foydalanuvchilar o‘rtasida barcha ma’lumotlarni almashish boshqa tarmoq doirasida ichki tarmoqni shakllantirishga asoslangan, ishonchli himoyani ta’minlashga qaratilgan. VPN uchun tarmoq asosi sifatida Internetdan foydalaniladi
A VPN (Virtual Private Network) is defined as a virtual private network. This technology is aimed at ensuring reliable protection, based on the formation of an internal network, where all data exchange between users is within another network. The Internet is used as the network base for VPN
IDS (Intrusion Detection System) ruxsatsiz kirishlarni aniqlash tizimi.	Ruxsatsiz kirishni aniqlash tizimi (IDS) yordamida tizim yoki tarmoq xavfsizlik siyosatini buzib kirishga harakat qilingan usul yoki vositalar aniqlanadi. Ruxsatsiz kirishlarni aniqlash tizimlari deyarli chorak asrlik tarixga ega. Ruxsatsiz kirishlarni aniqlash tizimlarining ilk modellari va prototiplari kompyuter tizimlarining audit ma’lumotlarini tahlillashdan foydalangan. Bu tizim ikkita asosiy sinfga ajratiladi. Tarmoqqa ruxsatsiz kirishni aniqlash tizimi (Network Intrusion Detection System) va kompyuterga ruxsatsiz kirishni aniqlash tizimiga (Host Intrusion Detection System) bo‘linadi.	An intrusion detection system (IDS) identifies the method or means by which an attempt is made to break into a system or network security policy. Intrusion detection systems have a history of almost a quarter of a century. Early models and prototypes of intrusion detection systems used computer systems audit data analysis. This system is divided into two main classes. It is divided into network intrusion detection system (Network Intrusion Detection System) and computer intrusion detection system (Host Intrusion Detection System).
