😇Aniq bilaman bu narsa haqida siz umuman o'ylab ko'rmagansiz.

Hammamiz ishda domen controller (AD) ishlatamiz. Login parol terib ishlab ketaveramiz. Lekin shu login parol terilgandan keyin nimalar bo'lishini chuqurroq o'ylab ham ko'rmagan bo'lsak kerak.

Keling shu jarayonga sho'ng'iymiz:

🔐 Kerberos: TGT va TGS nimaga kerak?

Aytaylik, siz katta kompaniyada ishlaysiz. Har kuni ofisga kirish, printerdan foydalanish, serverga ulanish kerak. Har safar parol kiritish zerikarli emasmi?
Mana shu muammoni Kerberos yechadi! U sizga faqat *1 marta parol kiritishga* ruxsat beradi, qolgan hamma narsa avtomatik. Qanday qilib? Keling, tushuntiraman!

---

1. TGT (Asosiy пропуск) 🎟
- Nima? TGT — bu sizning "asosiy пропуск"ingiz. Ofisga kirishda qo'riqchi (KDC) sizni tanib oladi va *TGT* beradi.
- Qachon? Kompyuterga birinchi marta kirganingizda.
- Nima qiladi? Ushbu пропуск orqali boshqa xonalarga (servislarga) kirish uchun maxsus ruxsatnomalar olishingiz mumkin.

---

2. TGS (Maxsus ruxsatnoma) 🎫
- Nima? TGS — printer, server yoki boshqa xonalarga kirish uchun kerak bo'ladigan *maxsus ruxsatnoma*.
- Qanday? Agar siz printerdan foydalanmoqchi bo'lsangiz, KDC (qo'riqchi) ga *TGT* ni ko'rsatasiz. U sizga faqat printer uchun *TGS* beradi.
- Afzalligi? Har bir TGS faqat bitta narsa uchun! Agar haker printer ruxsatnomasini o'g'irlasa, serverga kira olmaydi.

Kerberos qanday ishlaydi? 🛠
1. Kirish: Ofisga kirishda TGT olasiz (1-marta parol kiritish).
2. Ruxsat so'rash: Printer kerak? TGT ni ko'rsating → Printer uchun TGS oling.
3. Foydalanish: TGS ni printerga ko'rsating → Sizga ruxsat beriladi!

---

Nega kerak? 💡
- Xavfsizlik: Har bir xona (servis) uchun alohida kalit (TGS).
- Qulaylik: Faqat 1 marta parol kiritish yetarli!
- Tezkorlik: Har safar parol yozish shart emas.

Hayotiy misol 🏢
1. Ofisga kirish: TGT olish = Eshikdan o'tish.
2. Kofe apparatiga kirish: TGT → KDC → "Kofe apparati uchun TGS" olish.
3. Meeting xonasiga kirish: Yana TGT → "Meeting xonasi uchun TGS".

Xulosa: Kerberos — bu sizning ofisdagi aqlli qo'riqchizingiz! U sizga faqat *1 ta asosiy пропуск* beradi, qolgan hamma narsa avtomatik 🚀

📢 Eslatma: Agar TGT yo'qolsa, ofisga qayta kirish kerak (parolni yana kiritish). Shuning uchun uni himoya qiling!

How Does Bitcoin Work?

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”

Should You Buy Bitcoin?

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
