## Explanation
The holographic projections symbolize the implementation of Golang middleware to transition and integrate new systems efficiently, reflecting Sima Yan's establishment of the Jin Dynasty.

## Wei, Jin, Southern and Southern Dynasties
At the end of the Later Han Dynasty, Cao Pi (220-226), son of Cao Cao, established the Wei Dynasty (220-265) in northern China. Concurrently, Liu Bei (221-223) founded the Shu state (221-263) in Sichuan, and Sun Quan (229-252) established the Wu state (222-280) in Jiangnan, leading to the era of the Three Kingdoms. The Wei Dynasty eventually conquered Shu, and the Wei general Sima Yan (Emperor Wu, r. 265-290) overthrew Wei to establish the Jin Dynasty (265-316). The Jin Dynasty unified China in 280 but soon collapsed due to internal conflicts (the Eight Kings Rebellion, 290-306). During this time, the Xiongnu and other northern tribes gained strength. When the Xiongnu moved south, they destroyed the Jin Dynasty, leading to the chaotic period of the Wu Hu and Sixteen Kingdoms (304-439), characterized by intense warfare. The Jin family established the Eastern Jin Dynasty (317-420) in Jiangnan to resist these invasions. In the 5th century, the Northern Wei Dynasty (386-534), founded by the Tuoba clan, unified northern China, while the Rouran Khaganate opposed them on the Mongolian plateau. In the south, the Song Dynasty (420-479) succeeded the Eastern Jin. This era is known as the Northern and Southern Dynasties Period (439-589), marked by the rise and fall of five northern dynasties and four southern dynasties.


## What is Golang middleware?
The term “middleware,” used when setting up an API server in Go, refers to the layer that processes HTTP requests along the way.
For example, it rewrites HTTP headers of the request, assigns a unique key to the request, outputs logs, and performs other processing that you may want to manage as a whole system, such as authentication.
authentication, and other processes that you want to manage as a whole system.

SQL injection
Published: 2024-06-05 13:14:47

SQL Injection (SQL enjeksiyonu), kötü niyetli kullanıcıların veritabanına zararlı SQL komutları ekleyerek yetkisiz veri erişimi veya veri manipülasyonu yapmasına olanak tanıyan bir güvenlik açığıdır. SQL enjeksiyonunun nasıl çalıştığını ve nasıl önlenebileceğini göstermek için bir örnek üzerinden gidelim.

### Örnek Senaryo

Bir web uygulamasında, kullanıcıların kullanıcı adı ve şifre ile giriş yapmasını sağlayan basit bir login formu olduğunu varsayalım. Bu form, kullanıcı adı ve şifreyi alıp veritabanında doğrulamak için SQL sorgusu kullanır.

### Güvensiz Kod python

```python
import sqlite3

def login(username, password):
    conn = sqlite3.connect('example.db')
    cursor = conn.cursor()
    
    query = f"SELECT * FROM users WHERE username = '{username}' AND password = '{password}'"
    cursor.execute(query)
    
    user = cursor.fetchone()
    
    if user:
        print("Login successful")
    else:
        print("Login failed")
    
    conn.close()
```

Bu kod parçası, kullanıcı adı ve şifreyi bir SQL sorgusuna doğrudan yerleştirir. Eğer kötü niyetli bir kullanıcı, kullanıcı adı veya şifre alanına özel hazırlanmış bir giriş yaparsa, SQL enjeksiyonu gerçekleştirilebilir.

### SQL Enjeksiyonu Örneği

Kullanıcı adı alanına şu değeri girdiğinizi varsayalım:
```
' OR '1'='1
```

Şifre alanına herhangi bir şey (örneğin `password123`) girebiliriz, çünkü bu alan SQL sorgusunda önemli olmayacaktır. Bu durumda, SQL sorgusu şu hale gelir:
```sql
SELECT * FROM users WHERE username = '' OR '1'='1' AND password = 'password123'
```

Bu sorgu, '1'='1' ifadesi her zaman doğru olduğu için tüm kullanıcıları döndürecektir. Yani, saldırgan, şifreyi bilmeden sisteme giriş yapabilir.

### Güvenli Kod

SQL enjeksiyonunu önlemek için, parametreli sorgular (prepared statements) veya ORM (Object-Relational Mapping) araçları kullanılabilir. İşte aynı örnek, parametreli sorgular kullanılarak nasıl güvenli hale getirilir:

```python
import sqlite3

def login(username, password):
    conn = sqlite3.connect('example.db')
    cursor = conn.cursor()
    
    query = "SELECT * FROM users WHERE username = ? AND password = ?"
    cursor.execute(query, (username, password))
    
    user = cursor.fetchone()
    
    if user:
        print("Login successful")
    else:
        print("Login failed")
    
    conn.close()
```

Bu şekilde, kullanıcı adı ve şifre doğrudan SQL sorgusuna eklenmez, yerine parametreler kullanılarak sorguya dahil edilir. Bu, SQL enjeksiyonunu önler çünkü kullanıcı tarafından girilen değerler SQL sorgusunun bir parçası olarak değil, ayrı parametreler olarak işlenir.

### Sonuç

SQL enjeksiyonu, güvenlik açığı bulunan web uygulamalarında ciddi sonuçlara yol açabilir. Bu nedenle, her zaman parametreli sorgular kullanarak veya ORM araçlarıyla çalışarak kullanıcı girişlerini güvenli bir şekilde işlemek önemlidir. Bu yöntemler, kullanıcı tarafından sağlanan verilerin doğrudan SQL sorgularına dahil edilmesini engeller ve böylece SQL enjeksiyonu riskini ortadan kaldırır.

Proxy sunucusu, iki bilgisayar veya bir bilgisayar ile bir internet kaynağı arasında aracı görevi gören bir sunucudur. Dikkat edersen client ile internet arasında bir sunucu diyor. Daha karşı sunucuya gitmedik. Bu aracı sunucu, istemci (kullanıcı) ile hedef sunucu (kaynak) arasında iletişimi sağlar. Proxy sunucuları çeşitli amaçlar için kullanılabilir, örneğin:

1. **Gizlilik ve Anonimlik**: Proxy sunucuları, kullanıcının IP adresini gizleyerek anonim kalmasını sağlar. Kullanıcı, internete proxy sunucusu üzerinden bağlandığında, hedef sunucu kullanıcının gerçek IP adresini değil, proxy sunucusunun IP adresini görür.

2. **Erişim Kontrolü**: Proxy sunucuları, belirli internet sitelerine veya hizmetlere erişimi kontrol edebilir. Örneğin, bir iş yeri veya okul, çalışanlarının veya öğrencilerinin belirli sitelere erişimini sınırlamak için proxy sunucuları kullanabilir.

3. **Önbellekleme**: Proxy sunucuları, sık kullanılan web sayfalarının kopyalarını önbelleğe alarak erişim sürelerini hızlandırabilir. Kullanıcı aynı sayfaya tekrar erişmek istediğinde, sayfa doğrudan proxy sunucusundan yüklenir, böylece ağ trafiği ve yükleme süresi azalır.

4. **Güvenlik**: Proxy sunucuları, zararlı web sitelerini veya içerikleri filtreleyerek kullanıcıların güvenliğini artırabilir. Ayrıca, şirketler iç ağlarını dış tehditlere karşı korumak için proxy sunucuları kullanabilirler.

5. **İçerik Filtreleme**: Proxy sunucuları, belirli içerik türlerini engelleyebilir veya belirli içerik türlerine öncelik verebilir. Bu, kullanıcıların uygun olmayan içeriklere erişimini kısıtlamak için kullanılabilir.

Proxy sunucularının farklı türleri vardır, örneğin:

- **İletici Proxy (Forward Proxy)**: Kullanıcı ile internet arasında bulunur ve kullanıcının isteklerini hedef sunucuya iletir.
- **Ters Proxy (Reverse Proxy)**: İnternet ile hedef sunucu arasında bulunur ve gelen istekleri hedef sunucuya iletir. Genellikle, web sunucularının güvenliğini ve performansını artırmak için kullanılır.

Proxy sunucuları, çeşitli ağ yapılandırmalarında farklı ihtiyaçları karşılamak üzere özelleştirilebilir ve yapılandırılabilir.
