SQL Server Architecture

-

The architecture of SQL Server is based on the client-server model, where clients send requests to the server for accessing or modifying data stored in the database.

The SQL Server architecture consists of three main components: the client, the SQL Server instance, and the operating system.


Here is a brief explanation of each main component:

  1. Client: This component is responsible for sending requests to the SQL Server instance and receiving the results. The client can be any application or tool that can connect to SQL Server, such as SQL Server Management Studio, Visual Studio, .NET applications, web applications, desktop applications, and mobile apps. Client communicates with the SQL Server instance using a network protocol such as TCP/IP.

  2. SQL Server Instance: This component is the core of the SQL Server architecture. It includes the SQL Engine, which is responsible for processing SQL queries, and the storage engine, which is responsible for managing data storage and retrieval. The SQL Server instance also includes other services such as SQL Agent for scheduling jobs, Full-Text Search for text-based search capabilities, Integration Services for data integration and transformation, Analysis Services for data analysis and mining, and Reporting Services for creating reports.

  3. Operating System: This component provides the underlying infrastructure for SQL Server to operate. It includes the file system, memory management, and networking capabilities that SQL Server relies on. The operating system also provides security and access control features to ensure that SQL Server is protected from unauthorized access.

SQL Server is designed to provide a scalable, reliable, and secure database management system that can support a wide range of applications and workloads.

SQL Server architecture is a multi-layered system consisting of several components that work together to store, manage and retrieve data, allows for customization and integration with other systems, making it a popular choice for businesses of all sizes.

OWASP Top 10

OWASP Top 10 is an awareness document mentioning top 10 most critical risks in web application security which is regularly updated by an international non-profit organization called Open Web Application Security Project, dedicated to web application security. 1. Broken Access Control Broken access control vulnerability allows attackers to read / view sensitive data and carry out actions that they are not authorized to carry out. As an illustration, consider a website allows only admin users to view its admin pages and protected from regular users. If access control is compromised, an unauthorized user can read private data belonging to other users, gain access to admin and carry out actions that they are not intended to. Example of such type of vulnerability is Insecure Direct Object References (IDOR). Consider a user on a website uses following URL to access his / her account: https://xyz.com/user_acct?user_num=123 Using the URL, user retrieving his information from the database in th

TCP/IP Model

TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a standard protocol suite used to facilitate communication between network devices over the internet which consists of two components TCP and IP. TCP/IP is a compact form of OSI model. Unlike the OSI model, which has seven layers, it has four layers. The data is divided into packets by the TCP/IP Model at the sender's end, and in order to preserve data correctness, the same packets must be reassembled at the recipient's end. The data is divided into four layers by the TCP/IP paradigm, which arranges the data in a sequential fashion at the sender's end and reorders it at the recipient's end. Network Access Layer: A combination of Physical layer & Data Link layer defined in OSI model, responsible for the transmission of the data between two devices over network. Ethernet protocol is used by this layer. Network Layer / Internet Layer: It is responsible to send the packets from a network to the des

AAA

AAA stands for Authentication, Authorization & Accounting. AAA is an information security framework used for controlling access to computer resources, enforcing policies & tracking for auditing usage of resources required for billing of resources.                           AAA used to control which user is allowed to access the network resources by comparing user's login credentials (user id & password) with AAA server's database (Active Directory) stored user credential data called Authentication, authorize that user for performing a pre-defined task as per roles & responsibilities set in the database (enforcing policies) called Authorization and tracking the actions performed while accessing the network called Accounting. Here AAA server acts as an Identity & Access Management Tool. For example, administrator can access a network device by using console normally.  In case of accessing network device remotely, it can happen only by using IP address. But the
