SQL an Introduction

-

Programming language SQL (Structured Query Language) is used. It enables the execution of operations such data creation, modification, access, and deletion as well as data querying and inserting. Based on predetermined criteria, it enables data extraction and filtering. To access, manage, and update data stored in databases connected with SQL Server, Relational Database Management Systems (RDBMS) like MS SQL Server Express, Oracle SQL Server, MySQL, and PostgreSQL are utilized.

The following are general tasks:

To Create databases or tables or columns Modify databases or tables or columns Insert, update and delete data in a database Store data into database Retrieve data from a database Filter, sorting and grouping data in a database Join multiple tables to combine data to from a new table Create views, indexes, triggers, stored procedures and user-defined functions to automate tasks and performance enhancement

Industries: Manufacturing or production, software, finance, healthcare and e-commerce to manage and analyze data.

The language supports SELECT, INSERT, UPDATE, DELETE, JOIN, GROUP BY, and ORDER BY commands and functions.

One of the key programming tools for server administrators, data scientists, software developers, SQL Server database administrators, and ERP developers.

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
