SQL Injection

SQL Injection

๐Ÿ“Œ SQL Injection Summary

SQL Injection is a type of security vulnerability that occurs when an attacker is able to insert or manipulate SQL queries in a database via input fields in a website or application. This allows the attacker to access, modify, or delete data in the database, often without proper authorisation. SQL Injection can lead to serious data breaches, loss of sensitive information, and potential damage to an organisation’s reputation.

๐Ÿ™‹๐Ÿปโ€โ™‚๏ธ Explain SQL Injection Simply

Imagine you are filling out a form on a website, and instead of entering your name, you write a special command that tricks the website into showing you secret information. SQL Injection is like finding a way to sneak past a locked door using a clever trick, rather than the key.

๐Ÿ“… How Can it be used?

In a web application project, developers must validate and sanitise user input to prevent attackers from injecting harmful SQL commands.

๐Ÿ—บ๏ธ Real World Examples

An online store has a search box that directly uses user input in its database queries. An attacker enters a specially crafted search term that tricks the store into revealing confidential customer data, such as email addresses or credit card numbers.

A company employee portal allows staff to log in with a username and password. If the login form is not properly secured, an attacker could use SQL Injection to bypass authentication and gain access to private employee records.

โœ… FAQ

What is SQL Injection and why should I be concerned about it?

SQL Injection is a way for attackers to trick a website or app into running unwanted commands on its database. This can let them peek at, change, or even delete information they should never have access to. If it happens, private details could get out, and businesses might lose trust or face big problems.

How do attackers use SQL Injection to access information?

Attackers use SQL Injection by entering special commands into search boxes or forms where you would normally type your details. If a website does not check this input properly, the attacker can sneak past the normal rules and get the database to share information it should keep private.

Can SQL Injection be stopped, and how do websites protect themselves?

Yes, websites can prevent SQL Injection by making sure they check and clean up anything users type in before using it in a database. Using secure methods to ask the database for information, like prepared statements, makes it much harder for attackers to break in.

Voice of the Customer (VoC) Analysis

Voice of the Customer (VoC) Analysis is the process of collecting and examining feedback from customers about their experiences, needs, and expectations with a product or service. It involves gathering information from surveys, reviews, support interactions, and social media to understand what customers value and where improvements can be made. The goal is to use these insights to guide decisions that enhance customer satisfaction and loyalty.

Digital Ethics in Business

Digital ethics in business refers to the principles and standards that guide how companies use technology and digital information. It covers areas such as privacy, data protection, transparency, fairness, and responsible use of digital tools. The aim is to ensure that businesses treat customers, employees, and partners fairly when handling digital information. Companies following digital ethics build trust by being open about their practices and respecting people's rights in a digital environment.

Privileged Access Management

Privileged Access Management, or PAM, is a set of tools and practices used by organisations to control and monitor who can access important systems and sensitive information. It ensures that only authorised individuals have elevated permissions to perform critical tasks, such as changing system settings or accessing confidential data. By managing these special permissions, businesses reduce the risk of security breaches and accidental damage.

Network Segmentation

Network segmentation is the practice of dividing a computer network into smaller, isolated sections. Each segment can have its own security rules and access controls, which helps limit the spread of threats and improves performance. By separating sensitive systems from general traffic, organisations can better manage who has access to what.

Dynamic Layer Optimization

Dynamic Layer Optimization is a technique used in machine learning and neural networks to automatically adjust the structure or parameters of layers during training. Instead of keeping the number or type of layers fixed, the system evaluates performance and makes changes to improve results. This can help models become more efficient, accurate, or faster by adapting to the specific data and task requirements.
