📌 Input Filters Summary
Input filters are tools or processes that check and clean data before it is used or stored by a system. They help make sure that only valid and safe information gets through. This protects software from errors, security risks, or unwanted data. Input filters are commonly used in web forms, databases, and applications to prevent issues like spam, incorrect entries, or attacks. They can remove unwanted characters, check for correct formats, or block harmful code. By filtering inputs, systems can run more smoothly and safely.
🙋🏻♂️ Explain Input Filters Simply
Imagine a security guard at a concert entrance checking tickets to make sure only people with valid tickets get in. Input filters work the same way for computer systems, letting in only good and safe information and keeping out anything that might cause problems. This keeps the system safe and working as it should.
📅 How Can it be used?
Input filters can be used to validate and sanitise user-submitted data in an online registration form to prevent errors and security risks.
🗺️ Real World Examples
A website that lets users create accounts uses input filters to check email addresses and passwords. The filters make sure the email is in the correct format and the password meets security requirements. They also block any code that could be used for hacking, ensuring only safe and valid information is stored.
An online shop uses input filters in its search bar to prevent users from entering harmful code or symbols. This stops attackers from trying to break into the system and helps provide accurate search results to genuine customers.
✅ FAQ
Why are input filters important when filling in online forms?
Input filters help keep online forms safe and reliable. They stop people from submitting information that does not make sense or could harm the system, like strange symbols or hidden code. This means your details are stored correctly, and everyone using the site has a better and safer experience.
How do input filters help protect against spam and harmful attacks?
Input filters block suspicious data before it can reach a website or app. For example, they can spot and remove spam messages or code that could try to hack a system. By doing this, they help keep websites running smoothly and protect your personal information.
Can input filters stop mistakes in the information we enter?
Yes, input filters can spot common mistakes, like typing letters in a phone number or leaving out important details. They help make sure the information you enter is in the right format, which saves time and prevents problems later on.

Cybersecurity (70 Topics)
Cybersecurity is the practice of protecting computers, networks, and data from unauthorised access, damage, or theft. It involves using technology, processes, and policies to keep information safe and ensure systems work as intended. The goal is to prevent attacks such as hacking, viruses, and data breaches that can put people or organisations at risk.
Secure Coding Standards
Secure coding standards are a set of guidelines and best practices that help software developers write code that prevents security vulnerabilities. These standards cover common risks such as data leaks, unauthorised access, and code injection. By following secure coding standards, developers reduce the chances of attackers exploiting weaknesses in software.
Sustainability in Digital Planning
Sustainability in digital planning means designing and implementing digital systems or projects in ways that consider long-term environmental, social, and economic impacts. It involves making choices that reduce energy consumption, minimise waste, and ensure digital solutions remain useful and accessible over time. The goal is to create digital plans that support both present and future needs without causing harm to people or the planet.
Rollback Triggers
Rollback triggers are automated actions set up in a database to undo changes when certain conditions are not met or when errors occur. They help maintain data accuracy by reversing transactions that could cause problems or inconsistencies. Rollback triggers are especially useful in systems where data integrity is critical, such as financial or inventory applications.
Identity Governance
Identity governance is the process organisations use to manage digital identities and control access to resources within their systems. It ensures that the right people have the appropriate access to the right resources, at the right time, for the right reasons. This involves setting policies, monitoring activity, and making sure access is updated or removed as roles change or people leave.
