📌 Content Security Policy (CSP) Summary
Content Security Policy (CSP) is a security feature in web browsers that helps prevent malicious scripts and other harmful content from running on websites. It works by letting website owners specify which sources of content are allowed to be loaded, such as images, scripts, and stylesheets. By setting these rules, CSP can stop many types of attacks, including cross-site scripting and data theft.
🙋🏻♂️ Explain Content Security Policy (CSP) Simply
Imagine your website is a party, and CSP is the guest list at the door. Only people (scripts and content) on the list can get in, so unwanted troublemakers are kept out. This helps keep your party safe and stops gatecrashers from causing problems.
📅 How Can it be used?
A developer can use CSP to restrict which scripts and resources are allowed to load on their website, reducing security risks.
🗺️ Real World Examples
An online banking site uses CSP to only allow scripts from its own servers and trusted partners. This blocks attackers from injecting malicious code that could steal user passwords or redirect funds.
A news website implements CSP to prevent unauthorised third-party advertisements from running scripts that could track users or display fake competitions, protecting both the site and its visitors.
✅ FAQ
What is Content Security Policy and why is it important for websites?
Content Security Policy is a set of rules that website owners can use to tell browsers which content is allowed to load on their site. This is important because it helps stop harmful scripts and code from running, which can protect visitors from attacks like stealing information or redirecting them to unsafe pages.
How does Content Security Policy help protect me when I visit websites?
When a website uses Content Security Policy, it limits where scripts, images, and other resources can come from. This means that if a hacker tries to sneak in malicious code from an unauthorised source, the browser will block it, making your browsing experience safer.
Can using Content Security Policy affect how a website looks or works?
Yes, if Content Security Policy is set up too strictly, it might block some images or scripts that the website actually needs to display or function properly. Website owners need to find the right balance so that their site stays secure without breaking features that visitors expect.

Control Flow Integrity
Control Flow Integrity, or CFI, is a security technique used to prevent attackers from making a computer program run in unintended ways. It works by ensuring that the order in which a program's instructions are executed follows a pre-defined, legitimate path. This stops common attacks where malicious software tries to hijack the flow of a program to execute harmful code. CFI is especially important for protecting systems that run code from multiple sources or that handle sensitive data, as it helps block exploits that target vulnerabilities like buffer overflows.
Continuous Deployment
Continuous Deployment is a software development process where code changes are automatically released to production as soon as they pass all required tests. This removes the need for manual intervention between development and deployment, making updates faster and more reliable. It helps teams respond quickly to user needs and reduces the risks of large, infrequent releases.
Inventory Optimisation Tools
Inventory optimisation tools are software solutions that help businesses manage their stock levels efficiently. They use data and algorithms to predict demand, reduce excess inventory, and prevent stockouts. These tools support better decision-making by automating calculations and providing clear insights into inventory needs.
Digital Benefits Realisation
Digital benefits realisation is the process of making sure that the promised advantages of a digital project are actually achieved. It involves planning, tracking, and measuring the positive changes that come from using new digital tools or systems. The aim is to ensure that investments in technology lead to real improvements, such as saving time, reducing costs, or improving services.
Proof of Elapsed Time
Proof of Elapsed Time, often shortened to PoET, is a consensus mechanism used in blockchain networks to decide who gets to add the next block of transactions. It relies on trusted computing environments to randomly assign wait times to participants. The participant whose wait time finishes first gets to create the next block, which helps ensure fairness and energy efficiency compared to systems that require lots of computing power.
