๐ Mandatory Access Control (MAC) Summary
Mandatory Access Control, or MAC, is a security framework used in computer systems to strictly regulate who can access or modify information. In MAC systems, access rules are set by administrators and cannot be changed by individual users. This method is commonly used in environments where protecting sensitive data is crucial, such as government or military organisations. MAC ensures that information is only accessible to people with the correct clearance or permissions, reducing the risk of accidental or unauthorised data sharing.
๐๐ปโโ๏ธ Explain Mandatory Access Control (MAC) Simply
Imagine a school where only the headteacher decides which students can enter certain classrooms, and no student or teacher can change those decisions. The rules are strict and enforced by the headteacher, so everyone must follow them. Mandatory Access Control works the same way for computer files and resources, making sure that only the right people can get in, based on rules set by someone in charge.
๐ How Can it be used?
Use Mandatory Access Control to ensure only authorised employees can access confidential files in a company database.
๐บ๏ธ Real World Examples
A government agency uses Mandatory Access Control to protect classified documents. Only employees with the right security clearance can access certain files, and even high-ranking staff cannot alter these rules without going through strict administrative procedures. This helps prevent leaks or unauthorised access to sensitive information.
A hospital implements Mandatory Access Control to restrict access to patient medical records. Doctors and nurses can only view records relevant to their patients, while administrative staff are limited to non-medical information. This reduces the risk of privacy breaches and helps the hospital comply with health data regulations.
โ FAQ
What is Mandatory Access Control and why is it important?
Mandatory Access Control, or MAC, is a way of keeping sensitive information safe by letting only certain people access it. Instead of users deciding who can see what, the rules are set by administrators and cannot be changed. This is especially important in places like government or military organisations where keeping data secure is a top priority.
How does MAC differ from other ways of controlling access to information?
Unlike systems where users can set their own sharing rules, MAC puts all the control in the hands of administrators. This means users cannot change who can access or edit files, making it much harder for information to be shared by mistake or without permission.
Where is Mandatory Access Control commonly used?
MAC is most often used in environments where data security is absolutely essential, such as government agencies, military organisations, or companies handling highly sensitive information. By strictly controlling access, these organisations reduce the risk of leaks or unauthorised access.

Decentralized Oracle Integration
Decentralised oracle integration is the process of connecting blockchain applications to external data sources using a network of independent information providers called oracles. These oracles supply reliable data, such as weather updates, stock prices or sports results, which smart contracts on the blockchain cannot access directly. By using several oracles instead of just one, the system reduces the risk of errors or manipulation, making the data more trustworthy.
Incident Response Playbooks
Incident response playbooks are step-by-step guides that outline how to handle specific types of security incidents, such as malware infections or phishing attacks. They help organisations respond quickly and consistently by providing clear instructions on what actions to take, who should be involved, and how to communicate during an incident. These playbooks are designed to minimise damage and recover systems efficiently by ensuring everyone knows their roles and responsibilities.
Fishbone Diagram
A Fishbone Diagram, also known as an Ishikawa or cause-and-effect diagram, is a visual tool used to systematically identify the possible causes of a specific problem. It helps teams break down complex issues by categorising potential factors that contribute to the problem. The diagram looks like a fish skeleton, with the main problem at the head and causes branching off as bones.
Browser Isolation
Browser isolation is a security technique that separates web browsing activity from the rest of a computer or network. It works by running browser sessions in a secure, isolated environment, often on a remote server or a virtual machine. This way, if a user visits a malicious website, any harmful code or malware is contained and cannot affect the user's device or sensitive data. Organisations use browser isolation to protect against web-based threats, such as phishing attacks and drive-by downloads, without restricting access to the internet.
Secret Sharing Schemes
Secret sharing schemes are methods used to split a secret, such as a password or encryption key, into several parts or shares. Each share is given to a different person or system. Only when a certain number of these shares are combined can the original secret be reconstructed. This approach helps protect sensitive information by ensuring that no single person has access to the whole secret, reducing the risk of theft or misuse.
