# Security and Privacy Infrastructure

Security and privacy are considered paramount during the design of Cerebrum Cloud. It guarantees the security and compliance of data with relevant regulations by implementing a multi-layer approach:

* **Encryption**: Encryption: Data encryption both in transit and at rest is ensured by industry-standard encryption algorithms. This makes it difficult for the data to be exposed to unauthorized people, even in cases of interception.
* **Access Control**: Cerebrum Validators can enforce fine-grained access to sensitive data and models based on users' roles, permissions, enabling only those resources which are accessible for authorized users or agents to decrease the likelihood of a data breach.
* **Zero-Trust Architecture**: In the previously defined architecture, any interaction within the network is authenticated and authorized to reduce the chance of unauthorized access. This will make it impossible for a malicious actor who gets into the network to perform any unauthorized action or access sensitive data.
* **Compliance**: Cerebrum Cloud is designed to be compliant with relevant data privacy regulations, therefore giving the enterprise confidence that their data is handled responsibly. This platform provides an organization with a set of tools and features to help organizations meet their compliance obligations, such as data anonymization and audit trails.
* **Secure Model Deployment:** The models are then deployed in the compute nodes' secure enclaves to prevent exposure to unauthorized access or modifications. This will make sure that integrity and confidentiality of the models operating on a decentralized network are guaranteed.

In addition to the above mentioned security features, Cerebrum implements additional security mechanisms such as:

* Regular Penetration Testing: Regular penetration testing is run by Cerebrum for the uncovering of vulnerabilities that may arise within the system.
* Secure Coding Practices: Secure coding practices are adopted during development in order to decrease the chances of software vulnerabilities.
