Description: Security techniques are methods used to protect systems from threats, ensuring the integrity, confidentiality, and availability of information. In the cloud context, the Zero Trust approach has become a fundamental pillar. This security model is based on the premise that no entity, whether internal or external, should be trusted by default. Instead of assuming that everything within the network is safe, Zero Trust requires continuous verification of every user and device attempting to access resources. This involves implementing multiple layers of security, such as multi-factor authentication, network segmentation, and constant activity monitoring. Security techniques also encompass the use of encryption to protect data in transit and at rest, as well as identity and access management to ensure that only authorized users can access sensitive information. The relevance of these techniques lies in the increasing sophistication of cyber threats and the need to protect digital assets in an environment where remote work and cloud computing are becoming more common.
History: The concept of Zero Trust was introduced by John Kindervag in 2010 while working at Forrester Research. Since then, it has evolved in response to the increasing complexity of IT infrastructures and the rise of security breaches. As organizations adopted cloud computing and remote work, the need for a more rigorous approach to security became evident, leading to the widespread adoption of the Zero Trust model across various industries.
Uses: Security techniques, especially within the Zero Trust framework, are used to protect sensitive data in cloud environments, manage access, and continuously authenticate users. They are applied in organizations handling critical information, such as financial institutions, healthcare organizations, and technology companies, where data protection is paramount.
Examples: A practical example of Zero Trust implementation is the use of multi-factor authentication in online banking services, where users must provide multiple forms of verification before accessing their accounts. Another case is network segmentation in technology companies, which restricts access to sensitive data only to those employees who truly need it to perform their jobs.
