Description: User access control refers to the policies and mechanisms that restrict access to resources based on the user’s identity. This process is fundamental for information security, as it ensures that only authorized individuals can access sensitive data or critical systems. Access control can be implemented through various techniques, with multifactor authentication being one of the most effective. The latter combines multiple verification methods, such as passwords, security tokens, and biometrics, to ensure that access is granted only to legitimate users. The main features of access control include user identification, authentication of their identity, and authorization to access specific resources. The relevance of this control lies in its ability to prevent unauthorized access, protect data integrity, and comply with security regulations. In an increasingly digitalized world, where cyber threats are prevalent, access control becomes an essential tool for safeguarding information and maintaining trust in technological systems.
History: Multifactor authentication (MFA) began to take shape in the 1980s when organizations started to recognize the need for more secure methods to protect access to their systems. However, its popularity grew significantly in the 2000s, driven by the rise of cyber threats and the need to comply with stricter security regulations. Key events, such as data breaches at major companies, led to the widespread adoption of MFA as a standard security measure.
Uses: Multifactor authentication is used in various applications, from accessing online banking accounts to enterprise management systems and corporate networks. It is common in services that handle sensitive information, such as corporate emails, e-commerce platforms, and healthcare systems. Additionally, many organizations implement MFA to protect access to their internal networks and critical systems.
Examples: Examples of multifactor authentication include using a password along with a code sent to a mobile phone or combining a fingerprint and a PIN to access mobile devices. Services like Google, Microsoft, and online banks offer MFA as an option to enhance the security of user accounts.
