What are the key measures that can be implemented to enhance security in cloud computing ? To overcome security issues in cloud computing, one can take the following measures: * Implementing strong authentication mechanisms, such as multi-factor authentication (MFA), adds an extra layer of security to cloud resources. For example, requiring users to provide something they know (password) and something they have (security token) for authentication significantly reduces the risk of unauthorized access. Example: A cloud service provider may offer MFA options, where users are required to enter their password and a unique code sent to their mobile device during login. This ensures that even if an attacker manages to obtain the password, they still need physical possession of the user's mobile device to gain access. * Encrypting sensitive data in transit and at rest protects it from unauthorized access. This ensures that even if an attacker intercepts or gains access to the data, it rema...
