A common security practice for protecting online data is utilizing encryption. Encryption transforms data into a format that is unreadable without a specific key, ensuring that unauthorized users cannot access sensitive information. This practice is vital for securing communications, transactions, and storage of confidential data across networks. Implementing encryption protocols, such as SSL/TLS for web traffic and AES for data storage, enhances data integrity and confidentiality. As cyber threats grow, encryption remains an essential measure for safeguarding personal and organizational information.
