You want to keep your data secure. How can you ensure your information is protected?

The importance of strong passwords cannot be overstated in securing personal and organizational data. Research has shown that 81% of data breaches are due to either weak, stolen, or default passwords; underscoring the need for robust password practices. I suggest not only adhering to the recommended complexity and uniqueness of passwords but also implementing multi-factor authentication (MFA) wherever possible. MFA adds an additional layer of security by requiring two or more verification methods to gain access to an account, significantly reducing the likelihood of unauthorized access. This combination of strong, unique passwords managed through a reliable password manager, alongside the application of MFA.

Employ strong encryption, use robust authentication methods, and regularly update security measures. Implement access controls, conduct regular audits, and educate users on safe practices to safeguard data effectively.

O maior segredo para usar senhas fortes é ter um cofre de senhas. Existem inúmeros no mercado, inclusive na nuvem (você pode usar no celular e computador). Dessa forma, você só precisa lembrar a senha para acessar o cofre, e as demais senhas estarão lá dentro. É muito mais fácil lembrar apenas uma senha, enquanto as outras podem ser senhas de 30 caracteres totalmente aleatórias.

Hide it .. Our grandparents hid stuff they didn't want found. We seem to have forgotten that idea. There is a lot to be said for distributed data storage.

One of the fundamental steps to keep your data secure is to use strong passwords. Create passwords that are complex, combining uppercase and lowercase letters, numbers, and special characters. Avoid using easily guessable information like your name or birthdate. Additionally, use unique passwords for different accounts to prevent a domino effect if one is compromised. Regularly update your passwords and consider using a reputable password manager to generate and store complex passwords securely. Strong, unique passwords act as a crucial first line of defense against unauthorized access to your accounts and sensitive information.

Ensure that data is stored if possible in an on prem server/storage. Though cloud is secure but, on prem gives you more control. Encrypt data using strong cypher suites and using a random key as part of appended input to data and another random key as part of DEK itself. Encrypt the DEK with another key KEK and if possible store KEK as part of external device so as to isolate the data and key.

Encrypting your data adds an extra layer of protection, ensuring that even if unauthorized access occurs, the information remains unreadable without the appropriate decryption key. Use encryption tools or enable built-in encryption features on your devices and communication channels. For example, encrypt the files on your computer or use end-to-end encryption for messaging apps. Full-disk encryption is another powerful measure, protecting all the data on your device. By implementing encryption, you safeguard your data from potential threats during transmission or if your device falls into the wrong hands.

Encryption protects your data both during transit and storage, ensuring that unauthorized users cannot access it. Only authorized parties have access to encrypted data. It is also crucial to utilize robust encryption techniques such as AES and TLS to ensure data security and confidentiality. "The longer the encryption key, the more difficult it becomes for an attacker to break it."

Encryption control is the key factor to achieve your information security goals, there are multiple encryption mathods available, you can implement according to the nature of your data. For data at rest AES 256 is a good example and for data in motion you can consider SSL and TLS. If you wants to implement high level encryption you can consider hybrid cryptographic control to secure your data.

- Adopt Strong Standards: Use reliable encryption algorithms like AES for stored data and TLS for data in transit. - Universal Application: Apply encryption to all data, whether on devices, in the cloud, or during transmission. - Key Management: Securely manage your encryption keys, possibly using a key management service for enhanced control. - Educate: Ensure all users understand how to properly use encryption tools to prevent data exposure. - Stay Updated: Regularly review and update your encryption methods to align with the latest security standards. By focusing on these essentials, you'll significantly increase the security of your data against unauthorized access or interception.
