True security is only possible if data and channels are protected with modern algorithms encryption when using strong passwords. With patience, you can open ZIP files by brute-force, and many web services do not use any encryption at all when processing login credentials. Windows passwords are stored in system memory and provide protection only if no other access path is available, such as network or USB booting. In fact, the truth is this: everything that is processed or stored in open form(as is the case with the examples just listed), you can work around. Most systems are not secure, although well-known 'security' features such as Windows passwords, ZIP passwords, BIOS passwords and FTP / Web imply security. And here we came across a very interesting solution: TrueCrypt. What happens if an intruder gains access to your personal files? What if someone else finds information that is only for your eyes? Whether it is personal data or business files, important information must be protected. In the meantime, many users do not have a real scenario to secure their data. A growing number of operating system and web service functions provide more options for accessing, modifying (and losing) data. Data protection is a very important and urgent topic.
