Applications have a close relationship with data and its storage. This is because applications basically consist of managing data in order to make it possible to optimize the business using automation tasks, helping with decision-making, organizing tasks, and managing certain areas. Also, many companies need to store delicate data and validate access control. Over time, the demand for security software grew significantly, and many companies increasingly invested in creating safe applications. An integral element of security is security information, which follows these basic principles:

• Confidentiality: The data should not be accessible to non-authorized users or to any entities that request access to the data.
• Integrity: The data cannot be updated or modified in a non-authorized manner.
• Availability: The data should be available when it is needed.
• Non-repudiation: Users cannot repudiate or deny the relation using data or any other process.

For an application to be safe, it needs to provide at least these basic principles.

Security patterns are a set of solutions to common security problems that occur over and over. A large part of these security patterns works to solve problems about authentication, which is associated with confidentiality and integrity principles. With security patterns, the developer can write software with a high level of security for targeting known problems and issues using solutions that are tested and validated.
