Access control and encryption

This computer security diagram example was designed on the base of the diagram from the website of the Centers for Disease Control and Prevention (CDC). "Encryption and Cryptography Encryption converts plain text into ciphertext, and decryption converts ciphertext back into plain text. Ciphertext looks like random characters, but is actually the result of the application of a key to the plain text. A key is usually a mathematical algorithm known only to the sender and the intended recipient of the message. A cryptosystem is a system for encrypting and decrypting data. A strong cryptosystem has many possible keys, so a third party would be unlikely to find the correct key by trying all possible keys. A strong cryptosystem also produces ciphertext that appears random to all standard statistical tests and resists all known methods for breaking codes. Access Control Before implementing encryption, an organization needs to ensure access to the database is limited to authorized users. Access controls that should be addressed include rules for creating users, users’ privileges to access objects, and users’ permissions to perform commands and various tasks. The following diagram illustrates how access control and encryption work together to secure data" [cdc.gov/cancer/npcr/tools/security/encryption2.htm] The cybersecurity diagram example "Access control and encryption " was created using the ConceprDraw PRO software extended with the Network Security Diagrams solution from the Computer and Neworks area of ConceptDraw Solution Park.
