OAI - Review Lesson

Review

The Internet is a complex system with many abstractions. It operates as an "Open Access" system using common protocols. The TCP/IP Internet Protocol Suite is the main communication protocol system for transporting data on the Internet. It is a four layer system composed of the Application layer, Transport layer, Internet layer, and Network layer. Each layer of the TCP/IP model provides a specific function and purpose. The "open access" system provides equal access to everyone.  As more and more personal information is stored on the Internet, the need to secure the data has risen. Internet security (https and ssl) is supported by both symmetric and public key cryptography. The current symmetric standard is the Advanced Encryption Standard. Certificate of Authorities (CAs) issue digital certificates that validate the ownership of encryption keys and are based on a trust model. The need for Cybersecurity professionals has risen due to the increase in security breaches due to vulnerabilities systems. Vulnerabilities can be caused by hardware, software, network, or company personnel.
