Intranet.

An intranet is a private and internal network that uses internet technology and protocols to connect and share information within an organization. It is a closed network accessible only to authorized users, typically employees of an organization.

Use of intranet.

Intranets are used primarily for sharing information and resources within the organization, that is, among the employees. This includes documents, databases, company news, and internal communication tools.

Intranets often include collaboration tools, for instance, Wikis, shared calendars, and project management systems, to facilitate teamwork within the organization. They offer a controlled and secure environment, as only authorized personnel can access the intranet, reducing the risk of external threats.

Access Control.

• Intranets have strict access controls.

• Employees must have valid credentials to log in, and their access may be restricted to certain parts of the intranet depending on their roles and permissions.

Content.

The contents are usually confidential and intended for internal use only. Examples are sensitive company data, employee directories, HR policies, and other proprietary information.

Security.

Examples of security measures are Firewalls, encryption, and user authentication. These are important to protect the intranet from unauthorized access and external threats.

Extranet.

This is a controlled network that extends beyond the boundaries of an organization to include authorized external users, such as suppliers, partners, customers, or other third parties. Practically, it is a private extension of the intranet.

Uses.

Extranets facilitate collaboration and data sharing between an organization and its external stakeholders. This can include sharing product information, inventory data, or project updates with partners.

Many companies use extranets to manage supply chains, allowing suppliers to access inventory information, submit orders, and track shipments.

Some businesses provide customers with extranet access for services such as account management, order tracking, or online support.

Access Control.

Extranets have more complex access control systems compared to intranets. Access is granted to external parties with specific permissions, and it's usually limited to certain sections or data within the extranet.

Content.

Extranets contain a mix of internal and external content. While some information may be proprietary and confidential, other data is shared with trusted partners or customers.

Security.

Security is crucial in extranets, especially due to the involvement of external parties. Encryption, firewalls, and secure login systems are used to protect data and maintain confidentiality.
