Glossary

address: An IP address (logical address) or the address of a physical interface (hardware address). An Ethernet address is sometimes called a MAC address. See also IP address.

aggressive mode: A way to establish a secure channel during IPSec phase 1 negotiations when the VPN peer uses its identity as part of the authentication process. See also main mode.

AH, Authentication Header: An IPSec security protocol. Fortinet IPSec uses ESP in tunnel mode, not AH. See ESP.

ARP, Address Resolution Protocol: A protocol that resolves a logical IP address to a physical Ethernet address.

authentication: A process whereby a server determines whether a client may establish a connection and access private resources.

CA, Certificate Authority: A company that issues digital certificates to validate the identity of a person or entity in an online exchange.

CHAP, Challenge Handshake Authentication Protocol: An authentication protocol supported by PPP. See also PPP.

client: An application that requires and requests services from a server.

cluster: A group of servers configured to act as a single fault-tolerant unit.

connection: A link between computers, applications, or processes that can be logical, physical, or both.

decryption: A method of decoding an encrypted file into its original state.

DHCP, Dynamic Host Configuration Protocol: An Internet protocol that assigns IP addresses to network clients, usually when the client connects to the Internet.

Diffie-Hellman: An algorithm for establishing a shared secret key over an insecure medium. See Diffie- Hellman group.

Diffie-Hellman group: FortiGate units support Diffie- Hellman groups 1, 2 and 5. The size of the modulus used to calculate the key varies according to the group:

Group 1: 768-bit modulus

Group 2: 1024-bit modulus

Group 5: 1536-bit modulus

digital certificate: A digital document that guarantees the identity of a person or entity and is issued by a CA.

DMZ, Demilitarized Zone: An untrusted area of a private network, usually used to host Internet services without allowing unauthorized access to an internal (private) network. Typically, the DMZ contains servers accessible to Internet traffic, such as Web, FTP, SMTP, and DNS servers.

DMZ interface: The FortiGate interface that connects to a DMZ network.

DNS, Domain Name System: A service that converts symbolic node names to IP addresses. A domain name server (DNS server) implements the protocol.

DoS, Denial-of-Service: An attempt to disrupt a service by flooding the network with fake requests that consume network resources.

DSL, Digital Subscriber Line: A way to access the Internet at higher speeds using existing copper telephone lines. Users can maintain a continuous connection to the Internet and use the phone simultaneously.

encapsulate: Add a header to a packet to create a unit of transmission that matches the unit of transmission on a different network layer.

encryption: A method of encoding a file so that it cannot be understood. The information must be decrypted before it can be used.

endpoint: The IP address or port number that defines one end of a connection.

ESP, Encapsulated Security Protocol: An IPSec security protocol that provides encapsulation of encrypted data—IP packets are embedded in other IP packets so that the originating source and destination IP addresses cannot be seen on the Internet.

As part of the FortiGate series, the 100A combines advanced security features with powerful hardware capabilities, making it suitable for small to medium-sized businesses.

One of the key features of the Fortinet 100A is its deep packet inspection technology. This capability allows the firewall to analyze both the header and payload of packets traversing the network, enabling it to detect and block malicious content effectively. The 100A can identify and mitigate a wide range of threats, including malware, intrusions, and application-layer attacks.

The FortiOS operating system powers the Fortinet 100A, offering a robust and user-friendly interface for configuration and management. With its unified security management console, administrators can efficiently monitor network traffic and enforce security policies across the organization. The system provides centralized logging and reporting features, enabling users to gain valuable insights into their security posture and respond swiftly to incidents.

The 100A supports multiple deployment modes, including transparent, NAT, and route modes. This flexibility allows organizations to integrate the device into their existing network architecture with ease. The firewall's high throughput capabilities ensure that network performance remains unaffected, even under heavy load from multiple users and devices.

Another notable aspect of the Fortinet 100A is its support for various VPN technologies, including IPsec and SSL VPN. This feature facilitates secure remote access for employees, enabling them to connect to the corporate network safely, regardless of their location. As remote work continues to be a norm in many sectors, this capability is critical for maintaining productivity and security.

In addition to these features, the Fortinet 100A provides comprehensive web filtering capabilities, protecting users from harmful websites and inappropriate content. This protection is essential for organizations looking to maintain a secure and productive environment.

With its combination of powerful security features, flexible deployment options, and robust performance, the Fortinet 100A stands out as an ideal solution for organizations seeking to bolster their cybersecurity measures while ensuring seamless connectivity for users. As cyber threats continue to evolve, investing in a capable device like the FortiGate 100A is crucial for maintaining a secure network infrastructure.
