4.4.14 Security Configuration
In this section, several Layer 2 security mechanisms are provided to increase the security level of
your Managed Switch. Layer 2 attacks are typically launched by or from a device that is physically
connected to the network. For example, it could be a device that you trust but has been taken over
by an attacker. By default, most security functions available in this Managed Switch are turned off,
to prevent your network from malicious attacks, it is extremely important for you to set up
appropriate security configurations. This section provides several security mechanisms to protect
your network from unauthorized access to a network or redirect traffic for malicious purposes,
such as Source IP Spoofing and ARP Spoofing.
