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.
