AUTOMATIC TRANSFER SWITCH
127
– The default server certificate on the Automatic Transfer Switch has
the Automatic Transfer Switch’s serial number in place of a valid
common name (the DNS name or the IP address of the Automatic
Transfer Switch). Therefore, although the Automatic Transfer Switch
can control access to its Web interface by user name, password,
and account type (e.g., Administrator, Device Manager, or Read-
Only User), the browser cannot authenticate what Automatic
Transfer Switch is sending or receiving data.
– The length of the public key (RSA key) that is used for encryption
when setting up an SSL session is only 768 bits. (The public key
used in Methods 2 and 3 is 1024 bits, providing more complex
encryption and consequently a higher level of security.)
