Cisco Cisco Email Security Appliance C380 Notas de publicación

AsyncOS 7.5 adds a new predefined Technician role for users responsible for 
upgrading Cisco IronPort Email Security appliances. Users assigned to the 
technician role can perform system upgrades, reboot the appliance, manage 
feature keys, and perform other actions needed to upgrade an appliance. 

Starting in AsyncOS 7.5, administrators can perform system upgrades, create 
clusters, and join appliances to existing clusters.

In AsyncOS 7.5, you can define user account and password restrictions to enforce 
organizational password policies for local Email Security appliance users. These 
restrictions include:

Password rules. You can define what kinds of passwords users can choose, 
such as which characters are optional or mandatory.

User account locking. You can define how many failed login attempts cause 
the user to be locked out of the account. 

Password lifetime rules. You can define how long a password can exist 
before the user is required to change the password after logging in.

AsyncOS 7.5 improves how anti-spam scanning handles large messages in order 
to optimize the throughput of your Email Security appliance while still being able 
to scan the increasing number of larger messages. You can define an always scan 
message size, where messages smaller than the defined size are completely 
scanned by IronPort Anti-Spam engine, delivering IronPort’s industry-leading 
level of efficacy, and a never scan message size, where messages larger than the 
defined size are not scanned. For messages larger than the always scan size and 
smaller than the never scan size, the anti-spam engine performs a limited and 
faster scan.
