The Office of the Chief Information Security Officer (OCISO) is working on deploying a number of initiatives aimed at further protecting the systems, data, and reputation of UCLA. 

One important initiative involves the implementation of an Email Multi-Factor Authentication (MFA) solution, which will improve the security of our Office 365 accounts. This is a critical initiative, as we have seen active exploits of email accounts across the UC system. Email MFA will add a layer of protection to our email accounts to prevent these types of activities from occurring.
