Notes: Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here. IBM hardware products are manufactured from new parts, or new and serviceable used parts. Regardless, our warranty terms apply. All customer examples cited or described in this presentation are presented as illustrations of the manner in which some customers have used IBM products and the results they may have achieved. Actual environmental costs and performance characteristics will vary depending on individual customer configurations and conditions. This publication was produced in the United States.

Note: This requirement is a best practice until January 31, 2018, after which it becomes a requirement. NIST SP 800-171 3.5.3 Use multifactor authentication for local and network access to privileged accounts and for network access to non-privileged accounts. Note: Network access is any access to an information system by a user (or a process acting on behalf of a user) communicating through a network (e.g., local area network, wide area network, Internet). Note: This requirement is effective December 31, 2017. 7 © 2018 IBM Corporation Why MFA is needed • We need to be sure the person logging in is you! A single factor alone is more susceptible to unauthorized use. • To better secure your systems, application, and data, by thwarting attacks of only a single factor. • Payment Card Industry (PCI) requires it for things such as remote access and administrative access to the card data environment • Requirements for access to Federal Government systems • Possibly to follow your own corporate security policy • MFA is especially important for privileged administrative accounts. • To be smart and secure your data! 8 © 2018 IBM Corporation Authentication is a journey Moving to stronger, easier authentication Capture SOMETHING THAT YOU KNOW SOMETHING THAT YOU HAVE SOMETHING THAT YOU ARE - Usernames and passwords - ID Badge - Biometrics - PIN Code - One time passwords - Knowledge questions - Time-based - Email / SMS 9 © 2018 IBM Corporation What is multi-factor authentication (MFA) • Authentication with more than one factor such as a password or a key to gain access • A factor could be something only you know (ie password), something only you have (ie key fob), or something only you are (i.e. biometrics) • ATM Card and PIN – Something you have and something you know • More factors generally mean more security, as if one factor is compromised such as a password, more factors are still required to successfully authentication • There is a distinction between multi-factor authentication
