IT Pros’ Job Interview Cheat Sheet of Multi-Factor Authentication (MFA)

Internet Climate

Recently, as hacking has become a business model and identity theft an everyday phenomenon, there is increasing hostility in Internet and an escalating concerns for PC and network securities. No longer is a long and complex password sufficient to protect your assets. In addition to a strong password policy, adding MFA is now a baseline defense to better ensure the authenticity of an examined user and an effective vehicle to deter fraud.

Market Dynamics

Furthermore, the increasing online ecommerce transactions, the compliance needs of regulated verticals like financial and healthcare, the unique business requirements of market segments like the gaming industry, the popularity of smartphones, the adoption of cloud identity services with MFA technology, etc. all contribute to the growth of MFA market. Some market research published in August of 2015 reported that “The global multi-factor authentication (MFA) market was valued at USD 3.60 Billion in 2014 and is expected to reach USD 9.60 Billion by 2020, at an estimated CAGR of 17.7% from 2015 to 2020.”

Strategic Move

While mobility becomes part of the essential business operating platform, a cloud-based authentication solution offers more flexibility and long-term benefits.The is apparent The street stated that

“Availability of cloud-based multi-factor authentication technology has reduced the maintenance costs typically associated with hardware and software-based two-factor and three-factor authentication models. Companies now prefer adopting cloud-based authentication solutions because the pay per use model is more cost effective, and they offer improved reliability and scalability, ease of installation and upgrades, and minimal maintenance costs. Vendors are introducing unified platforms that provide both hardware and software authentication solutions. These unified platforms are helping authentication vendors reduce costs since they need not maintain separate platforms and modules.”

Disincentives

Depending on where IT is and where IT wants to to be, the initial investment may be consequential and significant. Adopting various technologies and cloud computing may be necessary, while facing resistance to change in corporate IT cultural.

Closing Thoughts

MFA helps ensure the authenticity of a user. MFA by itself nevertheless cannot stop identity theft since there are various ways like key logger, phishing, etc. to steal identity. Still, as hacking has become a business model for some underground industry, and even a military offense, and credential theft has been developed as a hacking practice, it is not an option to operate without a strong authentication scheme. MFA remains arguably a direct and effective way to deter identity theft and fraud.

And the emerging trend of employing biometrics, instead of a password, with a key-based credential leveraging hardware and virtualization-based security like Device Guard and Credential Guard in Windows 10 further minimizes the attack surface by ensuring hardware boot integrity and OS code integrity, and allowing only trusted system applications to request for a credential. Device Guard and Credential Guard together offers a new standard in preventing PtH which is one of the most popular types of credential theft and reuse attacks seen by Microsoft so far.

Above all, going forward we must not consider MFA as an afterthought and add-on, but an immediate and imperative need of a PC security solution. IT needs to implement MFA sooner than later, if not already.
