Multi-factor Authentication (MFA) is a security measure that requires users to provide multiple forms of identity verification in order to gain access to their account. MFA is used commonly to keep companies’ cloud account secure and to prevent brute force hackers.
MFA requires that a user validates their identity with another vector in addition to providing the correct username and password. However, as cyber attackers have grown increasingly sophisticated, multi-factor authentication is no longer enough to prevent malicious intrusions.
The most important aspect to MFA is boosting authentication security.
The main benefit of MFA is that it will enhance your organization's security by requiring your users to identify themselves by more than a username and password. While important, usernames and passwords are vulnerable to brute force attacks and can be shared or stolen by third parties.
Implementing MFA in an enterprise's identity and access management (IAM) with something like a thumbprint or physical hardware key means increased confidence that your organization will stay safe from cyber criminals.
MFA is commonly based on three core authentication factor categories:
There are primarily two different types of authentication implementations today: Adaptive and passwordless.
Adaptive MFA is configured based on an evaluation of the users’ risk behavior. Depending on the users’ risk assessment, MFA is deployed to select the right authentication factors that are adapted to fit the situation.
Passwordless MFA occurs when password credentials are replaced with a more secure form of authentication, such as a fingerprint, PIN code, voice recognition, or signing in through a cell phone.
Multi-Factor Authentication is highly effective in stopping opportunistic actors from gaining unauthorized access to private and company resources.
Not using multi-factor authentication makes accounts more susceptible to cybersecurity threats such password spraying
The reality is, if you're not using MFA your organization is more at risk for attacks. A huge security threat today is the risk of compromised credentials. However, there are still ways to bypass MFA that must be taken into account, such as phishing and account hijacking.
As a key aspect to identity and access management (IAM) policy, MFA can thwart some of the most common cybersecurity threats such as:
MFA prevents cyberattackers from maliciously obtaining accounts by requiring secondary credentials and information from the user. Attackers can potentially obtain a user’s password, but it’s harder to obtain their biometrics or the answer to a personal security question.
While multi-factor authentication (MFA) was once the single best technique to reduce the possibility of a breach, breaches in cloud networks, like Microsoft Office 365, continue to occur. MFA security measures are no longer enough to deter malicious and insidious attacks. Of those attacks, account takeover breaches are the fastest growing and most prevalent, adversely impacting organizations’ reputations and incurring financial consequences.
The importance of keeping a watchful eye on the misuse of user access cannot be overstated given its prevalence in real-world attacks. In the current cybersecurity landscape, security measures like multi-factor authentication are no longer enough to deter attackers.
SaaS platforms like Office 365 are a safe haven for attacker lateral movement, making it paramount to focus on user access to accounts and services. When security teams have solid information and expectations about SaaS platforms such as Office 365, malicious behaviors and privilege abuse are much easier to quickly identify and mitigate.
