At the time when data theft is rampant in the cyber world, it’s necessary to stem the growing uneasiness among users about the security and protection of their personal data. The reason for this breach is the password thefts. Once a hacker gets hold of a password, it can be used to access any of the victims online accounts, resulting in privacy and security being compromised.

RISK-BASED AUTHENTICATION

2. Risk-based Authentication in Cloud:
At the time when data theft is rampant in the cyber world, it’s necessary to stem
the growing uneasiness among users about the security and protection of their
personal data. The reason for this breach is the password thefts. Once a hacker
gets hold of a password, it can be used to access any of the victims online
accounts, resulting in privacy and security being compromised.
One way to overcome this security breach is to have a strong risk based
authentication process in place. Also known as multi factor authentication, it is
an access control method that adds layers of identity verification to ensure only
authorized users gain network access.
Is Risk Based Authentication the answer?
It might seem that password based authentication is dead. But, the emerging
trend is providing Multifactor authentication along with the password
protection. This move is justified since the businesses have moved to the cloud.
The flexible, scalable and highly available nature of the Cloud is a pain point for
maintaining Identity and Access Management. Risk Based authentication
provides an additional level of authentication for your cloud applications. It is a
dynamic method of applying levels of protection to the system, based on various
factors.
It is a multi-step procedure to prevent any unauthorized access to sensitive data.
It requires multiple pieces of information such as passwords, hardware
credentials or software tokens, to be validated together, before a successful
attempt.
How does risk-based authentication work?
Usually risk based authentication determines a risk score for a login attempt,
based on a user’s behaviour including but not limited to location, previous
activity, device used etc. It triggers an action based on the risk threshold limit
which is set for a system. The more sensitive the system’s data is, the lower is
the threshold limit.

3. It takes into account the risk profiles to determine whether the requesting
access to the system is a valid one or not. As the level of risk increases, the
authentication process becomes more comprehensive and restrictive.
The risk based authentication uses elements such as location based, role
based, activity based and changes in the usual usage patterns:
 Role-based: Depending on who is accessing the account, they must pass
a more stringent authentication content. Different levels of
authentication is required for different users, such as a network
administrator or for a regular user.
 Location-based: Either by detecting the physical endpoint or specific
geographic location. For example, if the user logged in ten minutes ago
from a particular location, and is now trying to log in from another
location which is practically impossible for him to be present, then it’s
definitely considered a high-risk transaction. Other attributes can figure
into the overall risk score, too.
 IP Address-based: The IP address of the physical device or the end point
of the connection is used to verify.
 Activity-based: For example, large-value account transfers have a higher
risk associated than just a balance inquiry.
 Changes in usual transaction patterns: If a user is doing something that
doesn’t match his or her purchase history, then that becomes a riskier

requests and logins.
Importance of risk based authentication
Risk-based authentication helps judge whether users are actually who they say
they are, determines the correct (or minimum) credential requirements and
works with a range of credentials.
Adaptive or risk-based authentication allows you to evaluate a set of
contextual factors related to access attempts or transactions to better
estimate the risk involved, without impacting the experience for legitimate
users. As a robust, multi-channel risk assessment and fraud detection solution,
it transparently helps you detect and prevent fraud. It also helps you with
maintaining your organization’s internal and external compliance
requirements, including FFIEC, HIPAA, PCI and SOX.
Before implementing a risk based authentication for your cloud network or
website, a correct risk assessment should be performed by the administrator
taking into account the following factors:
 The size of the system, in terms of the number of users. As a system
grows larger, the chance of a breach increases.
 The extent to which the system is critical to maintaining the operation of
the organization. The most critical systems carry the greatest risk of
serious damage in the event of a breach.
 The ease with which data can be compromised or the system cracked by
someone with the means and intent to do so. In spite of budget
constraints, the protective measures such as firewalls and antivirus
software should be robust and up-to-date
 Sensitive vital customer information such as names, addresses, numbers,
and Social Security numbers requires enhanced protection.
