Which of the following is the GREATEST risk of single sign-on?
Click on the arrows to vote for the correct answer
A. B. C. D.A.
Single sign-on (SSO) is a mechanism that allows users to log in to multiple applications with a single set of credentials. This technology streamlines authentication processes and enhances security by eliminating the need to manage multiple usernames and passwords. However, there are risks associated with the use of SSO.
Out of the options given, the greatest risk of single sign-on is:
A. It is a single point of failure for an enterprise access control process.
This means that if the SSO system fails, users will not be able to access any of the connected applications. The entire access control process will be compromised, and the organization will be exposed to significant risk. Additionally, attackers could exploit any vulnerabilities in the SSO system to gain access to multiple applications with a single set of compromised credentials. This could result in a significant data breach or other security incidents.
B. Password carelessness by one user may render the entire infrastructure vulnerable.
Although password carelessness by one user is a risk, it is not the greatest risk associated with SSO. With proper training and security awareness programs, organizations can reduce the likelihood of this happening.
C. Integration of single sign-on with the rest of the infrastructure is complicated.
While integrating SSO with the rest of the infrastructure can be challenging, it is not the greatest risk associated with SSO. With proper planning and implementation, integration issues can be addressed.
D. One administrator maintains the single sign-on solutions without segregation of duty.
While segregation of duties is a best practice for security, it is not the greatest risk associated with SSO. With proper access controls and oversight, the risk of an administrator abusing their privileges can be minimized.
In summary, the greatest risk associated with SSO is that it is a single point of failure for an enterprise access control process. This risk should be mitigated through redundancy, testing, and appropriate security controls.
