In the physical world, as a society, we have surmounted this problem already.

Application in general business and in accounting

If the hackers are able to steal the credentials of one of these powerful team members, they could take full advantage of their newfound access, doing significant damage to the network and stealing significant amounts of sensitive data. Without an SoD plan in place, members of the security team may have access to the network without any checks and balances from other team members. Within an SoD plan, at least two team members should always have oversight of the system.

End users cannot access or modify production data, except through an appropriate administrative application. Software developers, contractors, and third-party vendors cannot access production systems, database management systems, or system-level technologies.

Using IT Security Controls to Implement Separation of Duties

In the rest of this post, we explore how a small business can approach separation of duties.

NIST FIPS validation is an important certification to look for in an encryption key manager.

Common areas for Separation of Duties in IT Organizations include:

Create two user accounts for Administrators and DBAs—one for routine activities such as email and one for activities requiring privileged user access and permissions. Implement separation of duties controls, based on the results of step 3. Implementation should use the principle of least privilege necessary to complete a transaction. The individual responsible for designing and implementing security can’t be the same person as the person responsible for testing security, conducting security audits, or monitoring and reporting on security. Therefore, the individual responsible for information security should not report to the chief information officer. Companies in all sizes understand the importance of not combining roles such as receiving checks , approving write-offs, depositing cash and reconciling bank statements, approving time cards, and having custody of paychecks.
