HOW WILL LEAST PRIVILEGE PROTECT MY BUSINESS?

 

Least privilege is defined as giving a user only those privileges that are essential to perform his/her intended

function. All companies, regardless of how large or small they are, must manage the access employees

have to corporate assets. It’s very easy for small companies to fall into the trap of thinking that they can just

give everyone access to everything. It’s quick, easy, and requires no maintenance as people fulfill changing

roles within the company. However, it’s a security risk because people can then perform tasks that they were

not intended to perform or can access data that they were not intended to see.

 

Part of a company’s cybersecurity approach includes limiting access based on each employee’s job function.

For example, Kevin is a human resources manager and Beth is a system developer. Kevin will need access to

employee records and the Personally Identifiable Information (PII) that is associated with those records. Beth

will need access to developer toolkits and source code. As a human resource manager, Kevin will never need

access to developer toolkits and source code; likewise, Beth’s role as a system developer will never require

her to access human resource records.

 

FACT 1: LIMITING EXPOSURE

Least privilege helps companies reduce insider threats, maintain confidentiality, and increase their overall security

posture. Without least privilege, Beth would have access to human resource records and could view the
sensitive records of every employee. If Beth had any bad intentions, she could use that information to steal other
employee’s identities. In turn, if Kevin has access to system development tools and source code, he could add a

virus to the system or take the code to a competitor. Least privilege eliminates both of these situations by not giving
employees access to systems and data that they don’t need.

 

 

DID YOU KNOW…

  • Everyone in the organization doesnt need access to everything.
  • Create defined roles based on job functions and assign access to systems and data based on the job the

employee performs.

  • Review access permissions on a regular basis.
  • Insider threat is defined as someone within the organization that has access to systems and data that could harm

the organization either intentionally or unintentionally. Limiting access through least privilege helps protect your

company from this type of threat.
