Today, companies are spending millions of dollars on cybersecurity, but compromised systems and stealing sensitive information are still huge problems. Protecting sensitive information has always been of vital importance. However, the struggle today is that digital information can be distributed to an endless amount of users, everywhere in the world. Security solutions today focus on role-based access control and "the principle of the least privilege". They can affect the productivity of employees, which is also a key aspect to be considered when it comes to security. Privilege users are the ones that possess the most permissions within a system and are, therefore, a significant risk. This thesis project is focusing on developing a solution that protects against security risks connected to the users with the most privilege. The developed solution resulted in a modular role-based access methodology, also adding the "four-eye principle" (4EP). By introducing an extra shield outside the standard API, sensitive commands sent unwittingly or wittingly by a privileged user can be discovered before compromising a system or leaking sensitive information. Introducing the "four-eye principle" in a secure proxy solution, a "third-party" user approves sensitive commands before reaching the intended system. The solution is developed in JAVA and is adaptable to different organisations by letting the system administrators choose an intended system, which policies of sensitive commands to apply and whom that needs to approve them. The concepts implemented in this prototype can be used in future industrial developments. |
