Controlling Access to Information

Information should be controlled if it is sensitive and not in the public domain. Public information can be accessed by anyone but for organizations that have created their own information, not everyone can get to it. The challenge in modern information systems is being able to control who gets to access information and who gets locked out of the information system. This is a simple way of getting a hold on who is trying to access information and locking them out until they provide an authentication that is genuine. The authentication is a means of proving who the user is and controls how much access they are able to have over the information. Administrators get to have complete control over the application and the information they access while normal uses will only get to see what they are authorized to depending on their access level.

Usernames and passwords are one of the ways to ensure that anyone that is getting into an information system is an actual user of the system and has been authorized to make changes to the information. The access levels are also controlled and users that are not authorized to modify information will get a read-only version of the information. Information usage can also be controlled using two-factor authentication in case the physical presence of the user has to be confirmed. This prevents programs and automated systems from logging into an application as they will be required to swipe a card or scan a QR code after they have entered the password in order to be let into a system. Managing the access to information makes it possible to have better control over how it is used and modified. Designers of information systems always put in place controls to prevent sneaky users from getting into the system which then ensures that the information is always safe.

Whenever a user has logged into a system, they are noted down and logged into the system records. This makes it possible to uproot the bad users that are always insistent on getting into these systems and not using the systems in the correct manner. If there are bad users of any system, their access patterns are noted and they get to be locked out and their access mechanisms revoked. The access to information has to be really controlled as there is no other way that it can be kept safe and secure from harm by reckless users and hackers. With the control to access, the power remains with the system to determine who can access the information and who gets locked out.

In conclusion, information systems are designed with safeguards in mind, similar to what device users enforce on their lock screens to prevent other users from opening their information when they are not around. Authentication of users and verification of their credentials makes it possible to lock out the unverified users and revoke the credentials that are used for bad reasons on the system. This maintains the integrity of a system and makes the information more reliable.
