The information systems help in decisions making, support, managing of the people and projects in a department (Dhillon& Backhouse, 2000). To tonsure the security of the users in the information systems, several measures have to be taken; this is to avoid any inconveniences in the running of the organization.

Security is ensured to the users when the organization makes regular changes to their management information systems. This is done through the successful implementation of updated and new software and hardware components. These continuous changes bring about better adjustment done to configure the information systems. Also, the frequent make cakes users aware of the emerging security threats and they, therefore, adapt to the emerging situation. In most organizations, they have to develop their information systems, in so doing so, they have to employ several components, these components are different and can be interconnected in their specified arrangements in that they can encounter the organization’s mission, business their security needs (Dhillon& Backhouse, 2000).  To ensure that there is security in information, there are various techniques that have to be implemented for the management, operation, and security in conformation. These techniques go hand in a hand with several mainframes which include, servers, applications, operating systems, and workstations (Dhillon& Backhouse, 2000).

Maintaining information with a level of confidentiality, availability, and integrity is of many benefits to the users. To ensure security in information, the security systems have to control its access panel. The major role of access is to prevent unauthorized login from unknown users in that they will not adjust or use their information. Access is grouped into three categories; preventive, corrective, and detective. These three categories have their roles, preventive control role is the elimination of occurrence of a disastrous event; detective controls harmful events while corrective controls and restores systems due to harmful events (Dhillon& Backhouse, 2000). They access so much such that a user with an unidentifiable identification can access several department information. If such an event occurs, the organization is prone to exposures, threats, and risks.

Computers are managed by many individuals in the world. They can be used as part of a department, in groups, or by the user in the universe. All of these computers and their categorization must be accessed by an IP address or the MAC address. The internet protocol principle of working is to connect several computers to a known network, this enables sharing and transfer of data to the computers linked. For a user to access a network, the internet protocol number must be known. This number is unique and is usually assigned to every computer.  Few organizations use their computers globally (Dhillon& Backhouse, 2000). They involve the use of a collection of many computers in specific sites then they share the same task assigned. Some of the servers are used and each must have its internet protocol number for users to share information from the data. The internet protocol is a number that must only be confidential to its users; this is to ensure that the accounts are not being hacked by unknown identities.

Security for users in the information systems is well taken care of if there is cooperation and mutual understanding between the users and the managers. Successful organizations keenly work on their confidentiality and security of information by putting in place several panels of information systems (Dhillon& Backhouse, 2000). A management information system is of great importance in the current world due to the rise of the number of threats and their frequent use.
