A system located in head office, this system consists of oracle database and oracle forms, there is some users on database are default users and their passwords cannot be changed.<br />
This system is connected to branches; the local network is connected to a firewall which is connected to a router to the branches.<br />
Now some employees on branches knows the password of the default users which has special permissions on database.<br />
The question is : can we let the employees on branches open the oracle forms and connect to database and restrict them to a new user we create for them on DB and disallow them to access the data base using one of the default users using the firewall?<br />
<br />
Thanks,

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals.
