Auditors have the task of making sure that they do IT network audits to ensure it remains safe from attack and unauthorized access. Security has to be ensured to maintain access. When they are carrying out their duties, they have certain things that they absolutely have to get right.
They have to determine the extent of networks. They do this using what is known as a network diagram. It maps out its extent and the routes within it. For them to be successful, the diagrams should be as accurate as possible. Unfortunately, this is hardly ever the case. As networks are built, they are frequently changed to suit the size of the firm.
The main assets within networks must also be established. This involves finding the right services, systems and assets and working with them to make the system right. When the most vulnerable elements are identified, they can be secured appropriately. The most sensitive parts are usually ERPs, mail servers and other applications.
Establishing the persons with access is also vital. Different parties in all networks have different access to different services. Customers and vendors have some level of access, employees have another level and administrators have their own. It is important to find the respective levels of access in order to point out where a security problem might arise from.
Another key element is to find if there are any connections to external networks. This could be done when looking at the diagram in the initial step. However, dealing with this separately is vital because any compromise could result in catastrophic security errors. In most cases, the main external connection is to the internet.
They also have to find out what the protection mechanisms are. All these add up to ensuring that IT network audits are effective. Security glitches often cost the business even millions of dollars, so no compromise can be taken.
