4 DataSecurity Measures You Can't Do Without

Firewall
Firewalls are pieces of software which control access to information on either side of a data point. They can be set to higher or lower threat levels, but essentially a firewall works by blocking any ports which could be used for access except for a very few.
Firewalls are used to ensure that any software and hardware used by a business is as safe as it can be from malware and outside attacks.

Private networks
A private network is a network which is restricted to certain people or servers. There are two kinds of network: one which is physical, and one which is virtual.
A physical network is one which exists between pieces of hardware – most often the existing computers which the employees of a business work on. The network allows them to share information and store data, eliminating the need for physical storage, and making the job of the employees easier. A virtual private network is almost the same as a physical network, except it acts to connect hardware in remote locations. This functions in almost the same way as a physical network, except that the network does not connect hardware which is in the same building, but much further afield.
 
Utilizing private instead of public networking for internal communication is almost always preferable given the choice between the two. However, since other users within the data centre are able to access the same network, you still must implement additional measures to secure communication between your servers.
When it comes to data security, using a private network is far superior to using a public one because of the security issues. Private networks are not infallible, but they are much more difficult to access than are public ones, and the information is not on display.

File auditing
File auditing refers to a process of taking the current file and comparing it with a record or version of the file from an older time period, as a means of seeing whether it has been changed in the time between the two file versions. Further auditing also includes the ability to see who made the changes, and whether or not they were authorised. This is an important step in security for businesses, as it allows them a greater degree of control over their files and other information.
Service auditing
While the first three security measures discussed in this article have involved virtual methods to increase data security, this final point is for a physical method of increasing data security (for more methods, go here). Service auditing refers to the systems themselves, the hardware as well as the software, and how they can be secured.
Service auditing refers to the process of truly understanding your own hardware and systems, to the point where you know the individual components, and can gain a sense of what it looks like when it is working well, so as to understand what it looks like when it is not working. Data security depends on knowing your systems to this extent, and knowing which servers power which parts of infrastructure, and so on.
