Data security software guards digital data from unauthorised access, theft, or manipulation. It includes multiple tools and technologies, including encryption, monitoring and logging and data security. It also includes policies and procedures, as well as tools to deal with data breaches.

Cybercriminals are a single risk factor that can affect security of data, but human error is the leading cause of security breaches. Data security tools come with features that identify mistakes such as putting sensitive files on this page why is important to use virtual data rooms for enterprise value estimation shared drives, or opening emails with the wrong attachments.

Limiting physical access to storage devices and servers is another crucial aspect of data security. Physical security measures can be as simple as requiring employees to sign in each time they enter a building, but they should also include labeling and securing equipment to ensure only authorized personnel are able to access it. This is particularly important when it comes to cloud-based data centers where the physical space could be out of your control.

Data security solutions can protect information in transit and at rest by encrypting the data to ensure that only those who have the right key can read it. This is usually a complement tool to firewalls, intrusion detection or prevention systems (IDS/IPS), and network-based authentication systems.

Another aspect of data security is user behavior analytics. This feature establishes norms of normal activity and identifies irregularities that could suggest unauthorized access to sensitive information. This is usually utilized in solutions that track relational databases, data warehouses and big data solutions.
