Software for protecting data security shields information from unauthorized access manipulation or theft. It includes multiple tools and technologies, including encryption, logging, monitoring and data loss prevention. It also includes policies, procedures, and tools for dealing hacks or data breaches.

Cybercriminals are not the only threat that affects security of data, but human error remains the most frequent cause of security breaches. This is why tools for protecting data contain features that can identify possible mistakes, like placing sensitive files on shared drives or opening wrong email attachments.

Another crucial aspect of data security is restricting physical access to servers, storage devices, and other equipment. Physical measures can be as simple as requiring employees log in each time they enter a building, but they should also include labeling and locking hardware to ensure only authorized personnel are able to access it. This is especially important in cloud-based data centers in which you may not be able to control the physical space.

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

One security measure that is often ignored is user behavior analytics. This sets baselines for normal activities and identifies anomalies that could indicate unauthorised access. This feature is commonly found in solutions to monitor databases that are relational, data warehousing and big data.
