Security software for data protects digital information from unauthorized access, manipulation, or theft. It includes multiple tools and technologies, including encryption, logging and monitoring, and data protection. It also includes policies and procedures, as well as tools to handle data breaches.
Cybercriminals are a single threat that affects security of data, but human error remains the most frequent cause of breaches. This is the reason why data security tools include 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 storage devices, servers and other equipment. Physical security measures could be the simplest of things like requiring employees to login before entering the building. It is also recommended to include marking and securing equipment to ensure that only authorized personnel have access to it. This is especially critical for cloud-based data centers, where the physical space may be out of your control.
Data security solutions are useful reference top driver able to protect data in transit and at rest by encrypting the data so that only those with the correct keys are able to read it. This is often a supplement tool for firewalls, intrusion detection and prevention systems (IDS/IPS) and networks-based authentication systems.
A data security feature that is often ignored is user behavior analytics. It establishes baselines for normal activities and identifies anomalies which could indicate unauthorized access. This feature is usually found in solutions to monitor data warehouses, relational databases and big data.
