Data security software protects digital data from the risk of unauthorized access, theft or manipulation. It comes with a variety of tools and techniques, such as encryption, monitoring and logging, and data protection. It also includes procedures, policies and tools to deal hacks or data breaches.
Cybercriminals are only one of the many threat to security of data, but human error remains the leading cause of breaches. This is why tools for protecting data include tools that can spot errors that could be made, for example, placing sensitive files on shared drives or opening wrong email attachments.
Limiting physical access to servers and storage devices is another crucial aspect of data protection. 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 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 in control of the physical space.
Data security solutions can protect data in transit and at rest by encrypting data so that only those who have the right key are able to read it. This is typically a complimentary tool for firewalls, intrusion detection or prevention systems (IDS/IPS), and network-based authentication systems.
Another feature that protects data is user behavior analytics. It establishes the baselines for normal activity and identifies irregularities that could suggest the unauthorized access of sensitive information. This feature is commonly used in monitoring solutions for the relational database, data warehousing and big data.
