Data security software guards digital data avast driver updater from unauthorised access, theft, or manipulation. It encompasses multiple tools and technologies, such as encryption monitoring, logging and data loss prevention. It also includes procedures, policies and tools to deal with data breaches or hacks.
Cybercriminals are only one of the many threat that affects security of data, however human error is the most common cause of security breaches. Data security tools come with features that identify mistakes, like placing sensitive files on shared drives and opening emails with the wrong attachments.
Another crucial aspect of data security is restricting physical access to storage devices, servers and other equipment. Physical security measures could be such things as requiring employees sign in before entering a building. They should also include marking and securing equipment to ensure that only authorized personnel are able to access it. This is especially critical in a cloud-based data center in which the physical space can be beyond your control.
Data security solutions are able to protect information in transit and at rest by encrypting the information so that only people with the correct keys can read it. This is often a complementary tool to firewalls, intrusion detection and prevention systems (IDS/IPS), and networks-based authentication systems.
One security measure that is often overlooked is user behavior analytics. This establishes baselines for normal activity and detects anomalies that could signal unauthorized access. This is typically found in systems that monitor relational databases, data warehouses, and big data solutions.
