Data theft is a growing phenomenon primarily caused by system administrators and office workers with access to technology such as database servers, desktop computers and a growing list of hand-held devices capable of storing digital information, such as USB flash drives, iPods and even digital cameras. Since employees often spend a considerable amount of time developing contacts and confidential and copyrighted information for the company they work for, they may feel they have some right to the information and are inclined to copy and/or delete part of it when they leave the company, or misuse it while they are still in employment. They can be sold and bought and then used by criminals and criminal organizations. Alternatively, an employee may choose to deliberately abuse trusted access to information for the purpose of exposing misconduct by the employer; From the perspective of the society such an act of whistleblowing can be seen as positive and is in certain situations protected by law in some jurisdictions, such as the USA.

Filesystem view separation for data confidentiality and integrity using lattice-based security domains
ActiveUS20200004977A1Curtails data theftWithout incurring significant performance overheadDigital data protectionInternal/peripheral component protectionData integrityFile system
A stackable filesystem architecture that curtails data theft and ensures file integrity protection. In this architecture, processes are grouped into ranked filesystem views, or “security domains.” Preferably, an order theory algorithm is utilized to determine a proper domain in which an application is run. In particular, a root domain provides a single view of the filesystem enabling transparent filesystem operations. Each security domain transparently creates multiple levels of stacking to protect the base filesystem, and to monitor file accesses without incurring significant performance overhead. By combining its layered architecture with view separation via security domains, the filesystem maintains data integrity and confidentiality.

Method and device for detecting a suspicious process by analyzing data flow characteristics of a computing device
InactiveUS20180075240A1Accurate detectionDigital data protectionPlatform integrity maintainanceData streamData source
Disclosed are methods and devices for detecting a suspicious process. Test values of data flow direction characteristics of a to-be-detected host and sample values of the data flow direction characteristics corresponding to the to-be-detected host in a data flow direction library are acquired, wherein the data flow direction characteristics comprise at least one of a process list and a network egress characteristic, and a data source characteristic. It is then determined that a suspicious process is detected when a test value of the process list is different from a sample value of the process list and / or a test value of the network egress characteristic is different from a sample value of the network egress characteristic in the case that a test value of the data source characteristic is the same as a sample value of the data source characteristic. It can be seen that the disclosed methods and devices for detecting a suspicious process according detect a suspicious process based on the data flow direction characteristics rather than the attack behaviors of applications. Moreover, because data flow direction characteristics change whenever data theft occurs, the methods and devices can accurately detect a suspicious process in which data might be stolen.
