A cloud-based file integrity monitoring service identifies content changes to a computer file. An endpoint cybersecurity agent monitors its host client device for read / write and other operating system events associated with the computer file. When the endpoint cybersecurity agent detects each operating system event, the endpoint cybersecurity agent captures and reports, in real time or near real time, a snapshot of the file content representing the computer file. So, as the host client device changes the computer file with each operating system event, the endpoint cybersecurity agent uploads timestamped snapshots of the file content to a cloud-based file integrity monitoring service. The cloud-based file integrity monitoring service stores each snapshot of the file content, thus logging a change history for the computer file. The cloud-based file integrity monitoring service may thus retrieve and analyze different snapshots at different points in time, thus quickly identifying the content changes to the computer file.

Visual representations represented in computer files can undergo various changes, in terms of specific visual details in a visual representation, without changing the semantics of what is represented. The present disclosure provides techniques and solutions for generating an identifier for a visual representation using one or more content-independent semantic metadata elements. Content-independent semantic properties are those that do not correspond to individual visual elements in a visual representation, or to properties of a visual representation that do not contribute to a description of an overall semantic provided by the visual representation. Disclosed techniques can be used to identify when a visual representation is generated or imported that has the same overall semantic, as indicated by the identifier, as another visual representation. The two visual representations can have the same or different image elements. Disclosed techniques also provide that visual representations that have a different overall semantic are assigned different identifiers.

A deterministic finite automata (DFA) is used by an extended Berkley packet filter (or “eBPF”) to monitor file system operations and non-file system operations. The DFA is stored as an eBPF map. Before a kernel of an operating system executes any file system operation, the kernel runs an eBPF program that queries the DFA for a filename associated with the system operation. The DFA represents safe / suspicious filenames associated with computer files. If the filename matches the DFA, then the kernel notifies a cybersecurity agent. The cybersecurity agent may then block or allow the file system operation, depending on whether the filename is safe or suspicious. The DFA stored in the extended BPF thus greatly improves computer functioning by very quickly and simply identifying safe / suspicious operations.
