Abstract: Various methods and systems for monitoring files in a computer system are provided. In this regard, aspects of the invention facilitate file monitoring without file handle use, as it pertains to file monitoring and tailing, thereby mitigating file handle locking conflicts. In various implementations, information for the monitored files is obtained from the kernel using a filter driver in the I/O path. When the filter driver detects write operations being performed on monitored files, file-write data is copied and placed in a kernel buffer, where it can be pulled by a user mode monitoring process and fed to a monitoring application. As such, there is no need for coordination between the monitoring process and the user mode processes of other third-party applications writing data to monitored files.

Abstract: A computer system, such as a data storage system, implements techniques for segregating and controlling access to data stored in multiple regions. In some embodiments, redundancy coded shards generated from the data and stored in durable storage of a data storage system is allocated across multiple regions, but in a fashion that prevents actors with access to regions outside that of a “home” region from recovering a sufficient number of unique shards to regenerate the data represented thereby. In some embodiments, encryption is used to segregate the data by encrypting the generated shards, then storing the cryptographic information on or otherwise controlling access on hosts or other devices of only the home region.

Abstract: An approach is disclosed for implementing failover and resume when using ordered sequences in a multi-instance database environment. The approach commences by instantiating a first database instance initially to serve as an active instance, then instantiating a second database instance to serve as an instance of one or more passive instances. The active database establishes mastership over a sequence and then processes requests for the ‘next’ symbol by accessing a shared sequence cache only after accessing a first instance semaphore. The active instance and the passive instance perform a protocol such that upon passive database detection of a failure of the active database, one of the passive database instances takes over mastership of the sequence cache, and then proceeds to satisfy sequence value requests. The particular order is observed in spite of the failure.

Abstract: A hardware-assisted technique may protect a system log from attackers, regardless of an attacker's acquired privileges at the host system. In some embodiments, the technique may employ specialized hardware, e.g., in the form of an add-on peripheral card. The hardware may be connected to a commodity server through a standard bus. Said hardware may stores log files from a host system while permitting only read and append operations from the host system. Thus, even if the attacker obtains root privileges at the host system, removal through the host system of logs may be prevented because the asymmetric interface does not support such commands from the host system. In some embodiments, an existing log file storage path at the host system may be maintained, reducing the required change to implement the disclosed techniques within existing server setups. Further, any performance degradation due to the techniques may be small to negligible.

Abstract: A method to reduce delays associated with restoring quarantined files is disclosed. In one embodiment, such a method includes maintaining, for a file, a “current” pointer pointing to a current copy of the file and a “backup” pointer pointing to a virus-free backup copy of the file. The method receives an I/O request (a read or write request) to access the file. In response to receiving the I/O request, the method scans the current copy of the file for viruses. In the event a virus is discovered in the current copy, the method modifies the “current” pointer to point to the backup copy. This causes the backup copy to become the new current copy. The method then executes the I/O request with respect to the new current copy. A corresponding system and computer program product are also disclosed and claimed herein.
