Software object corruption detection

The execution of a software application is diverted to detect software object corruption in the software application. Software objects used by the software application are identified and their pointers are inspected. One or more tests are applied to pointers pointing to the virtual method tables of the software objects, addresses (or pointers) in the virtual method tables, and memory attributes or content of the memory buffer identified by the addresses for inconsistencies that indicate corruption. A determination of whether the software objects are corrupted is made based on the outcome of the tests. If software object corruption is detected, proper corrective actions are applied to prevent malicious exploitation of the corruption.

Replication systems and methods for a virtual computing environment

Hybrid replication systems and methods for a virtual computing environment utilize snapshot rotation and differential replication. During snapshot rotation, data modifications intended for a source virtual machine disk (VMDK) are captured by a primary snapshot. Once a particular criterion is satisfied, the data modifications are redirected to a secondary snapshot while the primary snapshot is committed to both source and target VMDKs. The secondary snapshot is then promoted to primary, and a new secondary snapshot is created with writes redirected thereto. If the VMDKs become out-of-sync, disclosed systems can automatically perform a differential scan of the source data and send only the required changes to the target server. Once the two data sets are synchronized, snapshot replication can begin at the previously configured intervals. Certain systems further provide for planned failover copy operations and / or account for migration of a virtual machine during the copying of multiple VMDKs.

Compression method for relational tables based on combined column and row coding

A robust method to compress relations close to their entropy while still allowing efficient queries. Column values are encoded into variable length codes to exploit skew in their frequencies. The codes in each tuple are concatenated and the resulting tuplecodes are sorted and delta-coded to exploit the lack of ordering in a relation. Correlation is exploited either by co-coding correlated columns, or by using a sort order that can leverage the correlation. Also presented is a novel Huffman coding scheme, called segregated coding, that preserves maximum compression while allowing range and equality predicates on the compressed data, without even accessing the full dictionary. Delta coding is exploited to speed up queries, by reusing computations performed on nearly identical records.

Exploit detection system with threat-aware microvisor

An exploit detection system deploys a threat-aware microvisor to facilitate real-time security analysis, including exploit detection and threat intelligence, of an operating system process executing on a node of a network environment. The microvisor may be organized as a main protection domain representative of the operating system process. In response to the process attempting to access a kernel resource for which it does not have permission, a capability violation may be generated at the main protection domain of the microvisor and a micro-virtual machine (VM) may be spawned as a container configured to encapsulate the process. The main protection domain may then be cloned to create a cloned protection domain that is representative of the process and that is bound to the spawned micro-VM. Capabilities of the cloned protection domain may be configured to be more restricted than the capabilities of the main protection domain with respect to access to the kernel resource. The restricted capabilities may be configured to generate more capability violations than those generated by the capabilities of the main protection domain and, in turn, enable further monitoring of the process as it attempts to access the kernel resource.

Pre-storage of data to pre-cached system memory

System(s) and method(s) that facilitate utilizing pre-cached disk space. Pre-cached memory space within a storage device is identified, and a subset of the pre-cached memory space is pre-populated with data so that the data can be selectively and dynamically accessed. During use of a computer (e.g., in a web-browsing session) a subset of the pre-stored data can be dynamically and selectively exposed to the user as a function of user and / or computer application state. Pre-storage of the data on pre-cached memory of the computer mitigates delayed data access (e.g., due to insufficient transmission bandwidth) thereby enhancing user computing experience. The user can utilize the device without having to distinguish between pre-cached and free memory. In other words, the operating system can present the cached memory to the user so that it appears as free memory without the user having to direct the system to do so.
