System, method, and computer program product for segmenting a database based, at least in part, on a prevalence associated with known objects included in the database
View Patent ↗A system, method, and computer program product are provided for segmenting a database based, at least in part, on a prevalence associated with known objects included in the database. In operation, a database including a plurality of known objects is identified. Additionally, the database is segmented into a plurality of segments. Furthermore, each of the plurality of known objects are assigned to one of the plurality of segments, based at least in part on a prevalence associated with each of the plurality of known objects.
1. A computer program product embodied on a non-transitory computer readable medium for performing operations, comprising:
identifying a database including a plurality of known objects;
segmenting the database into a plurality of segments; and
assigning each of the plurality of known objects to one of the plurality of segments, based at least in part on a prevalence associated with each of the plurality of known objects, wherein the database includes whitelisted objects, which are non-malicious objects, and which are defined utilizing a Bloom filter of a client system, and wherein the Bloom filter is further configured to determine whether to perform a lookup operation on the database.
2. The computer program product of claim 1 , wherein the computer program product is operable such that the known objects include objects known to be non-malicious.
3. The computer program product of claim 1 , wherein the computer program product is operable such that the database includes a whitelist database.
4. The computer program product of claim 1 , wherein the computer program product is operable such that the prevalence includes one of a high prevalence or a low prevalence.
5. The computer program product of claim 1 , wherein the computer program product is operable such that at least one of the plurality of segments corresponds to low prevalence objects.
6. The computer program product of claim 1 , wherein the computer program product is operable such that at least one of the plurality of segments corresponds to high prevalence objects.
7. The computer program product of claim 1 , wherein the computer program product is operable such that the Bloom filter is utilized as a whitelist to offset a high false positive rate.
8. The computer program product of claim 1 , wherein the computer program product is operable such that a server system updates the Bloom filter stored on the client system.
9. The computer program product of claim 8 , wherein the computer program product is operable such that the updating includes pushing hashes stored as Bloom filter bit vectors to the client system.
10. The computer program product of claim 8 , wherein the computer program product is operable such that Bloom filter updates are sent along with additional software updates.
11. The computer program product of claim 1 , wherein the computer program product is operable such that the Bloom filter is associated with a blacklist.
12. The computer program product of claim 1 , wherein the computer program product is operable such that the plurality of known objects include at least one of files or programs.
13. The computer program product of claim 1 , wherein the computer program product is operable such that prevalence information is obtained utilizing client system based antivirus software.
14. A method to be performed in conjunction with a processor, comprising:
identifying a database including a plurality of known objects;
segmenting the database into a plurality of segments; and
assigning each of the plurality of known objects to one of the plurality of segments, based at least in part on a prevalence associated with each of the plurality of known objects, wherein the database includes whitelisted objects, which are non-malicious objects, and which are defined utilizing a Bloom filter of a client system, and wherein the Bloom filter is further configured to determine whether to perform a lookup operation on the database.
15. An apparatus, comprising:
a processor; and
a memory coupled to the processor, wherein the apparatus is configured for:
identifying a database including a plurality of known objects:
segmenting the database into a plurality of segments; and
assigning each of the plurality of known objects to one of the plurality of segments, based at least in part on a prevalence associated with each of the plurality of known objects, wherein the database includes whitelisted objects, which are non-malicious objects, and which are defined utilizing a Bloom filter of a client system, and wherein the Bloom filter is further configured to determine whether to perform a lookup operation on the database.
