Protecting against and learning attack vectors on web artifacts

1. A system comprising: a processor; and memory configured to store one or more sequences of instructions which, when executed by the processor, cause the processor to carry out the steps of protecting against attacks to web files hosted on a web server by:

performing a plurality of monitoring tasks by a service processor, the service processor being hosted by a baseboard management controller (BMC) and independent of a central processing unit (CPU) of the web server, the plurality of monitoring tasks comprising:

receiving a plurality of packets forming access requests made to the web files;

determining that a packet is suspicious when a source Internet Protocol (IP) address associated with the packet is not on a whitelist or a blacklist;

updating a learning block with information about each suspicious packet, the information comprising a signature associated with the suspicious packet, a source IP address associated with the suspicious packet, and a time indicating when the suspicious packet arrived;

updating a counter indicating a number of times a packet with the signature of the suspicious packet was received;

forwarding the suspicious packet to the web server when the counter is below a threshold;

not forwarding the suspicious packet to the web server when the counter is above the threshold; and

upon not forwarding the suspicious packet, analyzing the suspicious packet in conjunction with other packets previously determined to be suspicious, the analyzing comprising:

rearranging an order in which the suspicious packet and the other suspicious packets arrived to form a new arrival sequence of the suspicious packets;

matching the new arrival sequence of the suspicious packets to attack patterns stored in an attack pattern database; and

upon the new arrival sequence of the suspicious packets matching an attack pattern, adding source IP addresses associated with the suspicious packets matching the attack pattern to the blacklist.

2. The system of claim 1 wherein the plurality of monitoring tasks comprise periodically checking the web files for changes indicating the web files have been compromised.

3. The system of claim 1 wherein the plurality of monitoring tasks comprise:

requesting, by the service processor at a first time, that the web files be copied to a shared storage accessible by the service processor and host CPU to create a first copy;

requesting, by the service processor at a second time, after the first time, that the web files be copied to the shared storage to create a second copy;

comparing the second copy against the first copy to detect any changes indicated the web files were compromised; and

generating an alert notification upon detecting the changes.

4. The system of claim 1 wherein the plurality of monitoring tasks comprise:

requesting, by the service processor, that logs associated with the web files be copied to a shared storage accessible by the service processor and host CPU, the logs comprising entries storing access requests made to the web files;

comparing the access requests against a database of attack patterns; and

generating an alert notification upon detecting that an access request matches an attack pattern.

5. The system of claim 1 wherein the service processor is powered independent of the host CPU.

6. The system of claim 1 wherein the service processor and host CPU reside in a same single box.

7. A method for protecting against attacks to web files hosted on a web server comprising:

performing a plurality of monitoring tasks by a service processor, the service processor being hosted by a baseboard management controller (BMC) and independent of a central processing unit (CPU) of the web server, the plurality of monitoring tasks comprising:

receiving a plurality of packets forming access requests made to the web files;

determining that a packet is suspicious when a source Internet Protocol (IP) address associated with the packet is not on a whitelist or a blacklist;

updating a learning block with information about each suspicious packet, the information comprising a signature associated with the suspicious packet, a source IP address associated with the suspicious packet, and a time indicating when the suspicious packet arrived;

updating a counter indicating a number of times a packet with the signature of the suspicious packet was received;

forwarding the suspicious packet to the web server when the counter is below a threshold;

not forwarding the suspicious packet to the web server when the counter is above the threshold; and

upon not forwarding the suspicious packet, analyzing the suspicious packet in conjunction with other packets previously determined to be suspicious, the analyzing comprising:

rearranging an order in which the suspicious packet and the other suspicious packets arrived to form a new arrival sequence of the suspicious packets;

matching the new arrival sequence of the suspicious packets to attack patterns stored in an attack pattern database; and

upon the new arrival sequence of the suspicious packets matching an attack pattern, adding source IP addresses associated with the suspicious packets matching the attack pattern to the blacklist.

8. The method of claim 7 wherein the plurality of monitoring tasks comprise periodically checking the web files for changes indicating the web files have been compromised.

9. The method of claim 7 wherein the plurality of monitoring tasks comprise:

requesting, by the service processor at a first time, that the web files be copied to a shared storage accessible by the service processor and host CPU to create a first copy;

requesting, by the service processor at a second time, after the first time, that the web files be copied to the shared storage to create a second copy;

comparing the second copy against the first copy to detect any changes indicated the web files were compromised; and

generating an alert notification upon detecting the changes.

10. The method of claim 7 wherein the plurality of monitoring tasks comprise:

requesting, by the service processor, that logs associated with the web files be copied to a shared storage accessible by the service processor and host CPU, the logs comprising entries storing access requests made to the web files;

comparing the access requests against a database of attack patterns; and

generating an alert notification upon detecting that an access request matches an attack pattern.

11. The method of claim 7 wherein the service processor is powered independent of the host CPU.

12. The method of claim 7 wherein the service processor and host CPU reside in a same single box.

13. A computer program product, comprising a non-transitory computer-readable medium having a computer-readable program code embodied therein, the computer-readable program code adapted to be executed by one or more processors to implement a method comprising:

performing a plurality of monitoring tasks by a service processor, the service processor being hosted by a baseboard management controller (BMC) and independent of a central processing unit (CPU) of the web server, the plurality of monitoring tasks comprising:

receiving a plurality of packets forming access requests made to the web files;

determining that a packet is suspicious when a source Internet Protocol (IP) address associated with the packet is not on a whitelist or a blacklist;

updating a learning block with information about each suspicious packet, the information comprising a signature associated with the suspicious packet, a source IP address associated with the suspicious packet, and a time indicating when the suspicious packet arrived;

updating a counter indicating a number of times a packet with the signature of the suspicious packet was received;

forwarding the suspicious packet to the web server when the counter is below a threshold;

not forwarding the suspicious packet to the web server when the counter is above the threshold; and

upon not forwarding the suspicious packet, analyzing the suspicious packet in conjunction with other packets previously determined to be suspicious, the analyzing comprising:

rearranging an order in which the suspicious packet and the other suspicious packets arrived to form a new arrival sequence of the suspicious packets;
