download at least one hot patch index from the patch server at predefined intervals of time;

identify a set of applicable patches in the patch server; and,

notify the user about the set of applicable patches.

6 . The system of claim 1 , wherein each computer system device in the cluster of computer system device is at least one of a laptop, a server, a local area network, a personal computer, and a smart phone, or any combination thereof.

7 . The system of claim 1 , wherein the cluster of computer system devices use one of Trivial File Transfer Protocol (TFTP), and Dynamic Host Configuration Protocol (DHCP) to communicate with each other.

8 . The system of claim 1 , wherein the at least one memory device and the plurality of processors host a Pre-Boot Execution Environment.

9 . The system for claim 1 , further comprising a scanning module, configured to scan the at least one patch bundle for hot patch scripts and boot file scripts.

10 . The system for claim 1 , wherein the patching module builds a patch boot archive.

11 . A method of patching software in a target computer system device, the method comprising:

storing in at least one memory device, comprised in one or more computer system devices of a cluster of computer system devices, a set of program modules;

receiving by at least one processor, via an input module, an instruction to copy at least one patch bundle into the at least one memory device, wherein the at least one patch bundle comprises boot file scripts, hot patch scripts, a hot patch index, and conditions for implementation of the hot patch scripts, and the boot file scripts;

extracting by the at least one processor via a data transfer module, at least one of the hot patch scripts, the hot patch index, and the boot file scripts from the at least one patch bundle from a patch server;

copying by the at least one processor via the data transfer module, at least one of the hot patch scripts, the hot patch index and the boot file scripts into the designated data staging area, there by staging the at least one of hot patch scripts and boot file scripts;

appending by the at least one processor via the data transfer module, the conditions for implementation of the hot patch scripts and the boot file scripts into at least one staging index;

implementing by the at least one processor via a patching module, the hot patch scripts and the boot file scripts on the target computer system device; and

recording by the at least one processor, via the patching module, information regarding of implementation of the hot patch scripts and the boot file scripts, wherein the information is recorded in the hot patch index.

12 . The method of claim 11 , wherein the at least one memory device further comprises a plurality of trusted patch signatures and patch certificates.

13 . The method of claim 12 , wherein the at least one patch bundle further comprises at least one patch certificate, at least one patch signatures, and information associated with applicability of the boot file scripts and the hot patch scripts.

14 . The method of claim 13 , further comprising the steps of:

extracting by the at least one processor via an authentication module, the at least one patch signature and the at least one patch certificate from the at least one patch bundle;

comparing by the at least one processor via the authentication module, the at least one patch signature and at least one patch certificate with each of the plurality of trusted patch signatures and patch certificates; and,
