According to an example, an intrusion-prevention system may include a network interface to receive a subject data word via a network. The intrusion-prevention system may include hardware to determine whether the subject data word partially matches a signature data pattern, and determine whether the subject data word fully matches the signature data pattern if the subject data word partially matches the signature data pattern. 160-. (canceled)61. An intrusion-prevention system (IPS) comprising:a network interface to receive a subject data word via a network; and determine whether the subject data word partially matches a signature data pattern,', 'determine the subject data word is not a match of the signature data pattern if the subject data word does not partially match the signature data pattern, and', 'determine whether the subject data word fully matches the signature data pattern if the subject data word partially matches the signature data pattern., 'hardware to'}62. The IPS of claim 61 , wherein the subject data word includes data blocks and the signature pattern includes data blocks claim 61 , and to determine if the subject data word does not partially match the signature data pattern claim 61 , the hardware is to determine whether a subset of the data blocks less than all the data blocks in the subject data word does not match any corresponding data blocks in the signature data pattern.63. The IPS of claim 62 , wherein to determine whether the subset of the data blocks less than all the data blocks in the subject data word does not match any corresponding data blocks in the signature data pattern claim 62 , the hardware is to determine whether the subset of the data blocks in the subject data word matches data blocks in the signature data pattern with respect to both value and position.64. The IPS of claim 61 , wherein to determine whether the subject data word fully matches the signature data pattern claim 61 , the hardware is to determine whether all of ...
