Abstract
Methods and systems for maintaining computer security are provided. The method for maintaining security of a computer system comprises determining an initial system certainty value for the computer system, providing access to a database of signatures, each signature including a signature certainty value, receiving data, comparing the received data with the database of signatures, increasing the system certainty value if the received data does not match a signature in the database, decreasing the system certainty value if the received data matches a signature in the database and filtering the data based on the system certainty value and the signature certainty value of a signature matching the received data.
Claims24
A computer-implemented method for maintaining security of a computer system, the computer comprising a memory and a central processing unit, comprising:
- determining an initial system certainty value for the computer system;
- providing access to a database of signatures, each signature including a signature certainty value;
- receiving data;
- comparing the received data with the database of signatures;
- increasing the system certainty value if the received data does not match a signature in the database;
- decreasing the system certainty value if the received data matches a signature in the database;
- and
- filtering the data based on the system certainty value and the signature certainty value of a signature matching the received data.
A system for maintaining computer security, comprising:
- means for determining an initial system certainty value for the computer system;
- means for providing access to a database of signatures, each signature including a signature certainty value;
- means for receiving data;
- means for comparing the received data with the database of signatures;
- means for increasing the system certainty value if the received data does not match a signature in the database;
- means for decreasing the system certainty value if the received data matches a signature in the database;
- and
- means for filtering the data based on the system certainty value and the signature certainty value of a signature matching the received data.
A computer recording medium including computer executable code for maintaining security of a computer system, comprising:
- code for determining an initial system certainty value for the computer system;
- code for providing access to a database of signatures, each signature including a signature certainty value;
- code for receiving data;
- code for comparing the received data with the database of signatures;
- code for increasing the system certainty value if the received data does not match a signature in the database;
- code for decreasing the system certainty value if the received data matches a signature in the database;
- and
- code for filtering the data based on the system certainty value and the signature certainty value of a signature matching the received data.
A system for maintaining computer security, comprising:
- a computer comprising a memory and a central processing unit, the computer being operable to:
- determine an initial system certainty value for the computer system;
- provide access to a database of signatures, each signature including a signature certainty value;
- receive data;
- compare the received data with the database of signatures;
- increase the system certainty value if the received data does not match a signature in the database;
- decrease the system certainty value if the received data matches a signature in the database;
- and
- filter the received data based on the system certainty value and the signature certainty value of a signature matching the received data.
