Methods and systems for analyzing data after initial analyses by known good and known bad security components
Methods and systems are provided for conditionally allowing a mobile communications device to process received data. Initially, the data is analyzed by a known good component without the component determining that the data is safe, and the data is analyzed by a known bad component without the component determining that the data is malicious. Subsequently, the data is analyzed by a decision component on the mobile communications device. When the decision component determines the data to be safe, the decision component allows the mobile communications device to process the data. When the decision component determined the data to be malicious, the decision component prevents the mobile communications device from processing the data.
1. A method comprising:
receiving, by a decision component executing on a mobile communications device (MCD), data from a known bad component executing on the MCD, the data including first information regarding a set of requests and second information regarding a set of user responses to the set of requests, after:
the data was analyzed, by a known good component executing on the MCD, in an attempt to determine whether the data is safe, the determination being that the known good component does not consider the data to be safe; and
the data was analyzed, by the known bad component executing on the MCD, in an attempt to determine whether the data is malicious, the determination being that the known bad component does not consider the data to be malicious;
analyzing, by the decision component, the data to determine whether the data is safe or malicious by analyzing the first information and the second information for a temporal component indicative of malicious behavior, the data being determined to be safe when the analysis of the data does not find a temporal component indicative of malicious behavior and the data being determined to be malicious when the analysis of the data finds a temporal component indicative of malicious behavior; and
when the decision component determines that the data is safe, allowing the data to be further processed by the MCD; or
when the decision component determines that the data is malicious, preventing the data from being further processed by the MCD.
2. The method of claim 1 , wherein the analyzing, by the decision component, the data to determine whether the data is safe further includes:
assessing, by the decision component, the data to determine whether the data contains first characteristics that are characteristic of safe data;
assessing, by the decision component, the data to determine whether the data contains second characteristics that are characteristic of malicious data; and
assigning, by the decision component, a degree the data is safe or malicious based on the determined first and second characteristics, the degree representing a location on a scale between the data being safe and the data being malicious.
3. The method of claim 2 , wherein:
the data is determined to be safe when the location on the scale indicates the data is more safe than malicious and when the analysis of the data does not find a temporal component indicative of malicious behavior; and
the data is determined to be malicious when the location on the scale indicates the data is more malicious than safe and when the analysis of the data finds a temporal component indicative of malicious behavior.
4. The method of claim 1 , wherein the temporal component is indicative of one of:
an attempt to frustrate the user;
a denial of service attack; or
a port scan attack.
5. The method of claim 1 , wherein the analyzing the data to determine whether the data is safe includes analyzing the data to determine whether:
the data includes false data, or
a purported origin of the data is not legitimate; and
the data is determined to be safe when the analysis of the data determines the data does not include false data and the purported origin is legitimate and when the analysis of the data does not find a temporal component indicative of malicious behavior; and
the data is determined to be malicious when the analysis of the data determines the data does includes false data or the purported origin is not legitimate and when the analysis of the data finds a temporal component indicative of malicious behavior.
6. A non-transitory, computer-readable storage medium having stored thereon a plurality of instructions, which, when executed by a processor of a mobile communications device (MCD), cause the MCD to:
receive, by a decision component executing on the MCD, data from a known bad component executing on the MCD, the data including first information regarding a set of requests and second information regarding a set of user responses to the set of requests, after:
the data was analyzed, by a known good component executing on the MCD, in an attempt to determine whether the data is safe, the determination being that the known good component does not consider the data to be safe; and
the data was analyzed, by the known bad component executing on the MCD, in an attempt to determine whether the data is malicious, the determination being that the known bad component does not consider the data to be malicious;
analyze, by the decision component, the data to determine whether the data is safe or malicious by analyzing the first information and the second information for a temporal component indicative of malicious behavior, the data being determined to be safe when the analysis of the data does not find a temporal component indicative of malicious behavior and the data being determined to be malicious when the analysis of the data finds a temporal component indicative of malicious behavior; and
allow the data to be further processed when the decision component determines that the data is safe; or
prevent the data from being further processed when the decision component determines that the data is malicious.
7. The computer-readable storage medium of claim 6 , wherein the instructions to analyze, by the decision component, the data to determine whether the data is safe includes further instructions to:
assess, by the decision component, the data to determine whether the data contains first characteristics that are characteristic of safe data;
assess, by the decision component, the data to determine whether the data contains second characteristics that are characteristic of malicious data; and
assign, by the decision component, a degree the data is safe or malicious based on the determined first and second characteristics, the degree representing a location on a scale between the data being safe and the data being malicious.
8. The computer-readable storage medium of claim 7 , wherein:
the data is determined to be safe when the location on the scale indicates the data is more safe than malicious and when the analysis of the data does not find a temporal component indicative of malicious behavior; and
the data is determined to be malicious when the location on the scale indicates the data is more malicious than safe and when the analysis of the data finds a temporal component indicative of malicious behavior.
