Device-based security scoring

A method comprising:

• evaluating, by a processor, security of a mobile device with respect to a plurality of factors;
• determining, by the processor, a temporal application score associated with the mobile device representing an evaluation of one or more applications on the mobile device over a time period;
• determining, by the processor, a vulnerability posture of the mobile device representing security exposures of an operating system version, a firmware version, or a hardware associated with the mobile device;
• determining, by the processor, security events associated with the mobile device and representing actions of a user associated with the mobile device;
• determining, by the processor, a security score representing a security posture of the mobile device, the security score being based on the temporal application score, the vulnerability posture, and the security events associated with the mobile device;
• and
• providing, by the processor, the security score;
• wherein the plurality of factors includes a characterization of network activity of the mobile device;
• wherein the characterization of the network activity of the mobile device includes at least one of:
• a quantity of data transmitted using a wireless local area network;
• a quantity of data transmitted using a cellular communication network;
• a quantity of data received using a wireless local area network;
• and
• a quantity of data received using a cellular communication network;
• wherein the characterization of the network activity of the mobile device includes:
• whether the mobile device is detected using the cellular communication network while within transmission range of the wireless local area network.

A mobile device comprising:

• one or more processing devices;
• one or more memory devices coupled to the one or more processing devices, the one or more memory devices storing executable code that, when executed by the one or more processing devices, causes the one or more processing devices to:
• evaluate security of a mobile device with respect to a plurality of factors;
• determine a temporal application score associated with the mobile device representing an evaluation of one or more applications on the mobile device over a time period, the temporal application score being based on change over the time period in a number of the one or more applications corresponding to each type of a plurality of application types;
• determine a vulnerability posture of the mobile device representing security exposures of an operating system version, a firmware version, or a hardware associated with the mobile device;
• determine security events associated with the mobile device and representing actions of a user associated with the mobile device;
• determine a security score representing a security posture of the mobile device, the security score being based on the temporal application score, the vulnerability posture, and the security events associated with the mobile device;
• and
• provide the security score.

A non-transitory computer-readable medium storing executable code that, when executed by one or more processing devices of a mobile device, causes the one or more processing devices to:

• evaluate security of a mobile device with respect to a plurality of factors;
• determine a temporal application score associated with the mobile device representing an evaluation of one or more applications on the mobile device over a time period, the temporal application score being based on change, over the time period, in a number of the one or more applications having a critical level of risk;
• determine a vulnerability posture of the mobile device representing security exposures of an operating system version, a firmware version, or a hardware associated with the mobile device;
• determine security events associated with the mobile device and representing actions of a user associated with the mobile device;
• determine a security score representing a security posture of the mobile device, the security score being based on the temporal application score, the vulnerability posture, and the security events associated with the mobile device;
• and
• provide the security score.
