Abstract: Described is a technology by which a single physical storage device such as a USB flash memory device is able to boot different computing devices via corresponding different operating systems. The storage device includes a selection mechanism that determines which virtual disk (corresponding to a LUN) is seen by the host as the currently active LUN having sector 0, and therefore is the boot disk. The selection mechanism also may select which (if any) other LUNs are visible to the host. The selection mechanism and accompanying indicator may be operated when the storage device is disconnected, e.g., via manual switches and/or LEDs, buttons and/or a display (e.g., via internal power). Also described is allowing each LUN to have a user-friendly name.

Abstract: Technology is described for protecting transactions. The technology may include a switching component that a user can employ to switch an associated mobile device into a secure mode so that a user can confirm the transaction. After initiating a transaction request, the user can confirm the transaction request by activating the switching component, which can cause the mobile device to switch into a secure mode. In the secure mode, the mobile device may prevent the mobile device from conducting various normal activities, such as executing applications, receiving input, providing output, and so forth. The switching component may disable other processing temporarily. Upon receiving the confirmation from the user, the switching component may send a confirmation communication to complete the transaction.

Abstract: Technology is described for enabling passive enforcement of security at computing systems. A component of a computing system can passively authenticate or authorize a user based on observations of the user's interactions with the computing system. The technology may increase or decrease an authentication or authorization level based on the observations. The level can indicate what level of access the user should be granted. When the user or a component of the computing device initiates a request, an application or service can determine whether the level is sufficient to satisfy the request. If the level is insufficient, the application or service can prompt the user for credentials so that the user is actively authenticated. The technology may enable computing systems to “trust” authentication so that two proximate devices can share authentication levels.

Abstract: Inline pattern matching and policy enforcement may be implemented by a memory storage device. In an example embodiment, a device-implemented method includes acts of receiving, intercepting, and performing and conditional acts of invoking or permitting. A request from a host to perform a memory access operation is received at a memory storage device. Data flowing between an I/O channel and physical storage of the memory storage device is intercepted. A pattern matching procedure is performed on the data with reference to multiple target patterns in real-time while the data is being intercepted. If a pattern match is detected between the data and a target pattern, a policy enforcement mechanism is invoked. If a pattern match is not detected between the data and the multiple target patterns, the request from the host to perform the memory access operation is permitted.

Abstract: Systems and methods that resist malicious attacks on an intelligent storage device via an access control component that supplies security at a dual layer of defense. Such dual layer defense encompasses both resistance to brute force (e.g., unauthorized users), and resistance to a replay attack (e.g., a malicious code residing on a machine that hosts the intelligent storage device.) Accordingly, an access control component includes an anti malicious user component and an anti malicious code component, which can resist malicious attacks from both a person and a host unit with a malicious code residing thereon.

Abstract: Techniques for conducting secure online transactions using captcha images as watermarks are provided. Some techniques combine a trusted, secure device that utilizes a key to generate identifiers with a watermarked transaction verification request page to provide secure online transactions. The trusted, secure devices are provided to users for use in transacting with a transaction provider. In processing a transaction requested by a user, the transaction provider determines an identifier that should be being currently generated by the user's trusted, secure device, creates a captcha image of the identifier, and watermarks a transaction verification request page using the captcha image. The transaction provider then requests that the user verify the transaction described in the transaction verification request page by providing the next identifier that is generated by the user's trusted, secure device to the transaction provider.

Abstract: Key exchanges between peer-to-peer devices can be vulnerable to man in the middle attacks. Verification of the key exchanges can be made on a channel, network and/or device different from the channel, network and/or device used for the key exchange to determine whether the key exchange was secure. Verification of the key exchange can also be made through an established and trusted device and/or entity. If the key exchange was secure, the parties to a communication utilizing the key(s) exchanged can be notified, if desired. If the key exchange was not secure, the parties can be notified and the communication can be selectively disconnected.

Abstract: A unique system and method that facilitates visually identifying authentic UI objects, bundles, or windows is provided. A detection component can detect when user-based input has activated a verification mode with respect to one or more trusted UI objects rendered on-screen. A verification component can verify at least one of a source and identity associated with one or more UI objects in order to ensure the integrity related therewith. A verification rendering engine can re-render the one or more trusted UI objects in a manner that is based at least upon whether the one or more trusted UI objects are verified, thus improving visual recognition of verified trusted UI objects over non-verified UI objects.

Abstract: A method and system for detecting and stopping malware propagation using false resource entries is provided. A detection system uses trap door entries that are intentionally inserted into resource location stores to detect resource misuse. A “trap door” is a false resource that can be monitored by the detection system. The detection system monitors trapdoor entries that have been intentionally inserted into resource location stores, and looks for signs of use. The detection system can then determine whether a detected use of a trap door entry is a misuse of the trap door entry, and upon declaring a misuse of the trap door entry, the detection system can appropriately respond to the misuse.
