19038results about How to "Reduce security risks" patented technology

Secure computation environments are protected from bogus or rogue load modules, executables and other data elements through use of digital signatures, seals and certificates issued by a verifying authority. A verifying authority-which may be a trusted independent third party-tests the load modules or other executables to verify that their corresponding specifications are accurate and complete, and then digitally signs the load module or other executable based on tamper resistance work factor classification. Secure computation environments with different tamper resistance work factors use different verification digital signature authentication techniques (e.g., different signature algorithms and/or signature verification keys)-allowing one tamper resistance work factor environment to protect itself against load modules from another, different tamper resistance work factor environment. Several dissimilar digital signature algorithms may be used to reduce vulnerability from algorithm compromise, and subsets of multiple digital signatures may be used to reduce the scope of any specific compromise.

A camera assembly arranged on an unmanned and autonomously navigating aerial vehicle is employed to inspect a surface area of for material defects. The vehicle is automatically flown to the surface area from a launch site, wherein it can fly around obstacles using automatic obstacle detection and avoidance methods. A relative position of the aerial vehicle with respect to the surface area with the aid of a position sensor is continuously measured and a sequence of images of the surface area is recorded. Between the individual images, the aerial vehicle is moved along a flight path overlapping image details of the surface area. The images of the sequence are composed into an overall image of the surface area to allow for the surface area to be inspected for defects and the location of defects to be ascertained on the basis of the overall image.

Techniques are disclosed for systematically assessing an enterprise's security risks in view of a set of security patterns. Each pattern that is applicable to the enterprise's operation is then considered against the backdrop of a set of common attributes that are used, in turn, to further distinguish each pattern from a risk and security solution perspective. Using the disclosed techniques, specific security risks can be identified and appropriate security products can be selected to address those risks in a systematic manner, thereby assisting information technology decision makers across a wide variety of enterprises in deriving security solutions. These security solutions will typically be more effective and efficient from a functional perspective, as well as being more cost-effective, than security solutions created using prior art ad hoc approaches. The disclosed techniques may also be leveraged to create a requirements list for function to be included in a security product.

A system and method for detecting the mutability of fields and classes in an arbitrary program component written in an object oriented programming language is disclosed. A variable is considered to be mutable if a new value is stored into it, as well as if any of its reachable variables are mutable. The system and method uses a static analysis algorithm which can be applied to any software component rather than whole programs. The analysis classifies fields and classes as either mutable or immutable. In order to facilitate open-world analysis, the algorithm identifies situations that expose variables to potential modification by code outside the component, as well as situations where variables are modified by the analyzed code. An implementation of the analysis is presented which focuses on detecting mutability of class variables, so as to avoid isolation problems. The implementation incorporates intra- and inter-procedural data-flow analyses and is shown to be highly scalable. Experimental results demonstrate the effectiveness of the algorithms.

System and method for generating, disseminating, controlling, and processing limited-life security codes used to authenticate users, particularly for electronic financial transactions, such as payment transactions or interacting with automated teller machines and the like. Providing a user with a single security code usable across multiple accounts or other secured systems is contemplated, each security code having a limited lifetime (e.g., one day). In a particular example of the present invention, a plurality of similarly situated users (each needing authenticated access to a plurality of accounts or other secured systems using the security code) are each assigned a set or group of respective security codes. In a preferred example, each security code is a random number from a random number generator. The respective security codes for each user correspond to a respective security code validity period of limited duration. Thus, a table or matrix that associates the plurality of users with the respective sets of randomly selected security codes (each having their respective validity periods) is generated, and that matrix is provided to the respective entities (such as banks, payment processors, computer networks generally, etc.) to which each user requires secured access. In parallel, at least a current security code (for example, for the current validity period) is provided to each user, and this is how the respective entities being accessed can track which code from which user is currently valid.

One embodiment of the present invention provides a system that performs layer 3 (L3) aware switching in an Ethernet passive optical network (EPON) which includes a central node and at least one remote node. During operation, the system maintains a set of mapping information which indicates a correspondence relationship between a logical link identifier of a remote node, a medium access control (MAC) address for a subscriber coupled to the remote node, and an IP address for the subscriber. Upon receiving a packet which contains an IP address, the system selectively attaches a proper logical link identifier to the packet based on the mapping information and the IP address contained in the packet, thereby allowing only one proper remote node to receive the packet.

A method of securely accessing at a client device content from a server without using the non-volatile memory of the client device is disclosed. The bypassing of non-volatile memory lessens the security risk of unauthorized viewing of the server originated content. An transport mechanism is initiated on a client device and creates a document container. Downloaded documents from a server are mapped into the document container and saved within the document container in volatile memory. Substitute menus are generated within the container to replace application menus. User documents are saved directly to the originating server via the substitute menus. The downloaded copies in volatile memory automatically delete when the document container is destroyed thereby reducing security concerns of unauthorized viewing of the content at the client device.
