The invention discloses an authentication system and a working method thereof and belongs to the information security field. The method includes the following steps that: when receiving an access request, a server generates a first challenge value and sends the first challenge value to a client; the client uses a preset Hash algorithm to carry out Hash calculation on the first challenge value to generate a challenge Hash value; when judging that a received identification code is matched with a pairing code stored in an identity authentication module, the identity authentication module uses a private key corresponding to the pairing code to calculate the challenge the Hash value according to a preset signature algorithm so as to obtain a signature value; the client generates a signature verification request according to the signature value and sends the signature verification request to the server; and the server authenticates the signature verification request, and a user is allowed to access requested resources if the authentication is successful, and the user is not allowed to access the requested resources if the verification fails. With the authentication system and the working method thereof provided by the technical schemes of the invention adopted, communication can be continued as long as the identity authentication module completes local authentication, and therefore, the problem of data leakage in a data transmission process can be prevented, and the security of the communication can be improved.

When a resource-limited device (such as a mobile telephone) joins a network associated with an enterprise, the agent in the device generates digital signatures for all the files in the device and sends them to an enterprise controller. The controller compares them to the global signature database; it filters out the sensitive digital signatures and feeds them back to the agent in the device. The agent receives the feedback of digital signatures and consolidates them into its own local signature database. The agent analyzes each file that is attempting to be output from the device according to the local signature database and DLP policy. If the signature of the file is present in the local database then the action to output file is blocked. If a new file is created on the device, the agent generates and sends its digital signature to the controller for inspection. If the signature is sensitive, this new digital signature will be placed into the local signature database. If the DLP controller updates the global signature database, the device will send its signatures once again for comparison.

A multiplier is utilized to quantify a cybersecurity risk level of a portfolio of entities (e.g., companies) and enable actions to mitigate that quantified risk. In doing so, features or attributes of one or more companies in a portfolio are compared to features or attributes of one or more companies that experienced an adverse cybersecurity event (e.g. a data breach). Further, a degree of dependency, such as a matrix of a number of shared vendors and the proximity of those vendors to the companies, can be measured between (1) portfolio companies and one or more companies that experienced a cybersecurity event, and / or (2) the portfolio companies themselves to better quantify the risk. That is, to more meaningfully analyze a cybersecurity event that occurred at one or more companies and better predict the likelihood of an occurrence at portfolio companies, embodiments can determine an n-degree interdependency between companies.
