Disclosed herein are methods and systems for transferring trust between authentication devices associated with the same user. The user accessing secure online resource(s) uses a first (authentication) client device which is not yet associated (verified) with the user for accessing the secure online resource(s). In response to receiving an authentication request from the client device, an authentication message is transmitted to the first client device. The authentication message is transferred from the first client device to a second client device already associated (verified) with the user for accessing the secure online resource(s). The second authenticator transmits back the authentication message which may be verified against the authentication message transmitted to the first client device. In case of successful verification, the first authenticator is associated with the user and enabled for authenticating the user when accessing for secure online resource(s) based on identity assurance indicator(s) verified for the second client device.

Transfer of trust between authentication devices

Disclosed herein are systems and methods for recovering online services user accounts of users based on verification of the users in video conferences, comprising receiving a request for recovering an account of a user of an online service, establishing one or more video conference sessions between a client device used by the user, client devices used by one or more trustees associated with the user and a bot agent initiated for the video conference session(s), operating the bot agent during the one or more video conference sessions to guide the one or more trustees to verify an identity of the user, and initiating an account recovery process for the account of the user in response to receiving a positive verification verdict from the one or more trustees.

Peer-supervised video conference based account recovery

Disclosed herein are methods, systems and device for estimating an identity confidence level for a user requesting access to a secure resource, comprising: initiating an authentication session to authenticate the user using a client device to access the secure resource, computing a cumulative identity confidence score in a plurality of iterations and successfully authenticating the user in case the cumulative identity confidence score exceeds a threshold predefined for the secure resource. Each iteration comprising initiating a respective one of a plurality of authentication methods selected according to contextual authentication attribute(s) identified for the authentications session, computing an identity confidence score for the user in case of successful authentication, adjusting the confidence score according to the contextual authentication attribute(s), updating the cumulative identity confidence score according to the adjusted identity confidence score and initiating another iteration in case the cumulative identity confidence score does not exceed the predefined threshold.

Contextual scoring of authenticators

A computerized method of reducing a probability for falsely classifying a legitimate authentication process conducted by a legitimate user as a password guessing attack, comprising estimating a password guessing attack risk for an authentication process conducted by a user for accessing a secure service by performing the following for each of a plurality of failed access attempts in which the user provides incorrect authentication credentials: (1) calculate a risk score for a respective failed access attempt based on analysis of the incorrect authentication credentials provided during the respective failed access attempt and (2) update an authentication session score of the authentication process according to the calculated risk score and initiate one or more actions in case the updated authentication session value exceeds one or more threshold values extracted from a security policy predefined for the secure service.

Risk based brute-force attack prevention

A system for enforcing a security policy on an application stored at a mobile device has an application at the device provided with software code for issuing a request for authenticating a user, and a security enforcement unit; an authentication agent at the device, which is separate from the application, and which is configured with an authentication data collecting unit for collecting authentication data upon receipt of the request for user authentication from the application, and for conveying the collected authentication data to an authentication-authorization server; and an authentication-authorization server for receiving the collected authentication data, evaluating the same, and issuing an enforcement level signal which is conveyed to the security enforcement unit. Upon receipt of the enforcement level signal, the security enforcement unit accordingly applies a security level at the application.

User authentication and authorization system for a mobile application

Managing denial-of-service attacks by intercepting a query by a client software executed by a computer to resolve at a DNS server a network address associated with a target computer system, determining if the DNS server is under denial-of-service attack, and providing to the client software, in response to the query, an alternate network address associated with the target computer system if the DNS server is under denial-of-service attack.

Defense against DNS DoS attack

A system for automatic stability determination and deployment of discrete parts of a profile representing normal behavior to provide fast protection of web applications is disclosed. The system, in response to a sensor collecting from HTTP requests sent by the clients to the web application installed on the protected device, automatically creates for a web application a profile with discrete parts that will represent normal behavior so that deviations from the profile can be considered anomalous. The system automatically determines that a first of the discrete parts of the profile has become stable. The system then automatically deploys the first discrete part of the profile to the sensor that now will compare with the first discrete part of the profile subsequent HTTP requests sent by the clients to the web application to detect deviations from the normal behavior represented by the first discrete part.

Automatic stability determination and deployment of discrete parts of a profile representing normal behavior to provide fast protection of web applications

A computer implemented user authentication method, according to which a mobile application is installed on the mobile terminal device of the user and when the user inputs his username and password, the mobile application creates a private and public encryption keys and encrypts the password with the public key. Data including the encrypted password, the username and the public key is sent to a dedicated server and stored therein as an encrypted file under the username, along with information required for contacting the user's mobile terminal device. The user to selects, and enrolls to, an advanced authentication mechanism, which creates an authentication key for validating the identity of the user and encrypting the private key. The encrypted private key is stored on the user's terminal device. Upon launching the mobile application, the user selects a preferred advanced authentication mechanism which returns an authentication key upon successful authentication of the user. The authentication key is used to decrypt the encrypted private key. Then the encrypted password for the user is retrieved and the private key is used to decrypt the user's password. The user's username and password are then forwarded to the mobile application, to complete the authentication.

Authentication method and system using password as the authentication key

A method for detecting HTML-modifying malware present in a computer includes providing a server which serves a web page (HTML) to a browser. A determination is made whether a modified string exists in the page received by the browser and if a modifying element is found, determining the malware is present in the computer.

Web based remote malware detection

A method for protecting a browser from malicious processes, comprises providing at least one process-proxy object and at least a browser-proxy object, interposed between the browser and a process, such that when the process invokes one of the DOM entry points, the process-proxy object isolates it from the real browser implementation and executes the process-proxy object's code instead.

Remote DOM access

A method for alerting a service provider and/or a user of a web browser of a phishing attempt comprises providing on a page that it is desired to protect against phishing, a Javascript that when caused by a phishing page to run not in the context of the original page generates an indication that a phishing attempt may exist.

Detection of phishing attempts

A method for defending a computer system comprising a DNS server against a DoS or a DDoS attack directed at said DNS server comprises replacing the address of said system provided by a user to a client software with an alternative address, wherein said address is replaced by a software agent associated with said user, such that said client software is capable of connecting with said system.

A browser plug-in firewall manages data exchanged between a browser and a plug-in according to a pre-defined list of rights.
