Abstract: A server in a captive portal accepts a connection from a user device to the IP address of the server and receives a HTTP or HTTPS request over the connection. The connection may be a result of the user device being previously determined to be not logged in, and consequently provided the IP address of the server as a DNS resolved IP address, the user device thereafter caching the IP address of the server. The server responds with requested content if the target host of the request is a local host. If the target host is a remote destination, the server queries a login database to determine whether the user device is logged in. The server acts as a transparent proxy between the user device and the remote destination if the user device is logged in, else the server sends alternate content to the user device over the connection.

Abstract: Malicious activity data is obtained, that is indicative of attempted attacks on a computing system. Clusters of targets are identified and it is determined whether the malicious activity preferentially targets one cluster of targets over other. Also, low prevalence attacks are identified and it is determined whether a low prevalence attack has a high concentration in one or more of the target clusters. If the malicious activity either preferentially targets a cluster, or a low prevalence attack has a high concentration in a cluster, then the attack is identified as a targeted attack, so that remediation steps can be taken.

Abstract: A security management system may be remotely deployed (e.g., using a cloud-based architecture) to add security to an enterprise network. For example, the security management system may scan assets within the enterprise network for vulnerabilities and may receive data from these scans. The security management system may also receive data from other sources, and, as a result, the system may handle data having many different formats and attributes. When the security management system tries to associate data to assets, there may not be a globally unique identifier that is applicable for all received data. Provided in the present disclosure are exemplary techniques for tracking assets across a network using an asset correlation engine that can flexibly correlate data with assets based on attribute information.

Abstract: A method of detecting patterns in network traffic is provided. The method includes receiving a plurality of packets of network traffic, each packet having a payload populated with payload data and selecting payload lengths that occurred most frequently. For each of the selected payload lengths, a pattern template is generated using characters per position of the payload that satisfy a frequency criterion. A bit encoding scheme is assigned for each of the selected payload lengths and its associated pattern template. Each packet of the plurality of packets that has a payload length equal to any of the selected payload lengths and payload content that matches a pattern template generated for the payload is encoded into a single value. The single value uses the bit encoding scheme for the payload length and the pattern template matched.
