  • Publication number: 20220046055
    Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing an access log of a proxy server device of a content delivery network (CDN) to detect and mitigate a denial of service (DOS) on a web or content server hosted by the CDN. Through an analysis of the content requests received at the proxy server listed in the access logs, one or more IP addresses may be identified as involved in a potential DOS attack or other suspicious behavior. Once identified, the suspicious activities of the one or more IP addresses may be tracked and aggregated over a particular period of time, with each detected suspicious request to the content server being counted. The count of suspicious requests to the content server may then be compared to one or more threshold values and a remediation action may occur when the thresholds are met or exceeded.

  • Patent number: 9415248
    Abstract: A fire extinguishment container including a container body that defines an internal volume and an opening into the internal volume, a cover positionable over the opening, a sealing member positioned between the container body and the cover when the cover is positioned over the opening, wherein the sealing member is formed from a heat-resistant material, and a locking mechanism connected to the container body and the cover to retain the cover over the opening.

  • Patent number: 8640234
    Abstract: A method of managing network usage by defining a set of linguistic patterns, where each linguistic pattern is associated with a condition that is to be monitored. Network packets are captured during transmission and analyzed to identify linguistic patterns. Captured network packets are scored based on similarity of at least one linguistic pattern to one or more of the defined set of linguistic patterns. When a packet that is scored above a specified threshold value is identified, at least one responsive action is implemented. In this manner, a system implementing the method is able to identify network traffic that is associated with prospective malicious activity and thereby provide an early warning before damage has occurred.

  • Patent number: 7577739
    Abstract: A system for monitoring and maintaining an acceptable use policy for network communications monitors, stores and searches for the presence of preselected regular expressions, either by subject category or by keywords. The regular expressions within the subject categories are assigned predetermined values, either negative or positive. If a communication contains regular expressions whose sum of weighted values exceeds a threshold value, the communication is stored for subsequent review by an authorized user of the system. If the communication contains keywords selected by the authorized user, the communication is also stored for subsequent review.
