Methods and systems for efficient adaptive logging of cyber threat incidents
A packet-filtering network appliance such as a threat intelligence gateway (TIG) protects TCP/IP networks from Internet threats by enforcing certain policies on in-transit packets that are crossing network boundaries. The policies are composed of packet filtering rules derived from cyber threat intelligence (CTI). Logs of rule-matching packets and their associated flows are sent to cyberanalysis applications located at security operations centers (SOCs) and operated by cyberanalysts. Some cyber threats/attacks, or incidents, are composed of many different flows occurring at a very high rate, which generates a flood of logs that may overwhelm computer, storage, network, and cyberanalysis resources, thereby compromising cyber defenses. The present disclosure describes incident logging, in which a single incident log efficiently incorporates the logs of the many flows that comprise the incident, thereby potentially reducing resource consumption while improving the informational/cyberanalytical value of the incident log for cyberanalysis when compared to the component flow logs. Incident logging vs. flow logging can be automatically and adaptively switched on or off depending on the combination of resource consumption and informational/cyberanalytical value. |

Optical network, optical transport system, and optical node included therein
In optical transmission schemes of the related art, there is a problem of delay dependency on an overhead or a flow size. In a DC network and a supercomputer network, an OCS scheme and an OPS scheme remain in an examination stage. A network of the electrical packet switching is still a main stream. In a scheme of sharing links using a dedicated wavelength, a considerable number of wavelengths is also necessary to provide full connectivity. The number of wavelengths cannot be realized and an unrealistic number considering the usable number of wavelengths such as current used C bands. In an optical network and an optical transmission system of the present invention, burst mode data transmission in which a label-based switching on an exclusively reserved dedicated wavelength is used is performed. Each node has a uniquely allocated wavelength, and thus traffics coexisting in all the network nodes do not collide. By using an optical label processor, an overhead time for establishing links between nodes is unnecessary. Reuse of the same wavelength results in further decrease in the number of wavelengths. |
