Information sharing covers a wide range of issues related to security, including viruses, malware, intrusion detection and firewalls. Its automated tools cleanse, aggregate, validate and publish data shared by participants.[4] The data is validated by the OTX platform then stripped of information identifying the participating contributor.[6] In 2015, OTX 2.0 added a social network which enables members to share, discuss and research security threats, including via a real-time threat feed.[9] Users can share the IP addresses or websites from where attacks originated or look up specific threats to see if anyone has already left such information.[10] Users can subscribe to a “Pulse,” an analysis of a specific threat, including data on IoC, impact, and the targeted software. Pulses can be exported as STIX, JSON, OpenloC, MAEC and CSV, and can be used to automatically update local security products.[9] Users can up-vote and comment on specific pulses to assist others in identifying the most important threats.[12] OTX combines social contributions with automated machine-to-machine tools that integrates with major security products such as firewalls and perimeter security hardware.[10] The platform can read security report in .pdf, .csv, .json and other open formats. Relevant information is extracted automatically, assisting IT professionals to more readily analyze data.[10] Specific OTX components include a dashboard with details about the top malicious IPs around the world and to check the status of specific IPs; notifications should an organization's IP or domain be found in a hacker forum, blacklist or be listed by in OTX; and a feature to review log files to determine if there has been communication with known malicious IPs.[6] In 2016, AlienVault released a new version of OTX allowing participants to create private communities and discussions groups to share information on threats only within the group. The feature is intended to facilitate more in-depth discussions on specific threats, particular industries, and different regions of the world. Threat data from groups can also be distributed to subscribers of managed service providers using OTX."[1] TechnologyOTX is a big data platform that integrates natural language processing and machine learning to facilitate the collection and correlation of data from many sources, including third-party threat feeds, websites, external API and local agents.[2] PartnersIn 2015, AlienVault partnered with Intel to coordinate real-time threat information on OTX.[18] A similar deal with Hewlett Packard was announced the same year.[1] CompetitorsBoth Facebook and IBM have threat exchange platforms. The Facebook ThreatExchange is in beta and requires an application or invitation to join.[20] IBM launched IBM-Force Exchange in April 2015.[3] References 1 : Computer security |
