Read More: In the Help Files under Alerts Management Dashboard. Important: Upgrading to version 7.2.1 from earlier versions has a significant impact on alerts. Before attempting to upgrade to 7.2.1, review the "Upgrade Instructions" on page 18 to avoid losing data and settings. Anomaly Detection Analyze > Anomalies Anomaly Detection provides visibility into abnormalities in your traffic patterns. By evaluating traffic in 10‐minute analysis windows, Anomaly Detection determines which traffic is normal for your network and then creates alerts for outlier network behavior. A mere six hours after Security Analytics 7.2.1 begins to capture traffic, the anomaly detector has established a baseline and will begin to report anomalies. 4 of 29 New in Security Analytics 7.2.1 From an individual anomaly alert, you can pivot to the new Anomaly Investigation summary view for immediate insight into which traffic triggered the alert—then drill down into more specific data through the reports). You can also send the anomaly data to a remote resource for further analysis. Read More: In the Help Files under Data Analysis > Anomaly Detection. Note: Anomaly detection requires an appliance or VM with at least 64GB RAM to function properly. Less memory will result in degraded performance and missed anomalies. To disable anomaly detection, see "Data Enrichment Profiles" on page 9. Data Enrichment The Security Analytics data‐enrichment subsystem has undergone a comprehensive rewrite so that you can deploy the enrichment providers more independently, in terms of both configuration and prioritization. The new system also provides improved data‐enrichment performance and scalability. Important: Upgrading to version 7.2.1 from earlier versions has a significant impact on data‐ enrichment features. Before attempting to upgrade to 7.2.1, review the "Upgrade Instructions" on page 18 to avoid losing data and settings. Real-Time Enrichment Providers Settings > Data Enrichment Traffic that matches the filters in a rule (formerly: “action”) can be sent to one or more real‐time enrichment providers to get a prompt verdict. All of the real‐time enrichment providers can be selected individually for any rule—default or user‐ defined—using any set of filters that you specify. Blue Coat Intelligence Services The functionality of the ThreatBLADES has been consolidated into two Blue Coat Intelligence Services: File Reputation Service—The SHA256 hashes of files that match a rule are sent to the Blue Coat Global Intelligence Network (GIN), which returns a verdict based on the file‐reputation information from more than 15,000 customers and 75 million endpoints that contribute to GIN’s threat intelligence, which includes: •A black list of 3.5 billion file hashes • Additional black and white lists from three major security organizations •Malware Analysis detonation results from the field •Research results from Blue Coat Labs 5 of 29 Security Analytics 7.2.1 43768 Release Notes Web Reputation Service—The URLs that are associated with artifacts that match a rule are sent to GIN, which returns one or more URL categories that Security Analytics evaluates for threat level. Read More: In the Help Files under Data Enrichment > Enrichment Providers > Intelligence Services. Blue Coat Analysis Providers ICAP—Send ICAP service objects to Blue Coat Content Analysis. Malware Analysis—No longer dependent on ThreatBLADES for real‐time enrichment, Malware Analysis can operate in conjunction with—or independently of—the File Reputation Service. •With the FRS Prefilter setting (enabled by default) you can get a verdict on files that are already known to the File Reputation Service without sending them to Malware Analysis. •With the default per‐environment task settings available in Malware Analysis 4.2.x, you can select iVM plugins such as ghost_user.py to apply to samples sent from Security Analytics. •Samples sent to Malware Analysis retain their original filenames. •New file types are sent to Malware Analysis: BAT, COM, DEB, PS1, IPA •Malware Analysis now supports iOS (IPA) in the Mobile IntelliVM. Read More: In the Help Files under Data Enrichment > Enrichment Providers > Analysis Providers. Local File Analysis As separated entities that you can select for real‐time enrichment, Local File Analysis comprises five providers. Important: Upgrading to version 7.2.1 from earlier versions has a significant impact on Local File Analysis providers. Before attempting to upgrade to 7.2.1, review the "Upgrade

    The most dangerous cyber nightmares in recent years Halloween is the time of year for dressing up, watching scary movies, and telling hair-raising tales. Events in recent years have kept companies on high alert. Every day we are seeing an increase in cyberattacks carried out by organized hacker organizations. In a matter of seconds, these threats can destabilize large corporations, stealing large quantities of money and personal data, as well shake the very foundations of entire world powers. Have a look at some of the most terrifying attacks of recent years. 2010 2011 2012 Operation Aurora RSA SecurID Stratfor A series of cyberattacks carried out RSA suffered a security breach as a Publication and dissemination of worldwide, targeting 34 companies, result of a cyberattack that sought internal emails exchanged between including Google.
