STA is a tool for analyzing network traffic and host based activities. Using open-source services such as
suricata, it enriches these events with other internal services.
To reduce the total cost of ownership of the STA, we have introduced a new insights service within the STA that will automatically detect possible threats and security related anomalies in your traffic.
Using the Coralogix Platform, configure alerts based on those insights and receive instant notifications if anomalies occur.
The following table contains a detailed list of the possible insights that can be detected by the
To reduce the chances for false-positives, during the first three days the STA will only learn the patterns seen in the traffic. After that it will start sending events about anomalies to Coralogix.
|Name||Description||Possible Attacks||Message||Sub Message|
|File Similarity Insight||changes to file paths that are very similar to others which encountered recently||File encryption based Ransomware|
|Connection To Suspiciously Looking Domain Name||connections to suspicious domain using frequency score algorithms||DGA activities|
|Connection to baby domains||connections to domains that created less than 90 days||Phishing, C2C attacks|
|Connection to possible malicious IPs/Domains||connection to IPs/Domains which flagged as malicious by at least one DNSRBL||Phishing, C2C attacks|
|New top level domain||encountered with new top level domain||Phishing, C2C attacks|
|Connection with redirection to another domain||connection to URL which redirects to another domain||Evasion techniques|

After insight events are sent to Coralogix, you can find them under the
Explore section with subsystem name
To enable alerts from within Coralogix, navigate to the
Alerts section and set them accordingly. Find out more regarding alerts here.
