Cyber Security operations center is protecting organizations and the sensitive business data of customers.
It ensures active monitoring of valuable assets of the business with visibility, alerting and investigating threats, and a holistic approach to managing risk.
Analytics service can be an in-house or managed security service. Collecting event logs and analyzing logs with real-world attacks is the heart of the security operation center.
Events are generated by systems that are error codes, devices generate events with success or failure to their normal function.
so event logging plays an important role to detect threats. In the organization, there are multiple numbers and flavors of Windows, Linux, firewalls, IDS, IPS, Proxy, Netflow, ODBC, AWS, Vmware, etc.
These devices usually track attackers’ footprints as logs and forward them to SIEM tools for analysis. In this article, will see how events are pushed to the log collector. To know more about Windows events or event ids refer Here.
It’s a centralized server to receive logs from any device. Here I have deployed Snare Agent on Windows 10 machine.
So we will collect Windows event logs and Detect attacks on Windows 10 machines attacks using Snare Agent.
The snare is SIEM(SECURITY INCIDENT AND EVENT MANAGEMENT) Solution for log collector and event analyzer in various operating systems Windows, Linux, OSX Apple, and supports database agent MSSQL events generated by Microsoft SQL Server. It supports both Enterprise and Opensource Agents.
NOTE: Logs can be sent to a centralized server, then the centralized server push logs to SIEM (To reduce the load in SIEM this method is used), send snare logs directly to SIEM (If your SIEM is capable of good storage for a long and short-term log retention this method can be deployed), It recommended to configure your SIEM with port details of snare and test connection should be the successor to collect logs.
NOTE: Above figures shows failed attempts followed by a successful login.
Correlation Rule : failed password attempts + Followed by successful Login = Brute-force (Incident)
Now your customer environment is ready for a Known use case(Brute-force detected), you can also build or write your own use case and deploy it in your SIEM to detect sophisticated cyber-attacks !!!
