6 Open-Source Tools To Save Your Data Over Cloud


Cloud computing’s rapid acceptance has helped corporations to scale up their operations, but it also made cloud-based data more prone to regular breaches. Hosting an in-house security monitoring team is daunting, and the resources available today are cost-restricting, sluggish, and on a scale somewhat unmanageable. Security teams need more power, flexibility, and visibility to stay safeguarded in the cloud. This is where open-source comes into the picture, the benefits of open-source focuses around lower cost and in the control of a dedicated community.

In this post, we highlighted six open-source cloud security tools and how they help security teams by detecting anomalies and malicious activity keep their organization safe from hackers and cybercriminals.

Facebook creates it as an open-source and easily accessible platform for Windows, macOS, CentOS, FreeBSD.

On all platforms, it continues to test for memory leaks, thread safety, and binary reproducibility.

Osqueryd takes care of queries within the osquery, allowing scheduled queries to be performed through the entire infrastructure.

The generated logs are also considered for the maintenance of insights into security, performance, and configuration. 

Furthermore, users can detect malicious activities for scheduled queries.

In June 2019, Linux released an official statement of overtaking the controls of osquery from Facebook.


  • Can execute scheduled queries.
  • Using osqueryi, try out new queries with the SQL interface.
  • Can extract data from Docker containers.


It is also known as the Graph Analytics Platform. Grapl is an open-source platform for detection and response. 

Usually, a graph is composed of nodes and edges. Nodes are comparable to entities, while edges represent the node relationship.

Although Graphs may seem to many an ordinary image, hackers can still use them to derive information from it.

Grapl is an effort to understand user behavior with the help of graphs instead of logs. 

It takes security logs into account and converts them into sub-graphs. 

After that, all the graphs are merged into master graphs that represent user behavior. 


OSSEC primarily focuses on the detections of server intrusion for both cloud and on-premise.

Majority of the functions that OSSEC undertakes for server security are:

  • Log analysis.
  • Integrity checking.
  • Active response.
  • Rootkit detection.
  • Windows registry monitoring.


  • It collects data in real-time from multiple points.
  • It can detect malicious applications. 
  • Log-based intrusion detectors.

The Open Information Security Foundation released Suricata in 2009.

It can detect intrusions and prevent inline intrusions. Moreover, it can help in network security monitoring and offline PCAP processing. 

Suricata is rule-based, where a unique characteristic within the network traffic can be given for a specific definition. 

It helps in alerting when the required conditions are met and decides whether the communication should be allowed or dropped. 

Moreover, its community primarily focuses on security, usability, and efficiency. 


  • Automatic protocol detection.
  • Lua scripting.
  • Multi-threading.


This tool was created in 1994 and previously known as Bro, but in 2018 it was renamed as Zeek at BroCon. 

It is an open-source software for network analysis framework. 

Other than network monitoring Zeek is also capable in:

  • Performing incident response.
  • Efficient forensics, thus it can provide high-level records of a network’s activity.
  • Converting network traffic data into higher-level events.
  • Providing a script interpreter.


  • In-depth analysis.
  • Open interfaces.
  • Being flexible allows it not to be dependent on traditional signatures.


It is a continuous security monitoring platform.

Panther analyzes data generation by clouds, networks, and applications for threat detection as well as security.

Python detection logic provided by Panther enables the detection of malicious behavior, threat hunting, and secured cloud resources.


  • Continuous monitoring.
  • Automatic remediation.
  • Unauthorized access detection.

Final Words

Most of the businesses are moving to the cloud, helping them to rise faster than ever. However, security issues are also increasing at a similar rate. 

Open-source tools can help organizations of any scale by providing security and analysis at an affordable price.
