File access

WHAT

Runtime detection tools, such as Jibril, are designed to monitor system activity in real-time to identify suspicious behaviors that may indicate a security breach or an intrusion attempt. These tools analyze various system operations, including file access patterns, process executions, network connections, and other system interactions.

HOW

  1. File Monitoring: Jibril tracks the files that are opened by different applications. It logs details such as file names, file paths, the process responsible for accessing the file, and the time of access.

  2. Action Analysis: It examines the types of actions taken on these files—whether they are read, written, executed, or modified. This is crucial because unauthorized modifications or executions can be indicative of malicious activity.

  3. Context Evaluation: The conditions under which these actions are taken are scrutinized. This includes checking the user permissions under which the files were accessed, the time of access (e.g., unusual times like late nights or early mornings), and whether the access patterns deviate from normal behavior profiles.

  4. Application Correlation: Jibril correlates each action to its originating application by examining process IDs and other metadata. This helps in identifying potentially rogue applications or processes masquerading as legitimate ones.

WHERE

Jibril would typically be deployed at critical points within an IT infrastructure:

  • Endpoints: Installed on individual workstations or servers to monitor local activities.
  • Network Gateways: Deployed at demarcation points to analyze traffic entering or leaving the network.
  • Data Centers: Used in data centers to oversee activities across multiple systems simultaneously.

WHY

  1. Security Enhancement: By monitoring how files are accessed and manipulated, Jibril helps in early detection of unauthorized access and potential data breaches.

  2. Forensic Analysis: The detailed logging facilitates forensic analysis post an incident to determine how a breach occurred and assess the extent of damage.

  3. Compliance Assurance: Ensures compliance with security policies and regulatory requirements by enforcing rules about how sensitive information must be handled.

  4. Proactive Threat Mitigation: Helps in identifying suspicious patterns that could evolve into more serious threats, allowing IT security teams to respond proactively rather than reactively.

CONCLUSION

In summary, runtime detection tools like Jibril play a crucial role in maintaining cybersecurity by continuously monitoring system activities for signs of intrusion based on file interactions and contextual information associated with these interactions.
