● Performance and Limitations

1. Design Philosophy

K-Scanner prioritizes operational safety over aggressive inspection.

It performs read-only analysis of /proc/[PID]/maps without:

  • Attaching debuggers
  • Pausing processes
  • Reading raw memory pages
  • Using intrusive syscalls such as ptrace

This ensures minimal impact on production systems.


2. Performance Characteristics

The scanner's workload depends primarily on:

  • Number of running processes
  • Size of each memory map file
  • Scan frequency (in live mode)

Since it inspects metadata only, the overhead is generally low.

In typical Linux environments:

  • CPU impact is minimal
  • Memory usage is negligible
  • I/O overhead is limited to /proc reads

However, in systems with thousands of processes, scan frequency should be tuned appropriately.


3. Scalability Considerations

K-Scanner scales linearly with the number of processes.

Large multi-tenant servers may require:

  • Scan interval adjustments
  • Controlled scheduling
  • Integration into monitoring pipelines

It is not optimized for distributed orchestration environments by default.


4. Known Limitations

K-Scanner does not:

  • Monitor historical permission transitions
  • Correlate memory regions with loaded binaries
  • Capture full memory snapshots
  • Analyze kernel-space memory
  • Detect stealth techniques that maintain W^X compliance

It relies entirely on the integrity of /proc metadata.


5. Privilege Requirements

Access to /proc/[PID]/maps may require elevated privileges.

In restricted environments:

  • Some processes may be inaccessible
  • Partial visibility may occur

This behavior depends on system security configuration.


6. Operational Trade-Offs

The primary trade-off in K-Scanner is:

Visibility vs. Intrusiveness

By avoiding deep memory inspection, the tool maintains stability and safety — but sacrifices deep behavioral analysis.

This is a deliberate engineering decision.


7. Recommended Usage Model

K-Scanner is best used as:

  • A lightweight diagnostic utility
  • A pre-forensic triage scanner
  • A complementary security tool

It should be part of a layered defense strategy rather than a standalone detection mechanism.
