SecureOps Lab - Live Cybersecurity Assessment

Overview

Performed a live cybersecurity assessment on a university Linux server. During analysis, active attack activity was identified, including brute-force authentication attempts and exploitation attempts targeting Log4Shell (CVE-2021-44228).

“Coordinated IPs” refers to multiple malicious IP addresses originating from the same subnet, indicating the use of shared attack infrastructure or automated attack tooling targeting the system simultaneously.

Threat Analysis & Findings

Brute Force Attack

  • Detected 144 failed SSH login attempts from a single external IP
  • Pattern analysis showed rapid authentication attempts consistent with automated credential stuffing

Log4Shell Exploitation Attempts

  • Identified malicious payloads in logs consistent with CVE-2021-44228 exploitation attempts
  • Source IP differed from brute-force attacker but originated from the same subnet, suggesting coordinated activity

Tools & Technical Application

Nmap

Used for active reconnaissance and attack surface enumeration:

  • Identified open ports and exposed services
  • Detected SSH service configuration and potential entry points
  • Assessed externally reachable services for risk exposure

Lynis

Performed host-based security auditing:

  • Generated system hardening score (initial: 62)
  • Identified misconfigurations in authentication, logging, and service permissions
  • Highlighted compliance gaps and privilege risks

Custom Bash Scripts

Developed scripts to automate security monitoring:

  • Parsed journald logs for failed authentication attempts
  • Detected attack patterns and suspicious IP activity
  • Generated SOC-style alert reports for incident visibility

Risk Assessment (GRC Approach)

A total of 12 security findings were documented and categorized:

  • High Risk:
    • SSH root login enabled
    • Unlimited authentication attempts
  • Medium Risk:
    • Weak account permission structures
    • Insufficient logging and monitoring visibility
  • Low Risk:
    • Minor configuration inefficiencies

Risk Methodology

  • Severity assessed using:
    • CVE references (e.g., CVE-2021-44228)
    • CVSS scoring standards
    • Likelihood vs impact analysis

Remediation & Hardening Actions

SSH Hardening

  • Disabled root login (PermitRootLogin no)
  • Limited authentication attempts (MaxAuthTries 3)
  • Reduced brute-force attack surface

Identity & Access Management (IAM)

  • Audited all user accounts
  • Removed unnecessary or inactive accounts
  • Enforced least-privilege access controls

System Monitoring Improvements

  • Enhanced log visibility using journald analysis
  • Implemented automated alerting via Bash scripts

Results

  • Identified and documented 12 security risks
  • Improved system hardening score from 62 → 64
  • Reduced attack surface and mitigated active threats
  • Established repeatable security monitoring workflows
