Audit Methodology

Our 5-Stage Diagnostic Framework

We combine rigorous automated scanning with expert manual configuration review:

STAGE 01External Exposure Mapping

Perimeter Reconnaissance & Port Diagnostics

We map all exposed TCP/UDP sockets, analyze firewall packet filtering, test for unauthenticated listening services, and identify unexpected public daemons.

STAGE 02Deep 320+ Checkpoint Diagnostic

Automated Lynis & CIS Benchmark Engine

Executing comprehensive Lynis enterprise scans across kernel parameters, bootloader passwords, PAM authentication thresholds, and file permissions.

STAGE 03Local Exploit Surface Inspection

Privilege Escalation & SUID Binary Audit

Auditing SUID/SGID binaries, world-writable cron jobs, sudoers configuration flaws (NOPASSWD), and unmasked kernel pointer vectors (/proc/kallsyms).

STAGE 04Application Gateway Inspection

Web Stack, Reverse Proxy & Database Fortification

Analyzing Nginx/Apache cipher suites (SSL Labs grade check), HTTP security headers, PHP-FPM execution sandboxes, and database network interface binding.

STAGE 05Actionable Engineering Deliverable

Executive PDF Report & Prioritized Remediation

Delivering a customized executive PDF report containing CVSS 3.1 risk scores, compliance metrics, and copy-paste remediation scripts for your team.

Vulnerability Diagnostic Matrix

Sample Findings & Prioritized Remediation

VULN-01Critical (CVSS 9.1)Network Exposure

Direct MySQL / PostgreSQL Port 3306/5432 Exposed to Public 0.0.0.0

Database daemon is listening on public network interface without firewall whitelist, vulnerable to brute-force credential stuffing and zero-day unauthenticated RCE exploits.

Remediation Blueprint:
bind-address = 127.0.0.1 in my.cnf + NFTables drop rule on public interface
VULN-02Critical (CVSS 8.8)Authentication

Password-Based Root SSH Authentication Active on Default Port 22

Automated dictionary attack bots generate 40,000+ login attempts per day against root user. Single weak credential compromises entire server cluster.

Remediation Blueprint:
PermitRootLogin no + PasswordAuthentication no + Ed25519 Pubkey only
VULN-03High (CVSS 7.8)Kernel Security

Unmasked Kernel Pointers in /proc/kallsyms (kptr_restrict = 0)

Local unprivileged users and compromised web shell scripts can read raw kernel memory addresses, facilitating kernel privilege escalation exploits.

Remediation Blueprint:
sysctl -w kernel.kptr_restrict=2 && kernel.dmesg_restrict=1
VULN-04High (CVSS 7.5)Filesystem Integrity

World-Writable /tmp Directory Lacks noexec and nosuid Mount Options

Web application vulnerabilities (e.g. PHP file upload) allow attackers to write and execute compiled binary malware payloads directly from /tmp.

Remediation Blueprint:
Mount /tmp with options: rw,nosuid,nodev,noexec in /etc/fstab
VULN-05Medium (CVSS 5.9)Web Stack Defense

Missing OWASP Security Headers (HSTS, CSP, X-Frame-Options)

Web reverse proxy does not emit Strict-Transport-Security or Content-Security-Policy headers, exposing users to SSL stripping and Clickjacking attacks.

Remediation Blueprint:
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
VULN-06Compliance (CVSS 5.0)CIS Compliance

CIS Benchmark Control 5.2.3: SSH MaxAuthTries Exceeds Threshold (6 > 3)

Default SSH configuration allows up to 6 authentication attempts per connection, violating CIS Benchmark Level 1 control criteria.

Remediation Blueprint:
Set MaxAuthTries 3 in /etc/ssh/sshd_config
