Network Penetration Testing

External penetration testing aims to simulate an attack from outside an organization’s network to identify vulnerabilities and weaknesses in its external defences. This process is structured to evaluate the security of internet-facing systems and applications. A QSS Security engineer attempts to gather sensitive information through open-source intelligence (OSINT), including employee information, historical breached passwords, and more that can be leveraged against external systems to gain internal network access.

Our Methodology adopt during testing

All testing performed is based on the NIST SP 800-115 Technical Guide to Information Security Testing and Assessment, OWASP Testing Guide (v4), and customized testing frameworks.

Activities performed during external penetration testing include, but are not limited to:

  • Vulnerability scanning and exploitation
  • Social media intelligence gathering
  • Username and account enumeration
  • Breached credential intelligence gathering
  • Service, port, and website enumeration
  • Enumerating third parties for data leaks (S3 Buckets, GitHub, etc.)
  • Attacking login portals (Website, O365, VPN, etc.)
  • Multi-Factor Authentication (MFA) bypassing
  • Other testing depending on specific customer content and footprint
Frequently Asked Questions

Answers to Your Questions

Penetration testing helps identify security weaknesses that could be exploited by attackers. It enables you to address these vulnerabilities, improve your security posture, and protect sensitive data.

It’s recommended to conduct penetration testing at least annually. However, if there are significant changes to your network or applications, or if you’re required to meet compliance regulations, you may need to test more frequently.

A Red Team operates by conducting simulated attacks that mimic tactics, techniques, and procedures used by real adversaries. They use various methods such as phishing, social engineering, and technical exploits to compromise systems.

A Blue Team operates by implementing security measures such as firewalls, intrusion detection systems, and encryption. They also monitor network traffic, analyze security logs, and respond to incidents to protect against and mitigate attacks.

The duration of a penetration test varies based on the scope and complexity of the engagement. It can range from a few days for a small application to several weeks for a large enterprise network.

Penetration tests should be conducted by experienced and certified professionals, such as those with certifications like Certified Ethical Hacker (CEH) or Offensive Security Certified Professional (OSCP).

No, penetration testing cannot guarantee 100% security. It identifies and helps remediate known vulnerabilities but cannot uncover every possible issue or predict future attacks.

Yes, cybersecurity is crucial for any business, regardless of size or industry. Cyber threats can lead to significant financial loss, damage your reputation, and interrupt business operations. At QSS Cyber Security, we help businesses protect their valuable data and digital infrastructure, reducing the risk of cyber attacks and ensuring business continuity.

Common vulnerabilities include SQL Injection, Cross-Site Scripting (XSS), Broken Authentication, Insecure Direct Object References (IDOR), and misconfigured security settings.

Red Teams and Blue Teams often interact in exercises known as "red team-blue team" exercises or "adversarial simulations." The Red Team conducts attacks while the Blue Team defends, providing a realistic and controlled environment to test and improve defenses.

QSS was founded by a group of hackers with a passion for security. QSS is just a name, but security researcher and providing expert pentesting to clients is what we love to do!

Client data protection is our priority. We use non-destructive methods during our assessments and maintain strict confidentiality.

The cost of a penetration test varies based on the scope, complexity, and size of the engagement. It’s best to get a customized quote from a provider based on your specific needs.

A cybersecurity audit is an assessment of your cybersecurity policies and procedures. QSS helps support your audit initiatives by providing robust penetration testing services.

A Blue Team addresses findings by implementing the recommended fixes, enhancing security measures, and improving incident response processes based on the Red Team's feedback.

A vulnerability assessment identifies potential weaknesses without attempting to exploit them, while a penetration test actively exploits vulnerabilities to assess their impact and security posture.

Yes, we provide detailed reports post-assessment and offer consultation sessions to address any queries or concerns you might have. Remediation testing is always included.
