Network VAPT

DigiFortex: Your Trusted Partner in Network Penetration Testing

In today's digital age, cyber threats are constantly evolving, targeting businesses of all sizes. At DigiFortex, we understand the critical importance of protecting your network, data, and systems. That’s why we specialize in Network Penetration Testing—a proactive way to uncover vulnerabilities in your network before hackers can exploit them.

What is Network Penetration Testing?

Network Penetration Testing, also known as Network Security Testing, is a simulated cyberattack on your network infrastructure aimed at identifying security weaknesses. The process involves assessing your network architecture, devices, servers, firewalls, and other components to find vulnerabilities that a hacker could exploit to gain unauthorized access, steal sensitive information, or disrupt services.

By performing Network Penetration Testing, we can uncover issues such as open ports, misconfigured firewalls, unpatched software, and weak access controls. Once vulnerabilities are identified, we provide actionable recommendations for improving your network's security posture.

   Fulfil requirements for frameworks like ISO 27001, NIST 800-53, SOC 2, PCI DSS, and GDPR.
6. Bolster Business Continuity:
   Minimize the risk of downtime, data breaches, and reputational damage.

Common Vulnerabilities in Network Security

Network Penetration Testing helps identify many common vulnerabilities that could put your business at risk. Some of the most prevalent vulnerabilities we look for include:

1. Unpatched Software:
   Software and firmware on network devices can become vulnerable over time if not updated regularly.
2. Weak Authentication:
   Weak passwords and lack of multi-factor authentication allow attackers to easily compromise user accounts and access sensitive data.
3. Unsecured Ports and Services:
   Open ports and unsecured network services provide attackers with easy entry points into your network.
4. Misconfigured Network Devices:
   Routers, firewalls, and other network devices often have misconfigurations that can lead to unauthorized access.
5. Insecure Protocols:
   Fulfil requirements for frameworks like ISO 27001, NIST 800-53, SOC 2, PCI DSS, and GDPR.
6. Lack of Network Segmentation:
   Without proper segmentation, attackers who gain access to one part of the network can easily move laterally to access other critical systems.

DigiFortex Network Penetration Testing Approach

At DigiFortex, we take a comprehensive approach to Network Penetration Testing, leveraging the latest tools, methodologies, and industry best practices to identify and mitigate risks. Our team of certified security experts follows a structured process to test your network’s security effectively.

1. Reconnaissance and Information Gathering

   The first step in our penetration testing process is to gather as much information as possible about your network. This involves both passive and active techniques, including:

   • Network Scanning: Identifying the devices connected to your network, including routers, servers, workstations, and firewalls.
   • OS Fingerprinting: Determining the operating systems running on your devices to identify potential vulnerabilities specific to those platforms.
   • DNS Interrogation: Gathering DNS records to understand your network structure and identify potential targets.
   • Social Engineering: In some cases, we use controlled social engineering techniques to test your employees’ susceptibility to phishing and other tactics used by attackers to gain access to your network.
2. Vulnerability Scanning

   Once we’ve gathered enough information, we use automated tools and manual techniques to identify vulnerabilities in your network’s infrastructure. Common vulnerabilities include:

   • Open Ports: Unnecessary open ports can provide attackers with an entry point to your network.
   • Weak Passwords: Easily guessable passwords or lack of multi-factor authentication (MFA) can leave accounts exposed.
   • Outdated Software: Unpatched systems and outdated software are prime targets for attackers exploiting known vulnerabilities.
   • Misconfigured Firewalls: Incorrectly configured firewalls can allow unauthorized access to your network.
   • Unsecured Protocols: Using outdated or insecure communication protocols like FTP or Telnet increases the risk of unauthorized access.
3. Exploitation and Attack Simulation

   After identifying vulnerabilities, our next step is to simulate an attack on your network. This is the critical phase where we attempt to exploit vulnerabilities and gain unauthorized access to your network. Some of the techniques we use include:

   • Exploiting Open Ports: We test open ports for weaknesses and attempt to gain access to devices or services running on them.
   • Password Cracking: Using tools like brute-force attacks or dictionary attacks, we attempt to crack weak passwords and gain access to sensitive systems.
   • Privilege Escalation: If we gain access to one part of the network, we attempt to escalate privileges to gain control over critical systems.
   • Denial-of-Service (DoS): We simulate DoS attacks to assess whether your network can withstand traffic spikes or other attacks designed to overwhelm network resources.
4. Post-Exploitation and Lateral Movement

   After gaining access to your network, we simulate the behavior of an attacker attempting to move laterally within your network. This helps us identify potential paths an attacker might take to access additional systems, data, or credentials. Key activities during this phase include:

   • Accessing Sensitive Data: We test the network’s ability to protect sensitive data and determine if attackers can move laterally to access confidential business information.
   • Privilege Escalation: We attempt to elevate our access level to gain control over higher-value systems and servers.
   • Persistence: We assess how an attacker could maintain access to your network over time, even if they were detected initially.
5. Reporting and Remediation

   After completing the penetration testing process, we provide you with a detailed report outlining all identified vulnerabilities, how we exploited them, and the risks associated with each issue. The report includes:

   • Vulnerability Summary: A description of each vulnerability discovered, including its severity and potential impact.
   • Attack Scenarios: Detailed scenarios of how the vulnerabilities were exploited and the data or systems compromised.
   • Recommendations: Actionable steps to remediate each vulnerability and improve your network security, such as updating software, strengthening authentication processes, or reconfiguring firewalls
   • Remediation Recommendations
