Challenges
During the assessment, CyberGlobal carried out a structured series of tests designed to uncover real risks within the client’s environment. Our team began with external and internal network enumeration, followed by service and vulnerability scanning across all assigned IP ranges.
Every identified issue was manually verified and, where appropriate, safely exploited to demonstrate impact. Active Directory enumeration and credential-based testing offered deeper insight into internal systems.
Specific tools were used to guarantee accuracy and depth, including:
- Nessus
- Nmap
- Burp Suite
- BloodHound
- Certipy
In total, around 60 servers and applications were tested. The results revealed several medium-level risks, including Active Directory misconfigurations and missing SMB signing requirements, alongside a set of low and informational vulnerabilities documented in detail.
Solutions
Following the assessment, CyberGlobal developed a set of targeted strategies to strengthen the client’s security posture and reduce identified risks.
The following steps were taken:
- Enforce SMB signing, making sure that communications across the network cannot be easily manipulated.
- Tailored firewall rules were applied to restrict the external exposure of sensitive services, limiting opportunities for attackers to gain a foothold.
- Hardening Active Directory, introducing stronger authentication methods, auditing permissions, and restricting excessive access rights, all while monitoring for unusual login behavior.
- Weak or outdated encryption algorithms were removed and replaced with modern standards to further protect data integrity.
- On the application side, security headers were introduced to shield web platforms against common exploits.
- Centralized logging and monitoring through a SIEM solution was implemented, providing real-time visibility and quicker detection of suspicious activities across the network.
Results
The security assessment carried out by CyberGlobal highlighted several areas where improvements were needed, both within internal and external networks. Encouragingly, no critical or high-severity issues were detected, showing that the client’s infrastructure already had strong resilience against many common threats.
The findings, however, pointed to medium-level concerns such as:
- Active Directory misconfigurations
- Lack of SMB signing
- Outdated JavaScript libraries
- Missing HTTP headers
- Cryptographic weaknesses
- Various information exposure through web applications
After the client implemented our recommended actions, including system updates, configuration hardening, and the adoption of stronger protocols, the overall residual risk was assessed as medium.
The engagement also underlined several important lessons:
- Active Directory must be continuously monitored
- SMB signing should always be enforced
- Cryptographic standards require ongoing updates
Ultimately, regular penetration testing, proper configuration management, and swift remediation are essential practices for building long-term cyber resilience.
