Cyber Security Testing
Network Penetration Testing
Identify vulnerabilities in your network before they can be exploited by hackers. Network Penetration testing strengthens your infrastructure and safeguards your business.
What Is Network Penetration Testing?
Network Penetration Testing is a comprehensive security evaluation that simulates real-world attacks on your internal and external network infrastructure. The objective is to identify and remediate vulnerabilities before they can be exploited by threat actors.
This testing method replicates the techniques employed by adversaries to reveal weaknesses such as open ports, misconfigured firewalls, unpatched systems, weak authentication, and other critical network security issues.
Common Security Risks in Networks
Exposed Entry Points Across the Network
Open ports and inactive services can offer attackers potential entry points into the network. These services may be outdated, unpatched, or misconfigured, enabling enumeration, exploitation, or lateral movement within internal systems.
What We Test For:
- Unfiltered open TCP/UDP ports
- Legacy or unpatched services
- Exposed admin interfaces
- Unused but active services
- Poorly segmented network zones
Use of Outdated or Unencrypted Communication
Using outdated or insecure network protocols can expose sensitive data and allow attackers to intercept or manipulate traffic. Common examples include transmitting data in plaintext or relying on deprecated encryption standards.
What We Test For:
- Telnet, FTP, and other plaintext protocols
- SSL (vs. modern TLS) usage
- SMBv1 vulnerabilities
- Insecure remote access (e.g., RDP without NLA)
- Weak or missing encryption for internal traffic
Exploitable Components in the Network Stack
Using outdated software across network devices and services introduces known vulnerabilities that attackers can easily exploit. These flaws often have public exploits or metasploit modules available, making them high-risk if unpatched.
What We Test For:
- Services with known CVEs
- Outdated firmware on routers, switches, or firewalls
- Legacy operating systems (e.g., Windows Server 2008)
- Unpatched third-party applications
- Vulnerable open-source tools or packages
Excessive or Inadequate Network Rules
Firewalls and Access Control Lists (ACLs) play a crucial role in controlling traffic flow. When misconfigured, they can expose internal systems or fail to block unauthorised access, creating openings for network compromise.
What We Test For:
- Overly permissive firewall rules
- Inbound access from untrusted networks
- Lack of logging or alerting
- Absence of egress filtering
- Insecure default configurations
