Network Security Testing aims to map all the network devices, finding out loopholes from those various devices including servers, end user systems, wireless devices and exploiting those loopholes in an ethical way so that one can know about how is there infrastructure is designed. Niall Services experienced Network security testing team does all the vulnerability assessment and exploitation part with their bare hands and not simply relying on any automated scanner and thus eliminating zero chances of false positives. To ensure the overall Network security Niall Services will be looking into below two testing methodologies.

Internal Network Security Testing

An Internal Network Security Testing is required by considering a fact that Insiders are the biggest threat to any organization. An Internal Network Security Testing mimics the actions of an actual attacker exploiting weaknesses in network security without the usual dangers. This test examines internal IT systems for any weakness that could be used to disrupt the confidentiality, availability or integrity of the network, thereby allowing the organization to address each weakness.
Niall Services Internal Network Security Test follows documented security testing methodologies which can include:

• Internal Network Scanning
• Port Scanning
• System Fingerprinting
• Services Probing
• Exploit Research
• Manual Vulnerability Testing and Verification
• Manual Configuration Weakness Testing and Verification
• Limited Application Layer Testing
• Firewall and ACL Testing
• Administrator Privileges Escalation Testing
• Password Strength Testing
• Network Equipment Security Controls Testing
• Internal Network Scan for Known Trojans

External Network Security Testing

An External Network Security Testing is required to defend against external attackers. An External Network Security Testing mimics the actions of an actual attacker exploiting weaknesses in the network security without the usual dangers. This test examines external IT systems for any weakness that could be used by an external attacker to disrupt the confidentiality, availability or integrity of the network, thereby allowing the organization to address each weakness.
Niall Services External Security Test follows best practice in penetration testing methodologies which includes:

• Foot printing
• Public Information & Information Leakage
• DNS Analysis & DNS Brute forcing
• Port Scanning
• System Fingerprinting
• Services Probing
• Exploit Research
• Manual Vulnerability Testing and Verification of Identified Vulnerabilities
• Intrusion Detection/Prevention System Testing
• Password Service Strength Testing
• Remediation Retest (optional)
