External Network Penetration Testing
An external network pen test is designed to evaluate how successfully perimeter security measures deter and detect assaults as well as find flaws in internet-facing assets like web, mail, and exposed infrastructure assets.
Customers, regulators, and insurers essentially all need external penetration testing services to make sure the perimeter is a dependable defense against attackers in light of the rise in data breaches and attacks on organizations of all kinds. Annual or more frequent testing is mandated by compliance standards like PCI DSS and includes different types of assessments and external pen tests.
Exploitable vulnerabilities can give an attacker access to sensitive information and the network of a company. External network penetration testing is used to proactively verify the efficiency of security controls and thus reveals these vulnerabilities related to it, allowing businesses to put preventive measures in place to reduce risk.
Internal Network Penetration Testing
Internal systems cannot be completely protected by the perimeter. There is only one way in for an intruder. Once within, a weak internal network can be used to quickly advance in rank.
Therefore, it is essential to evaluate network security measures using internal penetration testing tools and techniques to stop malevolent users from gaining unauthorized access to protected data. Attacks from within have serious consequences and frequently go unnoticed for prolonged periods of time. An internal network penetration test can simulate insider threats, such as staff members acting maliciously on purpose or accidentally.
When vital internal assets are subject to an internal pen test, vulnerabilities are found, the potential consequences of an exploit are shown, and modifications that may be made to reduce the risk are clearly indicated.
Segmentation Policy refers to the process of segmenting a network and creating firewall or routing policies to enforce the boundaries between those segments. The segmentation policy is the benchmark for what kind of access is allowed to and from the network. Any results from segmentation testing will be compared to it to make sure everything is operating as intended.
Segmentation penetration testing is a thorough and effective testing methodology that supports all segmentation techniques, including physical segmentation, Layer 2 and Layer 3 security controls, micro-segmentation, micro segmentation with SDN and Zero Trust, hypervisor and cloud security controls, without being limited to conventional firewall rule-based isolation.
