O365 Pentesting Methodology
Our pentesting office 365 approach involves benchmark-based o365 security assessment as well as standard pentest methodology extended to include Microsoft office cloud-specific cyber security risks and compliance center issues in office 365 review. We support industry-leading testing standards and methodologies for o365 pentesting:
Generally, these include checks on the use of higher privilege administrator accounts, use of MFA, password policy, IAM policies, access keys, conditional access policies, credentials, administrator account usage policies and other security features.
Authentication and authorisation problems are prevalent cyber security risks and compliance centre issues that come in an Office 365 review.
This area in pentesting Office 365 involves checks around network security controls such as ingress, egress rulesets, flow logging, traffic restrictions, and least access privileges.
This phase covers API configuration, log file validation, encryption, access checks, and configuration management for account security and monitoring.
The monitoring phase is one of the critical tasks responsible for alerting relevant contacts during an incident. This involves reliance on the logging and related configuration parameters to ensure the right metric filters are in place.
