As organisations increasingly rely on Microsoft Entra ID (formerly Azure Active Directory) to manage user identities and access, the potential for security misconfigurations has grown exponentially. If not properly addressed, these can lead to significant security vulnerabilities, putting your entire business at risk.
Major Issues and Their Business Impact
Non-Privileged Users as Owners of Privileged Applications One of the most common misconfigurations is assigning non-administrative users as owners of privileged Entra ID applications. These users, typically not secured as rigorously as their privileged counterparts, can become easy targets for attackers. If compromised, attackers can gain extensive control over critical applications, leading to unauthorised access to sensitive data, disruption of services, and even financial losses.
Unconstrained Permissions in Mail Services Granting Entra ID applications broad permissions, such as Mail.ReadWrite or Mail.Send, without proper constraints can open the door to serious breaches. If an attacker takes control of such an application, they could access or manipulate email communications across the entire organisation, including those of top executives. The consequences could range from leaked confidential information to fraudulent activities conducted in your company’s name.
Overlooked Service Accounts Decommissioning servers without removing associated service accounts is another oversight that can have severe consequences. These dormant accounts often retain elevated privileges and are rarely monitored, making them prime targets for attackers. If exploited, these accounts can provide a backdoor into your organisation’s most sensitive systems, leading to data breaches or other forms of cyberattack.
Ignoring Entra Connect as a Tier Zero Asset Entra Connect, a critical tool for synchronising on-premises and cloud environments, is often not treated with the level of security it requires. Given its access to extensive identity data and control over Active Directory, failing to classify and protect Entra Connect as a Tier Zero asset can allow attackers to compromise your entire IT infrastructure, both on-premises and in the cloud.
Improper Management of AdminSDHolder The AdminSDHolder object, which controls permissions for privileged accounts in Active Directory, is another critical asset that is often mishandled. Attackers who gain control of this object can grant themselves persistent administrative access, undermining the security of your Active Directory environment and potentially leading to a complete takeover of your IT systems.
