Azure provides a robust set of tools to prevent and respond to breaches.
Azure Security Center is a unified security management system that helps detect and prevent threats in real-time. It includes threat intelligence and analytics to identify potential vulnerabilities.
Azure Active Directory (Azure AD) is a cloud-based identity and access management solution that helps protect your Azure resources from unauthorized access. Azure AD provides multi-factor authentication, conditional access, and identity protection.
Azure AD Identity Protection is a feature that helps protect your identities from being compromised by detecting and alerting on suspicious sign-ins.
Azure Breach Risks
Successful initial access to an Azure account can lead to a sequence of unauthorized post-compromise activities.
Attackers often register their own MFA methods to maintain persistent access, choosing authenticator apps with notification and code in most instances.
Data exfiltration is a common risk, with attackers accessing and downloading sensitive files, including financial assets, internal security protocols, and user credentials.
Attackers leverage mailbox access for internal and external phishing, conducting lateral movement within impacted organizations and targeting specific user accounts with personalized phishing threats.
Financial fraud is also a risk, with attackers dispatching internal email messages to target Human Resources and Financial departments within affected organizations.
Attackers create dedicated obfuscation rules to cover their tracks and erase all evidence of malicious activity from victims’ mailboxes.
Here are some examples of post-compromise activities:
- Data exfiltration
- Internal and external phishing
- Financial fraud
- Mailbox rules creation
Mitigation and Prevention
To mitigate and prevent Azure breaches, it's essential to understand the current cyber threats to all public and private sector organizations. Monitoring for specific user agent strings and source domains in your organization's logs can help detect and mitigate potential threats.
Here are some key measures to take:
- Monitor for specific user agent strings and source domains in your organization's logs.
- Enforce immediate change of credentials for compromised and targeted users.
- Employ auto-remediation policies to reduce attackers' dwell time and minimize potential damages.
Implementing these measures will help identify initial threat vectors, such as email threats, brute-force attacks, and password-spraying attempts, and reduce the risk of account takeover (ATO) and unauthorized access to sensitive resources.
Recommendations
Human error is a significant contributor to cloud security vulnerabilities, with 82% of data breaches resulting from account takeover attacks, credential theft, or phishing.
To mitigate these risks, it's essential to monitor your organization's logs for specific user agent strings and source domains to detect potential threats.
Enforce immediate changes of credentials for compromised and targeted users, and require periodic password changes for all users.
This can help reduce the likelihood of unauthorized access to sensitive resources.
You can also employ auto-remediation policies to reduce attackers' dwell time and minimize potential damages.
Here are some key measures to bolster your organization's defense against cloud security attacks:
By implementing these measures, you can significantly reduce the risk of cloud security attacks and protect your organization's sensitive resources.
Incorrect Configurations
Misconfigurations are the primary risk for businesses using the cloud.
Insecure data backups are a major concern, as they leave sensitive information vulnerable to unauthorized access.
Missing logs make it difficult to track and detect security breaches, allowing them to go unnoticed for extended periods.
Lack of monitoring also plays a significant role, as it prevents businesses from quickly responding to potential threats.
Incorrect configurations can have serious consequences, including data breaches, financial losses, and reputational damage.

Digital Transformation Security
Companies often struggle to secure their Azure environments due to a lack of expertise. This can lead to significant financial losses and reputational damage.
A cloud breach can cost an average of $4.35 million in lost revenue. This is a staggering amount that could have been avoided with proper security measures in place.
Most companies rely on Azure to drive their digital transformations, but they often don't have the necessary expertise to secure their environments. This is a major concern, especially when it comes to public cloud security.
Reports show that a data breach in the public cloud can lead to lost trust, productivity, and time. These are all valuable assets that can be difficult to recover once they're lost.
Armor can help mitigate these risks and others, giving companies the peace of mind they need to focus on their digital transformations.
