Despite major investments in cybersecurity, organizations continue to face breaches. Most security mechanisms implemented guard against threats such as password theft. However, there is a growing concern with the unchecked expansion of user access, permissions, and tokens across apps, clouds, and systems.

This growing challenge is known as authorization sprawl, and it is becoming one of the most dangerous and least visible threats in modern enterprise security.

According to insights from the SANS keynote at the RSAC 2025 Conference, attackers are increasingly exploiting this sprawl to gain legitimate, persistent access that bypasses multifactor authentication (MFA), security information and event management (SIEM) alerts, and endpoint detection and response (EDR) visibility altogether.

What is Authorization Sprawl?

Authorization sprawl occurs when access permissions multiply uncontrollably across systems, users, and applications. Every time a team or department adds a new SaaS integration, service account, or API key, another layer of permission is introduced.

In an attempt to make access to multiple applications easy, users also have single sign-on (SSO), designed to help log in once and access multiple applications securely. Here, users are granted access to several connected systems through SSO, adding to the authorization sprawl problem.

Over time, all these factors create a complex ecosystem that even security teams have a hard time tracing who can access what.

Unlike authentication, which verifies who someone is, authorization determines what one can do. When permissions expand without review, attackers take advantage of forgotten tokens, dormant accounts, or outdated roles to move freely inside systems.

Why Traditional Defenses Miss It

Most defenses focus on identity verification, such as MFA, conditional access, and endpoint protection. But once a user is authenticated, there is no monitoring. This is the blind spot that attackers exploit. Instead of breaking in, they log in using legitimate session tokens, application programming interface (API) keys, or open authorization (OAuth) grants.

The misuse of valid credentials or access tokens enables cloud-related breaches. These attacks bypass traditional detection tools because they appear to be normal activity by authorized users.

A recent incident involving Salesloft’s Drift application highlights how damaging authorization sprawl can be. Drift, an AI chatbot often integrated with Salesforce, was exploited after attackers gained access to Salesloft’s GitHub account and later its AWS environment. From there, they stole OAuth tokens and authentication credentials, exposing Salesforce data from potentially hundreds of organizations. This incident is an example of how interconnected SaaS systems and unchecked authorization links can create a cascading breach effect, where one weak point leads to multiple breaches across services.

The Business Impact of Authorization Sprawl

Aside from increasing technical risk, authorization sprawl erodes compliance, governance, and trust.

1. Regulatory Exposure – Frameworks like GDPR, SOC 2, and HIPAA require strict access control and auditability. Untracked permissions make demonstrating compliance nearly impossible.
2. Operational Risk – An overprivileged account can unintentionally leak data, delete configurations, or expose APIs.
3. False Sense of Security – Zero Trust frameworks often stop at identity verification. Failing to continuously validate authorization is equivalent to protecting the front door while leaving internal doors wide open.

How to Fix Authorization Sprawl

Luckily, solving this problem does not require removing existing security controls but rather extending visibility and discipline into authorization.

1. Conduct Regular Access Audits – Map users, roles, and permissions across your environment. Be sure to look for redundant privileges, dormant accounts, and orphaned API keys. Use tools that help visualize hidden paths and privilege escalation routes.
2. Implement Structured Access Control – Use frameworks like role-based access control (RBAC) or attribute-based access control (ABAC). Standardizing roles ensures fewer exceptions and easier auditing.
3. Automate Reviews and Revocations – Integrate identity and access management (IAM) with HR systems so access automatically changes when employees leave or change roles. This helps eliminate the temporary access that never gets removed.
4. Shorten Token Lifetimes and Rotate Credentials – Session tokens and personal access tokens (PATs) should have an expiration period, such as 30 to 90 days. Using automated key rotation policies will help prevent long-lived access tokens from becoming backdoors.
5. Enforce the Principle of Least Privilege – Grant users and systems only the minimum access needed.
6. Extend Zero Trust to Authorization – Verification shouldn’t end with login. Apply continuous authorization checks.

Conclusion

As cloud ecosystems, APIs, and integrations continue to multiply, authorization complexity will grow exponentially. Businesses that invest in mapping and controlling authorization sprawl will stay ahead of both attackers and regulators. In cybersecurity, visibility equals control, and this begins with knowing exactly who can do what.

As organizations invest heavily in next-gen firewalls, AI detection, and threat intelligence, grave cyberattacks have been reported as a result of overlooked misconfigurations. According to the latest statistics, about 23 percent of cloud security incidents are directly connected to misconfigurations. These missteps create easy entry points for cybercriminals that may lead to data breaches, ransomware demands, and financial loss.

What are Misconfigurations?

Misconfigurations are overlooked errors in system setups that create vulnerabilities without the need for hackers to apply advanced hacking techniques. These silent threats are human-driven oversights when configuring software, hardware, or cloud services. Good examples include improperly set permissions in cloud storage, insecure API keys left in code repositories, inadequate security monitoring, and unsecured access points like IoT devices with default passwords.

These issues arise from human error, which accounts for 82 percent of misconfigurations. This is also compounded by today’s cloud era, where businesses depend on cloud platforms, software as a service stacks (SaaS), and AI-driven infrastructure. Many organizations now use multiple providers, and this makes configurations challenging. Rushed deployment also adds to the misconfiguration problem, especially when a thorough audit is not conducted. Unlike malware or phishing scams, misconfigurations remain undetected until exploited.

2025’s Worst Cyberattacks Fueled by Misconfigurations

This year alone, there has been a surge in incidents related to misconfiguration, which is alarming. There were more than 9.5 million cyberattacks in the first half of the year. A good example is the Coinbase breach of May 2025, in which data from more than 70,000 customer records was stolen. This breach is attributed to insider threats exploiting misconfigured permissions.

Recently, cybersecurity researchers revealed a botnet campaign that exploited misconfigured DNS sender policy framework (SPF) records across 20,000 domains and compromised more than 13,000 MikroTik routers. This enabled large-scale spam and spoofing attacks.

In many regions, misconfigured VPN gateways and remote access tools have also contributed to ransomware campaigns. This is through attackers bypassing perimeter defenses by exploiting a misconfigured VPN portal.

IoT weaknesses have also seen entire networks of smart devices compromised, simply because administrators did not change the default login credentials. The entry points ranged from security cameras to industrial sensors, allowing attackers to access more sensitive corporate systems.

Why Organizations Keep Making the Same Mistakes

• Talent shortage – Many IT teams are stretched and lack sufficient experts to catch every misstep.
• False confidence in automation – While automated tools are a great help, they are not foolproof. Overreliance on these tools and having a set-and-forget mindset can leave room for security breaches.
• Velocity over security – This happens when rapid delivery of product features overshadows the slower discipline of security reviews.
• Siloed responsibility – In many organizations, security is delegated to a separate team instead of being embedded across different units like the development, operations, and business units.
• Awareness gap – Many teams underestimate how a single overlooked setting, like an open test environment, can escalate into a full-scale breach.

Prevention Strategies and Best Practices

Fortunately, misconfigurations are one of the preventable causes of security breaches. Preventing misconfigurations requires proactive measures that include:

• Continuous auditing and testing – It is crucial to ensure regular audits and testing of automated tools for configuration management to detect and reduce the window of exposure.
• Adopt zero-trust models – No device or user should be trusted by default; grant only minimum access where required.
• Strengthen access controls – Always change default device credentials, partition networks, and enforce MFA across all accounts.
• Automated detection tools – Use cloud security posture management, compliance-as-code, and drift detection to catch misconfigurations in real time.
• Cross-functional training and culture – Employee training is vital, as human error accounts for 82 percent of incidents. Security literacy should extend to both technical and non-technical teams.
• Follow industry guidelines – Align with recognized security frameworks (NIST, ISO, CIS) and CISA’s published guidance on the Top Ten Cybersecurity Misconfigurations. For example, avoid using default configurations, enforce patch management, and properly segment networks.
• Incident response readiness – Have a well-drilled response playbook to ensure minor disruption in case the defenses fail.

Conclusion

Simple misconfiguration remains a silent enabler of devastating cyberattacks through avoidable errors. Business owners must prioritize configuration hygiene to build resilient digital infrastructures and protect against future threats.

It is a clear lesson that cybersecurity doesn’t always depend on battling sophisticated hackers but rather ensuring they don’t get an easy way in.
