A CASB discovers shadow IT by analyzing network traffic and logs to identify unauthorized cloud services and apps used within an organization. It scans and audits the traffic between users and cloud services to detect unapproved applications. By integrating with existing network security appliances and through API connections with sanctioned cloud services, CASBs provide visibility into cloud usage patterns, highlighting applications that have not been vetted or approved by IT. This allows organizations to monitor for potentially risky services and enforce policies to manage or restrict the use of unsanctioned apps, helping to control shadow IT and mitigate associated security risks.

A Cloud Access Security Broker analyzes shadow IT by evaluating the compliance of discovered apps with organizational standards, and analyzing their usage, including the number of active users and traffic generated. It can identify specific user groups and their activities, data access, and resource usage. If a risky app is detected, the CASB can suggest safer alternatives that comply with the organization's policies.

CASBs employ robust mechanisms to analyze shadow IT within an organization. This analysis involves evaluating the risk associated with the discovered shadow IT instances and understanding the potential impact on data security. One key aspect of CASB analysis is the assessment of security policies. CASBs scrutinize the security configurations and policies of unauthorized cloud services to identify vulnerabilities or non-compliance with organizational security standards. This enables the system to provide insights into potential weaknesses and aids in formulating corrective actions. Furthermore, CASBs often utilize advanced threat intelligence to analyze the security posture of shadow IT instances.

CASBs inspect network traffic to identify patterns and connections to external cloud services. By analyzing logs and network flows, the CASB can detect traffic going to cloud applications that may not be officially sanctioned by the organization.

A CASB analyzes shadow IT by collecting and aggregating logs from various data sources such as firewalls, secure web gateways, and SIEM systems. It then uses these logs to identify and catalog cloud applications being accessed across the organization. By applying analytics and machine learning, it assesses the risk level of these services based on factors like service popularity, security measures, and compliance with data privacy standards. The CASB provides insights into the volume of data transferred, user activity patterns, and potential security threats or compliance issues associated with these unsanctioned applications.

Once you start using CASB to analyze and classify data, you should also consider creating security policies that govern cloud access and data management. This is especially important when it comes to protecting sensitive information and complying with regulatory requirements. CASB can automatically enforce these policies in real time, blocking unwanted or suspicious activity and alerting you to potential threats. This not only prevents data leakage, but also greatly simplifies the compliance management process, making it more transparent and controllable.

A Cloud Access Security Broker manages shadow IT by classifying apps using custom tags, allowing for specific monitoring.
