The right CASB solution can help your business understand what data moves to and from your cloud environments. Given the growth of BYOD and unsanctioned cloud usage, this type of monitoring is key for enterprises.
Look for a CASB that offers auto-discovery, threat assessment and monitoring, security policies and tools, data loss prevention capabilities, and encryption and tokenization tools.
When selecting a CASB solution, IT teams need to consider the cost. During the trial and evaluation period, they should also evaluate functionalities such as authentication, authorization and alerts. They should also determine whether the CASB will integrate with their existing identity-as-a-service (IDaaS) and single sign-on (SSO) tools. Additionally, they should consider the CASB’s role in detecting and preventing threats.
With the rise of remote work and bring-your-own-device policies, enterprises need a better way to protect their data. CASBs can help secure sensitive information in the cloud by monitoring and enforcing data security policies. These solutions also detect unsanctioned employee apps, known as Shadow IT, and allow enterprises to take a more granular approach to security.
CASBs provide visibility into cloud usage by analyzing and detecting user behavior. Using auto-discovery, they compile a list of all third-party cloud services and those using them. In addition, CASBs can see anomalous patterns and use machine learning-based user and entity behavioral analytics (UEBA) to identify suspicious activity.
CASBs can detect and block malware that uses the cloud to hide on the network. They can also stop the unauthorized sharing of files and monitor data transfers to external devices. In addition, CASBs can prevent the loss of sensitive data by scanning the contents of emails and messages. They can also help detect and block ransomware by analyzing encrypted file content.
The cloud has increased the ease of storing data, making this information more vulnerable to threats and malicious activities. A CASB solution allows organizations to monitor and control their cloud environments and prevent data loss. This can be done through various features, including threat detection and management, encryption, compliance enforcement and monitoring, and visibility.
Originally, CASB solutions were used to stem the flow of shadow IT and decrease the impact of cyberattacks, but they’ve evolved into much more. They now provide visibility into the use of cloud applications across all networks, including internal and external ones, and help companies comply with regulatory and security policies. Additionally, CASBs can protect against the unauthorized use of cloud services and allow administrators to revoke access to those applications.
When evaluating a CASB solution, it’s important to consider your organization’s specific needs and how they will be addressed. You should assess the vendor environment and leverage media coverage, and analyst reports to identify vendors with a strong track record of preventing breaches and remediating them quickly and effectively. It’s also a good idea to conduct a trial of the solution. This will allow your organization to test the functionality of the CASB to ensure it meets your requirements before making a purchase.
As businesses deploy more cloud-based applications for collaboration and remote work, CASB solutions become essential to secure this trend. But a CASB is only part of the overall security strategy enterprises should employ to ensure defense from endpoint to cloud. Enterprises should also consider deploying a secure web gateway (SWG) to help safeguard internet usage and a device data loss prevention solution to prevent the loss of intellectual property and sensitive corporate data.
Rather than taking a sledgehammer approach of blocking all services or only those sanctioned, a CASB should provide granular controls to enable productivity-enhancing and cost-effective cloud apps safely. These capabilities should include auto-discovery and listing of third-party cloud apps, account management to detect unauthorized use or compromised accounts, and threat protection for ransomware and malware.
The best CASB solutions operate in the data path to control traffic between an endpoint and the cloud app. They can be deployed via proxies (forward or reverse), APIs, or both (a combination of the two called multimode).
Evaluate the vendor landscape to identify CASB providers that support your business’ specific use cases and security requirements. Consider leveraging industry media coverage and analyst reports to narrow the list. Finally, conduct a trial to test the ability of the solution to meet your unique needs. Then, select a CASB that can address your business’s security needs and fit within its budget.
When choosing a CASB, you’ll want to consider its integrations. These are critical for deploying and monitoring the security solution. For example, it’s important to determine if you want the answer to collect and analyze logs or perform forward proxy. Additionally, you’ll need to know if the solution offers granular and risk-based authentication and encryption.
A CASB can help organizations monitor cloud usage and control data movement to ensure compliance with company policy. A CASB can also identify misconfigurations that can lead to a data breach and alert administrators when these issues are detected. A CASB may include features such as file loss protection and endpoint visibility, depending on an organization’s needs.
The shift to a cloud-based business model has made it exponentially more difficult for IT teams to maintain visibility regarding how their corporate data is used. CASBs can help by ingesting logs, detecting cloud applications and environments, and identifying users using unapproved software. This allows IT to take the necessary actions to comply with regulations such as GDPR, HIPAA and PCI DSS. It can also reduce the risk of shadow IT and unauthorized apps by detecting suspicious behavior, such as login attempts from unknown devices or locations. Finally, it can detect malware and ransomware by utilizing a combination of anomaly detection, threat intelligence sources and machine learning to identify suspicious activity and arm the rest of the security infrastructure with those findings.
