Cloud access security broker

A quick Insight on the utility of cloud access security broker

CASBs are security policy enforcement points that are positioned between cloud service customers and cloud service providers in order to integrate and insert enterprise security policies when cloud-based services are used. You might think of the CASB as a sheriff enforcing the rules set forth by the cloud service providers.

CASB suppliers are increasingly being used by organizations to address cloud service risks, enforce security policies, and comply with regulations, even if the cloud services are outside of the organization’s perimeter and out of their control.

Automated discovery of cloud applications is used by CASBs to detect high-risk applications as well as users that pose a threat. Various security access controls, such as encryption and device profiling, can be enforced by cloud access security brokers. Credential mapping, for example, can be provided if single sign-on isn’t accessible.

Pillars of cloud access security broker (CASB)

Any CASB solution must start with these elements as the cornerstones. To be successful, any program must have all four pillars.

  1. Visibility

Managed and unmanaged cloud services both necessitate visibility and control for businesses. When it comes to cloud services, IT should have the option of saying “yes” or “no” to certain services while still ensuring that the actions and data within such services are protected. Users on managed devices may have access to a sanctioned suite like Microsoft Office 365, but those on unmanaged devices may simply have web-based email. This is possible. A “no sharing outside of the organization” policy could also entail imposing a “no sharing” policy across a certain category of unapproved services.

While a cloud access security broker’s primary focus is on cloud security, they also provide assistance in understanding your cloud spending. It is possible to uncover redundant functionality and license fees by using a CASB to locate all of the cloud services that are currently in use. A CASB can provide essential commercial and financial data, as well as security measures.

  1. Adherence to regulations

When a firm decides to move its data and systems to the cloud, compliance is a crucial factor to consider. Personal and corporate data can be put at risk if these requirements are ignored, which could result in costly and harmful breaches. Health care providers who are concerned about HIPAA or HITECH, retail businesses concerned about PCI, and financial institutions having to comply with FFIEC and FINRA can all turn to cloud access security brokers for help. By adhering to industry-specific data rules, a CASB can protect your business from costly data breaches.

  1. Security of Data

Utilizing cloud DLP detection technologies like document fingerprinting, as well as decreasing the detection surface area using context, is the best way to ensure accuracy (user, location, activity, etc.). The cloud access security broker (CASB) should provide IT the option of transferring suspected violations to their on-premises systems for further investigation when sensitive content is identified in or on its way to the cloud.

A CASB can operate as a gatekeeper to help your firm discover and stop hostile behavior before it gets out of hand, and a deeper investigation of threats helps. CASBs are well-versed in both IT and business operations and use their expertise to help organizations improve their security.

  1. Protection against Potential Threats

Organizations must ensure that their employees do not introduce or propagate cloud malware and risks via vectors such as cloud storage systems and their associated sync clients and services. This means that when an employee attempts to share or upload an infected file over internal and external networks, a threat can be scanned and remedied in real-time. Cloud services and data can also be used to identify compromised accounts by restricting unauthorized user access.

Cloud-based risks and malware can be protected against via CASBs. Static and dynamic malware analysis must be combined to provide sophisticated threat intelligence for your firm. Cloud services may be a source of some hazards, but adequate threat security can insulate you from them.

Utility of CASB

Ensure Proper Use of Resources

CASBs are well-known for their efficacy in uncovering shadow IT practices, but they are equally adept at securing the rest of a company. Control and visibility over your company’s cloud usage can be achieved with a cloud access security broker (CASB). For example, rather than limiting access to a service, CASBs allow you to manage usage based on identity, service, activity, application, and data rather than a one-size-fits-all approach. As an additional option, you can set policies based on service category or risk and choose from actions like blocking, alerting, bypassing, encrypting, quarantining, and coaching. You can also utilize these instances to notify your IT team of any violations of internal policies.

Protection of Data

Prevent the loss of sensitive data across all of your cloud services, not just those you’ve given permission to utilize. DLP can be used to find and safeguard sensitive data in sanctioned cloud services and in transit to or from any cloud service, whether users are on-premises or remote, using a mobile device or logging in via a web browser or entering via a mobile app or sync client. Encryption, tokenization, and upload prevention can all help avoid data loss.

Taking Precautions to Prevent Danger

It is important to be on the lookout for malware and ransomware that can infect your system over the cloud. To get started, make sure that all cloud services, including those with SSL-encrypted connections, are clearly visible. Find out whether any of your users have been hacked by using anomaly detection and threat intelligence. Detect ransomware using a combination of static and dynamic anti-malware detections, as well as machine learning. Finally, use out-of-the-box connectors and procedures to share your discoveries with the rest of your security architecture. Your CASB vendor needs to keep up with the threats that are out there.

Final Words

CASB technology is transforming into something greater than itself as a result of recent and significant cloud migrations.  Because of their capacity to track cloud application usage across several cloud platforms, cloud access security brokers are a valuable asset. Regulated industries, in particular, need to pay attention to this.
