As organizations continue to embrace cloud computing, cloud access security has become a major concern for several businesses. As a result, Cloud Access Security Brokers have emerged as a critical component of cloud security. By serving as a policy implementation hub, leveraging security types, and implementing them in business security, CASBs are able to provide cloud security systematically.cIn this article, letâ€™s explore the benefits of employing CASB in a business.Â
What is CASB?
A cloud access security broker (CASB) is a security policy enforcement point that aggregates and injects security policies for cloud resources. Essentially, CASBs serve as policy enforcement hubs between cloud service customers and cloud service providers.Â
Even when cloud services are outside of their perimeter and beyond their direct control, organizations are turning to CASB suppliers to address the risks of cloud services, and enforce security rules, and regulations.
How Does CASB work?
By offering data visibility, granular management, and risk assessment capabilities, CASBs have become an essential component of cloud security. There are three pillars of a CASB's operation: discovery, classification, and remediation. Through discovery software, CASBs are able to compile a comprehensive list of cloud services and their users. This information is then used to classify applications based on their purpose, data consumption, and sharing mechanisms.Â
With these insights, CASBs can create rules for user and data access, adhere to security regulations, and ultimately prevent cyber threats, data leakage, and unauthorized access. Plus, CASBs utilize various security protocols, such as single sign-on, authentication, and malware detection, to further enhance cloud security. By offering these capabilities, CASBs provide businesses with a reliable and efficient means of ensuring cloud access security.
Benefits of CASB
Offers Shadow IT Solutions
A CASB solution offers visibility into shadow IT processes. This enables organizations to identify unsafe cloud applications, prevent harmful application usage, and identify users who are most at risk. With a CASB, companies can select cloud applications that comply with laws and regulations like HIPAA, and develop compliance policies and regulations following the workflow. Applications that are deemed hazardous by organizations can be labeled as "unsanctioned apps" and have access to them limited.
Prevent Cyber ThreatsÂ
Cyber threats might be internal or external, real or virtual, so it is important to prevent them. To reduce these risks as effectively as possible, cloud security must be strengthened by utilizing a CASB solution.Â
Insecure data networks are a constant target for anyone attempting to compromise company data. One can easily reduce external and internal dangers by implementing a reliable CASB system. It is possible to manage BYOD access, govern data access within groups, track individuals or groups engaging in illegal activity, monitor users' online activity in real time, and even manage external file sharing over a cloud network.
Prevent Data Leakage
An effective CASB solution needs a dedicated module that works to stop data leakage or Data Loss Prevention (DLP). DLP solutions give the company the ability to strictly regulate and place limitations on user behavior, preventing the possibility of bad intentions carrying out their operation.Â
Limitations may take the shape of time restrictions, device restrictions, access restrictions, geolocation restrictions, etc. As a result, the implementation of a CASB solution improves control over providing permissions to users belonging to various sets within an organization. This DLP manages both stationary and moving data.
