Cloud access security brokers (CASBs) have emerged as vital security checkpoints between cloud-based apps and users. They oversee and implement all security rules and procedures, including encryption, alarms, and authentication.
A CASB protects the organization by combining preventive, monitoring, and mitigation techniques. The CASB can also warn managers of potentially risky behavior, stop malware installations or other hazards, and spot potential compliance issues in addition to monitoring user behavior.
The organization’s proxy logs or firewall may also be examined by the CASB in order to gain a deeper understanding of cloud usage and spot unusual behavior. Given the prevalence of cloud services and the rising popularity of remote work, a CASB solution is very beneficial.
Why Employ CASBs?
CASBs are essential for organizations that use cloud services, particularly SaaS or storage. By using the appropriate CASB, companies can safeguard their data as it travels between their network and their cloud-based service providers. There are several reasons why organizations should employ CASBs:
- Manage Use
CASBs are effective in identifying shadow IT actions and are knowledgeable about additional organizational security. By providing visibility and control over cloud usage, CASBs allow organizations to control use based on activity, identity, data, and application.
Instead of taking a blanket approach and barring all services, organizations can set policies built on the type of risk or service and choose from a range of enforcement options.
- Protect Data
Sensitive data should be safeguarded and kept from being lost across an organization’s environment’s cloud services. By using sophisticated business DLP, organizations can find and safeguard private data in authorized cloud services as well as in transit across cloud services. Tokenization, encryption, or upload prevention can all be used to prevent data loss.
- Guard against Cyberattacks
Organizations can protect themselves from cloud-based risks like ransomware and malware by using CASBs. By using threat intelligence sources like which of their users’ accounts have been compromised and anomaly detection, organizations can detect and prevent threats.
Organizations can also add machine learning (ML) to identify ransomware and static and dynamic anti-malware detections. Plus, they can utilize workflows and integrations to equip the rest of their security architecture with the results.
Three Things to Think About While Selecting A CASB
- Is It Fitting?
Enterprises should establish their unique CASB uses before choosing a CASB and specifically search for a solution that addresses their objectives. Companies should do thorough POCs, check with cybersecurity experts, or conduct in-depth reference conversations with other businesses of comparable sizes and needs in order to assure the best fit.
- Does It Expand and Modify to Meet Your Needs?
The danger landscape will expand along with the use of enterprise clouds. You can keep your security policies and cloud compliance current and generally gain new feature access sooner by collaborating with the correct CASB vendor.
- Protect IaaS?
SaaS security is crucial, but IaaS (Infrastructure as a Service) environments also need to be safeguarded for complete company security. The CASB should secure IaaS activity and configurations for businesses that need this capacity, but it should also protect its consumers by enforcing threat prevention, activity monitoring, and DLP restrictions.
