Best Cloud Access Security Brokers (CASB)

Cloud Access Security Brokers (CASB) Guide

Cloud access security brokers (CASB) are an important element of a comprehensive cloud security strategy that provides visibility, control, and real-time protection for organizations who use cloud applications. CASBs are designed to help secure organizations’ data stored in the cloud by providing a layer of defense between the cloud environment and an organization’s network. By acting as trust agents between users and providers, CASBs can provide necessary monitoring and control over the deployment of cloud applications without sacrificing user productivity or performance.

In order for CASBs to be effective, organizations must configure their systems to monitor all interactions with the cloud platform. This includes all traffic that goes into or out of the cloud environment, including web requests from employees as well as any services running in the cloud environment. A key part of this configuration involves setting up authentication protocols for each user, which involve verifying identity through methods such as passwords or two-factor authentication (2FA). Once authenticated, access control policies can be established to limit which applications users can access within the system, ensuring only authorized users have access to sensitive data.

Another significant role played by CASBs is enforcing compliance standards throughout the company's security architecture. This is often done by integrating with existing organizational workflows so they can continuously analyze usage logs across multiple services and devices in order to detect anomalous behavior that may indicate malicious activity such as unauthorized downloads or inappropriate sharing of information with external recipients outside of approved sanctioned channels. Moreover, CASB solutions offer additional layers of security such as data loss prevention (DLP), anomaly detection mechanisms, risk scoring capabilities based on user behavior analytics (UBA), privileged account management tools to help manage administrative accounts with additional oversight requirements per various US government regulations such as HIPAA & PCI DSS., along with malware scanning capabilities that enable it to identify known threats from malware before they have an opportunity to cause harm.

Overall, utilizing a robust Cloud Access Security Broker solution helps organizations protect their resources while meeting their security goals both inside and outside the corporate network so they don't lose out on any opportunities associated with leveraging a growing number of available software-as-a-service offerings while reducing potential risks caused by unauthorized access or malicious actors seeking out vulnerable points within system infrastructure architectures for exploitation.

Features Provided by Cloud Access Security Brokers (CASB)

• Visibility and Control – CASBs provide visibility into a company’s cloud usage, including users, applications, and data. They also give administrators the ability to control access to those resources. This allows for granular security policies that can be easily configured and enforced.
• Data Loss Prevention (DLP) – CASBs provide DLP capabilities that allow companies to detect, monitor, and protect sensitive data stored in the cloud. These capabilities are critical in helping an organization comply with data privacy regulations such as GDPR or CCPA.
• User Activity Monitoring – CASB solutions include the ability to monitor user activity within the cloud environment in real-time. This includes logging activities such as file uploads/downloads, API calls, authentication attempts and more. This monitoring capability helps uncover malicious activities quickly and prevent further damage from occurring.
• Threat Intelligence – CASB solutions also feature threat detection capabilities designed to identify potential threats within a cloud environment before they cause damage or disrupt operations. Additionally, many solutions support automated responses when a threat is detected, mitigating potential harm quickly and efficiently.
• Cloud App Security – CASBs offer specialized security features tailored for popular cloud applications such as Salesforce or Office 365. These features include granular access control policies for users and files as well as encryption for stored data at rest or in transit over networks such as the internet.
• Endpoint Protection – Some CASB solutions include endpoint security capabilities that allow organizations to secure devices connected to their cloud environment against malware and other cyber threats via deep packet inspections on every communication channel established by each device connected to the network.
• Regulatory Compliance – CASBs enable organizations to meet compliance requirements for various data privacy regulations and standards, including GDPR, CCPA, and PCI-DSS. The solutions can be tailored to meet the specific requirements of each regulation, providing peace of mind that an organization’s cloud environment is compliant.

Types of Cloud Access Security Brokers (CASB)

• API Access Brokers: API access brokers are CASB solutions that provide secure access to cloud-based applications via APIs. They manage authorization, authentication and access control to ensure that users only have the necessary privileges to do their jobs. These brokers also monitor user activity and analyze usage data for anomalies or threats.
• Network Layer Brokers: Network layer brokers are designed to secure communication between enterprise networks and cloud environments. They identify and block malicious traffic from entering the cloud environment, as well as prevent unauthorized data exfiltration from leaving it. These CASBs also provide network segmentation and granular control of user access to cloud resources.
• Data Loss Prevention (DLP) Brokers: DLP brokers are CASBs that protect sensitive data by monitoring its movement in and out of the cloud environment. They detect potentially sensitive data, such as credit card numbers or Social Security numbers, based on predetermined criteria and take action according to configured policies – they can trigger an alert or even block the transmission of such data altogether.
• Encryption/Tokenization Brokers: These CASBs use encryption or tokenization technologies to protect confidential information stored in a cloud environment without compromising its usability in applications that need it for processing tasks. For example, medical records could be encrypted before being stored in a healthcare provider’s database so that only authorized personnel with the correct credentials can view them but still process them for diagnostic purposes if needed.
• Identity & Access Management (IAM) Brokers: IAM brokers enable organizations to effectively manage permissions and roles across multiple cloud services from a single console; this makes it easier for companies to audit users’ activities within their organization’s own systems as well as within third-party clouds they may be using for various services like storage or software development platforms.. Additionally, IAM brokers often leverage multi-factor authentication protocols such as two-factor authentication (2FA) help reduce risk associated with malicious actors gaining unauthorized access through stolen credentials or other means.
