Every cloud application increases an organization's attack surface and opens new routes for hackers to breach it. IT teams require a security solution that offers visibility and control over sanctioned and unsanctioned cloud apps to stay protected against this growing risk.
Cloud environments can be vulnerable to misconfiguration, weak security measures, unsecured APIs, and unpatched software. Protecting them with strong access controls, log and monitoring features, encryption in transit and at rest, and zero-trust policies will provide some form of defense against these risks.
Cloud Auditing and logging
With multi-cloud environments becoming the norm, IT teams must be able to effectively monitor and track an inventory of cloud applications and workloads. Unfortunately, many security solutions focus on monitoring only specific platform services - creating blind spots where malicious or unauthorized activities may take place. At the same time, superior cloud app security solutions enable IT departments to see the big picture allowing them to detect and prevent most threats.
Account Hijacking: Poor passwords and data breaches give attackers entry to cloud applications, turning them into dangerous attack vectors. Once in, they can gain full control over the system with these credentials and take full control.
Data Sharing: By permitting users to share data across platforms, sensitive information could become accessible to unauthorized or malicious third parties who could exploit it for their gain - potentially leading to threats like phishing attacks and ransomware attacks.
Unsecure: APIs offer hackers easy entry into an organization's systems, making them a favorite target. Unsafe APIs can easily be exploited by bots or automated attacks which use botnets to launch malicious commands, exploit vulnerabilities or cause denial of service attacks.
Misconfiguration: Poor configuration of cloud computing systems can expose sensitive information to hackers and compromise its integrity and security, jeopardizing a company's infrastructure, such as data centers, network policies, and access controls.
IT departments must implement robust security solutions such as firewalls to safeguard their networks and applications from phishing and malware attacks.Compliance: Companies must abide by certain standards and regulatory compliance requirements, including GDPR (regulatory compliance for personal data privacy) and PCI DSS (credit card data security standards). Any company failing to do so risks losing customers and incurring severe financial repercussions.
Cloud Confidentiality
Cloud applications are hosted by third parties, meaning your data does not belong solely to your organization and could be accessed by unintended third parties without your knowledge or consent. Therefore, it's imperative to implement robust cloud application security measures to protect sensitive information against unwarranted access or theft.
At this point, encryption becomes crucial. Many cloud service providers offer built-in mechanisms to encrypt data at infrastructure and database levels for added protection so only authorized users can access it.
Another factor worth considering in cloud security is the "shared responsibility model." Responsibility for protecting cloud applications often rests between the service provider and the customer, which may create confusion about its responsibility. Your team should understand this distinction between theirs and that of service providers as it pertains to protecting assets within your cloud environment.
Cloud computing's biggest benefit lies in its ability to share data across departments securely, but that can be challenging if your security architecture is insufficient. If inadequate security measures exist within an organization, they could expose it to risks like account hijacking and credential exposure allowing attackers to gain entry to vital systems.
At its core, cloud security breaches can result in revenue loss and reputation erosion for your business. They also increase legal risks as customers may abandon you for another company. Furthermore, inadequate cloud security measures open your organization to denial of service attacks, allowing attackers to inundate websites or cloud applications with service requests and leading them to slow down or shut down.
To protect your organization against these threats, it is critical that a cloud application security solution work as an integral component within each of your cloud apps. To achieve this goal, integration must occur on an API protocol level between each cloud app and cloud application security solutions - unlike traditional point devices like firewalls and IPS/IDS that work as discrete point devices, cloud application security platforms become seamlessly part of each app so any changes in API are instantly identified and mitigated upon detection.
Cloud Access controls
Access controls in Cloud Application Security ensure that only authorized users can access sensitive data, applications, and services. They identify individuals or entities, verify if they claim they are who they say they are, and approve or deny levels of access and actions associated with their username. They can be implemented using directory services, protocols, or software such as Lightweight Directory Access Protocol and Security Assertion Markup Language that authenticate and authorize computer resources such as distributed applications or web servers.
As organizations increasingly turn to cloud technologies to transform their businesses and workforces, implementing an effective zero-trust access control system becomes even more vital. While cloud technologies offer numerous advantages, they also greatly expand an organization's attack surface by creating numerous new entryways through which adversaries may gain entry and launch attacks against it.
Cloud systems can present many of the same vulnerabilities found in traditional IT systems - misconfigured S3 buckets can leave ports exposed to external attackers; insecure accounts expose data and APIs, while applications with unencrypted APIs could expose sensitive information. To combat these risks effectively, an effective security architecture must be in place, including cloud security posture management (CSPM),a workload protection platform (CWPP),and an access security broker (CASB).
Installing a Zero Trust Access Control solution enables employees to gain secure, private access to corporate applications and resources from any device, protecting applications, services, and data integrity in real-time. Citrix Secure Private Access continuously assesses access to IT-sanctioned apps based on role, location, and device to ensure only valid, safe content is delivered and that no threats are exploiting the app or its APIs.
As more workers leverage collaborative cloud services to work from home or other non-office locations and collaborate on projects with remote partners, contractors, and freelancers, this capability becomes ever more essential. Without an effective Zero Trust Access Control system, all these factors could create a substantial threat surface that adversaries could use to steal information or launch attacks on the infrastructure.
Cloud Monitoring
Maintaining robust measures for cloud application security helps organizations prevent data breaches that could disrupt business operations and cause substantial disruptions.
Implementing such measures helps ensure sensitive information only becomes available to authorized users and cannot be compromised by untrusted parties. Furthermore, such safeguards reduce the misconfiguration risk often arising in IT infrastructures due to human error and limited visibility.
An effective monitoring solution should provide businesses with a wide view of cloud-based processes, systems, and applications to increase observability and swiftly identify issues faster. In addition, built-in capabilities should protect against threats, including detecting changes in application behavior and monitoring and reporting suspicious activities.
Dynatrace provides intelligent monitoring tools designed specifically for system administrators. These include an installable agent which collects metrics across your entire system - this includes infrastructure tier, containers, and services - which Dynatrace then consolidates into an easily digestible dashboard to show trends in data gathered. This gives them insight into the performance of cloud apps.
Companies should adopt inclusive security policies and an organizational culture that prioritizes security for an enhanced security posture and to prevent data breaches that could jeopardize brand reputation.
Organizations must maintain visibility into these environments as they transition their IT infrastructures to the cloud. Every new application or workload increases the attack surface; black-hat hackers continue to develop their abilities, making the cloud an attractive target. Attackers may utilize account hijacking attacks against organizations to gain entry, and account hijacking attacks are among the most frequent cyberattacks.
Although not as severe as a data breach, this attack can still cause customer trust, revenue losses, and lasting reputational harm to companies. To address these risks effectively, businesses must create and implement a holistic cloud management strategy comprising multiple solutions.
