Risks in Cloud environments, such as those provided by Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS), can be automatically detected and addressed with the help of Cloud Security Posture Management (CSPM). 

Applying best practices for cloud security consistently across hybrid, multi-cloud, and container environments, CSPM is used for risk visualisation and assessment, compliance monitoring, incident response, and DevOps integration.

Definition of Cloud Security Posture Management

Companies worldwide are adopting cloud computing and storage to cut costs and boost flexibility. The risk of systems or data being exposed grows as more applications and data are moved to the cloud. 

In addition, as businesses increasingly use multiple public clouds to host their services, the challenge of ensuring consistent levels of safety and regulation is exacerbated.

The Importance of CSPM in Today’s World

A cloud could connect and disconnect from thousands of networks daily. 

Due to their inherent instability, clouds are both potent and difficult to protect. The challenge of protecting cloud-based infrastructure is growing in importance as a cloud-first mentality gains traction.

Reasons why conventional security measures fail in the cloud include:

• Lack of centralisation makes visibility nearly impossible to achieve.
• There is no safe zone because manual processes cannot be performed at the required scale or speed.

Even though cloud computing saves money in the long run, the time and effort required to ensure its security—what with all the moving parts of microservices, containers, Kubernetes, serverless functions, etc.—can eat into the return on investment. 

As new technologies emerge faster than businesses can find security professionals with experience working with them, the infamous cybersecurity skills gap becomes increasingly essential.

Infrastructure as Code (IaC) is a concept that has emerged alongside these new technologies; in IaC, infrastructure is managed and provisioned based on machine-readable definition files. 

This API-driven strategy is fundamental to cloud-first environments because it facilitates rapid infrastructure adaptation, but it also makes it simple to code inadvertently in vulnerabilities. According to Gartner, misconfigurations account for 95% of security breaches and will cost businesses around $5.1 trillion in the coming year.

Lack of exposure is the underlying vulnerability that worsens all of these other problems. Enterprise clouds are dynamic, complex environments with hundreds of thousands of instances and accounts, making it impossible to track who is doing what manually. 

A misconfiguration’s resulting vulnerability might only be uncovered for days, weeks, or even once there is a breach if that assistance is provided.

Management of cloud security posture solves these problems by keeping a constant eye on the cloud’s vulnerability in preventing, detecting, responding to, and anticipating the subsequent manifestations of risk.

Exactly What Causes Misconfigurations to Set In?

Misconfigurations are common and usually happen unintentionally. Since you can use APIs to program public cloud infrastructure, any misconfigurations pose a significant threat to businesses. 

Please properly manage interdependent resources, such as Kubernetes, serverless functions, and containers, to avoid undesirable outcomes. This happens when administrators need a complete picture of how their resources interact. 

Hence, they end up applying for permissions from one resource to another without knowing which permissions are necessary.

Lastly, the size and complexity of modern business environments make it challenging to monitor and update tens of thousands of resources and accounts. Developers may misplace vital assets if they set too many permissions or fail to keep tabs on them.

Advantages of Managing Your Cloud’s Security Posture

Intentional and unintentional risks exist side by side. Intentional threats, such as those from the outside or dishonest employees, are the primary target of cloud security solutions. 

But unintentional errors can cause massive damage, such as exposing sensitive data to the public in S3 buckets.

An improperly configured S3 bucket exposed at least 10 million files in November 2020, including personal information belonging to travellers and travel agents. That’s the latest in a string of major leaks that have dogged some of the most eminent names in business and politics over the past few years.

With Cloud Security Posture Management, you won’t have to switch between consoles or normalise data from different providers to see what’s happening across your multi-cloud deployments, which helps you avoid those accidental vulnerabilities. Automatically preventing misconfigurations and speeding up time to value are both benefits.

The centralised nature of CSPMs means that employees are less likely to experience alert fatigue due to receiving notifications from fewer than the typical six or more systems. Artificial intelligence is used to reduce the number of false positives. This boosts efficiency within the security operations centre (SOC).

This is because CSPMs are constantly checking the environment and reporting on whether or not policies are being followed. When a change in trajectory is detected, you can take corrective actions mechanically.

Of course, CSPM’s continuous scans of the entire infrastructure reveal previously unknown threats, and quicker detection means less downtime for fixing them.

CSPM Improves Cloud Security by Making All Settings Transparent

By allowing companies to monitor their public cloud infrastructure, CSPM solutions are invaluable. 

Due to the rapid progress of cloud computing, many companies need more visibility into their cloud infrastructure, including the number of active instances and their current configurations. Since misconfigurations may go undetected for extended periods due to a lack of visibility, it may be more challenging to ensure the security of the applications.

Due to their sheer size and complexity, enterprises can no longer rely on manual security management tools in today’s cloud environments.

A Powerful CSPM Approach Fueled by Automation

Organisations can benefit from automating their CSPM security processes because they do so in a few key ways:

• Determine potential dangers

It is essential to cloud security that risks be identified and categorised.

• Control the aftermath of an incident

Analyse in a centralised fashion the processes in place for finding threats, isolating them, and fixing them.

• Categorise and take stock of possessions.

For cloud security, it is essential to have a clear view of what assets are hosted in the cloud and how they are set up.

• Maintain constant vigilance and evaluation of compliance procedures

There will be automated tools to find and fix internal security and regulatory compliance issues.

• Maintain a watchful eye on the status quo

Determine whether or not the recently acquired property meets all security requirements. In addition, they can spot dangers that weaken cloud security.

What Is the Process for Managing the Cloud’s Security Posture?

Discovery and visibility, continuous threat detection, misconfiguration management and remediation, and DevSecOps integration are some of the benefits of using Cloud Security Posture Management.

• Integration of Dev and SecOps

Through CSPM, the administrative burden of managing multiple cloud service providers and associated accounts is greatly diminished. Centralised visibility and control over all cloud resources are made possible by cloud-native, agentless posture management. 

Security teams can prevent compromised assets from advancing in the application lifecycle, and the DevOps and security operations teams can work from a single source of truth.

Integrating the CSPM with the SIEM will improve visibility and provide insights and context regarding configuration errors and policy violations.

Integrating with existing DevOps tool sets, the CSPM will allow quicker remediation and response within the DevOps tool set. Security operations, DevOps, and infrastructure teams can all benefit from a common understanding that reports and dashboards provide.

• Controlling Malfunctioning Configurations and Fixing Them

By continuously comparing cloud application configurations to industry and organisational benchmarks, CSPM eliminates security risks and accelerates delivery by identifying and remediating violations in real time. You can use guided remediation to fix misconfigurations, open IP ports, and unauthorised modifications that expose cloud resources, and guardrails are provided to help developers avoid making these mistakes. 

Data storage is tracked and managed to ensure that only authorised users have access to stored information and that sensitive information is never exposed by accident. All database instances are tracked to guarantee that high availability, backups, and encryption are set up and working correctly.

Put in place the proper protections against online threats, both for your own devices and for the various devices used by members of your household. Kaspersky Internet Security can protect your computer from ransomware and other malicious files without slowing it down.

• Appearance and Identification

Assets and security settings in cloud infrastructure can be found and viewed with the help of CSPM. Users have access to an accurate consolidated data store across all cloud deployments. 

Misconfigurations, metadata, networking, security, and change activity are all automatically uncovered upon deployment in the cloud. Accounts, regions, projects, and virtual networks can all have their respective security policies administered from the same place.

• Uninterrupted Monitoring for Threats

By utilising a streamlined threat identification and management method, CSPM can proactively detect threats throughout the entire application development lifecycle. 

Because the CSPM zeroes in on the weak spots your adversaries are most likely to exploit, prioritises vulnerabilities according to the state of your infrastructure and stops potentially dangerous code from entering production, you’ll see a significant decrease in the volume of alerts you receive. 

The CSPM will also use real-time threat detection to monitor any malicious or unauthorised activity or access to protected cloud resources.

Cloud Security Product Matrix Distinctions

• Cloud Access Security Brokers (CASBs)

CASBs are security enforcement nodes between cloud service providers and their end-users. Before letting data into the network, they check to see if it abides by the policies in place. 

Continuous compliance monitoring, configuration drift prevention, and security operations centre investigations are features typically offered by CSPMs, while CASBs focus on firewalls, authentication, malware detection, and DLP. 

CSPMs don’t just keep tabs on the network’s health; they also define the ideal configuration of the network and make it their mission to enforce that policy across the board.

• Cloud Infrastructure Security Posture Assessment (CISPA)

The original CSPMs were dubbed CISPA. Automating everything from the most basic task execution to the most complex use of artificial intelligence is all part of CSPMs, whereas CISPAs mainly focus on reporting.

• Cloud Workload Protection Platforms (CWPPs)

Cloud Workload Protection Platforms (CWPPs) offer comprehensive protection for cloud workloads from any provider, anywhere in the world. They are based on repurposed versions of older technologies like vulnerability management and anti-malware that have been updated to fit the requirements of today’s infrastructure. 

CSPMs are tailored specifically for the cloud and perform an in-depth analysis of the entire system, not just the workloads. Advanced automation, AI, and guided remediation are part of a CSPM, making it possible for users to identify issues and take corrective action.

Conclusion

Public cloud security and compliance management (CSPM) are essential because it allows businesses to proactively identify and automatically fix vulnerabilities, misconfigurations, misuse, and compliance violations in the cloud. Separate from or integrated into a larger cloud-native security platform, CSPM tools offer a variety of benefits.

When continuous monitoring, automation, and correct configuration are applied to cloud security issues, they become easier to resolve. However, CSPM methods offer benefits beyond those already mentioned.

CSPM can be used to determine the most popular technologies, map the workflows of security teams, ensure the integrity of a newly implemented system, and discover unused assets. This is another way CSPM can help businesses save money and spot crucial areas for employee development. Thus, CSPM becomes a formidable asset in any cloud infrastructure.
