How Google Security Command Center works

Threat discovery

Google Security Command Center’s (SCC) threat discovery is a pivotal component aimed at safeguarding the cloud environment. Using complex algorithms, SCC continuously searches for potential security risks, providing real-time alerts and insights. SCC can detect misconfigured storage buckets that might inadvertently expose sensitive data to the public or trace unusual IAM role assignments that could escalate privileges beyond intended limits. It also identifies potential web application vulnerabilities or traces of data exfiltration. By keeping an eye out for such security risks, SCC plays a pivotal role in ensuring that organizations maintain a robust security posture within the Google Cloud ecosystem.

• Continuous scanning: SCC threat discovery operates around the clock, monitoring your cloud assets and applications for any suspicious activities or vulnerabilities.
• Intelligent analysis: Leveraging machine learning algorithms, it categorizes threats based on severity, helping you prioritize your response.
• Real-time alerts: SCC notifies your security team immediately upon detecting a threat, allowing for swift action.
• Integration with other tools: It can be customized to work in harmony with other security tools (including Paladin Cloud), enhancing its effectiveness.

Security Health Analytics

SCC’s Security Health Analytics (SHA) is a tool for maintaining the health and integrity of your cloud systems. Through comprehensive monitoring and analysis, it ensures that everything is functioning as it should in a variety of ways:

• Monitoring security postures: It continually evaluates security configurations and user behaviors across various cloud services.
• Detecting misconfigurations: Identifying misaligned security settings helps prevent potential vulnerabilities. One vulnerability that SCC can identify is publicly accessible storage buckets. Cloud storage buckets, such as those in Google Cloud Storage, are used by organizations to store a plethora of data, ranging from website assets to sensitive organizational data. By default, these storage buckets are private. However, misconfigurations can sometimes leave them accessible to anyone with the link; they can even become publicly searchable, potentially leading to massive data breaches. 
  
  In the past, numerous instances have been reported where companies inadvertently left their storage buckets open to the public, leading to the exposure of sensitive data like customer details, internal documents, or even database backups. Cloud storage misconfigurations can be even more difficult to detect in multi-cloud environments. Third-party tools, like Paladin Cloud, provide the ability to detect security misconfigurations from multi-cloud environments like GCP, AWS, and Microsoft Azure. We will consider other limitations of SCC later in the article.
• Providing insightful reports: Through detailed analytics, SCC offers actionable insights into your security landscape. For instance, its ability to autogenerate comprehensive IAM role assignment reports can pinpoint anomalies, such as a marketing team member unexpectedly receiving database admin privileges. Such insights, whether indicating a mere oversight or a potential security breach, highlight SCC’s proficiency in proactively detecting risks and enabling organizations to promptly rectify problems and fortify their security measures.
• Facilitating compliance: SHA helps in ensuring that your cloud environment aligns with regulatory requirements, simplifying compliance management.

Data loss prevention

DLP in SCC is geared to protect the most vital asset in the digital age: data. These tools ensure that valuable data stays secure, preventing unauthorized access or accidental loss. DLP acts as a safeguard, ensuring that sensitive information remains within the secure confines of your organization:

• Robust encryption: It employs strong encryption methods to secure data both at rest and in transit.
• Access controls: By managing who can access what, it adds an extra layer of security.
• Monitoring data movement: DLP keeps a vigilant eye on data, alerting on unauthorized or suspicious access or transfers.
• Compliance alignment: It helps maintain compliance with various data protection regulations, supporting organizational adherence to legal requirements.
• Data classification and data masking/tokenization: It identifies sensitive elements within the data, such as credit card numbers or personally identifiable information (PII), and replaces them with tokens or masks.

Limitations of Google Security Command Center

While SCC is a powerful tool, it has its limitations. Understanding them will help you utilize SCC to its fullest potential.

Limitations in threat discovery 

Google SCC has made remarkable strides in threat discovery, enabling organizations to spot and respond to a myriad of vulnerabilities and threats within their Google Cloud environments. However, like any tool, there are complexities and evolving threat landscapes that might pose challenges even to SCC’s comprehensive detection algorithms.

One type of threat that sophisticated attackers employ is a “low and slow” attack strategy. Here, an adversary conducts malicious activities at a pace that’s deliberately designed to avoid detection. These types of attacks often involve:

• Slow scans: Instead of scanning a network for vulnerabilities rapidly, which could trigger alarms, attackers spread out their reconnaissance over days or even weeks.
• Gradual data exfiltration: Instead of quickly extracting large volumes of data, which might get flagged, attackers might siphon off smaller chunks of data over an extended period.
• Intermittent C&C communications: Command and control (C&C) servers, used to control compromised devices, might be contacted infrequently to avoid detection patterns.

SCC, which is designed to recognize malicious behavior patterns, might face challenges detecting such stealthy techniques. While it can spot rapid, abnormal spikes in traffic or unauthorized activities, the subtle and prolonged nature of “low and slow” attacks might sometimes fall below its detection threshold. This underscores the necessity for organizations to have layered security approaches, including behavioral analytics and advanced threat intelligence, to catch such sophisticated strategies.

Limitations in data loss prevention

SCC’s DLP is pivotal in identifying and protecting sensitive data across various GCP services. Designed to detect patterns and flag content that might be of concern, it has been instrumental in preventing many inadvertent data exposures. Nevertheless, like any advanced tool, there are certain intricate scenarios where its scope might not cover every risk.

This example demonstrates the potential shortcomings of DLP when dealing with encrypted or obfuscated sensitive data.

1. Setup: Create a sample text file with sensitive information, such as a Social Security Number (SSN). Encrypt or obfuscate this SSN using a custom algorithm or a standard method that isn’t typically recognized by conventional tools.
2. Configure DLP in SCC: Set up the DLP tool in SCC to monitor a Google Cloud Storage bucket where you’ll upload the file. Configure the DLP to scan for SSNs within stored files.
3. Upload the file: Place the text file with the encrypted or obfuscated SSN into the Cloud Storage bucket.
4. Run the scan: Activate the DLP scan and let it process the files within the bucket.
5. Observe: Post-scan, you may find that the DLP tool identifies direct text patterns that match the format of SSNs, but it might miss the encrypted or obfuscated SSN in the file.

Additional limitations to consider

The following are some additional limitations that are high-level considerations to take into account:

• Complexity in configuration: SCC’s native tools can sometimes become overwhelming and complex to configure, particularly for small and medium-sized businesses without dedicated security teams.
• Usage and quota limitations: SCC has some caps on usage that you should be aware of; they are described here. 
• Gaps in threat intelligence: SCC’s threat intelligence is substantial but can still miss certain specialized or evolving threats.
• Limited to Google Cloud: SCC only works with GCP. A third-party tool like Paladin Cloud offers oversight of multi-cloud environments.
