How Can You Ensure Network Security If You Don’t Control The Network?

In today’s complex landscape of multi-cloud operations, businesses face significant challenges with managing data exfiltration and countering malicious traffic spanning multiple cloud service providers. The lack of visibility, control, and robust network security in these environments makes them vulnerable to advanced threats. Cybercriminals globally are constantly devising new ways to bypass traditional security protocols, putting sensitive data at risk.

Furthermore, the organizational structure of enterprises can exacerbate these vulnerabilities. Many companies operate with separate cloud teams dedicated to different providers, leading to inefficiencies and increased response times to security threats (MTTR). This separation results in organizational redundancies and complicates the implementation of a unified strategy to effectively protect against and mitigate malicious activities across all cloud platforms. To navigate these challenges, a coordinated and comprehensive approach to multi-cloud security is essential for today’s enterprises.

What Exactly is “Data Exfiltration”?

We’ll delve into the realm of unauthorized data access, where sensitive information is redirected to unapproved third-party locations. This form of data breach can lead to substantial reputational and financial harm for any organization. Understanding the intricacies of how data exfiltration occurs is crucial for safeguarding your company’s valuable assets.

Data exfiltration can unfold in various ways: it might happen through phishing, where corporate data is intercepted by adversaries. Alternatively, malware could infiltrate and spread across your network, compromising additional devices. This malware might remain dormant, evading detection by security systems, only to subversively exfiltrate data or accumulate information over time. Moreover, there are instances where an insider might intentionally transmit sensitive data to a malicious host, or an employee might exploit the organization’s cloud resources for activities like cryptocurrency mining, channeling critical information to places like the Bitcoin blockchain.

But what exactly is a botnet, and why is it important for you to be vigilant about it? Essentially, a botnet is a collection of interconnected devices, often spread across the globe, that a hacker controls. This control is exerted via Command & Control (C&C) software based at a command center. This software enables the hacker to dispatch commands to compromised systems to execute actions like Distributed Denial-of-Service (DDoS) attacks against other entities, pilfer data, distribute spam, or gain unfettered access to the infected device and its network capabilities. Awareness and proactive measures against such threats are key to protecting your organizational infrastructure.

Improving Your Security Posture Through Distributed Threat Enforcement

The ubiquity of internet access in cloud environments presents a significant business risk. If the infrastructure is compromised, traditional IDS (Intrusion Detection Systems) and IPS (Intrusion Prevention Systems) might struggle to detect and mitigate issues such as data exfiltration, crypto-mining, and Tor activities. This is largely due to the inherent lack of visibility and insufficient alerting mechanisms within these systems. To enhance your organization’s security posture, consider integrating distributed threat inspection services. These services complement existing security solutions by adding a crucial layer of protection, helping to safeguard your assets more effectively.

Adopting a repeatable network architecture that includes a common data plane is a straightforward yet powerful strategy. This approach not only secures your network but also sets the stage for distributed threat enforcement to naturally follow. With such a setup, your network can offer enhanced threat visibility across all gateways. This visibility allows for quicker threat identification and enables automatic remediation measures, significantly improving response times and security efficacy.

Implementing this model simplifies enterprise processes, workflows, and security investments. It not only reduces risk but also accelerates the resolution of security incidents by providing actionable context. This streamlined approach to network security not only fortifies your defenses but also enhances operational efficiency, making it easier for your organization to manage and scale its security measures as needed.

 Managing Security in Multi-Cloud Architectures

Cybercriminals employ various stealth techniques, often going undetected for extended periods while conducting data exfiltration or managing botnet operations, with the repercussions becoming apparent only after significant damage has occurred. This challenge is exacerbated in multi-cloud environments where different teams manage different cloud services. This fragmentation often hampers timely detection and necessitates enhanced coordination among teams to fortify security measures effectively.

A proactive security measure to consider is the implementation of an Intrusion Detection System (IDS). This system continually monitors your network, searching for known threats as well as unusual or malicious traffic patterns. Upon identifying potential security issues, the IDS promptly triggers alerts. It functions by analyzing known attack signatures and deviations from normal network activities, providing a critical layer of defense against cyber threats.

Additionally, integrating third-party Software-as-a-Service (SaaS) security solutions can further bolster your defensive strategy. This approach requires redirecting network traffic towards the SaaS provider for thorough inspection and analysis, often outside your immediate network. These services typically operate through a default routing system or through agents installed directly on network workloads. It’s also crucial to be aware of shadow IT activities, which can introduce new environments or alter traffic routes, potentially compromising the security infrastructure.

Meet My Solution: ThreatIQ with ThreatGuard

ThreatIQ with ThreatGuard introduces a groundbreaking approach to cloud network security within the Prosimo platform, providing extensive threat visibility across multiple clouds. This multi-cloud native network security solution is adept at identifying and intercepting traffic headed to known malicious destinations, ensuring your network remains secure.

Picture this: integrated threat visibility and control are embedded right into the network data plane by default. This creates a robust, complementary security framework that supports multiple cloud environments seamlessly. The beauty of this system lies in its simplicity and its capability to provide comprehensive protection without complicating your existing security setup.ThreatIQ leverages real-time Netflow data sent to CoPilot for meticulous threat analysis. The system’s default setting enables continuous threat inspection, which occurs at every network transit point. CoPilot scrutinizes all traffic, matching it against a database of known malicious hosts, showcasing how an intelligent data plane can enhance security awareness. On the other hand, ThreatGuard serves as the remediation mechanism, acting on the insights provided by CoPilot. If blocking is activated, these insights are communicated to the Prosimo Controller, which then disseminates firewall policies across all Prosimo gateways in the data path to block the traffic instantly. Additionally, it can alert specific users or distribution lists about potential threats, keeping everyone informed and prepared.
