 A cloud native security platform (CNSP) is a set of security practices and technologies designed specifically for applications built and deployed in cloud environments. It involves a shift in mindset from traditional security approaches, which often rely on network-based protections, to a more application-focused approach that emphasizes identity and access management, container security and workload security, and continuous monitoring and response. A CNSP offers three main benefits for cloud native applications:

Agility: A CNSP enables faster and more frequent delivery of software updates, as security is built into the application and infrastructure from the ground up, rather than added on as an afterthought. This allows for seamless integration of security controls into the continuous integration/continuous delivery (CI/CD) pipeline, reducing the risk of security gaps or delays. A CNSP also leverages automation and orchestration to simplify and streamline security operations, such as configuration, patching, scanning, and remediation.

Digital transformation: A CNSP supports the adoption of cloud native technologies, such as microservices, containers, serverless, and platform as a service (PaaS), which enable greater scalability, deployability, manageability, and performance of cloud applications. These technologies also allow for more innovation and experimentation, as developers can easily create, test, and deploy new features and functionalities. A CNSP helps to protect these cloud native architectures from threats and vulnerabilities, while also ensuring compliance with regulations and standards.

Flexibility: A CNSP provides consistent and comprehensive security across different cloud environments, such as public, private, and multi-cloud. It also allows for customization and adaptation of security policies and controls to suit the specific needs and preferences of each application and organization. A CNSP can also integrate with other security tools and platforms, such as firewalls, endpoint protection, threat intelligence, and security information and event management (SIEM), to provide a holistic and unified view of the security posture and risk level of cloud applications.

Top Five Benefits of Cloud Native Application Security

Data security is the only type of security that the customer is fully responsible for when using a SaaS application. Data security refers to the protection of data from unauthorized access, use, modification, deletion, or disclosure. Data security includes aspects such as encryption, backup, recovery, access control, and compliance12. The customer is responsible for ensuring that their data is secure in transit and at rest, and that they comply with any applicable regulations or policies regarding their data.

The other types of security - physical, platform, and infrastructure - are the responsibility of the SaaS provider. Physical security refers to the protection of the hardware and facilities that host the SaaS application. Platform security refers to the protection of the software and services that run the SaaS application. Infrastructure security refers to the protection of the network and systems that support the SaaS application. The SaaS provider is responsible for ensuring that these layers of security are maintained and updated, and that they meet the required standards and certifications34. References:

A layer 2 switch will break up collision domains but not broadcast domains. To break up broadcast domains you need a Layer 3 switch with vlan capabilities.

To deliver secure east-west flows and secure Kubernetes workloads in a public cloud environment, you have two deployment options available: VM-Series and CN-Series.

VM-Series is a virtualized form factor of the Palo Alto Networks next-generation firewall that can be deployed in public cloud platforms such as AWS, Azure, Google Cloud, and Oracle Cloud. VM-Series provides comprehensive network security and threat prevention capabilities for protecting your cloud workloads and applications from cyberattacks. VM-Series can also integrate with native cloud services and third-party tools to enable automation, orchestration, and visibility across your cloud environment. VM-Series supports various deployment scenarios, such as securing internet-facing applications, protecting hybrid connectivity, segmenting internal networks, and enabling secure DevOps12.

CN-Series is a containerized form factor of the Palo Alto Networks next-generation firewall that can be deployed in Kubernetes environments. CN-Series provides granular network security and threat prevention capabilities for protecting your Kubernetes pods and namespaces from cyberattacks. CN-Series can also integrate with Kubernetes network plugins and services to enable dynamic policy enforcement, service discovery, and visibility across your Kubernetes clusters. CN-Series supports various deployment scenarios, such as securing ingress and egress traffic, enforcing microsegmentation, and enabling secure DevSecOps34.

Routing Information Protocol (RIP) is an example of a distance-vector routing protocol that uses hop count as its routing metric. To prevent routing loops, in which packets effectively get stuck bouncing between various router nodes, RIP implements a hop limit of 15, which limits the size of networks that RIP can support. After a data packet crosses 15 router nodes (hops) between a source and a destination, the destination is considered unreachable.

Dynamic analysis is a method of malware analysis that executes the malware in a controlled environment and observes its behavior and effects. Dynamic analysis can reveal the malware’s network activity, file system changes, registry modifications, and other indicators of compromise. Dynamic analysis is performed by Palo Alto Networks WildFire, a cloud-based service that analyzes unknown files and links from various sources, such as email attachments, web downloads, and firewall traffic. WildFire uses a custom-built, evasion-resistant virtual environment to detonate the submissions and generate detailed reports and verdicts. WildFire can also share the threat intelligence with other Palo Alto Networks products and partners to prevent future attacks. References: WildFire Overview, WildFire Features, WildFire Dynamic Analysis

 A sanctioned application is an application that is approved by the IT department and meets the security and compliance requirements of the organization. Sanctioned applications are allowed to access the organization’s network and data and are monitored and protected by the IT department. Examples of sanctioned applications are Office 365, Salesforce, and Zoom. Sanctioned applications are different from unsanctioned, prohibited, and tolerated applications, which are not approved by the IT department and may pose security risks to the organization. Unsanctioned applications are applications that are used by the employees without the IT department’s knowledge or consent, such as Dropbox, Gmail, or Facebook. Prohibited applications are applications that are explicitly forbidden by the IT department, such as BitTorrent, Tor, or malware. Tolerated applications are applications that are not approved by the IT department, but are not blocked or restricted, such as Skype, Spotify, or YouTube. References: Palo Alto Networks Certified Cybersecurity Entry-level Technician (PCCET), Cloud Security Fundamentals - Module 4: Cloud Security Best Practices, Application Visibility and Control
