IDSs and IPSs also can be classified as knowledge-based (or signature-based) or behavior-based (or statistical anomaly-based) systems:

● A knowledge-based system uses a database of known vulnerabilities and attack profiles

to identify intrusion attempts. These types of systems have lower false-alarm rates than

behavior-based systems but must be continually updated with new attack signatures to

be effective.

● A behavior-based system uses a baseline of normal network activity to identify unusual

patterns or levels of network activity that may be indicative of an intrusion attempt.

These types of systems are more adaptive than knowledge-based systems and therefore

may be more effective in detecting previously unknown vulnerabilities and attacks, but they have a much higher false-positive rate than knowledge-based systems

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.

Least privileges access control is the capability of a Zero Trust network security architecture that leverages the combination of application, user, and content identification to prevent unauthorized access. Least privileges access control means that users and devices are only granted the permissions they need to perform their tasks, and nothing more. This helps reduce the attack surface and makes it more difficult for attackers to gain access to sensitive data or resources. Least privileges access control is based on the principle of Zero Trust, which assumes that there are attackers both within and outside of the network, so no users or devices should be automatically trusted. Zero Trust verifies user identity and privileges as well as device identity and security, and requires end-to-end encryption. Least privileges access control also involves careful management of user permissions and network segmentation, which limit the amount of information and length of time people can access something, and contain the damage if someone does get unauthorized access. References: What Is Zero Trust Architecture? | Microsoft Security, Zero Trust security | What is a Zero Trust network? | Cloudflare, What is Zero Trust Architecture? | SANS Institute, What Is a Zero Trust Architecture? | Zscaler, What is Zero Trust Architecture (ZTA)? - CrowdStrike.

Attack Surface Management (ASM) platforms focus on continuous discovery and monitoring of all internet-facing assets, both internal and external, to identify attack vectors, vulnerabilities, and exposures that could be exploited by threat actors.

Layer 4 of the TCP/IP model is the transport layer, which is responsible for providing reliable and efficient data transmission between hosts. The transport layer can use different protocols, such as TCP or UDP, depending on the requirements of the application. The transport layer also performs functions such as segmentation, acknowledgement, flow control, and error recovery. 1

The transport layer of the TCP/IP model corresponds to three layers of the OSI model: the transport layer, the session layer, and the presentation layer. The session layer of the OSI model manages the establishment, maintenance, and termination of sessions between applications. The session layer also provides services such as synchronization, dialogue control, and security. The presentation layer of the OSI model handles the representation, encoding, and formatting of data for the application layer. The presentation layer also performs functions such as compression, encryption, and translation. 23

A CI/CD platform is a comprehensive set of tools that help developers, engineers, and DevOps practitioners package and deliver software to the end users. A CI/CD platform automates the process of software testing and deployment, and enables faster and more reliable software releases. Jenkins is a popular open source CI/CD platform that supports a wide range of plugins and integrations to build, test, and deploy various types of applications. Jenkins can be configured to run on different platforms, such as Linux, Windows, or Docker, and can work with various version control systems, such as Git, SVN, or Mercurial. Jenkins can also orchestrate complex workflows, such as parallel or sequential execution, conditional branching, or parameterized triggering, using a graphical interface or a declarative syntax. Jenkins can help developers and DevOps teams achieve continuous integration and continuous delivery/deployment, by providing features such as:

•Pipeline as code: Jenkins allows users to define and manage their pipelines as code, using a domain-specific language (DSL) called Jenkinsfile. This enables users to store, version, and reuse their pipeline configurations, and to apply best practices such as code review and testing.

•Distributed builds: Jenkins can scale up or down to meet the demand of concurrent builds, by distributing the workload across multiple agents or nodes. This improves the performance and efficiency of the CI/CD process, and allows users to leverage different environments and resources for different stages of the pipeline.

•Plugin ecosystem: Jenkins has a rich and active community that contributes to its plugin ecosystem, which extends its functionality and compatibility with various tools and technologies. Users can find and install plugins from the Jenkins Plugin Manager, or create their own custom plugins using Java or Groovy.

•Blue Ocean: Jenkins offers a modern and user-friendly web interface called Blue Ocean, which simplifies the creation and visualization of pipelines. Blue Ocean provides features such as real-time feedback, interactive editing, branch and pull request support, and integration with popular chat platforms, such as Slack or Microsoft Teams.

In anti-malware, a false positive incorrectly identifies a legitimate file or application as malware. A false negative incorrectly identifies malware as a legitimate file or application. In intrusion detection, a false positive incorrectly identifies legitimate traffic as a threat, and a false negative incorrectly identifies a threat as legitimate traffic.

MITRE is a not-for-profit organization that operates research and development centers sponsored by the federal government. MITRE maintains the Common Vulnerabilities and Exposures (CVE) catalog, which is a dictionary of common names for publicly known cybersecurity vulnerabilities. CVE’s common identifiers, called CVE Identifiers, make it easier to share data across separate network security databases and tools, and provide a baseline for evaluating the coverage of an organization’s security tools12. References:

According to the NIST definition of cloud computing, Infrastructure as a Service (IaaS) is a cloud service model that provides “the capability to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications” 1. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls) 1. In other words, IaaS gives the user access to cloud-hosted physical and virtual servers, storage, and networking, as stated in the question. References: 1: SP 800-145, The NIST Definition of Cloud Computing | CSRC 2

Authorization is the component of the AAA (Authentication, Authorization, and Accounting) framework that regulates user access and permissions to resources after identity has been verified. It determines what actions or resources a user is allowed to access.
