A “ports first” data security solution is a traditional approach that relies on port numbers to identify and filter network traffic. This approach has several limitations and security weaknesses, such as12:

Port numbers are not reliable indicators of the type or content of network traffic, as they can be easily spoofed or changed by malicious actors.

Port numbers do not provide any visibility into the application layer, where most of the attacks occur.

Port numbers do not account for the dynamic and complex nature of modern applications, which often use multiple ports or protocols to communicate.

Port numbers do not support granular and flexible policies based on user identity, device context, or application behavior. One of the security weaknesses that is caused by implementing a “ports first” data security solution in a traditional data center is that you may have to open up multiple ports and these ports could also be used to gain unauthorized entry into your datacenter. For example, if you have a web server that runs on port 80, you may have to open up port 80 on your firewall to allow incoming traffic. However, this also means that any other service or application that uses port 80 can also access your datacenter, potentially exposing it to attacks. Moreover, opening up multiple ports increases the attack surface area of your network, as it creates more entry points for attackers to exploit34. References: Common Open Port Vulnerabilities List - Netwrix, Optimize security with Azure Firewall solution for Azure Sentinel | Microsoft Security Blog, Which item accurately describes a security weakness that is caused by …, Which item accurately describes a security weakness … - Exam4Training

Cortex XDR is an endpoint tool or agent that can enact behavior-based protection. Behavior-based protection is a method of detecting and blocking malicious activities based on the actions or potential actions of an object, such as a file, a process, or a network connection. Behavior-based protection can identify and stop threats that are unknown or evade traditional signature-based detection, by analyzing the object’s behavior for suspicious or abnormal patterns. Cortex XDR is a comprehensive solution that provides behavior-based protection for endpoints, networks, and cloud environments. Cortex XDR uses artificial intelligence and machine learning to continuously monitor and analyze data from multiple sources, such as logs, events, alerts, and telemetry. Cortex XDR can detect and prevent advanced attacks, such as ransomware, fileless malware, zero-day exploits, and lateral movement, by applying behavioral blocking and containment rules. Cortex XDR can also perform root cause analysis, threat hunting, and incident response, to help organizations reduce the impact and duration of security incidents. References:

SSL/TLS encrypts and authenticates web-based communication to ensure secure data transmission over networks. It ensures privacy by encrypting the data exchanged between a client and a server, protecting it from interception or tampering. It doesn’t handle user input like passwords directly.

Xpanse is a tool from Palo Alto Networks that provides attack surface management by analyzing exposed services and internet-facing assets, giving security operations teams visibility into environmental risks and helping prioritize remediation of vulnerabilities.

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

Cyberterrorists are attackers who use the internet to recruit members to an ideology, to train them, and to spread fear and induce panic. Cyberterrorists may target critical infrastructure, government systems, or public services to cause disruption, damage, or harm. Cyberterrorists may also use the internet to disseminate propaganda, incite violence, or coordinate attacks. Cyberterrorists differ from other attacker profiles in their motivation, which is usually political, religious, or ideological, rather than financial or personal. References: Cyberterrorism, Cyber Threats, Cybersecurity Threat Landscape

Originally designed as a tool to assist organizations with compliance and industry-specific regulations, security information and event management (SIEM) is a technology that has been around for almost two decades

PCI DSS stands for Payment Card Industry Data Security Standard, which is a set of requirements intended to ensure that all companies that process, store, or transmit credit card information maintain a secure environment1. The standard is administered by the Payment Card Industry Security Standards Council, and its use is mandated by the major card brands2. PCI DSS covers 12 requirements for compliance, organized into six control objectives, such as building and maintaining a secure network and systems, protecting cardholder data, and implementing strong access control measures3.

Prisma Access provides firewall as a service (FWaaS) that protects branch offices from threats while also providing the security services expected from a next-generation firewall. The full spectrum of FWaaS includes threat prevention, URL filtering, sandboxing, and more.

The Privilege Escalation tactic in the MITRE ATT&CK framework involves techniques used by attackers to gain higher-level permissions on a system or network, allowing greater access to internal servers and sensitive data.

 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

A static routing protocol requires that routes be created and updated manually on a router or other network device. If a static route is down, traffic can’t be automatically rerouted unless an alternate route has been configured. Also, if the route is congested, traffic can’t be automatically rerouted over the less congested alternate route. Static routing is practical only in very small networks or for very limited, special-case routing scenarios (for example, a destination that’s used as a backup route or is reachable only via a single router). However, static routing has low bandwidth requirements (routing information isn’t broadcast across the network) and some built-in security (users can route only to destinations that are specified in statically defined routes).

SOAR tools ingest aggregated alerts from detection sources (such as SIEMs, network security tools, and mailboxes) before executing automatable, process-driven playbooks to enrich and respond to these alerts.

A Type 1 hypervisor, also known as a bare-metal hypervisor, is a software layer that runs directly on the hardware of a physical host computer, without requiring an underlying operating system. A Type 1 hypervisor can create and manage multiple isolated virtual machines (VMs), each with its own virtual (or guest) operating system and applications. A Type 1 hypervisor is hardened against cyber attacks, as it has a smaller attack surface and fewer vulnerabilities than a Type 2 hypervisor, which runs within an operating system. A Type 1 hypervisor also offers better performance, scalability, and resource utilization than a Type 2 hypervisor. References: 10 Palo Alto Networks PCCET Exam Practice Questions, Palo Alto Networks Certified Cybersecurity Entry-level Technician v1.0, FREE Cybersecurity Education Courses.

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.

Event Viewer is a native Windows application that can be used to inspect actions taken at a specific time. Event Viewer displays detailed information about significant events on your computer, such as application, security, system, and setup events. You can use Event Viewer to monitor and troubleshoot problems with your computer, such as hardware failures, software errors, security breaches, network issues, etc. Event Viewer allows you to filter, sort, and search events by various criteria, such as date and time, event level, event source, event ID, etc. You can also view the event properties, which provide more details about the event, such as the event description, user name, computer name, event data, etc. Event Viewer can help you identify the root cause of a problem, or provide evidence of a malicious activity, by inspecting the actions taken at a specific time on your computer. References:

Application allow listing is a security practice that permits only pre-approved (trusted) applications, files, and processes to run on a system. This approach helps prevent unauthorized or malicious software from executing, thereby reducing the attack surface.

CaaS, or Containers-as-a-Service, is a cloud service that allows users to manage and deploy applications using containers and clusters. CaaS can be situated between IaaS and PaaS in the spread of cloud computing services, based on how much is managed by the vendor. IaaS, or Infrastructure-as-a-Service, provides the lowest level of abstraction, where users have to manage the servers, storage, network, and operating system. PaaS, or Platform-as-a-Service, provides a higher level of abstraction, where users only have to manage the application code and data. FaaS, or Function-as-a-Service, provides the highest level of abstraction, where users only have to manage the functions or logic of the application. CaaS falls in between IaaS and PaaS, as it provides users with more control over the container orchestration and configuration than PaaS, but also simplifies the infrastructure management and scaling than IaaS123. References:

 A local area network (LAN) is a network that connects end-user devices such as personal computers, printers, scanners, and phones within a small geographic area, such as an office, school, or home. LANs allow users to share resources, such as files, applications, and internet access, among the connected devices. LANs typically use Ethernet or Wi-Fi as the communication medium and operate at high speeds with low error rates. LANs are usually owned and managed by a single person or organization. References: LANs, WANs, and Other Area Networks Explained, What is a LAN?

 A switch is a network device that connects multiple devices on a local area network (LAN) and forwards data packets between them. A switch can be identified by its icon, which is a rectangle with four curved lines on each side. In the attached network diagram, device D is the switch, as it matches the icon and connects three computers to device A, which is another network device. References:

An encoded string is a common technique used by attackers to obfuscate their malicious code or data. By decoding the string, a security operations engineer can reveal the true nature and intent of the attacker, and potentially discover indicators of compromise (IOCs) such as IP addresses, domain names, file names, etc. Decoding the string can also help the engineer to determine the type and severity of the incident, and the appropriate response actions. Therefore, decoding the string and continuing the investigation is the best option among the given choices. Saving the string to a new file and running it in a sandbox may be risky, as it could execute the malicious code and cause further damage. Running the string against VirusTotal may not yield any useful results, as the string may not be recognized by any antivirus engines. Appending the string to the investigation notes but not altering it may not provide any additional insight into the incident, and may delay the response process. References:

"Or split tunneling can be configured to allow internet traffic from the device to go directly to the internet, while other specific types of traffic route through the IPsec tunnel, for acceptable protection with much less performance degradation."

App-ID™ technology leverages the power of the broad global community to provide continuous identification, categorization, and granular risk-based control of known and previously unknown SaaS applications, ensuring new applications are discovered automatically as they become popular.

Stateful packet inspection firewalls Second-generation stateful packet inspection (also known as dynamic packet filtering) firewalls have the following characteristics:

? They operate up to Layer 4 (Transport layer) of the OSI model and maintain state information about the communication sessions that have been established between hosts on the trusted and untrusted networks.

? They inspect individual packet headers to determine source and destination IP address, protocol (TCP, UDP, and ICMP), and port number (during session establishment only) to

determine whether the session should be allowed, blocked, or dropped based on configured

firewall rules.

? After a permitted connection is established between two hosts, the firewall creates and

deletes firewall rules for individual connections as needed, thus effectively creating a tunnel that allows traffic to flow between the two hosts without further inspection of individual packets during the session.

? This type of firewall is very fast, but it is port-based and it is highly dependent on the

trustworthiness of the two hosts because individual packets aren’t inspected after the

connection is established.

Simplicity: Because each device is centrally managed, with routing based on application policies, WAN managers can create and update security rules in real time as network requirements change. Also, when SD-WAN is combined with zero-touch provisioning, a feature that helps automate the deployment and configuration processes, organizations can further reduce the complexity, resources, and operating expenses required to spin up new sites. ? Improved performance: By allowing efficient access to cloud-based resources without the need to backhaul traffic to centralized locations, organizations can provide a better user experience.

 A routed protocol is a protocol by which data can be routed. It provides appropriate addressing information in its internet layer or network layer to allow a packet to be forwarded from one network to another network. Examples of routed protocols are the Internet Protocol (IP) and Internetwork Packet Exchange (IPX). IP is the most widely used routed protocol on the Internet and other networks. It assigns a unique logical address to each device and enables data to be fragmented, reassembled, and routed across multiple networks. References:

A Host-Based Intrusion Prevention System (HIPS) is installed directly on an endpoint device (such as a server or workstation) and monitors local system activity, including processes, file access, and system calls, to detect and prevent malicious behavior.

TCP stands for Transmission Control Protocol, and it is one of the main protocols used in the internet. TCP provides reliable, ordered, and error-free delivery of data between applications 1. In terms of the OSI model, TCP is a transport-layer protocol. The transport layer is the fourth layer of the OSI model, and it is responsible for establishing end-to-end connections, segmenting data into packets, and ensuring reliable and efficient data transfer 2. The transport layer also provides flow control, congestion control, and error detection and correction mechanisms 2. TCP is not the only transport-layer protocol; another common one is UDP (User Datagram Protocol), which is faster but less reliable than TCP 3. References: 1: TCP/IP TCP, UDP, and IP protocols - IBM 2: Transport Layer | Layer 4 | The OSI-Model 3: TCP/IP Model vs. OSI Model | Similarities and Differences - Fortinet

An evil twin is a type of Wi-Fi attack that involves setting up a fake malicious Wi-Fi hotspot with the same name as a legitimate network to trick users into connecting to it. The attacker can then intercept the user’s data, such as passwords, credit card numbers, or personal information. The victim initiates the connection by choosing the fake network from the list of available Wi-Fi networks, thinking it is the real one. The attacker can also use a deauthentication attack to disconnect the user from the legitimate network and force them to reconnect to the fake one. References:

Workload security in a Cloud Native Security Platform (CNSP) is designed to secure containers, VMs, and serverless functions throughout the entire application lifecycle — from development to runtime — by detecting and blocking vulnerabilities, misconfigurations, and runtime threats.

Authentication is the component of the AAA (Authentication, Authorization, and Accounting) framework that verifies user identities (e.g., via passwords, certificates, or biometrics) before granting access to network resources.

Decryption is required to inspect TLS-encrypted traffic, allowing security tools (such as firewalls or intrusion prevention systems) to analyze the contents of the traffic for threats that would otherwise remain hidden within encrypted sessions.

Selective network security virtualization: Intra-host communications and live migrations are architected at this phase. All intra-host communication paths are strictly controlled to ensure that traffic between VMs at different trust levels is intermediated either by an on-box, virtual security appliance or by an off-box, physical security appliance.

 Border Gateway Protocol (BGP) is a protocol that enables ISPs and NSPs to exchange routing information among themselves. BGP is used to determine the best path for sending data packets across the Internet. BGP is also known as the protocol of the Internet backbone, as it connects different autonomous systems (ASes) that form the Internet. BGP is not used by end systems or local networks, but only by routers that operate at the border of ASes. BGP is a complex and dynamic protocol that can handle changes in network topology, traffic load, and policy requirements. BGP is also a scalable protocol that can support the growth of the Internet1234 References:

Whaling is a targeted phishing attack aimed at high-profile individuals, such as executives. The attacker impersonates a trusted entity (e.g., IT department) to trick the executive into revealing sensitive credentials. This is a form of spear phishing specifically focused on “big fish” targets.

The six pillars include:

1. Business (goals and outcomes)

2. People (who will perform the work)

3. Interfaces (external functions to help achieve goals)

4. Visibility (information needed to accomplish goals)

5. Technology (capabilities needed to provide visibility and enable people)

6. Processes (tactical steps required to execute on goals)

Cortex XDR is a detection and response platform that natively integrates network, endpoint, and cloud data to stop sophisticated attacks.

The Anthem data breach of 2015 was caused by a phishing scheme that captured a database administrator’s password. According to the U.S. Department of Health and Human Services (HHS) Office for Civil Rights (OCR), hackers sent phishing emails to an Anthem subsidiary. At least one employee responded. Attackers were able to plant malware on the company’s system and gain remote access to confidential information1. The breach exposed the electronic protected health information of almost 79 million people, including names, Social Security numbers, medical identification numbers, addresses, dates of birth, email addresses, and employment information2. References:

Full-disk encryption is a method of protecting data on a laptop that has been stolen by encrypting the entire hard drive, making it unreadable without the correct password or key. This prevents unauthorized access to the proprietary data stored on the laptop, even if the thief removes the hard drive and connects it to another device. Full-disk encryption can be enabled using built-in features such as BitLocker on Windows or FileVault on macOS, or using third-party software such as Absolute Home & Office12. References: How to Protect your Data if a Laptop is Lost or Stolen, What to do when your laptop is stolen, Palo Alto Networks Certified Cybersecurity Entry-level Technician

Containers are portable and lightweight alternatives to virtual machines that allow developers to package, isolate, and deploy applications across different cloud environments. Containers simplify the building and deploying of cloud native applications by providing consistent and efficient development, testing, and production environments. Containers also offer benefits such as rapid provisioning, high scalability, resource optimization, and security isolation. References:

A container-based NGFW is specifically designed to integrate with Kubernetes environments, providing full application visibility and control within containerized workloads. It operates at the pod level, making it ideal for securing dynamic microservices architectures.

DevSecOps takes the concept behind DevOps that developers and IT teams should work together closely, instead of separately, throughout software delivery and extends it to include security and integrate automated checks into the full CI/CD pipeline. The integration of the CI/CD pipeline takes care of the problem of security seeming like an outside force and instead allows developers to maintain their usual speed without compromising data security

Advanced WildFire is a Cloud-Delivered Security Service (CDSS) that detects zero-day malware using inline cloud machine learning (ML) and sandboxing techniques. It analyzes unknown files in real-time to identify and block new threats before they can cause harm.

Social engineering attacks manipulate human trust to gain unauthorized access or information. Convincing an employee that an attacker is also an employee builds rapport, lowering defenses for information disclosure or credential sharing. Similarly, impersonating a company representative and requesting unrelated personal data exploits authority bias to deceive victims. These tactics exploit psychological vulnerabilities rather than technical flaws and are prevalent initial steps in multi-stage attacks. Palo Alto Networks highlights the importance of training, multi-factor authentication, and behavior-based threat detection to mitigate social engineering risks effectively.

According to the NIST definition, cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction1. One of the essential characteristics of cloud computing is on-demand self-service, which means that users can request and obtain computing resources as needed, without requiring human intervention from the service provider2. On-demand network services are an example of this characteristic, as they allow users to access network resources such as bandwidth, routing, firewall, or load balancing, on demand and in a scalable manner3. References:

SOAR (Security Orchestration, Automation, and Response) differs from SIEM by adding automated incident response and workflow orchestration to the detection and alerting capabilities found in SIEM. This enables faster and more efficient handling of security incidents.

Scripting of manual tasks – SOAR platforms automate repetitive, manual security tasks through playbooks and scripting, improving response time and efficiency.

Consistent incident handling – SOAR ensures that incidents are managed in a standardized and repeatable manner, reducing errors and improving compliance.

Isolated system and log retention are not core advantages of SOAR.

SOAR tools ingest aggregated alerts from detection sources (such as SIEMs, network security tools, and mailboxes) before executing automatable, process-driven playbooks to enrich and respond to these alerts.

A Cloud Access Security Broker (CASB) secures SaaS applications and network data by providing visibility, data security, threat protection, and compliance enforcement. It acts as a control point between users and cloud service providers to enforce security policies.

Heap spray attacks exploit memory management vulnerabilities by injecting malicious code into a program’s heap to manipulate execution flow. Endpoint Detection and Response (EDR) platforms monitor memory and process behavior on endpoints, enabling the detection of such memory-based exploits through anomaly and behavior analysis. Palo Alto Networks’ Cortex XDR equips SOC teams with the tools to detect, analyze, and respond to heap spray and other in-memory attacks on company laptops in real time. EDR’s endpoint-centric visibility is crucial since heap spray attacks operate below network layers and often bypass traditional perimeter defenses.

"Weaponization: Next, attackers determine which methods to use to compromise a target endpoint. They may choose to embed intruder code within seemingly innocuous files such as a PDF or Microsoft Word document or email message."

Malicious Portable Executable (PE) files hidden inside PDFs represent a stealthy delivery tactic where attackers embed executable payloads within seemingly benign documents. When a user opens the PDF, the embedded PE executes, potentially installing malware. This approach combines social engineering with file obfuscation to bypass traditional detection methods. Palo Alto Networks’ Advanced WildFire sandboxing inspects such files by detonating them in isolated environments to observe behavior and identify hidden threats. This detection technique is critical for uncovering evasive malware concealed within common file types before they reach end-users.

Phishing is a type of attack that involves sending fraudulent emails that appear to be from legitimate sources, such as banks, companies, or individuals, in order to trick recipients into clicking on malicious links, opening malicious attachments, or providing sensitive information12. The link to a malware website in the email is an example of a malicious link, which may lead to the installation of malware, ransomware, spyware, or other malicious software on the user’s device, or the redirection to a fake website that mimics a legitimate one, where the user may be asked to enter their credentials, personal information, or financial details34. Phishing emails often use social engineering techniques, such as creating a sense of urgency, curiosity, or fear, to persuade the user to click on the link or attachment, or to reply to the email5. Phishing emails may also spoof the sender’s address, domain, or logo, to make them look more authentic and trustworthy6.

Whaling, pharming, and spam are not the correct answers for this question. Whaling is a specific type of phishing that targets high-profile individuals, such as executives, celebrities, or politicians, with the aim of stealing their confidential information or influencing their decisions7. Pharming is a type of attack that involves redirecting the user’s web browser to a fake website, even if they enter the correct URL, by modifying the DNS server or the user’s hosts file. Spam is the unsolicited or unwanted electronic messages, such as emails, texts, or instant messages, that are sent in bulk to a large number of recipients, usually for advertising, marketing, or scamming purposes. References:
