Local systems can eliminate vulnerabilities by patching systems and software effectively and continuously. Patching is the process of applying updates or fixes to software or hardware components that have known vulnerabilities or bugs. Patching can prevent attackers from exploiting these vulnerabilities and compromising the security or functionality of the systems. Patching should be done regularly and promptly, as new vulnerabilities are constantly discovered and exploited by cybercriminals. Patching should also be done effectively, meaning that the patches are tested and verified before deployment, and that they do not introduce new vulnerabilities or issues. Patching should also be done continuously, meaning that the systems are monitored for new vulnerabilities and patches are applied as soon as they are available. Continuous patching can reduce the window of opportunity for attackers to exploit unpatched vulnerabilities and cause damage or data breaches. References:

Account discovery is a technique in the MITRE ATT & CK framework under the Discovery tactic. It involves adversaries attempting to identify user accounts on a system or network.

Credential access, lateral movement, and resource development are tactics — high-level objectives an attacker is trying to achieve.

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

Code security in cloud environments involves using tools like Static Application Security Testing (SAST) to automatically analyze source code for vulnerabilities before deployment. This helps identify and remediate potential threats early in the software development lifecycle.

Static routing is a form of routing that occurs when a router uses a manually-configured routing entry, rather than information from dynamic routing traffic 1. Static routing has some advantages, such as simplicity, low overhead, and full control, but it also has some disadvantages, such as:

•Manual reconfiguration: Static routes require manual effort to configure and maintain. This can be time-consuming and error-prone, especially in large networks with many routes. If there is a change in the network topology or a link failure, the static routes need to be updated manually by the network administrator 23.

•Single point of failure: Static routing is not fault tolerant. This means that if the path used by the static route stops working, the traffic will not be rerouted automatically. The network will be unreachable until the failure is repaired or the static route is changed manually. Dynamic routing, on the other hand, can adapt to network changes and find alternative paths 23.

Mobile Device Management (MDM) enables firewall administrators to remotely and efficiently deploy corporate configurations, such as email accounts and VPN settings, to targeted mobile devices. It ensures consistent policy enforcement and security across all managed devices.

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.

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.

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:

 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.

Code security focuses on identifying vulnerabilities and misconfigurations early in the development process. It uses tools like static code analysis and infrastructure-as-code (IaC) scanning to ensure secure coding and configuration before deployment.

SecOps is the organizational function that is responsible for security automation and eventual vetting of the solution to help ensure consistency through machine-driven responses to security issues. SecOps is a collaboration between security and operations teams that aims to align their goals, processes, and tools to improve security posture and efficiency. SecOps can leverage automation to simplify and accelerate security tasks, such as threat detection, incident response, vulnerability management, compliance enforcement, and more. Security automation can also reduce human errors, enhance scalability, and free up resources for more strategic initiatives. 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.

Signature-based malware detection relies on a constantly updated database of known threat signatures to identify malicious files or activity. Without frequent updates, it becomes ineffective against newly emerging threats.

The IP stack adds source (sender) and destination (receiver) IP addresses to the TCP segment (which now is called an IP packet) and notifies the server operating system that it has an outgoing message ready to be sent across the network.

Containers encapsulate applications and their dependencies into lightweight, portable units that can run consistently across multiple environments. This abstraction supports cloud-native development by enabling microservices architectures, rapid deployment, and scaling within orchestration platforms like Kubernetes. Containers accelerate cloud migration by decoupling applications from infrastructure, facilitating automation, and continuous integration/continuous deployment (CI/CD) workflows. Palo Alto Networks addresses container security by integrating runtime protection, vulnerability scanning, and compliance enforcement within its Prisma Cloud platform, ensuring safe adoption of cloud-native tools and methodologies.

 Connectors and interfaces are the components that enable a SIEM to collect, process, and analyze data from various sources, such as Microsoft 365 services and applications1, cloud platforms, network devices, and security solutions. Connectors are responsible for extracting and transforming data from the source systems, while interfaces are responsible for sending and receiving data to and from the SIEM server. Without connectors and interfaces, a SIEM cannot operate correctly and ensure a translated flow from the system of interest to the SIEM data lake. 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.

Automation in SOAR (Security Orchestration, Automation, and Response) is the process of programming tasks, alerts, and responses to security incidents so that they can be executed without human intervention. Automation in SOAR helps security teams to handle the huge amount of information generated by various security tools, analyze it through machine learning processes, and take appropriate actions based on predefined rules and workflows. Automation in SOAR also reduces the manual effort and time required for security operations, improves the accuracy and efficiency of threat detection and response, and provides consistency in handling security issues across different environments and scenarios.

In a host-based architecture, the server (host) handles all processing tasks, while the client mainly provides input/output. This centralizes control, processing, and data storage on the server, reducing the client’s role to that of a terminal.

Prisma Access is a cloud-delivered security platform that provides policy enforcement, secure access, and threat prevention for mobile users and remote networks, ensuring consistent security regardless of location.

Endpoint antivirus software is a type of software designed to help detect, prevent, and eliminate malware on devices, such as laptops, desktops, smartphones, and tablets. Endpoint antivirus software can block viruses that are not seen and blocked by the perimeter firewall, which is a network security device that monitors and controls incoming and outgoing network traffic based on predefined security rules. Perimeter firewall can block some known viruses, but it may not be able to detect and stop new or unknown viruses that use advanced techniques to evade detection. Endpoint antivirus software can provide an additional layer of protection by scanning the files and processes on the devices and using various methods, such as signatures, heuristics, behavior analysis, and cloud-based analysis, to identify and remove malicious code123. References:

SaaS financial botnets are often sold as kits, enabling attackers to license and reuse the malicious code easily.

These kits allow attackers to build and operate their own botnets, often targeting financial data or systems.

Financial botnets are typically smaller but more targeted than spamming or DDoS botnets. Botnets are not a defense mechanism, but rather a threat.

Detection of threats using data analysis – SIEM platforms analyze collected data to identify suspicious patterns and detect threats.

Ingestion of log data – SIEM systems collect and centralize log data from various sources, which is essential for analysis, correlation, and alerting.

Automation and prevention are more aligned with SOAR and firewall/EDR functionalities, not the core operations of SIEM.

● Type 1 (native or bare metal). Runs directly on the host computer’s hardware

● Type 2 (hosted). Runs within an operating system environment

A physical firewall is ideal for environments like a company headquarters that require redundant power, high throughput, and dedicated hardware for maximum reliability and performance. It supports more robust failover and scalability compared to virtual or containerized options.

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:

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

Command and Control: Attackers establish encrypted communication channels back to command-and-control (C2) servers across the internet so that they can modify their attack objectives and methods as additional targets of opportunity are identified within the victim network, or to evade any new security countermeasures that the organization may attempt to deploy if attack artifacts are discovered.

Signature-based antivirus software is a type of security software that uses signatures to identify malware. Signatures are bits of code that are unique to a specific piece of malware. When signature-based antivirus software detects a piece of malware, it compares the signature to its database of known signatures12. If a match is found, the software can do three things to provide protection:

Alert system administrators: The software can notify the system administrators or the users about the malware detection, and provide information such as the name, type, location, and severity of the malware. This can help the administrators or the users to take appropriate actions to prevent further damage or infection3.

Quarantine the infected file: The software can isolate the infected file from the rest of the system, and prevent it from accessing or modifying any other files or processes. This can help to contain the malware and limit its impact on the system4.

Delete the infected file: The software can remove the infected file from the system, and prevent it from running or spreading. This can help to eliminate the malware and restore the system to a clean state4.

A botnet is a network of computers or devices that are infected by malware and controlled by a malicious actor, known as the botmaster or bot-herder. The botmaster uses a command and control (C2) server or channel to send instructions to the bots and receive information from them. The C2 communication is essential for the botmaster to maintain control over the botnet and use it for various malicious purposes, such as launching distributed denial-of-service (DDoS) attacks, stealing data, sending spam, or mining cryptocurrency. Therefore, the key to “taking down” a botnet is to prevent the bots from communicating with the C2 server or channel. This can be done by disrupting, blocking, or hijacking the C2 communication, which can render the botnet ineffective, unstable, or inaccessible. For example, security researchers or law enforcement agencies can use techniques such as sinkholing, domain name system (DNS) poisoning, or domain seizure to redirect the bot traffic to a benign server or a dead end, cutting off the connection between the bots and the botmaster. Alternatively, they can use techniques such as reverse engineering, decryption, or impersonation to infiltrate the C2 server or channel and take over the botnet, either to disable it, monitor it, or use it for good purposes. References:

An AAAA record is a type of DNS record that maps a domain name or a subdomain to an IPv6 address. IPv6 is the latest version of the Internet Protocol (IP) that uses 128-bit addresses to identify devices on the internet. An AAAA record is similar to an A record, which maps a domain name or a subdomain to an IPv4 address, but with a different format and length. An example of an AAAA record is:

example-website.com. IN AAAA 2001:db8::1234

In the example above, the record is made up of the following elements:

example-website.com.: The domain name or the subdomain that is mapped to an IPv6 address.

IN: The class of the record, which indicates that it is on the internet.

AAAA: The type of the record, which indicates that it is an IPv6 address record.

2001:db8::1234: The IPv6 address that is mapped to the domain name or the subdomain. The address is written in hexadecimal notation, with colons separating each 16-bit segment. Double colons (::) can be used to compress consecutive zero segments.

IaaS (Infrastructure as a Service) is a cloud computing model that delivers on-demand infrastructure resources to organizations via the cloud, such as compute, storage, networking, and virtualization1. Customers do not have to manage, maintain, or update their own data center infrastructure, but are responsible for the operating system, middleware, virtual machines, and any apps or data1. Therefore, IaaS gives customers full control over the operating system(s) running on their cloud computing platform, as well as the flexibility to customize and configure their infrastructure according to their needs2. References: What are the different types of cloud computing? | Google Cloud, PaaS vs IaaS vs SaaS: What’s the difference? | Google Cloud

 A zero-day threat is an attack that takes advantage of a security vulnerability that does not have a fix in place. It is referred to as a “zero-day” threat because once the flaw is eventually discovered, the developer or organization has “zero days” to then come up with a solution. A zero-day threat can compromise a system or network by exploiting the unknown vulnerability, and can cause data loss, unauthorized access, or other damages. Zero-day threats are difficult to detect and prevent, and require advanced security solutions and practices to mitigate them. References:

Identity and access management (IAM) is a software service or framework that allows organizations to define user or group identities within software environments, then associate permissions with them. The identities and permissions are usually spelled out in a text file, which is referred to as an IAM policy.

● Reduce the attack surface: Best-of-breed technologies that are natively integrated provide a prevention architecture that inherently reduces the attack surface. This type of architecture allows organizations to exert positive control based on applications, users, and content, with support for open communication, orchestration, and visibility.

● Prevent all known threats, fast: A coordinated security platform accounts for the full scope of an attack across the various security controls that compose the security posture, thus enabling organizations to quickly identify and block known threats.

● Detect and prevent new, unknown threats with automation: Security that simply detects

threats and requires a manual response is too little, too late. Automated creation and

delivery of near-real-time protections against new threats to the various security solutions in the organization’s environments enable dynamic policy updates. These updates are

designed to allow enterprises to scale defenses with technology, rather than people.

Short-range wireless:

● Adaptive Network Technology+ (ANT+): ANT+ is a proprietary multicast wireless sensor

network technology primarily used in personal wearables, such as sports and fitness sensors.

● Bluetooth/Bluetooth Low-Energy (BLE): Bluetooth is a low-power, short-range

communications technology primarily designed for point-to-point communications between wireless devices in a hub-and-spoke topology. BLE (also known as Bluetooth Smart or Bluetooth 4.0+) devices consume significantly less power than Bluetooth devices and can access the internet directly through 6LoWPAN connectivity.

● Internet Protocol version 6 (IPv6) over Low-Power Wireless Personal Area Networks

(6LoWPAN): 6LoWPAN allows IPv6 traffic to be carried over low-power wireless mesh

networks. 6LoWPAN is designed for nodes and applications that require wireless internet

connectivity at relatively low data rates in small form factors, such as smart light bulbs

and smart meters.

● Wi-Fi/802.11: The Institute of Electrical and Electronics Engineers (IEEE) defines the 802

LAN protocol standards. 802.11 is the set of standards used for Wi-Fi networks typically

operating in the 2.4GHz and 5GHz frequency bands. The most common implementations

today include:

‒ 802.11n (labeled Wi-Fi 4 by the Wi-Fi Alliance), which operates on both 2.4GHz and 5GHz

bands at ranges from 54Mbps to 600Mbps

‒ 802.11ac (Wi-Fi 5), which operates on the 5GHz band at ranges from 433Mbps to 3.46

Gbps

‒ 802.11ax (Wi-Fi 6), which operates on the 2.4GHz and 5GHz bands (and all bands between 1 and 6GHz, when they become available for 802.11 use) at ranges up to 11Gbps

● Z-Wave: Z-Wave is a low-energy wireless mesh network protocol primarily used for home

automation applications such as smart appliances, lighting control, security systems,

smart thermostats, windows and locks, and garage doors.

● Zigbee/802.14: Zigbee is a low-cost, low-power wireless mesh network protocol based on the IEEE 802.15.4 standard. Zigbee is the dominant protocol in the low-power networking market, with a large installed base in industrial environments and smart home products.

Cybercriminals are attackers who act independently or as part of an unlawful organization, such as a crime syndicate or a hacker group. Their main motivation is to make money by exploiting vulnerabilities in systems, networks, or applications. They use various methods, such as ransomware, phishing, identity theft, fraud, or botnets, to steal data, extort victims, or disrupt services. Cybercriminals often target individuals, businesses, or institutions that have valuable or sensitive information, such as financial, personal, or health data. Cybercriminals are constantly evolving their techniques and tools to evade detection and countermeasures. They may also collaborate with other cybercriminals or hire hackers to perform specific tasks. References:

SOAR stands for security orchestration, automation and response. It is a software solution that enables security teams to integrate and coordinate separate tools into streamlined threat response workflows. SOAR systems allow for accelerated incident response through the execution of standardized and automated playbooks that work upon inputs from security technology and other data flows. SOAR systems can also help ensure consistency, reduce human errors, and improve efficiency and scalability of security operations. References:

" 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.

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.

From a business perspective, XDR platforms enable organizations to prevent successful cyberattacks as well as simplify and strengthen security processes.

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.

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:

Advanced Threat Prevention is the Palo Alto Networks solution that has replaced legacy Intrusion Prevention Systems (IPS). It offers inline, ML-powered threat detection and evasion-resistant inspection to block sophisticated threats in real time, going beyond traditional signature-based IPS.

A containerized architecture packages software along with its dependencies, libraries, and configuration into an isolated unit called a container. This ensures consistent behavior across environments and simplifies deployment and scaling.

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.

Application (Layer 4 or L4): This layer loosely corresponds to Layers 5 through 7 of the OSI model.

Transport (Layer 3 or L3): This layer corresponds to Layer 4 of the OSI model.

Internet (Layer 2 or L2): This layer corresponds to Layer 3 of the OSI model.

Network Access (Layer 1 or L1): This layer corresponds to Layers 1 and 2 of the OSI model

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:

The 12 Best Endpoint Security Software Solutions and Tools [2024]

Attack communication traffic is usually hidden with various techniques and

tools, including:

● Encryption with SSL, SSH (Secure Shell), or some other custom or proprietary encryption

● Circumvention via proxies, remote access tools, or tunneling. In some instances, use of

cellular networks enables complete circumvention of the target network for attack C2 traffic.

● Port evasion using network anonymizers or port hopping to traverse over any available open

ports

● Fast Flux (or Dynamic DNS) to proxy through multiple infected endpoints or multiple,

ever-changing C2 servers to reroute traffic and make determination of the true destination

or attack source difficult

● DNS tunneling is used for C2 communications and data infiltration

A worm is a type of malware that replicates itself to spread rapidly through a computer network. Unlike a virus, a worm does not need a host program or human interaction to infect other devices. A worm can consume network bandwidth, slow down the system performance, or deliver a malicious payload, such as ransomware or a backdoor123. References: Types of Malware & Malware Examples - Kaspersky, 10 types of malware + how to prevent malware from the start, Computer worm - Wikipedia

A worm replicates through the network while a virus replicates, not necessarily to spread through the network.

Phishing is a type of email attack where the attacker sends a lot of malicious emails in an untargeted way, pretending to be a trusted source, such as a bank or an online retailer, to trick users into revealing sensitive information, such as passwords or credit card numbers. Attackers use the information to steal money or to launch other attacks. A fake email from a bank asking you to click a link and verify your account details is an example of phishing1 References:

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.

A credit card number is an example of PII that you need to prevent from leaving your enterprise network. PII, or personally identifiable information, is any information that can be used to identify an individual, either alone or in combination with other data. PII can be sensitive or non-sensitive, depending on the level of protection required and the potential harm if exposed. Sensitive PII includes data that can directly identify an individual and cause significant harm if leaked or stolen, such as financial information, medical records, or government-issued ID numbers. Non-sensitive PII includes data that is easily accessible from public sources and does not pose a high risk of identity theft, such as zip code, race, or gender. A credit card number is a sensitive PII because it can be used to access the cardholder’s account, make fraudulent transactions, or steal their identity. Therefore, it is important to prevent credit card numbers from leaving the enterprise network, where they could be intercepted by hackers, malicious insiders, or third parties. To protect credit card numbers and other sensitive PII, enterprises should implement data security measures such as encryption, tokenization, masking, access control, auditing, and monitoring. Additionally, enterprises should comply with data privacy laws and standards that regulate the collection, use, and protection of PII, such as the Payment Card Industry Data Security Standard (PCI DSS), the General Data Protection Regulation (GDPR), or the California Consumer Privacy Act (CCPA). References:

Security Operations (SecOps) is the process of coordinating and aligning security teams and IT teams to improve the security posture of an organization. SecOps involves implementing and maintaining security controls, technologies, policies, and procedures to protect the organization from cyber threats and incidents. When dealing with a known attack, SecOps must take the following action: document, monitor, and track the incident. This action is important because it helps SecOps to:

•Record the details of the attack, such as the source, target, impact, timeline, and response actions.

•Monitor the status and progress of the incident response and recovery efforts, as well as the ongoing threat activity and indicators of compromise.

•Track the performance and effectiveness of the security controls and technologies, as well as the lessons learned and improvement opportunities. References:
