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.

HTTPS is a protocol that encrypts and secures the communication between web browsers and servers. HTTPS uses SSL or TLS certificates to establish a secure connection and prevent unauthorized access or tampering of data. HTTPS typically uses port 443, which is the default port for HTTPS connections. Port 443 is different from port 80, which is the default port for HTTP connections. HTTP is an unencrypted and insecure protocol that can expose sensitive information or allow malicious attacks. Port 443 is also different from port 5050, which is a common port for some applications or services, such as Yahoo Messenger or SIP. Port 5050 is not associated with HTTPS and does not provide any encryption or security. Port 443 is also different from port 25, which is the default port for SMTP, the protocol used for sending and receiving emails. Port 25 is not associated with HTTPS and does not encrypt the email content or headers. References:

Prisma Cloud comprises four pillars:

● Visibility, governance, and compliance. Gain deep visibility into the security posture of

multicloud environments. Track everything that gets deployed with an automated asset

inventory, and maintain compliance with out-of-the-box governance policies that

enforce good behavior across your environments.

● Compute security. Secure hosts, containers, and serverless workloads throughout the

application lifecycle. Detect and prevent risks by integrating vulnerability intelligence into

your integrated development environment (IDE), software configuration management

(SCM), and CI/CD workflows. Enforce machine learning-based runtime protection to

protect applications and workloads in real time.

● Network protection. Continuously monitor network activity for anomalous behavior,

enforce microservice-aware micro-segmentation, and implement industry-leading

firewall protection. Protect the network perimeter and the connectivity between

containers and hosts.

● Identity security. Monitor and leverage user and entity behavior analytics (UEBA) across

your environments to detect and block malicious actions. Gain visibility into and enforce

governance p

A SASE solution converges networking and security services into one unified, cloud-delivered solution (see Figure 3-12) that includes the following:

● Networking

○ Software-defined wide-area networks (SD-WANs)

○ Virtual private networks (VPNs)

○ Zero Trust network access (ZTNA)

○ Quality of Service (QoS)

● Security

○ Firewall as a service (FWaaS)

○ Domain Name System (DNS) security

○ Threat prevention

○ Secure web gateway (SWG)

○ Data loss prevention (DLP)

○ Cloud access security broker (CASB)

The basic DNS record types are as follows:

● A (IPv4) or AAAA (IPv6) (Address): Maps a domain or subdomain to an IP address or

multiple IP addresses

● CNAME (Canonical Name): Maps a domain or subdomain to another hostname

● MX (Mail Exchanger): Specifies the hostname or hostnames of email servers for a domain

● PTR (Pointer): Points to a CNAME; commonly used for reverse DNS lookups that map an

IP address to a host in a domain or subdomain

● SOA (Start of Authority): Specifies authoritative information about a DNS zone such as

primary name server, email address of the domain administrator, and domain serial

number

● NS (Name Server): The NS record specifies aan authoritative name server for a given host.

● TXT (Text): Stores text-based information

The diagram displays a mesh topology, where each device is connected to every other device in the network. This topology is characterized by the multiple connections each node has, ensuring there is no single point of failure and providing redundant paths for data transmission, enhancing the reliability and resilience of the network. Mesh topology is one of the types of LAN technology that uses ethernet or Wi-Fi to connect devices12. 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:

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

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:

Knowledge-based systems and behavior-based systems are two types of artificial intelligence systems that can be used for security purposes. Knowledge-based systems use a predefined database of rules, facts, and patterns that distinguish “bad” or malicious activities from normal ones. They compare the incoming data with the stored knowledge and flag any anomalies or matches. Behavior-based systems, on the other hand, learn from the observed data and establish a baseline of normal behavior. They then monitor the data for any deviations or changes from the baseline and alert on any suspicious or abnormal activities. References:
