Cortex XSOAR enhances Security Operations Center (SOC) efficiency with the world’s most comprehensive operating platform for enterprise security. Cortex XSOAR unifies case management, automation, real-time collaboration, and native threat intel management in the industry’s first extended security orchestration, automation, and response (SOAR) offering.

"In serverless apps, the developer uploads only the app package itself, without a full container image or any OS components. The platform dynamically packages it into an image, runs the image in a container, and (if needed) instantiates the underlying host OS and VM and the hardware required to run them."

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:

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.

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

List three advantages of serverless computing over

CaaS: - Reduce costs - Increase agility - Reduce operational overhead

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

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.

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.

Forensics in a Security Operations process refers to collecting raw data needed to complete the detailed analysis of an investigation. Forensic analysis is a crucial step in identifying, investigating, and documenting the cause, course, and consequences of a security incident or violation. Forensic analysis involves various techniques and tools to extract, preserve, analyze, and present evidence in a structured and acceptable format. Forensic analysis can be used for legal compliance, auditing, incident response, and threat intelligence purposes. References:
