Prisma SaaS connects directly to the applications themselves, therefore providing continuous silent monitoring of the risks within the sanctioned SaaS applications, with detailed visibility that is not possible with traditional security solutions.

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

Prisma SaaS is a cloud access security broker (CASB) solution that helps secure and manage SaaS applications. It provides advanced capabilities in risk discovery, data loss prevention, compliance assurance, data governance, user behavior monitoring, and advanced threat prevention12. The three services that are part of Prisma SaaS are:

Data Loss Prevention: This service helps prevent the leakage or exposure of sensitive data stored in SaaS applications. It allows you to define data patterns, policies, and actions to protect your data from unauthorized access or sharing3.

Data Exposure Control: This service helps identify and remediate data exposure risks in SaaS applications. It scans your data at rest and classifies it based on its sensitivity and exposure level. It also provides recommendations and remediation actions to reduce the risk of data breaches4.

Threat Prevention: This service helps detect and block malicious activities and threats in SaaS applications. It leverages the WildFire and AutoFocus threat intelligence services to analyze user and file activity and identify indicators of compromise. It also provides alerts and response actions to mitigate the impact of threats5.

 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:

Log normalization – SIEMs standardize log formats from various sources, making it easier to analyze and correlate security events.

Incident response – Integration enables faster detection, investigation, and automated or guided response to security incidents by using correlated data from multiple tools.

Hardware procurement and security team training are not directly influenced by SIEM integration.

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:

A perimeter-based network security strategy relies on firewalls, routers, and other devices to create a boundary between the internal network and the external network. This strategy assumes that every internal endpoint can be trusted, and that any threat comes from outside the network. However, this assumption is flawed, as internal endpoints can also be compromised by malware, phishing, insider attacks, or other methods. Once an attacker gains access to an internal endpoint, they can use it to move laterally within the network, bypassing the perimeter defenses. Therefore, a perimeter-based network security strategy is not sufficient to protect an organization’s endpoint systems, and a more comprehensive approach, such as Zero Trust, is needed. References:

"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."

An application allow list prevents malware from executing by only permitting approved applications to run on an endpoint. Any unauthorized or unknown software, including malicious programs, is automatically blocked from executing.

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.
