Paloalto Networks PCCET Exam With Confidence Using Practice Dumps

● Application (Layer 7 or L7): This layer identifies and establishes availability of communication partners, determines resource availability, and synchronizes communication.

● Presentation (Layer 6 or L6): This layer provides coding and conversion functions (such as data representation, character conversion, data compression, and data encryption) to ensure that data sent from the Application layer of one system is compatible with the Application layer of the receiving system.

● Session (Layer 5 or L5): This layer manages communication sessions (service requests and service responses) between networked systems, including connection establishment, data transfer, and connection release.

● Transport (Layer 4 or L4): This layer provides transparent, reliable data transport and

end-to-end transmission control.

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

MITRE is a not-for-profit organization that operates research and development centers sponsored by the federal government. MITRE maintains the Common Vulnerabilities and Exposures (CVE) catalog, which is a dictionary of common names for publicly known cybersecurity vulnerabilities. CVE’s common identifiers, called CVE Identifiers, make it easier to share data across separate network security databases and tools, and provide a baseline for evaluating the coverage of an organization’s security tools12. References:
