Session data is the data type that is necessary to get information about source/destination ports. Session data is the information about connections between hosts, such as IP addresses, ports, protocols, and duration. Session data can be used to identify the services and applications that are being used on the network, as well as the direction and volume of the traffic. Session data can also help to detect anomalous or malicious behavior, such as port scanning, brute force attacks, or data exfiltration. Session data can be collected from various sources, such as firewalls, routers, switches, or network monitoring tools. References:

The 5-tuple approach consists of protocol, source IP address, source port number, destination IP address, and destination port number to uniquely identify sessions between endpoints on a network. References := Cisco Cybersecurity Source Documents

 A TCP handshake is a three-way exchange of messages between a client and a server to establish a TCP connection. The client initiates the handshake by sending a SYN packet with a sequence number to the server. The server responds with a SYN-ACK packet with its own sequence number and an acknowledgment number that is the client’s sequence number plus one. The client completes the handshake by sending an ACK packet with an acknowledgment number that is the server’s sequence number plus one. If the remote server is not receiving an SYN-ACK packet from the local server, it means that the TCP handshake is not completed and the connection is not established. This could be causedby various factors, such as network congestion, firewall rules, packet filtering, or misconfiguration of the TCP parameters on either end. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 177; TCP 3-Way Handshake Process - GeeksforGeeks

 Input sanitization involves cleaning up user input before processing it, ensuring that it does not contain malicious code intended for buffer overflow attacks or other types of security breaches. References := New Cybersecurity Skills

The exhibit shows a SQL query that is attempting to bypass login controls by modifying the query to always return true. This is a common tactic used in SQL injection attacks where malicious SQL statements are inserted into an entry field for execution. References := Cisco Cybersecurity Source Documents

A man-in-the-middle attack is a type of cyberattack where an attacker intercepts and alters the communication between two parties who believe they are directly communicating with each other. In this case, the attacker is impersonating mail.google.com and presenting a fake certificate to the endpoint device. The endpoint device detects that the certificate is not issued by a trusted authority and displays an error message. The attacker can then monitor or modify the traffic between the endpoint device and mail.google.com. References:

Symmetric encryption is a type of encryption that uses the same key to encrypt and decrypt data. Asymmetric encryption is a type of encryption that uses a pair of keys: a public key and a private key. The public key can be used to encrypt data, but only the private key can decrypt it, and vice versa. An advantage of symmetric encryption over asymmetric encryption is that it is faster and more efficient for encrypting large amounts of data, such as in sessions or bulk transfers. Asymmetric encryption is slower and more computationally intensive, but it is more secure and suitable for key exchange or digital signatures. References := Cisco Cybersecurity Operations Fundamentals, Module 2: Security Monitoring, Lesson 2.3: Cryptography and PKI, Topic 2.3.1: Cryptography

Social engineering techniques often involve manipulating individuals into divulging confidential information or performing actions that compromise security. Phishing involves sending fraudulent messages (often emails) that appear to be from reputable sources with the goal of stealing sensitive data or installing malware. Pharming redirects the traffic of a legitimate website to another fraudulent website without the user’s knowledge, aiming to collect the user’s credentials. References := Cisco Cybersecurity Source Documents

 Behavior-based detection monitors the behavior of programs in real-time. If a piece of software acts similarly to known malware after it’s been executed, behavior-based detection can stop it in its tracks. Signature-based detection involves searching for known patterns of data within executable code; if a pattern matches a “signature” in the system’s database that is considered malicious. References: Cisco Cybersecurity Operations Fundamentals
