A stateless firewall is a network firewall that primarily filters traffic based on source and destination IP address, as well as port numbers and protocols. A stateless firewall does not keep track of the state or context of network connections, and only inspects packet headers. A stateless firewall is faster and simpler than a stateful firewall, but it is less secure and flexible. A stateless firewall cannot block complex attacks or inspect packet contents for malicious payloads.Reference:What Is a Packet Filtering Firewall? - Palo Alto Networks,Common IP Filtering Techniques -- APNIC,What is IP filtering? - Secure Network Traffic Management

IDSs and IPSs also can be classified as knowledge-based (or signature-based) or behavior-based (or statistical anomaly-based) systems:

A knowledge-based system uses a database of known vulnerabilities and attack profiles

to identify intrusion attempts. These types of systems have lower false-alarm rates than

behavior-based systems but must be continually updated with new attack signatures to

be effective.

A behavior-based system uses a baseline of normal network activity to identify unusual

patterns or levels of network activity that may be indicative of an intrusion attempt.

These types of systems are more adaptive than knowledge-based systems and therefore

may be more effective in detecting previously unknown vulnerabilities and attacks, but they have a much higher false-positive rate than knowledge-based systems

Cybercriminals are attackers who act independently or as part of an unlawful organization, such as a crime syndicate or a hacker group. Their main motivation is to make money by exploiting vulnerabilities in systems, networks, or applications. They use various methods, such as ransomware, phishing, identity theft, fraud, or botnets, to steal data, extort victims, or disrupt services. Cybercriminals often target individuals, businesses, or institutions that have valuable or sensitive information, such as financial, personal, or health data. Cybercriminals are constantly evolving their techniques and tools to evade detection and countermeasures. They may also collaborate with other cybercriminals or hire hackers to perform specific tasks.Reference:

Endpoint antivirus software is a type of software designed to help detect, prevent, and eliminate malware on devices, such as laptops, desktops, smartphones, and tablets. Endpoint antivirus software can block viruses that are not seen and blocked by the perimeter firewall, which is a network security device that monitors and controls incoming and outgoing network traffic based on predefined security rules. Perimeter firewall can block some known viruses, but it may not be able to detect and stop new or unknown viruses that use advanced techniques to evade detection.Endpoint antivirus software can provide an additional layer of protection by scanning the files and processes on the devices and using various methods, such as signatures, heuristics, behavior analysis, and cloud-based analysis, to identify and remove malicious code123.Reference:

Cortex XDR is an endpoint product from Palo Alto Networks that can help with SOC visibility by allowing you to rapidly detect and respond to threats across your networks, endpoints, and clouds. It assists SOC analysts by allowing them to view all the alerts from all Palo Alto Networks products in one place, and to perform root cause analysis and automated response actions.Cortex XDR also integrates with other Palo Alto Networks products, such as WildFire, AutoFocus, and Cortex Data Lake, to provide comprehensive threat intelligence and data enrichment12.Reference:
