Similarly, what is cyber reconnaissance?
Cyber reconnaissance can be described as the monitoring, analysis, and countering cyber security threats. This type of cyber intelligence or cyber reconnaissance is a combination of physical espionage with defense using modern information technology.
You may also wonder what the difference is between active and passive reconnaissance. A fundamental difference in method is that active reconnaissance requires being present on a target server or network and leaving a trail, while passive reconnaissance focuses on being as untraceable possible.
You may also wonder, "What is the technique for reconnaissance attack?"
Reconnaissance attacks Examples include ICMP ping sweeps of a network or SNMP walks techniques to gather device configuration and network map data.
What is the difference between reconnaissance and footprinting?
Footprinting, also known as reconnaissance, is a technique for gathering information about computer systems. "Footprinting" is a term that is used in computer security terminology to refer to one of the preattack phases, tasks performed before the actual attack.

Why is reconnaissance an important step for an attacker?
Performing Reconnaissance
Reconnaissance is consideredthe first pre-attack phase and is a systematic attempt to locate, gather, identify, and record information about the target. Hackers can gather information in many different ways, and the information they obtain allows them to formulate a plan of attack.What is reconnaissance attack?

What are the types of network attacks?
There are different types of DoS and DDoS attacks; the most common are TCP SYN flood attack, teardrop attack, smurf attack, ping-of-death attack and botnets.
What is a DDoS attack on a server?
Distributed DoS attack. A distributed denial-of-service (DDoS) attack occurs when multiple systems flood the bandwidth or resources of a targeted system, usually one or more web servers. Such an attack is often the result of multiple compromised systems (for example, a botnet) flooding the targeted system with traffic.
Is NSLookup passive or active?
“Simply performing an NSLookup to search for an IP address is passive, but the moment you begin doing a zone transfer using some of these tools, you are beginning to do active reconnaissance”.

What is the difference between passive and active scanning?
What are passive and active scanning? During an active scan, the client radio transmits a probe request and listens for a probe response from an AP. With a passive scan, the client radio listens on each channel for beacons sent periodically by an AP.
Is banner grabbing active or passive?
There are two types of banner grabbing: active and passive. Identifying the OS used on the target host allows an attacker to figure out the vulnerabilities the system posses and the exploits that might work on a system to further carry out additional attacks.
