Which incidence response step includes identifying all hosts affected by an attack?
Answer: D
Explanation:
* 3.3.3 Identifying the Attacking Hosts During incident handling, system owners and others sometimes want to or need to identify the attacking host or hosts.
Although this information can be important, incident handlers should generally stay focused on containment, eradication, and recovery.

The response phase, or containment, of incident response, is the point at which the incident response team begins interacting with affected systems and attempts
to keep further damage from occurring as a result of the incident.

Explanation:
Delivery: This step involves transmitting the weapon to the target.
Weaponization: In this step, the intruder creates a malware weapon like a virus, worm or such in order to exploit the vulnerabilities of the target. Depending on the
target and the purpose of the attacker, this malware can exploit new, undetected vulnerabilities (also known as the zero-day exploits) or it can focus on a
combination of different vulnerabilities.
Reconnaissance: In this step, the attacker / intruder chooses their target. Then they conduct an in-depth research on this target to identify its vulnerabilities that
can be exploited.

Answer: D
A. AWS
B. IIS
C. Load balancer
D. Proxy server
Answer: C
Explanation:
Load Balancing: HTTP(S) load balancing is one of the oldest forms of load balancing. This form of load balancing relies on layer 7, which means it operates in the
application layer. This allows routing decisions based on attributes like HTTP header, uniform resource identifier, SSL session ID, and HTML form data.
Load balancing applies to layers 4-7 in the seven-layer Open System Interconnection (OSI) model. Its capabilities are: L4. Directing traffic based on network data
and transport layer protocols, e.g., IP address and TCP port. L7. Adds content switching to load balancing, allowing routing decisions depending on characteristics
such as HTTP header, uniform resource identifier, SSL session ID, and HTML form data. GSLB. Global Server Load Balancing expands L4 and L7 capabilities to
servers in different sites
A. online assault
B. precursor
C. trigger
D. instigator
Answer: B
Explanation:
A precursor is a sign that a cyber-attack is about to occur on a system or network. An indicator is the actual alerts that are generated as an attack is happening.
Therefore, as a security professional, it's important to know where you can find both precursor and indicator sources of information.
The following are common sources of precursor and indicator information:
Security Information and Event Management (SIEM)
Anti-virus and anti-spam software
File integrity checking applications/software
Logs from various sources (operating systems, devices, and applications)
People who report a security incident https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-61r2.pdf
