Security Operations Center (SOC)
Analysts play a crucial role in identifying, analyzing, responding, and
mitigating cyber attacks in an organization. The Tier 1 SOC Analysts are
triaged, which means the first responders who identify, manage, and configure the
security tools to analyze and define the nature of the attack. This article
provides the interview questions for SOC Analysts L1 and helps to take a quick
revision before cracking an interview.
1. What
is a threat?
A Threat is defined as a
malicious activity intended to achieve unauthorized access to the system,
disrupt the organization's assets, steal data, and damage the network
operation.
The threats are categorized into the following types:
- Adversarial Threat
- Accidental Threat
- Environmental Threat
- Structured Threat
2. What
is vulnerability?
Vulnerability is a weakness or security flaw in a system or network that allows attackers to exploit the system and can lead to unauthorized access, malware injection, DDoS attacks, or data compromise. It creates a possible way to violate the system's security policy.
3. Explain
the difference between event and incident.
An event is an occurrence in time that is analyzed, verified, and documented. An incident is a series of events that negatively affect organizational assets.
4. How
is Incident management different from Problem management?
Incident Management is defined as minimizing the negative impact of incidents by restoring security operations. In contrast, problem management is defined as the cause of one or more incidents that further deals with identifying the root cause of an incident.
5. Define
a Brute force attack and a Dictionary attack.
In a Brute force attack,
several possible key permutations or trial and error methods are used to get
the login info, access to a web page, or encryption keys. Whereas, in a
Dictionary attack, words are used to break the password-protected network,
system, or IT resource.
6. What
are the various types of Brute Force Attacks?
The following are the various types of Brute Force Attacks:
- Credential Stuffing
- Dictionary Attack
- Simple Brute Force Attack
- Hybrid Brute Force Attack
- Reverse Brute Force Attack
- Rainbow Table Attack
7. What
is the difference between DOS & DDOS?
DOS is a Denial of Service attack in which the attackers send an enormous amount of traffic to make the server or website services unavailable. In contrast, the DDoS attack is a Distributed denial-of-service that uses multiple systems to inject massive traffic into the target system. Both DoS and DDoS attacks aim to interrupt the services provided by the websites.
8. What
are the various types of DDoS attacks?
The various types of DDoS attacks are as follows:
- Application Layer Attacks
- Fragmentation Attacks
- Protocol Attacks
- Volumetric Attacks
9. Define
Firewall, and what are the different types of firewalls?
A Firewall is a security
solution used to protect the network from malicious activities. It is connected
with the systems or devices through a network to monitor the network traffic.
Different types of firewalls are as follows:
- Packet-filtering firewall
- Cloud firewall
- Application layer firewall
- Stateful Inspection firewall
- Hardware firewall
- Software firewall
10. What
is WAF?
A Web Application Firewall
(WAF) protects the web application from cyberattacks such as cookie poisoning,
Cross-site scripting, SQL injection, etc.
