Here are the top 16 interview questions on cyberattacks for today. The following are frequently asked questions for both new and experienced candidates for a cyber security certification.
- What is DDoS? …
- What are the main categories of DDoS attacks? …
- Why do companies use DDoS attack protection to safeguard against DDoS attacks? …
- What’s your understanding of a botnet? …
- Can you explain what a reflection attack is and how it works?
DDOS RealTimeScenario
A. Their primary distinction is that volumetric attacks target IT infrastructure. Most often, network devices are the first targets of such attacks, with any legitimate traffic being blocked and the total bandwidth being quickly consumed.
A: The quick response is that attacks will keep getting bigger. A significant DDoS back in the year 2000 was 100 Mbps (megabits per second). A significant attack last June was measured at 470 Gbps (gigabits per second). Within the next five years, I predict that we will witness the first 1 Tbps attack. Additionally, I believe that DDoS attacks will continue to transition from unorganized attacks by lone wolves to more coordinated attacks by hacktivists and criminal gangs. Last but not least, I think the attacks on financial institutions will worsen. Currently, the goal of these attacks is to embarrass or extort cash, but I anticipate targeted DDoS attacks that interfere with systems for financial transactions and harm financial markets.
A: They are similar in some ways. Both evaluate your resources to find problems before an attacker does. The primary distinction is that vulnerability scans look for potential points where an attacker could access your data. Usually this is through software bugs or misconfigurations. A DDoS risk assessment looks for areas where a DDoS attack is more likely to occur. For instance, a website’s login form might be extremely secure, but due to shoddy coding, it could be quickly attacked and taken offline.
A: Incapsula offers a comprehensive defense against a variety of DDoS attacks to safeguard websites and other assets. The solution is entirely cloud-based, and our service can be set up with just a few DNS server configuration changes. Traffic is diverted to our firewall once the service is configured before it reaches the origin server. Using a complex set of rules and challenges, our WAF filters DDoS traffic to determine whether an incoming request is coming from a malicious bot or a legitimate client trying to access a web server. You can find a more detailed answer on our website.
A single bot was all it took in our demonstration to bring down a single database. But it is true that the more resources required to bring down a web application, the more capacity it has. That’s why attackers will make botnets as large as possible.

There are two sections to this blog post on cybersecurity interview questions: Part A covers theoretical cybersecurity interview questions, and Part B covers scenario-based cybersecurity interview questions.
3. Application Layer Attacks: GET/POST floods, low-and-slow attacks (such attacks can be conducted using Slowloris and RUDY), etc. are examples of this type of attack. Here, the attacker takes advantage of how the TCP protocol functions to send the victim brief TCP packets at regular intervals. The resource waits for another packet after receiving it until a certain cut-off time. Just before the deadline, the attacker sends another packet. Hence, again waiting happens. Possible mitigation strategies include increasing server resources, managing numerous requests, preventing proxy-based connections, etc. , are some mitigation techniques for application-layer attacks.
DDoS attack types and potential mitigation strategies were covered in this article. I attempt to summarize both attack types and mitigations even though I am not covering them in-depth. We have also discussed well-known DDoS attacks from the past, like Mirai, which just occurred in 2017
2. Protocol Attacks: Ping of Death, Smurf DDoS, fragmented packet attacks, SYN floods (a TCP vulnerability), etc. , are examples of protocol attacks. It is basically exploiting the server resources of the victim. Possible mitigation strategies include rate limiting, checking packets for RFC compliance, using threshold timings to wait for the connection to complete, and detecting fake patterns using AI techniques. , are some of the techniques for mitigation.
1. Volume-Based Attacks: Using various tools or BOT machines, the attacker floods the victim with network packets in this type of attack. This kind of flood includes instances such as UDP floods, ICMP floods, and other spoofed-packet floods. Possible DDoS mitigation strategies: One of the DDoS mitigation strategies is rate limiting of various types of network packets. Other mitigations include blocking the IP address of the attacker or a range of IP addresses (for a while as it might be a spoof), using machine learning algorithms to identify fake traffic, blocking tor IPs, etc.
One of the most pervasive and sophisticated cyberattacks in the world is the Distributed Denial of Service (DDoS) attack. malicious users try to prevent legitimate users from accessing the victim company’s online services. It is also considered a deadly weapon against online businesses. These days, hackers can also launch attacks against networks of organizations by using cloud services. DDoS attacks were also used as a weapon by various government organizations to disrupt the operations of the adversary nation.
What is a Distributed Denial of Service attack (DDoS)?
DDoS attacks are malicious attempts to overload networks and systems with traffic in order to consume bandwidth and other resources. A distributed denial of service (DDOS) attack is what this is known as when hackers use multiple systems to launch this assault.
FAQ
What are the 3 types of DDoS attacks?
- Application layer attacks. The server creates the response to an incoming client request at the application layer.
- Protocol attacks. …
- Volumetric attacks.
What is the most common DDoS attack?
Application layer attacks, protocol attacks, and volumetric attacks are the three main categories of DDoS attacks. They occur at different layers of the OSI model.
What is the best attack method for DDoS?
- UDP flood.
- ICMP (Ping) flood.
- SYN flood.
- Ping of Death.
- Slowloris.
- NTP Amplification.
- HTTP flood.
What OSI layer is DDoS?
The OSI Model’s Layer 7 is the layer that sits above the other 6 layers and directly below the user interface surface. Data is presented in this layer in a way that user-facing applications can use it. DDoS attacks often take place on layer 7.
