Navigating the vast realm of cyber threats can seem daunting, and the risk and impact of cyber threats continue to rise as we become more increasingly linked in this digital age. In this blog, we will be investigating what is Denial of Service (DoS) attack.
In the points below, we’ll walk you through what a Denial of Service attack means, and reveal effective strategies to mitigate this threat.
A DoS attack, at its core, is a method employed by cyber criminals to disrupt a network, service, or server. The attacker seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the internet. The attacker achieves this by overwhelming the target with a flood of internet traffic, causing a shutdown of services and leaving legitimate users in a state of “denial of service”.
One can liken a DoS attack to a massive crowd storming a physical store. The crowd, in this analogy, does not intend to shop but to occupy all the available space, making it impossible for legitimate customers to enter or shop effectively.
DoS attacks come in different forms, and they can be as diverse as the cyber adversaries who use them. The most common type is the Distributed Denial of Service (DDoS) attack, where multiple compromised computers are used to target a single system. This distributed approach magnifies the attack’s effect, making it even more challenging to defend against.
The consequences of a successful DoS attack can be far-reaching, disrupting business operations, damaging reputations, and causing financial losses. Moreover, these attacks often serve as a smoke screen for more sinister activities, such as data breaches and malware installation, making their threat landscape even more complex.
Defending against a DoS attack requires a robust, multi-layered strategy. At Infotrust, we believe an effective defence strategy should incorporate regular penetration testing. By conducting these “friendly” attacks on your systems, you can identify weak points and address them before cyber criminals can exploit them.
We also advocate for regular awareness training. DoS attacks, like many other forms of cyber threats, often exploit human vulnerabilities – therefore, educating your team on recognising and handling potential threats is paramount. Awareness training helps your users understand the danger of DoS attacks and identify and report suspicious activity.
Additionally, we recommend a proactive approach to cybersecurity that starts with comprehensive incident response planning. Being prepared and knowing how to react when an attack occurs significantly reduces the potential damage.
Understanding what a Denial of Service attack is, its potential impacts, and how to defend against it are critical first steps on the path to robust cyber security. At Infotrust, we’re here to help guide you on this journey, providing the tools, knowledge, and expertise to navigate the cyber threat landscape. With our extensive suite of cyber security services, your organisation can turn the tide against DoS attacks and other cyber threats, ensuring your organisation is secure and compliant.
