In today’s ever-increasing cyber world, vulnerability is one of the key factors that calls for swift and impactful analysis. In the immediate past we have seen how vulnerable and attack-prone the cyber world has become – From a host of ransomware attacks on multiple countries, leaked episodes of HBO’s Game of Thrones thronging the internet, the entire Heathrow airport locked down because of a cyber-attack – no system in the world is immune. This is because with the evolution of technology comes its loopholes in terms of lack of security features, robustness etc. One of the key armament of cyber attackers is DOS or Denial of Service – DDoS or Distributed Denial of Service being the ace weapon in the quiver.
Before we move on to the emerging DDoS trends, let us first understand the meaning of Denial of Service (DoS) and Distributed Denial of Service (DDoS). Only if we are aware of the problem and its whereabouts, can we be better equipped to handle it.
Denial of Service (DOS):
A Denial of Service or DoS attack is a cyber-attack in which the perpetrator happens to make a machine or a network unavailable to the user by temporarily disrupting the services of a host connected to the internet. Typically achieved by flooding the target with superfluous and malicious content thereby overloading the system and eventually blocking the fulfillment of some or all of the legitimate requests.
Distributed Denial of Service (DDoS):
In a DDoS, the incoming traffic is generated from a distributed source of multiple systems thereby rendering it virtually impossible to track down and block the requests attacking the system.
Now that we have a basic idea as to what DoS and a DDoS are, it is time to discuss how these attacks are manifested by the perpetrators to spell doom for organizations across the world.
Types of DDoS attacks:
Potential Targets: There is no defined target for the perpetrators of such attacks. Anyone from an apparently harmless domestic user to large organizations like banks & financial institutions as well as airports , space stations or defense facilities are prone to these attacks.
Mitigation Plan: Since these attacks are completely unforeseen and happens at the spur of a moment, there is no defined way that these could be stopped. However, world bodies have convened over the years and have formulated a basic health checklist, known as DDoS mitigation. Organizations are advised to implement DDoS mitigation plan through experts to thwart any such attacks over time. Individuals are advised to keep their financial details secure and not expose them to untrusted websites, mobile apps or any individual claiming to be an authorized bank-representative
