Defending your system against DNS attacks

HomeBe up to date in techDefending your system against DNS attacks

DNS has become one of the easiest targets for cyber criminals. Although organisations sometimes seem neglectful about this matter, DNS attacks can have dramatic consequences on their company. This is the reasons why organisations must be prepared to face these new sophisticated attacks.

The disastrous consequences of DNS attacks

DNS is a critical component to ensure the good functioning of IT systems- without DNS, it becomes impossible to use the internet. DNS attacks are becoming more sophisticated, and therefore more difficult to detect and prevent. More than being extremely costly, DNS attacks can have other damaging consequences; here are the main consequences that companies may fear when not properly securing the DNS server:

  • Data theft;
  • Compromised website;
  • Business downtime;
  • Compromised public image (damage to the company’s brand or reputation).

In case of data theft, organisations may even face financial and legal consequences. You can go on to find a good protection. Recently, however, companies have been starting to look beyond traditional security systems. Every company can be a potential target to DNS attacks- especially DNS-based malware, phishing or tunnelling. These have become common data breaches that hackers and cyber criminal manage to use in order to access your sensitive data.

More efforts need to be done concerning the protection of network services, however. With the introduction of General Data Protection Regulation (GDPR), we can only hope that the situation will improve, and that organisations will do their utmost to prevent DNS attacks.

The reasons why cyber security has become a priority

Most organisations are aware of what has to be done to prevent DNS attacks, but are simply not doing it, even though highly sensitive data are at stake. However, everyone remembers the scandal of the British consulting firm Cambridge Analytica, which misused Facebook user’s data. The problem is not only how companies use customer data, but also what solutions they actually implement to efficiently protect them. Here are the reasons why cyber security is likely to become a priority for organisations in a near future:

  • With GDPR, protecting data has become a priority for businesses, which realise how important it is to protect sensitive data and to offer a better protection of confidential data.
  • The growing number of cyberattacks force businesses to protect their network; DDoS attacks can be carried out easily with a massive number of connections, and hide more dangerous threats.
  • Connected devices will become the next target of DNS attacks, and IoT devices could be used as vehicles to perform one.
  • Hacking has become a real matter of concern for businesses as DNS attacks become more common. Companies will need to enforce their systems by implementing new measures, such as white-hat-hacking.

Cyberattacks are evolving faster than ever, and 2018 marks a turning point in cyber criminality. Companies need to be ready to face new sophisticated threats involving serious consequences, such as data loss or brand damage.
