Cyberattacks is a generic term that includes a large number of possible threats. The most popular ones are:
In turn, cybersecurity includes the processes and techniques used to protect sensitive data, computer systems, networks and software applications from cyber attacks.
In this review, we will look at the most common types of attacks in our practice.
A botnet is a group of devices, most often hacked and infected with malware, in order to perform the task of cybercriminals. Botnets were originally designed to perform specific tasks within their group.
Types of botnet attacks:
Botnet attacks tend to target large enterprises and organizations that store large amounts of data. Such attacks allow you to simultaneously hack a large number of devices. You can secure your resource by filtering traffic from DDoS attacks.
Sometimes it is not enough to protect the resource itself from the botnet. For example, if we are talking about a site, then the databases can be well protected. But the domain name of the site is usually located on a server separate from the databases, which can also be attacked. In this case, you should take care in advance to protect your DNS server from malicious traffic.
At the heart of the mechanism for protecting the DNS protocol is forced switching from UDP to TCP for data validation. Switching occurs automatically - special software interferes with the session between the client and the protected server. It is important that this process does not cause noticeable delays to end users.
The interception of clients' personal data can occur at the time of their requests to the site: filling out payment forms, questionnaires, etc. Today they use SSL encryption to protect such traffic. The site owner buys and installs a special certificate, and then sets up a redirect from HTTP to the HTTPS address of his site.
But encrypted traffic can also contain malware (malicious code) or suspicious requests. There is a technology to clean it - HTTPS filtering. HTTPS traffic directed to the client's protected site is decrypted on our network for analysis and filtering to block suspicious data packets. The cleaned, secure traffic is then encrypted back and redirected to the client site.
To effectively implement a cybersecurity strategy within a particular organization, all parts of that organization, including people, processes, computers, networks and technology, must have an equal responsibility. If all components complement each other, any cyberthreats and attacks can be resisted.
The above botnet and DNS attacks are related to network security at L3-4 transport layers, interception of unencrypted data - to the L7 application layer. The market offers different solutions for each level: firewalls, DNS server protection, SSL certificates.
However, integrating these services separately and maintaining them can be resource intensive on the part of the owner of the system that needs protection. For example, you need to hire an IT specialist and hope that he is equally well versed in all the technologies that will be used. Or rely on the literacy of the technical support specialists of the supplier company and their high speed of response in case of incidents.
Today, in order to minimize the risks of cyber attacks and the cost of resources to eliminate their consequences, machine learning is used to ensure cybersecurity. Engineers develop algorithms for self-learning intelligent systems, which then work in automatic mode. Such systems instantly calculate and eliminate cyber threats 24/7, without wasting time and resources of IT specialists.
