Cyberattacks are a generalized term that includes a large number of possible threats. Here are the most popular ones:
Cybersecurity, in turn, includes the processes and methods that are 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, to perform the task of attackers. Initially, botnets were designed to perform specific tasks within their group.
Types of botnet attacks:
Botnet attacks typically target large businesses and organizations that store large amounts of data. Such attacks allow you to simultaneously hack a large number of devices. You can protect your resource by filtering traffic from DDoS attacks.
Protecting the resource itself from a botnet is sometimes not enough. 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 separate server from the databases, which can also be attacked. In this case, you should take care of protecting the DNS server in advance from malicious traffic.
The DNS protocol protection mechanism is based on forced switching from the UDP protocol to the TCP protocol to allow 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 for end users.
Interception of personal data of clients can occur at the time of their requests to the site: filling out payment forms, questionnaires, etc. To protect such traffic today, SSL encryption is used. The site owner buys and installs a special certificate, and then sets up a redirect from HTTP to the HTTPS address of their site.
But encrypted traffic can also contain malware (malicious code) or suspicious requests. To clear it, there is a technology - HTTPS filtering. HTTPS traffic sent to the client's protected site is decrypted on our network for analysis and filtering to block suspicious data packets. After that, the cleared secure traffic is encrypted back and redirected to the client site.
To effectively implement a cybersecurity strategy within a particular organization, all parts of that organization, including employees, processes, computers, networks, and technologies, must be held equally accountable. If all the components complement each other, you can resist any cyber threats and attacks.
The above-described attacks by botnets and on DNS relate to network security at the transport layers L3-4, interception of unencrypted data - to the application layer L7. The market offers different solutions for each level: firewalls, DNS server protection, and SSL certificates.
However, integrating these services individually and maintaining them may require a lot of resources 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 competence of the technical support specialists of the supplier company and their high reaction speed in the event 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 the time and resources of IT specialists.
