When you are a company's IT analyst or director, it is important to make some important decisions of network control and safety. Especially when the internet is the main tool for the company's full operation. If this responsibility were not enough, the volume and sophistication of cyber attacks that aim to harm organizations grow more and more. Therefore, it is relevant for professionals in the field to be aware of tools that can assist in blocking these attacks to avoid loss of information, productivity and money.
In addition, the network security investment budget and internet control is always limited to most small and medium -sized companies. Therefore, it is necessary to study the entire scenario of the network, act quickly and find an integrated solution to improve digital security without exceeding excessively and not overloading team productivity.
One of the most important parts in the network, because it is mostly the gateway to the attacks, is the DNS layer. And with an integrated solution, which uses data intelligence and studies the reputation of each site it is possible to identify and block malicious sites such as access anonymitors, hacking, keylogger, malware, spyware, phishing and fraud. Thus, a solution that helps protect the DNS layer from a company's network becomes the first line of defense, as DNS requests precede all activities on the Internet.
Main types of attacks on the DNS layer
It is not just companies that create safety solutions that are innovative. Cyber criminals, out of necessity, also aggressively innovate trying to find loopholes and safety policies of organizations.
But in recent years, criminals have become more motivated and ambitious due to the growing financial rewards arising from "happy" end attacks. As the digital environment is increasingly used, generating a lot of important information, the data of these companies become valuable and the main target of these criminals. If this data is stolen, it can be resold in the open field on the Internet for a very significant value. Another type of attack is increasingly common ransomware
The most common DNS attack techniques make the user try to access a certain page and be directed to an incorrect destination. These techniques are called cache poisoning (DNS) and server (DNS Hijacking).
The DNS Poisoning attack occurs when a criminal can infiltrate the DNS server, with the purpose of modifying the information recorded in the cache and thereby changing the destination IP number without changing the address the user types in the browser.
The DNS Hijacking attack, the criminal uses malware to kidnap domain translation requests and redirect traffic to a malicious DNS server.
The difference between the two techniques is that the focus of the criminal in the first (DNS poisoning) is the DNS server and the second (DNS hijacking) is the device itself (computer, laptop).
Malicious pages to whom the user can be directed are generally cloned (a phishing ) in order to disseminate malware loads or unwanted applications, mining cryptocurrencies, steal information on counterfeit access forms, etc. And as the user typed the correct domain, he will hardly identify agile that he was the victim of this type of engineering.
Advantages of DNS layer control
A solution for controlling DNS requests bring many advantages to companies, which we highlight the following:
-
- Safety internet access control solution, proactive protection against emerging threats can be made. These solutions are equipped with services that have constantly updated suspicious websites. Another important feature is the possibility of defining the necessary reputation level that a site must have to be accessible on the network, making the lock if the level is lower than the configured.
- Productivity : The misuse of the internet by employees can greatly compromise the productivity of the company. This waste of time can occur in countless ways, access to social networks such as Facebook or Instagram, access to personal email, communication services such as WhatsApp or Skype, entertainment sites, shopping, sports, among others. However, an Internet access control solution also allows blocking unwanted websites that are outside the company's scope and causing employee time waste and compromise productivity.
- Cost reduction : With increasing network safety, decreasing equipment maintenance costs and increasing team productivity, investment in an internet access control solution often pays in the first months.
- Information : Another important point is the gathering of information about the use of the internet, having reports of what is being accessed, and analyzing this information together with team productivity reports and task delivery, can lead to the optimization of your internet access policy.
Tools to increase network security
As the DNS layer is the door to major cyber attacks on a company's network, the implementation of a tool to increase security becomes an essential factor to ensure information security.
By preventively blocking all requests in any port or protocol, safety in the DNS layer can interrupt the action and avoid the burden of identifying the specific origin of that attack.
To increase network safety in your company, there are different alternatives, such as traditional proxy Linux solutions provided by specialized companies, which require greater investment with servers, specialized labor and constant maintenance.
Other options are Sonicwall , Fortinet Fortigate and the like, or more modern solutions that use cloud resources and are more affordable, easy to implement and management. This type of service is mainly recommended for small and medium businesses, good options are Lumiun , OpenDNS or DNSFilter .
