When you are an IT analyst or director of a company, it is important to make some important network control and security decisions. 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 aimed at harming organizations is increasing. Therefore, it is important that professionals in the field have knowledge of tools that can help block these attacks to avoid loss of information, productivity and money.
Furthermore, the budget for investment in network security and internet control is always limited in most small and medium-sized companies. Therefore, it is necessary to study the entire network scenario, act quickly and find an integrated solution to improve digital security without spending excessively and without burdening the team's productivity.
One of the most important parts of the network, as it is most often the gateway to attacks, is the DNS layer. And with an integrated solution, which uses data intelligence and studies the reputation of each website, it is possible to identify and block malicious websites in advance, such as access anonymizers, hacking, keyloggers, malware, spyware, phishing and fraud. In this way, a solution that helps protect the DNS layer of a company's network becomes the first line of defense, since DNS requests precede all activities on the internet.
Main types of attacks at the DNS layer
It's not just companies that create security solutions that are innovative. Cybercriminals, by necessity, also innovate aggressively by trying to find loopholes in organizations' security products and policies.
But in recent years, criminals have become more motivated and ambitious due to the increasing financial rewards from happy-ending attacks. As digital media is increasingly used, generating a lot of important information, the data of these companies becomes valuable and the main target of these criminals. If this data is stolen, it can be resold in the open on the internet for a very significant amount. Another type of attack is ransomware , which is increasingly common, which forces the organization to pay for access to its own information.
The most common DNS attack techniques cause the user to try to access a certain page and be redirected to an incorrect destination. These techniques are called cache poisoning (DNS Poisoning) and server hijacking (DNS Hijacking).
The DNS Poisoning attack occurs when a criminal manages to infiltrate the DNS server, with the aim of modifying the information recorded in the cache and thus changing the destination IP number, without having to change the address that the user types in the browser.
In the DNS Hijacking attack, the criminal uses malware with the aim of hijacking domain translation requests and redirecting traffic to a malicious DNS server.
The difference between the two techniques is that the criminal's focus in the first (DNS Poisoning) is the DNS server and the second (DNS Hijacking) is the device itself (computer, laptop).
The malicious pages to which the user may be directed are, in general, cloned (a phishing ) with the aim of spreading malware payloads or unwanted applications, mining cryptocurrencies, stealing information on falsified access forms, etc. And as the user entered the correct domain, it will be difficult for them to quickly identify that they were a victim of this type of engineering.
Advantages of DNS Layer Control
A solution for controlling DNS requests brings many advantages to companies, including the following:
-
- Security internet access control solution it is possible to proactively protect against emerging threats. These solutions are equipped with services that have constantly updated lists of suspicious websites. Another important feature is the possibility of defining the necessary level of reputation that a website must have to be accessible on the network, blocking it if the level is lower than that configured.
- Productivity : Improper use of the internet by employees can greatly compromise the company's productivity. This waste of time can occur in countless ways, accessing social networks such as Facebook or Instagram, accessing personal email, communication services such as WhatsApp or Skype, entertainment websites, shopping, sports, among others. However, an internet access control solution also allows the blocking of unwanted websites that are outside the company's scope of work and that waste employees' time and compromise productivity.
- Cost reduction : With increased network security, reduced equipment maintenance costs and increased team productivity, the investment in an internet access control solution often pays for itself in the first few months.
- Information : Another important point is collecting information about internet use, having reports on what is being accessed and analyzing this information in conjunction with reports on team productivity and task delivery, this can lead to the optimization of your access policy to Internet.
Tools to increase network security
As the DNS layer is the gateway to the main cyber attacks on a company's network, implementing a tool to increase security becomes an essential factor in ensuring information security.
By preemptively blocking all requests on any port or protocol, security at the DNS layer can stop the action and avoid the burden of needing to identify the specific source of that attack.
To increase network security in your company, there are different alternatives, such as traditional Linux proxy solutions provided by specialized companies, which require greater investment in servers, specialized labor and constant maintenance.
Other options are SonicWall , Fortinet FortiGate and similar, or more modern solutions that use cloud resources and are more accessible, easy to implement and manage. This type of service is mainly recommended for small and medium-sized companies, good options are Lumiun , OpenDNS or DNSFilter .
