What Is Cyber-security? How to Protect Yourself From Hackers?

What is Cybersecurity? How to protect yourself from attacks by cybercriminals and hackers?

Ensuring cybersecurity in questions and answers. Cybersecurity in the usual sense is a set of measures aimed at minimizing the criminal actions of intruders (cybercriminals, hackers) on web resources, networks and software. All this is cybersecurity ( Wikipedia ). In the modern world of technology, the problem of attacks on businesses operating on the Internet has become extremely aggravated. Theft of personal data, theft of funds from the accounts of bank clients, destruction of websites (complete deletion or blocking) are just a part of the problems faced by modern society and business. That is why effective protection against cyber attacks comes to the fore. 

A comprehensive analysis of the cybersecurity situation is required. 

There is no one-size-fits-all cybersecurity solution. The very first and necessary step to improve efficiency is a preliminary analysis of the situation. Employees of the company (or an outsourced cybersecurity company) must understand the severity of the problem, weigh all the possible consequences and pay attention to modern data protection methods that have not been implemented before. On the Internet, there are enough articles and expert recommendations on the need to protect data, on the choice of strong passwords and protection of networks for transmitting the information. But few people attach importance to these recommendations until the moment when they themselves become a victim of cybercrime. and will not face scammers extorting money to resume the site. What tasks should be prioritized: 

- regular analysis of the system for the presence of vulnerabilities in it ( penetration test, diagnostics and audit ); 

- constant introduction of new forms and methods of cybersecurity protection; 

- prevention and elimination of the consequences of attacks (cyber attacks).

Technology is at the heart of effective defences against cyber attacks by cybercriminals. And cybersecurity is precisely the struggle of technologies when both sides apply new technologies both for hacking and for protection. After a detailed analysis of the situation, IT specialists in information security offer solutions. Most often, networks in the cloud, routers and PCs (or laptops) need protection. One of the options for the initial way to protect your PC is antivirus software. 

A list of common cybersecurity threats. 

One of the foundations of effective protection against digital threats is understanding the possible risk factors. And the business owner often does not understand and underestimate these threats, so it is recommended to contact cybersecurity specialists. One of the most widespread and frequently encountered threats is so-called phishing. We are talking about receiving a malicious letter that contains software (software, code, script) to steal personal or payment data. It is not always easy to recognize a malicious email the first time. And not every employee of the company is able to understand that this letter is a phishing one. The next possible threat is all kinds of ransomware viruses. As soon as the owner's computers or websites become infected, the cybercriminal requires money in exchange for solving the problem of blocking the PC or website. What can happen during and after a cyberattack : 

- software is installed on the working PC, which gives hackers access to information on the victim's PC; 

- social component - the fraudster uses various methods of deception so that the employee discloses personal information, which is then immediately used to gain access to the corporate information of the company 

- organization of a DDoS attack on the site. One of the most common ways to harm a company by paralyzing its work is through the inaccessibility of the Internet site. 

Is it possible and how to neutralize a DDoS attack at an early stage 

Many requests in a short period of time, which are simultaneously sent to a single site, make it inaccessible - this is a classic DDoS attack. The server is simply physically unable to respond so quickly. DDOS attacks are often used in the fight against competitors, for example, to block access to company resources. 

 Regardless of the reason for the attack, the following may be at risk (at risk from cyberattacks ): 

- financial institutions; 

- large companies of all forms of ownership, which have information databases 

- informational resources 

- payment systems and their partners, on the websites of which online payment services are installed 

- servers and databases of various companies (both large and small businesses)

 A qualified programmer ( IT specialist in the field of cybersecurity ) quickly recognizes the problem and will fix it. Of course, he can be on the staff, but it is quite expensive - to maintain a cybersecurity officer and pay monthly salaries. It is much more efficient and profitable to work with a remote employee of a company that provides cybersecurity services. It is best, though, to invest in prevention rather than "treatment." And prepare all information systems to protect against hackers.  

Analysis of existing types of attacks and preparation of protection against them will help protect the system from attacks by cybercriminals. The most dangerous situation is when the infrastructure itself is under attack. In this case, the criminal's goal is to destroy or seize hardware resources.  

Effective ways to protect your site from hacking and DDoS attacks. 

A vulnerability discovered in time will never become a threat to be exploited by criminals. Therefore, threats must be looked for while everything is still and calmly. There are several ways to protect your site from hacking. If the task of anti-virus protection is to detect and eliminate (if possible) threats, then checking for regular software updates and controlling access to data forms protection in advance, before threats are detected. When working with cybersecurity, there are no trifles, every little thing is important here, every PC in the company and every employee with access to data. What can be recommended at the initial stage of the formation of cybersecurity in a company: - restricting access to the administrative panel; - regular scanning of the system for vulnerabilities; - use of application firewall and CDN; operational blocking of traffic at the slightest suspicion of a cyber attack.

 Recovering lost data after DDoS and other types of attacks   

If it suddenly happened that the problem could not be avoided, you must immediately start recovering the lost data and information. Every minute decreases the chance to restore the data to its previous state. One of the easiest and most affordable ways to solve the problem is to use a backup copy of the data, which must be regularly updated and updated. This minimizes the time and effort required for further recovery.  Backups can be created either by the user independently in manual mode or by the hosting itself or by a cybersecurity outsourcing company. It is much more difficult to resume the work of information systems if the backup was not carried out or was carried out irregularly. To solve this problem with the least loss will help to seek professional help from the IT security specialists of the Datami company.
