What do you need to consider when choosing an email service provider? First of all,
their privacy policy, that is: what data they collect and store about you and for how long, as well as with whom else they share this data and under what conditions.

What are DDoS attacks and why is it harder to defend from year to year
According to the NETSCOUT Threat Intelligence active threat level analysis system, the largest number of attacks that our partners have ever seen occurred during the pandemic — 4.83 million DDoS attacks in the first half of 2020 (15% more than in 2019). And the frequency of DDoS attacks increased by 25% in the period from March to June.

However, it is worth noting that the number of single-vector attacks in the first half of 2020 decreased by 43% compared to the same period of the previous year. And the number of complex multi-vector (15+ vectors) attacks have increased by 126% over the past year and by 2851% since 2017.

methods of combating DoS/DDoS attacks
Your morning starts with reading bug reports and analyzing logs. You update the software daily
and update the firewall rules hourly. Snort is your best
friend, and Zabbix is your invisible assistant. You have built a real bastion, which
cannot be approached from any side. But! You are completely defenseless against the most
insidious and vile attack in the world - DDoS.

Distributed Network Attacks / DDoS
Distributed network attacks are often referred to as Distributed Denial of Service (DDoS) attacks. This type of attack uses certain bandwidth limitations that are characteristic of any network resources, for example, the infrastructure that provides conditions for the operation of the company's website. A DDoS attack sends a large number of requests to the attacked web resource in order to exceed the site's ability to process them all... and cause a denial of service.

How to protect yourself from DDoS attacks?
How to protect yourself from DDoS attacks, what steps to take? First of all, it is not necessary to postpone it "for later". Some measures should be taken into account when configuring the network, starting servers and deploying software. And each subsequent change should not increase vulnerability from DDoS attacks.

DDoS attacks: Attack and defense
News headlines today are full of reports of DDoS attacks (Distributed Denial of Service). Distributed denial of service attacks are subject to any organizations present on the Internet. The question is not whether you will be attacked or not, but when it will happen. Government agencies, media and e-commerce websites, websites of companies, commercial and non-profit organizations are all potential targets of DDoS attacks.

DoS attack
A hacker attack on a computer system in order to bring it to failure, that is, the creation of such conditions under which bona fide users of the system will not be able to access the system resources provided, or this access will be difficult. The failure of the "enemy" system can also be a step towards mastering the system. But more often it is a measure of economic pressure: the loss of a simple service that generates income, bills from the provider and measures to avoid an attack significantly hit the pocket of the "target". Currently, DoS and DDoS attacks are the most popular, as they allow you to bring almost any poorly written system to failure without leaving legally significant evidence.

What is a keylogger?
A keylogger is a program that registers user actions on a computer and logs the following dаta: the time of the session on the computer, the time of launching and closing individual programs, which documents and when were opened, the addresses of visited websites, which files were downloaded from the Internet, all keys pressed (i.e. all passwords, codes and logins).

Invisible Internet Project I2P (Invisible Internet Project)

The I2P network (Invisible Internet Project) is an "overlay" network, i.e. an independent network that does not intersect with the Internet in any way and operates according to its own laws. This is the so-called network over network. Inside I2P, all transmitted traffic is securely encrypted and if someone intercepts it, it will be very, very difficult for him to decrypt anything. In addition, IP addresses are not used in the I2P network, so it is almost impossible to determine your IP address and establish personal data. Let's look a little more into what I2P is.

Threats from the Internet or "Who needs me and my computer?"

A lot of people neglect the basic rules of network security, because they think that it is absolutely not important. Many years ago there was a time when I thought: "Yes, who needs me and my computer?" and also ignored the rules of Internet security.

How and why to protect your home Wi-Fi network?
Currently, home wireless Wi-Fi networks are very popular. They are created even if there is only one computer in the apartment, as it is very convenient when the wireless router is in the corridor, and you can connect to the Internet from any device anywhere in the apartment. As a rule, modern wireless routers do not even require any configuration, or it is minimal.

Deleting files from a computer without the possibility of recovery
When you delete a file, even after deleting it from the trash, it doesn't actually disappear from the hard drive. It's just that all data about it is erased from the system table, which contains information about files that are located on the hard disk. Therefore, it will not be difficult for a specialist to restore a deleted file. In addition, this "deleted" file can be stored on your hard drive for months,

How to securely encrypt the contents of your computer?
If you have confidential documents that you would like to securely protect so that no one can open them except you, then there are several ways to do this. For example, set a password for an MS Word file or archive. Yes, it is not difficult to set a password for an MS Word file or archive, but this method is the most unreliable, since it will protect only from amateurs. There is another very reliable way to protect data – it is their encryption.

How to protect your social network page or email account from hacking?

What can I say if the smartest programmer in the world, the owner facebook.com Mark Zuckerberg had the password “dadada" for his Twitter and Pinterest accounts until it was made public by a group of hackers.
