security

In the meantime, they are quite capable of fixing selectively. The author can not say they do so or not, but knows exactly what is possible in principle to itself – have. Someone may say that, to example, the GSM standard, all negotiations on the radio – is encrypted. Serious and powerful. How to fix? My answer: encryption exists only on the radio at the same switch, all data are processed in unencrypted form and do not need any additional equipment, besides the standard interface to SORM to get full access to information. Further, everything happens for a standard scheme.

The same thing – and with Internet traffic: it can be encrypted on subscriber line service provider, but the provider works with unencrypted traffic. More info: Technology Investor. The exception applies only to tunnel junctions, when the public access network used to transmit traffic encrypted sender and that can only decode the recipient! So, the FSB officers have access to resources quite all communications providers and can quite arbitrarily listen to any calls, and analyze traffic any subscriber. But that's not all. Also, they can carry out the substitution rates. But they are not alone. Peter Thiel contains valuable tech resources.

For example, the long evenings on the switch, the author invented a fun one: he cheated on most PBX her phone number and For example, when he phoned her friend, she determines the number of her beloved mother, and not the number of the author. This was done just by pressing a couple buttons on the keyboard. Exactly the same things can make employees KGB: the author made repeated calls to discharge the same way that it was determined the same author's own room! To demonstrate the possibilities, the staff has also been shown to have full access to all resources Stations provaydrov all, to the point that they can just temporarily disable multiple base stations with absolutely no knowledge of the provider. So if your cell phone lost network in the city center, it is quite possible, it is not technical issues, and information blockade during special opertsii. As you can see, the KGB about the opportunities that exist in the FSB, could only dream of, and hence the phrase: let's meet – it's not a phone conversation, not lose its relevance, rather the opposite – Big Brother is gaining momentum.

Make backup copies needed. Everyone knows that. But in practice it is running low. Need a capacious backup server, a program for creating backups and the ability to manage it all. I propose to consider a decision on the basis of cheap NAS-drive D-Link DNS-323 and free software. I understand that many system administrators smile: to put a little box NAS-drive instead of a full server? But do not rush to conclusions.

Described solution fully satisfy the organization to fifty computers. The general principle is as follows: – All computers are connected to the network – a network drive D-Link DNS-323 is also connected to the network – a network drive create a folder called BACKUP for copies, and a folder for USERS The other files – each computer backs up and dumps it on the NAS-device in the folder BACKUP; – BACKUP folder is accessible only to the network administrator, users do not see this folder, here we will not describe the installation process Network Storage D-Link DNS-323. Box hard drive, the formatting, setting up – all this is quite detailed in the instructions, as well as posted on the Internet. We mention only some important points. Firstly, in our device used firmware (firmware) version 1.03, which we shall consider. Second, hard drive assigned labels 'Volume_1' and 'Volume_2'. Third, the device named 'DNS-323' and the IP-address 62.76.0.2. All these parameters can be viewed on the tab 'STATUS' and change tab 'SETUP'. Thus, all the equipment in the network, start Setup Enter the page controls D-Link DNS-323.

Analysis of the system is logical that in order to detect and neutralize malicious program requires the existence of such program. Prevention is prevention, let’s talk about it later, but it must be the first thing to determine is whether the computer viruses in general. For each type of malware, respectively, have their own symptoms, which sometimes visible to the naked eye, sometimes subtle at all. Let’s see what all are symptoms of infection. Since we are talking about a computer connected to the global network, the first symptom is excessive rapid rate, as a rule, outbound traffic is caused by the fact that many Internet worms serve ddos-machines or simply bots. As is known, ddos attack, the quantity of outgoing traffic is equal to the maximum magnitude of traffic per unit time. Of course, the Gigabit it may not be so noticeable if done ddos attack the width of a dialup connection, but usually catches the eye of inhibition at the opening of the Internet resources (I would also like to note that it will focus on viruses that are at least as something to hide yourself system, it is no need to explain anything if you have a Startup folder is a file kfgsklgf.exe who caught a firewall, etc.).

next to list, it is impossible to go to many sites of antivirus companies, failures in the paid programs like crc-error, this is due to the fact that quite many commercial protectors support the function of parity or the integrity of the executable file (and not only protectors, but the developers of protection), that has been done to protect the program against hacking. Let’s not talk about the effectiveness of this method against crackers and reverser, but the alarm to viral infection that might work idealno.Esli you still have picked up the virus, then you have to resort to service removes viruses on your computer. Fee for beginners virmeykerov not kill processes, then that shutdown or restart the computer goes a long completion of a process, or even the computer hangs during shutdown. Think about the processes of speaking is not necessary, as well as about the Startup folder, if there is something strange or new, then perhaps it is a virus, but about that later. Frequent rebooting the computer from the Internet boom, the completion of anti-virus software, server unavailability updates microsoft, inaccessibility sites of antivirus companies, errors when updating anti-virus, bugs caused by changes in the structure of fee-based programs, message windows, that executable files are damaged, the appearance of unknown files in the root directory, it is a short list of symptoms of an infected machine. In addition to direct malware exists a so-called spy software, it’s all kinds of keyloggers, dumper electronic keys, junk ‘Helpers’ to the browser. Frankly, the method of detection can be divided into two opposing camps. Assume keylogger adjoint dynamic library to the shell of the operating system found on the fly extremely difficult, and vice versa, nowhere grafted Assistant (plugin, the search string, etc.) to the internet explorer’u (usually) catches the eye immediately.
