The collapse in the network can happen even because of air conditioning — the editor of the Next Web about the fragility of services

Cloud computing systems created by the mankind, maintain the efficiency of most services, which it is, writes The Next Web. It and e-mail clients, and online stores, and sites for sharing photos. “Health care, social services, even some of the government mechanisms start to work over the Internet”. “The users and developers of such systems should be more careful — experience shows that we are becoming more and more dependent on them.

The failure of one service may lead to denial of others as they are all interconnected. Sort of a patchwork quilt,” says the newspaper. The author cites as an example the recent prolonged failure of Skype, as well as temporary malfunctions in Facebook. “If the social network Facebook completely did not work, so users of the site, which provides the authorization via Facebook account, can they go”.

Losing access to Facebook will cause only irritation, while problems in major health or social services, or in the various power management systems can be applied to the economy and even the lives of the people irreparable damage. At the end of August 2015 in data center in Belgium Google has got four lightning strikes in a row. As a result, the company lost about 0,000001% of the data — that is, about a few gigabytes of user information.

“Lesson. Do not trust the cloud providers and back up your data. As for backups, you should create a separate backup copy,” writes The Next Web.

Former U.S. Secretary of defense William Cohen in the summer of 2015 made a statement that the countrys energy industry is actually much more vulnerable than many residents can imagine. “Terrorist attack on the power system can cause chaos throughout the country — from one coast to the other. And this is a real prospect”, — he told. Janet Napolitano, former Secretary of the Department of homeland security U.S. does and believes that with regard to cyber attacks on the power system can not be used the particle “if” — the question really is only “when”.

“As a former electrical engineer, I understand how important the security of some systems from accidental failures, the author writes material. — Multiple power sources — it is not uncommon for critical equipment. It is important to understand that the crash happens sooner or later. Backup for your backups” — he calls.

A good example of the vulnerability of networks — a massive power outage in 2003 that deprived electricity to 45 million people in the United States. The incident occurred due to the fact that at one station in Ohio fails software worked but after the so-called “Domino effect”. According to the author of the material, the operability of the system was restored two days.

The weakest links in almost any system, the author writes, is the least obvious elements of infrastructure are most open to attack. For example, a failure in the air conditioning system in the data center can lead to various problems and even melting equipment. “Such cases can undermine any system of banking operations, management of road traffic, technical support of a large company”. The more dependent we become on data and the processes of their treatment, the more we are vulnerable to their loss.

Critical systems use fault-tolerant mechanisms, but these mechanisms can be attacked. “The cloud” is not as resilient as we think. By itself, the world wide web, says the author, is not so divided as it seems any user — crashing and on any of its key physical points can lead to very serious consequences. For example, root DNS servers that provide connectivity and network uptime, the worlds only 13 — and they are one of the weak points of the Internet.

“We still rely too much on the physical hardware. Attack on any of these points can lead to collapse,” concludes the author.
