Air gapped backups reside outside main networks, often in separate buildings, sometimes in what’s called a Faraday Cage (an enclosure that neutralizes electromagnetic waves). A standard protection strategy dictates that employers should transfer data between source and target by themselves on removable devices such as USB sticks. This air-gapping technique is the most stringent security measure and a robust defense against data loss.

The scheme was later amended to address cybersecurity challenges like ransomware better. The corrected version adds two digits to the codename and reads 3-2-1-1-0. “0” refers to the fact that all copies must be free of errors. “1” means that one of the three copies must be immutable or air-gapped.

Perpetrators of ransomware are trying to keep up with the defenses deployed against them. Most recently, they set their crosshairs on backups, rightly convinced that if they scramble them, the victim will have no recourse but to surrender.

Some cloud vendors offer air gapped backups. While ostensibly a contradiction in terms, cloud air gap backups provide similar security as local implementations do. They leverage logical processes to keep data safe and are only used to restore and ingest information. Disconnected in the interim, they’re effectively off-site repositories with occasional network connectivity.

Some companies prefer logical air gaps instead. These follow the same security principles as physical air gaps but apply them through software. The software isolates the volume from the network, even as the volume may remain physically attached to it. The mechanisms responsible for the separation include encryption, firewalls, or access control management—for example, S3 Object Lock.

Physical air gaps often leave little to no paper trail. This increases the risk of someone from within the company stealing data because they can do it with relative impunity. Make sure your team is trustworthy and reliable.

With their time-saving convenience, safety features, and energy efficiency, snow melt systems can make your life easier while also helping keep your family safe from slips and falls caused by icy surfaces around your home. All in all, they’re an excellent option for those looking for an easy way to keep their property free of ice during cold weather months! Make sure you have a new snow melt system installed before next winter comes – call Atomatic Mechanical Services, Inc. today for a quote!

Air gapping is a method of protecting data by physically separating a storage volume from all possible access points, wired and wireless. After the isolation, the volume becomes a country within a country, even within its own infrastructure, removed from internal workloads and processes. If hackers breach the network, air-gapped data remains inaccessible – hidden behind a barrier known as an air wall. This air wall adds another layer of protection and prevents unlawful manipulation except through direct manual tampering or destruction. Because of these attributes, air gaps are considered one of the best backup practices.

Companies who want to set up an on-prem air gapped backup can choose from the following three options. Each adheres to rigorous security standards while balancing security and convenience differently.

While winter is almost over, it’ll be here again before we know it – you need to be thinking about how you want to keep your home and walkway safe and snow-free next winter. Snow melt systems are a great solution for those in the cold Chicagoland area. They provide a fast, efficient, and cost-effective way to melt the snow around your home while also keeping you safe from slippery surfaces. Atomatic Mechanical Services explores the benefits of snow melting systems, as well as how they work so you can see for yourself!

Ransomware is a malicious program that sneaks inside a network, encrypts its data, and leaves a conspicuous ransom note demanding payment in exchange for decryption.

An air gapped backup is an offline copy of data fortified by an air wall. Air gapping suits virtually nothing better than backups because it makes them impenetrable and inaccessible. Conversely, operations would likely halt if one were to air gap a production environment because of the inherent transfer delays. For this reason, the air gap technique lends itself great to backups.

Both snow melting systems have a self-regulated temperature sensor. This process creates warm surfaces that can quickly melt snow and ice from even the harshest winter weather conditions.

A physical air gap involves a literal space—a buffer—between the backup and production. Consider these factors before implementing such a buffer:

Updating air gapped backups takes time and effort. Unfortunately, there’s no easy workaround. Expect a backup procedure to last a few hours instead of minutes or seconds, as it would with the cloud. When considering air gapping, decide which matters more – security or speed. Air gapped backups tip the scales toward the former.

An air gap insulates sensitive data and keeps bad actors at bay, strengthening a ransomware defense strategy – provided that other security measures complement it.

American photographer Peter Krogh proposed a 3-2-1 rule. Krogh believed every backup must consist of three identical copies. Additionally, these copies should use at least two different mediums—for example, tape and HDD—with one located offsite in case of an on-site disaster.

Some organizations, however, can’t or won’t use air gaps this way. Maintaining an extra facility for physical devices, walking from one place to another, and investing in a Faraday Cage might be too cumbersome and inefficient. But that’s not the only air gap strategy out there.

But there are some caveats. For example, many organizations struggle to map their network connections faithfully. This confuses connected devices. Specifically, assets believed offline may turn out to be online when audited. Make sure you know the structure of your network through and through.

Air gaps shield sensitive information and critical data better than other protective measures. Still, it’s essential to take to heart the words of Gene Spafford, who said: “The only truly secure system is one that is powered off, cast in a block of concrete and sealed in a lead-lined room with armed guards – and even then I have my doubts.“

Snow melting systems work by generally consist of two parts—a heating element and a sensor. The sensor detects when temperatures drop below freezing, or significant snow melting temperature, it activates the heating element accordingly. When temperatures rise back above freezing, the system shuts off automatically until temperatures drop once again. This makes them incredibly efficient in terms of energy use since they only cycle between on/off states as needed rather than running continuously all winter long. Snowmelt systems are typically installed directly beneath concrete slabs or asphalt surfaces for maximum efficiency.

Snow melting systems can be installed on under asphalt for parking lots and driveways, or under concrete for sidewalks and walkways. Many business owners invest in snow-melting systems for metal entryways to their businesses to prevent slips and falls. If you have an elderly relative or someone in your family that uses a wheelchair, having a heating system remove snow and ice from a ramp can make moving them around much easier during the winter. Many Chicago area buildings with flat roofs also use snow-melting systems to prevent snow from accumulating on their buildings.

Finally, logical air gaps trade off security for speed and convenience. Strictly speaking, they are always connected to the network and rely on software for sequestration. A physical air gap might be the better choice for bulletproof security.

Air gapping does not eliminate data transfer. Intermittent connectivity opens offsite copies to physical access and exposes them to vulnerabilities. Leverage immutability, encryption, and sophisticated role-based access to fortify them against that.

Air gapped backups provide excellent security against cyber attacks, but they come at a price. To find out if they have their place in your organization’s security strategy, consider the following questions.

A hydronic snowmelt system is an efficient way to clear away dangerous ice and snow accumulations. These can be electric systems or hydronic systems depending on the type of material it needs to heat and the climate it works in. An electric snowmelt system uses an electric current by heating cable or panels to generate heat to melt snow on the surface above. A hydronic system works by circulating heated liquids such as water or glycol through a piping installation, usually located beneath the surface of driveways, walkways, or streets.

Air gapping does for software what social distancing does for people—wards off infections. It’s a backup and recovery strategy that stops malicious agents from infiltrating, buttresses the security posture in hyper-converged infrastructure (HCI), and plays a crucial role in recovery procedures such as disaster recovery plans (DR).

One backup does not cut it when data is a matter of life and death. But how many backups are enough to prevent data loss?
