Organizations discover themselves in a quandary lately on the subject of whether or not they need to deploy an air-gap technique—a method by which secondary backup knowledge is saved in an offsite and offline location, bodily separating it from main manufacturing knowledge—to higher defend their secondary knowledge.
On the one hand, the rising menace posed by cyberattacks makes it essential for organizations to have an air-gapped copy of their knowledge that they’ll use to recuperate any main knowledge that has been encrypted or deleted by a cyberattack. However, offsite tape storage, the standard expertise used for creating an air-gapped backup, is pricey, has gradual restoration instances and scales poorly, making it troublesome for organizations to implement an air-gap technique in right now’s digital economic system. Relatively than utilizing off-site tape storage, some massive organizations preserve or pay for hosted knowledge facilities to air-gap their backups. However whereas this strategy offers sooner restoration instances than tape, it’s rather more costly when it comes to each direct bills and administration prices.
Thankfully, new software-as-a-service (SaaS)-based backup and restoration options supply a manner for organizations to create a “digital” air hole between their main and secondary knowledge, with out the associated fee, time, scalability and different points related to tape storage. By deploying a strong SaaS backup and restoration resolution that features encryption of knowledge whereas it’s in transit and at relaxation, anomaly detection and different enterprise-grade knowledge safety capabilities, organizations can understand the advantages of building an air hole between their main and secondary knowledge whereas growing their restoration speeds, enhancing their backup scalability and decreasing their backup prices.
The Want for Air-Gapped Backup
The specter of a ransomware or different cyberattack from malicious hackers or nation-states has been one of many key the explanation why organizations have created air-gapped backup copies of their knowledge for years—and this menace solely continues to develop. In February, the New York Occasions reported that ransomware assaults in 2019 elevated by 41% from the yr prior. In the meantime, in April, the European Union Company for Legislation Enforcement Cooperation (Europol), issued a report that acknowledged that, following the pandemic, “some [cybercriminals] are believed to have intensified their actions.”
As organizations discover that they’re more and more confronted not with the query of if a profitable cyberattack will lock or destroy a few of their main knowledge however when, the necessity to implement an air-gap technique has turn out to be extra pressing. The truth is, the Cybersecurity and Infrastructure Safety Company (CISA), a part of the U.S. Division of Homeland Safety, emphasised the significance of making air-gapped backups, advising: “Be certain your backups are saved in a location that’s simply reached when wanted, however which is air-gapped from the manufacturing community.”
The Limitations of Air-Gapped Tape Backup
But, whereas the necessity for air-gapped backup is larger than ever, offsite tape backup is more and more too cheap, too gradual and never scalable sufficient for organizations attempting to reach right now’s digital economic system.
These organizations’ knowledge volumes are rising, typically at an exponential charge. However tape storage is troublesome to scale and might be costly, particularly as knowledge volumes develop over time. In the meantime, organizations want to have the ability to rapidly recuperate their knowledge after an assault in the event that they don’t need their more and more digital operations to be considerably disrupted. But, organizations can’t immediately retrieve a tape backup from an offsite location; they’ve to attend for it to be delivered to them. As well as, with tape the precise knowledge restoration course of can take a very long time as it may be troublesome to seek out the precise knowledge that has been locked or destroyed or knowledge that’s extra important to the group and must be restored as quickly as attainable.
SaaS: An Various for Air-Gapped Backup and Restoration
With the introduction of latest SaaS backup and restoration options, organizations now have a quick, inexpensive, and scalable different to tape storage that also allows them to create an air hole between their main and secondary knowledge.
A SaaS backup’s air hole is digital, not bodily, for the reason that cloud the place the backups are saved isn’t bodily disconnected from the web when a backup or restoration course of isn’t in progress. Nonetheless, this digital air hole could be very near being as safe as a bodily air hole. All entry to the backup needs to be made by a certified person, and when backup or restoration processes are usually not occurring, the communication between the first and secondary knowledge is severed, in order that the secondary backup knowledge is totally separated from the shopper’s on-premises safety area. As well as, the truth that the SaaS backup is saved on a special kind of media (the cloud) and makes use of a very completely different set of APIs than on-premises storage additional complicates cybercriminals’ skill to entry it.
Furthermore, SaaS backup and restoration is quite a bit sooner, inexpensive and extra scalable than air-gapped tape backup. When a company must recuperate knowledge, it may immediately connect with the cloud, discover the precise knowledge it must recuperate and restore it—there isn’t any want to attend for a tape to be delivered from a distant vault someplace, after which attempt to discover the info on the tape that they wish to recuperate first. SaaS storage within the cloud can be inexpensive than paying an organization to retailer tape in a safe offsite location, includes much less administration overhead (additional reducing TCO) and is far simpler to scale up or down as a company’s knowledge safety adjustments.
In selecting a SaaS backup and restoration resolution, organizations can achieve additional advantages from deciding on an answer that features enterprise-grade knowledge safety capabilities. These embrace anomaly detection that may establish behaviors that point out a malicious actor has attacked the first knowledge and is now attempting to assault the backup. Different capabilities to search for in a SaaS backup and restoration resolution embrace knowledge encryption whereas knowledge is in transit and at relaxation, two-factor authorization and ISO certification for the cloud knowledge facilities the place the SaaS backups are saved.
Because of its skill to create a digital air hole between main and secondary knowledge, SaaS backup and restoration options supply organizations a strategy to implement an air-gap technique that helps them higher defend their backups from cyberattacks whereas nonetheless offering them with the short, inexpensive and scalable backup and restoration they want in right now’s digital economic system. With SaaS backup and restoration, organizations now have one other highly effective weapon of their arsenal as they search to guard their knowledge from cyberattacks.
