Is A cloud safer than on-premises servers?
Due to security concerns, businesses have been hesitant to shift apps and data to the cloud in the past. Executives are most concerned about their conversations being exposed. When I asked these same executives where they save their confidential emails, texts, and direct conversations, virtually all of them said: “in the cloud.”
Transferring your data to reliable cloud hosting providers like Amazon Web Services or Microsoft Azure delivers a degree of protection that can’t be matched on-premises.
This is because most businesses lack the financial and human resources to provide the same level of security as major cloud service providers.
1. High availability matters more than ever
When you go to the cloud, your data is kept in numerous geo-independent data centres, with redundancy built into the system. Your data isn’t just duplicated to one data centre; it’s scattered among several, so if one goes down, your data will immediately failover to another.
Virtualization is also used by large cloud providers to ensure availability. When servers are virtualized in the cloud, providers may quickly move them from one data centre to another in the event of a disaster. Most on-premises systems are made up of simply two physical servers that failover to each other. If there’s a fire or a major network outage, this isn’t very useful.
2. Physical security is costly.
Preventing physical theft takes a lot of work and money. Heavy security, such as guards, mantraps, and secured cages for the servers, is required to completely protect your on-premises servers.
Your labour and money for all of that vanish when you move to the cloud. Cloud companies invest in round-the-clock security and cutting-edge physical security procedures. Targeted physical theft is nearly impossible due to the scale and security of these data centres.
3. Improve your technological safety.
Patching is one of the most difficult security concerns that businesses of all sizes face until they go to the cloud. Several of the most serious security breaches, such as Equifax and the WannaCry epidemic, were caused by a lack of patching.
The large cloud service providers, like Microsoft, Amazon, and Google, could recruit full-time staff devoted to updating their products, unlike most businesses. Patching on the cloud is usually automatic, which reduces the downtime that patching on-premises necessitates.
4. 24/7 requires heavy staffing
To fully monitor data centre security, you’ll need to recruit people that are available 24 hours a day, seven days a week to keep an eye out for threats. Most businesses just cannot afford it. Cloud providers have full-time employees and a security operations centre (SOC) that monitors their entire infrastructure around the clock.
5. Network segmentation is advantageous to the cause.
Segmentation from user workstations is a big security benefit the cloud provides over on-premises servers and infrastructure. Phishing and email-borne attacks are the most popular ways for attackers to gain access to networks. Attacks are usually always launched from user workstations. They seldom originate from the server environment directly. All of your workstations are totally separated when you’re hosted in the cloud. Users in the cloud aren’t connected to the corporate network, where the data is stored.
6. Encryption is made easier.
Companies may find it difficult to establish encryption throughout their whole environment, whereas cloud providers often provide encryption out of the box. Because the largest cloud providers utilize military-grade AES 256 encryption, attackers won’t be able to read any data they could take. Encryption helps avoid data disclosure.
7. The most significant dangers of keeping data in the cloud
There are undoubtedly advantages to cloud data storage, but there are also drawbacks to be aware of. The following are some of them.
Privacy: Privacy is the most significant concern while using the cloud. When you commit your data to a cloud service, the company has access to your data, can view your files, and read your emails. Regarding government subpoenas, this is extremely troublesome. Cloud service providers aren’t in the business of defending you against the government.
Misconfiguration: Breach and exposed data are frequently the result of improper cloud storage settings, albeit this is not always a cloud-created danger. This commonly happens when the person in charge of storage unlocks rights to help a user, and the data is subsequently accessible to the entire world.
When relocating, there are a few things to keep in mind.
Although the cloud is quite safe, businesses must exercise caution to develop and maintain a secure environment for their critical data.
Here are the best ways to protect your cloud server data ahead of time:
Multifactor authentication should be enabled.
Your own encryption keys are required.
An IP address is used to restrict access (i.e., office or VPN)
Select a reliable and audited cloud service provider.
Your cloud suppliers can assist you in being watchful if you accomplish all of this and remember your shared responsibility security approach.
