What Is Cloud Computing Security Services?
All the signs point to cloud computing as the way of the future. Not only are increasing numbers of companies starting out as cloud-native, but even companies that have already invested heavily in traditional infrastructure and products (such as standalone software) either have moved or are moving over to the cloud. Scroll down the page to know cloud computing security.
Cloud infrastructure offers many benefits over traditional, on-premises infrastructure
There are all kinds of good reasons for this, including economy, flexibility, and scalability. What’s more, for many companies the cloud can actually offer better security than anything they could have achieved on their own. This is particularly true of SMBs, which often have limited knowledge and resources.
At the same time, moving to the cloud does not eliminate all security challenges, it just changes their nature and as such traditional managed IT security services have had to adapt and become cloud computing security services. Here is a quick guide to some of the key ways in which they support their clients.
Identity and access management
One of the main reasons why even a public cloud can be more secure than on-premises infrastructure is that good digital security starts with good physical security. That’s why reputable cloud vendors generally house their infrastructure in buildings that are designed to prioritize security and why they make sure to invest in state-of-the-art technology and appropriate personnel to ensure that it stays secure.
At the same time, data security is a shared responsibility. It is the cloud vendor’s job to ensure that you are protected from external threats using cloud computing security, be they natural ones (such as fires and floods) or human ones (such as cybercriminals).
It is the organization’s job to make their access in such a way that people are given what they need (and perhaps some or all of what they want, provided that it is relevant to their work) and no more. It is also the organization’s job to ensure that these accesses are only ever used by the person to whom they were given and for legitimate, work-related purposes.
In principle, intrusion management is largely the responsibility of the cloud vendor. In practice, many cloud users do prefer to have their own intrusion management systems in place as a backup. This is particularly likely if using the public cloud where the multi-tenancy system does create more scope for intrusion, even if genuinely unintentional.
Security Information and Event Management
Similar comments apply to Security Information and Event Management. In principle, it is usually your cloud vendor’s responsibility to manage this but in practice, it doesn’t hurt to have a cloud computing security service undertake this task for you, partly as a double-check and partly because it can help to keep auditors happy.
Prevention of data loss
Cloud-based data-loss prevention services tend to work very similarly to their on-site counterparts. Typically, the software will be built into the service offered to that client and will run an agreed set of rules to monitor, protect and verify the data both while it is on the server and while it is being transferred from one location to another.
As with intrusion monitoring, the prevention of data loss is of particular significance in public-cloud environments, where there is more potential for data leakage (even if only accidental) or even theft (via intrusion, hence the importance of all-around security monitoring).
This, again, is very similar to its traditional, on-site, counterpart and is generally used in tandem with robust antimalware protection. At a basic level, web security can set rules about acceptable sites (for example by whitelisting or blacklisting depending on the strictness of your policy) and any period when browsing is or is not permitted (for example limiting it to lunch periods). For more intense security, web traffic can be proxied or redirected to the cloud provider.
This is also very similar to email security in the on-premises environment, but the subtle differences are important. For example, there can be much more emphasis on digital signatures for robust identification (and hence non-repudiation).
It is impossible to overstate the importance of encryption in any environment, including the cloud. Quite simply it has become a prerequisite for effective data security and for compliance with many regulatory programs in cloud computing security.
Last, but definitely by no means least, if you’re using Infrastructure as a Service, then you’ll need to manage network security.

Picking the right cloud-computing security services partner
When it comes to cloud computing security services, the main challenge is not necessarily knowing what you should do. In essence, that’s just following current security best practices. It’s knowing how to do it in a cloud environment, which often means how to integrate everything into one whole while still ensuring that all components work effectively. Often, this means working very closely with your computing security services partner, and hence it can be very helpful to “go local”, for example, if you’re in Sacramento, CA, then give priority to cloud-computing security services in Sacramento, CA.
