One of the biggest concerns for businesses is the security of the data that more and more of us are entrusting to cloud storage systems. Unfortunately, many people assume that the cloud service provider is responsible for keeping their data safe, but this isn’t accurate. In fact, the cloud provider is responsible for keeping the cloud itself safe, whereas the customer remains responsible for the data stored within it. In many cases, the customer does not have full visibility of the cloud which can leave them vulnerable to data breaches. This guide introduces some of the most common cloud security issues as well as tips to help you. combat them within your organization.
Lack of visibility and control
Cloud storage systems are managed by a third party, which can restrict how much visibility the customer has of the data. Without complete visibility of all the data being stored in the cloud, it is much more difficult to keep all of that data secure. To improve how much clarity and control you have of your data, consider taking advantage of a professional security product such as McAfee Cloud Security Services. This will integrate with McAfee device security to provide visibility and control over data and threats across a private cloud, SaaS, PaaS or IaaS.
Inadequate access management
The cloud is often a prime target for cybercriminals because once they have gained access, they typically have all of the important data at their fingertips as it acts as a central storage area. If you are using weak user authentication processes and/or passwords, you are making their task even easier. To increase the level of protection around your cloud, you should be creating strong passwords (and changing them on a regular basis) as well as using multi-factor authentication processes.
Phishing attacks often come via email and involve a hacker sending what appears to be a legitimate email. In that email will be an innocent-looking link and a compelling reason to click that link, but if you do click, the hacker can then hijack accounts, interfere with data, spy on transactions, and redirect users to fake websites designed to capture personal information. In addition to a strong passwords procedure and multi-factor authentication, it’s also important to train your staff on how to recognize a potential phishing attack.
Human error or natural disaster
Sometimes data can be lost from the cloud through a simple case of human error or due to a natural disaster such as an earthquake or a fire. It’s not always possible to anticipate or prevent these incidents, which is why you need to ensure that the data in your cloud is being backed up on a regular basis. When choosing a cloud service provider, be sure to clarify what their disaster or human error recovery plan is.
Malicious intent from insiders
Unfortunately, sometimes data breaches happen because somebody who either used to work for you or still does maliciously causes data loss through deletion, theft or manipulation. Major data breaches have occurred in the past because employees have wanted to cause issues for their employer or they have been sympathetic to the hacker’s plan and stood to benefit from it. To combat this, limit user access to the areas of the cloud that they need to do their job to prevent them from having access to highly sensitive information. This is also another reason for strong authentication and password procedures as well as regular employee monitoring.
