There are a number of key data security issues to be aware of in cloud computing. Find out more about what they are and how to protect your data in the cloud.
Online activity is rapidly increasing, leading to more data being stored in the cloud rather than on hardware. Cloud services come in three types: public, private, and hybrid. The public cloud, the most common, has third-party providers owning and operating resources like servers and storage. The private cloud is managed by a single organization but may be hosted by third parties. The hybrid cloud combines both, allowing data to move between public and private clouds. Organizations can host sensitive information privately while storing other services in public clouds.
Data security in cloud computing, such as antivirus for cloud systems, works to protect digital information from any threats that could jeopardize its integrity. Online data often contains private information like addresses, payment details, and medical records, making it a target for cybercriminals. Security measures are needed to prevent data leaks and protect individuals’ private information.
Data in transit, actively moving between locations, needs protection. As data travels between networks—cellular, WiFi, or others—it often becomes less secure and can fall outside of a firewall, increasing risks to cloud security and privacy. While finding a security function to protect your information, you should ensure it also covers data when in transit. Many safeguarding features opt to encrypt data within the cloud infrastructure when on the move to protect it.
What are the security issues in cloud computing?
Cloud computing has several security issues that can put data at risk. For example, data in transit is vulnerable when it moves between locations and is no longer protected by a firewall. The cloud’s design for multiple users increases its risk, as more users mean more access points and potential vulnerabilities. With more people – and more devices – having access to the cloud, the danger of cyber criminals entering the infrastructure increases.
Data breaches
Compromised cloud data safety can lead to attacks, such as data leaks. If a cloud service or connected device is breached, it exposes sensitive data. If a cybercriminal has access to this information, they could choose to distribute it. When the data in storage is transferred, either electronically or physically, it becomes leaked. As the cloud does not use hardware, cybercriminals can leak cloud data online or by remembering information and distributing it later. Also known as low and slow data theft, data leakage is a common danger in cloud computing.
Personal health information (PHI), personally identifiable information (PII), trade secrets, and intellectual property are often the targets of data breaches and require some of the highest levels of security in cloud computing.
Data loss
Another common cloud storage security risk is data loss. As opposed to information being stolen and distributed, it is erased entirely. This could either be the result of hacking, a virus or a system failure – this poses an issue when data is not backed up, highlighting the importance of securing cloud services. However, if a cyber criminal is targeting specific data, they may target the backup as well.
Data loss can be damaging for a business. The information can be difficult or impossible to recover. You may also find recovery attempts use a lot of time, money, and resources. Some data may have to be recreated while others may be found in hard copy formats that need converting. Data loss can be very disruptive to workflow.
Cryptojacking
Cryptojacking is a form of threat that uses resources to mine cryptocurrencies. The threat can control cloud networks to hack web browsers and compromise endpoints. Security weaknesses can expose cloud infrastructure, making it possible for hackers to access devices and mine cryptocurrencies without the user’s knowledge.
While cryptomining is legal, this mining activity can then use up a lot of resources, hence why cyber criminals opt to mine on devices that aren’t theirs. You may find you have higher electricity bills, lower battery life and slower processes. Cryptomining can be a profitable business, however, in order to be successful, you will likely have to spend a lot in advance on the resources you use.
Other security considerations
Data laws vary across the world. In many regions, legislation states the responsibility for safeguarding data lies with the company storing it. n this case, you must implement proper protection against cloud computing security attacks to avoid legal issues, such as compliance violations, and to ensure your own peace of mind.
Customer and client trust
Businesses must legally disclose data breaches, so clients can assess the effectiveness of their security measures. This can have a huge impact on trust and retention, as 87% of consumers will take their business elsewhere if they don’t trust how a company with their data. By being able to showcase how secure your operations are, you are more likely to get new customers and keep your existing ones.
Revenue loss
As a direct result of losing clients, businesses may also face revenue loss. This could also be the result of the attack itself – paying compensation to those affected by the leak or loss of their sensitive information, the resources and technology used to fix the problem and updating the security platform. Other expenses could also include lawsuits and marketing campaigns to rebuild reputation.
The average cost of a cyber-attack reached $13m in 2018, increasing by $1.4m from 2017 – installing security software could end up saving you millions.
How do I protect my data in the cloud?
There are several key features that a strong antivirus can offer to provide ultimate data security in the cloud.
If working in real-time, a security solution can keep your data safe at all times. With advanced scanning and detection, the automated process can remove human error – saving time and improving accuracy. Real-time updates will alert of any issues as soon as they arise, allowing you to respond as soon as possible. Real-time software offers constant monitoring and response, leaving no gap in protection.
Ensure your business data policy includes data backup in case of data loss. Enforcing a policy in which employees backup their work – either online or on hardware – can help save time, money and resources when managing data loss.
