Top Security Issues in Cloud Computing
Even though cloud security services have ushered in flexible ways to store, transmit and share data, many organisations feel reluctant to use them. This may be because of the many security concerns that surround the integrity of data in the cloud. From Denial-of-Service (DoS) attacks and malware injections to accidental data losses and internal vulnerabilities, these threats loom large. But they also have viable solutions when dealt with strategically.

But before beginning, do not forget to understand what is cloud security and discuss the principles of security in cloud computing! Also, remember that there is a significant difference in cloud security vs cyber security and how to deal with them.

What is infrastructure security in cloud computing?

Infrastructure security encompasses not only defence against classic cyberattacks, but also defence against natural catastrophes and other calamities. It also touches on the subject of resilience, which is concerned with how an organisation recovers after an attack or other interruption. The ultimate goal is to improve security and reduce downtime, as well as the accompanying customer attrition, brand and reputation damage, and compliance costs that firms incur.

Cloud computing has transformed the way organisations use, share and store their data, business applications and workloads. Scalability, resilience, flexibility and efficiency are the top advantages of this technology that cloud security management helps achieve. However, despite the potential gains, several enterprises have been hesitant to adopt the cloud because of the security concerns. With terabytes of data getting pooled into public cloud resources, they have become an enticing target for cyber thieves.

What are security risks of cloud computing?

After understanding what is data security in cloud computing, Let’s look into the top challenges of cloud computing security that affect the adoption of cloud technology and information security and how cloud security protects from these.

DDoS Attacks
Data security in cloud computing have been affected by Distributed Denial of Service (DDoS) attacks in the past few years. DDoS attacks in cloud security services are strategised to overwhelm web servers and make them insensitive to legitimate access requests. A successful DDoS attack can render a website useless for hours and even days. This can lead to loss of revenue, client trust and brand authority.

In their early days, the sheer amount of the resources used by cloud computing platforms had made it difficult to execute DDoS attacks. With the increasing number of devices and applications now connected to the IoT, however, this threat is impending. An experienced cloud data privacy service provider can secure their client’s cloud environment by providing a huge bandwidth, using intrusion detection systems, configuring firewall rules to keep out malicious IP addresses and regularly updating the security patches.

Insecure Access Points

A prime benefit of the cloud is that it can be accessed from any location or device. Even so, the same can become a major threat when the interfaces and APIs that the users interact with are not secure. When hackers uncover such vulnerabilities, they can misuse them.

The flexibility of access to cloud data security platforms has also made them prone to phishing and social engineering attacks. Once cyber thieves acquire the login details, they can easily break from anywhere into a system that is available. Employees must be well-acquainted with ways to safeguard their login credentials against such attacks of cloud security in cloud computing, especially when they use their personal devices or computer systems outside the office premises to access the data in the cloud.

One of the measures to dilute this risk is to use a behavioural web application firewall that observes HTTP requests for a website and ensures that only legitimate traffic has access to it.

Inadvertent Data Loss
The DDoS attacks that a cloud network security is vulnerable to are diversions for bigger data thefts. Ransomware and malicious tampering by sacked employees are also some threats to security and privacy in cloud computing. In addition, a business can lose its data from the cloud due to accidental deletion by the authorised workforce, including the senior managers.

Natural disasters can also lead to data loss. Google lost all data at one of the data centres in Belgium when its power grids were struck by lightning in 2015 ¹

To address these problems, it is important to have a strong disaster recovery process with data backups. Small and medium enterprises can involve their cloud service provider in the process of cloud networking and security. Furthermore, the user IDs of employees who get terminated from the company and the ones who voluntarily resign should be disabled with immediate effect.

Internal Vulnerabilities
Cloud computing platforms who offer network security in cloud computingcan also have internal system vulnerabilities. The networks that have complex architectures and multiple third-party platforms are particularly prone to these issues. If such vulnerabilities become known to attackers they can be easily used against the business owning the data. With a good system for patches and upgrade protocols along with network monitoring setups, this threat can be addressed.

When you are working with a recognised and trusted cloud service provider to achieve network level security in cloud computing, it is feasible to surmount the cloud computing security problems. Tata Tele Business Services uses a harmonised combination of security tools and monitoring solutions to ensure that your data stays safe in the cloud. We offer secure cloud services and cloud security tools to help you capitalise upon the benefits of data storage flexibility, automatic application updates, better collaboration, mobility and reduced fixed costs of data maintenance.

Consult a renowned cloud security service provider and discuss the different cloud security services with them to better understand how to improve security in cloud computing. Furthermore, you must also understand how security gets integrated in cloud computing at your own level to better deal with cloud storage security risks. Also, if possible, start utilizing software as a service security in cloud computing for better results.
