What is cloud security? How to improve security on the cloud?

Explore the essentials of cloud security and learn how to safeguard your data and applications in the cloud.

Cloud computing has become increasingly popular as more and more organizations turn to the cloud to store and manage their data and applications. A large portion of the world’s corporate data is stored in the cloud. However, with this increased reliance of the cloud comes an increased need for cloud security.

Cloud security is an umbrella term that covers the tools and processes used to protect data, systems, and networks in cloud computing environments. In this article, we’ll explore the varied types of cloud security and how to minimize the risk of a security incident.

Types of Cloud Security

Here are the different types of cloud security that organizations can implement to protect their data and applications on the cloud:

Intrusion Detection:

Intrusion Detection Systems (IDS) monitor and protect cloud-based resources and infrastructure. These systems can analyze network traffic, system logs, and other data sources to identify suspicious activity and alert administrators to potential security breaches. Once an intrusion is detected, it can then be blocked or reported to the appropriate authorities. IDS can also help organizations comply with regulatory requirements and industry standards for data security.

Identity and access management (IAM):

Out of 90% of data breach cases faced by financial institutions, more than 60% were cases of identity abuse. This data pinpoints the dire need for Identity and Access Management in the cloud networks to ensure that only authorized users can access sensitive data and systems.

IAM systems manage and secure access to cloud-based resources, such as servers, storage, and applications. They typically have tools and technologies for managing user identities and authentication, authorization, and access control policies. This includes creating and managing user accounts, defining and enforcing access controls, and monitoring and auditing user activity.

Email Security:

Email is often used as a vector for cyber-attacks, such as phishing, malware, and ransomware, which can compromise the security of an organization’s IT infrastructure and data. Email security protects organizations and their customers from these threats by providing a set of tools and technologies that can be used to secure email communications and data.

Data Loss Prevention:

The cloud has become an increasingly popular target for data breaches due to its vast storage of sensitive information. Data loss prevention (DLP) is a set of processes and technologies used to stop sensitive data from being leaked outside of an organization. Some common DLP techniques include data encryption, access control, and activity monitoring.

Best Practices for Improving Cloud Security

Choose a reliable provider

Not all providers adhere to the same standards; some may cut corners regarding security to save time or money. Do your research and choose a provider with a good security reputation. Ask other businesses in your industry which providers they use and why they trust them. Once you’ve narrowed down your options, find out what kinds of data encryption they offer, what authentication methods they use, and what physical security measures are in place to protect their data centers. Make sure you understand their policies before entrusting them with your data.

Enable two-factor authentication

2FA adds an extra layer of security by requiring users to provide two forms of authentication before accessing sensitive data or systems. The additional authentication factor can be something the user knows (such as a password) or something the user has (such as a security token or a mobile device). There are different ways to enable 2FA, such as using Security Tokens, SMS, or App-based authentication. It is important to ensure that the 2FA solution is easy to use and does not create an additional burden on users while providing the necessary security level.

Encrypting data in transit

As data is increasingly transmitted over public networks, the risk of interception and theft grows. Still, 51% of companies don’t use encryption to protect their data stored on the cloud. Encrypting data in transit can help protect it from eavesdroppers and attackers. This can be done using various encryption protocols such as SSL/TLS. Encrypting data in transit is essential not just for data privacy but also for compliance with regulations such as HIPAA, PCI-DSS, etc. Additionally, it is vital to regularly review and update encryption protocols and standards to ensure they are up-to-date and secure.

Secure your user endpoints

User endpoints are the weak link in any organization’s security posture. Endpoints are where users access company data and applications and are the most likely entry point for attackers. By securing user endpoints, organizations can prevent or mitigate these threats, protecting the company and its client’s data, and preserving the trust and reputation of the company. It involves implementing security measures such as firewalls, antivirus software, and endpoint encryption to protect these devices from malware and other cyber threats.

Providing adequate security training to employees

Employees are often the first line of defense against security threats, and ensuring that they are aware of security best practices and policies can help reduce the risk of data breaches and other security incidents. Providing adequate training to employees on identifying and responding to security threats, such as phishing attempts and other forms of social engineering, can help create a culture of security within the organization.

Use a Cloud Access Security Broker (CASB) solution

A CASB solution acts as a gatekeeper, monitoring and controlling access to the cloud resources and enforcing security policies to protect sensitive data and comply with regulatory requirements. CASB solutions can provide features such as threat protection, data loss prevention, and compliance reporting. Implementing a CASB can effectively improve cloud security by providing visibility and control over cloud usage and securing data in the cloud.

Cloud Security Challenges

There’s no surprise that cloud security issues are the top concern of enterprises. As the world increasingly moves to the cloud for its computing needs, it’s important to understand the security challenges inherent in this new environment. One of the main challenges is that the cloud is a shared environment, meaning that multiple organizations use the same infrastructure. This can lead to security breaches if one organization’s data is compromised.

Another challenge is that cloud providers are responsible for the security of their infrastructure, which means that they may have a different level of security than an on-premises environment. Additionally, cloud providers may have a different level of visibility into their networks than on-premises environments. This can make it more difficult to detect and respond to threats.

Finally, because the cloud is constantly changing, it can be difficult to keep up with security patches and updates. This can leave organizations vulnerable to attack if they’re not using the latest versions of software and security tools. To address these challenges, organizations need to take a proactive approach to security. They need to consider how they can segment their data and applications, and deploy security controls at multiple levels.
