Cyber Security

An organisation has numerous systems and data, and sometimes, they become overloaded, so they need the cloud to store their essential data. The cloud is a beneficial system because it offers various functions, including data storage, software, and organisational infrastructure, that can be accessed anywhere and at any time, as long as you have an internet connection. With so much data stored in the cloud, cloud security is essential to provide a layer of protection, keeping your crucial data and information safe from cloud security issues.

What is cloud security?

Cloud security is a combination of policies, technologies, and practices used to protect data, applications, and infrastructure stored in the cloud. It ensures that data in the cloud is more secure and reduces the risk of data security threats. Additionally, cloud security helps protect this information from unauthorised access or manipulation. Cloud security applies to services such as Google Cloud, AWS, and Microsoft Azure. In other words, cloud security is your digital safety net in the cloud.

How does cloud security work?

Cloud security involves using various tools and systems to monitor, control, and protect data stored online. This includes implementing firewalls, identity verification, encryption, and regular updates. For instance, access to cloud data is typically restricted through role-based permissions, granting full control only to those with authorised access to the cloud system. Therefore, implementing security measures will make it more difficult for cyber attackers to breach the data system.

However, cloud security does not provide complete protection against cyber threats, as risks such as malware and phishing can still occur if the cloud security strategy is not well designed. If the security strategy is better designed and tailored to your specific needs, you will be able to protect your cloud system more effectively.

Why is cloud security important?

In the digital and technological world, where cyber threats are rampant and prevalent, having a robust protection system is essential. If an organisation has a lot of necessary infrastructure and applications stored in the cloud, not having cloud security can cause significant impact and losses.  Effective cloud security also helps companies remain compliant with relevant privacy laws and industry standards.  By improving industry standards, the organisation will gain higher credibility and earn more trust from clients.

Benefits of cloud security

Centralised security

One of the key benefits of cloud security is that all data and systems are safeguarded in a single, centralised location. Rather than managing various systems across multiple sites, businesses can oversee everything from one central point of control. With a centralised security system, it is easier to monitor information systems, and mobility becomes more efficient. Checking data in the cloud saves users a lot of time.

Reduced costs

One way to ensure an organisation can operate in the long term is to manage its finances effectively and minimise excessive costs whenever possible. All of the organisation’s needs and priorities must be considered, and it would be better to have a security system that can reduce costs, such as cloud security. When using cloud security, many security features come built-in with cloud services, which means lower upfront costs and fewer ongoing maintenance bills.

Greater visibility

Clouds have a structured and organised form that offers clear insight into their network. You can identify which users are accessing the cloud system and monitor for any suspicious activities. This visibility is crucial for organisations, as it helps them prevent potential threats before they escalate into serious problems and risks.

Data protection

The primary purpose and function of the cloud is to provide extra protection for existing data. Data stored in the cloud will minimise the risk of cyber attacks that can easily steal information and compromise systems. In addition, it also features handy tools such as encryption and backup to secure your data, preventing it from being deleted, and strict access controls that prevent unauthorised access to the system. Cloud providers also help protect sensitive information such as financial records, customer details, and internal files.

Advanced threat detection

With advanced threat detection tools, systems can identify unusual patterns or risky behaviour and respond quickly, thereby enhancing your system’s security. These tools are very helpful in preventing high risks, especially since they monitor unusual activity 24/7. Therefore, cloud systems are crucial for safeguarding sensitive organisational data.

Cloud compliance

Compliance with legal and industry regulations is made easier with cloud compliance tools integrated into modern systems. These tools include access logs, audit trails, data encryption, and others designed to support regulations such as the Australian Privacy Principles and the GDPR. It is beneficial for organisations such as hospitals, financial institutions, government agencies, and educational institutions that manage sensitive and critical data for numerous individuals and clients. Having cloud compliance also means that the organisation has high credibility and quality, which enhances its performance.

Types of cloud security solutions

Data loss prevention (DLP)

In cloud security management, Data Loss Prevention (DLP) is a tool that provides restrictions to prevent sensitive information from being leaked or shared with external parties. Using advanced and precise scanning technology, data can remain secure and protected. Additionally, these tools give companies greater control over how data is processed and transferred.

Identity and access management (IAM)

Identity and Access Management (IAM) provides stronger access protection because this system ensures that only individuals with familiar and trusted identities can access it. With IAM, cyber attackers will find it difficult to steal information in the cloud due to multi-factor authentication and user roles that are only known to internal parties. It also facilitates accountability and seamless user access across cloud systems.

Public key infrastructure (PKI)

Public Key Infrastructure (PKI) uses digital certificates and encryption keys to protect data stored in the cloud. This system identifies which users have access and distinguishes internal users from external ones. Furthermore, PKI allows businesses to secure emails, verify devices, and protect communications.

PKI is widely used in things such as SSL certificates for websites and secure file sharing. By encrypting information and verifying identities, PKI enables organisations to build trust with users while keeping sensitive content secure and preventing it from falling into the wrong hands.

Security information and event management (SIEM)

Security Information and Event Management (SIEM) is a handy tool for detecting potential threats in your system. These tools help IT teams quickly identify suspicious activity, such as unusual login times or large file downloads. SIEM systems generate alerts and reports that guide rapid response to potential threats.

Cloud computing security: risks vs. threats vs. challenges

In cloud computing security, there are many risks, threats, and challenges that you need to be aware of to understand cloud security and implement it effectively.

Cloud security risks

Data breaches

In cloud computing, data breaches are a significant challenge often faced in network systems. A lack of protection layers, such as the absence of strong passwords, multi-factor authentication, or unpatched software, causes these threats. As much as possible, utilise adequate protection or security systems to prevent data breaches, as these can lead to phishing, data theft, and damage to your organisation’s reputation due to privacy data leaks.

Inadequate identity access management (IAM)

If identity and access management aren’t set up correctly, users might have too much access, or unauthorised users might sneak in. Therefore, intense and structured IAM must be implemented to prevent outsiders from easily accessing the system and putting the organisation at significant risk. Organisations must implement strict IAM policies to control access, ensuring every user has only the necessary access.

Insecure APIs

APIs (Application Programming Interfaces) allow various systems to communicate. However, if they are not built securely, they can become an entry point for attackers. Insecure APIs may lack proper authentication, expose sensitive information, or contain coding flaws. Since many cloud apps rely heavily on APIs, a single weakness can affect multiple services. Keeping them secure means regular testing, strict access controls, and updated documentation.

Insufficient cloud configuration management

Misconfigured cloud settings make it easy for attackers to spread various threats. Ensuring secure configuration management is essential, as even minor mistakes can have a significant impact on your organisation. This problem often occurs when teams rush to implement systems without checking the details. However, cloud service providers provide tools to manage configurations, but these tools must be used correctly and effectively.

Shared infrastructure vulnerabilities

In a public cloud environment, the platform is shared by many internal users. This shared infrastructure can have both positive and negative effects. This is because if one user’s system has a weakness, it will affect other users. Therefore, each user is required to secure their data and apps as it is their responsibility to avoid high risk.

Shadow IT

Shadow IT refers to situations where employees use services without obtaining prior approval from their company. This can include personal cloud accounts, online tools, or shared folders. While these tools are often used with good intentions, they can bypass security measures and create vulnerabilities. Without oversight from the IT department, data may be exposed or lost. Therefore, it is crucial to provide user training and implement strict policies to prevent such incidents.

Human error

In the digital world, even a minor human error can lead to significant consequences or major issues within a company. The best way to address this problem is by reducing and minimising the likelihood of human error through clear training and well-defined protocols. Additionally, consistently double-checking work and maintaining regular monitoring can further help mitigate the risk of human mistakes.

Cloud security threats

Account hijacking

One significant threat to a company is when an unauthorised user gains control of a cloud account, often due to stolen login credentials. These incidents can lead to serious consequences such as data theft, phishing, and the distribution of malware. To protect against this, it is crucial to implement multi-factor authentication, monitor account activity, and regularly update passwords.

Denial of service attacks

Denial-of-service (DoS) attacks flood cloud servers with fake requests, causing systems to slow down or crash. When services go offline, it disrupts business, affects customers, and can damage trust. These attacks don’t always steal data, but they stop users from accessing what they need.

Insider threats

Significant problems in a company are not only caused by external parties, such as cyber threats but can also originate from internal staff within a company. This can take the form of stealing company data, deleting files, or sabotaging the system, as insider threats often have access to the company’s system. In this case, robust access controls and well-defined policies are essential.

Cloud malware injection

Cloud malware injection occurs when attackers insert malicious code into cloud services. Once inside, the malware can steal data, spy on users, or disrupt systems. This can happen through fake updates, unsecured uploads, or weak third-party tools. Since cloud apps run online, even small gaps in security can be exploited.

Cloud security challenges

Complex regulatory compliance

Cloud services frequently store data in multiple locations and manage vast amounts of information, making compliance a challenging task. Keeping up with changing regulations, especially across different regions, can be demanding. Furthermore, even minor errors can have significant repercussions. To address this, organisations should partner with providers that prioritise compliance and utilise tools like audit logs and access controls to remain informed and aligned with evolving laws.

Lack of visibility

Cloud systems are often distributed across multiple networks, which makes comprehensive monitoring difficult. This lack of visibility can lead to issues such as shadow IT and data leaks. To enhance visibility, it is highly recommended to use tools like access tracking and activity alerts.

Lack of cloud security professionals

Skilled cloud security experts are in short supply, and it’s becoming harder for businesses to find and keep them. Without the right people in place, systems may be misconfigured, threats could go unnoticed, and updates might be delayed. Smaller businesses are hit hardest, often relying on general IT staff who lack specialised cloud training. 

Cloud data governance

Effective data governance involves understanding where your data is located, how it’s utilised, and who has control over it. In the cloud, this becomes more challenging because data may be stored in different locations or handled by third-party applications. Poor governance can lead to unauthorised access, loss of data ownership, or legal issues. Businesses require robust policies to categorise data, manage access, and ensure consistent handling across all systems.

Managing a rapidly evolving attack surface

The more cloud services a business utilises, the more vulnerabilities arise for attackers. Constantly evolving features, users, and integrations alter the security landscape. This expansion creates a wider attack surface that requires ongoing monitoring.

Multi-cloud security

Using multiple cloud providers can provide great flexibility, but it also adds complexity in terms of security. With multi-cloud security, companies must first consider different systems and rules. However, to handle multi-cloud security, businesses need tools that can work across all providers and policies that apply to all of them, not just one system.

Cloud security best practices

Encrypt Data at Rest and in Transit

Encryption is one of the simplest and strongest defences available. It scrambles your data into unreadable code unless someone has the correct key. Encrypting data at rest means it’s protected while stored in the cloud. Thus, it protects against eavesdropping, hacking, and accidental leaks. 

Utilise Strong Access Controls

Sometimes, not all users or employees can have access to all systems and apps. If all employees have access, then shadow IT or insider threats can potentially occur. Therefore, implementing robust access controls can help companies prevent such problems and mitigate risks, including cyberattacks.

Implement a Comprehensive Backup and Recovery Strategy

A backup and recovery plan ensures you can quickly restore your data if it’s lost due to cyberattacks, system errors, or human mistakes. Store backups in multiple secure locations and test them regularly to ensure they are functional. Cloud platforms typically offer built-in backup options, so utilise them wisely.

Perform Regular Security Assessments

Performing regular security assessments helps identify vulnerabilities before attackers can exploit them, thereby preventing cloud security issues. It includes scanning for bugs, reviewing configurations, testing access permissions, and checking compliance with security standards. These assessments can be done internally or through third-party services.

Adopt a Zero Trust Security Model

Zero trust means never automatically trusting anyone or anything, inside or outside your network. Every request must be verified before access is granted. This model assumes threats could come from anywhere, so it limits access and constantly checks for suspicious activity.
