Cloud Application Security: Threats, Benefits, & Solutions

As your organization adopts a hybrid IT infrastructure, there are more ways for hackers to steal your sensitive data. 

This is why cloud application security is a critical part of data protection. 

It allows you to secure your cloud-based applications from cyber threats while ensuring your data is safe. 

This post will walk you through cloud application security, including its importance. We will also discuss the main cloud application security threats and how to mitigate them.

What is Cloud Application Security

Cloud application security refers to the security measures taken to protect cloud-based assets throughout their development lifecycle. These security measures are a framework of policies, tools, and controls that protect your cloud against cyber threats. 

Here is a list of security measures that cloud application security may involve:

• Compliance with industry standards such as CIS benchmarks to prevent data breaches.

• Identity management and access controls to prevent unauthorized access to your cloud-based apps.

• Data encryption and tokenization to protect sensitive data.

• Vulnerability management through vulnerability scanning and penetration testing.

• Network perimeter security, such as firewalls, to prevent unwanted access.
  

The following are some of the assets that cloud security affects:

• Third-party cloud providers like Amazon AWS,  Microsoft Azure, and Google GCP.

• Collaborative applications like Slack and Microsoft Teams.

• Data Servers.

• Computer Networks.
  

Why is Cloud Application Security Important

Cloud application security is becoming more relevant as businesses migrated their data to the cloud in recent years. 

This is especially true for companies with a multi-cloud environment. These types of environments create a larger attack surface for hackers to exploit.

According to IBM, the cost of a data breach in 2022 was $4.35 million. And this represents an increase of 2.6% from the previous year.

The report also revealed that it took an average of 287 days to find and stop a data breach in a cloud environment.  This time is enough for hackers to steal sensitive data and really damage your assets. 

Here are more things that can go wrong if organizations don’t pay attention to cloud security:

• Brand image damage:
  

A security breach may cause a brand’s reputation to suffer and a decline in client confidence. 

During a breach, your company’s servers may be down for days or weeks. This means customers who paid for your services will not get access in that time. 

They may end up destroying your brand’s image through word of mouth.

• Lost consumer trust:
  

Consumer confidence is tough to restore after being lost due to a security breach. Customers could migrate to rivals they believe to be more secure.

• Organizational disruption:
  

A security breach may cause system failures preventing employees from working.  This, in turn, could affect their productivity. You may also have to fire employees tasked with ensuring cloud security.

• Data loss:
  

You may lose sensitive data, such as client information, resulting in legal penalties. Trade secrets theft may also affect the survival of your organization. Your competitors may steal your only leverage in the industry.

• Compliance violations:
  

You may be fined for failing to comply with industry regulations such as GDPR. You may also face legal consequences for failing to protect consumer data.

What are the Major Cloud Application Security Threats

The following is a list of the major cloud application security threats:

• Misconfigurations:
  

Misconfigurations are errors made when setting up cloud-based applications. They can occur due to human errors, lack of expertise, or mismanagement of cloud resources.

Examples include weak passwords, unsecured storage baskets, and unsecured ports.  Hackers may use these misconfigurations to access critical data in your public cloud.

•  Insecure data sharing:
  

This is the unauthorized or unintended sharing of sensitive data between users. Insecure data sharing can happen due to a misconfiguration or inappropriate access controls.

It can lead to data loss, breaches, and non-compliance with regulatory standards.

• Limited visibility into network operations:
  

This is the inability to monitor and control your cloud infrastructure and its apps. Limited network visibility prevents you from quickly identifying and responding to cyber threats.  

Many vulnerabilities may go undetected for a long time. Cybercriminals may exploit these weak points in your network security and gain access to sensitive data. 

• Account hijacking:
  

This is a situation where a hacker gains unauthorized access to a legitimate user’s cloud account. 

The attackers may use various social engineering tactics to steal login credentials. Examples include phishing attacks, password spraying, and brute-force attacks. 

Once they access the user’s cloud account, they can steal data or damage assets from within.

• Employee negligence and inadequately trained personnel:
  

This threat occurs when employees are not adequately trained to recognize, report and prevent cyber risks.

It can also happen when employees unintentionally or intentionally engage in risky behavior. For example, they could share login credentials with unauthorized users or set weak passwords. 

Weak passwords enable attackers to gain entry into your public cloud. Rogue employees can also intentionally give away your sensitive data.

• Compliance risks:
  

Your organization faces cloud computing risks when non-compliant with industry regulations such as GDPR, PCI-DSS, and HIPAA. 

Some of these cloud computing risks include data breaches and exposure of sensitive information.  This, in turn, may result in fines, legal repercussions, and reputational harm.

• Data loss:
  

Data loss is a severe security risk for cloud applications. It may happen for several causes, including hardware malfunction, natural calamities, or cyber-attacks. 

Some of the consequences of data loss may be the loss of customer trust and legal penalties. 

• Outdated security software:
  

SaaS vendors always release updates to address new vulnerabilities and threats. Failing to update your security software on a regular basis may leave your system vulnerable to cyber-attacks.

Hackers may exploit the flaws in your outdated SaaS apps to gain access to your cloud.

• Insecure APIs:
  

APIs are a crucial part of cloud services but can pose a severe security risk if improperly secured. 

Insecure APIs and other endpoint infrastructure may cause many severe system breaches. They can lead to a complete system takeover by hackers and elevated privileged access.

How to Mitigate Cloud Application Security Risks

The following is a list of measures to mitigate cloud app security risks:

• Conduct a thorough risk analysis:
  

This entails identifying possible security risks and assessing their potential effects.  You then prioritize correcting the risks depending on their level of severity. 

By conducting risk analysis on a regular basis, you can keep your cloud environment secure. You’ll quickly understand your security posture and select the right security policies.

• Implement a firm access control policy:

• 
  

Access control policies ensure that only authorized users gain access to your data. They also outline the level of access to sensitive data based on your employees’ roles.

A robust access control policy comprises features such as:

• Multi-factor authentication

• Role-based access control

• Least Privilege Access

• Strong password policies.  
  

• Use encryption:
  

Encryption is a crucial security measure that protects sensitive data in transit and at rest. This way, if an attacker intercepts data in transit, it will only be useful if they have a decryption key.

Some of the cloud encryption solutions you can implement include:

• Advanced Encryption Standard (AES)

• Rivest -Shamir-Addleman (RSA)

• Transport Layer Security (TSL)
  

• Set up data backup and disaster recovery policies: 
  

A data backup policy ensures data is completely recovered in case of breaches. You can always recover the lost data from your data backup files. 

Data backup systems also help reduce the impact of cyberattacks as you will restore normal operations quickly.

Disaster recovery policies focus on establishing protocols and procedures to restore critical systems during a major disaster. This way, your data security will stay intact even when disaster strikes.

• Keep a constant watch over cloud environments:
  

Security issues in cloud settings can only be spotted through continuous monitoring. Cloud security posture management tools like Prevasio can help you monitor your cloud for such issues. 

With its layer analysis feature, you’ll know the exact area in your cloud and how to fix it.

• Test and audit cloud security controls regularly:
  

Security controls help you detect and mitigate potential security threats in your cloud. Examples of security controls include firewalls, intrusion detection systems, and database encryption. 

Auditing these security controls helps to identify gaps they may have. And then you take corrective actions to restore their effectiveness.

Regularly evaluating your security controls will reduce the risk of security incidents in your cloud.

• Implement a security awareness training program:
  

Security awareness training helps educate employees on cloud best practices. When employees learn commonly overlooked security protocols, they reduce the risks of data breaches due to human error.  

Organize regular assessment tests with your employees to determine their weak points. This way, you’ll reduce chances of hackers gaining access to your cloud through tactics such as phishing and ransomware attacks.

• Use the security tools and services that cloud service providers offer:
  

Cloud service providers like AWS, Azure, and Google Cloud Platform (GCP) offer security tools and services such as:

• Web application firewalls (WAF),

• Runtime application self-protection (RASP),

• Intrusion detection and prevention systems
  

• Identity and access management (IAM) controls
  

You can strengthen the security of your cloud environments by utilizing these tools. However, you should not rely solely on these features to ensure a secure cloud. You also need to implement your own cloud security best practices.

• Implement an incident response strategy:
  

A security incident response strategy describes the measures to take during a cyber attack. It provides the procedures and protocols to bring the system back to normal in case of a breach.

Designing incident response plans helps to reduce downtime. It also minimizes the impact of the damages due to cyber attacks.

• Apply the Paved Road Security Approach in DevSecOps Processes: 
  

DevSecOps environments require security to be integrated into development workflows and tools. This way, cloud security becomes integral to an app development process. 

The paved road security approach provides a secure baseline that DevSecOps can use for continuous monitoring and automated remediation.
