Introduction – Cloud Security Services

As increasing number of organizations move their applications, databases and businesses to the cloud, security of digital resources have now become extremely vital. Cloud security services allow organizations to safeguard their sensitive data, thwart cyber attacks, maintain compliance and ensure business continuity.

Security in the cloud is a shared responsibility with your cloud provider. As well as securing the cloud infrastructure, cloud providers will hand over responsibility to secure applications, accounts, configurations and data.

What today‘s cloud security should be much more than just an antivirus and firewall security. Today‘s cloud security should involve Identity Management, Encryption, Detection & Response, Audit & Compliance Monitoring, Workload Protection, Vulnerability Management and 24×7 Security Monitoring. The protection helps the organization to reduce the risk while supporting remote workforces, cloud native applications and digital transformation.

Provides a brief overview of the Cloud security services, examines the major security threats in Cloud computing and reviews the technologies and best practices companies should employ to construct secure Cloud environment. 

What Are Cloud Security Services?

Security services for the cloud are technologies, policies and managed services to secure the cloud systems, applications and data from intrusion, cyber-attacks, and operational risks.

These services help organizations secure resources hosted in:

• Public clouds

• Private clouds

• Hybrid cloud environments

• Multi-cloud deployments

Cloud security is a combination of many types of security controls, such as identity management, encryption, network security, monitoring of compliance, and threat detection.

Why Cloud Security Matters

Cloud computing provides flexibility and scalability. But it also raises new security issues.

Organizations often store:

• Customer information

• Financial records

• Intellectual property

• Employee data

• Business applications

• Confidential documents

If not properly protected, these assets could be targeted by a cyberattack, exposed accidentally, or accessed by an unauthorized person.

Strong cloud security helps organizations:

• Protect privacy To avoid this, the details about celebrities’ birth dates, mobile phone numbers and addresses are concealed.

• Minimize the cyber dangers

• Retain customer confidence

• Comply with regulatory requirements
• Secure business continuity

Common Cloud Security Threats 

The foundation of a safe cloud environment is knowing at least some of the prevalent threats.

Data Breaches

Unauthorized access to sensitive data is still one of the major risks in secure cloud computing.

Data breaches can occur due to:

• Weak passwords

• Misconfigured storage

• Stolen credentials

• Insider threats

Potential results could include financial loss, legal liability, damage to reputation.

Misconfigured Cloud Resources

Configuration errors constitute one of the most prevalent category of cloud security breaches.

Examples include:

• Publicly accessible Storage buckets

• Open databases

• Incorrect fire wall rules

• Too many user privileges

Reconsidering the configuration on a regular basis mitigates these risks.

Account Hijacking

Cybercriminals may attempt to gain access to cloud accounts through:

• Phishing attacks

• Credential theft

• Password reuse

• Malware

The implementation of powerful authentications drastically diminishes the probability of a hack.

Malware and Ransomware

But if a system connects to the cloud, it may be subject to other threats, such as malware.

Attackers may attempt to:

• Encrypt business data on all servers.

• Steal sensitive files

• Disrupt operations

• Demand ransom payments.

Regular back-ups and security monitoring reduce the effect of these attacks.

Insider Threats

Every security incident is not caused by external sources.

Employees, contractors, and organizations that have been granted too many rights, may inadvertently or on purpose disclose vital data.

Adopting least privilege can help minimize insider threats.

Understanding the Shared Responsibility Model

A fundamental concept in cloud cybersecurity is the shared responsibility model.

Responsibilities are split between the cloud provider and the customers.

Cloud Provider Responsibilities

Most providers are responsible for securing:

• Physical data centers

• Networking infrastructure

• Hardware

• Virtualization platforms

• Core cloud services

Customer Responsibilities

Organizations are typically responsible for protecting:

• User accounts

• Applications

• Operating systems (where applicable)

• Data

• Access permissions

• Security configurations

What the exact roles will be depends on what model the business is using Infrastructure as a Service, Platform as a Service, or Software as a Service.

This model is essential to understand to avoid holes in security if mistaken assumptions are made.
