Top 5 Cloud Security Practices – Every Professional Should Know

Cloud security encompasses all of the technology and procedures that secure an organization’s cloud infrastructure from both internal and external cyber threats. As more businesses embrace the cloud as the future of business, cloud security is critical to ensuring continuity. Cloud security ensures that the lights remain on, allowing organizations to concentrate on moving forward.

Security has been the primary worry of organizations exploring the public cloud since the dawn of the cloud computing age. For many companies, the concept of storing data or running applications on infrastructure they do not directly oversee seems to be intrinsically risky.

Cloud Security Monitoring’s Difficulties

  • Lack of a Proper Cloud Security Strategy

The majority of businesses shift their data from on-premise storage to the cloud without establishing an effective cloud security plan. Prior to deciding on cloud storage, important stakeholders should be aware of the following:

– How to obtain access to and modify cloud policy settings.
– How to manage their cloud assets and who should have access to them.
– How to handle backups and if offshore copies are necessary.
– Which cloud service provider will have access to their data and what activities the cloud service provider will be able to do on the data.

Without a sound plan, a business will be unable to fully realize the advantages of cloud security monitoring.

  • Lack of Context
    Cloud security monitoring necessitates the study of logs and alarms. However, they are only beneficial to a business if they are supported by a technically capable staff. Security teams must understand what they should monitor and what measures to take in response to alarms. Additionally, they should understand the types of notifications that should be prioritized to avoid serious harm to cloud data.
  • Alert Fatigue
    Cloud security solutions create a high volume of warnings and are thus somewhat noisy. This might cause IT security teams to lose sight of what they should be concentrating on. Thus, cloud monitoring systems should be set in such a way that warnings are prioritized and false positives are minimized.

Top 5 Five Best Practices for Cloud Security

1- Enhance Access Control

Traditional security procedures are unable to ward off contemporary security threats.
attacks. The current best practice is to “assume breach” and protect as if there had been one.
The attacker has gained access to the network’s perimeter. A strategy based on zero trust that confirms and protects each user’s identity, verifies the device’s health, and enforces least-privileged access. This so becomes a new security requirement.

Additional security can be added by requiring two or more of the following authentication methods:
– Something you know (typically a password)
– Something you have (a trusted device that is not easily duplicated, like a phone
– Something you are (biometrics)

  • Enforce Conditional Access Policies
    Maintain a healthy balance of security and productivity by including the manner in which a resource is accessed into access control decisions. Automate access control decisions for your cloud applications based on criteria.
  • Assure Access with the Fewest Possible Privileges
    Simplify access management in multi-cloud setups by providing a consolidated view of all rights and identities across all clouds and constantly enforcing least privilege policies to safeguard your most sensitive cloud resources.

2- Improve Your Security Posture for a Best Cloud Security

Due to the cloud’s dynamic nature and ever-growing landscape of workloads and other resources, it can be challenging to assess your company’s cloud security condition. Ascertain that you have the necessary tools for assessing present situations, identifying hazards, and mitigating them.

  • Evaluate and Strengthen Your Existing Posture
    Microsoft Defender for Cloud and Amazon GuardDuty on AWS both have hundreds of pre-configured recommendations aligned with industry best practices and regulatory requirements.
  • Stakeholder Education
    Monitor your secure score progress over time and generate rich, interactive reports to share with key stakeholders to illustrate how your security team is continuously strengthening the organization’s cloud security posture.
  • Collaborate on Policies with Your DevOps Team

Include your DevOps teams in the development of your security plan.
Assist them in comprehending and implementing critical policies, as well as in deploying application security at the start of the development lifecycle.

3- Secure Your Apps and Data

Secure data, applications, and infrastructure with a layered, defense-in-depth approach that spans identity, data, hosts, and networks.

  • Share the Responsibility
    When a business is largely based on premises, it controls the whole stack and is alone responsible for its security. Your obligations differ depending on how you utilize the cloud, with certain tasks shifting to your cloud provider.

    Infrastructure as a Service (IaaS): When applications operate on virtual machines, the IT organization has a greater responsibility for ensuring the application and operating system are safe.

    Platform as a Service (PaaS): As you migrate to cloudnative PaaS, cloud providers like as Microsoft will assume more responsibility for OS-level security.

    Software as a Service (SaaS): More responsibility is transferred away from the IT group at the SaaS level.
  • Encryption
    Encrypt data when it is at rest and in transit, and consider encrypting data in use as well.
  • Follow Security Best Practices
    Ascertain that none of your open-source dependencies are vulnerable. Additionally, educate your engineers on acceptable security procedures.

4- Defend Against Threats

Operational security postures—protect, detect, and react—should be guided by security information in order to detect and respond to rapidly emerging threats early.

  • Enable Detection for All Resource Types

Ascertain that threat detection is enabled for virtual machines, containers, databases, storage, and Internet of Things (IoT) devices, among other resources.
Microsoft Defender for Cloud has built-in threat detection for all main Azure and Amazon Web Services (AWS) resource types.

  • Modernize Your Security Information and Event Management (SIEM)
    Consider a cloud-native SIEM that expands with your requirements, using artificial intelligence to decrease noise, and does not need any equipment.
  • Integrate threat intelligence

Utilize a cloud provider that incorporates threat intelligence and delivers the context, relevance, and priority essential for you to make quicker, more informed, and proactive choices.

5- Protect The Network

The network security landscape is undergoing fast change. To stay current, your security solutions must address the expanding threat environment and make network exploitation more difficult for attackers.

  • Maintain a Robust Firewall Defense System

Even with identity and access control, configuring your firewall is critical. You need controls to safeguard the perimeter, identify hostile behavior, and prepare your reaction.
A web application firewall (WAF) guards against typical web application attacks such as SQL injection and cross-site scripting.

  • Protect Against Distributed Denial-of-Service (DDoS) Attacks
    Protect online assets and networks against harmful traffic directed at application and network layers in order to ensure availability and performance while keeping operational costs down.
  • Create a Network Using Microsegments

A flat network enables attackers to move laterally more easily.
Develop an understanding of topics such as virtual networking, subnet provisioning, and IP addressing. To enable zero-trust networking, use microsegmentation and the idea of micro-perimeters.
