Cloud Computing and Cloud Security

What is Cloud Computing?

Setting up your business for future achievement begins with changing from on-premises equipment to the cloud for your figuring needs. The cloud gives you admittance to additional applications, further develops information openness, assists your group with teaming up more actually, and gives simpler substance to the board. Individuals might have differing opinions about cloud changes because of safety concerns, however, a dependable cloud service provider (CSP) can reassure you and guard your information with profoundly secure cloud administrations. In this blog we will explain you multiple types of clouds computing environments, as well as cloud security issues and solutions. We will also give you tips on choosing a cloud service provider

Cloud security, or cloud computing security, is an assortment of security efforts intended to safeguard cloud-based foundations, applications, and information. These actions guarantee client and gadget verification, information, asset access control, and information security assurance. They additionally support administrative information consistency. Cloud security is utilized in cloud conditions to shield an organization’s information from distributed denial of service (DDoS) assaults, malware, programmers, and unapproved client access or use.

Types of Cloud Environments

When looking for cloud-based security, you’ll find three main types of cloud environments to choose from. The top options on the market include public clouds, private clouds, and hybrid clouds. Each of these environments has different security concerns and benefits, so it’s essential to know the difference between them:

  • Public Cloud: Public cloud services are hosted by third-party cloud service providers. A company doesn’t have to set up anything to use the cloud since the provider handles it all. Usually, clients can access a provider’s web services via web browsers. Security features, such as access control, identity management, and authentication, are crucial to public clouds.

  • Private cloud: Private clouds are commonly safer than public clouds, as they’re normally committed to a solitary gathering or client and depend on that gathering or the user’s firewall. The isolated nature of private clouds assists them in keeping their system secure from outside attacks since they’re just opened by one association. In any case, they actually face security challenges from certain dangers, like social engineering and breaches. These clouds can likewise be challenging to scale as your organization’s necessities grow.

  • Hybrid cloud: Hybrid clouds combine the scalability of public clouds with greater control over the resources that private clouds offer. These clouds connect multiple environments, such as a private cloud and a public cloud, that can scale more easily based on demand. Successful hybrid clouds allow users to access all their environments in a single integrated content management platform.

Importance of Cloud Security

Cloud security is fundamental since most associations are now utilizing distributed computing in some structure. As the pace of innovation in the cloud and the availability of new tools and services continues to explode, Gartner® forecasts worldwide public cloud end-user spending to reach nearly $600 billion in 2023

IT experts stay concerned about moving more information and applications to the cloud because of safety, administration, and consistency issues when their substance is put away in the cloud. They stress that sensitive business data and protected innovation might be uncovered through unplanned holes or due to progressively refined cyber-attacks.

An essential part of cloud security is centered around safeguarding information and business content, for example, client orders, secret plan reports, and monetary records. Preventing breaches and information theft is important for keeping up with your clients’ trust and safeguarding the resources that add to your upper hand. Cloud security’s capacity to guard your information and resources makes it vital to any organization switching to the cloud.

Benefits of cloud computing

Security in cloud computing is urgent to any organization hoping to keep its applications and information safeguarded from troublemakers. Keeping areas of strength for a security pose assists associations with accomplishing the now generally perceived advantages of cloud computing. Cloud security accompanies its own benefits too, assisting you with accomplishing lower forthright expenses, decreased continuous functional and administrative expenses, simpler scaling, increased reliability and availability, and improved DDoS protection.

Here are the top security benefits of cloud computing:
  •  Lower upfront cost: One of the biggest advantages of using cloud computing is that you don’t need to pay for dedicated hardware. Not having to invest in dedicated hardware helps you initially save a significant amount of money and can also help you upgrade your security. Cloud service providers(CSP) will handle your security needs proactively once you’ve hired them. This helps you save on costs and reduce the risks associated with having to hire an internal security team to safeguard dedicated hardware.

A CSP will deal with all your security needs for you, eliminating the need to pay for staff to give manual security updates and designs. You can likewise appreciate more prominent security, as the CSP will have master staff ready to deal with any of your security issues for you.
  • Increased reliability and availability: You really want a protected approach to get to your information right away. Cloud security guarantees your information and applications are promptly accessible to approved clients. You’ll constantly have a reliable technique to get to your cloud applications and data, assisting you with rapidly making a move on any potential security issues.
  • Centralized security: Cloud computing gives you a centralized location for information and applications, with numerous endpoints and gadgets requiring security. Security for distributed computing midway deals with every one of your applications, devices, and information to guarantee everything is protected. The centralized location permits cloud security organizations to all the more effectively perform undertakings, for example, executing calamity recuperation plans, smoothing out network occasion observing, and upgrading web filtering.
  • Greater ease of scaling: Cloud computing allows you to scale with new demands, providing more applications and data storage whenever you need it. Cloud security easily scales with your cloud computing services. When your needs change, the centralized nature of cloud security allows you to easily integrate new applications and other features without sacrificing your data’s safety. Cloud security can also scale during high traffic periods, providing more security when you upgrade your cloud solution and scaling down when traffic decreases.

Cloud security issues and threats

In the 2020 cloud security report, there are mixed reviews of whether cloud adoption will improve enterprises’ security. 45% of those surveyed said that both the security of cloud applications and on-premises applications are the same. 28% of respondents said that cloud apps are more secure than on-premises apps while 27% were concerned that cloud apps are less secure than on-premises apps. The same survey highlighted that 93% of respondents were extremely concentrated on public cloud security. (Source: Bitglass)

These data show that enterprises recognize that cloud adoption is inherently safe but are battling with their responsibility to use it securely.

Organizations, which influence cloud technologies without monitoring cloud security risks take a chance to open themselves up to a bunch of monetary and technical risks. We should separate the top security risks that accompany embracing cloud technologies and tips to mitigate them.

Unauthorized access: It is the biggest risk to cloud security. According to a new cloud security spotlight report, 53% of respondents see unauthorized access via improper access controls and misuse of employee credentials as their biggest cloud security threat. Unapproved access includes people getting too big of business information, organizations, endpoints, gadgets, or applications, without having legitimate permission. Fortunately, poor access control can be handled through security solutions in combination with access management policies. Indusface’s Web Application Firewall permits the blocking of access to cloud applications in light of IP, nations, GEO area, and more. It gives total tracking, monitoring as well as reporting of application access, empowering ventures to conform to information security guidelines and regulations.

Tips to prevent unauthorized access:

  • Develop a data governance framework for all user accounts. All user accounts should be connected directly to the central directory services like Active Directory that can monitor and revoke access privileges.
  • You can use third-party security tools to regularly pull lists of users, privileges, groups, and roles from cloud service environments. Then your security team can sort and analyze it.
  • You should also keep logging and event monitoring mechanisms in place to detect unauthorized changes and unusual activity.

Distributed denial of service attack(DDOS): One of the most common types of attacks on the cloud, that is very damaging. DDoS (Dispersed Disavowal of Assault) is an attack that includes denying access to online services for genuine users by flooding them with malicious connection requests.

Tips to prevent distributed denial of service attack(DDOS):

  • Have an excess of bandwidth on your enterprise’s internet connection. The more bandwidth you have, the more hackers must do to flood its connection.
  • Discover vulnerabilities in your system – scan your network and system to determine vulnerabilities with web application scanning tools to find vulnerabilities, which can be exploited to execute DDoS attacks. Implement security controls to fix the detected security issues.
  • Keep a backup internet connection – a backup connection with a separate pool of IP addresses provides an alternate path in case the primary circuit is flooded with requests.
  • Configure WAF rules to filter out the malicious IPs – Configure your WAF firewall with custom rules to monitor and filter out traffic based on your requirements.

Cloud misconfiguration: Three-quarters of all ventures on the cloud are experiencing some kind of cloud misconfiguration, which influences security. Normal shortcomings include default passwords, inadequate access limitations, mismanaged permission controls, inactive data encryption, and more. A considerable lot of these vulnerabilities result from insider dangers and an absence of security awareness.

Another way organization acquaints vulnerabilities is by endeavoring to customize its cloud use by setting changes or modules. These specially appointed changes can cause arrangement float, which makes accessibility, management, and security issues.

Tips to prevent cloud misconfiguration:

  • Get to know your Cloud- Learn all the services, settings, and permissions of your cloud services, and never forgot to leverage the benefits of integrated security features.
  • Modify credentials and permissions- thoroughly check the default credentials and set up multi-factor authentication to ensure an extra layer of security.
  • Regularly audit your cloud asset- Don’t assume that properly configured cloud settings will remain the same for a long time. Proper auditing and monitoring can help you to identify signs of misconfiguration.
  • Choose the right security solutions- The best cloud security service providers like Indusface can provide a complete package of features, which includes security management, threat detection, and intrusion prevention.

Data leaks and breaches: The biggest and most critical cloud computing threat for associations today is the leak of personal and sensitive data and information – both accidentally and purposely. The risk of information breach increases as additional organizations permits their representatives to involve individual devices for work without carrying out a strong security strategy in place.

Utilizing personal devices to get to storage services like One Drive or Dropbox gives rise to security risks, particularly when older operating system adaptations are utilized. One more way by which delicate data can be leaked is because of insider threats. Storing sensitive data and passwords in a plain text file can mean it is susceptible if the attackers get their hands on it. Especially this is a high risk in the cloud since it is a shared environment, a single vulnerability on the cloud opens the whole environment to be compromised leading to data breaches and loss.

Tips to prevent data leaks and breaches:

  • Encrypt Data- Sensitive data should not be in your cloud environment without being encrypted.
  • Change Password- Store all your passwords in a safer place. Be smarter while you choose a password and increase the frequency with which they’ve changed.
  • Set Permissions- Not all employees need the same level of access to your sensitive files. Assign permissions based on a ‘need to know’ basis to prevent the wrong people from accessing.
  • Educate your staff- Train your staff to prevent them from inadvertently leaking sensitive information.

Insecure API: The reception of APIs is favorable for organizations, however, it is a bad dream for the security group. However, APIs are intended to smooth out cloud computing processes, they are not generally black and white. There is an ill-defined situation where APIs whenever left unstable can permit programmers to take advantage of private details. Inadequate API security is one of the significant reasons for cloud information breaches. Gartner also predicts that by 2024, API abuses and related data breaches will double. For 2023, we don’t see any reason to doubt that APIs will continue to be a top target for attackers, resulting in theft, fraud, and business disruptions.

Tips to prevent insecure API:

  • Comprehensive authentication & authorization policies- APIs should be designed with tokens, signatures, quotas, encryption, API gateways, etc., to ensure API security.
  • Web Application Firewalls- applies web-based vulnerability exploit defense to APIs in the cloud
  • Choose a standard API framework- rely only on APIs that are designed with security in mind. Examine its security aspects and decide whether it is secure enough to integrate 3rd party apps.

How to choose the right CSP?

Finding the right CSP arrangement with thorough security cloud administrations is vital for your information’s assurance and your organization’s general well-being. A decent seller will know the significance of safety in cloud computing and have a couple of primary highlights to bring down risk. For instance, a vendor with thorough cloud-based security will have controls intended to prevent information leakage and back information encryption and solid authentication.

Below are six things to look for in a cloud solution and some questions to ask your CSP provider about security:
  1. Controls designed for data leakage: Look for providers that have built-in secure cloud computing controls that help prevent issues such as unauthorized access, accidental data leakage, and data theft. They should allow you to apply more precise security controls to your most sensitive and valuable data, such as through native security classifications.
  2. Strong authentication: Ensure your CSP offers solid validation measures to guarantee legitimate access to major areas of strength through controls and multifactor authentication (MFA). The CSP ought to likewise uphold MFA for both inner and outer clients and single sign-on, so clients can simply sign in once and access the apparatuses they need.
  3. Data encryption: Guarantee it’s feasible to have all information encrypted both at rest and in transit. Information is encrypted at rest utilizing a symmetric key as it is written to storage. Information is encrypted on the way across wireless or wired networks by moving over a protected channel utilizing Transport Layer Security.
  4. Continuous compliance: Look for content lifecycles management capabilities, such as document retention and disposition, eDiscovery, and legal holds. Find out if the provider’s service is independently audited and certified to meet the toughest global standards. A provider that focuses on continuous compliance can protect your company from legal troubles and ensure you’re using the most updated security practices.
  5. Visibility and threat detection: Visibility and threat detection are two critical factors to consider when choosing a CSP. A good CSP should have comprehensive visibility into the cloud infrastructure and robust threat detection mechanisms to identify and mitigate security risks effectively.
  6. Integrated Security: Integrated security is an essential point to consider when choosing a Cloud Service Provider (CSP). Integrated security refers to the ability of the CSP to provide comprehensive security features and functionalities that are tightly integrated into the cloud environment.
    • A good CSP should offer a range of integrated security features that can protect the cloud infrastructure from various types of security threats. Some examples of integrated security features that a CSP should offer include:
    • Identity and access management (IAM): This feature helps to ensure that only authorized users can access the cloud resources. IAM allows the CSP to manage user identities, control access permissions, and provide multi-factor authentication to enhance security.
    • Data encryption: Data encryption is an essential security feature that helps to protect data stored in the cloud. A good CSP should offer end-to-end encryption for data at rest and in transit.
    • Network security: Network security is crucial for protecting the cloud infrastructure from external threats. A good CSP should offer robust network security features such as firewalls, intrusion detection, and prevention, and distributed denial of service (DDoS) protection.
    • Application security: Application security features such as web application firewalls (WAFs) and vulnerability scanners can help to identify and mitigate security risks in cloud-based applications.
