Is my data safe? And Is my data protected?
Let’s learn more about what cloud security is, how it works, and the key types of cloud security. The importance of cloud security, and its key benefits, risks & threats.
What is cloud computing?
Cloud computing is the provision of various services over the Internet. These services include tools and applications such as computers, servers, databases, networks, and application software. Cloud storage allows you to store data in a remote database. As long as the electronic device has access to the web. It has access to the data and software programs to run it. Cloud computing is gaining importance for many reasons like cost savings, improved productivity, performance, security, and efficiency.
What is cloud security?
Cloud security, also known as cloud computing security, is the protection of digital assets and data stored in the cloud from theft, leakage, and deletion. Measures to protect this data include, but are not limited to, two-factor authorization (2FA), VPN usage, security tokens, data encryption, and firewall services. Organizations need cloud security as they implement their digital transformation strategy. And integrate cloud tools and services as part of their infrastructure.
Why is cloud security important?
As companies continue to migrate to the cloud, understanding the security requirements for secure storage becomes essential. In general, most cloud providers follow best security practices and take proactive steps to protect the integrity of their servers. However, organizations must also verify and make sure that they are implementing sufficient measures when protecting data, applications, and workloads running in the cloud. Whether your organization operates in a public, private, or hybrid cloud environment, cloud security solutions and best practices are essential to business continuity. Securing cloud computing data is just as important as securing data for your local systems
For companies moving to the cloud, strong cloud security is essential. Security threats are constantly evolving and improving, and cloud computing is less risky than an on-premise environment. For this reason, it is important to work with a cloud provider that offers the best security for your infrastructure.
What are the benefits of cloud security?
Organizations are realizing the many business benefits of migrating their systems to the cloud. Cloud computing enables organizations to scale, reduce technology costs, and leverage agile systems. However, it is important that organizations have full confidence in their cloud computing security. All data, systems, and applications are protected against data theft, leakage, damage, and deletion.
Cloud security offers several benefits, including:
- Centralized protection: Cloud-based corporate networks consist of multiple devices and endpoints that can be difficult to manage when working with service providers. Managing these central entities improves web traffic analysis and filtering, streamlines network event monitoring, and results in minor software and policy updates. Disaster recovery plans can also be implemented and resolved quickly.
- Cost reduction: One of the benefits of using cloud storage and security is that there is no need to invest in dedicated hardware. This will reduce not only capital expenditures but also administrative overheads. Cloud security provides proactive security features that provide protection 24 * 7 with little or no human intervention.
- Reliability: Cloud computing services offer the highest reliability. With the right cloud security measures, users can securely access data and applications within the cloud, no matter where they are or what devices they use.
What are the challenges of cloud security?
All cloud models are easily vulnerable to threats. IT departments have been warned by nature to move critical systems to the cloud. Whether you have a public cloud, private or hybrid environment. Cloud security offers all the tools of traditional IT security, enabling businesses to take advantage of benefits of cloud computing. This helps in staying secure, while also ensuring that privacy and compliance requirements are met.
Cloud technology has many technological challenges in various aspects of data management and storage.
Some of the challenges are as follows:
- Infiltration / data breach
- Incorrect configuration and incorrect change control
- Inadequate Cloud Security Structure
- Insufficient access, log-in details, identity, and key management
- Phishing attacks on internal employees
- Bad security interfaces and APIs
- Denial of Service (DOS) threats in the cloud computing environment
What types of cloud security solutions are available?
Identity and Access Management (IAM) Identity and access management (IAM) tools and services enable companies to implement policy enforcement protocols for all users. IAM enables the creation of the digital identity of all users. It actively monitors and prevents interactions with the data
- Data loss prevention (DLP) Data Loss Prevention (DLP) offers tools and services to safeguard the security of cloud data. These tools use remediation alerts, data encryption, and other precautions to protect all stored data.
- Information Security and Incident Management (SIEM) – SIEM provides comprehensive security solutions that automate surveillance, analysis, and threat response in the environment. SIEM technology uses artificial intelligence (AI) technology to associate logged data across various platforms. It enables IT, teams, to successfully adapt their network security practices while responding quickly to any potential threat.
- Business continuity and disaster recovery Despite the precautionary measures that organizations take for their local and cloud infrastructure, data corruption, and disruptive losses can still occur. Businesses must be able to respond as quickly as possible to newly discovered vulnerabilities or significant systemic losses. Disaster recovery solutions are one of the best cloud security solutions that provide organizations with the tools, services, and protocols they need to help recover lost data and maintain normal business operations.
How does cloud security work?
There are various technologies, policies, and processes that a cloud provider must use to ensure the security of cloud data. When considering which cloud providers to use, consider only those who base their security policies and procedures on international security standards, such as ISO 27001 and the National Institute of Standards and Technology (NIST). Also, confirm if the CSP follows the requirements of applicable local regulatory authorities such as the General Data Protection Regulation (GDPR) and HIPAA in Europe.
How to select a cloud service provider (CSP)?
Your cloud data security will depend on the specific cloud provider, as well as the cloud security solutions available. However, the implementation of processes should be a shared responsibility of the business owner and the solution provider (CSP).
Here are the practices that your organization should look for with a cloud service provider:
- File encryption: Data must be encrypted using standards like AES-256 encryption. Only authorized users should have access to it. Even the cloud service provider should not be able to see your data because the data is stored in encrypted cloud storage.
- Secure communication: All the data must be encrypted using SSL encryption this ensures that at all times during the day, your data is safe.
- Web firewall: CSP should use a cloud Firewall, which protects against SQL injection, cross-site scripting, unauthorized source access, remote file inclusion, and other web security threats.
- Data center security and availability: The data center should be physically secured with various kinds of safety features to protect the premises and the equipment. The data center should have 24×7 security personnel, video surveillance, and biometric access. The infrastructure must maintain a redundant/duplicate infrastructure to minimize downtime and failure of IT equipment. One example could be, having a redundant power supply source in case of a power outage.
- Regular data backups: CSP should have a process in place to back up data regularly to protect your data in the event of a major failure. The most common backup types should be at least a full backup, incremental backup, and differential backup.
Preparing your business for future success begins with moving local hardware to the cloud for your computing needs. The cloud gives you access to more applications, improves data access, helps your team collaborate more effectively, and provides easier content management. Some people may have reservations about moving to cloud due to security issues. But a trusted cloud service provider (CSP) can calm your mind and keep your data safe with a secure cloud service.
