Cloud security can seem like a very complicated issue to those who are not in the IT field, and it may even seem like a very expensive “investment” at first. However, it is very important to understand that the cloud has become an asset in companies, regardless of market segment. This is because the increasing wave of digital transformation, both here in Brazil and in the world, is allowing hackers to find vulnerabilities and security flaws, allowing system intrusions to occur, and thus, information and data being hacked and stolen from businesses.
But what is security in the cloud and how to ensure that corporate businesses do not go through the pain of invading the system with loss or hijacking of valuable data and information that threaten internal operations and the privacy of the organization itself and end customers?
What is Cloud Security (or Cloud Security)?
Cloud security consists of a union of protocols and best practices in order to ensure that all services and data stored in cloud computing are protected from attacks and attacks, malicious or hackers that compromise business integrity and confidentiality. Medium Enterprises (SME’s).
The cloud is hosted on servers with internet connections that should always be available, which is usually the responsibility of third party companies that specialize in strong cloud security. According to information from the Check Point website, the categories that make up a robust cloud security service are:
Precise policy-based authentication and IAM (Identity Access Management) controls in complex infrastructures:
o At this level, work should be done with groups and roles rather than at the individual IAM level. identity and access management To facilitate the updating of IAM definitions as business requirements change. Grant only the minimum privileges to access the assets and APIs necessary for a group or role to perform its tasks. The wider the privileges, the higher the levels of authentication. And don’t neglect good IAM hygiene by enforcing strong password policies, permission time limits, and more.
Trust-free cloud security controls over logically isolated networks and fine parts:
o You must, at this point, use business-critical resources and applications in logically isolated sections of the provider’s cloud network, such as Virtual Private Clouds or vNET. Use subnetting to segment workloads between each other, with precise security policies across subnet gateways. Use custom WAN links in hybrid architectures and user-defined static routing configurations to allocate access to virtual machines, virtual networks, gateways, and public IP addresses.
Enforce policies and processes to secure virtual servers, such as managing changes and software updates:
o Cloud security vendors provide robust management of the security situation in the cloud, continually enforce governance and compliance rules and models when provisioning virtual servers, review configuration anomalies, and automatically make corrections where possible.
Protect all applications (especially distributed cloud-native applications) with an advanced web application firewall:
o This will accurately scan and monitor traffic in and out of web application servers, automatically update WAF rules in response to changes in traffic behavior, and will be deployed near microservices running workloads.
Greater data protection:
o Enhanced data protection with encryption at all transport layers, secure file sharing and communications, ongoing compliance risk management, and maintaining good hygiene for data storage resources, such as detecting incorrectly configured buckets and terminating orphaned resources.
Threat Intelligence that detects and addresses known and unknown threats in real time:
o Third-party cloud security providers add context to large and diverse streams of native cloud logs through intelligent assignment of log data aggregated with internal data such as asset and configuration management systems, vulnerability scanners, etc. and external data such as general threat intelligence feeds, geolocation databases, etc. It also provides tools that help visualize and inquire about the threat landscape and promote faster incident response times. AI-based anomaly detection algorithms are applied to detect unknown threats, which are then subjected to forensic analysis to determine their risk profile.
Real-time alerts about intrusions and policy violations shorten resolution times and sometimes even trigger automated resolution workflows.
Most importantly, security is directly related to access: insecure APIs, poor management of identities and credentials, and malicious internal user and account hacking are all threats to the system and business data.
To prevent unauthorized access to the cloud, a data-centric approach is needed, through encryption, strengthening the information access authorization process, and of course creating security and requiring passwords at all levels of access, both internal and external.
This is why security in the cloud does not depend solely on the software and security protocols themselves: to ensure that your company’s cloud is always within established security standards, internal employees must also follow protocols, instruct them to use strong passwords and adopt best practices across all operations and levels access to the system that they may have.
What are the best security practices in the cloud?
Information from the website of Huawei (a multinational company of equipment and solutions for networking and telecommunications) indicates that the modern security architecture includes four main pillars that define the minimum requirements for companies to safely migrate their workloads to the cloud:
data isolation: Prevents unauthorized access and manipulation of customer data, reducing the risk of leakage
Data encryption: Protects data and static data during transmission. We also use encrypted transmission channels to ensure the confidentiality and integrity of data.
Data redundancy: The redundant design effectively prevents data loss. These redundancy and validation mechanisms are used to quickly detect and restore any potentially corrupted data.
Privacy Protection: Providing privacy protection functions greatly improves customer confidence in you and increases product competitiveness
What are the benefits of cloud security?
In addition to allowing better internal and external results in the entire production process of the company, Cloud Security is very important for business because it is practical and fast from the moment the service is implemented to the implementation of all tasks and procedures, in addition to being scalable, that is, it allows automating self-repair processes to reduce manual tasks and improve manpower.
with security in Cloud It is also possible to establish automation of controls to prevent and disrupt security incidents (accidental or intentional), in a way that does not interfere or hamper business operations, operational teams or services provided.
