What are Cloud Security Solutions?
Cloud security solutions are tools and utilities you can use to secure workloads, applications, and data in the cloud. These solutions can be used in public or private clouds and often have features for hybrid or multi cloud deployments.
These solutions come in a variety of formats depending on the level of management and coverage you need. The three main formats are:
- Cloud workload protection platforms (CWPPs)—collections of security technologies that focus on security issues related to cloud architectures. These solutions typically provide features for monitoring, control, and auditing.
- Cloud access security brokers (CASBs)—software suites that mediate between cloud services and users. These solutions provide features for monitoring and filtering traffic, authenticating and authorizing users, and securing connections.
- Software as a service (SaaS)—cloud-based solutions that you can use to perform security tasks. Typically, these solutions focus on specific security aspects and integrate with other solutions to contribute to system-wide protections.

Must Have Cloud Security Solution Features
When evaluating security solutions, there are several features that you should prioritize. If solutions do not offer these features, you may want to look for alternatives. You might also consider solutions that specialize in one aspect and integrate well with your existing solutions.
Next-Gen Firewalls (NGFW)
Next-gen firewalls are firewalls that can inspect packets, provide intrusion prevention, and integrate threat intelligence. These tools provide more than the limited protocol or port inspection and filtering that traditional firewalls can.
NGFWs can detect threats that would bypass traditional firewalls because of the above features. When layered with other protections, these tools can help you identify threats before they enter your network and can prevent data leakage from the inside.
Intrusion Detection Systems (IDS) with Event Logging
IDS tools enable you to monitor your networks and systems for policy violations or suspicious activity. These tools use event and activity logging to create auditable tracks of user activity. When suspicious activity is identified, security teams are alerted. Some tools can also apply log information to protect against threats, such as suspicious IP addresses automatically.
Internal firewalls can provide an additional layer of protection for attacks that make it inside your networks or systems. These tools specifically filter and monitor traffic for individual services, resources, or segments of your network. For example, you can apply internal firewalls to protecting storage of confidential data.
At-rest encryption ensures that even if attackers can access your storage resources, they cannot use the data or understand its contents. At-rest encryption discourages theft and can grant additional response time to theft victims. For example, if encrypted passwords are stolen, users can hopefully change their passwords before attackers can break the encryption.
Native Integration Into Cloud Management and Security Systems
The shared responsibility models implemented by cloud vendors typically mean that you do not have full access to security controls or data. To gain access to the data relevant to your environments, you need to be able to integrate native solutions with any external tools you’re using. For example, you should be able to either export data to native solutions or import data from native utilities for comprehensive analysis and application.
Threat Intelligence Feeds
Threat intelligence feeds can supply you with information about the nature of threats, the techniques and tools that attackers are using, and how to protect systems against threats. Solutions should be able to ingest these feeds and apply gained intelligence automatically.

Cloud Security Threats
Failures in data security can have a significant impact on operations. Data breaches or abuses can lead to sizable compliance fines and loss of productivity, customer trust, and revenue. Because of these damages, it’s important to prioritize data security in your operations and take proactive measures to prevent security threats.
In this article you’ll learn what data security threats exist, how to distinguish between malicious and non-malicious user behavior, and how you can ensure data security with Cloud Secure by NetApp.
