What Kind of Threats and Attacks are Risks for Cloud Platforms?

Tools that provide cloud security should handle threats and attacks that aim to compromise cloud platforms. Some security issues related to using cloud-based file management tools and security platforms are listed below.

An image featuring cloud platform threat risk concept
  • Malware: Malware attacks are a real threat to cloud applications. Unlike an architecture that relies on local servers, cloud platforms can be accessed more easily by outsiders. Cloud malware spreads quickly, and the potential damage increases as long as the threat is left undetected.
  • Cloud-based Security Tools: help segment an organization’s network so that any potential malware threat only affects a small section of the entire network.
  • Loss of Data: Data loss occurs when assets stored in the cloud can no longer be recovered. Cloud security platforms help clients regularly back up important data. A cloud-based SIEM is used to ensure that raw data has not been tampered with.
  • Data Breach: Data breaches are a top security concern for companies that use cloud infrastructure. Members of an organization must have appropriate access levels where only relevant data is available. Cloud security tools can be used to simplify this into a role-based access control system.
  • Insecure APIs: Malicious actors can take advantage of API vulnerabilities to perform DoS attacks and code injections. Some cloud security tools can scan the entire cloud environment and source code for potential vulnerabilities. A centralized cloud monitoring solution also helps keep track of which APIs are being called.
  • Distributed Denial-of-Service Attack: A Distributed Denial-of-Service (DDoS) attack is a synchronized cyberattack where a single network is targeted by multiple systems that overwhelm the network with traffic, rendering the network inaccessible to the intended users. Given the wide scope, DDoS attacks are a major risk for cloud computing environments. Organizations should use cloud security tools to set up firewalls and intrusion detection systems to protect servers from possible DDoS attempts.

How Cloud Security Tools Provide Extra Security

An image featuring cloud security tool logo concept

The top cloud security tools provide protection against threats, assist in identity management and access controls and ensure the organization follows regulatory compliance.

Cloud encryption is used to transform plain text data into an unreadable format which is then stored in the cloud. This process gives the data additional protection against unauthorized users and will protect sensitive data if a breach were to occur.

There are two main encryption methods. Symmetric encryption is generally used for bulk data. The method is symmetric since the key for both encryption and decryption is the same.

Asymmetric encryption, on the other hand, has separate keys to encode and decode data. These keys are usually called public and private authentication keys. This method ensures that the data cannot be read unless a user has both the public key and personal token.

What are the Tips to Prevent Cloud Security Threats?

The best practices to prevent cloud security threats are given below.

An image featuring preventing cloud security threats concept
  • Encryption: Encryption allows data to be kept safe in the cloud. Encryption using multiple keys allows only the right people to be able to access sensitive data. Compliance measures may also require user data to be encrypted to maintain data privacy.
  • Multi-factor Authentication: Malicious actors can use phishing methods and other techniques to try to log in to the cloud system. Multi-factor authentication allows the system to confirm a user’s identity through multiple pieces of evidence.
  • Microsegmentation: Microsegmentation involves dividing an organization’s cloud network into different smaller zones. Separating technologies will minimize damage should a breach occur.
  • Secure User Endpoints: Endpoints serve as access points to an organization’s cloud processes. These endpoints could be anything from a laptop or smartphone to an on-premise server. Endpoint security can be maintained by providing antivirus software, pop-up blocks and virtual private networks to all endpoint devices.
  • Email Gateway and URL Filtering: Companies should also set up secure email gateways to prevent suspicious emails from propagating. A URL filter can also be implemented to prevent these devices from accessing suspicious links.
