Cloud Cyber Security: Risks, Architectures, and Solutions

The transition to the cloud not only represents an opportunity for companies, which can implement more “agile” tools and optimize operating costs, but has also imposed a paradigm shift in cyber security. The spread of cloud services opens the way to new threats and requires a different approach to cyber security.

The Risks

The common security threats on the cloud include:

The human factor – Beyond borderline cases in which attacks are carried out with extremely sophisticated tools or zero-day vulnerabilities that allow systems to be compromised directly, cybercriminals use techniques that exploit unpreparedness, naivety, or a moment of distraction of individuals. From phishing techniques to sending malware, the favorite target is always the human being, who represents the real weak link in the chain.

Abused privileges – The versatility of the new platforms makes it possible to create, delete or duplicate objects with impressive ease. Unfortunately, the cases in which these activities are not accompanied by adequate attention to the settings are still numerous.

Weak controls – One of the weaknesses of cloud systems is also caused by a fundamental misunderstanding regarding the necessary protection tools. A certain amount of confusion is often created about the adequacy of the cyber security tools provided by the service providers themselves, which many companies (erroneously) consider sufficient to protect the integrity of data and services.

Very often, however, the standard protection tools implemented on cloud platforms by providers are not enough to protect the end user from cyber threats.

The Required Architecture

For cloud resources to be protected against security threats, a cloud security architecture should include the following core principles:

Security in design – In cloud architecture, security controls should be implemented that are not subject to security misconfiguration.

Network security – Once an attacker has gained access to a network, segmenting the network is important to limit their ability to move laterally.

Agility – Cloud computing makes it possible to develop and deploy new solutions. This agility shouldn’t be compromised by security. Integrated into agile development lifecycles, cloud-native solutions can help organizations improve security.

Visibility – keeping visibility throughout an organization’s entire infrastructure requires both security tools and monitoring processes.

Unified management – Cloud security solutions must be managed centrally by teams from a single point of access.

Automation – Cloud environments require automation to provide and update security controls fast and efficiently.

The Solutions

  • Access Management – Access Management (systems are required by all companies, so access to information can be controlled.
  • Threat monitoring – With Threat Intelligence tools, you can identify attackers currently targeting your systems or those posing a threat in the future. An IPS tool sends a notification to the user when an attack occurs to mitigate it and give them time to act.
  • Encryption – Data encryption makes it nearly impossible for anyone else but you to decrypt the data without your decryption key.
  • Pen Tests – Testing for vulnerabilities and penetrations is also important for maintaining and improving cloud security. Using these practices, you or your cloud service provider identify any weaknesses in your cloud infrastructure that could be exploited.
  • Firewalls – Most firewall software protects against threats by filtering packets, examining their health, using proxy servers, blocking IP addresses, preventing domain names from being displayed, and blocking ports.
