4 Top Cloud Security Threats

Cloud security threats are any possible harm that can be done to your cloud systems. When you actively defend cloud assets, you’re protecting them from unintentional or intentional threats that use weaknesses to destroy or steal data. The focus of threat management is mitigating these dangers in order to protect cloud assets effectively. Some of the biggest threats in cloud security are DDoS attacks, cloud storage buckets malware, insider threats, and APT attacks.

Distributed Denial of Service (DDoS) Attacks

DDoS attacks flood cloud services with excessive traffic, rendering them inaccessible to users. They overwhelm networks or applications with more connections than they can handle, resulting in major disruptions and financial losses. DDoS attacks use several infected devices across multiple networks to establish a botnet. This botnet is a collection of malware-infected machines that coordinate the attack.

Apply the following strategies to mitigate DDoS attacks:

• Select a good cloud-based hosting: Choose a provider with large bandwidth and content delivery networks (CDN). Hide the origin web server’s IP and restrict access with a firewall.
• Monitor infrastructure continuously: Check system capacity, traffic, and essential infrastructure, such as firewalls, on a regular basis to discover irregularities.
• Apply network segmentation: Separate internal and external networks and isolate essential systems to mitigate the impact of assaults.

Explore our list of the best cloud security companies and vendors to compare the solutions that could help you mitigate insider threats.

Advanced Persistent Threats (APT) Attacks

An advanced persistent threat (APT) is an extended and focused cyber attack in which an intruder gains access to a network while remaining unnoticed. APTs seek to steal critical information and retain long-term access. They’re painstakingly planned and frequently carried out by well-funded groups, who use methods such as spear phishing, zero-day exploits, watering hole attacks, and credential theft to breach high-profile targets.

Try these to prevent APT attacks:

• Patch vulnerabilities immediately: Keep the software up to date by applying patches as soon as possible and executing regular vulnerability scans to identify and fix vulnerabilities before they’re exploited.
• Conduct user awareness training: Incorporate a focused training program into onboarding and workflow process so employees can learn about social engineering strategies, phishing risks, and cloud security best practices.
• Monitor and develop an incident response plan: Employ continuous monitoring to spot suspicious behaviors early on and create a strong incident response strategy to resolve security breaches quickly.

4 Top Cloud Security Risks

A cloud security risk is a combination of the possibility of a threat arising and the system’s vulnerability. Cloud risks include insecure APIs, misconfigurations, cloud concentration, and unmanaged attack surface. Though completely eliminating risks is almost impossible, they can be controlled to remain within a company’s tolerance level through assessments, regulations, and developing plans for the consequences of a threat.

Insecure APIs

Insecure application programming interface (API) in cloud services allows unauthorized access and data breaches. APIs offer seamless integration between cloud services, but if not properly secured, they become points of access for attackers. API security risks may cause weak authentication, input validation, encryption, permissions, error handling, and rate limit issues.

Address insecure APIs through these practices:

• Implement comprehensive security measures: Deploy rigorous authentication, authorization, input validation, and API security testing and monitoring on a continual basis.
• Perform regular security tests and audits on APIs: Quickly detect and address problems using techniques like penetration testing, code reviews, and vulnerability assessments.

Cloud Services Misconfiguration

Misconfiguration of cloud services happens when cloud configurations are incorrect, resulting in security breaches and unauthorized access to critical data. It’s a common source of data breaches, which are frequently caused by configuration problems. This exposes sensitive information to the public internet, resulting in reputational damage and financial loss.

To lessen your cloud services misconfiguration risks, implement the following:

• Apply strict access controls and encryption: Employ stringent access control and encryption mechanisms to protect sensitive data from unwanted access.
• Conduct regular audits and ongoing monitoring: Discover and correct misconfigurations using auditing and monitoring solutions.
• Automate security setups: Use automation tools to provide consistent and safe setups across cloud services and lower the risk of human error and misconfiguration.

Delve into our complete guide on cloud configuration management to better understand how it can address misconfiguration in the cloud.

Cloud Concentration Risks

Cloud concentration risk occurs when a company relies excessively on a few key cloud suppliers. This dependence raises the possible disruptions caused by a single provider’s failure. With few options, enterprises confront difficulties in reducing this risk while reaping cloud benefits. Potential effects include widespread event impact, high vendor dependence, which limits technological options, and regulatory compliance failures due to varying restrictions.

These strategies can address your cloud concentration risks:

• Diversify cloud providers: Reduce dependency by distributing risk among several cloud providers and minimize the impact of any single provider’s failure.
• Implement multi-cloud strategies: Distribute workloads and services over multiple cloud platforms to ensure redundancy and resilience to disruptions.
• Develop contingency plans: Create carefully planned continuity plans to quickly address large cloud service outages.

Weak Attack Surface Management

Weak attack surface management occurs when vulnerabilities in a system aren’t detected and mitigated properly. It results from a failure to identify, test, and monitor potential access points, such as devices, users, and software flaws. Impacts include increased risk of data breaches, unauthorized access, and cyberattacks as a result of undetected vulnerabilities, which endanger system integrity, privacy, and the overall security posture.

Resolve weak attack surface management through these tips:

• Adopt zero-trust policies: Limit illegal access by adopting zero-trust security, which ensures that only authorized users can access networks. This lowers entry sites, strengthening the infrastructure against cyber assaults.
• Streamline networks and tools: Remove unnecessary software, program, and equipment, minimize errors, and reduce the attack surface to prevent unauthorized access to your organization’s data.
• Conduct vulnerability scans: Run regular network scans to detect and repair any vulnerabilities, ensuring visibility of the attack surface and protecting both cloud and on-premises networks from exploitation.
