IV. SECURITY THREATS IN CLOUD COMPUTING

Apart from the advantages that cloud computing offers, there exist numerous security threats that preclude consumers from enchanting these advantages. In this section, those security threats are defined which have been agreed upon and generally accepted.  Data Loss can occur in various ways apart from malicious attacks .Data Breaches refer to leakage of sensitive information to unauthorized users .Account or Service Hijacking occurs if an attacker gains access to login credentials, then the compromised account becomes a launching base and attacker can eavesdrop on the consumer businesses, refund false info, manipulate data and can reply to sessions and redirect the consumer to illegitimate sites and can launch various attacks .Insecure Interfaces and APIs refer to Application Programming Interfaces which are standards and protocols that consumers use to connect with cloud services .Malicious Insiders can be trusted people within an organization who can access organizational confidential assets.

Abusive Use of Cloud Services can be described as consumer’s unethical and illegal actions to misuse the services .There are other threats which are not explained above because of being less severe but exist in the cloud environment are; Loss of Governance, Acquisitions of the cloud provider, Threats to trust, Isolation Failure, Data Segregation, Compromised Servers and Regulatory compliance etc.

Mitigation strategies in cloud computing security are actions and measures taken beforehand to lessen or remove the influence of possible threats and vulnerabilities on cloud systems. These tactics are essential for ensuring the privacy, security, and accessibility of data and services stored in the cloud. Mitigation includes utilizing technical controls, policies, procedures, and best practices to reduce risks and maintain a secure computing environment. Encryption is a crucial precaution in cloud security. It includes transforming confidential information into ciphertext using cryptographic algorithms, rendering it unintelligible to unauthorized individuals. Data is protected from interception and unauthorized access through encryption, which is used for both data storage and data transmission. Implementing effective key management practices is crucial for maintaining the security and confidentiality of encryption keys. Regular security audits, vulnerability assessments, and penetration testing are other techniques employed to discover and fix security weaknesses in cloud settings. Engaging in these tasks assists in identifying and fixing possible weaknesses, misconfigurations, and vulnerabilities that attackers may take advantage of. Continuous monitoring and integration of threat intelligence are essential for mitigation as they offer immediate insight into security events and new threats, enabling organizations to quickly and efficiently address security incidents.

A. Cloud Computing: Security Attacks

The following section defines the attacks on cloud computing security with their mitigation techniques that can be adapted to handle these attacks. Structured Query Language (SQL) Injection Attacks - In standard SQL code, the attacker inserts malicious code to access unauthorized database to gain sensitive data about the user. Man in the Middle Attacks (MITM) - When an attacker attempts to intrude in an ongoing conversation with the aim to inject false information to access sensitive information being shared then it is known as MITM attack. Domain Name Server (DNS) Attacks- In many scenarios the user access a server by calling its domain name and instead of the domain he requests for being routed to some other malicious code. It happens in the case of DNS attacks where the attacker makes use of DNS to translate the domain name into an IP address to access user’s confidential data. DNS attacks can be eradicated using DNS security measures. Cross Site Scripting (XSS) Attacks - The attacker inserts malicious code into the user’s web page to redirect him to the attacker’s website to access sensitive data. It can be done in two ways by either using Stored XSS (permanently stores malicious code into a resource managed by the web application) or Reflected XSS (immediately reflects back malicious code to the user and hence do not store it permanently). Phishing Attacks- The attacker makes use of cloud service in phishing attacks, where the attacker manipulates a web link to redirect the user to a false link and so by hijacking users account gains access to sensitive data. Mitigation tactics in the field of cloud computing security attacks involve pre-emptive actions to reduce the consequences and avoid the repetition of different cyber threats directed at cloud-based systems. These strategies aim to improve the overall security of cloud environments and protect important data and resources from cyber threats. Efforts to reduce typically involve a mix of technical controls, policy implementations, and security best practices.
