In IaaS, data leakage, network infiltration, and DDoS attacks are all key security concerns.

Implementing strong access controls, regularly patching and updating software, and using encryption for data at rest and in transit are all best practices for securing IaaS resources.

Man-in-the-middle (MitM) attacks are a common attack vector in IaaS environments, where an attacker intercepts communication between two parties and impersonates one of them.

Firewalls, intrusion detection systems (IDSs), and virtual private networks (VPNs) are all types of security controls that can be used to protect IaaS resources from unauthorized access.

Implementing role-based access control (RBAC), using security groups to isolate resources, and regularly monitoring and auditing security logs are all best practices for managing security in a multi-tenant IaaS environment.

Penetration testing, vulnerability scanning, and risk assessment are all types of security assessments that can be used to identify vulnerabilities in an IaaS environment.

Using a DDoS mitigation service, implementing rate limiting, and using a web application firewall (WAF) are all best practices for securing IaaS resources against DDoS attacks.

Data loss prevention (DLP), encryption, and tokenization are all types of security controls that can be used to protect IaaS resources from data leakage.

Implementing a consistent security policy across all environments, using a single security management tool to manage security across all environments, and regularly monitoring and auditing security logs from all environments are all best practices for managing security in a hybrid cloud environment.

Security audits, risk assessments, and compliance assessments are all types of security assessments that can be used to evaluate the overall security posture of an IaaS environment.

Implementing network segmentation, using a firewall, and implementing intrusion detection and prevention systems (IDS/IPS) are all best practices for securing IaaS resources against network infiltration attacks.

User awareness training, email filtering, and multi-factor authentication (MFA) are all types of security controls that can be used to protect IaaS resources from phishing attacks.

Implementing a consistent security policy across all clouds, using a single security management tool to manage security across all clouds, and regularly monitoring and auditing security logs from all clouds are all best practices for managing security in a multi-cloud environment.

A configuration audit is a type of security assessment that can be used to identify misconfigurations in an IaaS environment.

Implementing strong access controls, regularly backing up data, and using anti-malware software are all best practices for securing IaaS resources against ransomware attacks.
