Data center security is the set of policies, precautions and practices adopted at a data center to avoid unauthorized access and manipulation of its resources. [1] The data center houses the enterprise applications and data, hence why providing a proper security system is critical.
Cloud computing offers many benefits, but is vulnerable to threats. [60] As cloud computing uses increase, it is likely that more criminals find new ways to exploit system vulnerabilities. Many underlying challenges and risks in cloud computing increase the threat of data compromise.
Traditional threats include: network eavesdropping, illegal invasion, and denial of service attacks, but also specific cloud computing threats, such as side channel attacks, virtualization vulnerabilities, and abuse of cloud services. In order to mitigate these threats security controls often rely on monitoring the three areas of the CIA triad.
The STRIDE was initially created as part of the process of threat modeling. STRIDE is a model of threats, used to help reason and find threats to a system. It is used in conjunction with a model of the target system that can be constructed in parallel. This includes a full breakdown of processes, data stores, data flows, and trust boundaries. [5]
Information assurance (IA) is the practice of assuring information and managing risks related to the use, processing, storage, and transmission of information. Information assurance includes protection of the integrity, availability, authenticity, non-repudiation and confidentiality of user data. [1]
Cloud bursting is an application deployment model in which an application runs in a private cloud or data center and "bursts" to a public cloud when the demand for computing capacity increases. A primary advantage of cloud bursting and a hybrid cloud model is that an organization pays for extra compute resources only when they are needed. [ 68 ]
Countermeasures are included in the form of actionable tasks for developers that can be tracked and managed across the SDLC. [23] OWASP Threat Dragon is a modeling tool used to create threat model diagrams as part of a secure development lifecycle. Threat Dragon follows the values and principles of the threat modeling manifesto.
The typical purpose of a virus is to take over a computer to steal data. Computer worms are programs that can replicate themselves throughout a computer network. Ransomware is a type of malware that restricts access to the computer system that it infects, and demands a ransom in order for the restriction to be removed.
