Almost all of today’s industry is based on data centers on the backbone of almost every industry, from finance, healthcare, e-commerce, and telecommunications. Because of the massive amounts of sensitive data and critical infrastructure housed in data centers, never has data center security been more critical. In this blog we will discuss the different components of data center security, what type of threats are faced by data centers and how to keep them secure.

What is Data Center Security?

Data center security is the practice, tool and protocol of protecting the hardware, software, and data residing within the data center. It includes a variety of physical security precautions like CCTV and access controls, and network security things like firewalls and encryption. A good data center security strategy will secure the data and prohibit unauthorised access, breaches and service downtime.

Data breach can cost your company a lot — financial loss, damaging reputation and even be subject to law suits. Because data centers are critical to the organization, data center security is very important and organizations ...
... that want to do business with them will want to protect its data asset, maintain customers' trust and the data center continues to provide a seamless operation.

Data Center Security – Importance.

But data centers store such important data as personal customer details, financial records, intellectual property — so they are prime targets for cyberattacks. All of which may result in compromising of sensitive data: unauthorized access, physical threats and network attacks. As the number of cyber threats grows at an incredible pace, organizations are throwing money into building multi-layered security systems to keep their data centers protected.

Organizations in finance, healthcare, and government also need to strictly follow regulatory conditions. In this context, these regulations, for example HIPAA in health care as well as GDPR for the data privacy, need very strict data center security measures to guarantee a proper security over customer data and compliance.

Data Center Security Key Elements

A comprehensive data center security strategy includes both physical and digital security measures:

Physical Security: Securing the premises and securing the employees starts physical protection. Surveillance cameras, biometric authentication, and the like are often used in data centres along with such people as security personnel (as means to control access). Furthermore, facility design elements including fire suppression system and flood detection strive to mitigate environmental aggressors.

Network Security: On the digital front, firewalls, intrusion detection systems (IDS), and encryption are all areas of data center security. The main focus of network security is to keep the data hidden while it is transmitted over a network and unauthorized access to the systems.

Access Control: Restricting access to important systems means that only the authorized personnel allowed in sensitive area. Role based access control (RBAC) and multi factor authentication (MFA) are best practices you find very common in data center security to add extra layer of verification.

Monitoring and Auditing: This allows data center managers to monitor data center activities in real time in order to detect the unusual activities. By running continuous auditing it ensures that all the security measures taken up to protect the data center are in existence.

Data Centre Security – Best Practices

Adopting best practices in data center security can help organizations stay ahead of emerging threats:

Implementing Zero Trust Architecture: In Zero Trust, by default no user or device is expected to be trusted even if it's inside the network. For security configuration, all users must be authenticated, authorized and continuously validated.

Encryption and Data Masking: Data masking makes sensitive data useless by protecting them from the access of unauthorized persons, but encryption protects them from the eyes whenever they are on transmission and storage.

Regular Security Assessments: The regular risk assessment and vulnerability test can help you look for and fix the loopholes of data center security protocol.

Employee Training: Even the safest security system is only as safe as the personnel that operate it. Training employees on data center security training on the protocols and practises that promote security ensures they know what to do to keep security.

Today’s digital economy depends on data centers that keep their infrastructure fully operational. The security of sensitive data should not only to protect, but should ensure robust security to keep customers trust and meet regulatory requirement. With data center security evolving rapidly and without end, companies can mitigate risk through a multi-layered approach to data center security that includes: physical security, network security, and access controls. The more our world progresses with technology, the more our obligation to protect the critical infrastructure data center provide.
