Data center security involves the practices and preparation that keep a data center secure from threats, attacks, and unauthorized access. Aspects of data center security include physical security, requiring site planning to limit physical break-ins, and network security, with security engineers who can install firewalls and anti-malware programs to prevent breaches. More recently, social engineering security has become an important aspect of keeping the data center secure. This involves maintaining practices and awareness campaigns to ensure that authorized persons do not unwittingly disclose information that can be used to defeat existing security measures when interacting with unauthorized persons.
The speed of technological advancement means that security threats continue to evolve rapidly. With more virtualized data center technologies, there is an increasing need for data center security at the infrastructure layer. Security integrated within software enables a more fine-grained security approach, along with greater agility and adaptation when dealing with security threats.
