Storage security is defined as a set of criteria and ambiance which makes use of storage resources that are available only to the authorized person and trusted networks and inaccessible to several other entities. These frameworks can be applied to various sorts of hardware, software, network, communications protocols, and organizational policies.
Network Security:
Several issues need to be discussed when security for a storage area network (SAN) is considered. Most importantly, a network should be easily accessed by the authorized people, corporation and agency. Also it should be difficult for a potential hacker to compromise the system. A network is expected to be reliable and stable under various contingent circumstances. Also the volume usage and its stability is to be protected against online threats such as viruses, worms, Trojans and other malicious code.
Data at Rest Security:
The data of sensitive nature should be encrypted and third party services which are of unknown nature of work and origin should be disabled for minimizing the threat level to security. The operating system (OS) should be provided by the platform vendor and needed to be updated periodically. Also physical security and access control to the data-center should be privately maintained and prior attention should be given to the regulation of the assessing authorities. Periodic changes to security credentials is one of the best practices that needs to be undertaken.
Data Storage in Motion Security:
Checking the identification and correction of the weak links in a data movement process is a well advised practice. Data-Discovery tools are helpful in analyzing and identifying the potential threats and to ensure adequate protection. Having mirrored storage copies of highly confidential data prevent data loss due to unexpected disasters and system malfunction. The principal terms and conditions to be followed in a network environment should be practiced and followed by the team members of an organisation. When you are required to move your confidential data electronically, make sure they get transferred via secured connection of public/private network. Secure transfer technique includes data encryption, virtual private networks and IPsec protocol. Also making a hacker’s time and money expenditure high for him/her in cracking a secured system will reduce the likelihood of his attack to happen. For instance, a file encrypted by AES 128 encryption method requires 3.18 x 10^16 years to get decrypted by a hacker which means the possibility for the event to happen is zero. These are the set of prerequisites to be followed for ensuring a threat free environment to our data storage and to ensure full proof security.
