What is data security? In computer parlance, data security simply means securing digital information, including those at a server, from malicious influences and from the unprofessional or mischievous activities of unauthorized personnel, including a hacker. If your company uses servers for its network infrastructure, this can be one of the biggest threats to that network because if the servers are attacked by attackers, all the network data is at risk. The attack could be denial of service, deletion of data or corruption of files.
Data security also refers to the measures you take to protect confidential corporate information from unauthorized parties. Two common types of security measures are encryption and data masking. Encryption involves transforming unsecure data into a string of letters and numbers that can be deciphered with the help of a secret key. The secret key is provided by the company to its authorized personnel only. There is considerable expense involved, but it greatly reduces the risk of eavesdropping and captures the attention of anyone trying to eavesdrop on a confidential conversation.
Data masking, on the other hand, involves creating a false copy of an unimportant data that can be used as proof for authentication. The proof may be an encrypted email, a scanned document, or a video recording. This is the best practice for data security because it offers high-level protection against eavesdropping and hacking. However, it is not enough to prevent attacks; you should also be able to identify the breach and fix it quickly so that others can’t do the same thing.
One of the primary causes of data loss is a disaster. Natural disasters such as earthquakes, floods and fires can destroy your servers, data backup tapes and files storage folders. It is therefore important to keep copies of important documents and files in off-site locations, so that if you experience a disaster, you still have a safe place to retrieve and store your data. This is where cloud computing can help you. With a reliable hosting service and a good security process in place, your servers can be backed up to a remote location using the most modern technology.
The third top threats to data security include the unauthorized access of user accounts and systems. An unauthorized access can allow hackers to gain access to privileged systems or to simply bypass authentication. With cloud computing, these threats are eliminated because the server is physically located at a different location and controlled by the service provider. For example, Gmail has recently implemented measures that will make it harder for unauthorized access to its system by implementing two-factor authentication.
In order to secure the data resides in your computing environments, it is necessary to consider the level of access that is needed. While there are no hard and fast rules about what is needed for a given level of access, providers generally recommend that users have level of access that is not too extensive. A basic system of access includes setting up an email account with password protection and enabling a system of limited computer use. These basic security measures will help prevent unauthorized access by limiting access to sensitive data.
Encryption and decryption is another area of concern when it comes to data security. Modern technology provides strong and complex encryption algorithms to provide strong encryption and decryption. Service providers utilize these algorithms to ensure that sensitive data is transmitted through channels that are protected and cannot be intercepted. Encryption is typically used between a client and server to ensure that sensitive data does not fall into the wrong hands.
Data security is a significant issue because it affects the security of a company and the confidentiality of information stored in the company. However, data security is not just about securing information from unauthorized access. Ensuring the proper physical protection of servers and computers also falls under this topic. Proper firewalls and other protection measures can provide additional protection. All these factors play a vital role in information security but they do not fully explain the complexity of securing a network for a business.
