Data security involves establishing security measures to guarantee the confidentiality, integrity and availability of data. Data security covers a variety of actions, ranging from encryption of files and emails to monitoring access to data and systems. It also covers the protection of physical devices that contain sensitive data, such as USB flash drives and mobile and desktop computers. Data security best practices include implementing strong passwords, limiting access to data to authorized users only, and implementing multi-factor authentication for the most sensitive data.

Companies that fail to protect the personal information of their customers will lose business. According to a recent study 75% of customers are likely to stop buying from a company in the event that they feel they don’t feel that it is a good company to protect their privacy. Businesses also face the risk of being subjected from fines and other legal consequences if they fail to not have a proper security program for data.

Many security experts don’t think encryption is sufficient to protect data from hackers despite its widespread usage. While encryption can limit the ability of a malicious attacker to exploit data that has been compromised, it does not prevent them from using stolen information to carry out fraudulent activities or to attack other networks and organisations.

The first step for businesses looking to protect their data is to create and maintain a data inventory, which categorizes the data based on its sensitivity, use situation and the need for accessibility. Then, a company can develop a security policy that defines the restrictions on who is allowed access to what data, and what consequences are for violating the policy.

Another way to safeguard your data is to keep backups either on disks, or in the cloud. Backups can be recovered in the event of data loss or hacking. Software tools, like cloning, mirroring, replication snapshots, changed block tracking are becoming more popular to offer additional layers of protection for data and recovery.

The most basic tenet of data security is to ensure only authorized users have access to the data. The simplest way to do this is by requiring authenticating users with something they know (e.g., passwords) or with something they have (e.g. or a security token or biometrics) or both. This is referred to as multi-factor authentication and is a crucial component of any data security strategy.

It is also essential to upgrade all your software regularly to fix vulnerabilities and improve data security. This will not only help keep your computer system running smoothly, but also assist in protecting your data from cyberattacks.

Data breaches can be catastrophic for clients and businesses. Criminals are able to use personal data to commit identity theft or blackmail. This can have devastating consequences for individuals and their families. Data breaches can be costly for businesses as well because they are usually in the spotlight and are subject to the possibility of public embarrassment.
