Employees, who have complete awareness about the lurking cyber crooks and the importance of cybersecurity, are a boon in any company, big or small. Human error may lead to vulnerabilities leading to data leaks and security breaches. So, it is essential to have specific internal policies in place with strict implementation to maintain security standards in the functioning and data handling of a company. Employees must know whom to contact in case of an emergency regarding data security and the first course of action in case of any untoward incident.

Cloud is a technology that can be used to ensure that sensitive data of the company is not stored locally on any machine in the company but stored on a cloud instead with greater security. It may burn a hole in the company’s pocket, but the investment is long term and worth it with an increasing number of data breach incidents. On the other hand, be sure to associate with cloud service providers who are reputed and provide high-quality security to the stored data. It keeps away from the prying eyes of hackers and goons ready to use even one vulnerability they come across to their advantage and carry out a data breach.

Specific rules for passwords must be set, including the minimum number of characters, the use of alphabets, numbers, special characters. Passwords must be changed after regular intervals of time, for example, once every three months to enhance security.
