The biggest security issues for any company is always going to be the employees and employee habits. Providing employees with training on how to improve their security habits to prevent unauthorised persons entering a business should be the highest priority.

If your business has sensitive information that needs to be protected, or expensive goods that need to be secured away from random opportunists looking for an easy steal, then providing your employees with training to improve their habits is key.

Many employees see somebody walking in behind them, or coming into a building and assume the other person works there, or has access and holds the door open for them. This however is a serious flaw and a bad habit, as if they don’t know that person directly then that assumption may cost a company money and even the loss of that employees job as a result of a theft or unauthorised entry of unknown persons.

If entry to a business premises is controlled and access is granted to those who have a code, keyfob, biometrics, or finger print access then opening the door for anybody, even if you know them is a bad habit that should be stamped out; lets say an employee was sacked the day before, and came back in as normal the next day to steal or break something for revenge on the company and an employee who knew them let them in, this would be bad for both the company and the employee and also the vengeful employee if they were caught.

So rule of thumb: Employees should not hold the door open to others if there is secured entry. If there is a keypad they should shield the code entered from view and not share with anybody. Opening outside fire-doors and wedging them open to let cool air in, or open so an employee can return after a cigarette break should also be stamped out.
