The team must have documented procedures for preventing, detecting and handling incidents that may occur, the documentation should not be a foreign article to any person who is on this team. This team must also be provided with articles that keep them up to date with the latest cyber-security threats and trends.
  2. If you are in an organization that frequently hires interns and contractual staff, be sure to always CREATE TEMPORARY ACCOUNTS for these individuals, which expire according to the employee’s contractual agreement. You can always extend the expiry date if required.
  3. Make sure there are no UNUSED ACCOUNTS on your network, that can be exploited, a simple DSQUERY command on a Windows Active Domain Controller will do the trick to search for accounts that have not been used in a specifies time frame.

MAKE SURE THAT THE ACCOUNTS OF STAFF THAT HAVE LEFT ARE TERMINATED OR DISABLES AS SOON AS POSSIBLE, from when the individual leaves the organization. It is best practice for IT to informed in advance of when an employee’s contract is about to terminated.
  5. If possible, you should try and identify DISGRUNTLED STAFF MEMBERS to either monitor or limit their access. Some employees fueled by vengeance could be encouraged to steal and sell data to your organizations competitors. In the event where the employee’s unhappiness can be alleviated it would be prudent to try and do so, for the sake of improving the situation.
  6. Often described by “something you have and something you know”, TWO-FACTOR AUTHENTICATION is another step you can take to improve network security.

If the individual has the password but not the OTP or security token they will be blocked at the gate.

Make sure you use the right technology for the type of data that needs to be encrypted, ensuring that if someone steals a hard drive or is capturing traffic they will not be able to get to the data involved.

  9. In taking into account the above suggestions do not forget to GUARD YOUR PERIMETER. IT security is a complex subject for many organizations with a-lot of moving parts, you don’t only need to guard against internal risk but it is imperative that you focus your security initiative energy on all external-facing devices as well.
  10. It Security can be a very expensive exercise so it is important to NOT SEE IT AS INSURANCE, other wise the temptation to remove it will be very high especially when times are tough and budget cuts need to occur. IT security is an investment, like you need to invest in the police, because when you need them they must be there.
