Database security 101 Part 3

Potential threats to your data security
You need to protect your data and database design from both unintentional and intentional changes.

Someone might try to copy aspects of your design, look at the data entered by your users, damage the system (perhaps by using someone else’s user ID).

They might try to enter false data, ruin your reports and layouts, corrupt calculations, or break scripts. They can also write bad code, plant worms or Trojan horses, or put in malware or spyware depending on what platform or server you are using.

The most common threats to your data include:
• Unintentional threats from known parties, and accidents. Authorized users can inadvertently make mistakes, see data they shouldn’t see, delete or change records that they shouldn’t have access to, and delete or damage files so that the system becomes unavailable to the rest of the users. Or, a badly set up database, or one not granted enough licenses on a network, for example, might block others from accessing it until they log out.
• Intentional threats from known parties. Consider hackers who will benefit from accessing data that they shouldn’t see, who might falsify data, or intentionally try to damage the data maliciously in order to destroy it or mislead you.
• Uninvited intruders or threats from anonymous parties. Mostly, these are Internet-based threats from intruders with anonymous access who attempt to steal information, cause damage, or make web systems unavailable. These cybervandals and hackers can cause a great deal of damage if you don’t think about security from the outset and leave yourself vulnerable.
