Blog 13: Cybersecurity

You are employed by a large, multinational corporation, and your responsibility is to protect your companies network, intellectual data, customer data, and computer systems from attack. We’ve spent time in class discussing many different topics related to cybersecurity, but now is your chance to use that knowledge. Tell us how you would go about defending your company from malicious users.

What protections would you put in place?
How would you store your data?
Would you hire teams to do white-hat hacking or penetration testing? What would you want them to look for?
How would you train your employees to spot malicious behavior?
How would you protect against social engineering and other physical means of attack?
If someone attacked you, would you retaliate? Do you feel it is ethical/legal to do so?
