Module 7 Team Module Summary Discussion Case: What are you going to do about the company’s security problems?
You are the new IT manager at InvestCo, a small securities firm, and three days after you started your new job the secretary to the CEO was tricked into giving the CEO’s password over the phone to someone she thought was in the IT department. Luckily she quickly discovered that she had been tricked and had the CEO immediately change his password. When asked, the secretary said she knew the CEO’s password because it was the same one that he used for his Facebook account. You’ve been told that as far the IT staff can determine, the hacker probably did not use the stolen password before the CEO’s password was changed. However, if the thief had gotten in, he would potentially have had access to the extensive data that the company keeps on its clients. The CEO is very concerned about the potential liability and loss of customers if the client data had been stolen. Now it is your task to reexamine the firm’s policy on employee and customer account passwords, craft a new security and data retention policy, and to make a recommendation to the CEO.
InvestCo holds, trades and manages stock and bond portfolios for clients. There is an existing security and password policy that has been in place for 3 years. Some longer-term employees remember the security training that occurred back then, but there has been no training since the old policy was put in place. The password policy was strengthened two years ago so that passwords had to be longer, couldn’t be reused and had to be changed monthly. Following that change, an intern was hired to help reset passwords when employees and clients couldn’t remember their password.
Due to the financial nature of the company’s business, your recommendation must make the security of financial data paramount. But your recommendations must take usability and accessibility by employees and customers into account. A very secure but inaccessible system would be bad for business, but so would a very accessible but insecure system. So your task is to identify the problems with the existing security at InvestCo. Then craft a security policy and implementation and maintenance plan that addresses those problems while striking a balance between security and accessibility.

Question 1: Chose a password policy to present to your boss the CEO. In your recommendation be sure to address how it improves security and or accessibility. How would your recommended policy have helped the recent security breach? Identify at least one negative factor related to your recommended
Stay with the current policy but have everyone change his or her password. Send the CEO’s secretary to training on recognizing social engineering. Teach everyone how to craft better passwords
Move to an aggressive password policy where strong passwords are required, weak passwords are prohibited, and users are required to change their password frequently. Provide everyone with a password manager so that people stop hoarding passwords, passwords are compliant with the new aggressive rules, and strong passwords become disposable.
Keep the current password policy but add in multi-factor authentication for every login. The additional factors may include an RSA token or a smartphone app, as well as the potential for biometrics, and location based limitations (logins only at known locations)
Craft your own password policy. Provide details.
Question 2: In the security breach described in the first paragraph there are several types of security problems. Using the list below, identify how each item in the list shows up in the case.
Employee training problems
Employee/company operating process and procedure problems
Need for client security procedures
Need for a password policy for clients
Need for a better password policy for employees
Need for a data retention policy
Need for a data access policy
Need for Intrusion detection/prevention measures
