The Cobbler’s kids have no…security

I had planned to enroll in my local chapter of ISSA for years but for variety of reasons(life happens) I kept putting it off. ISSA has a well deserved reputation as a great organization to mingle with security types and keep abreast of latest profession issues. Recently my travel slowed down so I thought-now or never! I went to ISSA site and navigation was great on type of membership-which local chapter and application form. At end of form I hit submission button expecting an " OK pay us now page" to pop up. But nothing happened. So I concluded they probably send email with payment instructions.A week and half went by—I had called member support number to inquire if received my application since I never got an acknowledgement that “you successfully applied” But NADA! So I tried to fill out application again assuming it never was received but results were same. So I found local chapter management who escalated my issue within 1 hour and I got email from ISSA IT asking me to describe issue(broken link?) so they could rectify it. Next I got email with PDF form to fill out and submit until web site form issue could be fixed. Talk about service!  I became excited and chastised myself for not joining this best industry association earlier.
Then came the shock! As a security guy I almost cried and fell to my knees. ISSA THE SECURITY ORGANIZATION FOR PRACTICING PROFESSIONALS -asked me to submit credit card payment information in unencrypted form. Even worst I could mail or fax form to them! So my credit card info could be received by the cleaning lady emptying the waste baskets near the fax machine. Or An ISSA employee with maxed out credit cards would have a new lease on their available credit life! I am surprised they didn’task for my SSAN!
Maybe ISSA needs to hire one of its members to do a security assessment on ISSA corporate security policies and processes. This seems to be an embarrassment to the organization AND its members. Maybe my anal retentive personality needs to “chill out!”. Am I overreacting? Is it fair to criticize Corporate ISSA’s security policies and practices when all they were trying to was was help me? I would like your opinion. Maybe it will help me seek counseling for my problem!
