I want to minimize PII (personally identifying information) online. However, as one with little work experience, I also want to maintain a public profile (e.g. LinkedIn) with information to help with getting jobs. My area of work is Information Security, namely Penetration Testing (aka pentesting) and Threat Hunting.
Even in general conversations, I try to minimize talking about my background, only discussing subjects of interests in work and studies. I usually don't even say where I'm from or past education and profiles. I just prefer to remain unknown, working behind the scenes, with minimal personal information available to the public.
I do put my contacts in applications forms, CVs and resumes. However, the only things I've put on my LinkedIn profile are an email address made specifically for business (not with my real name) and a brief education and work history. (Even just letting people know roughly where I'm from the schools and companies makes me kinda uncomfortable with it.)
If possible, I'd like to use an alias that I'm also using to interact with people online. I generally don't use my real name online, and I generally don't post anything personally identifiable. Most of my online activities is tied to my alias (online name) but I always submit my real name and personal information in formal documents and forms.
What's an acceptable level of anonymity for my online profile for getting jobs (LinkedIn)? Would it be a good idea to use an alias for my profile, only linking to said profile in formal documents? (e.g. real name "John Doe" in my CV but my online profile as "Bob Bubbles" is listed in my contacts) How should I list my education and work history, such that I maximize anonymity while still providing potential employers something attractive?
