Cybersecurity remains a growing field in the legal arena. This field, however, can be difficult for a law student to enter, and I hope my points prove helpful in advising students in their endeavors. Since this is a brief introduction, I cannot cover every topic or detail—though I will write more later. I recommend that you conduct extensive research about the field—numerous articles exist online about how to become a cybersecurity lawyer—and consult with cybersecurity lawyers and IT professionals.
As a cybersecurity lawyer, one can work either as a litigator or advisor. What’s the difference between the two you ask? The lawyer who litigates also advises; however, the lawyer who advises usually does not litigate. At a minimum the advisor may assist a company or law firm with pre-litigation matters. With that said, if you seek to litigate, hone your legal skills in civil/criminal litigation.
You also cannot neglect learning about innovative technology, IT best practices, reviewing IT news, etc. As for cybersecurity news, Krebs on Security provides detailed news coverage on the latest cyber threats, cyber-attacks, and investigative journalism on cyber-related issues.
My suggestions below lean more toward gaining technical knowledge and skills.
