Professional Associations
Those of you who have been in the IT industry for years are probably already familiar with most professional organizations. Some of the more popular include ISSA (Information Systems Security Association), USENIX/SAGE, ACM, IAPSC, and countless others. Most organizations require it’s members to pay dues, but that is not without value. Because there are so many different organizations, it is a better idea to pick one or two and get heavily involved. Many organizations are worldwide, but have local chapters. This provides many opportunities for benefit.
Did you ever wish you knew the right people? Local chapter meetings are great for professional networking. Some organizations have quarterly meetings, others hold them monthly. Chapter events are a great opportunity to meet people that have similar interests and needs. If you are in search for a specific security solution, often you will find someone at a meeting who can offer it. Conversely, if you’re a business owner and wish to extend your services, meetings can be helpful.
Organizations such as the ISSA offer educational benefits. Usually meetings include a lecture that is centered around an information security topic. Other meetings can include practical demonstrations and round-table discussions. Also, ad hoc study groups are often formed to prepare for certification exams.
Do you need additional credentials on your resume/cv? Do you wish you could prove to management that you are ready for a leadership position? Professional organizations also offer its members the chance to lead. Positions such as chapter president, vice president, secretary, etc. open for election each year. Although time consuming, it can be a worthwhile commitment.
Finally, most professional organizations have monthly/quarterly journals that are written by members. Rather than being subject to corporate pressures, you’ll find the articles in these journals are of high quality and relatively unbiased. Usually you can also find archives of past papers/publications on each organization’s Web site.
