Little mistakes can make for big problems for IT professionals ““ this slideshow on CIO.com lists twenty ways that mistakes can be made by even the most savvy IT staff or organizations. For instance, a common mistake is to set up your outsourcing strategy poorly. This can lead to wasted time and money. Many IT organizations will not allow mission critical operations to be performed anywhere but in-house – and that’s a great way to let your competitors get the edge on you. Another big mistake comes in IT Security: are you remembering to consider the human element?: Today’s network admins have access to a dizzying array of security tools. But as hacker Kevin Mitnick is fond of saying, the weakest link in any network is its people. The most fortified network is still vulnerable if users can be tricked into undermining its security — for example, by giving away passwords or other confidential data over the phone. For this reason, user education should be the cornerstone of your IT security policy. Make users aware of potential social engineering attacks, the risks involved, and how to respond. Furthermore, encourage them to report suspected violations immediately. In this era of phishing and identity theft, security is a responsibility that every employee must share. Another mistake that many fall into is “creating indispensable employees.” It’s nice to have an employee who can fix anything and understands all of your systems, but what is going to happen if they leave and you relied only on them for operations? Instead, build a multi-talented work force and prevent your organization from relying on just one person.
