News & Views: Cyberintrusion—Happening Much Closer to You Than You Might Think!

According to the Internet Crime Complaint Center (IC3)2 (www.ic3.gov), cybercrimes are rising rapidly. In 2009, 336 655 cybercrime complaints were submitted to IC3, a 22.3% increase compared with 2008. Of these complaints, 146 663 were referred to law-enforcement agencies for further investigation. These referred cases represented a combined financial loss of $559.7 million. Although many may think these crimes were the results of careless individuals who fell for those “you just inherited a million dollars” scams, the reality is that if you have Internet connection, hackers have probably already attempted to attack the information stored in your computer. According to a report by Perkel (1), an average of 27 000 hacking attempts were made per day during the first quarter of 2010 at the San Diego Supercomputer Center of the University of California. The report also provides some practical tips to enhance cybersecurity. Despite the alarming number of incidents, hacking attempts can usually be blocked successfully by well-coded firewalls. Most computer hackers look for open access or a poorly coded firewall to steal or sabotage data and intellectual property. Therefore, information technology (IT) professionals should be hired to write protective firewalls. Sensitive data should be managed by a centralized IT team that can monitor traffic and limit access. E-mail should be encrypted when sending sensitive data. Computers should be password-protected and encrypted. These measures may seem quite straightforward, but many academic researchers do not endorse them because of limited funding to hire IT professionals and the inconvenience that comes with heightened security. For example, cybersecurity means that personal computers should not be allowed to handle sensitive data unless firewalls have been installed and the computers have been encrypted. In addition, the exchange of information between colleagues via cyberspace can no longer occur without professional encryption. Furthermore, researchers will not be able to install software as needed but will require authorization by an “administrator.” Many researchers therefore prefer the convenience and freedom of no IT professional oversight over the security of their data; however, the truth is that it only takes one successful intrusion to wipe out years, if not decades, of hard work. Is the convenience really worth it? The only way to protect intellectual property from hackers is to be proactive in implementing security measures and stopping the bad habits that may promote successful cyberintrusion. So, let's follow the advice from the IT professionals and secure our data. Internet Crime Complaint Center information technology. DO enable automatic operating-system updates. DO install and update your antivirus and anti-malware software, most of which is available for little or no cost from universities. DON'T run your computer with administrator privileges, but as a non-privileged user. Then, if somebody does hack into your computer, they cannot install anything. DO consider purging sensitive data from connected computers and confining them to offline machines. DO encrypt your hard drive, for instance with FileVault (Mac), TrueCrypt (Windows/Mac/Linux) or PGP Whole Disk Encryption (Windows/Mac/Linux). DON'T send sensitive data by standard e-mail. If you're not using encrypted e-mail, encrypt the material itself, for instance in a password-protected PDF. DO ensure all your applications are patched to the current level, for instance with Secunia's free Personal Software Inspector (Windows). DO password-protect your computer and smartphone. DON'T let your web browser remember your passwords; instead, use password vaults, such as KeePass and LastPass, which store them in encrypted databases. DO use strong passwords — or better, passphrases — that include both upper- and lower-case letters, numbers and symbols. Change passwords regularly, and don't use the same one for everything.
