TAX-AIDE Computer Security ● Physical security Stolen computers ● Electronic security Theft via software Theft via networks 2 NLT Meeting Aug 2014

TAX-AIDE Consequences of Data Loss ● Affected taxpayers individually contacted and given free credit monitoring for a year at program’s expense NLT Meeting Aug TaxWise Online - no data stored on computers

TAX-AIDE Security – What You Can Do ● ALL computers used for Tax-Aide must be password protected. Passwords must not be shared outside the program. Written password reminders must be kept away from the computers SMT/TCS Training - Dallas5

TAX-AIDE Data Security Password ● Password guidelines: ● Minimum length – eight (8) characters for Windows, and TaxWise™ accounts. ● At least one letter and one number in the password. ● Choose a password that is not a dictionary word or someone’s name. ● Do not use TaxWise, TW, Tax-Aide, AARP or any word in the password similar to something that is obviously related to the program SMT/TCS Training - Dallas6

TAX-AIDE The Rising Malware Threat 7 NLT Meeting Aug 2014

TAX-AIDE 8 NLT Meeting Aug

TAX-AIDE What is Malware? ● Trojan, Virus, Worm, Backdoor, Botnets ● RansomWare ● Personal and account information theft Bank account withdrawal, credit card usage, loan falsification ● Ad clicking for Dollars 9 NLT Meeting Aug 2014

TAX-AIDE Methods of infection ● attachments ● web links ● Infected web sites ● Flash drives ● Adding an infected system to a network (Windows XP) ● Java installed – rapidly becoming one of biggest risks (this is different than javascript). 10 NLT Meeting Aug 2014

TAX-AIDE Nightmare Scenario ● A key logger ● Captures every account login ● Sends every keystroke made on the computer to a criminal enterprise Server. ● Every tax return done on the computer will result in identity theft on those SSNs 11 NLT Meeting Aug 2014

TAX-AIDE Effects of Identity Theft ● For victims of identity theft, consequences can last for years; causing financial problems, credit issues, benefit losses, and legal problems. ● Cost to the AARP Foundation Tax-Aide program reputation and the good work that you all do. ● Cost of credit protection. NLT Meeting Aug

TAX-AIDE Infected System Recognition ● Anti-virus software increasingly ineffective Polymorphic and “kit” virus production ● Where one virus exists there will be many due to backdoor access ● Look for Excessive ads, multiple IE toolbars, unusual home pages, slow system performance, problems running anti-virus scans ● Silent key loggers are the most dangerous and most undetectable If Tax-Aide becomes “targeted”, we will be infected and there is nothing we can do except re-image 13NLT Meeting Aug 2014 IF IN DOUBT RE-IMAGE

TAX-AIDE Windows XP ● The tech industry is assuming that every single existing Windows XP system will become infected with malware over the next few months. Infected websites Flash drives 14 NLT Meeting Aug 2014

TAX-AIDE What Can You Do ● Make sure all computers are running the Windows 7 or 8; this includes personal and site computers. ● Windows Vista not supported by CCH ● If a personal or site computer cannot be upgraded They must not be used for Tax-Aide purposes. They cannot be on the same network segment as Taxaide computers. If necessary contact the National Office. NLT Meeting Aug

TAX-AIDE What Can Be Done? ● Do all Windows, Adobe updates immediately ● Use anti-malware software like MSE and MalwareBytes ● If installed, remove Java ● Stick to mainstream, branded websites on Tax- Aide systems ● Re-Image systems regularly ● Run as a “standard” user – see later 16NLT Meeting Aug 2014 Too much effort for many – we have infected systems in the program right now!!

TAX-AIDE Site Visits ● All site visits by RCs and SCs should include the question ● “Are any Windows XP systems being used?” If yes take whatever action necessary to remove them ● “Are any systems behaving oddly?” Request technical help to check out the system. 17NLT Meeting Aug 2014

TAX-AIDE What else can be done? ● A policy change Windows user account passwords must be changed yearly ● 90% plus of malware will be stopped by using a “standard” Windows account!! – this includes silent key logger installation!! 18NLT Meeting Aug 2014

TAX-AIDE Windows Users ● Administrative User (e.g. Volunteer) Our everyday default, allows easy program and update installation ● Standard User Allows all usage of TaxWise and other software Does NOT allow any software installation or updating to be done. An Administrator user password must be entered to allow installation and updates 19NLT Meeting Aug 2014

TAX-AIDE NTC Recommendation ● Use a standard User Volunteer Account for all everyday purposes ● Only a best practice recommendation, not mandatory ● Will be in this fall’s Sharenet documents update. 20NLT Meeting Aug 2014

TAX-AIDE Why Recommendation ● The changes are simple if the user is comfortable using Windows Control Panel Many of our volunteers are not capable of this!! ● The change causes the inconvenience of having to type in a password to do the required Windows updates Many volunteers will find this unacceptable ● This change ONLY prevents new infections! Re-imaging is the only way to remove existing anti-virus proof infections! 21NLT Meeting Aug 2014
