Windows PCs have a vast library of software for essentially every purpose. Macs have less of a collection, however, Apple is best known for software written specifically for the creative professional market, including journalism and desktop publishing, video editing and audio editing. In addition, there have been inroads into the educative and scientific research sectors.

Threats

7. Computer Security: Concepts and Basics

• Vulnerabilities.

• Flaws in computer software that create weaknesses • Improper computer or security configurations

• Malware • Malicious code that includes viruses, worms and Trojan horses

• Spyware • Software that unbeknownst to you, gathers and sends to third parties, information and data about

you and your computer activities.

• Spam • Can be used to deliver email that could contain Trojan horses, viruses, worms, spyware and targeted

attacks aimed at obtaining sensitive, personal identification information.

• Phishing

• Essentially an online con game. • Uses spam, malicious Web sites, email messages and instant messages to trick people into divulging

sensitive information, such as bank and credit card information or access to personal accounts

• ADWare • Software which automatically plays, displays, or downloads advertisements

• KeyLogging • capture and record user keystrokes. The data captured is then transmitted to a remote computer.

7. Security, Data Backup/Recovery and Disaster Planning

• Physical Access

• Standard vs. Administrative User

• User Access Control

• Passwords

• Anti-Virus

• Firewall

• Application Updates / Patches

Onion Approach: Protection in Layers

[email protected]


16

Best Practice


• Standard vs. Administrative User • “Rule of least privilege" / “Separation of duties."

• No More Passwords! • Hackers use techniques such as brute force and dictionary look-up

• Passwords of 8 characters or less are crackable in seconds.

• Instead, think Passphrase

• Essentially a sentence, including spaces, that you employ instead of a single pass "word.“

• Should be at least 15 to 25 characters in length (spaces count as characters)

• Memorable phrase, that works for you, that is unlikely to be found in a dictionary

• Should never contain information that would identify you personally

• Change passwords regularly

• Never use the same password twice, Ever!

Disaster Recovery and Planning What is Your Data Worth to You?

• Have a Plan! − Backup is Insurance − Part of Continuation of Business Plan − Part of your Business Plan − Someone in charge

• Back-Up Your Data

− Choose − Automated. − Daily/Regular back-ups. − Store in off-site, secure location. − Test Backup Plan regularly and adjust.

• Backup Methodology

− Flash Drive − USB Disk − Network Attached Storage − iCloud − CrashPlan − SkyDrive/OneDrive − Drop Box − Google Drive − Carbonite − iDrive

• Power, ISP, Etc.
