1 2008 CAMS-ii Users Conference CAMS-ii and Technology The Good, The Bad, The Other

2 Technology Topics LAN, WAN, WLAN, WWAN Firewalls Intrusion Detection Encryption Phishing Anti-Virus, Anti-Spyware And some other stuff.

3 Technology Technology is changing at a brisk pace. Moore s Law In 1965 Intel co-founder Gordon Moore predicted that the number of transistors on a chip will double about every two years. Computers are more powerful, less expensive, and become obsolete sooner More ways to get it done better, faster, and cheaper. As hardware capabilities increase, software is modified to need more hardware capability the cycle continues

4 Upgrade or Replace?

5 Networks LAN Local Area Network Inside the building (Intranet) WAN Wide Area Network Outside the building (Internet) WLAN Wireless LAN WWAN Wireless WAN

6 Typical Network Layout

7 Typical Network Layout

8 Typical Network Layout

9 Firewall Firewalls protect your network Keep unwanted traffic and data out Hackers, viruses, spyware, etc. Hardware and Software Solutions Routers Security Appliances Gateway Computer (Proxy Server) Individual Computer Programs

10 Hardware Firewall The NAT Router Network Address Translation Linksys, Dlink, Netgear Inexpensive Blocks unwanted entry Hides networked computers Typically does not watch outbound

11 Hardware Firewall A popular wireless router from Linksys

12 Hardware Firewall The security appliance Cisco, Sonicwall, Watchguard More expensive Provides all basic router functions Adds additional monitoring and prevention tools Anti-virus, anti-spyware, content filter Intrusion detection / prevention Outbound monitoring

13 Intrusion Detection / Prevention IDS / IPS adds to the firewall capability IDS watches for suspicious activity IPS stops suspicious activity

14 IDS/IPS Sample Reports

15 IDS/IPS Sample Reports

16 IDS/IPS Sample Reports

17 IDS/IPS Sample Reports

18 IDS/IPS Sample Reports

19 IDS/IPS Sample Reports

20 IDS/IPS Sample Reports

21 IDS/IPS Sample Reports

22 Software Firewall The proxy server Network Computer with firewall All other computers get to the internet through it Provides all basic router functions Works like a router May slow down network traffic More complex to configure

23 Software Firewall Firewall software on a pc Norton, McAfee, Zone Alarm Can identify rogue software Difficult to configure Interferes with internal networking Resource hog Useful if configured properly

24 Encryption Protects data from prying eyes Free or cost-based Truecrypt Ccrypt Most necessary with removable media USB devices CD/DVD media CAMS-ii External Backups are encrypted

25 Security at the Desktop Safeguard your data Notebooks are risky USB Flash Drives are even riskier Don t forget to back up the pc!! USB external hard drive CD/DVD media Network storage Education is important

26 Phishing and Pharming Phishing Lures people to give up personal information looks official Pharming Misdirect to fake web site Modification of hosts file

27 Malware Viruses and Trojan Horses May turn your pc into a spam machine Spyware May log keystrokes and send home Spam HUGE irritant and wastes time Protection Network Individual PC

28 is NOT secure!!!! You never know who might be reading your

29 Secure Can Be Simple or Complicated; Expensive or Inexpensive Personal Security Certificate (SSL) Cumbersome Limited Functionality Password Protected Files Zip Files (less secure) Encryption Software Freeware (less integrated) Cost-Based (more integrated)

30 File Encryption Encrypt the file, then send it as an attachment Cryptainer LE and DeCypherIT are free programs used for this example. Cryptainer LE limits file size to 25mb more than sufficient Use DeCypherIT to decrypt the file OR. Create an ecrypted.exe file to send Many firewalls and clients block.exe files

35 How Security Measures Affect CAMS-ii CAMS-ii is on the Intranet Internet Explorer Trusted Sites Zone ActiveX Controls Toolbars and Popup Blockers Can affect CAMS-ii behavior Learn how they work Anti-Virus / Anti-Spyware Can stop approved controls

36 How Security Measures Affect CAMS-ii Software Firewalls on PCs Accessing shared resources Printing File transfers Where is CAMS-ii? The Windows hosts file

37 Automatic Windows Updates Controversial Can fix problems Can cause problems Recommendations Auto-download, manual install Read install notes

38 Windows Vista Moving to new computers is never much fun for most of us It s not if it s when Higher hardware requirements Lots of memory (RAM) Robust video capability Will my programs work? Will CAMS-ii work?

39 Windows Vista Which version to use? Home Basic Very Basic not recommended Home Premium Supports multimedia (Windows Media Center) Will not work in a Windows Domain Business Will work in a Windows Domain Does not have all the multimedia features Ultimate Everything included (even the batteries!)

40 Windows Vista User Access Control What is it? Can I turn it off? Changes to file locations in CAMS-ii Allows more flexibility for securing the PC

41 Miscellaneous
