Презентация на тему Cyber-safety basics

suggestions for protecting your personal information and computer from

cyber-attacks. Cyber-safety topics covered include:

to describe a set of practices, measures and/or actions

you can take to protect personal information and your computer from attacks.

At UC Davis, we have the Cyber-safety Program policy, PPM 310-22, (http://manuals.ucdavis.edu/ppm/310/310-22.htm) which establishes that all devices connected to the UC Davis electronic communications network must meet certain security standards.

As part of this policy, all campus units provide annual reports demonstrating their level of compliance.

Further, there are services in place to help all students, faculty and staff meet the cyber-safety standards. Specific information about these services is provided in this tutorial.

threats and the problems they can cause . .

on the previous slide, as part of the UC

Davis community
you may face a number of other consequences if you fail to take actions to protect
personal information and your computer. Consequences include:

actions you can take to protect personal information and

your computer. These actions will help you meet the UC Davis Cyber-safety Program policy standards.

By implementing all seven of these security measures, you will protect yourself, others, and your computer from many common threats.

In most cases, implementing each of these security measures will only take a few minutes.

You can find more about cyber-safety on the UC Davis Computer Security Web site (http://security.ucdavis.edu/).

Anti-virus Software
3. Prevent Identity Theft
4. Turn on Personal Firewalls
5.

Avoid Spyware/Adware

7. Back up Important Files

Additional information about each of the actions below is provided on slides 8-14. Faculty and staff should work with their technical support coordinator before implementing these measures.

6. Protect Passwords

(OS) (e.g., Windows XP, Windows Vista, Mac OS X)

and software programs (e.g., Microsoft Office applications).

Most new operating systems are set to download updates by default. After updates are downloaded, you will be asked to install them. Click yes!

To download patches for your system and software, visit:
Windows Update: http://windowsupdate.microsoft.com to get or ensure you have all the latest operating system updates only. Newer Windows systems are set to download these updates by default.
Microsoft Update: http://www.update.microsoft.com/microsoftupdate/ to get or ensure you have all the latest OS and Microsoft Office software updates. You must sign up for this service.
Apple: http://www.apple.com/support
Unix: Consult documentation or online help for system update information and instructions.

Be sure to restart your computer after updates are installed so that the patches can be applied immediately.

Install OS/Software Updates

viruses, install and run an anti-virus program like Sophos.

Periodically,

check to see if your anti-virus is up to date by opening your anti-virus program and checking the Last updated: date.

Anti-virus software removes viruses, quarantines and repairs infected files, and can help prevent future viruses.

UC Davis students, faculty and staff can get Sophos for their work and home computer for FREE on the Internet Tools CD (available from IT Express in Shields Library).

Sophos can also be downloaded for free from the UC Davis Software License Coordination Web site (https://my.ucdavis.edu/software/).

Social Security numbers, driver’s license numbers or other personal

identity information unless you know exactly who's receiving it. Protect others people’s information as you would your own.

Never send personal or confidential information via email or instant messages as these can be easily intercepted.

Beware of phishing scams - a form of fraud that uses email messages that appear to be from a reputable business (often a financial institution) in an attempt to gain personal or account information. These often do not include a personal salutation. Never enter personal information into an online form you accessed via a link in an email you were not expecting. Legitimate businesses will not ask for personal information online.

Order a copy of your credit report from each of the three major credit bureaus-Equifax, Experian, and Trans Union. Reports can be ordered online at each of the bureaus’ Web sites. Make sure reports are accurate and include only those activities you have authorized.

for a built-in personal firewall. If you have one,

turn it on. Microsoft Vista and Mac OSX have built-in firewalls. For more information, see:
Mac Firewall  
(docs.info.apple.com/article.html?path=Mac/10.4/en/mh1042.html)
Microsoft Firewall (www.microsoft.com/windowsxp/using/networking/security/winfirewall.mspx)
Unix users should consult system documentation or online help for personal firewall instructions and/or recommendations.

Once your firewall is turned on, test your firewall for open ports that could allow in viruses and hackers. Firewall scanners like the one on http://www.auditmypc.com/firewall-test.asp simplify this process.

Firewalls act as protective barriers between computers and the internet.

Hackers search the Internet by sending out pings (calls) to random computers and wait for responses. Firewalls prevent your computer from responding to these calls.

can slow down your computer or cause other problems.

Use

Spybot and Ad-Aware to remove spyware/adware from your computer. UC Davis students, faculty and staff can get Spybot and Ad-Aware for free on the Internet Tools CD (available from IT Express in Shields Library).

Watch for allusions to spyware and adware in user agreements before installing free software programs.

Be wary of invitations to download software from unknown internet sources.

make new passwords difficult to guess by avoiding dictionary

words, and mixing letters, numbers and punctuation.

Do not use one of these common passwords or any variation of them: qwerty1, abc123, letmein, password1, iloveyou1, (yourname1), baseball1.

Change your passwords periodically.

When choosing a password:
Mix upper and lower case letters
Use a minimum of 8 characters
Use mnemonics to help you remember a difficult password

Store passwords in a safe place. Consider using KeePass Password Safe (http://keepass.info/), Keychain (Mac) or an encrypted USB drive to store passwords. Avoid keeping passwords on a Post-it under your keyboard, on your monitor or in a drawer near your computer!

important files to a virus, computer crash, theft or

disaster by creating back-up copies.

Keep your critical files in one place on your computer’s hard drive so you can easily create a back up copy.

Save copies of your important documents and files to a CD, online back up service, flash or USB drive, or a server.

Store your back-up media in a secure place away from your computer, in case of fire or theft.

Test your back up media periodically to make sure the files are accessible and readable.

security cables and locking doors and windows in the

dorms and off-campus housing.

Avoid leaving your laptop unsupervised and in plain view in the library or coffee house, or in your car, dorm room or home.

Set up a user account and password to prevent unauthorized access to your computer files.

Do not install unnecessary programs on your computer.

Microsoft users can download the free Secunia Personal Software Inspector (https://psi.secunia.com/), which lets you scan your computer for any missing operating system or software patches and provides instructions for getting all the latest updates.

technical support coordinator before implementing new cyber-safety measures.

Talk with

your technical support coordinator about what cyber-safety measures are in place in your department.

Report to your supervisor any cyber-safety policy violations, security flaws/weaknesses you discover or any suspicious activity by unauthorized individuals in your work area.

Physically secure your computer by using security cables and locking building/office doors and windows.

Do not install unnecessary programs on your work computer.

C. It’s most likely that you downloaded spyware and/or adware.
Firewalls
OS and/or software updates (patches)

How did you do?

8-7 correct: Fantastic! You can help write the next quiz!
6-5 correct: Good. You can help write the next quiz, but we’ll check it for accuracy . . . just in case.
4-3 correct: You might want to review the material for the questions you missed.
