Information Security Awareness

INFORMATI ON User Awareness and Practices SECURITY IMPORTANCE OF SECURITY The internet allows an attacker to attack from anywhere on the planet. Risks caused by poor security knowledge and practice: Identity Theft Monetary Theft Legal Ramifications (for yourself and districts) Termination if policies are not followed

According to www.SANS.org , the top vulnerabilities available for a cyber criminal are: Web Browser Instant Messenger (IM) Clients Web Applications Excessive User Rights SECURITY VS SAFETY Security: We must protect our computers and data in the same way that we secure the doors to our homes. Safety: We must behave in ways that protect us against risks and threats that come with technology. USER AWARENESS

System Administrators COMPUTER CRIMINALS Some scripts are useful to protect networks Hacker: Computer-savvy programmer creates attack software Script Kiddies: Computer users who know how to execute programs Criminals: Create & sell bots -> spam Sell credit card numbers, Hacker Bulletin Board SQL Injection Buffer overflow

Password Crackers Password Dictionaries Successful attacks! Crazyman broke into CoolCat penetrated Malware package=$1K-2K 1 M Email addresses = $8 10,000 PCs = $1000 LEADING THREATS Virus Worm Trojan Horse / Logic Bomb

Social Engineering Rootkits Botnets / Zombies VIRUS A virus attaches itself to a program, file, or disk When the program is executed, the virus activates and replicates itself The virus may be benign or malignant but executes its payload at some point (often upon contact) Viruses result in crashing of computers and loss Program A Extra Code

infects of data. In order to recover/prevent virus/attacks: Avoid potentially unreliable websites/emails System Restore Re-install operating system Anti-virus (i.e. Avira, AVG, Norton) Program B WORM Independent program which replicates itself and sends copies from computer to computer across network connections. Upon arrival the worm may be activated to replicate.

To Joe To Ann To Bob Email List: [email protected] [email protected] [email protected] LOGIC BOMB / TROJAN HORSE Ransomware: a type of malicious software designed to block access to a computer system until a sum of money is paid. Crypto-ransomware, encrypts certain file types on infected systems and forces users to pay the ransom through certain online payment methods to get a decrypt key.

Trojan Horse: Masquerades as beneficial program while quietly destroying data or damaging your system. Download a game: Might be fun but has hidden part that emails your password file without you knowing. SOCIAL ENGINEERING Social engineering manipulates people into performing actions or divulging confidential information. Similar to a confidence trick or simple fraud, the term applies to the use of deception to gain information, commit fraud, or access computer systems. Phone Call: This is John, the System Admin. What is your password?

Email: ABC Bank has noticed a problem with your account In Person: What ethnicity are you? Your mothers maiden name? and have some software patches I have come to repair your machine

PHISHING = FAKE EMAIL Phishing: a trustworthy entity asks via e-mail for sensitive information such as SSN, credit card numbers, login IDs or passwords. PHARMING = FAKE WEB PAGES The link provided in the e-mail leads to a fake webpage

which collects important information and submits it to the owner. The fake web page looks like the real thing Extracts account information BOTNET A botnet is a large number of compromised computers that are used to create and send spam or viruses or flood a network with messages as a denial of service attack. The compromised computers are called zombies MAN IN THE MIDDLE ATTACK An attacker pretends to be your final destination on the network. If a person tries to connect to a specific WLAN access point or web server, an attacker can mislead him to his computer, pretending to

be that access point or server. ROOTKIT Upon penetrating a computer, a hacker installs a collection of programs, called a rootkit. May enable: Easy access for the hacker (and others) Keystroke logger Eliminates evidence of break-in

(f) Other information that, alone or in combination, is linked or linkable to a specific student that would allow a reasonable person in the school community, who does not have personal knowledge of the relevant circumstances, to identify the student with reasonable certainty; or (g) Information requested by a person who the educational agency or institution reasonably believes knows the identity of the student to whom the education record relates. RECOGNIZING A BREAK-IN OR COMPROMISE Symptoms: Antivirus software detects a problem Pop-ups suddenly appear (may sell security software) Disk space disappears Files or transactions appear that should not be there System slows down to a crawl Unusual messages, sounds, or displays on your monitor Stolen laptop (1 in 10 stolen in laptop lifetime)

Your mouse moves by itself Your computer shuts down and powers off by itself Often not recognized MALWARE DETECTION Spyware symptoms: Change to your browser homepage/start page Ending up on a strange site when conducting a search System-based firewall is turned off automatically Lots of network activity while not particularly active Excessive pop-up windows New icons, programs, favorites which you did not add Frequent firewall alerts about unknown programs trying to access the Internet Bad/slow system performance

SAFE & SECURE USER PRACTICES SECURITY: DEFENSE IN DEPTH Defense in depth uses multiple layers of defense to address technical, personnel and operational issues. ANTI-VIRUS & ANTI-SPYWARE Anti-virus software detects malware and can destroy it before any damage is done Install and maintain anti-virus and antispyware software Be sure to keep anti-virus software updated Many free and pay options exist FIREWALL

A firewall acts as a wall between your computer/private network and the internet. Hackers may use the internet to find, use, and install applications on your computer. A firewall prevents hacker connections from entering your computer. Filters packets that enter or leave your computer PROTECT YOUR OPERATING SYSTEM Microsoft regularly issues patches or updates to solve security problems in their software. If these are not applied, it leaves your computer vulnerable to hackers. The Windows Update feature built into Windows can be set up to automatically download and install updates.

RECOMMENDATIONS Never use admin or root or administrator as a login for the admin A good password is: private: it is used and known by one person only secret: it does not appear in clear text in any file or program or on a piece of paper pinned to the terminal easily remembered: so there is no need to write it down at least 8 characters, complex: a mixture of at least 3 of the following: upper case letters, lower case letters, numbers and symbols not guessable by any program in a reasonable time, for instance less than one week changed regularly: a good change policy is every 3 months

AVOID SOCIAL ENGINEERING & MALICIOUS SOFTWARE Do not open email attachments unless you are expecting the email with the attachment and you trust the sender. Do not click on links in emails unless you are absolutely sure of their validity. Only visit and/or download software from web pages you trust. OTHER HACKER TRICKS TO AVOID

Be sure to have a good firewall or pop-up blocker installed Pop-up blockers do not always block ALL pop-ups so always close a pop-up window using the X in the upper corner. Never click yes, accept or even cancel Infected USB drives are often left unattended by hackers in public places. SECURE ONLINE BANKING & BUSINESS

Always use secure browser to do online activities. Frequently delete temp files, cookies, history, saved passwords etc. https:// Symbol showing enhanced security BACK-UP IMPORTANT INFORMATION No security measure is 100% What information is important to you?

PUT THIS KNOWLEDGE TO WORK! These are best practices involving Information Security. Most of these practices are from the National Institute of Standards and Technology. https://www.nist.gov/ Use these practices at home and at work to keep safe and secure. Districts have policies and procedures regarding secure practices. Be sure to understand them and adhere to them. It will protect you, your district and your students.
