Disinhibition

In the online environment, people may feel that they can be less careful than they might be in an offline environment.

Domain Name

Domain names are used in Universal Resource Locators (URLs) to identify particular web pages or sites located on the Internet. For example, the domain name netsafe.org.nz represents the website for NetSafe.

The ownership of a domain name can often be researched by performing a ‘Whois’ search (www.whois.net) allowing you to evaluate the length of time a website has been in existence and the people or company behind the site.

A private or anonymous registration record or newly established site could indicate suspicious behaviour.

Download

Refers to the process of receiving information via electronic means.

Take care to always download files from reputable sources – ensure you scan downloads with anti-virus software before opening and avoid downloading files from web links sent to you in spam or phishing emails as they may be designed to infect your computer with malware.

E

Email

Short for electronic-mail, and refers to the electronic transmission of personal or group messages.

It’s important to protect your email account with a strong password, especially if you use a free webmail service and to avoid the common phishing tactic of confirming your login details by clicking on the link in a spam or fake email message.

Sending out spam or phishing messages is a common way for cyber criminals to gain access to your account to then send further spam or scam messages to your friends and family.

Encryption

Encryption is a method of scrambling data so that it cannot be read without knowing the password or ‘key’ to unscramble it.

Sensitive data stored on laptops or backup media should be encrypted to keep personal or business information private and secure.

Firewall

A firewall is an electronic boundary (or a physical piece of hardware) that prevents unauthorised users and packets of data or information (such as files and programs) from accessing a protected system.

You should ensure your computer’s firewall is turned on to help prevent common computer system attacks.

Flaming

Refers to the act of making deliberately insulting comments via online mediums. A ‘flame war’ occurs when such comments are traded backwards and forwards.

Forensic audit

A forensic audit is an audit of computer systems by a forensic specialist.

A forensic auditor will uncover extremely detailed information about how a computer system has been used, and can be invaluable during the investigation of a serious cybersafety or security incident.

Friends

In social networking terms this can refer to contacts, and does not necessarily mean friends like the offline sense. For example, on social networking sites, accepting a stranger’s invitation will add them to your ‘friend’ list.

Younger internet users should be encouraged to only ‘friend’ people they know or have met in real life and to not give out personal data or share photos with new online friends.

ICT is a broad term used to refer to any technology that could be considered a communication device including radio, internet and satellite systems. ICT is used to denote technological devices like computers, mobile phones, wireless internet enabled devices and gaming consoles.

Instant Messaging (IM)

Refers to live, text-based communication between two or more people. This feature is now offered by many websites to allow users to chat in realtime.

Internet or Cyber Cafés

Businesses where several computers are available to rent on site, usually for accessing the internet. The computers may also be linked to one another to allow users to play multi-player games.

You should ensure when using a public internet cafe computer that you do not store password or login details in the browser – it is beneficial to delete your browsing history, cookies and other login data to avoid anyone else from gaining access to your accounts.

Internet Service Provider (ISP)

An ISP is a company that provides commercial access to the internet. For example, Telecom, Vodafone and Orcon are all New Zealand ISPs.

ISPs may also provide web hosting and other services and should be your first point of contact when experiencing slow internet speeds.

Intranet

An intranet is a private, internal network that provides users access to files, applications, and services within a school or workplace without needing to go ‘out’ onto the Internet.

IP Address (IP)

An IP address is a numerical identifier for a computer or device on a TCP/IP network. (TCP stands for Transmission Control Protocol).

You should be aware that your internet activity is frequently logged according to your computer’s IP address and this can be used to identify you if you break New Zealand laws.

TCP/IP networks route messages according to the destinations’ IP addresses. Within a private network, IP addresses can be assigned at random as long as each one is unique. However, connecting a private network to the Internet requires using publicly registered IP addresses (called Internet addresses) to avoid duplications.

IRC

Short for Internet Relay Chat, which is a form of instant messaging, where users can talk in chat rooms or send private messages to other users.

IT

Short for Information Technology, and refers to those involved in the implementation and security of computer-based information systems.

O

Objectionable material

Defined in New Zealand by the Films, Videos and Publications Classification Act 1993. Broadly speaking, the act defines a publication to be objectionable if it deals with “matters such as sex, horror, crime, cruelty, or violence in such a manner that the availability of the publication is likely to be injurious to the public good.”

You can report objectionable material you encounter online at the Orb website, www.theorb.org.nz

Online grooming

Has the same goal as offline grooming, but differs in many ways, including giving the groomer access to more potential victims, access to more information (for example by reading someone’s blog or social networking profile), the ability to mask their true identity, potential for 24/7 access, covert access (less risk of discovery and use of technology such as spyware to gain information).

The perceived anonymity of the internet can make people take greater risks and allow relationships to develop faster.

Online world

Concerns actions which take place in cyberspace, as opposed to in the offline world.

Because many activities such as socialising, dating and shopping can be done both online and offline, many young people who have grown up with this do not consider the online world to be less real than the offline world.

Open source

Normally refers to software where the license permits distribution and modification of the original software – it is not copyrighted.

Operating system (OS)

The operating system (OS) of a computer or smartphone contains the electronic instructions that control the computer and run the programs.

This software is usually specific to a type of computer, for example Windows, Unix, Linux, Mac OS X, Android, iOS.

The OS controls the hardware and software and should be regularly updated with system or software ‘patches’ that fix security vulnerabilities.

Computer users should consider upgrading to the latest version of their operating system when a new type is released to benefit from security improvements as well as new features.

P

Packet

A packet is a message fragment containing data or information. When messages are sent on the internet, they are broken into smaller, more easily transportable pieces called packets.

Each packet consists of a header (instructions) and a piece of the message. A single email may actually be broken into many different packets when being transmitted.

Password

A requirement for many online (and offline) services, e.g. email and internet banking.

To access the service you need to provide the correct username and password to login.

NetSafe suggest your password should be a minimum of 15 characters long and contain a mix of upper and lower case letters and symbols.

You should keep your passwords secret and change them regularly – you can use a password management tool if you have difficulties remembering a unique password for each online service.

Peer-to-Peer Network (P2P)

P2P is a network configuration in which each computer on the network has the same capabilities as the other computers on the network and any one of them can initiate a communications session with another.

Any peer can add files, copy them, and move them to any peer computer on the network (where people store their files on their own computers). Therefore, any person on the network can access those files, copy them, and move the copies over the network to another computer.

The 2011 Copyright (Infringing File Sharing) Amendment Act is a significant change to the Copyright Act 1994 and provides rights owners with a special regime for taking enforcement action against New Zealanders who infringe copyright through file sharing, specifically targeting peer-to-peer technologies.

Pharming

A malicious attack which can result in users being redirected from the intended website they wish to visit to a bogus website. This is often used to steal people’s personal information.

Pharming can be conducted either by changing the hosts file on a victim’s computer or by exploiting a vulnerability in DNS server software.

Drive-by pharming is where malware attempts to change the firmware or configuration software on a wireless router to redirect internet browsing – it is important to use a strong wireless router password and to ensure you do not leave the default, our of the box, login for the router administrator.

Phishing

The illegal act of trying to obtain people’s personal details, such as logins and passwords.

Phishing uses techniques such as Social Engineering to persuade you to click on a fake link to an online service you use. The fake website then records or harvests your login details.

An example email may say ‘Your online banking has been compromised. Enter your login and password to ensure your security’ – this is one of the most common computer security scams that relies on the weakness of the end user to succeed.

Plug-ins

Plug-ins are software pieces that add a specific feature or service to a larger system. For example, in order to view a PDF file, the Adobe Acrobat Reader® plug-in is required.

Software and browser plug-ins or ‘helper applications’ are very popular and as a result vulnerabilities can be can be targeted by cyber criminals as an easy way to breach your computer security.

NetSafe encourage you to update your software and all common plug-ins such as Adobe Reader and Flash to the latest version available.

Pop-up adverts

These are advertisements that appear in a separate browser window while a website is being viewed.

Profiles

Generally contain information which users want to be displayed to other users, e.g. photos, nickname, date of birth, interests etc.

Your social networking profile forms part of your digital footprint and it is important to make use of privacy settings to restrict access to your personal information to friends that you trust.

Your public profiles may contain sensitive information that can be used to guess your passwords or for Social Engineering or Spear Phishing type attacks.


Back to top


R

Ransomware

Ransomware is a form of malware that is designed to lock your data or lock up your computer so you are forced to pay the creator a fee to restore access.

Your computer or server may display a warning screen about pornography or copyright infringing files that have caused the system to be locked.

The warning about being reported to the police is designed to scare you into paying the ‘fine’- do not do this.

Ensure you have backups of all your important data and protect your computer or server with patches and anti-virus.

Register/registration

Typically refers to the act of signing up to something, whether it be joining a forum, requesting to receive a newsletter or signing up for internet banking.

Try to ensure when registering for new online services that any data you send is encrypted – look for a secure SSL connection signalled by a padlock icon or https:// website address.

You should always investigate what use will be made of your personal information to protect your privacy and children should not reveal their full name, age or address.

Router

A piece of hardware that redirects electronic traffic around a network.

Broadband routers sit between a network and the internet, sending and receiving data. Routers usually contain a built-in firewall, and can be either wireless, or wired (connected to other computers via cables).

The typical flow of incoming data from the internet on a small network is internet then router then server then other computers on the network.

Wireless routers should be protected by using strong encryption settings (WPA2), long and complex passphrases and by changing the default admin login.


Back to top


S

Search engine

Search tools such as Google make finding online information easier. They generally work by allowing users to enter key words or phrases to retrieve relevant information.

Search results for some keywords can return adult material and parents can investigate safe search options to try to filter content.

Occasionally websites that feature high in result lists can contain false information or try to download malware onto your machine so it is important to keep your browser and computer system and software up to date.

Sharing

In computer terms, this refers to sharing files such as music, images or video files.

Sharing can be done in many ways including physical media (CDs/USB sticks) and over local, internet and Peer 2 Peer networks.

Sharing files with others can result in the transmission of computer viruses or other malware infections so it is important to use up to date anti-virus software on your machine, to update your system and software and to regularly backup your important data.

SMiShing / SMS phishing

SMS phishing uses mobile phone text messages to deliver the bait to trick people into divulging their personal information. Due to small device screens which hide phishing URLs and the urgency of many messages, smishing can often be more effective.

A text message may direct the recipient to a seemingly legitimate website that asks you to “confirm” or enter your personal financial information such as your credit or debit card number, your CVV code (on the back of your credit card), your ATM card PIN, driving licence number, email address or other personal information.

Alternatively, you may be requested to reply by text or call a phone number that directs to a legitimate-sounding automated voice system, similar to those used by your bank, which will ask for the same kinds of personal information.

Text spam or smishing should be reported to the DIA. Do not click on website links or reply or attempt to ‘stop’ these kinds of texts, simply delete them.

Social Engineering

In computer terms, this refers to techniques designed to manipulate people in some way.

A common example used in phishing scams are fake emails designed to get the unsuspecting computer user to login to a fake banking website to expose their private information.

Oversharing your personal information on social networking sites or failing to make use of privacy settings can leave you exposed to more attacks.

Social Networking

Facebook is the most popular current example but there are many websites that allow users to set up a profile about themselves.

These profiles generally contain information about interests (as well as age, gender, etc.), and allow users to make friends with people.

Software

Refers to programs operating on a computer, which interact with other pieces of software (such as the operating system) and hardware to allow the computer to perform tasks.

Computer software vulnerabilities are sought out by cyber criminals to get access to your personal information, destroy data or make your computer part of a botnet.

It is important to update your software regularly and to turn on auto updates where possible to avoid leaving security holes open.

Spam

Spam is electronic junk mail or junk newsgroup postings. Some people define spam even more generally as being any unsolicited email. In addition to being a nuisance, spam also takes up considerable network bandwidth

NZ businesses and individuals are able to make complaints about spam to the Department of Internal Affairs’ Anti-Spam Compliance team at www.theorb.org.nz

Spoofing

The act of impersonating something or someone. For example, it is possible to falsify your email, IP address or website address to imitate somebody else’s.

Spoofing is often used for malicious purposes such as phishing and may be used by criminals involved in identity theft.

Spyware

Spyware is software that gathers information about people or organisations without their knowledge, to relay to advertisers or other interested parties. Typically it profiles a user’s web habits for marketing purposes.

A computer can get infected by spyware if the user installs rogue shareware programs. Most of these programs earn revenue by including the monitoring software in their distribution, and the makers will offer their programs ‘free’ to the user to encourage downloads

Up to date internet security software can help protect your machine from common spyware programs.

T

TCP/IP

Refers to communication protocols used to connect hosts or computers on the Internet.

TCP stands for Transmission Control Protocol, which is the main protocol in an IP (Internet Protocol) network.

Whereas the IP deals solely with packet switching, TCP/IP allows two hosts to communicate with long streams of data at one time, always guaranteeing the packets arrive in the correct order.

Temporary (Temp) files

Temporary files are created by applications such as Microsoft Word while a document is being created. These generally are erased when the document is saved or closed. However, in some cases a temporary file remains (generally with the file extension .tmp).

Temporary Internet Files are files that have been ‘collected’ while visiting Internet sites and these are usually stored (cached) on the local computer in the Temporary Internet Files directory.

Trojan/Trojan Horse

A type of malware which appears to be benign, but when executed (activated by the user) they are actually harmful. Trojans cannot activate themselves.


Back to top


U

Universal Resource Locator (URL)

A World Wide Web address composed of several parts indicating the protocol, the server where the ‘resource’ (such as a web page) resides, and possibly the path, and the file name of the resource.

An example of a URL is https://www.netsafe.org.nz, which is NetSafe’s URL.

Upload

Refers to the process of sending information via electronic means. This can include sending an email or publishing data such as a video on a website such as YouTube.

USB

Sockets were designed to standardise the way in which external devices were connected to computers, e.g. USB drives (external hard-drives), USB cameras and USB coffee warmers.

USB data sticks are a popular and cheap way to backup, store and transfer files but they can also be easily lost, hacked or infected.

Always encrypt important data on USB sticks and scan these storage devices and the data they carry for viruses and malware.

Use agreement

Refers to an agreement – written or verbal – detailing acceptable use of a given device or service.

NetSafe has templates for schools, businesses and community groups covering the usage of technology equipment to improve cyber safety and security processes.

User account

The relationship between a computer or network and a user.

The user account defines such things as access to email accounts or sensitive data. User accounts can also be used to customise how a computer interface (desktop) appears when a user logs on.

User accounts can be set up on individual computers or for networks on the server. Each computer user should ideally have a unique user account and parents can combine these with parental control tools to set times and internet access limits.

Username

Are a requirement for many online (and offline) services, e.g. email and internet banking. To access the service you must provide the correct username and password.

It is common for many services to set your email address as your username so be sure to choose a unique and strong 15 character password for every login you create.


Back to top


V

Viruses

A type of malware which can self-replicate and modify themselves. Viruses require user interaction in order to spread between computers.

Many viruses are designed to cause problems such as deleting data or crashing computers. Some are designed to display messages, or send spam to other computers.

Anti-virus software can clean viruses from computers and protect against re-infection – it is essential to keep virus definition files up to date.

It is important to always use an up to date browser and to keep your system and software updated to help avoid ‘drive-by downloads’.

Whitelist

A list of websites, terms or email addresses which have been identified as appropriate and will not be filtered.

Wi-Fi

Generally refers to wireless networks that allow multiple internet capable devices to share an internet connection.

It is important to secure wireless networks to avoid eavesdropping, hacking and freeloaders.

Use strong WPA2 encryption on your router, choose a strong passphrase for the network connection and change the default login details.

Remember to be cautious when joining free public Wi-Fi hotpsots and avoid shopping, banking online or reading sensitive emails.

Window

In computer terms this relates to your browser. When you open your browser, the page you see is called a window; the content in the window is the webpage.

Wipe

Documents and other data remain on the hard drive (or other storage such as a USB stick or tape) even after they have been deleted.

Wiping is the term used to describe the running of a piece of specialist software which overwrites the data at least seven times to ensure it can never be retrieved.

Wireless network
