Andmete turvalisus

Ülevaade probleemist

• Pilvepõhise teenuse puhul kasutatakse kolmanda isiku riist- ja tarkvara ning teenust pakutakse lepingu või koostöökokkuleppe alusel.
• Paljud tasuta teenused sisaldavad reklaame või nende osutamise käigus edastatakse isikuandmeid müügiks kolmandatele isikutele.
• Paljud videokoosolekute ja -loengute lahendused on veel väljatöötamisel ning neis leitakse tihti turvavigu. Tarkvara küll uuendatakse, aga vanemad versioonid võivad sisaldada ohtlikke turvaprobleeme, mida pahalased on hakanud kurjasti ära kasutama.
• Internetis on hakanud levima mitme tuntud tarkvara põhjal loodud võltsitud tarkvarapaketid, mis sisaldavad lisaks algsele tarkvarale kurjategijate lisatud pahavara.

Frequently asked questions on cybersecurity 

IT Helpdesk contact information 

University of Tartu IT Helpdesk: 

• working hours   Mon–Fri 8–18 

• phone                +372 737 5500 

• short number     5500 

• e-mail                arvutiabi@ut.ee 

Rules and requirements 

• Keep informed of the rules governing the use of information systems and cybersecurity.
• See https://siseveeb.ut.ee/et/tugitegevused/dokumendid-ja-juhendid-4 If necessary, consult IT Helpdesk or the chief information security officer. 

Data security 

• Be aware of data you hold in connection with your duties and ensure the security of data. If the data given to you to perform a task are no longer needed, delete them from your computer. 

Computer security 

• When you leave your computer, lock the screen. For Windows PC, hold down the Windows key and tap on the L key. 

• Make sure that a security software (Symantex Endpoint Protection) is used and running on your work computer and the latest versions of web browsers have been installed. If necessary, ask for advice from IT Helpdesk. 

• Avoid using public (unencrypted) Wi-Fi connection in your laptop, or if it is necessary, use a VPN connection. 

• If you work in a place where other people can see what is on your computer screen, we recommend using a privacy filter on your screen. 

• If possible, use data (disk) encryption on laptop and smart devices.  

• Never leave your laptop unattended or in an unlocked room outside the office. If the device is stolen, immediately inform IT Helpdesk and change your password as soon as possible for security reasons. 

• If you suspect that you may have run a program or opened a document containing malware (unusual error message, disturbing ads, etc.), contact IT Helpdesk immediately. 

• Make sure your personal device uses secure and up-to-date software. Update the software if necessary. See also recommendations in section 4!
• Use web-based (cloud-based) software solutions offered by UT to process work-related information
  
• Do not keep work information on a personal device for longer than necessary for remote work.
  

E-mail security 

• When you send an e-mail, select the recipients carefully – check whether all recipients need to be involved (especially when you reply to an e-mail) and whether the recipients' e-mail addresses are correct. 

• If you receive an e-mail from a person or a company you do not know, use caution when opening attachments and web links in the message. If necessary, consult IT Helpdesk. 

• If you receive an e-mail which tells you to update your password, be careful and, if necessary, consult IT Helpdesk. 

• If you have opened a suspicious link, immediately contact IT Helpdesk. 

Recommendations for securing cloud-based video conferencing and video lectures

Overview of the problem

• The cloud-based service uses third-party hardware and software and service is provided to end users under a contract or partnership agreement.
• Many free services contain advertisements or transfer personal information for sale to third parties.
• Many video conferencing and video lecture solutions are still under development and often contain security flaws. Software is being updated, but older versions may contain dangerous security issues that have been exploited by malicious people.
• Counterfeit software packages based on a number of well-known software programs, which contain malware added by criminals in addition to the original software, have become widespread on the Internet.
• Here are some examples of security issues:

      Security recommendations

• If your scheduled video meeting or video lecture contains sensitive information that should cause significant harm to the public, review the cloud-based service agreement or collaboration agreement and assess the potential risks. If in doubt, seek advice from IT Helpdesk!
• If possible, organise your video meetings and lectures in private mode. For example, restrict access to a meeting or lecture to persons with a University of Tartu username. Do not allow strangers to join the meeting.
• Do not distribute web links to your private meetings or lectures through social media channels. Use only the university’s e-mail and internal web channels to disseminate such information.
• If the meeting is with a wider audience, check who can join the meeting and who has the right to present or share screen. Find out how you can remove strangers or mistakenly connected parties from the meeting. If necessary, seek help from user manuals or call IT Helpdesk.
• Make sure you always use the latest version of the video conferencing software.
• Install the software only from the official channel (through the manufacturer's website or through the operating system's application store). If in doubt about the authenticity of the software, contact IT Helpdesk.

If you have any information security problems or questions, contact IT Helpdesk immediately. Document as accurately as possible the content of the incident, the time of its occurrence and, if possible, take a screenshot of the program’s screen.

Passwords 

• The rules for creating a password are available on Change your password page. 

• Change your password regularly (at least once in two years) and change it immediately when you suspect your password has become known to someone else. 

• It is safe to change your password at https://passwd.ut.ee. 

Workplace/office security 

• If you see a suspicious person on the premises, find out who they are and where they want to go.
• If necessary, inform the UT security service of your suspicions at +372 737 5111. 

Data protection 

In matters of data protection at the University of Tartu, consult Senior Specialist of Data Protection Terje Mäesalu: 

• phone: +372 737 5119 

• e-mail: terje.maesalu@ut.ee 

What to do in case of cybersecurity emergencies
